Humans have devised fishing technologies that compete with marine predators for fish resources world-wide. One such fishery for the Patagonian toothfish (Dissostichus eleginoides) has developed interactions with a range of predators, some of which are marine mammals capable of diving to extreme depths for extended periods. A deep-sea camera system deployed within a toothfish fishery operating i...

Mutual policing is an important mechanism for maintaining social harmony in group-living organisms. In some ants, bees, and wasps, workers police male eggs laid by other workers in order to maintain the reproductive primacy of the queen. Kin selection theory predicts that multiple mating by the queen is one factor that can selectively favor worker policing. This is because when the queen is mat...

It has been recognised for some years that animals differ consistently in various aspects of their behaviour, a phenomenon that has come to be referred to as animal personality. Recent work has attempted to investigate the ecological factors that shape personality, including the forms of stress that affect its expression. One of these – disease – is known to exert a considerable effect on host ...

Different methods are available to estimate the wildlife population development. In this paper a method based on hunter surveys of a Spanish game preserve is proposed. A Poisson model is fitted to estimate the relationship between hunting success and other independent variables. In order to find the most appropriate model, a model selection procedure based on repeated cross validation is used t...

The relative importance of bottom-up or top-down forces has been mainly studied for herbivores but rarely for pollinators. Habitat fragmentation might change driving forces of population dynamics by reducing the area of resource-providing habitats, disrupting habitat connectivity, and affecting natural enemies more than their host species. We studied spatial and temporal population dynamics of ...
