Effect of stress on female-specific ornamentation.
Signal honesty is theorized to be maintained by condition-dependent trait expression. However, the mechanisms mediating the condition dependence of sexually selected traits are often unknown. New work suggests that elevated glucocorticoid levels during physiological stress may play a role in maintaining signal honesty. Here, we experimentally examine the effect of both chronic and acute stress ...

متن کاملMHC Genotype and Ornamentation
Differences among males in immunocompetence can affect resistance to parasites and diseases, and sexual ornaments have been suggested to function as indicators of additive genetic variation in disease resistance, health and condition in the good gene models of sexual selection. In this paper the role of genetic variation in the immune system is discussed as an alternative route to explore wheth...
متن کاملSpeech Recognition under Stress Condition
The objective of this work is to conduct a speech recognition study and evaluate the performance of the same under stressed condition. The speech recognition study is conducted both in isolated word recognition and keyword spotting approaches. The word models are built during training using speech collected from neutral condition. During testing these models are tested with speech signals colle...
متن کاملSex and Sexual Ornamentation Associated with Survival of the Cyprinid Fish, Rutilus rutilus, under Disease Stress
By conveying information of disease resistance, sexual signals may be used as cues for adaptive mate choice. Here we report observations on survival of laboratory-maintained, wild-collected, sexually mature, ready-to-spawn cyprinid fish, Rutilus rutilus (roach), under accidental epidemic attributed to Flavobacterium psychrophilum, diagnosed using species-specific PCR. The fish were maintained i...
