Life histories characterized by long life spans, delayed age at first reproduction, iteroparity, small litter sizes, high maternal investment in offspring, and long generation times expose many iconic large mammals to elevated risks of extinction. Among these risks are habitat loss, habitat degradation, escalating threats of climate change, illegal killing, disease, or inbreeding. Comprehending the threats faced by large mammals, and exploring how to counter those challenges effectively, are important steps toward conserving wild populations now and in the near future.

Available in PDF, EPUB and Kindle. Book excerpt: Large Carnivores and the Conservation of Biodiversity brings together more than thirty leading scientists and conservation practitioners to consider a key question in environmental conservation: Is the conservation of large carnivores in ecosystems that evolved with their presence equivalent to the conservation of biological diversity within those systems? Building their discussions from empirical, long-term data sets, contributors including James A. Estes, David S. Maehr, Tim McClanahan, Andrès J. Novaro, John Terborgh, and Rosie Woodroffe explore a variety of issues surrounding the link between predation and biodiversity: What is the evidence for or against the link? Is it stronger in marine systems? What are the implications for conservation strategies? Large Carnivores and the Conservation of Biodiversity is the first detailed, broad-scale examination of the empirical evidence regarding the role of large carnivores in biodiversity conservation in both marine and terrestrial ecosystems. It contributes to a much more precise and global understanding of when, where, and whether protecting and restoring top predators will directly contribute to the conservation of biodiversity. Everyone concerned with ecology, biodiversity, or large carnivores will find this volume a unique and thought-provoking analysis and synthesis.

Available in PDF, EPUB and Kindle. Book excerpt: Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition, provides a synthesis of model-based approaches for analyzing presence-absence data, allowing for imperfect detection. Beginning from the relatively simple case of estimating the proportion of area or sampling units occupied at the time of surveying, the authors describe a wide variety of extensions that have been developed since the early 2000s. This provides an improved insight about species and community ecology, including, detection heterogeneity; correlated detections; spatial autocorrelation; multiple states or classes of occupancy; changes in occupancy over time; species co-occurrence; community-level modeling, and more. Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition has been greatly expanded and detail is provided regarding the estimation methods and examples of their application are given. Important study design recommendations are also covered to give a well rounded view of modeling. Provides authoritative insights into the latest in occupancy modeling Examines the latest methods in analyzing detection/no detection data surveys Addresses critical issues of imperfect detectability and its effects on species occurrence estimation Discusses important study design considerations such as defining sample units, sample size determination and optimal effort allocation

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation assesses aspects of biodiversity conservation in East Africa from three angles: 1) protected area representation and effectiveness, 2) wildlife corridors, and 3) large mammal sensitivity to humans in savanna ecosystems. I first consider protected area representation and effectiveness across East Africa (Burundi, Kenya, Rwanda, Tanzania and Uganda – 1,722,114 km2) (Riggio et al. under review; Chapter 1). Protected areas are the cornerstone of in situ conservation and their effective management is critical for maintaining biodiversity in the long term. East Africa contains a network of 1,776 protected areas (including 186 protected areas with IUCN management categories I through IV) covering more than 27% of its terrestrial area. However, many of these protected areas were established before the advent of modern conservation biology, and several are now threatened by land conversion fueled by rapid human population growth. Here I document the extent to which East African protected areas encompass ecoregions and endemic terrestrial vertebrate taxa and, using new land conversion data derived from high spatial resolution satellite images, I assess how they have been encroached upon by agriculture and other land use. I find that East African protected areas cover most ecoregions well (>10% threshold of ecoregion representativeness set by the Convention on Biological Diversity’s Aichi Target 11), some very well (>90% - Rwenzori-Virunga montane moorlands and East African montane moorlands), but Masai xeric grasslands and shrublands, Somali Acacia-Commiphora bushlands and thickets, and Southern Swahili coastal forests and woodlands are poorly represented. While protected areas cover the geographic distribution of most East African endemic and near-endemic terrestrial vertebrate species, they cover less than 10% of the distribution of 47 endemic species (16% of the 303 endemic species). Encouragingly, East African protected areas are largely unconverted to human use, with only 6.8% of their total area experiencing land conversion (1.6% for strict protected areas). I then aim to assess the current state of wildlife corridors across Tanzania (Riggio & Caro 2017; Chapter 3) using Wami-Mbiki Wildlife Management Area as a test case (Riggio et al. 2018; Chapter 2). Wildlife corridors can help maintain landscape connectivity but novel methods must be developed to assess regional structural connectivity quickly and cheaply so as to determine where expensive and time-consuming surveys of functional connectivity should occur. I use least-cost methods, the most accurate and up-to-date land conversion dataset for East Africa, and interview data on wildlife corridors, to develop a single, consistent methodology to systematically assess wildlife corridors at a national scale using Tanzania as a case study. My research aims to answer the following questions; (i) which corridors may still remain open (i.e. structurally connected) at a national scale, (ii) which have been potentially severed by anthropogenic land conversion (e.g., agriculture and settlements), (iii) where are other remaining potential wildlife corridors located, and (iv) which protected areas with lower forms of protection (e.g., Forest Reserves and Wildlife Management Areas) may act as stepping-stones linking more than one National Park and/or Game Reserve. I identify a total of 52 structural connections between protected areas that are potentially open to wildlife movement, and in so doing add 23 to those initially identified by other methods in Tanzanian Government reports. I find that the vast majority of corridors noted in earlier reports as “likely to be severed” have actually not been cut structurally (21 of 24). Nonetheless, nearly a sixth of all the wildlife corridors identified in Tanzania in 2009 have potentially been separated by land conversion, and a third now pass across lands likely to be converted to human use in the near future. My study uncovers two reserves with lower forms of protection (Uvinza Forest Reserve in the west and Wami-Mbiki Wildlife Management Area in the east) that act as apparently crucial stepping-stones between National Parks and/or Game Reserves and therefore require far more serious conservation support. Methods used in this study are readily applicable to other nations lacking detailed data on wildlife movements and plagued by inaccurate land cover datasets. My results are the first step in identifying wildlife corridors at a regional scale and provide a springboard for ground-based follow-up conservation. Finally, I evaluate the sensitivity of the larger mammals of savanna Africa to humans (Riggio et al. 2018b; Chapter 4). Habitat loss and overexploitation are driving differential declines in vertebrate taxa but variation in responses means it is often difficult to determine where to place conservation effort. Here I present an easy-to-use method to rank the relative sensitivities of the larger mammals of savanna Africa to human activities in order to prioritize conservation activities. I first make coarse predictions about susceptibility based on species’ intrinsic ecological traits. Next I determine actual presence of these species using transect surveys within the heavily impacted Wami-Mbiki Wildlife Management Area in Tanzania, by conducting interviews outside this protected area, and monitoring changes in populations within both of these zones. Finally I use these combined data to derive a sensitivity measure than we compared to prior predictions about the susceptibility. My empirical measure of sensitivity to humans is positively correlated with species’ body mass, and home range size. The empirical data allow me to categorize these species into those that are very sensitive to humans (species in danger), sensitive to humans (human avoiders), moderately common species (human adapters), and those that are positively impacted by people (human exploiters). Conservation efforts aimed at human avoiders and species in danger are likely to have disproportionate payoffs in protecting larger mammal assemblages in Africa as these more sensitive species likely act as focal species (sensu Lambeck 1997) for management efforts. My measures combine easy-to-conduct transect data with interview data, and evaluate temporal changes to reach conclusions about how sensitive large mammals are to humans. These methods can be applied in other regions where studies are beginning to examine wildlife declines outside protected areas. Literature Cited: Riggio, J., Hijmans, R., Jacobson, A., and Caro, T.

Available in PDF, EPUB and Kindle. Book excerpt: This is an updated version of the best selling first edition, Ecological Census Techniques, with updating, some new chapters and authors. Almost all ecological and conservation work involves carrying out a census or survey. This practically focussed book describes how to plan a census, the practical details and shows with worked examples how to analyse the results. The first three chapters describe planning, sampling and the basic theory necessary for carrying out a census. In the subsequent chapters international experts describe the appropriate methods for counting plants, insects, fish, amphibians, reptiles, mammals and birds. As many censuses also relate the results to environmental variability, there is a chapter explaining the main methods. Finally, there is a list of the most common mistakes encountered when carrying out a census.

Book excerpt: The publication of Reintroduction Biology of Australian and New Zealand Fauna nearly 20 years ago introduced the new science of ‘reintroduction biology’. Since then, there have been vast changes in our understanding of the process of reintroductions and other conservation-driven translocations, and corresponding changes in regulatory frameworks governing translocations. Advances in Reintroduction Biology of Australian and New Zealand Fauna is a timely review of our understanding of translocation from an Australasian perspective, ensuring translocation becomes an increasingly effective conservation management strategy in the future. Written by experts, including reintroduction practitioners, researchers and policy makers, the book includes extensive practical advice and example case studies, identifies emerging themes and suggests future directions. Topics include: key questions in reintroduction biology; population establishment; prey naivety; disease management; dispersal; the roles of trials and experiments; modelling projections; assisted colonisation; population interchange; genetic diversity; disease management; metapopulation dynamics; reintroduced species as ecological engineers; the contributions of sanctuary networks and zoos; and extensive insights from reintroduction programs. This book is aimed at conservation practitioners and researchers, as well as conservation management agencies and NGOs. Although it is based on Australasian examples, it will be of interest globally due to synergies with reintroduction programs throughout the world.

This book was released on 2009-05-11 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.
