The climate variability hypothesis posits that increased environmental thermal variation should promote species with broader thermal tolerance breadths, while stable environments should promote thermal specialists. This hypothesis has been tested on large spatial scales, such as latitude and elevation, but less so on smaller scales which reflect the experienced microclimate. Here, we estimated thermal tolerance limits of 75 species of amphibian tadpoles from an aseasonal tropical mountain range of the Ecuadorian Andes, distributed along a...
Large-scale ecological restoration is crucial for effective biodiversity conservation and combating climate change. However, perspectives on the goals and values of restoration are highly diverse, as are the different approaches to restoration e.g., ranging from the restoration of cultural ecosystems to rewilding. We assess how the future of nature is envisioned in participatory scenarios, focusing on which elements of rewilding and nature contributions to people have been considered in scenario narratives across Europe. We use...
Ecological restoration of aquatic ecosystems has become widespread in recent decades. Whereas the recovery of biodiversity in restored wetlands has been studied from a taxonomic perspective, our knowledge of how functional biodiversity recovers remains poorly understood. We studied the functional diversity of macroinvertebrate communities in 32 Mediterranean temporary ponds six to seven years after their creation during a restoration in South-West Spain, and compared them with 10 natural reference sites during two consecutive hydroperiods. We...
Data supporting: Drivers of individual-based, antagonistic interaction networks during plant range expansionJorge Isla, Miguel Jácome-Flores, Pareja Daniel & Jordano Pedro
1. Range expansion in plant populations, especially at the colonization front, can be either limited by disproportionately large effects of antagonistic interactions or facilitated by their release. How the strength of antagonistic interactions changes along successional gradients during range expansion is still poorly documented, especially when diverse assemblages of plant antagonists (rodents, invertebrates, and birds) combine within interaction networks. 2. We study the changes in individual-based, predispersal seed-pulp predator networks along a colonization gradient in...
Post-divergence gene flow can trigger a number of creative evolutionary outcomes, ranging from the transfer of beneficial alleles across species boundaries (i.e., adaptive introgression) to the formation of new species (i.e., hybrid speciation). While neutral and adaptive introgression has been broadly documented in nature, hybrid speciation is assumed to be rare and the evolutionary and ecological context facilitating this phenomenon still remains controversial. Through combining genomic and phenotypic data, we evaluate the hypothesis that the...
Hotspots in the grid: Avian sensitivity and vulnerability to collision risk from energy infrastructure interactions in Europe and North AfricaJethro George Gauld, João P. Silva, Philip W. Atkinson, Paul Record, Marta Acácio, Volen Arkumarev, Julio Blas, Willem Bouten, Niall Burton, Inês Catry, Jocelyn Champagnon, Elizabeth A. Masden, Gary D. Clewley, Mindaugas Dagys, Olivier Duriez, Klaus‐Michael Exo, Wolfgang Fiedler, Andrea Flack, Guilad Friedemann, Johannes Fritz, Clara García-Ripollés, Stefan Garthe, Dimitri Giunchi, Atanas Grozdanov, Roi Harel … & Victoria Saravia
1. Wind turbines and power lines can cause bird mortality due to collision or electrocution. The biodiversity impacts of energy infrastructure (EI) can be minimised through effective landscape-scale planning and mitigation. The identification of high-vulnerability areas is urgently needed to assess potential cumulative impacts of EI while supporting the transition to zero-carbon energy. 2. We collected GPS location data from 1,454 birds from 27 species susceptible to collision within Europe and North Africa and identified...
Spatio-temporal dynamics of genetic variation at the quantitative and molecular levels within a natural Arabidopsis thaliana populationXavier Picó
Evolutionary change begins at the population scale. Therefore, understanding adaptive variation requires the identification of the factors maintaining and shaping standing genetic variation at the within-population level. Spatial and temporal environmental heterogeneity represent ecological drivers of within-population genetic variation, determining the evolutionary trajectory of populations along with random processes. Here, we focused on the effects of spatio-temporal heterogeneity on quantitative and molecular variation in a natural population of the annual plant Arabidopsis thaliana. We sampled...
The ability of a species to cope with both long-term and short-term environmental fluctuations might vary with the species' life history. While some life-history characteristics promote large and stable population sizes despite interannual environmental fluctuations, other life-history strategies might allow to evolve quickly in response to long-term gradual changes. In a theoretical study, we show that there is a tradeoff between both properties. Life-history characteristics that promote fast rates of evolution come at the expense...
Broad-scale patterns of geographic avoidance between species emerge in the absence of fine-scale mechanisms of coexistenceRoberto Novella-Fernandez, Javier Juste, Carlos Ibanez, Hugo Rebelo, Danilo Russo, Antton Alberdi, Andreas Kiefer, Laura Graham, Patrick Doncaster, Hynek Paul & Orly Razgour
Aim: The need to forecast range shifts under future climate change has motivated an increasing interest in better understanding the role of biotic interactions in driving diversity patterns. The contribution of biotic interactions to shaping broad-scale species distributions is however, still debated, partly due to the difficulty of detecting their effects. We aim to test whether spatial exclusion between potentially competing species can be detected at the species range scale, and whether this pattern relates...
Evolutionary consequences of pesticide exposure include transgenerational plasticity and potential terminal investment transgenerational effectsVerónica Castaño-Sanz, Ivan Gomez-Mestre & Francisco Garcia-Gonzalez
Transgenerational plasticity, the influence of the environment experienced by parents on the phenotype and fitness of subsequent generations, is being increasingly recognised. Human-altered environments, such as those resulting from the increasing use of pesticides, may be major drivers of such cross-generational influences, which in turn may have profound evolutionary and ecological repercussions. Most of these consequences are, however, unknown. Whether transgenerational plasticity elicited by pesticide exposure is common, and the consequences of its potential carry-over...
