Intraspecific body size determines isotopic trophic structure of a large river fish community

Journal of Animal Ecology, EarlyView.
The body size of individuals within species plays an important role in determining trophic structure, yet many ecological models and tests of theory assign species‐level values to define trophic position or niches. Such studies ignore potential ontogenetic or within species size‐based changes in consumer behaviour and trophic dynamics that can occur as

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

What are the consequences of water stress on the development of late postzygotic reproductive isolation in an orchid hybrid zone?

Plant Species Biology, EarlyView.
Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.
