Book excerpt: As global biodiversity loss continues to accelerate at an unprecedented rate, the maintenance of diversity at regional and local scales is a key target in restoration and land management. In order to protect these threatened ecosystems, it is fundamental to understand the patterns and underlying processes that shape this biodiversity. For example, we know that biodiversity is not distributed equally across the landscape, but rather, many species exist in small patches or diversity 'hotspots' distributed across larger ecosystems. These patches can contain only a few species each, but high variation between them can add up to a great deal of diversity at the landscape level. Species diversity and the patterns of species distribution are likely to be sensitive to managed disturbance regimes, such as livestock grazing, and temporal variability in environmental conditions, such as the timing and amount of rainfall within a given season. In this dissertation, I investigate how these multiple layers of spatial and temporal heterogeneity interact to produce patterns of biodiversity in California vernal pools, or seasonally flooded depressions within grasslands. Vernal pools are among the Californian bioregion's most important and critically threatened reservoirs of endemic plant diversity. In Chapter 1, I examine how long-term livestock grazing affects the distribution of plant diversity within and between vernal pools, and whether grazing-related changes in species distribution at the local scale may lead to changes in diversity at the landscape scale. In Chapter 2, I aim to understand whether the reintroduction of livestock to vernal pools that have been under long-term grazing exclusion has similar effects as continuous grazing, and also explore the potential grazing-related mechanisms driving these community changes. In Chapter 3, I aim to identify the aspects of vernal pool hydrology that are most biologically relevant for sensitive plant and animal taxa, specifically temporal variation in pool water depth, and determine which sampling methods best capture this variability. Together, the findings of this dissertation help to increase our understanding of how patterns of biodiversity respond to disturbance and environmental variation, and provide insight into the management of these highly heterogeneous landscapes.

Available in PDF, EPUB and Kindle. Book excerpt: Vernal pools are ephemeral wetlands that exist in local geographic depressions with relatively impermeable substrates. Vernal pools are typically filled with water primarily from direct precipitation in the winter and spring months and are dried because of evaporation and seepage in the summer and fall months. The unusual hydrology of vernal pools has led to unique species compositions within the pool as few plant species can tolerate the hydrologic extremes found in vernal pools. Of the roughly 100 different species of plants often found in California vernal pools, 90% are native and 55% are endemic to California. Land use changes and climate change threaten vernal pools. Understanding the impacts of climate change to vernal pool hydrology and the plant community will be important for managing these sensitive ecosystems. Previous vernal pool modeling efforts have been limited to hydrologic quantification while qualitatively discussing the impacts to vegetation. Creating coupled hydrologic and vegetative models is critical to quantitatively understanding impacts to vernal pool vegetation. A mass balance hydrologic model was created that uses precipitation and temperature as climate inputs and generates a pool stage time-series as an output. Three vegetation models were created from an existing plant community classification system. The vegetation models use the pool stage time-series from the hydrologic model to estimate a vegetative community distribution within the pool. Bias-corrected data from three global climate models (GCM) were used as climate inputs for coupled models of vernal pool hydrology and plant community distribution. Climate data from the years 1991-2000 and 2091-2100 for the A2 and B1 emission scenarios from each GCM were used. Changes in plant communities were compared between the 1991-2000 and 2091-2100 time segments for each emission scenario. The hydrologic model results indicate that predicted average annual maximum depth in 2091-2100 did not significantly differ from current conditions under either the A2 or B1 emission scenario. Hydroperiod was predicted to significantly decrease under the A2 scenario, but not under the B1 scenario. Vegetative model results indicate that the pool area containing plant communities associated with vernal pool specialists decreased under the A2 and B1 emission scenarios with the decrease more pronounced under the A2 scenario. Overall, the study indicates that creating coupled hydrologic and vegetation models for vernal pools provide insight on potential impacts of hydrology and climate change on vernal pool plant communities, but models of sensitive hydrologic systems like vernal pools require climate data with high spatial and temporal resolution.

Available in PDF, EPUB and Kindle. Book excerpt: Ponds are an exceptional freshwater resource around the world and represent thirty percent of the global surface area of standing water. Furthermore, the millions of ponds which exist exhibit a particularly high biodiversity and have a high potential for ecosystem functions and services. Despite these impressive features, ponds face many threats from a variety of human activities and receive little or no protection under European and national legislation. Consequently, there is an urgent need to protect, consolidate and increase the pond resource in Europe. In order to achieve these objectives, the European Pond Conservation Network (EPCN) was launched 2004 in Geneva. Its aim is to promote the awareness, understanding and conservation of these small water bodies in the European landscape. This volume of “Developments in Hydrobiology” presents a selection of 31 papers presented during EPCN conferences held in 2006 in France (Toulouse) and in 2008 in Spain (Valencia). They represent a diverse collection of themes from across the continent and North Africa and present new and original insights into topics as wide ranging as pond biodiversity; human disturbance; landscape ecology; ecological assessment and monitoring; practical management measures; ecological restoration; hydrology and climate change; invasive species and threatened species.

Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.
