Evaluación del hábitat del venado cola blanca (Odocoileus virginianus mexicanus) en cuatro unidades de manejo para la conservación de la vida silvestre de la Mixteca Poblana. Colegio de Postgraduados
Díaz Hernández, Hernán.
En la Mixteca Poblana el venado cola blanca es una especie que se encuentra sujeta a una fuerte presión de uso debido a su valor económico, estético y cultural. Es por esto que las poblaciones de venado requieren de zonas donde la calidad del hábitat sea favorable y les permita asegurar su subsistencia. En este estudio se evaluaron cuatro modelos de Índice de Aptitud del Hábitat (IAH) para el venado cola blanca en la región Mixteca Poblana. Dos modelos consideraron tres variables del hábitat, con y sin factor de presión antropogénica. Los otros dos modelos consideraron solamente las variables estadísticamente significativas en una regresión logística que relacionó las variables con datos de presencia/ausencia del venado obtenidos en 92 transectos. Los...

Conocimiento tradicional y cultivo in vitro del cuatomate (Solanum glaucescens Zucc). Colegio de Postgraduados
Medina Galicia, Alfonso.
La Mixteca Baja Poblana es una región con altos índices de marginación y pobreza extrema. En ella existe una especie conocida como “cuatomate” cuya importancia reside en ser una alternativa para el desarrollo económico y social. Aunque se han desarrollado algunos trabajos sobre la especie, pocos contemplan la importancia del conocimiento campesino en su proceso de manejo, conservación y domesticación, para explicar su permanencia e importancia hasta nuestros días. También son poco conocidos aspectos importantes del cultivo tales como su reproducción, manejo y conservación. Por otra parte, la propagación de la especie por vía sexual tiene problemas porque sólo se obtienen 40% de individuos fértiles. La multiplicación asexual de la especie, por estacas, ya...

Variables del hábitat de la hormiga escamolera (Liometopum apiculatum) en el municipio de Charcas, san Luis Potosí, México. Colegio de Postgraduados
Cruz Labana, José Domingo.
En las zonas rurales de México, la hormiga "escamolera" (Liometopum apiculatum) es socioeconómicamente importante porque sus larvas, conocidas como "escamoles" se extraen de los hormigueros y son vendidos para el consumo humano. Sin embargo, la hormiga escamolera está siendo explotada de manera no sostenible y no existen estudios sobre el uso del hábitat por esta especie en el centro de México. Para identificar el uso del hábitat por la hormiga escamolera, durante la primavera-verano de 2012, se evaluaron catorce variables del hábitat en parcelas circulares de 20 m de diámetro, de 54 nidos de hormigas y de 162 parcelas seleccionadas al azar; asimismo, se estimó la densidad de nidos en sitios con tres niveles de perturbación del ecosistema. Asimismo, para...

Past, Present, and Future Old Growth in Frequent-fire Conifer Forests of the Western United States Ecology and Society
Abella, Scott R.; Public Lands Institute and School of Life Sciences, University of Nevada-Las Vegas; Scott.Abella@unlv.edu; Covington, W. Wallace; Ecological Restoration Institute; Northern Arizona University School of Forestry; wally.covington@nau.edu; Lentile, Leigh B.; Department of Forest Resources, University of Idaho; lentile@uidaho.edu; Morgan, Penelope; Department of Forest Resources, University of Idaho; pmorgan@uidaho.edu.
Old growth in the frequent-fire conifer forests of the western United States, such as those containing ponderosa pine (Pinus ponderosa), Jeffrey pine (P. jeffreyi), giant sequoia (Sequioa giganteum) and other species, has undergone major changes since Euro-American settlement. Understanding past changes and anticipating future changes under different potential management scenarios are fundamental to developing ecologically based fuel reduction or ecological restoration treatments. Some of the many changes that have occurred in these forests include shifts from historically frequent surface fire to no fire or to stand-replacing fire regimes, increases in tree density, increased abundance of fire-intolerant trees, decreases in understory productivity,...

This paper contends that natural resource management (NRM) issues are, by their very nature, complex and that both scientists and managers in this broad field will benefit from a theoretical understanding of complex systems. It starts off by presenting the core features of a view of complexity that not only deals with the limits to our understanding, but also points toward a responsible and motivating position. Everything we do involves explicit or implicit modeling, and as we can never have comprehensive access to any complex system, we need to be aware both of what we leave out as we model and of the implications of the choice of our modeling framework. One vantage point is never sufficient, as complexity necessarily implies that multiple (independent)...

On an increasingly populated planet, with decreasing biodiversity and limited new opportunities to tap unexploited natural resources, there is a clear need to adjust aspects of marine management and governance. Although sectarian management has succeeded in addressing and managing some important threats to marine ecosystems, unintended consequences are often associated with overlooking nonlinear interactions and cumulative impacts that increase the risk of surprises in social-ecological systems. In this paper, we begin to untangle science-governance-society (SGS) interdependencies in marine systems by considering how to recognize the risk of surprise in social and ecological dynamics. Equally important is drawing attention to our state of preparedness,...

Scale Mismatches in Social-Ecological Systems: Causes, Consequences, and Solutions Ecology and Society
Cumming, Graeme S; University of Florida; graeme@botzoo.uct.ac.za; Cumming, David H. M.; University of Zimbabwe; cumming@icon.co.zw; Redman, Charles L; Arizona State University; charles.redman@asu.edu.
Scale is a concept that transcends disciplinary boundaries. In ecology and geography, scale is usually defined in terms of spatial and temporal dimensions. Sociological scale also incorporates space and time, but adds ideas about representation and organization. Although spatial and temporal location determine the context for social and ecological dynamics, social-ecological interactions can create dynamic feedback loops in which humans both influence and are influenced by ecosystem processes. We hypothesize that many of the problems encountered by societies in managing natural resources arise because of a mismatch between the scale of management and the scale(s) of the ecological processes being managed. We use examples from southern Africa and the...

Past and future landscape dynamics in pasture-woodlands of the Swiss Jura Mountains under climate change Ecology and Society
Silvopastoral systems are traditional components of the landscape in the Swiss Jura Mountains, and are promising approaches for the sustainable management of mountain areas worldwide. Due to complex vegetation dynamics, pasture-woodlands are very vulnerable to the currently occurring land use and climate changes. Therefore, management requires integrative long-term predictions of successional trends. We present a refined version of the spatially explicit, dynamic simulation model WoodPaM with improved climate sensitivity of simulated vegetation. We investigate pasture-woodland dynamics by applying an innovative combination of retrospective simulations starting in the Middle Ages with prospective simulations following two climate change scenarios. The...

A Participatory Modeling Process to Capture Indigenous Ways of Adaptability to Uncertainty: Outputs From an Experiment in West African Drylands Ecology and Society
d'Aquino, Patrick; CIRAD; daquino@cirad.fr; Bah, Alassane; UMISCO ESP UCAD Dakar; alassane.bah@gmail.com.
Over the centuries, local communities have shaped atypical rules to deal with the uncertainty of their environment. They have developed complex prototypes for flexible overlapping institutions and arrangements to adapt their rules and uses to their uncertain environment. Today, this indigenous way of flexibly institutionalizing access rules could provide blueprints for dealing with uncertainty issues resulting from global change as well as designing practical guidelines for implementing resilient management. However, transforming indigenous skills for developing institutional flexibility into operational management rules that are appropriate in the current environmental and socioeconomic context is a huge challenge. However, communities could easily...

Scale Mismatches in Management of Urban Landscapes Ecology and Society
Elmqvist, Thomas; Stockholm University, Department of Systems Ecology; thomase@ecology.su.se; Angelstam, Per; School of Forest Engineers, Swedish University of Agricultural Sciences; per.angelstam@smsk.slu.se; Alfsen-Norodom, Christine; Columbia University/UNESCO Joint Program on Biosphere and Society; alfsen-norodom@un.org.
Urban landscapes constitute the future environment for most of the world’s human population. An increased understanding of the urbanization process and of the effects of urbanization at multiple scales is, therefore, key to ensuring human well-being. In many conventional natural resource management regimes, incomplete knowledge of ecosystem dynamics and institutional constraints often leads to institutional management frameworks that do not match the scale of ecological patterns and processes. In this paper, we argue that scale mismatches are particularly pronounced in urban landscapes. Urban green spaces provide numerous important ecosystem services to urban citizens, and the management of these urban green spaces, including recognition of...

Organics, trust, and credibility: a management and media research perspective Ecology and Society
Rittenhofer, Iris; School of Business and Social Sciences, Aarhus University; iri@bcom.au.dk; Povlsen, Karen Klitgaard; Department of Aesthetics and Communication, Aarhus University; karenklitgaard@hum.au.dk.
Our purpose was to qualify the relations between trust, credibility, and the field of organics by way of creating a dialogue between two independent Organic Research, Development and Demonstration Programme “MultiTrust” subprojects. Both projects explore the explanatory value of trust and credibility for the success of organic labels in the fields of management research and media research. Our key objectives were to critically scrutinize the trust and credibility constructs applied in each of these two fields, to reflect on their explanatory value in the performance of organics from both a management and media perspective, and to set out an agenda for future interdisciplinary research. We conclude that relations between organic...

Despite their well-known role as pests, termites also provide essential ecosystem services. In this paper, we undertook a comprehensive review of studies on human–termite interactions and farmers’ indigenous knowledge across Sub-Saharan Africa in an effort to build coherent principles for termite management. The review revealed that local communities have comprehensive indigenous knowledge of termite ecology and taxonomy, and apply various indigenous control practices. Many communities also have elaborate knowledge of the nutritional and medicinal value of termites and mushrooms associated with termite nests. Children and women also widely consume termite mound soil for nutritional or other benefits encouraged by indigenous belief...
