Data from: Forgotten Mediterranean calving grounds of gray and North Atlantic right whales: evidence from Roman archaeological records

Ana S.L. Rodrigues, Anne Charpentier, Darío Bernal-Casasola, Armelle Gardeisen, Carlos Nores, José Antonio Pis Millán, Krista McGrath, Camilla F. Speller & Ana S. L. Rodrigues
Right whales (Eubalaena glacialis) were extirpated from the eastern North Atlantic by commercial whaling. Gray whales (Eschrichtius robustus) disappeared from the entire North Atlantic in still-mysterious circumstances. Here we test the hypotheses that both of these species previously occurred in the Mediterranean Sea, an area not currently considered part of their historical range. We used ancient DNA barcoding and collagen fingerprinting methods to taxonomically identify a rare set of 10 presumed whale bones from Roman...

Data from: Why do top predators engage in superpredation? From an empirical scenario to a theoretical framework

Rui Lourenço, Maria Del Mar Delgado, Letizia Campioni, Fernando Goytre, João E. Rabaça, Erkki Korpimäki & Vincenzo Penteriani
Lethal interactions can shape ecosystem structure, and consequently understanding their causes is ecologically relevant. To improve both empirical and theoretical knowledge on superpredation (i.e. predation on high-order predators), we studied an eagle owl population, including its main prey and mesopredators, and then we crossed these results with existing theories to provide a reasoning framework. We fitted our field data into four main causes explaining lethal interactions: food stress, opportunistic superpredation, removal of a competitor, and...

Data from: Hindered and constrained: limited potential for thermal adaptation in post-metamorphic and adult Rana temporaria along elevational gradients

Urtzi Enriquez-Urzelai, Antonio S. Palacio, Natalia M. Merino, Martina Sacco & Alfredo G. Nicieza
Adaptation to warming climates could counteract the effects of global warming. Thus, understanding how species cope with contrasting climates may inform us about their potential for thermal adaptation and which processes may hamper that ability (e.g. evolutionary trade-offs, phenology, or behavioural thermoregulation). In addition to temperature, time constraints may also exert important selective pressures. Here we compare the thermal sensitivity of locomotion of metamorphic and adult European common frogs (Rana temporaria) originating from populations along...

Data from: Management trade-offs on ecosystem services in apple orchards across Europe: direct and indirect effects of organic production

Ulrika Samnegard, Georgina Alins, Virginie Boreux, Jordi Bosch, Daniel García, Anne-Kathrin Happe, Alexandra Klein, Marcos Miñarro, Karsten Mody, Mario Porcel, Anselm Rodrigo, Laura Roquer-Beni, Marco Tasin, Peter A. Hambäck & Alexandra-Maria Klein
1. Apple is considered the most important fruit crop in temperate areas and profitable production depends on multiple ecosystem services, including the reduction of pest damage and the provision of sufficient pollination levels. Management approaches present an inherent trade-off as each affects species differently. 2. We quantified the direct and indirect effects of management (organic versus integrated pest management (IPM)) on species richness, ecosystem services and fruit production in 85 apple orchards in three European...

Data from: Ecological and evolutionary drivers of the elevational gradient of diversity

Paola Laiolo, Joaquina Pato & J R Obeso
Ecological, evolutionary, spatial and neutral theories make distinct predictions and provide distinct explanations for the mechanisms that control the relationship between diversity and the environment. Here, we test predictions of the elevational diversity gradient focusing on Iberian bumblebees, grasshoppers and birds. Processes mediated by local abundance and regional diversity concur in explaining local diversity patterns along elevation. Effects expressed through variation in abundance were similar among taxa and point to the overriding role of a...

Data from: Frugivore biodiversity and complementarity in interaction networks enhance landscape-scale seed dispersal function

Daniel García, Isabel Donoso & Javier Rodríguez-Pérez
1. Animal biodiversity matters for the provision of ecosystem functions derived from trophic activity. However, the mechanisms underlying this pattern remain elusive since animal abundance and diversity, which are the components commonly used for representing biodiversity, provide poor information about ecological complementarity in species assemblages. An approach based on species interaction networks may overcome this constraint. 2. Here, we relate frugivore biodiversity and frugivore-plant network structure with landscape-scale seed dispersal function. We sampled, for two...

Data from: Association mapping reveals candidate loci for resistance and anemic response to an emerging temperature-driven parasitic disease in a wild salmonid fish

Freed Ahmad, Paul Debes, Gemma Palomar & Anti Vasemägi
Even though parasitic infections are often costly or deadly for the host, we know very little which genes influence parasite susceptibility and disease severity. Proliferative kidney disease (PKD) is an emerging and, at elevated water temperatures, potentially deadly disease of salmonid fishes that is caused by the myxozoan parasite Tetracapsuloides bryosalmonae. By screening > 7.6 K SNPs in 255 wild brown trout (Salmo trutta) and combining association mapping and random forest approaches, we identified several...

Data from: The influence of distance to perennial surface water on ant communities in Mopane woodlands, northern Botswana

Fredrik Dalerum, Tarryn Anne Retief, Carl Peter Havemann, Christian T. Chimimba, Benrdt Janse Van Rensburg & Berndt Janse Van Rensburg
Studies of biodiversity along environmental gradients provide information on how ecological communities change in response to biotic and abiotic factors. For instance, distance to water is associated with several factors that shape the structure and the functioning of ecosystems at a range of spatial scales. We investigated the influence of distance to a perennial water source on ant communities in a semi-arid savanna in northern Botswana. Ant abundance, taxonomic richness and both alpha and beta...

Data from: Moving from frugivory to seed dispersal: incorporating the functional outcomes of interactions in plant-frugivore networks

Benno I. Simmons, William J. Sutherland, Lynn V. Dicks, Jörg Albrecht, Nina Farwig, Daniel Garcia, Pedro Jordano & Juan P. González-Varo
1.There is growing interest in understanding the functional outcomes of species interactions in ecological networks. For many mutualistic networks, including pollination and seed dispersal networks, interactions are generally sampled by recording animal foraging visits to plants. However, these visits may not reflect actual pollination or seed dispersal events, despite these typically being the ecological processes of interest. 2.Frugivorous animals can act as seed dispersers, by swallowing entire fruits and dispersing their seeds, or as pulp...
