Data from: A nation-wide survey of neonicotinoid insecticides in agricultural land with implications for agri-environment schemes

Ségolène Humann-Guilleminot, Łukasz Binkowski, Lukas Jenni, Gabriele Hilke, Gaétan Glauser & Fabrice Helfenstein
1. Neonicotinoids are the most widely used class of insecticides globally. However, the link between farming practices and the extent of contamination of soils and crops by neonicotinoid insecticides, as well as and the extent of such contamination in organic fields and ecological focus areas (EFAs) are currently unclear. 2. We measured the concentrations of five neonicotinoid insecticides (imidacloprid, clothianidin, thiamethoxam, thiacloprid, acetamiprid) in 702 soil and plant samples in 169 cultivated fields and EFAs...

Data from: A full annual perspective on sex-biased migration timing in long-distance migratory birds

Martins Briedis, Silke Bauer, Peter Adamik, José A. Alves, Joana S. Costa, Tamara Emmenegger, Lars Gustafsson, Jaroslav Koleček, Felix Liechti, Christoph M. Meier, Petr Prochazka & Steffen Hahn
In many taxa, the most common form of sex-biased migration timing is protandry – the earlier arrival of males at breeding areas. Here we test this concept across the annual cycle of long-distance migratory birds. Using more than 350 migration tracks of small-bodied trans-Saharan migrants, we quantify differences in male and female migration schedules and test for proximate determinants of sex-specific timing. In spring, males on average departed from the African non-breeding sites about 3...

Data from: Effects of forest wildfire on inner-Alpine bird community dynamics

Livio Rey, Marc Kéry, Antoine Sierro, Bertrand Posse, Raphaël Arlettaz & Alain Jacot
As major disturbance agents, natural catastrophes impact habitats, thereby maintaining the dynamics of ecological communities. Such discrete events are expected to positively affect biodiversity because they generate high habitat heterogeneity and thus numerous ecological niche opportunities. Species typical of open and semi-open habitats, which are often of high conservation concern in modern anthropized landscapes, may benefit most from recurrent natural catastrophes that regularly reset ecosystems. We investigated bird community changes and species-specific responses to wildfire...

Data from: The landscape genetic signature of pollination by trapliners: evidence from the tropical herb, Heliconia tortuosa

Felipe Torres-Vanegas, Adam S. Hadley, Urs G. Kormann, F. Andrew Jones, Matthew G. Betts & Helene H. Wagner
Animal-mediated pollination is essential for the maintenance of plant reproduction, especially in tropical ecosystems, where pollination networks have been thought to have highly generalized structures. However, accumulating evidence suggests that not all floral visitors provide equally effective pollination services, potentially reducing the number of realized pollinators and increasing the cryptic specialization of pollination networks. Thus, there is a need to understand how different functional groups of pollinators influence pollination success. Here we examined whether patterns...

Data from: Baseline and stress-induced corticosterone levels are heritable and genetically correlated in a barn owl population

Paul Béziers, Luis M. San José Garcia, Bettina Almasi, Lukas Jenni & Alexandre Roulin
The hypothalamic-pituitary-adrenal (HPA) axis is responsible for the regulation of corticosterone, a hormone that is essential in the mediation of energy allocation and physiological stress. As a continuous source of challenge and stress for organisms, the environment has promoted the evolution of physiological adaptations and led to a great variation in corticosterone profiles within or among individuals, populations and species. In order to evolve via natural selection, corticosterone levels do not only depend on the...

Data from: Testing species assemblage predictions from stacked and joint species distribution models

Damaris Zurell, Niklaus E. Zimmermann, Helge Gross, Andri Baltensweiler, Thomas Sattler & Rafael O. Wüest
Aim: Predicting the spatial distribution of species assemblages remains an important challenge in biogeography. Recently, it has been proposed to extend correlative species distribution models (SDMs) by taking into account (a) covariance between species occurrences in so-called joint species distribution models (JSDMs) and (b) ecological assembly rules within the SESAM (spatially explicit species assemblage modelling) framework. Yet, little guidance exists on how these approaches could be combined. We, thus, aim to compare the accuracy of...

Data from: Carcass predictability but not domestic pet introduction affects functional response of scavenger assemblage in urbanised habitats

Patrick Scherler, Martin U. Grüebler & Nora Welti
Urbanisation alters species richness and composition, but studies of urbanisation effects on ecological functions have often quantified variation in functional traits and changes in functional diversity rather than measuring directly how ecological functions vary between rural and urban assemblages. Consuming dead animal matter and recycling its nutrients stabilizes and structures food webs and therefore represents a key component of ecosystem functioning. Introduction of free-ranging domestic pet animals adds additional scavenger species to urban habitats, and...

Field evaluation of abundance estimates under binomial and multinomial N‐mixture models

Yves Bötsch, Lukas Jenni & Marc Kéry
Assessing and modelling abundance from animal count data is a very common task in ecology and management. Detection is arguably never perfect, but modern hierarchical models can incorporate detection probability and yield abundance estimates that are corrected for imperfect detection. Two variants of these models rely on counts of unmarked individuals, or territories, (binomial N‐mixture models, or binmix) and on detection histories based on territory mapping data (multinomial N‐mixture models or multimix). However, calibration studies...

Data from: Broad-scale patterns of the Afro-Palearctic landbird migration

Martins Briedis, Silke Bauer, Peter Adamík, José Alves, Joana Costa, Tamara Emmenegger, Lars Gustafsson, Jaroslav Koleček, Miloš Krist, Felix Liechti, Simeon Lisovski, Christoph Meier, Petr Procházka & Steffen Hahn
Aim: Animal migration strategies balance trade-offs between mortality and reproduction in seasonal environments. Knowledge of broad-scale biogeographical patterns of animal migration is important for understanding ecological drivers of migratory behaviours. Here we present a flyway-scale assessment of the spatial structure and seasonal dynamics of the Afro-Palearctic bird migration system and explore how phenology of the environment guides long-distance migration. Location: Europe and Africa. Time period: 2009–2017. Major taxa studied: Birds. Methods: We compiled an individual-based...
