Resumen en inglés

Aquatic Functional Biodiversity: An Ecological and Evolutionary Perspective provides a general conceptual framework by some of the most prominent investigators in the field for how to link eco-evolutionary approaches with functional diversity to understand and conserve the provisioning of ecosystem services in aquatic systems. Rather than producing another methodological book, the editors and authors primarily concentrate on defining common grounds, connecting conceptual frameworks and providing examples by a more detailed discussion of a few empirical studies and projects, which illustrate key ideas and an outline of potential future directions and challenges that are expected in this interdisciplinary research field. Recent years have seen an explosion of interest in using network approaches to disentangle the relationship between biodiversity, community structure and functioning. Novel methods for model construction are being developed constantly, and modern methods allow for the inclusion of almost any type of explanatory variable that can be correlated either with biodiversity or ecosystem functioning. As a result these models have been widely used in ecology, conservation and eco-evolutionary biology. Nevertheless, there remains a considerable gap on how well these approaches are feasible to understand the mechanisms on how biodiversity constrains the provisioning of ecosystem services.

Resumen en español

Se determinaron una serie de parámetros físico-químicos en el sistema lagunar Chantuto-Panzacola, permitiendo describir sus características, como la salinidad que refleja una considerable variación temporal dando al sistema condiciones que varían de oligohalinas a mixohalinas, respectivamente. Se observó que las formas nitrogenadas más abundantes fueron los nitratos (NO- 3) y que en términos porcentuales, entre el 48.75% y el 92.32% del nitrógeno total inorgánico (NH+ 4,+NO- 3,+NO- 2), fue aportado por este compuesto. El amonio (NH+ 4) fue la segunda forma nitrogenada en abundancia, ésta aportó entre el 7.13% y el 49.45%. Los ortofosfatos (PO3- 4) presentaron las mayores concentraciones en la temporada de lluvias, disminuyendo en la temporada de secas cuando se detectaron las salinidades más altas. La Productividad Primaria Neta presenta las mayores concentraciones en las estaciones Chantuto, Panzacola, Cerritos y Campón 1, detectándose concentraciones a más del doble de lo reportado por otros autores. De lo contrario que se planteo en la hipótesis los factores físico-químicos no mostraron diferencias significativas en las estaciones de muestreo. En el Índice de Diversidad de Pigmentos (D430/D665) se observó que 71 valores de 88 son bajos, y éstos se presentan con mayor frecuencia en la época de estiaje. El Índice del Estado Trófico de Carlson (IET) ubicó a las dos épocas climáticas en b Mesotrófico (estiaje) y a Mesotrófico (lluvias); considerando que las estaciones de muestreo, ubican a las 2 lagunas de a Oligotrófico, en el caso de la Boca Barra, hasta a Eutrófico en el caso de las estaciones Chantuto y Cerritos. El TRIX ubicó al sistema en 6 - 8 con la calidad del agua pobre, altamente productiva y nivel trófico más alto. Todos los índices tróficos clasifican al sistema lagunar Chantuto-Panzacola en el mismo nivel trófico sobre todo para la época de estiaje y para las estaciones Chantuto y Cerritos.

Resumen en inglés

This book was born out of the clear need for a comprehensive resource for developing successful stream and watershed restoration plans and projects. It provides a systematic and adaptable approach for planning, prioritizing, implementing, and evaluating restoration at the regional, watershed, reach and project level. The reader will gain an understanding of stream and restoration ecology, methods for assessing watershed conditions and identifying restoration actions, different restoration techniques and their benefits and shortcomings, how to prioritize restoration actions, how to implement projects on the ground, and how to design a rigorous monitoring and evaluation program. It is organized in a stepwise fashion covering the key aspects of aquatic restoration including: assessing watershed and riverine processes and conditions, identifying restoration opportunities, choosing appropriate restoration techniques, prioritizing restoration actions, monitoring and implementation. It is intended as a guide for practitioners, an instructional manual for educators and students and a general reference for those interested in or active in the field of aquatic and restoration ecology.

Resumen en inglés

Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained. The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry.Key Features• The only single volume available to provide an in-depth discussion of the adaptations and responses of fish to environmental hypoxia. • Reviews and synthesizes the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure.• Includes discussion of the evolutionary and ecological consequences of hypoxia exposure in fish.

Resumen en inglés

The microbial community of the Nichupte-Bojorquez lagoon system located in Cancun, Mexico was evaluated using surface-water samples that were collected before and after the hurricane Wilma impacted the area on October 2005. The analysis was done using a culture-independent molecular approach involving Amplified Ribosomal DNA Restriction Analysis, and CLuster ANalysis of Sequences. A total of 61 16S ribosomal RNA genes were differentially selected and screened. The results show a bacterial profile dominated by Cytophaga-Flavobacteria/Flexibacter-Bacteroidetes group; the Bacteroidetes group in particular. The second most abundant group was assigned to the Proteobacteria group and a minor proportion of bacteria that belongs to the Cyanobacteria and Bacilli classes. Our study gives the first insight into the bacterial community adapted to this heavily polluted but occasional oligotrophic coastal lagoon; no substantial differences were, however, found.

Resumen en inglés

Plankton is an invaluable reference for environment managers, water authority ecologists, estuary and catchment management committees, coastal engineers, and students of invertebrate biology, environmental impact assessment and marine biology. This practical book provides a comprehensive introduction to the biology and ecology of plankton and describes its use as a tool for monitoring water quality. All the major freshwater and coastal phytoplankton and zooplankton groups are covered and their associated environmental issues are discussed. A chapter on best practice in sampling and monitoring explains how to design, implement and conduct meaningful phytoplankton and zooplankton monitoring programs in marine and freshwater habitats, as well as how to analyse and interpret the results for effective management decision-making. Real-life case studies demonstrate the use of plankton for identifying and monitoring water quality issues.

Resumen en español

La bahía de Chetumal (Corozal en Belice) es un extenso cuerpo de agua que sostiene gran variedad de flora y fauna en comunidades de manglar, selva, humedal y ambientes acuáticos, diversidad que se encuentra en riesgo a causa de actividades humanas. Este libro reúne relevantes estudios geológicos, biológicos, químicos, ambientales y socioeconómicos, que pueden servir de base a los tomadores de decisiones en México y Belice para lograr un mejor manejo de tan importante ecosistema.
