1. Although the quantification of individual heterogeneity in wild populations' vital rates has recently attracted growing interest among ecologists, the investigation of its evolutionary consequences remains limited, mainly because of the diffi[...]

1. A trophic cascade occurs when predators directly decrease the densities, or change the behaviour, of herbivores and thus indirectly increase plant productivity. The predator-herbivore-plant context is well known, but some predators attack spe[...]

1. Research concerning spatial dynamics of biodiversity generally has been limited to considerations of the taxonomic dimension, which is insensitive to interspecific variation in ecological or evolutionary characteristics that play important ro[...]

Heterogeneous hosts: how variation in host size, behaviour and immunity affects parasite aggregation
Pieter T. J. Johnson, Auteur ;
Jason T. Hoverman, Auteur
1. Infection heterogeneity is one of the most fundamental patterns in disease ecology, yet surprisingly few studies have experimentally explored its underlying drivers. Here, we used largescale field assessments to evaluate the degree of parasit[...]

1. Parasites are thought to have numerous negative effects on their hosts. These negative effects may be associated with stress in a host. 2. We evaluated the effects of four species of flea ectoparasites (Parapulex chephrenis, Synosternus cleop[...]

1. Understanding the demographic response of free-living animal populations to different drivers is the first step towards reliable prediction of population trends. 2. Penguins have exhibited dramatic declines in population size, and many studie[...]

1. How the environment influences the transmission and prevalence of disease in a population of hosts is a key aspect of disease ecology. The role that environmental factors play in host-pathogen systems has been well studied at large scales, th[...]

1. Landscapes in nature can be viewed as a continuum of small total habitable area with high fragmentation to widely spreading habitats. The dispersal-mediated rescue effect predominates in the former landscapes, while classical density-dependen[...]

1. Animal migrations are spectacular and migratory species have been shown to transmit pathogens that pose risks to human health. Although migration is commonly assumed to enhance pathogen dispersal, empirical work indicates that migration can o[...]
