Delayed plumage maturation in green ‐backed flycatchers (Ficedula elisae): An evidence of female mimicry
AbstractDelayed plumage maturation (DPM) is the delayed acquisition of an adult color and pattern of plumage until after the first potential breeding period. Among the hypotheses proposed to explain DPM, the female mimicry hypothesis (FMH) has received considerable attention. FMH predicts that after ‐second‐calendar‐year (ASY) males should attack ASY males more than second‐calendar‐year (SY) males and females, while no difference between the two latter. Few studies have been thought as support for FMH, while in fact most of them give no conclusive evidence to the assumption of FMH tha t ASY males are unable to di...

Factors influencing tadpole deposition site choice in a frog with male parental care: An experimental field study
AbstractParents have evolved a variety of strategies to minimize risks to their offspring, including complex choices regarding suitable rearing sites, based on abiotic and biotic factors, which differentially affect offspring survival. Because availability and quality of these sites are variable, parents may have to choose between immediately available lower ‐quality rearing sites or extended search time. In some frog species with larval transport, parents are known to select bodies of water that are free of predators, cannibalistic tadpoles, or intraspecific competitors for larval deposition and rearing sites. We tested...

Sprint speed is not reduced by exaggerated male weapons in a flower beetle Dicronocephalus wallichii
AbstractExaggerated sexually selected traits are assumed to decrease the mobility of bearers. However, previous empirical studies have often failed to support this assumption, possibly because locomotor performance represents the integration of numerous morphological, physiological and behavioural traits. Males of a flower beetleDicronocephalus wallichii Pouillaude 1914 (Coleoptera: Scarabaeidae: Cetoniinae) possess elongated forelegs and a pair of exaggerated horns, which are used as dual weapons in male –male competition for mates. We investigated whether these two sexual traits impede the maximum sprint speed on bambo...

Attendance to egg clutches by male Kurixalus eiffingeri increases hatching success and decreases predation by invasive slugs (Parmarion martensi) in Taiwan
AbstractInvasive species have a significant impact on amphibians, and most notably Chytrid fungi together with a few vertebrates. However, invasive terrestrial invertebrates are seldomly demonstrated to have a negative effect on their host environment, and few studies investigated the behavioural interactions between invasive and local species, limiting our knowledge of the adaptive response adopted by local organisms. These responses include whether parenting animals recognize predators as threats to their offspring and whether parental care is adequately corrected. Here, through manipulative experiments on a population o...

Female mate choice is a reproductive isolating barrier in Heliconius butterflies
AbstractIn sexually reproducing organisms, speciation involves the evolution of reproductive isolating mechanisms that decrease gene flow. Premating reproductive isolation, often the result of mate choice, is a major obstacle to gene flow between species because it acts earlier in the life cycle than other isolating barriers. While female choice is often considered the default mode in animal species, research in the butterfly genusHeliconius, a frequent subject of speciation studies, has focused on male mate choice. We studied mate choice byHeliconius cydno females by pairing them with either conspecific males or males of ...

Modulation of trail laying in the ant Lasius neglectus (Hymenoptera: Formicidae) and its role in the collective selection of a food source
In this study, we explored the feeding behaviour of the invasive garden antLasius neglectus. In particular, we investigated its ability to select the more profitable resource in a binary choice and its pheromonal trail marking. When facing a choice between two different energy sources, workers were rapidly recruited to the most profitable one, although both the speed of the recruitment and the number of ants varied considerably with the difference between the solutions. When facing two identical sources, workers were massively recruited onto one of the two in 80% of tests, whereas in the remaining 20% the workforce was spl...
