With the third most biodiverse amphibian fauna in world, Ecuador has bolstered this claim with a particularly high rate of species descriptions recent years. Many being described are already facing anthropogenic threats despite discovered within privately protected reserves areas previously not sampled. Herein we describe new terrestrial frog genus Noblella from recently established Río Manduriacu Reserve, Imbabura, Ecuador. worleyae sp. nov. differs its congeners by having dorsum finely...
Summary Andean Condor Vultur gryphus populations are particularly low in the northern Andes. The species is considered nearly eradicated from Venezuela and listed as “Endangered” Ecuador “Critically Endangered” Colombia. Even though it severely endangered, size of Colombian condor population remains unknown. Using a citizen science-based approach, we conducted first count for Colombia with help 207 observers at 84 simultaneous observation points. We used N-mixture models spatially replicated...
The Andean Condor (Vultur gryphus) in Ecuador is classified as Critically Endangered. Before 2015, standardized and systematic estimates of geographic distribution, population size structure were not available for this species, hampering the assessment its current status hindering design implementation effective conservation actions. In study, we performed first quantitative viability Ecuador. We used a methodological approach that included an ecological niche model to study simultaneous...
Vultures comprise one of the most threatened groups birds worldwide. With a total population not exceeding 6700 mature individuals, and in rapid decline across its range, Andean Condor (Vultur gryphus) is listed as Vulnerable species IUCN red list. Local extinctions are particular concern northern South America, where no more than 340 condors may exist at present. Despite this, quantitative assessments Ecuador, Colombia, Venezuela regarding threats affecting populations. To address we...
We describe a new glassfrog from Río Manduriacu Reserve, Imbabura Province, on the Pacific slopes of Ecuadorian Andes. The species can be distinguished most other glassfrogs by having numerous yellow spots dorsum and lacking membranes among fingers. Both morphological molecular data support placement in genus Nymphargus . present mitochondrial phylogeny discuss speciation patterns this genus; importantly, recent events seem to result effect linearity Finally, although occurs within private...
Abstract Conflicts between rural people and the Endangered Black-and-chestnut Eagle ( Spizaetus isidori ) are a prominent conservation concern in northern Andes, as at least 60 eagles were poached 2000 2022 response to poultry predation. Here, we conducted direct observations analyze diet evaluated how forest cover affects feeding habits of species during nestling-rearing periods 16 nests located different human-transformed Andean landscapes Ecuador Colombia. We analyzed 853 prey items (46...
The Andean Condor (Vultur gryphus) is a culturally iconic wildlife symbol for the South American Andes, but naturally found at very low population densities, and increasingly threatened. Using Range Wide Priority Setting methodology, we (a group of 38 experts) updated historical range (3,230,061 km2), systematized 9998 distribution points across range, identified geographic areas which there was expert knowledge (66%), including where Condors no longer occur (7%), condors are believed to not...
Background and Research Aims The Black-and-chestnut Eagle ( Spizaetus isidori) has a total population of fewer than 1000 adult individuals, is categorized as Endangered at the global level. northern Andes (Ecuador Colombia) represent one last strongholds species. In this study, we analyzed human persecution retaliation or preventive measure against poultry predation, well other threats that have affected species in geographical region between 2000 2022. Methods order to understand faced by...
In most Neotropical countries the proliferation of illegal firearms, limited funding, and low presence authorities precludes effective application top-down governance. Despite that, to our knowledge, governance top predator detriments or benefits people (perceived actual) have never been integrated into an empirical study human‒top conflict. We hypothesize that people's tolerance towards black-and-chestnut eagle (Spizaetus isidori), a predator, will vary based on eagle's perceived...
Background and Research Aims: Little information exists on the breeding behavior of Andean Condor ( Vultur gryphus). Its global population, estimated at 6700 adult individuals, is declining throughout its distribution range. With less than 150 condors, Endangered condor population in Ecuador conservation concern. This study aimed to analyze wild-born Condors Ecuador. Methods: Between 2009 2021, we monitored 22 egg-laying attempts eight nests, evaluated parental care three pairs condors...
Jaguar populations ( Panthera onca ) on the Ecuadorian coast are critically endangered, with only a few dozen individuals remaining in region. In some areas, no records have been documented for decades. Between November 2023 and January 2024, independent camera trap monitoring northwestern Ecuador yielded evidence of presence jaguar, marking significant recovery after seven years absence Manduriacu at least 15 Junín. The jaguar was observed moving through an area approximately 25 km,...
Background and Research Aims Native vertebrate scavenger communities may be affected by free-ranging dogs ( Canis lupus familiaris), but little information is available on this subject. We aimed to evaluate the influence of a community native scavengers propose management conservation actions. Methods Between November 2014 June 2016, we systematically monitored 37 ungulate carcasses in buffer zone Antisana National Park, Andes Ecuador at an elevation range between 3000 4150 m asl. with...
Herein we report the second known record of Emmochliophis fugleri Fritts & Smith, 1969, present first color images species, extend its distribution and elevational range, provide snout–vent tail lengths holotype, demonstrate that condition fused prefrontals is an unreliable diagnostic character for genus Diaphorolepis. Considering rarity this snake as well imminent threat mining poses to Río Manduriacu Reserve, recommend a conservation status Critically...
“Cochranella” megista is an Endangered and rarely encountered species of glass frog that, until now, had been only registered in the Colombian Andes. Here we report this for first time Ecuador, expanding its known distribution ca. 530 km south original range. Additionally, include C. a molecular phylogeny unambiguously place genus Nymphargus, resulting new combination. Habitat both countries fragmented threatened by mining concessions agriculture.
SFeather chewing lice are common and important ectoparasites of birds. Here we report for the first time presence ectoparasite, Colpocephalum trichosum Harrison1916 (Phthiraptera: Menoponidae on Andean condor Vultur gryphus Linnaeus, 1758 from North high Andes Ecuador in Pichincha province. A total 20 louse specimens were collected analyzed one free-living female juvenile host. Additionally, resolution photographs included, a discussion potential implications conservation this threatened...
