Data from: Variable outcomes of hybridization between declining Alosa alosa and Alosa fallax

Olivier Lepais, Laura Taillebois, Stephen Sabatino, Aurélie Manicki, Françoise Daverat & David José Nachon
Hybridization dynamics between co-occurring species in environments where human-mediated changes take place is important to quantify for furthering our understanding of human impacts on species evolution and for informing management. The allis shad Alosa alosa (Linnaeus, 1758) and twaite shad Alosa fallax (Lacépède, 1803), two clupeids sister species, have been severely impacted by human activities across Europe. The shrinkage of A. alosa distribution range along with the decline of the remaining populations’ abundance threaten its...

Opposite latitudinal patterns for bird and arthropod predation revealed in the experiments with differently colored artificial prey

The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed...

Data from: Fear of the dark? contrasting impacts of humans vs lynx on diel activity of roe deer across Europe

Humans, as super predators, can have strong effects on wildlife behaviour, including profound modifications of diel activity patterns. Subsequent to the return of large carnivores to human-modified ecosystems, many prey species have adjusted their spatial behaviour to the contrasting landscapes of fear generated by both their natural predators and anthropogenic pressures. The effects of predation risk on temporal shifts in diel activity of prey, however, remain largely unexplored in human-dominated landscapes. We investigated the influence...

Data from: Assessing the effects of quantitative host resistance on the life-history traits of sporulating parasites with growing lesions

Melen Leclerc, Julie Clément, Didier Andrivon & Frédéric Hamelin
Assessing life-history traits of parasites on resistant hosts is crucial in evolutionary ecology. In the particular case of sporulating pathogens with growing lesions, phenotyping is difficult because one needs to disentangle properly pathogen spread from sporulation. By considering Phytophthora infestans on potato, we use mathematical modelling to tackle this issue and refine the assessment pathogen response to quantitative host resistance. We elaborate a parsimonious leaf-scale model by convolving a lesion growth model and a sporulation...

Data from: Leaf drought tolerance cannot be inferred from classic leaf traits in a tropical rainforest

Isabelle Maréchaux, Laurent Saint-André, Megan K. Bartlett, Lawren Sack & Jérôme Chave
Plants are enormously diverse in their traits and ecological adaptation, even within given ecosystems, such as tropical rainforests. Accounting for this diversity in vegetation models poses serious challenges. Global plant functional trait databases have highlighted general trait correlations across species that have considerably advanced this research program. However, it remains unclear whether trait correlations found globally hold within communities, and whether they extend to drought tolerance traits. For 134 individual plants spanning a range of...
