Evidence for an Allee effect in a declining fur seal population

Rebecca Nagel, Claire Stainfield, Cameron Fox-Clarke, Camille Toscani, Jaume Forcada & Joseph Hoffman
Allee effects play an important role in the dynamics of many populations and can increase the risk of local extinction. However, some authors have questioned the weight of evidence for Allee effects in wild populations. We therefore exploited a natural experiment provided by two adjacent breeding colonies of contrasting density to investigate the potential for Allee effects in an Antarctic fur seal (Arctocephalus gazella) population that is declining in response to climate-change induced reductions in...

Data from: Evidence of female preference for odour of distant over local males in a bat with female dispersal

Karin Schneeberger, Michael Schulze, Ingo Scheffler & Barbara Caspers
Geographic variation of sexual selected male traits is common in animals. Female choice also varies geographically and several studies found female preference for local males, which is assumed to lead to local adaptation and therefore increases fitness. As females are the non-dispersing sex in most mammalian taxa, this preference for local males might be explained by learning of male characteristics. Studies on preference of females in female-dispersing species are lacking so far. To find out...

Data from: High heritability of telomere length and low heritability of telomere shortening in wild birds

Christina Bauch, Jelle J. Boonekamp, Peter Korsten, Ellis Mulder & Simon Verhulst
Telomere length and telomere shortening predict survival in many organisms. This raises the question of the contribution of genetic and environmental effects to variation in these traits, which is still poorly known, particularly for telomere shortening. We used experimental (cross-fostering) and statistical (quantitative genetic ‘animal’ models) means to disentangle and estimate genetic and environmental contributions to telomere length variation in pedigreed free-living jackdaws (Corvus monedula). Telomere length was measured twice in nestlings, at ages 4...

Sex roles in birds: influence of climate, life histories and social environment

Tamas Székely, András Liker, Gavin H. Thomas, Jan Komdeur, Oliver Krügger & Alejandro Gonzalez-Voyer
For detailed information concerning data collection please see Gonzalez-Voyer et al. Sex roles in birds: phylogenetic analyses of the influence of climate, life histories and social environment. Ecology Letters. Briefly, data on ecology, life histories and behaviour of birds were extracted from published literature. If several data were available for a given species, we included the ones that were extracted from breeding individuals or had larger sample sizes. The details regarding data processing are provided...

Supplementary files for: How can the MHC mediate social odor via the microbiota community? A deep dive into mechanisms

Nadine Schubert, Hazel J. Nichols & Jamie C. Winternitz
Genes of the major histocompatibility complex (MHC) have long been linked to odor signaling and recently researchers’ attention has focused on MHC structuring of microbial communities and how this may in turn impact odor. However, understanding of the mechanisms through which the MHC could affect the microbiota to produce a chemical signal that is both reliable and strong enough to ensure unambiguous transmission of behaviorally important information remains poor. This is largely because empirical studies...

Data from: A bird’s eye view on turbulence: Seabird foraging associations with evolving surface flow features

Lilian Lieber, Roland Langrock & William Alex Michael Nimmo-Smith
Understanding physical mechanisms underlying seabird foraging is fundamental to predict responses to coastal change. For instance, turbulence in the water arising from natural or anthropogenic structures can affect foraging opportunities in tidal seas. Yet, identifying ecologically important localised turbulence features (e.g. upwellings ~10-100 m) is limited by observational scale and this knowledge gap is magnified in volatile predators. Here, using a drone-based approach, we present the tracking of surface-foraging terns (143 trajectories belonging to three...

Data: Inbreeding in a dioecious plant has sex- and population origin-specific effects on its interactions with pollinators

Karin Schrieber, Sarah Catherine Paul, Levke Valena Höche, Andrea Cecilia Salas, Rabi Amalthea Aphrodite Didszun, Jakob Mössnang, Caroline Müller, Alexandra Erfmeier & Elisabeth Johanna Eilers
This Dataset supports the article "Inbreeding in a dioecious plant has sex- and population origin-specific effects on its interactions with pollinators", which is published in eLife. The study addresses the combined effects of inbreeding, plant sex and plant population origin on interactions among plants and their specialised pollinators. It contains data on various floral traits (spatial flower traits, flower colour traits, floral scent traits (floral VOC), floral rewards) as well as pollinator visitation rates. The...

Intergenerations effects of starvation on Athalia

Caroline Müller, Sarah Paul, Pragya Singh & Alice Dennis
Intergenerational effects, also known as parental effects in which the offspring phenotype is influenced by the parental phenotype, can occur in response to factors that occur not only in early but also in late parental life. However, little is known about how these parental life stage-specific environments interact with each other and with the offspring environment to influence offspring phenotypes, particularly in organisms that realize distinct niches across ontogeny. We examined the effects of parental...

Repositories for taxonomic data: Where we are and what is missing

Aurélien Miralles, Teddy Bruy, Katherine Wolcott, Mark Scherz, Dominik Begerow, Bank Beszteri, Michael Bonkowski, Janine Felden, Birgit Gemeinholzer, Frank Glaw, Frank Oliver Glöckner, Oliver Hawlitschek, Ivaylo Kostadinov, Tim Nattkemper, Christian Printzen, Jasmin Renz, Nataliya Rybalka, Marc Stadler, Tanja Weibulat, Thomas Wilke, Susanne Renner & Miguel Vences
Natural history collections are leading successful large-scale projects of specimen digitization (images, metadata, DNA barcodes), transforming taxonomy into a big data science. Yet, little effort has been directed towards safeguarding and subsequently mobilizing the considerable amount of original data generated during the process of naming 15–20,000 species every year. From the perspective of alpha-taxonomists, we provide a review of the properties and diversity of taxonomic data, assess their volume and use, and establish criteria for...

Bee diversity in island-like habitats (kettle holes) to assess connectivity in agricultural landscapes - Part 1 of data collection

Sissi Lozada-Gobilard
During June and July of 2017, wild bees were collected using color traps (blue, yellow and white pans) in small water bodies called kettle holes embedded in agricultural landscapes in the north of Germany. After all wild bees were identified to species level, from a subset of samples we measured the Intertegular distance ITD (distance between the wings) as body size and searched for functional traits regarding sociality (solitary, eusocial, parasitic) nesting type (below- or...

Gregarines modulate insect responses to sublethal insecticide residues

Caroline Müller, Marina Wolz, Alia Schrader & Eileen Whitelaw
Throughout their lifetime, insects face multiple environmental challenges that influence their performance. Gregarines are prevalent endoparasites in most invertebrates that affect the fitness of their hosts, but are often overlooked in ecological studies. Next to such biotic factors, a current common challenge is anthropogenic pollution with pesticides, which causes a major threat to non-target organisms that are readily exposed to lethal or sublethal concentrations. In a laboratory study, we investigated whether the presence of gregarines...

Exceptionally high apparent adult survival in three tropical species of plovers in Madagascar

William Jones, Luke Eberhart-Hertel, Robert Freckleton, Joseph Hoffmann, Oliver Krüger, Brett Sandercock, Orsolya Vincze, Sama Zefania & Tamás Székely
Adult survival is a key component of population dynamics and understanding variation in and the drivers of adult survival rates and longevity is critical for ecological and evolutionary studies, as well as for conservation biology and practice. Tropical species of landbirds are often selected to have higher adult survival due to high nest predation rates, but it is unclear if the same patterns occur in other avian lineages with different life history strategies. Here, we...
