Ectoparasite load generates habitat-specific variation in colour badge intensity and badge size in male lizards Open
The severity of parasitic infections can mediate the differential expression of signals among populations, creating variation in signal intensity. Male signals (patch size and brightness) were quantified in Florida scrub lizards (Sceloporu…

Capsaicin-treated bait is ineffective in deterring non-target mammals from trap disturbance during invasive lizard control Open
Excluding non-target species from invasive species control efforts can be challenging due to non-target attraction to trap structure, baits, and lures. Various methods have been used to deter non-target species from entering or disturbing …

When Food Fights Back: Skull Morphology and Feeding Behavior of Centipede-Eating Snakes Open
Synopsis Feeding is a complex process that involves an integrated response of multiple functional systems. Animals evolve phenotypic integration of complex morphological traits to covary and maximize performance of feeding behaviors. Speci…

Escape behaviour varies with distance from safe refuge Open
Locomotor performance and behaviour are important for escape from predators, yet the intersection of these strategies is poorly studied. Escape behaviour is context dependent, and optimal escape theory predicts that animals that are farthe…

Applied Functional Biology: Linking Ecological Morphology to Conservation and Management Open
Synopsis Many researchers work at the interface of organisms and environment. Too often, the insights that organismal, or functional, biologists can bring to the understanding of natural history, ecology, and conservation of species are ov…

Conservation and Management Strategies Create Opportunities for Integrative Organismal Research Open
Synopsis Conservation and management activities are geared toward the achievement of particular goals for a specific species, or groups of species, at the population level or higher. Conversely, organismal or functional research is typical…

Acclimatization in the physiological performance of an introduced ectotherm Open
Phenotypic flexibility may facilitate range expansion by allowing organisms to maintain high levels of performance when introduced to novel environments. Phenotypic flexibility, such as reversible acclimatization, permits organisms to achi…

Mite load predicts the quality of sexual color and locomotor performance in a sexually dichromatic lizard Open
Since Darwin, the maintenance of bright sexual colors has recurrently been linked to mate preference. However, the mechanisms underpinning such preferences for bright colors would not be resolved for another century. Likely, the idea of se…

Habitat management alters thermal opportunity Open
Ectotherms engage in behavioral thermoregulation to optimize body temperatures, however, thermoregulatory effort varies across species, over time, and among habitats. Classic cost‐benefit models of ectothermic thermoregulation postulate th…

Forelimb position affects facultative bipedal locomotion in lizards Open
Recent work indicates that bipedal posture in lizards is advantageous during obstacle negotiation (Parker and McBrayer, 2016). However, little is known about how bipedalism occurs beyond a lizard's acceleratory threshold. Furthermore, no s…

The effects of multiple obstacles on the locomotor behavior and performance of a terrestrial lizard Open
Negotiation of variable terrain is important for many small terrestrial vertebrates. Variation in the running surface due to obstacles (woody debris, vegetation, rocks) can alter escape paths and running performance. The ability to navigat…
