Data from: How neighbourhood interactions control the temporal stability and resilience to drought of trees in mountain forests

Marion Jourdan, Georges Kunstler & Xavier Morin
1. Over the coming decades, the predicted increase in frequency and intensity of extreme events such as droughts is likely to have a strong effect on forest functioning. Recent studies have shown that species mixing may buffer the temporal variability of productivity. However, most studies have focused on temporal stability of productivity, while species mixing may also affect forest resilience to extreme events. Our understanding of mechanisms underlying species mixing effects on forest stability and...

Virus mediated trophic interactions between aphids and their natural enemies

Arnaud Sentis
Microbial endosymbionts alter the phenotype of their host which may have cascading effects at both population and community levels. However, we currently lack information on whether the effects of viruses on both host phenotypic traits and host population demography can modify interactions with upper trophic levels. To fill this gap, we investigated whether a prevalent densovirus infecting the aphid Myzus persicae (i.e., MpDNV) can modify trophic interactions between host aphids and their natural enemies (i.e.,...

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...

Caractérisation de la géochimie des interfaces nappe-rivière du bassin des Avenelles

Jean-Marie Mouchel, Stefany Rocha, Agnès Rivière & Gaëlle Talec
Les zones ripariennes sont le lieu d’une activité biogéochimique intense. Elles ont été largement étudiées dans les vallées alluviales où la perméabilité des milieux alluviaux est élevée. Dans le bassin de l’Orgeval, le ru des Avenelles n’est pas un cours d’eau alluvial, mais il traverse deux nappes (Brie et Champigny) et nous nous intéressons aux processus qui affectent la qualité de ’eau au travers de la zone riparienne lors des écoulements des sols et de...

Data from: Drying determines the temporal dynamics of stream invertebrate structural and functional beta diversity

Julie Crabot, Thibault Datry & Bertrand Launay
Assembly processes shaping ecological communities can vary over time following variations of environmental conditions at different scales. Such temporal dynamism is exacerbated by climate change and increasing extreme events, and recent evidence suggests that, in turn, community composition and functions can vary substantially. However, empirical relationships between the spatio-temporal dynamics of communities and that extreme events altering ecosystems are poorly investigated. We quantified the temporal dynamics of stream invertebrate communities over two years across 11...

How far do Asian hornbills disperse seeds?

Rohit Naniwadekar, Akanksha Rathore, Ushma Shukla, Saniya Chaplod & Aparajita Datta
Biotic seed dispersal of plants is a complex phenomenon that is influenced by multiple seed disperser species with implications for plant fitness and range expansions. While inter-species variation has been well-studied, the importance of incorporating intraspecific variation in seed dispersal is increasingly being acknowledged. We compared seed dispersal patterns of breeding and non-breeding great hornbills Buceros bicornis and a breeding wreathed hornbill Rhyticeros undulatus by combining data on fruiting tree visitations, gut passage time and...

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

Nadège C. Bonnot, Ophélie Couriot, Anne Berger, Francesca Cagnacci, Simone Ciuti, Johannes De Groeve, Benedikt Gehr, Marco Heurich, Petter Kjellander, Max Kröschel, Nicolas Morellet, Leif Sönnichsen & A.J. Mark Hewison
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...
