Grossman, Kalsum M. Yusah, Sarah H. Luke, Renata Pacheco, Jessica Pearce-Duvet, Javier Retana, Melanie Tista, Catherine L. Parr & H. L. Vasconcelos
Global extinction drivers, including habitat disturbance and climate change, are thought to affect larger species more than smaller species. However, it is unclear if such drivers interact to affect assemblage body size distributions. We asked how these two key global change drivers differentially affect the interspecific size distributions of ants, one of the most abundant and ubiquitous animal groups on earth. We also asked whether there is evidence of synergistic interactions and whether effects are...

Data from: Contrasting habitat and landscape effects on the fitness of a long-lived grassland plant under forest encroachment: do they provide evidence for extinction debt?

Guillem Bagaria, Ferran Rodà, Maria Clotet, Silvia Míguez & Joan Pino
1. Habitat loss, fragmentation and transformation threaten the persistence of many species worldwide. Population and individual fitness are often compromised in small, degraded and isolated habitats, but extinction can be a slow process and extinction debts are common. 2. Long-lived species are prone to persist as remnant populations in low quality habitats for a long time, but the population and individual-level mechanisms of extinction debt remain poorly explored so far. 3. We here investigate the...

Data from: Taxonomic and functional ant diversity along a secondary successional gradient in a tropical forest

Maya Rocha-Ortega, Xavier Arnan, José Domingos Ribeiro-Neto, Inara R. Leal, Mario E. Favila & Miguel Martínez-Ramos
The taxonomic diversity (TD) of tropical flora and fauna tends to increase during secondary succession. This increase may be accompanied by changes in functional diversity (FD), although the relationship between TD and FD is not well understood. To explore this relationship, we examined the correlations between the TD and FD of ants and forest age in secondary forests at the α- and β-diversity levels using single- and multi-trait-based approaches. Our objectives were to understand ant...

Data from: Isotopic methods for non-destructive assessment of carbon dynamics in shrublands under long-term climate change manipulation

Louise C. Andresen, Maria T. Dominguez, Sabine Reinsch, Andy R. Smith, Inger Kappel Schmidt, Per Ambus, Claus Beier, Pascal Boeckx, Roland Bol, Giovanbattista De Dato, Bridget A. Emmett, Marc Estiarte, Mark H. Garnett, György Kröel-Dulay, Sharon L. Mason, Cecilie S. Nielsen, Josep Penuelas, Albert Tietema & Andrew R. Smith
1.Long-term climate change experiments are extremely valuable for studying ecosystem responses to environmental change. Examination of the vegetation and the soil should be non-destructive to guarantee long-term research. In this paper, we review field methods using isotope techniques for assessing carbon dynamics in the plant-soil-air continuum, based on recent field experience and examples from a European climate change manipulation network. 2.Eight European semi-natural shrubland ecosystems were exposed to warming and drought manipulations. One field site...

Data from: Abrupt changes in the composition and function of fungal communities along an environmental gradient in the High Arctic

Grau Oriol, Jozsef Geml, Aaron Pérez-Haase, Josep M. Ninot, Tatiana A. Semenova-Nelsen, Josep Peñuelas & Oriol Grau
Fungi play a key role in soil-plant interactions, nutrient cycling, and carbon flow and are essential for the functioning of arctic terrestrial ecosystems. Some studies have shown that the composition of fungal communities is highly sensitive to variations in environmental conditions, but little is known about how the conditions control the role of fungal communities (i.e. their ecosystem function). We used DNA metabarcoding to compare taxonomic and functional composition of fungal communities along a gradient...

Data from: Generation and maintenance of predation hotspots of a functionally important herbivore in a patchy habitat mosaic

Simone Farina, Aitana Oltra, Jordi Boada, Frederic Bartumeus, Javier Romero & Teresa Alcoverro
1. By modifying how critical ecosystem functions are distributed across the landscape, the spatial configuration and characteristics of patches can play a strong role in structuring communities. In strongly predator-controlled ecosystems, this patchy distribution of function can have complex downstream consequences, subjecting some areas to disproportionately high rates of predation, leaving other areas susceptible to herbivore outbreaks. 2. In this study we assess how spatial attributes at patch and landscape scales potentially influence the spatial...

Data from: Multiple interaction networks: towards more realistic descriptions of the web of life

David García-Callejas, Roberto Molowny-Horas & Miguel Araújo
Ecological communities are defined by species interacting dynamically in a given location at a given time, and can be conveniently represented as networks of interactions. Pairwise interactions can be ascribed to one of five main types, depending on their outcome for the species involved: amensalism, antagonism (including predation, parasitism and disease), commensalism, competition or mutualism. While most studies have dealt so far with networks involving one single type of interaction at a time, often focusing...

Data from: Relationship type affects the reliability of dispersal distance estimated using pedigree inferences in partially sampled populations: a case study involving invasive American mink in Scotland

Yolanda Melero, Matthew K. Oliver & X. Lambin
Estimating dispersal—a key parameter for population ecology and management—is notoriously difficult. The use of pedigree assignments, aided by likelihood-based software, has become popular to estimate dispersal rate and distance. However, the partial sampling of populations may produce false assignments. Further, it is unknown how the accuracy of assignment is affected by the genealogical relationships of individuals and is reflected by software-derived assignment probabilities. Inspired by a project managing invasive American mink (Neovison vison), we estimated...

Aboveground plant biomass and soil respiration for seven European shrublands under drought and warming manipulations (1998-2012)

S. Reinsch, E. Koller, A. Sowerby, G. De Dato, M. Estiarte, G. Guidolotti, E. Kovács-Láng, G Kröel-Dula, E. Lellei-Kovács, K.S. Larsen, D. Liberati, R Ogaya, J. Peñuelas, J. Ransijn, D.A. Robinson, I.K. Schmidt, A.R. Smith, A. Tietema, J.S. Dukes, C. Beier & B.A. Emmett
The data consists of annual measurements of standing aboveground plant biomass, annual aboveground net primary productivity and annual soil respiration between 1998 and 2012. Data were collected from seven European shrublands that were subject to the climate manipulations drought and warming. Sites were located in the United Kingdom (UK), the Netherlands (NL), Denmark ( two sites, DK-B and DK-M), Hungary (HU), Spain (SP) and Italy (IT). All field sites consisted of untreated control plots, plots...

Data from: Do asynchronies in extinction debt affect the structure of trophic networks? A case study of antagonistic butterfly larvae–plant networks

Moisès Guardiola, Constanti Stefanescu, Ferran Rodà & Joan Pino
Habitat loss and fragmentation affect species richness in fragmented habitats and can lead to immediate or time-delayed species extinctions. Asynchronies in extinction and extinction debt between interacting species may have severe effects on ecological networks. However, these effects remain largely unknown. We evaluated the effects of habitat patch and landscape changes on antagonistic butterfly larvae-plant trophic networks in Mediterranean grasslands in which previous studies had shown the existence of extinction debt in plants but not...
