We assessed responses in grooming behavior to ectoparasite densities naturally occurring white-tailed deer (Odocoileus virginianus) southwest Alabama, and tested predictions of the stimulus-driven programmed models with respect intraspecific body size vigilance. Stimulus-driven predicts greater tick would lead an increase grooming, whereas model a higher rate decrease densities. Within model, smaller individuals are predicted groom more host fewer ticks, and, due increased vigilance,...
Abstract Exponential increase in respiration rate with increasing temperature poikilotherms is well documented, however, the of change varies greatly across copepod taxa. Studies often report magnitude change, but multiple temperatures equivocal. We used 32 studies spanning 78 yrs research and 50 species (three orders) to quantify percent rates per one‐unit temperature. found that increased by approximately 7% °C water orders Calanoida, Cyclopoida, Harpacticoida. Neither food availability...
An important component of life history theory is understanding how natural variation arises in populations. Both endogenous and exogenous factors contribute to organism survival reproduction, therefore, it understand such are both beneficial detrimental population dynamics. One ecologically relevant factor that influences the aquatic organisms ultraviolet (UV) radiation. While majority research has focused on potentially effects UV radiation organisms, few studies have evaluated hormetic...
While the specific mechanisms of colour production in biological systems are diverse, mechanics straightforward and universal. Colour is produced through selective absorption light by pigments, scattering nanostructures or a combination both. When Tigriopus californicus copepods were fed carotenoid-limited diet yeast, their orange-red body coloration became faint, but eyespots remained unexpectedly bright red. Raman spectroscopy indicated clear signature red carotenoid pigment astaxanthin...
Climate change is driving a need to understand how changing temperatures affect organism physiology, including whole-organism metabolic rate. This process sometimes quantified using Q10 values, or temperature coefficients. Although intuitive at first glance, values are limited measuring effects two temperatures, must be assessed with similar across related ranges comparable, and treat as piecemeal. I recommend thermal ecologists adopt alternative effect sizes, for example, "percent change"...
Abstract To produce viable offspring, organisms may assess mates via criteria that include traits, such as sex, species, age, reproductive status, population identity and individual quality. Copepods are small, ubiquitous crustaceans live in freshwater marine systems around the world whose patterns of mate choice have been long studied numerous species. Herein, we synthesized decades experiments describing sexual selection copepods to importance mating criteria. We used formal,...
