Seasonal dynamics and age structure of drifting cyprinid fishes: an interspecific comparison
Ecology of Freshwater Fish, 2007Abstract – We investigated interspecific differences in the downstream drift of seven species of young‐of‐the‐year cyprinids over a 2‐year period in two central European rivers, using a comparison of drifting fish with fish collected from nurseries at the same time and the same site as the drift samples. Species varied in the utilisation of the drift;

The causes of the diversity differences that are apparent across taxonomic groups in the tree of life remain a key question in biology. This question has been investigated from the perspective of antagonistic, competitive, and mutualistic interactions.

Taylor’s power law, i.e. that the slope for the increase in variance with mean population size is between 1 and 2 at a logarithmic scale, provides one of the few quantitative relationships in population ecology, yet the underlying ecological mechanisms are only poorly understood.

A key goal of functional ecology is identifying relationships between species traits and environmental conditions. Here, the nature and significance of these relationships to community composition on long ecological timescales is investigated using paleoecological and paleoenvironmental data from coastal British Columbia, Canada.

Mercury (Hg) biomonitoring requires a precise understanding of the internal processes contributing to disparities between the Hg sources in the environment and the Hg measured in the biota. In this study, we investigated the use of Hg stable isotopes to trace Hg accumulation in Adélie and emperor penguin chicks from four breeding colonies in Antarctica.

I investigated the interactions of intra— and interspecific competition with parasitism for populations of two terrestrial isopods, Porcellio scaber and Porcellio laevis, infected with a lethal virus. In field experiments, I varied densities of one or both isopod species in enclosures in which food and virus presence were also manipulated.
