Explosive Pleistocene range expansion leads to widespread Amazonian sympatry between robust and gracile capuchin monkeys
Aim Capuchin monkey species are widely distributed across Central and South America. Morphological studies consistently divide the clade into robust and gracile forms, which show extensive sympatryExpand
Is the decline of desert bighorn sheep from infectious disease the result of low MHC variation?
Bighorn sheep populations have greatly declined in numbers and distribution since European settlement, primarily because of high susceptibility to infectious diseases transmitted to them fromExpand
Founder effect in an island population of bighorn sheep
The Tiburon Island population of desert bighorn sheep has increased in size from 20 founders in 1975 to approximately 650 in 1999. This population is now the only population being used as the sourceExpand
Isolation of novel and known genes from a human fetal cochlear cDNA library using subtractive hybridization and differential screening.
We used a combination of subtractive hybridization and differential screening strategies to identify genes that may function normally in hearing and, when mutated, result in deafness. A human fetalExpand
We examined the effect of geographic isolation on morphology, genetic structure, and abundance of the Sooty-capped Bush Tanager (Chlorospingus pileatus), an endemic species restricted to highlands ofExpand
Prevalence of Psittacine Beak and Feather Disease Virus and Avian Polyomavirus in Captivity Psittacines from Costa Rica
Psittacine beak and feather disease virus (PBFDV) and avian polyomavirus (APV) are the most common viral diseases in psittacine birds, both affecting feathers and physical appearance of birds.Expand
Genetic variation and population structure in desert bighorn sheep: implications for conservation
Bighorn sheep populations experienced a drastic reduction in both distribution and abundance until the advent of modern wildlife management, where improving viability of extant populations andExpand
Subspecies of the Central American Squirrel Monkey (Saimiri oerstedii) as Units for Conservation
The accurate diagnosis of conservation units now typically includes recognition of genetic diversity and unique evolutionary lineages and is necessary to inform the conservation management ofExpand
Norrie disease gene mutation in a large Costa Rican kindred with a novel phenotype including venous insufficiency
A large Costa Rican kindred has been identified with 15 males affected with congenital blindness, progressive hearing loss, and venous insufficiency. Due to ophthalmological and audio‐otologicalExpand
