Disease-limited distributions? Contrasts in the prevalence of avian malaria in shorebird species using marine and freshwater habitats

Article Abstract:

The new polymerase chain reaction (PCR)-based assays are capitalized and the hypothesis that inland wintering shorebirds of freshwater habitats run higher risks of infection by vector-borne blood parasites of the genera 'Plasmodium' and 'Haemoproteus' than similar species using marine habitats is tested. The test is based on an extensive survey of avian malaria infections in shorebirds from different habitat types at different latitudes.

A comment on Hubbell's zero-sum ecological drift model

Article Abstract:

Hubbell's zero-sum model enables ecologists to take a quantitative look at communities over varied scales of time and space. However, external factors such as changing environments shape community composition more rapidly and powerfully than stochastic processes.

Carrying capacity models should not use fixed prey density thresholds: a plea for using more tools of behavioural ecology

Article Abstract:

The existing rate-maximizing models are changed into fitness-maximizing models. The empirical studies on estimation of carrying capacity are discussed.
