The margay is a small wild cat native to Central and South America. A solitary and nocturnal cat, it lives mainly in primary evergreen and deciduous forest.
The antbirds are a large passerine bird family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas, the tapaculos, the gnateaters and the ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes.
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism.

The Cerrado is a vast ecoregion of tropical savanna in eastern Brazil, being present in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Maranhão, Piauí, Bahia, Minas Gerais, São Paulo, Paraná and the Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the Planalto. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and gramineous-woody savanna. The Cerrado also includes savanna wetlands and gallery forests.
The white-ruffed manakin is a sub-oscine (Tyranni), passerine bird in the manakin family. It is a resident breeder in the tropical New World from eastern Honduras to northwestern Colombia. Its typical habitat is wet forest, adjacent clearings and tall secondary growth. It is a small, plump bird about 10 centimetres (4 in) long. Males have glossy blue-black plumage with a white erectile ruff on the throat and females are green. At breeding time, males are involved in lekking behaviour on the forest floor during which they puff out their neck feathers. This is a fairly common species with a wide range.
The white-crowned manakin is a small passerine bird in the manakin family Pipridae. This common and extremely widespread manakin is one of the most easily identified, even in female plumage. It is a resident breeder in the tropical New World from Costa Rica to northeastern Peru and eastern Brazil. It was traditionally placed in the genus Pipra, but is now placed in its own monotypic genus Pseudopipra. It is a small, compact bird about 10 cm (3.9 in) long. Males have black plumage with a white crown which can be erected as a crest, the only member of the Pipridae to possess both an all-black body and a gleaming white crown. Females and juveniles are olive-green, with a grey head and throat, and greyish-green or olive underparts. At breeding time, males are involved in a lekking behaviour. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The helmeted manakin is a species of smallpasserine bird in the manakin family Pipridae. Unlike most manakins, a family associated with tropical rainforests, the helmeted manakin inhabits the seasonally dry Cerrado savanna of Central Brazil.
The long-tailed manakin is a species of bird in the family Pipridae native to Central America where it inhabits both wet and dry tropical and subtropical forests. It is a small, plump bird about 10 centimetres (4 in) long. Males have black plumage with a blue back and a red crown, and the two central tail feathers are greatly elongated. Females and juveniles are olive-green with paler underparts. At breeding time, males are involved in a cooperative lekking behaviour with a complex coordinated courtship dance. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The blue-capped manakin is a species of bird in the family Pipridae. The males have a brilliant blue cap; some have black, others have green body plumage, but the relationship between the subspecies is not well understood.
The kinglet manakin or eastern striped manakin is a small South American species of passerine bird in the manakin family Pipridae. It is found in the Atlantic Forest of south eastern Brazil. It was formerly considered conspecific with the striolated manakin with the common name "striped manakin". Males have a bright red crown, which the females lack.
The red-capped manakin is a species of bird in the family Pipridae. It is found in Belize, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Peru and Panama. Its natural habitat is subtropical or tropical moist lowland forest.
Defaunation is the global, local, or functional extinction of animal populations or species from ecological communities. The growth of the human population, combined with advances in harvesting technologies, has led to more intense and efficient exploitation of the environment. This has resulted in the depletion of large vertebrates from ecological communities, creating what has been termed "empty forest". Defaunation differs from extinction; it includes both the disappearance of species and declines in abundance. Defaunation effects were first implied at the Symposium of Plant-Animal Interactions at the University of Campinas, Brazil in 1988 in the context of Neotropical forests. Since then, the term has gained broader usage in conservation biology as a global phenomenon.
The Margaret Morse Nice Medal is an ornithological award made annually by the Wilson Ornithological Society (WOS). It was established in 1997 and named in honour of ornithologist Margaret Morse Nice (1883-1974). The medal recipient is expected to give the plenary lecture at the WOS annual general meeting.
Patricia G. Parker is a North American evolutionary biologist who uses molecular techniques to assess social structures, particularly in avian populations. Her interests have shaped her research in disease transmission and population size, particularly in regard to bird conservation. She received her B.S. in Zoology in 1975 and her Ph.D. in Behavioral Ecology in 1984, both from the University of North Carolina at Chapel Hill. From 1991 to 2000, Parker was an Assistant and Associate Professor in the Department of Evolution, Ecology, and Organismal Biology at Ohio State University. Since 2000, she is the Des Lee Professor of Zoological Studies at the University of Missouri–St. Louis.
John Weaver Fitzpatrick is an American ornithologist primarily known for his research work on the South American avifauna and for the conservation of the Florida scrub jay. He is currently the Louis Agassiz Fuertes Director of the Cornell Lab of Ornithology in Ithaca, New York.
Altitudinal migration is a short-distance animal migration from lower altitudes to higher altitudes and back. Altitudinal migrants change their elevation with the seasons making this form of animal migration seasonal. Altitudinal migration can be most commonly observed in species inhabiting temperate or tropical ecosystems. This behavior is commonly seen among avian species but can also be observed within other vertebrates and some invertebrates. It is commonly thought to happen in response to climate and food availability changes as well as increasingly due to anthropogenic influence. These migrations can occur both during reproductive and non-reproductive seasons.
Catherine H. Graham is an American team leader and senior scientist working on the Biodiversity & Conservation Biology, and the Spatial Evolutionary Ecology research units at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL. From 2003 to 2017 she was an Assistant, Associate, or Full Professor of Ecology and Evolution at the Stony Brook University, and since her appointment at the WSL in 2017 she has maintained adjunct status there. She received both her M.S. degree (1995) and her Ph.D. (2000) from the University of Missouri at St. Louis, and did post-doctoral training at the Jet Propulsion Laboratory and the University of California, Berkeley. She studies biogeography, conservation biology, and ecology. Catherine H. Graham is most noted for her analysis of statistical models to describe species' distributions. This work with Jane Elith is useful in determining changes in biodiversity resulting from human activities. Her paper on niche conservatism with John J. Wiens is also highly cited. They focused on how species' retention of ancestral traits may limit geographic range expansion. In many of her papers, she has sought to unite ecology and evolutionary biology to derive a better understanding of the processes driving species diversity patterns. In particular, she and Paul Fine laid out a framework for interpreting community assembly processes from a phylogenetic approach to quantifying beta diversity.
