A groundbreaking review of the seldom-studied semi-aquatic freshwater mammals, covering biology, behavior, and conservation. Semi-aquatic mammals are some of the rarest and most endangered mammals on earth. What binds them together in the minds of biologists, despite their diverse taxa and body forms, are evolutionary traits that allow them to succeed in two worlds—spending some time on land and some in the water. Semi-aquatic Mammals fills a crucial void in the literature by highlighting the important ecological roles and curious biology of these remarkable animals. In this unique book, wildlife ecologist Glynnis A. Hood presents the first comprehensive examination of a global suite of 140 freshwater semi-aquatic mammals. Each one has overcome the distinct ecological challenges of thriving in both aquatic and terrestrial habitats as part of everyday life. Covering millions of years, Hood's exploration begins with the extinct otter-like Buxolestes and extends to consider the geographical, physical, behavioral, and reproductive traits of its present-day counterparts. Hood explains how semi-aquatic mammals are able to navigate a viscous environment with almost no resistance to heat loss, reveals how they maintain the physical skills necessary to avoid predation and counter a more thermally changeable environment, and describes the array of adaptations that facilitate success in their multifaceted habitats. She also addresses specific conservation challenges faced by these mammals. Her analysis takes readers to the haunts of intriguing semi-aquatic mammals from around the world, • introducing the "paradoxical platypus," an Australian egg-laying monotreme that detects prey through electroreception • venturing into the swamps and mangroves of Southeast Asia, where fishing cats wave their paws above the water's surface to lure prey • trawling the streams and lakes of South America, where the female water opossum uses its backward-facing pouch to keep her babies warm during deep dives • spending time with species that engineer freshwater habitats into more productive and complex systems, including North American beavers and Africa's common hippopotamus Featuring award-winning artist Meaghan Brierley's stunning illustrations throughout, Semi-aquatic Mammals is an unparalleled reference on some of the world's most tenacious and fascinating mammals.

Mammals in freshwater aquatic systems play important roles as ecosystem engineers, trophic transfer agents, and apex predators, thus acting as indicators of freshwater ecosystem function. Watersheds inhabited by semi-aquatic mammals have increased links between adjacent terrestrial and aquatic ecosystems compared to watersheds where they are not present. Semiaquatic mammals not only exert top-down influences on streams, but are affected by bottom-up forces from the riparian system itself. The goal of this study was to identify variables that correlate with the presence of beaver (Castor canadensis), muskrat (Ondatra zibethicus ), mink (Neovison vison), and river otter ( Lontra canadensis), including their interactions, resulting in a better understanding of the areas where these semi-aquatic mammals occur and their effects on the riparian system. The objectives of this study were (1) to identify variables related to the probability of detection, initial occupancy, colonization, and extinction of the 4 semi-aquatic mammals in southern Illinois; and (2) to test if the reintroduction of river otter has changed stream food webs. To address my first objective, I sampled 120 bridge sites in 2 periods (winter: Jan-Feb; and spring: Mar-Apr) during 2012–2014 in 11 major watersheds in the southern third of Illinois (44,526 km2) to estimate multi-season occupancy. Each survey unit was a 400-m stream segment visited twice by 2 observers for a total of 4 observations per site per period. Observers recorded all mammal signs found, including sign species and type. Sites were Intensive Basin Survey Sites sampled by Illinois Department of Natural Resources (IDNR) and Illinois Environmental Protection Agency (IEPA), allowing data collected by the state to be available for explanatory variables for mammal occupancy. Data collected by the Illinois Natural History Survey (INHS) also were available for a subset of sites. I collected local- and landscape-scale habitat and weather variables for each site. I developed hypotheses regarding occupancy of sites based on land-cover, human disturbance, and stream attributes for each species. I developed additional hypotheses regarding prey availability and water quality for river otter and mink. Sites used in each analysis were dependent on data available to address the hypotheses of interest. My results indicate that semi-aquatic mammals in Illinois were affected by a riparian habitat, water availability, and stream community variables at both the landscape and local scale. I found high occupancy of mink, beaver, and muskrat across the entire landscape of southern Illinois, and my results suggest that the geographic range of river otter continues to expand. Relationships of occupancy of these semi-aquatic mammals to measurements of urban areas and human disturbance were not consistent across all species. Mink and river otter occupancy were both predicted by aspects of prey availability, indicating the importance of predator-prey relationships in occupancy dynamics of riparian predators. Hypotheses regarding predator pressure and changes in environmental variables were used to test the effects of river otter reintroduction on stream communities. For this objective, I used structural equation models. I compared fish and macroinvertebrate communities from before (1982-1995) and after (2005-2013) reintroduction of river otter, which occurred in 1994–1996. Fish and macroinvertebrate community data for 35 sites located throughout 6 major watersheds in southern Illinois (25,550 km2) were obtained from state agencies. Changes in stream communities were evaluated using 4 metrics (species richness, species dominance, skewness in size distribution of prey, and proportion of individuals in the size class preferred by river otter). Neither the inclusion of river otter site use nor change in stream quality, measured by change in % forest, improved models over the simple model which only included fish and macroinvertebrate communities. Overall, I found no evidence that river otter presence or change in forest cover affected stream fish and macroinvertebrate communities. (Abstract shortened by ProQuest.)
