The importance of environmental difference among sites and dispersal limitations of species to the explanation of diversity differs among biological systems and geographical regions. We hypothesized that climate and then dispersal limitation will predominantly explain the similarity of alpine vegetation at increasing distances between pairs of regions at sub-continental extent. We computed the similarity of all pairs of 23 European mountain regions below 50°N after dividing the species lists of each region by calcareous or...
1) The diversity of traits within animal assemblages has been shown to affect the magnitude of animal-provided ecological functions. However, little is known about how consistent trait diversity effects are across ecological functions and ecosystems. More importantly, the importance of trait diversity in driving ecosystem functioning, relative to other components of biodiversity, has rarely been assessed. It also remains unclear how environmental gradients filter trait diversity and, ultimately, modulate ecological functions. 2) Here we test...
Within the northern European Cochlearia (Brassicaceae), considerable chromosome variation has taken place without corresponding morphological differentiation, which has resulted in an intricate species complex including two base chromosome numbers and several ploidy levels. Here, we dig into the situation in Iceland. The distribution, genetic structure, taxonomy and origin of the two Cochlearia cytotypes (2n = 12 and 2n = 14) present in Iceland are discussed. Chromosome counts indicate that the 2n = 12 populations are...
Host identity matters – up to a point: the community context of Batrachochytrium dendrobatidis transmissionDavid Daversa, Jaime Bosch, Andy Fenton, Andrea Manica & Trent Garner
The level of detail on host communities needed to understand multi-host parasite invasions is an unresolved issue in disease ecology. Coarse community metrics that ignore functional differences between hosts, like host species richness, can be good predictors of invasion outcomes. Yet, if host species vary in the extent to which they maintain and transmit infections, then explicitly accounting for those differences may be important. Through controlled mesocosm experiments and modelling, we show that interspecific differences...
Variation and correlation in the timing of breeding of North Atlantic seabirds across multiple scalesKatharine Keogan, Francis Daunt, Sarah Wanless, Richard Phillips, David Alvarez, Tycho Anker-Nilssen, Robert Barrett, Claus Bech, Peter Becker, Per-Arvid Berglund, Sandra Bouwhuis, Zofia Burr, Olivier Chastel, Signe Christensen-Dalsgaard, Sébastien Descamps, Tony Diamond, Kyle Elliott, Kjell Einar Erikstad, Mike Harris, Jonas Hentati-Sundberg, Martin Heubeck, Magdalene Langset, Svein Lorentsen, Heather Major, Mark Mallory … & Stephen Kress
Timing of breeding, an important driver of fitness in many populations, is widely studied in the context of global change, yet despite considerable efforts to identify environmental drivers of seabird nesting phenology, for most populations we lack evidence of strong drivers. Here we adopt an alternative approach, examining the degree to which different populations positively covary in their annual phenology to infer whether phenological responses to environmental drivers are likely to be (i) shared across...
Understanding the mechanisms and genes that enable animal populations to adapt to pathogens is important from an evolutionary, health and conservation perspective. Berthelot’s pipit (Anthus berthelotii) experiences extensive and consistent spatial heterogeneity in avian pox infection pressure across its range of island populations, thus providing an excellent system with which to examine how pathogen-mediated selection drives spatial variation in immunogenetic diversity. Here we test for evidence of genetic variation associated with avian pox at both...
Dataframe from: Diversity of European habitat types is correlated with geography more than climate and human pressureMarco Cervellini, Michele Di Musciano, Piero Zannini, Simone Fattorini, Borja Jiménez-Alfaro, Emiliano Agrillo, Fabio Attorre, Pierangela Angelini, Carl Beierkuhnlein, Laura Casella, Richard Field, Jan-Christopher Fischer, Piero Genovesi, Samuel Hoffmann, Severin D.H. Irl, Juri Nascimbene, Duccio Rocchini, Manuel Steinbauer, Ole R. Vetaas & Alessandro Chiarucci
We generated this dataframe to model EU habitat richness at continental scale as a function of geographical, climate and anthropogenic variables (please, see Material and Method section in the published paper version for all the details). We found geographical variables were by far the most strongly correlated with habitat richness, followed by climate. However, anthropogenic variables gained importance when consindering their interactions, with important implications for conservation planning.
