Models of fertilization kinetics
(2015)
Fertilization functions describe how the number of realized fertilizations depends on gamete numbers or density. They provide insight into the fertilization process, and are important components in models on the evolution ...
Tight knit under stress
(2015)
The movement of colonies from one nest to another is a frequent event in the lives of many social insects and is important for their survival and propagation. This goal-oriented task is accomplished by means of tandem ...
Hybridization generates a hopeful monster
(2016)
Compared with other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes. Here we report observing one F1-hybrid individual that ...
Conflict between background matching and social signalling in a colour-changing freshwater fish
(2016)
The ability to change coloration allows animals to modify their patterning to suit a specific function. Many freshwater fishes, for example, can appear cryptic by altering the dispersion of melanin pigment in the skin to ...
Deceived by stripes
(2016)
Conspicuous coloration, which presumably makes prey more visible to predators, has intrigued researchers for long. Contrastingly coloured, conspicuous striped patterns are common among lizards and other animals, but their ...
Coevolutionary interactions between farmers andmafia induce host acceptance of avian brood parasites
(2016)
Brood parasites exploit their host in order to increase their own fitness. Typically, this results in an arms race between parasite trickery and host defence. Thus, it is puzzling to observe hosts that accept parasitism ...
Dopamine regulates termite soldier differentiation through trophallactic behaviours
(2016)
Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic ...
Sexual selection of male parental care in giant water bugs
(2016)
Paternal care can be maintained under sexual selection, if it helps in attracting more mates. We tested the hypothesis in two giant water bug species,Appasus majorandAppasus japonicus, that male parental care is sexually ...
Shared Escovopsis parasites between leaf cutting and non leaf cutting ants in the higher attine fungus growing ant symbiosis
(2015)
Fungus-gardening (attine) ants grow fungus for food in protected gardens, which contain beneficial, auxiliary microbes, but also microbes harmful to gardens. Among these potentially pathogenic microorganisms, the most ...
Diversification rates and phenotypic evolution in venomous snakes
(2016)
The relationship between rates of diversification and of body size change (a common proxy for phenotypic evolution) was investigated across Elapidae, the largest radiation of highly venomous snakes. Time-calibrated ...
