Wind energy development is rapidly expanding globally, as are concerns about the potential threats wind facilities pose to bird and bat populations. To date, many studies have explored the direct impacts of wind turbines on wildlife, such as wildlife

Proliferation of wind energy across the Great Plains of the United States has the potential to negatively affect many grassland birds through displacement, avoidance, or changes in nesting ecology. This is troublesome because grassland birds have had

Wind energy development is rapidly increasing within breeding and wintering ranges of many grassland birds in North America. Despite recognized environmental benefits of such development, wind farms have the potential to negatively impact bird commun

We investigated indirect effects of wind turbines on nesting success of scissor-tailed flycatchers (Tyrannus forficatus). We tracked the fate of 32 nests at Wolf Ridge Wind, LLC, Cooke County, Texas, during the breeding season in 2009. Overall rates

Signaling plays a critical role in social behavior, particularly in polygynous systems where males compete with rival males and use signals to attract mates. We quantified visual signals and social behavior in two previously unstudied species of cham

Madagascar is a high conservation priority. Rainforests receive most of the focus, but the dry deciduous and spiny forests of south-western Madagascar house many endemics, are under high deforestation pressure, and remain largely unprotected. Charism

In polygynous mating systems, sexual selection can drive the evolution of male characters beneficial to winning fights for mates (intrasexual selection), for improving the mating success of males through mate choice (intersexual selection), or both.

The ≈28,300 species of tetrapods (four-limbed vertebrates) almost exclusively have perennial life spans. Here, we report the discovery of a remarkable annual tetrapod from the arid southwest of Madagascar: the chameleon Furcifer labordi , with a po

We compared the natural ultraviolet B (UV‐B) exposure, dietary vitamin D, and skin‐generated vitamin D synthesis for adult males of two species of Jamaican anoles. The more shade‐tolerant and thermal‐conforming Anolis lineotopus merope, rarel

We developed a non-invasive DNA sampling method and 15 tetranucleotide microsatellite markers for Texas horned lizards (Phrynosoma cornutum). Swabbing the cloaca with a small cotton swab and preserving the cells in lysis buffer was an effective metho
