Data from: Wood-inhabiting fungi with tight associations with other species have declined as a response to forest management

Nerea Abrego, David Dunson, Panu Halme, Isabel Salcedo & Otso Ovaskainen
Research on mutualistic and antagonistic networks, such as plant–pollinator and host–parasite networks, has shown that species interactions can influence and be influenced by the responses of species to environmental perturbations. Here we examine whether results obtained for directly observable networks generalize to more complex networks in which species interactions cannot be observed directly. As a case study, we consider data on the occurrences of 98 wood-inhabiting fungal species in managed and natural forests. We specifically...

Data from: Grazing exclusion unleashes competitive plant responses in Iberian Atlantic mountain grasslands

Iñaki Odriozola, Gonzalo García-Baquero, Marie-Josée Fortin, Nere Amaia Laskurain & Arantza Aldezabal
Questions: Does the absence of equalizing mechanisms after cessation of grazing unleash strong aboveground competitors to create large patches in the community? Do these competitive intraspecific aggregations displace and exclude other species, thereby reducing species diversity? Location: Atlantic grasslands in the Aralar Natural Park, Basque Country, Northern Iberian Peninsula. Methods: Large herbivores were experimentally excluded from three sites (50 m × 50 m exclusion fences) during nine years in a productive semi-natural grassland system with...

Data from: 18S rRNA V9 metabarcoding for diet characterization: a critical evaluation with two sympatric zooplanktivorous fish species

Aitor Albaina, Mikel Aguirre, David Abad, María Santos & Andone Estonba
The potential of the 18S rRNA V9 metabarcoding approach for diet assessment was explored using MiSeq paired-end (PE; 2 × 150 bp) technology. To critically evaluate the method′s performance with degraded/digested DNA, the diets of two zooplanktivorous fish species from the Bay of Biscay, European sardine (Sardina pilchardus) and European sprat (Sprattus sprattus), were analysed. The taxonomic resolution and quantitative potential of the 18S V9 metabarcoding was first assessed both in silico and with mock...

Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global study

Luz Boyero, Richard Pearson, Cang Hui, Mark Gessner, Javier Perez, Markos Alexandrou, Manuel Graça, Bradley Cardinale, Ricardo Albariño, M. Arunachalam, Leon Barmuta, Andrew Boulton, Andreas Bruder, Marcos Callisto, Eric Chauvet, Russell Death, David Dudgeon, Andrea Encalada, Veronica Ferreira, Ricardo Figueroa, Alex Flecker, , Julie Helson, Tomoya Iwata, Tajang Jinggut … & Catherine Yule
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of different drivers of plant litter breakdown in fresh waters, particularly at large scales. We present a global-scale study of litter breakdown in streams to compare the roles of biotic, climatic and...

Data from: The context dependence of assortative mating: a demonstration with conspecific salmonid populations

Zoé Gauthey, Andrew P. Hendry, Arturo Elosegi, Cédric Tentelier & Jacques Labonne
Assortative mating is thought to play a key role in reproductive isolation. However, most experimental studies of assortative mating do not take place in multiple natural environments and, hence, they ignore its potential context dependence. We implemented an experiment in which two populations of brown trout (Salmo trutta) with different natural flow regimes were placed into semi-natural stream channels under two different artificial flow regimes. Natural reproduction was allowed and reproductive isolation was measured by...
