Book excerpt: Protected areas (PAs) are a cornerstone of conservation policy and have been established worldwide in order to mitigate the current environmental crisis. Although PAs are usually effective at avoiding habitat conversion, their effectiveness at safeguarding local biodiversity is less clear. Furthermore, a substantial number of PAs face threats related to anthropogenic pressures that can erode the biodiversity they aim to protect. In this thesis, I use camera trap data from a mosaic of protected areas in the Brazilian Cerrado to investigate PA effectiveness and the influence of human disturbance on mammal species. Additionally, I assess the relationship between occupancy and density estimates to improve the understanding of camera trap-derived metrics in wildlife research. Overall, I surveyed 517 camera trap sites distributed across seven PAs under two contrasting types of management, totaling more than 25,000 survey days. My results revealed that PA type has a strong effect on the mammal community studied, with much higher species richness and occupancy probability in strict than in multiple-use PAs, particularly for larger and threatened mammals. I also found that succession stage of the savanna vegetation (old growth vs secondary) in a strict PA did not have a negative impact on species occupancy, and that secondary savannas supported a diverse mammal community. Despite the strong effect of PA type on the spatial distribution of mammals, I found little evidence that anthropogenic pressure influenced species" activity patterns, with few species shifting to being more nocturnal in multiple-use PAs or closer to households. Finally, my results indicated that occupancy and density estimates obtained from camera trap data tend to have a species-specific positive relationship and that under certain circumstances camera trap-derived occupancy can reflect variation in species" abundance across the landscape.

Book excerpt: Camera trapping in wildlife management and research is a growing global phenomenon. The technology is advancing very quickly, providing unique opportunities for collecting new biological knowledge. In order for fellow camera trap researchers and managers to share their knowledge and experience, the First International Camera Trapping Colloquium in Wildlife Management and Research was held in Sydney, Australia. Camera Trapping brings together papers from a selection of the presentations at the colloquium and provides a benchmark of the international developments and uses of camera traps for monitoring wildlife for research and management. Four major themes are presented: case studies demonstrating camera trapping for monitoring; the constraints and pitfalls of camera technologies; design standards and protocols for camera trapping surveys; and the identification, management and analyses of the myriad images that derive from camera trapping studies. The final chapter provides future directions for research using camera traps. Remarkable photographs are included, showing interesting, enlightening and entertaining images of animals 'doing their thing'.

Download or read book Camera trap surveillance of mammal communities in fragmented forest habitat written by David Hendler and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat fragmentation is an increasingly common problem within the field of ecosystem conservation. Through insularization, habitat loss, and edge effects, habitat fragmentation threatens biodiversity and increases the risk of local extinction. Wildlife corridors mitigate many of these threats by providing connectivity between larger fragments, or 2islands.3 Conservation efforts are often aimed at protecting these corridors, although it is not always possible to tell which corridors are in greater need of protection based on size and shape alone. Prioritizing corridors for conservation more often relies on direct examination of the species occupying them. Automated camera trap surveys are often used to collect population data, such as density and diversity, in order to assess wildlife corridor effectiveness. However, little standardization exists for examining multiple diverse taxa in a single survey. In this study, I investigated whether baiting camera traps to maximize detection frequency for carnivores and omnivores affects detection frequency for herbivores. I replicated camera trap surveys with and without bait throughout wildlife corridors and forest fragments within the Town of Red Hook, New York to examine how habitat type, bait status, and edge-to-area ratio affected estimations of species richness and relative density across 10 terrestrial vertebrate species. I found that while neither bait status nor habitat type affected observed population density of any species, corridors and non-baited traps reported higher species richness than islands and baited traps. Furthermore, I found that corridors showed higher sensitivity to seasonal changes than islands in terms of detection frequency. These results support that density and species richness are both important metrics for examining corridor health. They also highlight the importance of bait choice and seasonal effects in terms of future study design.
Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Download or read book Assessing the Effects of Tropical Land Use Change written by Samantha Zwicker and published by . This book was released on 2015 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous research shows that most mammals are reduced in fragmented forests, particularly species averse to human-modified landscapes. Since felids are elusive, sometimes nocturnal, and usually inhabit interior forest away from human activity, they can be difficult to study through in-person field observations. One effective approach to study felids is through camera trapping, where the captured images can be used to identify individuals of certain tropical felid species by their spots and bot fly warbles. To better understand the impacts of forest fragmentation on felids, the presence and distribution of both felids and their prey species were studied across a modified tropical forest gradient in the Piedras region of Madre de Dios, Peru. The goal of this study was to compare and relate species abundance and species diversity data for captured Peruvian mammals in response to land use and land cover changes (LUCC), specifically for jaguar, puma, and ocelot. Jaguar home range, distribution, and density estimates were also made using the program Camera Base. Twenty-three terrestrial mammal species were identified and assigned capture frequencies ranging from .04 to 80.7 (number of photos/1000 camera stations nights). Density of jaguars was estimated using the 8 individuals identified and data analysis in both Camera Base and DENSITY. The Jackknife Mh estimator with MMDM (mean maximum distance moved) was used to estimate jaguar density at approximately 5.05 jaguars/100 sq km. Results of this research indicate healthy populations of jaguar and ocelot, and support the theory that felids are using human modified areas for movement, habitat, and hunting. In addition, seasonally used and minimally fragmented forests in the Piedras hold abundant biodiversity and can act as corridors between core habitat and protected areas for medium and large-sized mammals. Given the demonstrated diversity and vulnerability of the Piedras region, and that it represents one of the largest unprotected and largely intact tropical rainforests in Peru, this research shows both the importance of the region in supporting robust felid populations and the urgency needed to increase the protection of the region's species and forests. The vast majority of studies looking at felids occur in protected areas like national parks, so monitoring felids in unprotected areas as a comparison is also vital.

Download or read book Movement Ecology of Afrotropical Forest Mammals written by Rafael Reyna-Hurtado and published by Springer Nature. This book was released on 2023-04-24 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings a unique perspective to animal movement studies because all studies come from African tropical environments where the great diversity, either biological and structurally (trees, shrubs, vines, epiphytes), present the animals with several options to fulfil their basic needs. These conditions have forced the evolution of unique movement patterns and ecological strategies. The book follows on our previous book “Movement Ecology of Neotropical Forest Mammals” but focuses on tropical African forests. Movement is an essential process in the life of all organisms. Animals move because they are looking for primary needs such as food, water, cover, mating and to avoid predators. Understanding the causes and consequences of animal movement is not an easy task for behavioural ecologists. Many animals are shy, move in secretive ways and are very sensible to human presence, therefore, studying the movements of mammals in tropical environments presents logistical and methodological challenges. However, researchers have recently started to be solved these challenges and exciting new information is emerging. In this book we are compiling a set of extraordinary studies where researchers have used new technology and the strongest methodological approaches to understand movement patterns in wild African forest mammals. This second book should inspire early career researchers to investigate wild mammal ́s movements in some of the most amazing forest in the world: African tropical forests.
