Emergence of human resilience in coastal ecosystems under environmental change
Provedor de dados: 7
Autores: Matin, Nilufar; Stockholm Environment Institute, University of York; neela.matin@york.ac.uk; Taylor, Richard; Stockholm Environment Institute, Oxford Centre; richard.taylor@sei-international.org.
Resilience has been studied in a number of disciplines, predominantly in psychosocial and ecological sciences. Although there are striking similarities in their approaches, the psychosocial tradition has centered on the family and its immediate surroundings, whereas the social-ecological approach has focused on macrosystems that stop at the family level. Recently, the need for bridging these gaps has been echoed by researchers from both these traditions, particularly for promoting resilience of individuals and their wider environment in the context of natural disasters and climate change. However, a new synthesis of social-ecological and behavioral theories integrating multiple dynamic systems that interact across levels is strikingly rare. We addressed...

Complexity and uncertainty are inherent in social-ecological systems. Although they can create challenges for scientists and decision makers, they cannot be a reason for delaying decision making. Two strategies have matured in recent decades to address these challenges. Systems thinking, as embodied by conceptual modeling, is a holistic approach in which a system can be better understood by examining it as a whole. Expert elicitation represents a second strategy that enables a greater diversity of inputs to understand complex systems. We explored the use of conceptual models and expert judgments to inform expansion of monitoring around oil sands development in northern Alberta, Canada, particularly related to migratory forest birds. This study area is a...

Ecohealth and resilience thinking: a dialog from experiences in research and practice
Provedor de dados: 7
Resilience thinking and ecosystems approaches to health (EAH), or ecohealth, share roots in complexity science, although they have distinct foundations in ecology and population health, respectively. The current articulations of these two approaches are strongly converging, but each approach has its strengths. Resilience thinking has developed theoretical models to the study of social&amp;#8211;ecological systems, whereas ecohealth has a vast repertoire of experience in dealing with complex health issues. With the two fields dovetailing, there is ripe opportunity to create a dialog centered on concepts that are more thoroughly developed in one field, which can then serve to advance the other. In this article, we first present an overview of the ecohealth...

Resource Transitions and Energy Gain: Contexts of Organization
Provedor de dados: 7

Energy gain constrains resource use, social organization, and landscape organization in human and other living systems. Changes in energy gain have common characteristics across living systems. We describe these commonalities in selected case studies involving imperial taxation, fungus-farming ants, and North American beaver, and propose a suite of hypotheses for the organization of systems that subsist on different levels of energy gain. Organizational constraints arising from energy gain predict changes to settlement and organization in postcarbon societies.

We explore the impact of &amp;#8220;game changers&amp;#8221; on the dynamics of innovation over time in three problem domains,  that of wilderness protection, women&amp;#8217;s rights, and assimilation of indigenous children in Canada. Taking a specifically historical and cross-scale approach, we look at one social innovation in each problem domain.  We explore the origins and history of the development of the National Parks in the USA, the legalization of contraception in the USA and Canada, and the residential school system in Canada.  Based on a comparison of these cases, we identify three kinds of game changers, those that catalyze social innovation, which we define as &amp;#8220;seminal,&amp;#8221; those that disrupt the continuity of social...

We aimed to contribute to the field of natural resource management (NRM) by introducing an alternative systemic context-based framework for planning, research, and decision making, which we expressed practically in the development of a decision-making &amp;#8220;tool&amp;#8221; or method. This holistic framework was developed in the process of studying a specific catchment area, i.e., the Sand River Catchment, but we have proposed that it can be generalized to studying the complexities of other catchment areas. Using the lens of systemic resilience to think about dynamic and complex environments differently, we have reflected on the development of a systemic framework for understanding water and livelihood security under transformation in postapartheid...

Can Resilience be Reconciled with Globalization and the Increasingly Complex Conditions of Resource Degradation in Asian Coastal Regions?
Provedor de dados: 7
Autores: Armitage, Derek; Wilfrid Laurier University; darmitag@wlu.ca; Johnson, Derek; Centre for Maritime Research; dsjohnson@marecentre.nl.
This paper explores the relationship between resilience and globalization. We are concerned, most importantly, with whether resilience is a suitable conceptual framework for natural resource management in the context of the rapid changes and disruptions that globalization causes in social-ecological systems. Although theoretical in scope, we ground this analysis using our experiences in two Asian coastal areas: Junagadh District in Gujarat State, India and Banawa Selatan, in Central Sulawesi, Indonesia. We present the histories of resource exploitation in the two areas, and we attempt to combine a resilience perspective with close attention to the impact of globalization. Our efforts serve as a basis from which to examine the conceptual and practical...

The action cycle/structural context framework: a fisheries application
Provedor de dados: 7
Autores: Webster, D.G.; Dartmouth College; D.G.Webster@Dartmouth.Edu.
There is a growing consensus that environmental governance is a wicked problem that requires understanding of the many linkages and feedbacks between human and natural systems. Here, I propose an action cycle/structural context (AC/SC) framework that is based on the concept of responsive governance, in which individuals and decision makers respond to problems rather than working to prevent them. By linking agency and structure, the AC/SC framework points out two key problems in the realm of environmental governance: the profit disconnect, whereby economic signals of environmental harm are dampened by endogenous or exogenous forces, and the power disconnect, whereby those who feel the costs of harm are politically marginalized and so have little influence...

Developing a new specialization&amp;#8212;Integration and Implementation Sciences&amp;#8212;may be an effective way to draw together and significantly strengthen the theory and methods necessary to tackle complex societal issues and problems. This paper presents an argument for such a specialization, beginning with a brief review of calls for new research approaches that combine disciplines and interact more closely with policy and practice. It posits that the core elements of Integration and Implementation Sciences already exist, but that the field is currently characterized by fragmentation and marginalization. The paper then outlines three sets of characteristics that will delineate Integration and Implementation Sciences. First is that the...

Improving our ability to manage complex, rapidly changing social-ecological systems is one of the defining challenges of the 21st century. This is particularly crucial if large-scale poverty alleviation is to be secured without undermining the capacity of the environment to support future generations. To address this challenge, strategies that enable judicious management of social-ecological systems in the face of substantive uncertainty are needed. Several such strategies are emerging from the developing body of work on complexity and resilience. We identify and discuss four strategies, providing practical examples of how each strategy has been applied in innovative ways to manage turbulent social-ecological change in South Africa and the broader region:...

Management of social-ecological systems takes place amidst complex governance processes and cross-scale institutional arrangements that are mediated through politics of scale. Each management scenario generates distinct cross-scale trade-offs in the distribution of pluralistic values. This study explores the hypothesis that conservation-oriented management scenarios generate higher value for international and national scale social organizations, whereas mixed or more balanced management scenarios generate higher value for local scale social organizations. This hypothesis is explored in the management context of Ruaha National Park (RNP), Tanzania, especially the 2006 expansion of RNP that led to the eviction of many pastoralists and farmers. Five...

There is a growing interest in assessing ecosystem services to improve ecosystem management in landscapes containing a mix of different ecosystems. While methodologies for assessing ecosystem services are constantly improving, only little attention has been given to the identification of which ecosystem services to assess. Service selection is mostly based on current state of the landscape although many landscapes are both inherently complex and rapidly changing. In this study we examine whether scenario development, a tool for dealing with uncertainties and complexities of the future, gives important insights into the selection of ecosystem services in changing landscapes. Using an agricultural landscape in South Africa we compared different sets of...

Balancing Accuracy and Meaning in Common-Pool Resource Theory
Provedor de dados: 7
Autores: Cox, Michael; School of Public and Environmental Affairs, Indiana University; Workshop in Political Theory and Policy Analysis, Indiana University; miecox@indiana.edu.
Common-pool resources are managed in complex environments that are amenable to understanding, analysis, and management at multiple levels. This paper develops a heuristic criterion to identify the costs and benefits of adopting various levels of analysis when constructing theory for common-pool resource management. It argues that there is no single optimal level for such analysis. Instead, a trade-off is posed where theories at higher levels tend to be more accurate but less meaningful than theories at lower levels.

Complex challenges demand complex solutions. By their very nature, these problems are difficult to define and are often the result of rigid social structures that effectively act as &amp;#8220;traps&amp;#8221;. However, resilience theory and the adaptive cycle can serve as a useful framework for understanding how humans may move beyond these traps and towards the social innovation that is required to address many complex problems. This paper explores the critical question of whether networks help facilitate innovations to bridge the seemingly insurmountable chasms of complex problems to create change across scales, thereby increasing resilience. The argument is made that research has not yet adequately articulated the strategic agency that must be present...

To take on the current and future challenges of global environmental change, fostering a widespread societal understanding of and engagement with the complex dynamics that characterize interacting human and natural systems is essential. Current science communication methods struggle with a number of specific challenges associated with communicating about complex systems. In this study we report on two collaborative processes, a short workshop and longer course, that aimed to harness the insights of interactive media designers and artists to overcome these challenges. The two processes resulted in 86 new interactive media concepts which were selected by the participants and organizers using set criteria and then evaluated using the same criteria by a panel...

Understanding complex social-ecological systems, and anticipating how they may respond to rapid change, requires an approach that incorporates environmental, social, economic, and policy factors, usually in a context of fragmented data availability. We employed fuzzy cognitive mapping (FCM) to integrate these factors in the assessment of future wildfire risk in the Chiquitania region, Bolivia. In this region, dealing with wildfires is becoming increasingly challenging because of reinforcing feedbacks between multiple drivers. We conducted semistructured interviews and constructed different FCMs in focus groups to understand the regional dynamics of wildfire from diverse perspectives. We used FCM modelling to evaluate possible adaptation scenarios in the...

Our intent was to provide a methodological overview of the primary data collection process in support of the other articles in this special issue. We documented and illustrated the use of a data collection and analysis suite, SenseMaker, that was designed to collect and work with narrative fragments. The approach presented adds a new and inherently mixed tool to the mixed methods toolbox. Despite its novelty and potential utility, little has been written in the academic literature on the application of SenseMaker to complex problems. To the best of our knowledge, the approach has not been used in relation to climate change or climate change adaptation and has not been presented in the mixed methods literature. We sought to contribute to filling this gap...

Autores: Trosper, Ronald L; University of British Columbia; Ronald.Trosper@ubc.ca.
The effort to combine analysis of ecosystems and social systems requires a firm theoretical basis. When humans are present in an ecosystem, their actions affect emergent structures; this paper examines forms of emergence that account for the presence of humans. Humans monitor and regulate ecosystems based on their cultural systems. Cultural systems consist of concepts linked in complicated ways that can form consistent world views, can contain inconsistencies, and may or may not accurately model the properties of a social&amp;#8211;ecological system. Consequently, human monitoring and regulating processes will differ, depending on cultural systems. Humans, as agents, change or maintain pre-existing material and cultural emergent structures.

Policy and investment decisions in highly connected, developing regions can have implications that extend beyond their initial objectives of national development and poverty reduction. Local level decisions that aim to promote trajectories toward desirable futures are often transformative, unexpectedly altering factors that are determined at higher regional levels. The converse also applies. The ability to realize desirable local futures diminishes if decision-making processes are not coordinated with other influential governance and decision levels. Providing effective support across multiple levels of decision making in a connected, transformative environment requires (a) identification and articulation of desired outcomes at the relevant levels of...

Complex systems are shaped by cross-scale interactions, nonlinear feedbacks, and uncertainty, among other factors. Transdisciplinary approaches that combine participatory and conventional methods and democratize knowledge to enable diverse inputs, including those from local, informal experts, are essential tools in understanding such systems. The metaphor of a &amp;#8220;bridge&amp;#8221; to overcome the divide between different disciplines and knowledge systems is often used to advocate for more inclusive approaches. However, there is a shortage of information and consensus on the process, methodologies, and techniques that are appropriate to achieve this.

The purpose of this paper is to report on the relationship between the parietal foramen and complexity of the human sagittal suture. Examination of 110 Japanese human skulls (males=67, females=43) with at least one parietal foramen revealed that the sagittal suture in the area of the Obelion was the simplest portion (i.e., fewest interdigitations and shortest length) of the suture (paired t-test, P&lt;0.0005), when compared to the outstretched suture length of three established sections: 1. Parietal foramen section (P); 2. Anterior to section P (B); and 3. Posterior to section P (L). Sutural complexity was also compared between individuals with unilateral foramen (n=48) and bilateral foramina (n=62) to see if there was a statistically significant...

Dynamics of fish assemblages on a continuous rocky reef and adjacent unconsolidated habitats at Fernando de Noronha Archipelago, tropical western Atlantic
Provedor de dados: 83
Autores: Medeiros,Paulo R.; Rosa,Ricardo S.; Francini-Filho,Ronaldo B.
In recent years, many studies investigated how density-dependent factors, such as shortages in microhabitat and food availability influence the structure of reef fish assemblages. Most of what is currently known, however, comes from comparisons of isolated patch reefs and from correlations between fish abundance and one or few microhabitat variables. In addition, most studies were done in the Caribbean and Indo-Pacific regions, whereas the South Atlantic region has been, to date, understudied.

Boolean logit and probit in Stata
Provedor de dados: 31
Autores: Braumoeller,   Bear F.
This paper introduces new statistical models, Boolean logit and probit, that allow researchers to model binary outcomes as the results of Boolean interactions among independent causal processes. Each process (or “causal path”) is modeled as the unobserved outcome in a standard logit or probit equation, and the dependent variable is modeled as the observed product of their Boolean interaction. Up to five causal paths can be modeled, in any combination—A and B and C produce Y, A and (B or [C and D]) produce Y, etc.

Managing Complexity in Modern Farming
Provedor de dados: 31
Autores: Kingwell,   Ross S.
Modern farming in Australia is no longer simple. Farms are large, multi-enterprise businesses underpinned by expensive capital investments, changing production technologies, volatile markets and pervasive regulation. The complexity of modern broadacre farming leads to the question: what is the nature of the relationship between farm business complexity and farm profitability? This study uses bioeconomic farm modelling and employs eight measures of complexity to examine the profitability and complexity of a wide range of broadacre farming systems in Australia. Rank order correlations between farm profitability and each measure of complexity show inconsistent relationships, although the most profitable farming systems are found to be reasonably complex on...

Membership: an Organizational View
Provedor de dados: 31
Autores: Gray,   Thomas W.
This study examines the membership structure of a large centralized cooperative from an organizational workability view. Structure is created by dividing membership organizationally, i.e., assigning different roles and tasks to different groups of members, as well as to individual members, and bringing coordination to these differentiations. The membership structure of the case cooperative was found large in number of members, highly differentiated, and well coordinated. The structuring, i.e., creating a division of labor among the membership, and the coordinating of these divisions is done in response to conditions in the membership environment.

An Emergent Economics of Ecosystem Management
Provedor de dados: 31
Autores: Hearnshaw,   Edward J.S.; Cullen,   Ross; Hughey,   Kenneth F.D.
Economics is an evolving and emerging field of study, so is the management of ecosystems. As such, this paper delineates the co-evolution of economic evaluation that reflects the various recognized ecosystem management approaches of anticipative, adaptive and capacitive ecosystem management. Each management approach is critiqued and from this theoretical analysis an emergent approach for the management of ecosystem is put forward, which accordingly suggests an alternative methodological approach for economic evaluations.

DOING POLICY IN THE LAB! OPTIONS FOR THE FUTURE USE OF MODEL-BASED POLICY ANALYSIS FOR COMPLEX DECISION-MAKING
Provedor de dados: 31
Autores: Happe,   Kathrin; Balmann,   Alfons.
For models to have an impact on policy-making, they need to be used. Exploring the relationships between policy models, model uptake and policy dynamics is the core of this article. What particular role can policy models play in the analysis and design of policies? Which factors facilitate (inhibit) the uptake of models by policy-makers? What are possible pathways to further develop modelling approaches to better meet the challenges facing agriculture today? In this paper, we address these issues from three different points of view, each of which should shed some light on the subject. The first point of view discusses models in the framework of complex adaptive systems and uncertainty. The second point of view looks at the dynamic interplay between...

Too Smart for Their Own Good! Complexity, Capacity and Credence in Trade Negotiations
Provedor de dados: 31
Autores: Kerr,   William A.
Multilateral trade negotiations are, by design, becoming increasingly complex. The current degree of complexity limits the ability to assess the effects of a potential agreement and inhibits the transparency needed to reach an agreement. Despite the considerable recent efforts at capacity building in developing countries, the additional complexity has outstripped the ability to build capacity. This article draws upon New Institutional Economics to examine the effects of complexity on trade negotiations. The conclusion is that the rational decision of many countries may be to opt for no agreement.

Integrated Assessment Modelling of Complexity in the New Zealand Farming Industry
Provedor de dados: 31
Autores: Olubode-Awosola,   Femi.
As New Zealand farming industry pursues more productivity this has implication for environment and makes land use and agricultural policy decision processes more complex for which integrated assessment modeling (IAM) can support. The purpose of this review paper is to propose means through which IAM can be improved specifically to minimize uncertainties and increase relevance, reliability, and utility of outputs of different models. Literature suggests that the general motivation for land use change is that farmers do consider the environment, but need to maintain profitability. There are handful decision support tools for land use and land policy decisions but one common feature of most of the models is that each seems suitable for only a part of the...

Effects of Endogenous Task Complexity and the Endowed Bundle on Stated Choice
Provedor de dados: 31
Autores: Hu,   Wuyang.
Conventionally, studies examining the impacts of choice complexity only consider complexity introduced exogenously from the tasks respondents face.  In the context of a stated conjoint survey, this article establishes endogenous complexity measures through decision-makers’' experience known as the endowed bundle before the survey.  Results show that complexity should not only be defined exogenously.  Endogenous complexity measures are important in determining the utility associated with an alternative and the decision of whether to participate in the market.  In addition, some of these complexity effects are nonlinear.  We also show that exogenous complexity simultaneous affects the choice consistency.

Understanding rural areas dynamics from a complex perspective. An application of Prospective Structural Analysis
Provedor de dados: 31
Autores: Ambrosio Albala,   Mateo; Delgado,   Maria del Mar.
The development of rural areas continues to be an international priority. The urgent need to fight poverty (mainly concentrated in rural areas) in developing countries, and the demand for increasing economic and social cohesion in developed countries, explain this priority on the political agendas of multilateral bodies, the EU and most other countries. When Development Economics was acknowledged as part of the social and economic theory in the 50’s, different theories and models have tried to explain the unevenness of development and the key elements or conditions that foster it. Traditional rural development programmes were characterised by the implementation of non coordinated, sectoral, horizontal and top-down policies and strategies. The lack of...

A mixed-method approach for determining the risk and complexity farmers associate with using forward contracts
Provedor de dados: 31
Autores: Jackson,   Elizabeth; Quaddus,   Mohammed; Islam,   Nazrul; Stanton,   John.
This paper reports on a model that was developed to understand the behavioural determinants surrounding farmers’ adoption of forward contracts for agricultural commodities.  Based on the Theory of Planned Behaviour and Diffusion of Innovations, 28 hypotheses within the model were written and then tested via a telephone survey that gathered 305 responses from Western Australian wool producers.  The data from the telephone survey were analysed using SPSS 14 and the Partial Least Squares approach to Structural Equation Modelling.  Most relationships within the model could be explained after rigorous quantitative analysis, however, further explanation was required to understand two final aspects of adoption behaviour: firstly, the sources of risk wool...

Inducing Strategic Bias: and its implications for Choice Modelling design
Provedor de dados: 31
Autores: Burton,   Michael P.
It has been suggested that the nature of the task within a multi-attribute multi-alternative choice experiment may be sufficiently complex to make it difficult for individuals to develop response strategies to strategically bias their answers. This experiment tested that hypothesis by setting experimental conditions that provide incentives for strategic bias. By changing design parameters one can investigate whether the strategic bias can be reduced. The answer is effectively no: under most circumstances, respondents could find a strategy that achieved significant bias in inferred preferences. The circumstances where this did not occur (involving ranking alternatives, rather than selecting a single preferred alternative) the inferred preferences reflected...

Social and Ethical Considerations of Nuclear Power Development
Provedor de dados: 31
Autores: Parkins,   John R.; Haluza-DeLay,   Randolph.
A new urgency is emerging around nuclear power development and this urgency is accentuated by the post-tsunami events at the Fukushima Daiichi nuclear power plant in Japan. This urgency extends beyond these dramatic events in Japan, however, to many other regions of the world and situations where nuclear power development is receiving renewed attention as an alternative to carbon-based energy sources. As a contribution to the growing public debate about nuclear power development, this paper offers a set of insights into the social and ethical aspects of nuclear power development by drawing from published literature in the humanities and social sciences. We offer insights into public risk perception of nuclear power at individual and national levels, the...

Beyond Economic Efficiency in Biodiversity Conservation
Provedor de dados: 31
Autores: Gatzweiler,   Franz W.; Volkmann,   Jorg.
This paper aims at explaining the importance of the democracy stance as compared to the efficiency stance in order to deal with complexity in biodiversity conservation. While the efficiency stance refers to the realm of relatively simple systems, individual rationality, and instrumental values, the complexity stance transcends these boundaries into the realm of complex systems, social rationality and intrinsic values. We argue that the task of biodiversity conservation is impossible to achieve in economically efficient ways, because (a) it is impossible to come to a (fully informed) complete account of all values, not only because it is costly but also because (b) moral values are involved which (by their nature) exclude themselves from being accounted...

Contributions of the complexity paradigm to the understanding of Cerrado's organization and dynamics
Provedor de dados: 42
Autores: MATTOS,SÉRGIO H.V.L. DE; VICENTE,LUIZ E.; PEREZ FILHO,ARCHIMEDES; PIQUEIRA,JOSÉ R.C.
ABSTRACT The Brazilian Cerrado is a vegetation mosaic composed of different physiognomies. Discussions remain open regarding the factors and processes responsible for the dynamic and spatial organization of the Cerrado - in its different physiognomies. The contributions of the complexity paradigm in this context are still less exploited, despite its great potential for explanations and predictions presented in previous diverse dynamic systems of complex behavior researches, a category in which the Cerrado can be included. This article has the intention of contributing to the construction of this new perspective, discussing - from theoretical concepts - the paradigm of complexity for the understanding of the organization and the dynamics of the Cerrado.

Bits and q-bits as versatility measures
Provedor de dados: 42
Autores: Piqueira,José R.C.
Using Shannon information theory is a common strategy to measure any kind of variability in a signal or phenomenon. Some methods were developed to adapt information entropy measures to bird song data trying to emphasize its versatility aspect. This classical approach, using the concept of bit, produces interesting results. Now, the original idea developed in this paper is to use the quantum information theory and the quantum bit (q-bit) concept in order to provide a more complete vision of the experimental results.

Approximate Entropy as a measure of complexity in sap flow temporal dynamics of two tropical tree species under water deficit
Provedor de dados: 42
Autores: Souza,Gustavo M.; Ribeiro,Rafael V.; Santos,Mauro G.; Ribeiro,Henrique L.; Oliveira,Ricardo F.
Approximate Entropy (ApEn), a model-independent statistics to quantify serial irregularities, was used to evaluate changes in sap flow temporal dynamics of two tropical species of trees subjected to water deficit. Water deficit induced a decrease in sap flow of G. ulmifolia, whereas C. legalis held stable their sap flow levels. Slight increases in time series complexity were observed in both species under drought condition. This study showed that ApEn could be used as a helpful tool to assess slight changes in temporal dynamics of physiological data, and to uncover some patterns of plant physiological responses to environmental stimuli.

Temporal dynamics of stomatal conductance of plants under water deficit: can homeostasis be improved by more complex dynamics?
Provedor de dados: 52
Autores: Souza,Gustavo Maia; Oliveira,Ricardo Ferraz de; Cardoso,Victor José Mendes.
In this study we hypothesized that chaotic or complex behavior of stomatal conductance could improve plant homeostasis after water deficit. Stomatal conductance of sunflower and sugar beet leaves was measured in plants grown either daily irrigation or under water deficit using an infrared gas analyzer. All measurements were performed under controlled environmental conditions. In order to measure a consistent time series, data were scored with time intervals of 20s during 6h. Lyapunov exponents, fractal dimensions, KS entropy and relative LZ complexity were calculated. Stomatal conductance in both irrigated and non-irrigated plants was chaotic-like. Plants under water deficit showed a trend to a more complex behaviour, mainly in sunflower that showed better...

In Brazil, scientific research is carried out mainly at universities, where professors coordinate research projects with the active participation of undergraduate and graduate students. However, there is no formal program for the teaching/learning of the scientific method. The objective of the present study was to evaluate the comprehension of the scientific method by students of health sciences who participate in scientific projects in an academic research laboratory. An observational descriptive cross-sectional study was conducted using Edgar Morin complexity as theoretical reference. In a semi-structured interview, students were asked to solve an abstract logical puzzle - TanGram. The collected data were analyzed using the hermeneutic-dialectic analysis...

The complexity-stability hypothesis in plant gas exchange under water deficit
Provedor de dados: 61
Autores: Souza,Gustavo M.; Pincus,Steven M; Monteiro,José Alberto F.
We hypothesized that more complex, i.e. irregular, temporal dynamics and a more interconnected overall network supports greater stability to gas exchange parameters (herein, CO2 net assimilation and transpiration) in plants under water deficit. To test this hypothesis two genotypes of Phaseolus vulgaris were subjected to a period of absence of irrigation, and subsequent rewatering to achieve recovery. Gas exchanges parameters were measured each 10 s during 6 h to obtain time series to evaluate complexity by Approximate Entropy (ApEn) calculations, and network connectance in each water regime. Notably, the Jalo Precoce genotype showed significantly more stability than the Guarumbé genotype under system perturbation, coincident with greater irregularity in...
