Feral hogs are an economic and ecologically destructive invasive species. Because they alter the vegetation community via their foraging behavior and through consumption of acorns to suppress oak regeneration, they almost certainly affect the bird community although this is has not yet been assessed.

Invasive species are ecologically and economically costly. If potentially invasive species are identified before they can be established, great harm can be averted. Here, we have reviewed over 19,000 wildlife species in the legal trade to evaluate which are potential invaders.

|
July 2023
|
Examination of behavioral patterns of 3 co-occurring mesopredators that often live near people. Understanding these patterns can allow us to better understand how these species can persist in human-dominated landscapes, the fitness consequences of their adaptations, and potentially human-wildlife conflict.

|
August 2023
|
The loggerhead shrike is declining rapidly across its range and we do not know the causes. Here, we investigate the potential role of agricultural chemicals in reducing the fitness of the enigmatic species.

|
March 2024
|
Agricultural toxins are known to cause a variety of effects, either detrimental or adaptive, in off-target species. Here, we investigate the potential sublethal effects of widespread neonicotinoids on the ecology and behavior of a declining songbird, the Loggerhead Shrike.

Armadillos are rapidly expanding their geographic range in the United States. Due to their habitat altering burrowing behavior, they are sure to have both positive and negative effects on native wildlife.

Pesticides can have profound effects of food webs due to their indiscriminate killing of invertebrates. However, less attention has been focused on the indirect effects of non-target vertebrates living in agricultural settings. Here, we explore how pesticides may be altering the gut microbiome of the Loggerhead Shrike.

|
Grassland birds are the fastest-declining bird guild in North America. Here, we show results from an analysis testing the ability of a novel landscape metric--spatial covariance--for identifying grassland core habitat to target conservation.
