net effects of ecotourism on threatened species survival.	many threatened species rely on ecotourism for conservation funding, but simultaneously suffer direct ecological impacts from ecotourism. for a range of iucn-redlisted terrestrial and marine bird and mammal species worldwide, we use population viability analyses to calculate the net effects of ecotourism on expected time to extinction, in the presence of other anthropogenic threats such as poaching, primary industries and habitat loss. species for which these calculations are currently possible, ...	2016	26886876
health assessment of captive psittacine species in prerelease programs at costa rican rescue centers.	with stricter laws regulating the capture and possession of wild animals in costa rica, local wildlife-rescue centers have been overwhelmed by an influx of confiscated or relinquished illegal pets, specifically of psittacine species. as part of a nationwide health-assessment program targeting these centers, 122 birds representing five psittacine species ( ara macao, amazona autumnalis, amazona auropalliata, amazona farinosa, aratinga finschi) and one hybrid macaw ( ara macao × ara ambiguus) were ...	2017	29297799
intestinal and blood parasites in scarlet (ara macao) and great green (ara ambigua) macaws in wildlife rehabilitation centers in costa rica.	costa rica undertakes continuous efforts to recover the native population of macaw species through rehabilitation programs for breeding and releasing birds in protected areas. in the summer of 2018, a total of 107 scarlet (ara macao) and 93 great green (ara ambigua) macaws were sampled in four wildlife rehabilitation centers in costa rica. fecal samples representing 200 individuals were analyzed for intestinal parasites, and 23 individuals were sampled for hemoparasites. ascaridia and capillaria ...	2020	32549569
