Mitochondrial Genome Analysis of Philippine Eagles (<i>Pithecophaga jefferyi</i> Ogilvie-Grant 1896) From the Greater Mindanao Faunal Region. [PDF]

open access: yesEcol Evol
Mitogenome sequencing is a promising alternative for the genetic studies of animals. In this work, we examined the genetic diversity of the critically endangered and endemic Philippine eagles and their evolutionary relationship to other birds of prey.

The status quo is imperiled: Acknowledging the issue of range‐shifting wildlife species

open access: yesWildlife Society Bulletin, EarlyView.
Rapid climate and land‐use change are reshaping wildlife distributions, forcing managers to confront difficult decisions that challenge the traditional “status quo” approach. Range contractions of snow‐dependent species such as the snowshoe hare (Lepus americanus; left photo) may increasingly require practitioners to recognize and plan for unavoidable ...

Vultures and others scavenger vertebrates associated with man-sized pig carcasses: a perspective in Forensic Taphonomy

open access: yesZoologia (Curitiba), 2013
The activity of vertebrates that feed on corpses can modify the chronology of the decomposition process and interfere with postmortem interval estimates.

Landscape transformations produce favorable roosting conditions for turkey vultures and black vultures

open access: yesScientific Reports, 2021
Recent increases in turkey vulture (Cathartes aura) and black vulture (Coragyps atratus) populations in North America have been attributed in part to their success adapting to human-modified landscapes.

Measuring the edges of species' geographic ranges

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The fundamental unit of spatial ecology is a species range: the geographical area that it occupies. Species ranges are delineated by range edges (also known as boundaries or limits). Why range edges occur where they do and not elsewhere, and what makes them move, has been an active area of research since the 19th century.

Known occurrences and modelled distribution and sympatry between Vultur gryphus and Coragyps atratus

open access: yes, 2018
Climate change can cause geographic displacement of the ecological niche of a species, so that similar species that previously did not coexist could begin to face new interactions such as competition.

Regional Intravenous Anaesthesia (Bier's block) in Black-headed Vulture (Coragyps atratus) Submitted to Digit Amputation [PDF]

open access: yes, 2022
Background: The Coragyps atratus flies long distances in search of food and has a marked behaviour of food competition. Since they are frequently found in areas of recent human occupation, they are subject to trauma, which may require surgical ...

Comportamiento reproductivo de Chroicocephalus cirrocephalus (Vieillot, 1818) (Charadriiformes: Laridae) y Coragyps atratus (Bechstein‎, 1793) (Cathartiformes: Cathartidae) en el humedal costero humedal de Villa, Lima-Perú [PDF]

open access: yes, 2023
The Villa Wetland, in Lima, Peru, is home to a great diversity of fauna such as birds. The reproduction of birds is important for their natural history, and studies are necessary to help in the conservation and management of both birds and the spaces ...
