Risk-taking behaviour variation over time in sea bass Dicentrarchus labrax: effects of day-night alternation, fish phenotypic characteristics and selection for growth ArchiMer
Millot, Sandie; Begout, Marie-laure; Chatain, Beatrice.
Differences in bold and shy personality on sea bass Dicentrarchus labrax were investigated between a population (wild) produced from wild-brood fish and a population (selected) produced from selected-brood fish. During the experiment (112 days), fish were reared under self-feeding condition to characterize the feeding behaviour of each individual fish. Three risk-taking tests (T1, T2 and T3 of 24 h with day-night alternation) were carried out at > 1 month intervals on 180 fish of each strain in order to monitor D. labrax behaviour over time and in relation to the light:dark period. A risk-taking score was evaluated via a preference choice between a safe zone (without food) and a risky zone (potentially with food) by recording the number and the duration...

Simplified three-dimensional model provides anatomical insights in lizards' caudal autotomy as printed illustration Anais da ABC (AABC)
AMORIM,JOANA D.C.G. DE; TRAVNIK,ISADORA; SOUSA,BERNADETE M. DE.
Lizards' caudal autotomy is a complex and vastly employed antipredator mechanism, with thorough anatomic adaptations involved. Due to its diminished size and intricate structures, vertebral anatomy is hard to be clearly conveyed to students and researchers of other areas. Three-dimensional models are prodigious tools in unveiling anatomical nuances. Some of the techniques used to create them can produce irregular and complicated forms, which despite being very accurate, lack didactical uniformity and simplicity. Since both are considered fundamental characteristics for comprehension, a simplified model could be the key to improve learning. The model here presented depicts the caudal osteology of Tropidurus itambere, and was designed to be concise, in order...

Biosphere reserves are an example of social-ecological systems that combine biodiversity conservation and socioeconomic development with knowledge generation and dissemination (both scientific and local). We review lessons learned from case studies biosphere reserves in western African and France, highlighting the importance of early stakeholder engagement to build knowledge for achieving sustainable development. We discuss the evolution of the concept of biosphere reserves and its application over time in different socioeconomic and cultural settings. The diversity of stakeholders and their different needs and perceptions about nature conservation complicate implementation processes, sometimes resulting in conflicts about the objectives and zonation of...

Stakeholder participation and sustainable fisheries: an integrative framework for assessing adaptive comanagement processes Ecology and Society
Lundholm, Cecilia; Stockholm Resilience Centre, Stockholm University, Stockholm, Sweden; Centre for Teaching & Learning in the Social Sciences, Stockholm University, Stockholm, Sweden; Department of Education, Stockholm University, Stockholm, Sweden; cecilia.lundholm@cesam.su.se; Crona, Beatrice; Stockholm Resilience Centre, Stockholm University, Stockholm, Sweden; beatrice.crona@stockholmresilience.su.se; Chabay, Ilan; Institute for Advanced Sustainability Studies, Potsdam, Germany; Helmholtz Alliance on Sustainability and Social Compatibility of Future Energy Infrastructure, University of Stuttgart, Germany; ilan.chabay@gmail.com.
Adaptive comanagement (ACM) has been suggested as the way to successfully achieve sustainable environmental governance. Despite excellent research, the field still suffers from underdeveloped frameworks of causality. To address this issue, we suggest a framework that integrates the structural frame of Plummer and Fitzgibbons’ “adaptive comanagement” with the specific process characteristics of Senecah’s “Trinity of Voice.” The resulting conceptual hybrid is used to guide the comparison of two cases of stakeholder participation in fisheries management—the Swedish Co-management Initiative and the Polish Fisheries Roundtable. We examine how different components of preconditions and the...

Teaching of the Integrated Morphology International Journal of Morphology
Suazo Galdames,Iván Claudio; Cantín López,Mario; Bustos Alvarez,Ivonne Patricia; Salgado Alarcón,Guillermo Enrique.
The changes in the university curriculum have made necessary the vertical and horizontal integration of contents that are taught in morphology sciences. In this study, students of the Morphology and Human Development Module of the cohorts 2006 and 2007 participated. In 2006 the students (n=83) developed the thematic unit of locomotive apparatus in a chronologicaly and sequentially integrated way. In 2007 (n=102) this same unit was developed in a totally integrated way, in form of learning object from the macroscopic, microscopic and embryology perspectives. A theoretical instrument was designed to evaluate the content of the unit, the approaches of validity and reliability were determined (a=0.79), and then, it was applied to the 2006 and 2007 students....

TECNOLOGIA DE INFORMAÇÃO NA EDUCAÇÃO SUPERIOR: UMA ANÁLISE DO PROCESSO DE APRENDIZAGEM EM ADMINISTRAÇÃO AgEcon
Argenta, Christiane Amaral Lunkes; Brito, Mozar Jose de.
This paper, by inserting itself in the field of study that has tried to display some thoughts on the pedagogic practices brought by the new educational technologies, aimed at uncovering the meanings attributed by both students and teachers to the use of the technology of information as a mediator in the teaching-learning relation in the undergraduate Business Program of the Universidade Federal de Lavras (UFLA). The analytical effort done here shows that the technology of information as a mediator of this relation gets different meanings both for teachers and students. In the perception of those actors, the technologies of communication and information- when performing the role of mediators in the teaching-learning relation in management- stimulate the...

The brain decade in debate: I. Neurobiology of learning and memory BJMBR
Baddeley,A.; Bueno,O; Cahill,L.; Fuster,J.M.; Izquierdo,I.; McGaugh,J.L.; Morris,R.G.M.; Nadel,L.; Routtenberg,A.; Xavier,G.; Da Cunha,C..
This article is a transcription of an electronic symposium in which some active researchers were invited by the Brazilian Society for Neuroscience and Behavior (SBNeC) to discuss the last decade's advances in neurobiology of learning and memory. The way different parts of the brain are recruited during the storage of different kinds of memory (e.g., short-term vs long-term memory, declarative vs procedural memory) and even the property of these divisions were discussed. It was pointed out that the brain does not really store memories, but stores traces of information that are later used to create memories, not always expressing a completely veridical picture of the past experienced reality. To perform this process different parts of the brain act as...

Blanchard,C.; Blanchard,R.; Fellous,J.-M.; Guimarães,F.S.; Irwin,W.; LeDoux,J.E.; McGaugh,J.L.; Rosen,J.B.; Schenberg,L.C.; Volchan,E.; Da Cunha,C..
This article is a transcription of an electronic symposium in which active researchers were invited by the Brazilian Society of Neuroscience and Behavior (SBNeC) to discuss the advances of the last decade in the neurobiology of emotion. Four basic questions were debated: 1) What are the most critical issues/questions in the neurobiology of emotion? 2) What do we know for certain about brain processes involved in emotion and what is controversial? 3) What kinds of research are needed to resolve these controversial issues? 4) What is the relationship between learning, memory and emotion? The focus was on the existence of different neural systems for different emotions and the nature of the neural coding for the emotional states. Is emotion the result of the...

The brain decade in debate: VI. Sensory and motor maps: dynamics and plasticity BJMBR
Das,A.; Franca,J.G.; Gattass,R.; Kaas,J.H.; Nicolelis,M.A.L.; Timo-Iaria,C.; Vargas,C.D.; Weinberger,N.M.; Volchan,E..
This article is an edited transcription of a virtual symposium promoted by the Brazilian Society of Neuroscience and Behavior (SBNeC). Although the dynamics of sensory and motor representations have been one of the most studied features of the central nervous system, the actual mechanisms of brain plasticity that underlie the dynamic nature of sensory and motor maps are not entirely unraveled. Our discussion began with the notion that the processing of sensory information depends on many different cortical areas. Some of them are arranged topographically and others have non-topographic (analytical) properties. Besides a sensory component, every cortical area has an efferent output that can be mapped and can influence motor behavior. Although new behaviors...

The Brazilian Wine Industry: a case study on geographical proximity and innovation dynamics Rev. Econ. Sociol. Rural
Farias,Claudio Vinicius Silva; Tatsch,Ana Lúcia.
This paper aims to analyze the cooperation and learning processes in the local system of vitiviniculture production of Serra Gaúcha's region (Rio Grande do Sul, Brazil), in order to characterize the dynamics of innovation of the firms located there. In methodological terms, a non-probabilistic exploratory study has been conducted. Field research in 20 wineries as well as interviews with related organizations were carried out in order to understand which learning mechanisms support innovative strategies adopted by enterprises. Since learning processes are also the result of local interactions, it was necessary to understand whether these interactions produced cooperative links. The results showed that innovations made by the firms were basically...

THE COMPLEX DYNAMICS OF SMALLHOLDER TECHNOLOGY ADOPTION: THE CASE OF SRI IN MADAGASCAR AgEcon
Moser, Christine M.; Barrett, Christopher B..
This paper explores the dynamics of smallholder technology adoption, with particular reference to a high-yielding, low-external input rice production method in Madagascar. We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets. We then use a probit model and a symmetrically trimmed least squares estimation of a dynamic Tobit model to analyze the decisions to adopt, expand and disadopt the method. We find that seasonal liquidity constraints discourage adoption by poorer farmers. Learning effects – both from extension agents and from other farmers– exert significant influence over adoption decisions.

The influence of prior experience with artificial fruits on the ovipositioning behavior of Anastrepha fraterculus (Diptera, Tephritidae) Iheringia, Sér. Zool.
Gregório,Patrícia L. F.; Sant'Ana,Josué; Redaelli,Luiza R.; Idalgo,Thiago D. N..
The South American fruit fly, Anastrepha fraterculus (Wiedemann, 1830) (Diptera, Tephritidae), is a leading pest of Brazilian fruit crops. This study evaluated how prior experience with artificial fruits containing peach and/or guabiroba pulp influenced the ovipositing behavior of A. fraterculus. Insects 15-21 days old were exposed to four treatments: 1) experience with guabiroba, Campomanesia xanthocarpa O. Berg (Myrtaceae); 2) experience with peach, Prunus persica (L.) Batsch (Chimarrita cultivar; Rosaceae); 3) experience with both fruits; and 4) no experience (naive). Naive females and females experienced with guabiroba pulp and with both fruits (peach and guabiroba) oviposited and showed dragging and puncturing behavior on substrates containing...

The Precautionary Principle Revisited: Its Interpretations and their Conservation Consequences AgEcon
Tisdell, Clement A..
The precautionary principle was included in 1992 in the Rio Declaration on Environmental and Development and is a part of important international agreements and documents, for example, the Convention on Biological Diversity. Yet the interpretation of this principle is not straightforward as a guide for environmental policy – a variety of interpretations are possible. This paper identifies and examines various economic versions of the principle. Furthermore, it shows that different economic versions of the principle can give rise to conflicting policy recommendations for resource conservation. In addition, it demonstrates that applications of the principle do not always favour (natural) resource conservation (for example, biodiversity conservation) although...

The role of knowledge and power in climate change adaptation governance: a systematic literature review Ecology and Society
Vink, Martinus J.; Public Administration and Policy Group, Wageningen University; martinus.vink@wur.nl; Dewulf, Art; Public Administration and Policy Group, Wageningen University; art.dewulf@wur.nl; Termeer, Catrien; Public Administration and Policy Group, Wageningen University; katrien.termeer@wur.nl.
The long-term character of climate change and the high costs of adaptation measures, in combination with their uncertain effects, turn climate adaptation governance into a torturous process. We systematically review the literature on climate adaptation governance to analyze the scholarly understanding of these complexities. Building on governance literature about long-term and complex policy problems, we develop a conceptual matrix based on the dimensions knowledge and power to systematically study the peer-reviewed literature on climate adaptation governance. We find that about a quarter of the reviewed journal articles do not address the knowledge or power dimension of the governance of climate change adaptation, about half of the articles discuss either...

Towards Design For a Nutrient Trading Programme to Improve Water Quality in Lake Rotorua AgEcon
Kerr, Suzi; Lauder, Glen; Fairman, David.
This paper explores how to enhance the role for academic research (natural sciences, economics and their integration; and stakeholder management) within the development and implementation of water quality policy in New Zealand. Our focus is on the use of market based instruments and particularly nutrient trading programmes, which are one important part of the potential tool kit to address these issues. We discuss why nutrient trading might be an appropriate instrument for the Lake Rotorua catchment. We survey the existing literature and then outline the outstanding scientific, economic and governance questions that need to be addressed to design an effective trading programme. Finally we discuss how to design a process to address these questions drawing on...

Uncertainty in Integrated Assessment Models of Climate Change: Alternative Analytical Approaches AgEcon
Golub, Alexander; Narita, Daiju; Schmidt, Matthias G.W..
Uncertainty plays a key role in the economics of climate change, and the discussions surrounding its implications for climate policy are far from settled. We give an overview of the literature on uncertainty in integrated assessment models of climate change and identify some future research needs. In the paper, we pay particular attention to three different and complementary approaches that model uncertainty in association with integrated assessment models: the discrete uncertainty modeling, the most common way to incorporate uncertainty in complex climate-economy models: the real options analysis, a simplified way to identify and value flexibility: the continuous-time stochastic dynamic programming, which is computationally most challenging but necessary...

Using Numerical Dynamic Programming to Compare Passive and Active Learning in the Adaptive Management of Nutrients in Shallow Lakes AgEcon
Bond, Craig A.; Loomis, John B..
This paper illustrates the use of dual/adaptive control methods to compare passive and active adaptive management decisions in the context of an ecosystem with a threshold effect. Using discrete-time dynamic programming techniques, we model optimal phosphorus loadings under both uncertainty about natural loadings and uncertainty regarding the critical level of phosphorus concentrations beyond which nutrient recycling begins. Active management is modeled by including the anticipated value of information (or learning) in the structure of the problem, and thus the agent can perturb the system (experiment), update beliefs, and learn about the uncertain parameter. Using this formulation, we define and value optimal experimentation both ex ante and ex post. Our...

This study evaluated the possibility of decreasing defecation in a bedding area by inducing a heifer to visit a feeding station within a few minutes or immediately after standing. An experimental paddock (11.3 x 6 .8m) was made outdoors. Half of the paddock was roofed and bedded with straw to form a resting area. A feeding station was situated in the remaining area of the paddock,which was designated as the feeding area. Six Holstein heifers,the test subjects,were grouped together in the paddock. A standing detection device was developed and attached to the heifer's left hind leg. The feeding station had an antenna that identified the heifer carrying the ID-tag when it entered the station. This experiment included control period and an experimental...
