Using step width to compare locomotor biomechanics between extinct, non-avian theropod dinosaurs and modern obligate bipeds [PDF]

open access: yes, 2017
How extinct, non-avian theropod dinosaurs locomoted is a subject of considerable interest, as is the manner in which it evolved on the line leading to birds. Fossil footprints provide the most direct evidence for answering these questions. In this study,

Current understanding of lymphoproliferative disease virus in wild turkeys

open access: yesWildlife Society Bulletin, Volume 49, Issue S1, December 2025.
Lymphoproliferative disease virus (LPDV) is a retrovirus that can cause a spectrum of disease in wild turkeys (Meleagris gallopavo), from subclinical infection to lymphoid tumors. We reviewed the literature to summarize our current understanding of LPDV, including disease presentation, surveillance, impact on fitness, spatiotemporal distribution, and ...

Carcass analysis of four quails species in Mexico State [PDF]

open access: yes, 2014
The human diet consists of a great diversity of foods in where the most common source of protein comes from animals; mainly from fattening species of pigs, beef, chickens, and sheep due to intensive farming high fat content. The current study was aimed

Environmental influences on development of aflatoxins in supplemental feed for wildlife

open access: yesWildlife Society Bulletin, Volume 49, Issue S1, December 2025.
Millions of people provide grains as supplemental feed for wildlife. Environmental conditions can lead to those grains developing deleterious concentrations of aflatoxins from naturally occurring Aspergillus fungi. We studied aflatoxin development in grains under controlled conditions to provide best practices to minimize the risk of aflatoxin exposure

Helminths and the northern bobwhite population decline: A review

open access: yesWildlife Society Bulletin, 2016
Long‐term data from the Breeding Bird Survey and Christmas Bird Count indicate that northern bobwhite (Colinus virginianus; hereafter, bobwhite) populations have declined since 1961 in all but 1 of the 31 states they occupy within the United States. This

Detection of Modality-Specific Properties in Unimodal and Bimodal Events during Prenatal Development [PDF]

open access: yes, 2010
Predictions of the Intersensory Redundancy Hypothesis (IRH) state that early in development information presented to a single sense modality (unimodal) selectively recruits attention to and enhances perceptual learning of modality-specific properties of ...

Vital rates and population trajectory of a declining eastern wild turkey population in southeastern Oklahoma

open access: yesWildlife Society Bulletin, Volume 49, Issue S1, December 2025.
To investigate underlying demographic rates driving apparent declines of eastern wild turkeys (Meleagris gallopavo silvestris) in Oklahoma, we quantified current stage‐specific survival and reproductive rates. Our objective was to determine the current population trajectory using field‐derived vital rates and identify which demographic factors had the ...

Effects of broadcasting calls during surveys to estimate density and occupancy of northern bobwhite

open access: yesWildlife Society Bulletin, 2012
We assessed the effects of using a broadcast caller during surveys and increasing survey duration to estimate northern bobwhite (Colinus virginianus) density and occupancy.

Does haemosporidian infection affect hematological and biochemical profiles of the endangered Black-fronted piping-guan (Aburria jacutinga)? [PDF]

open access: yes, 2013
Infectious diseases can cause deleterious effects on bird species, leading to population decline and extinction. Haemosporidia can be recognized by their negative effects on host fitness, including reproductive success and immune responses. In captivity,

Lactobacillus colini sp. nov., isolated from Northern Bobwhite (Colinus virginianus)

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2017
Biochemical and molecular studies were performed on five unknown bacterial strains isolated from the intestinal contents of Northern Bobwhites (Colinus virginianus) collected from western Texas, USA. The strains were Gram-stain-positive, catalase-negative, non-spore-forming rods arranged in single cells, pairs or short chains.
