Human pressure can cause a decrease in the abundance of beach macrofauna, especially supralittoral crustaceans. In studying the life history traits of supralittoral crustaceans, human impact and beach features (e.g. beach slope, grain size, swash width) are often considered separately. Ghost crabs are widely accepted as ecological indicators of beach quality and condition since their abundance decreases at disturbed beaches; moreover, ghost crabs can respond to natural drivers. This study aims to determine factors affecting the density of the ghost crab Ocypode quadrata in the Mexican Caribbean. We studied the spatiotemporal variation of the density of ghost crabs at two urbanized and two reference beaches by counting crab burrows on all beaches during six sampling periods. Our results indicate that physical features of the beach are significantly correlated with burrow density, and burrow density varies substantially between urbanized and reference beaches. The greater variation of burrow density accounted for beach disturbance, followed by beach morphodynamic features. Basedon these results, our study confirms that the ghost crab is a relevant biological indicator species andis useful for guiding beach management criteria in the Mexican Caribbean. Our findings demonstrate that temporal replications must be included when using ghost crabs as ecological indicators.

Resumen en inglés

Establishing protected areas constitutes one of the main strategies for the conservation of marine and coastal ecosystems. Increasing risks associated with environmental change along with highly degraded coastal ecosystems encompass complex management challenges for the long-term sustainability of these landscapes. This article aims to explore the role of protected areas in past and ongoing community adaptation to the compounded effects of climatic and anthropogenic change. A literature review of published articles is conducted through systematic queries of the bibliographic database Web of Sciences, and by comparing adaptation and socialecological resilience processes within and out of coastal protected areas. Findings underscore the absence of specific studies that target these topics inside protected areas, highlighting a geographic bias towards research largely carried out in developed countries. Results also indicate the current need for management practices within protected areas to adopt more participatory, comprehensive, and flexible approaches. Protected areas not only promote the conservation and provision of ecosystem services but are also key in building coastal communities' adaptive capacity and resilience in face of future scenarios.

Resumen en inglés

Spatial distribution patterns of the ghost crab Ocypode quadrata were analysed using different approaches at one disturbed and two preserved reflective sandy beaches of the Mexican Caribbean. We used spatial correlation analysis to describe the across-shore distribution of O. quadrata and their patch dynamics by beach and sampling time. In addition, we analysed the across-shore variability of habitat extent of O. quadrata (habitat envelope) and its relation to human disturbance and beach features. The spatial structure of burrow density was consistent through time, showing a bimodal distribution with very low abundance in the mid distribution range and a discrete increment of burrows to landward. Nonetheless, the size of patches varied temporally for the three beaches. Burrow size increased from seaward to landward. The location of the first burrow and the habitat envelope varied among sampling times and beaches. The location of the first burrow is mostly mediated by the swash climate, while the habitat envelope is mainly controlled by the level of human disturbance. Despite the low number of disturbed and control beaches, our results suggest that the habitat envelope could be included in future studies when using ghost crabs as indicators of human disturbance. Polynomial models and variographic analysis proved to be useful tools to describe the across-shore distribution and patch dynamics of the ghost crab.

Resumen en inglés

The idea that Amazonian forests have been largely untouched by humans has fascinated naturalists, policy makers, the media, and natural and social scientists worldwide. For many decades, ecological studies overlooked the influence of past peoples in modern forests. However, humans arrived in the Amazon basin at least 13,000 years Before Present (BP) and populations expanded strongly around 2,500 years BP. Evidence of past human activities has been found in extensive areas previously considered pristine. Anthropogenic soils (Amazonian Dark Earths - ADE) and human-made earthworks found across the basin are examples of the landscapes domesticated by pre-Columbian peoples and evidence of large societies with considerable capacity for modifying the environment. Cultivation and management of Amazonian fora by past societies may have significantly contributed to the ecological patterns we see today. These findings stimulated an academic debate about the pristineness versus domestication of Amazonian forests. Although most scientists agree that human impacts were spatially heterogeneous across the basin, the scale of past human influences in Amazonian forests remains controversial. A more realistic and broad- scale view is required (Chapter 1). In my thesis, I integrated data from different disciplines in the social and natural sciences to generate the first broad-scale assessment of the effects of long-term human influences in modern Amazonian forests and how these legacies are maintained by local management practices. I studied the Amazon forest as a mosaic of patches domesticated to different degrees by human-nature interactions.

Resumen en español

El estudio de la historia humana permite comprender los efectos, a corto y largo plazo, de los impactos ambientales producidos por las actividades antropogénicas. En particular, la historia evolutiva de la especie humana permite identificar las adaptaciones biológicas y las estrategias que le permitieron a esta especie adaptarse al medio ambiente y transformarlo. Así, el objetivo de este tomo consiste en describir las repercusiones de la evolución biológica y cultural de la especie humana sobre el medio ambiente, para entender las consecuencias, inmediatas y a largo plazo, de la huella humana en el planeta.

Resumen en español

El impacto de las actividades humanas en el planeta compromete el futuro de nuestra propia especie. La pérdida de biodiversidad, los cambios de uso de los suelos, los ciclos de materia y energía modificados y los recursos agotados son algunos de los indicadores que nos señalan que estamos rebasando los límites de capacidad del medio natural. Además de analizar cómo es que las acciones humanas provocan cambios a gran escala, se plantea la urgente necesidad de construir una nueva relación con el entorno y entre las personas para controlar, revertir y detener los profundos impactos ecológicos que ha generado la humanidad sobre la Tierra. A través de los ciclos biogeoquímicos del planeta, la biodiversidad, el funcionamiento de los ecosistemas y otros procesos conforman las condiciones que hacen posibles la vida como la conocemos en la actualidad. La demanda casi infinita de recursos finitos no nos llevará muy lejos; por ello, es urgente modificar los patrones predominantes de consumo y apropiación de los recursos naturales para evitar un desenlace desfavorable en el futuro.

Resumen en inglés

Human behavior and action is closely related to a corresponding social and spatial environment. The nature of relations in their structures, functions, and temporal domains is characterized by a duality of contexts, an interrelatedness of the individual and local with the social and global. Causes, influences, and effects are mutual - and this at different scales. This book presents approaches that deal with interactions within and between the social and spatial realm, focusing on human behavior, land use change, and energy and infrastructure issues from an agent-based perspective.

Resumen en inglés

Land conversion, climate change and species invasions are contributing to the widespread emergence of novel ecosystems, which demand a shift in how we think about traditional approaches to conservation, restoration and environmental management. They are novel because they exist without historical precedents and are self-sustaining. Traditional approaches emphasizing native species and historical continuity are challenged by novel ecosystems that deliver critical ecosystems services or are simply immune to practical restorative efforts. Some fear that, by raising the issue of novel ecosystems, we are simply paving the way for a more laissez-faire attitude to conservation and restoration. Regardless of the range of views and perceptions about novel ecosystems, their existence is becoming ever more obvious and prevalent in today’s rapidly changing world. In this first comprehensive volume to look at the ecological, social, cultural, ethical and policy dimensions of novel ecosystems, the authors argue these altered systems are overdue for careful analysis and that we need to figure out how to intervene in them responsibly. This book brings together researchers from a range of disciplines together with practitioners and policy makers to explore the questions surrounding novel ecosystems. It includes chapters on key concepts and methodologies for deciding when and how to intervene in systems, as well as a rich collection of case studies and perspective pieces. It will be a valuable resource for researchers, managers and policy makers interested in the question of how humanity manages and restores ecosystems in a rapidly changing world.

Spatial distribution of biomass and links to reported disturbances in tropical lowland forests of southern Mexico
De Jong, Bernardus Hendricus Jozeph ;
Contenido en: Carbon Management Vol. 4, no. 6 (December 2013), p. 601-615 ISSN: 1758-3004
Resumen en: Inglés |
Resumen en inglés

The uncertainty of our understanding of the spatial variation in tropical forest biomass is still very high, due to lack of information on the effect of disturbances on carbon dynamics. Results: The spatial variation of aboveground living biomass (AGLB) in the tropical lowland forests of Mexico was high and show links with recorded human and natural disturbances. Areas with high biomass are limited to southeast Yucatan and east Chiapas. In plots with fire, land-use change and grazing, AGLB was approximately 20% lower than in undisturbed plots. Plots with forest management had higher AGLB. Conclusion: The high biomass outlier plots are an indication of the stock enhancement potential of the forests. The inventory design could be improved by collecting more quantitative information on disturbance intensity and history.

Resumen en inglés

"This book provides the first global synthesis of the biology of disturbed habitats and offers readers both the conceptual underpinnings and practical advice required to comprehend and address the unprecedented environmental challenges facing humans. Every habitat on earth has been impacted by natural disturbances such as volcanoes, earthquakes, landslides, fires, floods, and droughts. Humans have contributed many additional disturbances such as mining, urbanization, forestry, agriculture, fishing, and recreation. These anthropogenic disturbances modify and often exacerbate the effects of the natural disturbances. Together, they result in the abrupt loss of biomass or ecosystem structure and function to create denuded surfaces where novel mixtures of native and non-native microbes, plants, and animals establish, grow, and die. The Biology of Disturbed Habitats examines both natural and anthropogenic disturbances in aquatic and terrestrial habitats. It explores how nutrients and productivity are altered in the disturbed habitats, the effects of disturbance on biodiversity, and the spatial and temporal dynamics of organisms that colonize disturbed habitats. This book also addresses how to manage disturbances through appropriate conservation and restoration measures, and discusses how climate change and overpopulation now represent the most challenging disturbances at a global scale."
