An evolutionary perspective on genetic load in small, isolated populations as informed by whole genome resequencing and forward-time simulations.

Small populations are vulnerable to increased genetic load and drift that can lead to reductions in fitness and adaptive potential. By analyzing 66 individual whole genomes of Montezuma Quail (Cyrtonyx montezumae) from multiple populations, we illustrate how genetic load is dynamic over evolutionary time. We show that Montezuma Quail are evolving like a ring species, where the terminal extant populations from Arizona and Texas have been separated for ~16,500 years.

Detection of via integrated serological and molecular analyses in coyotes from Texas, United States.

Wild canids serve as reservoir for various vector-borne pathogens of veterinary and medical importance, including the canine heartworm, . In North and Central America, coyotes () may be a relevant reservoir host for heartworm transmission. The objective of this study was to determine the occurrence of in coyotes across Texas using integrated antigen detection test and molecular assays.

Understanding tolerance for an invasive species: An investigation of hunter acceptance capacity for wild pigs (Sus scrofa) in Texas.

Invasive species and their establishment in new areas have significant impacts on the ecological, economic, and social well-being of our planet. Wild pigs (Sus scrofa) are one of the world's most formidable invasive species, particularly in the United States. They cause significant damage to agriculture and ecosystems, and can transmit diseases to livestock, wildlife, and people.

Prevalence of common tick-borne pathogens in white-tailed deer and coyotes in south Texas.

Determining which wildlife hosts are involved in the enzootic cycles of tick-borne diseases (TBD) enables enhanced surveillance and risk assessment of potential transmission to humans and domestic species. Currently, there is limited data to indicate which tick-borne pathogens (TBP) can infect coyotes. Additionally, limited surveillance data for white-tailed deer (WTD) in south Texas is available.

Dynamics of animal joint space use: a novel application of a time series approach.

Background: Animal use is a dynamic phenomenon, emerging from the movements of animals responding to a changing environment. Interactions between animals are reflected in patterns of joint space use, which are also dynamic. High frequency sampling associated with GPS telemetry provides detailed data that capture space use through time.

Molecular prevalence and ecoregion distribution of select tick-borne pathogens in Texas dogs.

Tick-borne diseases (TBD), caused by borrelial, rickettsial and babesial pathogens, are common across the United States and can cause severe clinical disease in susceptible hosts, such as domestic dogs. However, there are limited TBD molecular epidemiological reports for dogs in Texas, and none for the non-Lyme borrelial pathogen responsible for causing tick-borne relapsing fever (TBRF). Therefore, data to support the prevalence of TBRF in the canine population is inadequate.

Inadequate thermal refuge constrains landscape habitability for a grassland bird species.

Ecologists have long recognized the influence that environmental conditions have on abundance and range extent of animal species. We used the northern bobwhite (; hereafter bobwhite) as a model species for studying how microclimates serve as refuge against severe weather conditions. This species serves as an indicator or umbrella species for other sensitive ground-nesting, grassland obligate species.
