1. Understanding the trade-off between current reproductive effort, future survival and future breeding attempts is crucial for demographic analyses and life history studies. 2. We investigated this trade-off in a population of king penguins (Ap[...]

1. Climate change could affect resource competition between resident and migratory bird species by changing the interval between their onsets of breeding or by altering their population densities. 2. We studied interspecific nest-hole competitio[...]

1. Humans are increasingly influencing global climate and regional predator assemblages, yet a mechanistic understanding of how climate and predation interact to affect fluctuations in prey populations is currently lacking. 2. Here we develop a [...]

1. Much of the literature on the relationship between species richness or functional group richness and measures of ecosystem function focuses on a restricted set of ecosystem function measures and taxonomic groups. Few such studies have been ca[...]

1. We examined the relative contributions of regional spatial characteristics and local environmental conditions in determining Paraguayan bat species composition. 2. We used a suite of full and partial redundancy analyses to estimate four addit[...]
