Book Synopsis Jaguar (Panthera Onca) Population Dynamics, Feeding Ecology, Human Induced Mortality, and Conservation in the Varzea Floodplain Forests of Amazonia by : Emiliano E. Ramalho
Download or read book Jaguar (Panthera Onca) Population Dynamics, Feeding Ecology, Human Induced Mortality, and Conservation in the Varzea Floodplain Forests of Amazonia written by Emiliano E. Ramalho and published by . This book was released on 2012 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first chapter of this dissertation I make a thorough review of jaguar knowledge and conservation in Brazil, and apply the policy sciences approach to solving problems to understand why current jaguar conservation actions are not being effective in preventing jaguar population declines in Brazil. In the second chapter I estimate jaguar population density and survival in Mamirauá Sustainable Development Reserve using spatially explicit capture recapture models, and investigate if the co-existence of jaguars and people inside Mamirauá Reserve caused significant changes in jaguar population parameters over the course of six years of monitoring. In the third chapter I characterize the hunting of jaguars by local people in Mamirauá and Amanã Reserves, and estimate the total number of jaguars hunted in these two sites using closed population capture recaptures model and interviews. In the fourth and final chapter I investigate the feeding behavior of the jaguar in Mamirauá Reserve and compare it to other environments.

Book Synopsis Jaguars of the Northern Pantanal by : Paul Brooke
Download or read book Jaguars of the Northern Pantanal written by Paul Brooke and published by Academic Press. This book was released on 2020-06 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Jaguars of the Northern Pantanal: Panthera onca at the Meeting of the Waters details the lives and behaviors of this subpopulation of jaguars through one-of-a-kind photographs from 26 international photographers, as well as illustrations, maps, waypoints, scientific insights, field journal excerpts and personal narratives. These jaguars are the largest in the world because they eat enormous prey and these jaguars have also become habituated to human observation. The book seeks to understand how locals can coexist with these cats while benefitting financially from them through ecotourism. It provides a conceptual model to apply to other subpopulations in order to save jaguars throughout North and South America. This book focuses on jaguars in the Southern Brazil ecosystem to capture these cats up close, observing them hunting, sleeping, mating and raising their cubs. Every day in the Northern Pantanal, during the dry season, is dramatic and often revealing. The book works to uncover the intricate lives of these misunderstood animals by freezing and uncoding their behaviors. Within this glut of ecotourism, the book delves into threats and issues facing these jaguars, from poaching ranchers to soybean production, deforestation, habitat destruction, and chemical toxicity from agriculture run-off (and chemical toxicity). Jaguars of the Northern Pantanal: Panthera onca at the Meeting of the Waters is perfect for researchers and practitioners in wildlife conservation, naturalism ecotourism, and biologists.
Book Synopsis Predator-prey Relationships and Spatial Ecology of Jaguars in the Southern Pantanal, Brazil by : Sandra Maria Cintra Cavalcanti

Book excerpt: The Pantanal wetland of Brazil is an important area for the conservation of jaguars (Panthera onca) and a stronghold for the species. Although our knowledge of jaguar ecology has increased since the first field studies in the mid 1980's, a detailed study of this cryptic species remains challenging. In the following chapters, we investigated the ecology of jaguars in the southern Pantanal of Brazil. In Chapter II, we examined the foraging ecology of jaguars, documenting predation rates, patterns, and species killed. We found individual jaguars differed in the selection of their prey. There were differences in the proportion of native prey versus cattle killed by individual cats. We found that cattle (31.7%), caiman (24.4%), and peccaries (21.0%) comprised the majority of their kills. The mean predation rate on all prey for all jaguars combined was 5.1 " 5.0 (SD) days between kills. In Chapter III, we described jaguar habitat use and spatial patterns of predation in relation to vegetation and other landscape attributes. Jaguars used some habitats disproportionately to their availability both in the wet and dry seasons. Forest and shrubland habitats were generally selected by jaguars. However, the type of vegetation did not have an influence on the locations of prey killed. Contrary to expectations, jaguars did not select forested habitats nor did they avoid open fields to make kills, but killed prey in these habitats proportionately to their availability. Our results do not support earlier findings about jaguar habitat use in the southern Pantanal but illustrate the highly opportunistic nature of jaguars. In Chapter IV, we examined space use, site stability and fidelity, movement rates, and interactions of jaguars. Our results suggested a pattern of spatial avoidance among females during the wet season. Among males, home range overlap was extensive, both in the wet and dry seasons, suggesting males did not retain exclusive ranges. Our study provided insights into the dynamic land tenure system of jaguars. Future research would benefit from radiocollaring a large number of individuals and monitoring them over a longer time span to provide a better understanding of their spatial ecology and social interactions.
