Abstract Many plant species have seeds embedded in their fleshy pulp to attract frugivores, which enhances the chance of seed dispersal. However, some tropical plants are evolved with sharp spines …
Abstract Species of scorpionfly (Mecoptera) in the family Panorpidae perform wing-waving behaviors, whereby they rotate their front and rear wings at the same time. Previous studies have suggested that a …
Abstract Many sexual selection studies focus on conspicuous ornaments, such as long tails, but neglect to investigate inconspicuous traits. Here, we studied a well-known sexual selection mechanism, the Darwin–Fisher mechanism …
Abstract Theory shows that polyandry (mating with multiple males within a reproductive season) works as bet-hedging to increase the geometric mean fitness (GMF) of polyandrous genotype over generations and avoid …
Abstract Theory suggests honest status signals mediate agonistic interactions between unfamiliar individuals, but may be less important during interactions between familiar individuals. Few studies have tested receiver responses to status …
Abstract Costs of parental care can include increased physical, physiological, and behavioral demands and reduced prospects for future reproduction. Therefore, animals may benefit from recognizing and discriminating their own offspring …
Abstract We described and compared the mating behavior and morphology of the reproductive system in chromodorid nudibranchs, then, examined how extensively the unique usage of the penis (autotomy and sperm …
Abstract We investigated whether two South-Western Atlantic wrasses [Halichoeres penrosei (models) and Thalassoma noronhanum (mimics)] were involved in social mimicry. In mixed shoals, we recorded species-specific abundances and lengths, and …
Abstract Many animals adjust their reproductive investment in line with their current competitive abilities. High-quality individuals may breed in the peak breeding period because they have a greater probability of …
Abstract By gathering data on people during their ordinary daily activities, we tested if looking at, but not manipulating, smartphones led to a mimicry response in the observer. Manipulating and …
