Book Description
The Tropics are home to the greatest biodiversity in the world, but tropical species are at risk due to anthropogenic activities, mainly land use change, habitat loss, invasive species, and pathogens. Over the past 20 years, the avian malaria and related parasites (Order: Haemosporida) systems have received increased attention in the tropical regions from a diverse array of research perspectives. However, to date no attempts have been made to synthesize the available information and to propose new lines of research. This book provides such a synthesis by not only focusing on the antagonistic interactions, but also by providing conceptual chapters on topics going from avian haemosporidians life cycles and study techniques, to chapters addressing current concepts on ecology and evolution. For example, a chapter synthesizing basic biogeography and ecological niche model concepts is presented, followed by one on the island biogeography of avian haemosporidians. Accordingly, researchers and professionals interested in these antagonistic interaction systems will find both an overview of the field with special emphasis on the tropics, and access to the necessary conceptual framework for various topics in ecology, evolution and systematics. Given its conceptual perspective, the book will appeal not only to readers interested in avian haemosporidians, but also to those more generally interested in the ecology, evolution and systematics of host-parasite interactions.

Book Description
Marshall Lairds Avian Malaria In The Asian Tropical Subregion will be only the second book to be devoted solely to the species of Plasmodium parasitising birds. The first, Redginal Hewitts Bird Malaria, Baltimore, The Johns Hopkins Press, appeared in 1940, and was largely devoted to relevant laboratory investigations. A number of additional species of these parasites had been described by 1966, when the late Professor Cyril Garnhams classic Malaria Parasites And Other Haemosporidia was published (Blackwell, Oxford), eight of the fifty chapters of which concerned the true avian malaria parasites and have since remained the standard reference. The present book is particularly timely in bringing the whole subject up to date for a huge tropical part of the globe, which is at the same time at the heart of a widespread network of migratory bird species; many of which it demonstrates to carry important species of plasmodia in their blood. The authors findings, which demonstrate the presence of most of the valid species of bird malaria parasites and a single highly distinct new one in the Asian Tropical Subregion and its eastern and western borders, will serve as a source for the sure identification of these; illustrated as it is by high quality photomicrographs from many of the 536 individual birds of 180 species found Pl - +ve, thanks to MAPS.

Book Description
When studying the effects of parasites on natural populations, the avian haematozoa fulfills many of the specifications of an ideal model. Featuring a multitude of tables and illustrations, Avian Malaria Parasites and Other Haemosporidia summarizes more than a century of research on bird haemosporidians. For a long time, bird blood parasites served as important models in studying human diseases. Although now largely replaced, the wealth of data and research remain. With chapters addressing life cycles and morphology, pathogenicity, ultrastructure, geographical distribution, and illustrated keys to all known species of the parasites, this book is a masterful assessment of the biology of bird haemosporidian parasites.

Book Description
The story of one woman’s remarkable work with a trio of charismatic, endangered bird species—and her discoveries about the devastating threats that imperil them. In Feather Trails, wildlife biologist and birder Sophie A. H. Osborn reveals how the harmful environmental choices we’ve made—including pesticide use, the introduction of invasive species, lead poisoning, and habitat destruction—have decimated Peregrine Falcons, Hawaiian Crows, and California Condors. In the Rocky Mountains, the cloud forests of Hawai’i, and the Grand Canyon, Sophie and her colleagues work day-to-day to try to reintroduce these birds to the wild, even when it seems that the odds are steeply stacked against their survival. With humor and suspense, Feather Trails introduces us to the fascinating behaviors and unique personalities of Sophie’s avian charges and shows that what endangers them ultimately threatens all life on our planet. More than a deeply researched environmental investigation, Feather Trails is also a personal journey and human story, in which Sophie overcomes her own obstacles—among them heat exhaustion, poachers, rattlesnakes, and chauvinism. Ultimately, Feather Trails is an inspiring, poignant narrative about endangered birds and how our choices can help to ensure a future not only for the rarest species, but for us too. "An intimate look at the wonder and effort needed for working with endangered species in the wild. [Osborn's] matter-of-fact writing style and wry humor make the reader part of the action."—Booklist (starred review)

Book Description
I characterized a lowland Amazonian assemblage of haemosporidian ("malaria") parasites (Haemoproteus and Plasmodium) of understory birds by analyzing variation in prevalence (proportion of infected host individuals) among years and host species, documenting diversity of haemosporidian evolutionary lineages, and quantifying host specialization. Using standard molecular methods to screen for haemosporidia in 2488 individual birds from 104 species in the Tiputini Biodiversity Station, Ecuador, I found 21.7% to be infected. Prevalence ranged significantly among years and host species. Forty-five putative evolutionary lineages of haemosporidia were identified, by sequencing part of the cytochrome b (cyt b) gene. Based on a comparative analysis, among host species variation in haemosporidian prevalence related positively to level of sexual dimorphism and negatively to foraging height. I assigned 385 parasite individuals to cyt b lineages. These exhibited a wide range of abundance (one to 91 individuals) and host specialization (one to 23 host species). I quantified host specificity by incorporating both phylogenetic relationships (based on genetic data) and frequency distribution among hosts. Based on null model comparisons, six haemosporidian lineages were more specialized than expected by chance. The hosts of these six haemosporidian lineages were on average more abundant than hosts of generalist lineages, but average body size and survival rate did not differ between hosts of specialists and hosts of generalists. Host specificity was also phylogenetically conserved among haemosporidia. Consequently, I performed a comparative regression analysis, controlling for the effect of parasite phylogeny, and found no relationships between host specificity and host abundance, body size, or survival rate. Finally, I applied network analysis in combination with null models to test whether the level of reciprocal specialization (where one parasite lineage associates with only one bird species, which harbors no other parasite lineages) is greater in this tropical assemblage than it is in an equivalent temperate assemblage. Assuming coevolution proceeds towards reciprocal specialization, it should be greater in the tropics, where coevolution has historically been hypothesized to be more important in species diversification. I found no evidence for this hypothesis; instead, reciprocal specialization was greater in the temperate site.

Book Description
This authoritative handbook, part of the Helm Identification Guide series, looks in detail at the beautiful antpittas. Elusive study organisms for ornithologists and highly prized additions to the birder's life-list, the antpittas (Grallariidae) and gnateaters (Conopophagidae) are among the most poorly known Neotropical bird groups. This authoritative handbook is the first book dedicated solely to these two families, combining an exhaustive review of more than two centuries of literature with original observations by the author and many knowledgeable contributors. Antpittas and Gnateaters provides a thorough guide to the identification and ecology of these birds, with detailed maps accompanying the text. A series of superb plates illustrate most of the 156 recognized taxa; supplemented by more than 250 colour photographs, the immature plumages and natural history of many species are depicted for the first time. This book is the ultimate reference on these remarkable and beautiful birds, and an indispensable addition to the libraries of researchers and birders for many years to come.
