Drivers of alloparental provisioning of fledglings in a colonially-breeding bird

Mina Ogino, Adriana Maldonado Chaparro & Damien Farine
Offspring provisioning represents a major reproductive cost. However, evidence suggests that parents sometimes feed unrelated offspring. Several hypotheses could explain this puzzling phenomenon. Adults could feed unrelated offspring that are (1) of close social associates to facilitate these juveniles’ integration into their social network (resulting in social inheritance), (2) potential extra-pair offspring, (3) at a similar developmental stage as their own, (4) coercing feeding by begging, or (5) less-developed and who’s enhanced survival would benefit...

Data from: How to make methodological decisions when inferring social networks

André Ferreira, Rita Covas, Liliana Silva, Sandra Esteves, Inês Duarte, Rita Fortuna, Franck Theron, Claire Doutrelant & Damien Farine
Social network analyses allow studying the processes underlying the associations between individuals and the consequences of those associations. Constructing and analysing social networks can be challenging, especially when designing new studies as researchers are confronted with decisions about how to collect data and construct networks, and the answers are not always straightforward. The current lack of guidance on building a social network for a new study system might lead researchers to try several different methods,...

Data from: First evidence of wasp brood development inside active nests of a termite with the description of a previously unknown potter wasp species

Helder Hugo, Marcel G. Hermes, Bolívar R. Garcete-Barrett & Iain D. Couzin
Potter wasps (Vespidae: Eumeninae) are known to exhibit not only sophisticated preying strategies but also a remarkable ability to manipulate clay during nest building. Due to a mixture of plasticity in building behaviour and flexibility in substrate preferences during nest-building, the group has been reported nesting in a variety of places, including decaying nests abandoned by termite species. Yet, evidence of wasps nesting inside senescent termite mounds is poorly reported and, to date, accounts confirming...

Individual variability and versatility in an eco-evolutionary model of avian migration

Benjamin M. Van Doren, Kira E. Delmore, Greg J. Conway, Teja Curk, Tania Garrido-Garduño, Ryan R. Germain, Timo Hasselmann, Dieter Hiemer, Henk Van Der Jeugd, Hannah Justen, Juan Sebastian Lugo Ramos, Ivan Maggini, Britta S. Meyer, Robbie J. Phillips, Magdalena Remisiewicz, Graham C. M. Roberts, Ben C. Sheldon, Wolfgang Vogl & Miriam Liedvogel
Seasonal migration is a complex and variable behavior with the potential to promote reproductive isolation. In Eurasian blackcaps (Sylvia atricapilla), a migratory divide in central Europe separating populations with southwest and southeast autumn routes may facilitate isolation, and individuals using new wintering areas in Britain show divergence from Mediterranean winterers. We tracked 100 blackcaps in the wild to characterize these strategies. Blackcaps to the west and east of the divide used predominantly SW and SE...

Nonaggressive behavior: A strategy employed by an obligate nest invader to avoid conflict with its host species

Helder Hugo, Paulo F. Cristaldo & Og DeSouza
In addition to its builders, termite nests are known to house a variety of secondary opportunistic termite species so‐called inquilines, but little is known about the mechanisms governing the maintenance of these symbioses. In a single nest, host and inquiline colonies are likely to engage in conflict due to nestmate discrimination, and an intriguing question is how both species cope with each other in the long term. Evasive behaviour has been suggested as one of...

Data for: Early-life behavior predicts first-year survival in a long-distance avian migrant

Shay Rotics, Martin Wikelski & Ran Nathan
Early-life conditions have critical, long-lasting effects on the fate of individuals, yet early-life activity has rarely been linked to subsequent survival of animals in the wild. Using high-resolution GPS and body-acceleration data of 93 juvenile white storks (Ciconia ciconia), we examined the links between behavior during both pre-fledging and post-fledging (fledging-to-migration) periods and subsequent first year survival. Juvenile daily activity (based on overall dynamic body acceleration) showed repeatable between-individual variation, the juveniles’ pre and post-fledging...

Metabolic rate in common shrews is unaffected by temperature, leading to lower energetic costs through seasonal size reduction

Paul Schaeffer, M. Teague O'Mara, Japhet Breiholz, Lara Keicher, Javier Lázaro, Marion Muturi & Dina Dechmann
Small endothermic mammals have high metabolisms, particularly at cold temperatures. In light of this, some species have evolved a seemingly illogical strategy: they reduce the size of the brain and several organs to become even smaller in winter. To test how this morphological strategy affects energy consumption across seasonally shifting ambient temperatures, we measured oxygen consumption and behaviour in the three seasonal phenotypes of the common shrew (Sorex araneus), which differ in size by about...

Data from: Socially foraging bats discriminate between group members based on search-phase echolocation calls

Jenna Kohles, Gerald Carter, Rachel A. Page & Dina Dechmann
Animals have evolved diverse strategies to use social information for increasing foraging success and efficiency. Echolocating bats, for example, can eavesdrop on bats foraging nearby, because they shift from search-phase calls to feeding buzzes when they detect prey. Feeding buzzes can directly convey information about prey presence, but it is unknown whether search-phase calls also convey social information. Here we investigated whether search-phase echolocation calls, distinct calls produced by some bat species to scan large...

Data set for: Behavioral traits that define social dominance are the same that reduce social influence in a consensus task

Alex Jordan
Dominant individuals are often most influential in their social groups, affecting movement, opinion, and performance across species and contexts. Yet behavioral traits like aggression, intimidation, and coercion, which are associated with and in many cases define dominance, can be socially aversive. The traits that make dominant individuals influential in one context may therefore reduce their influence in other contexts. Here we examine this association between dominance and influence using the cichlid fish Astatotilapia burtoni, comparing...

Effect of ecological factors on fine-scale patterns of social structure in African lions

Moreangels Mbizah, Damien Farine, Marion Valeix, Jane Hunt, David Macdonald & Andrew Loveridge
1. Environmental variations can influence the extent to which individuals interact with other individuals by changing the value of grouping. It is well known that many species can form and disband groups, often in response to the distribution and abundance of resources. 2. While previous studies showed that resources influence the broad-scale structure of animal groups, knowledge gaps remain on whether they affect fine-scale patterns of association among individuals within groups. 3. We quantify association...

Seasonal niche tracking of climate emerges at the population level in a migratory bird

Guillermo Fandos, Shay Rotics, Nir Sapir, Wolfgang Fiedler, Michael Kaatz, Martin Wikelski, Ran Nathan & Damaris Zurell
Seasonal animal migration is a widespread phenomenon. At the species level, it has been shown that many migratory animal species track similar climatic conditions throughout the year. However, it remains unclear whether such niche tracking pattern is a direct consequence of individual behaviour or emerges at the population or species level through behavioural variability. Here, we estimated seasonal niche overlap and seasonal niche tracking at the individual and population level of Central European White Storks...

Structural manipulations of a shelter resource reveal underlying preference functions in a shell-dwelling cichlid fish

Aneesh Bose, Johannes Windorfer, Alex Böhm, Fabrizia Ronco, Adrian Indermaur, Walter Salzburger & Alex Jordan
Many animals can modify the environments in which they live, thereby changing the selection pressures they experience. A common example of such niche-construction is the use, creation, or modification of environmental resources for use as nests or shelters. Because these resources often have correlated structural elements, it can be difficult to disentangle the relative contribution of these elements to resource choice, and the preference functions underlying niche-construction behaviour remain hidden. Here, we present an experimental...

Seasonal dietary niche contraction in coexisting Neotropical frugivorous bats (Stenodermatinae)

Jeremy Ryan Shipley & Cornelia Twining
Tropical dry forests are characterized by punctuated seasonal precipitation patterns that drive primary production and the availability of fruits, seeds, flowers, and insects throughout the year. In environments in which the quantity and quality of food resources varies seasonally, consumers should adjust their foraging behavior to maximize energy intake while minimizing overlap with competitors during periods of low food availability. Here, we investigated how the diets of frugivorous bats in tropical dry forests of NW...

Diurnal timing of nonmigratory movement by birds: the importance of foraging spatial scales

Julie Mallon, Marlee Tucker, Annalea Beard, , Keith Bildstein, Katrin Böhning-Gaese, John Brzorad, Evan Buechley, Javier Bustamante, Carlos Carrapato, José Castillo-Guerrero, Elizabeth Clingham, Mark Desholm, Christopher DeSorbo, Robert Domenech, Hayley Douglas, Olivier Duriez, Peter Enggist, Nina Farwig, Wolfgang Fiedler, Anna Gagliardo, Clara García-Ripollés, Juan Antonio Gil, Morgan Gilmour, Roi Harel … & Bill Fagan
Timing of activity can reveal an organism’s efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of timing of movement activity among species using six temporal variables: start of activity relative to sunrise, end of activity relative to...

The macroecology of reef fish agonistic behaviour

Luisa Fontoura, Mauricio Cantor, Guilherme Longo, Mariana Bender, Roberta Bonaldo & Sergio Floeter
Understanding the interplay between processes operating at large and small spatiotemporal scales in shaping biotic interactions within biological communities remains challenging. Recent studies illustrate how phenotypic specialization, species life-history traits and/or resource partitioning recurrently underlie the structure of mutualistic interactions in terrestrial ecosystems along large latitudinal gradients of biodiversity. However, we know considerably less about how local processes interact with large-scale patterns of biodiversity in modulating biotic interactions in the marine realm. Considering agonistic behaviour...

Congruent geographic variation in saccular otolith shape across multiple species of African cichlids

Aneesh Bose, Holger Zimmermann, Georg Winkler, Alexandra Kaufmann, Thomas Strohmeier, Stephan Koblmüller & Kristina Sefc
The otoliths of teleost fishes exhibit a great deal of inter- and intra-species shape variation. The ecomorphology of the saccular otolith is often studied by comparing its shape across species and populations inhabiting a range of environments. However, formal tests are often lacking to examine how closely variation in otolith shape follows the genetic drift of a neutral trait. Here, we examine patterns of saccular otolith shape variation in four species of African cichlid fishes,...

Data from - Ecological insights from three decades of animal movement tracking across a changing Arctic

Gil Bohrer, Sarah Davidson, Eliezer Gurarie, Scott LaPoint, Peter Mahoney, Emma Grier, Ophélie Couriot, Allicia Kelly, Bryan Bedrosian, Jerrold Belant, Travis Booms, Bridget Borg, Stan Boutin, Erica Craig, Tracy Davison, Robert Domenech, James Hodson, Kyle Joly, Nicholas Larter, A. David M. Latham, Stephen Lewis, Carol McIntyre, Tricia Miller, Kelsey Russell, Dale Seip … & Judy Williams
We provide here the data used in analysis of 3 test cases, presented in the manuscript "Ecological insights from three decades of animal movement tracking across a changing Arctic". We utilized the new Arctic Animal Movement Archive (AAMA), a growing collection of 201 standardized terrestrial and marine animal tracking studies from 1991–present. The AAMA supports public data discovery, preserves fundamental baseline data for the future, and facilitates efficient, collaborative data analysis. With three AAMA-based case...

Primary data on skull and brain morphology for: Geographical patterns in seasonal changes of body mass, skull, and brain size of common shrews

Javier Lázaro, Lucie Nováková, Moritz Hertel, Jan R. E. Taylor, Marion Muturi, Karol Zub & Dina K. N. Dechmann
Some small mammals exhibit Dehnel’s Phenomenon, a drastic decrease in body mass, braincase and brain size from summer to winter, followed by regrowth in spring. This is accompanied by a reorganization of the brain and changes in other organs. The evolutionary link between these changes and seasonality remains unclear, although the intensity of change varies between locations as the phenomenon is thought to lead to energy savings during winter. Here we explored geographic variation of...
