Book excerpt: Northern elephant seals (Mirounga angustirostris) established a breeding population at Point Reyes National Seashore (PORE) in 1981 and since then the colony has grown steadily (Allen et al. 1989). Currently, elephant seals breed at numerous sites within PORE, with four primary sites located at Drake's Beach (DB), Point Reyes Headland (PRH), South Beach (SB), and Chimney Rock Loop (CRL). PORE began to monitor the elephant seal population to contribute to the understanding of population changes and management needs, and to develop research, interpretation and enforcement strategies. A pinniped monitoring protocol was developed in 2009 and includes objectives for monitoring elephant seals to determine trends population growth and productivity.

Book excerpt: After having been extirpated to near extinction at the turn of the century, northern elephant seals (Mirounga angustirostris) have re-established breeding colonies on isolated beaches and offshore islands along the California coast since the 1950's (Stewart et al. 1994). In 1981, the first northern elephant seal birth was recorded at an isolated pocket beach at the Point Reyes National Seashore (PORE; Allen et al. 1989).

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The King Range colony is the northernmost successful and expanding breeding site for northern elephant seals (Mirounga angustirostris). To evaluate the composition and growth of this colony, I conducted systematic surveys recording counts, age classes, births, and resighting seals with individually identifiable flipper tags. The timing of life-history events (breeding, molting, and resting) of all elephant seal sex and age groups at the King Range was consistent with observations at other colonies. Colony counts during breeding and molting have increased steadily over the 4-year study period (2018-2021), and pup production has increased by 87% since the first year of monitoring. The main driver of colony growth was juvenile elephant seals dispersing from colonies in central California, as revealed by the majority of tag resights being of juveniles from Point Reyes. Juvenile seasonal haul out behavior differed with a higher percentage of ‘new’ juveniles seen in the fall than in the spring and higher variability in seasonal arrival date, tenure, and number of visits in the fall resting haul out than during the spring molt. This difference may be due to the extreme physiological demands on elephant seals during their spring molt, which is absent during the fall. This growing northern elephant seal colony will likely become a seed colony for further northern dispersal as this species continues to be impacted by global climate change. By documenting juvenile dispersal and colony growth, I provide information to managers and the public for use in preparing and managing conflicts that might arise with the predicted expansion and redistribution of this species.

Available in PDF, EPUB and Kindle. Book excerpt: The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them.

Available in PDF, EPUB and Kindle. Book excerpt: El Niño is a meteorological and oceanographic phenomenon, which occurs at irregular intervals in the eastern tropical Pacific. Its most obvious characteristic is the warming of surface waters, which causes enormous disturbances of the marine environment. A severe Niño may also affect continental systems worldwide. This book gathers in a comprehensive way the information available on the effects of the exceptionally strong 1982-83 Niño on a group of marine mammals, the pinnipeds. It presents an analysis of the effects of environmental stress on the populations of top predators. Data and interpretations are based on a most unusual collection of long-term studies of pinniped population dynamics, behavior and ecology which spanned the El Niño event. The responses of pinniped populations to the El Niño disturbance of the marine ecosystem also has important implications for the management and conservation of marine mammal populations.

Book excerpt: Pinnipeds are a fascinating group of marine mammals that play a crucial role as apex predators and sentinels of the functioning and health of marine ecosystems. They are found in the most extreme environments from the Polar regions to the tropics. Pinnipeds are comprised of about 34 species, and of those at least 25% live permanently in tropical zones. This book reviews and updates current research on the biology, marine ecology, bio-monitoring, and conservation of tropical pinniped populations, including their behavior, anthropogenic stressors, and health. It also looks at challenges to be faced for the conservation of tropical pinnipeds, many of which are threatened species.

This book was released on 2016-07-05 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.

Available in PDF, EPUB and Kindle. Book excerpt: With more than 1,400 species, bats are an incredibly diverse and successful group of mammals that can serve as model systems for many unique evolutionary adaptations. Flight has allowed them to master the sky, while echolocation enables them to navigate in the dark. Being small, secretive, nocturnal creatures has made bats a challenge to study, but over the past 50 years, innovative research has made it possible to dispel some of the mystery and myth surrounding them to give us a better understanding of the role these animals play in the ecosystem. The structure of the book is based on several broad themes across the biological sciences, including the evolution of bats, their ecology and behavior, and conservation of biodiversity. Within these themes are more specific topics on important aspects of bat research, such as morphology, molecular biology, echolocation, taxonomy, systematics, threats to bats, social structure, reproduction, movements, and feeding strategies. Given its scope, the book will appeal to the wider scientific community, environmental organizations, and government policymakers who are interested in the interdisciplinary aspects of biology and nature.
