1. Long-tailed tits (Aegithalos caudatus) are a cooperatively breeding species in which helpers often invest effort in the provisioning of young that are not their own. 2. We quantified the lifetime reproductive success (LRS) and the individual [...]

1. Dispersal limitation is widely invoked to explain species coexistence and cooperation in the face of competition and cheating. However, empirical evidence from natural ecosystems for the stabilizing effect of space is sparse. 2. We use a Neot[...]

1. We have assessed how different host parameters affect species richness of flea assemblages using the independent contrasts method. Three groups of host parameters were examined. The first group included host body parameters (body size, basal [...]

1. Parasitism is a non-negligible cost of reproduction in wild organisms, and hosts are selected to partition resources optimally between current and future reproduction. While parents can compensate for the cost of parasitism by increasing thei[...]

1. The number of reproductive events per lifetime affects all levels of ecological complexity, including the structure and dynamics of species communities. Here we investigate a sexual parasite-host system with two water frog species of which on[...]

1. Home range size, spatial organization and territoriality of reproductive Arctic foxes were studied during the summer. The influence of spatial distribution and availability of the main prey was investigated in order to evaluate whether the sp[...]

1. Variance in competitive ability among males should lead to a corresponding skew in reproductive success. Atlantic salmon (Salmo salar) males form dominance hierarchies during spawning, such that the dominant individuals are predicted to reali[...]

1. The introduction of animals to novel environments has been used as a model system for investigating the factors affecting small populations during their initial period of establishment. Previous studies of introduction success in birds have i[...]

1. We studied the metapopulation dynamics and persistence of an extinction-prone predator-prey interaction. We show that the dynamics of the system are influenced by both stochastic and deterministic processes. 2. Using host-parasitoid metapopul[...]

1. Dispersers in heterogeneous habitat theoretically should target the habitat(s) where reproduction and survival (i.e. fitness) will be highest. However, the cues that dispersing animals respond to are not well understood: differences in habita[...]
