Abstract Social experiences can be useful sources of information for animals charged with making fitness‐related decisions. Fighting experience alter an animal's perception its fighting ability possibly leading to changes in future contest decisions, which may increase/decrease their probability winning contests. Winner and loser effects have been revealed a wide array animals, but studies using reptilian models are rare. This study investigated the impact on performance outcome green anole...
Cold tolerance, the ability to cope with low temperature stress, is a critical adaptation in thermally variable environments. An individual's cold tolerance comprises several traits including minimum temperatures for growth and activity, survive severe cold, resume normal function after subsides. Across species, these are correlated, suggesting they were shaped by shared evolutionary processes or possibly share physiological mechanisms. However, extent which their associated mechanisms...
ABSTRACT To maximize reproductive success, many animal species have evolved functional sex change. Theory predicts that transitions between sexes should occur when the fitness payoff of current is exceeded by opposite sex. We examined phenotypic differences in a sex-changing vertebrate, mangrove rivulus fish (Kryptolebias marmoratus), to elucidate potential factors might drive ‘decision’ switch Rivulus populations consist self-fertilizing hermaphrodites and males. Hermaphrodites transition...
Abstract Tolerance of climatic stressors is an important predictor the current distribution insect species, their potential to invade new environments, and responses rapid climate change. Cold stress causes acute injury nerves muscles, here we tested hypothesis that low temperature sublethal deficits in locomotor behaviors are dependent on neuromuscular function. To do so, applied a previously developed assay, iterative negative geotaxis (RING) investigate behavioral consequences cold...
Upper and lower thermal limits of plants animals are important predictors their performance, survival, geographic distributions, essential for predicting responses to climate change. This work describes two high-throughput protocols measuring insect limits: one assessing critical minima (CTmin), the other heat knock down time (KDT) in response a static stressor. In CTmin assay, individuals placed an acrylic-jacketed column, subjected decreasing temperature ramp, counted as they fall from...
In many species, males tend to behave more aggressively than females and female aggression often occurs during particular life stages such as maternal defence of offspring. Though studies have revealed differences in between the sexes, few compared sexes terms their neuroendocrine responses contest experience. We investigated sex endocrine response social challenge using mangrove rivulus fish, Kryptolebias marmoratus. this is determined environmentally, allowing us produce hermaphrodites...
The lesson plan described here provides students hands-on, scientific experiences that relate to the globally important issue of climate change and its impacts on animals. Students use method basic components experimental design investigate how animals cope with changing temperatures. In our modifiable 6-week plan, which is appropriate for both science majors non-majors, learn design, conduct analyze an experiment addressing fruit flies can acclimate temperatures respond appropriately....
