Data from: Food limitation constrains host immune responses to nematode infections

Kristian M. Forbes, Tapio Mappes, Tarja Sironen, Tomas Strandin, Peter Stuart, Seppo Meri, Olli Vapalahti, Heikki Henttonen & Otso Huitu
Trade-offs in the allocation of finite-energy resources among immunological defences and other physiological processes are believed to influence infection risk and disease severity in food-limited wildlife populations. However, this prediction has received little experimental investigation. Here we test the hypothesis that food limitation impairs the ability of wild field voles (Microtus agrestis) to mount an immune response against parasite infections. We conducted a replicated experiment on vole populations maintained in large outdoor enclosures during boreal...

Data from: The golden mimicry complex uses a wide spectrum of defence to deter a community of predators

Stano Pekár, Lenka Petráková, Matthew W. Bulbert, Martin J. Whiting & Marie E. Herberstein
Mimicry complexes typically consist of multiple species that deter predators using similar anti-predatory signals. Mimics in these complexes are assumed to vary in their level of defence from highly defended through to moderately defended, or not defended at all. Here, we report a new multi-order mimicry complex that includes at least 140 different putative mimics from four arthropod orders including ants, wasps, bugs, tree hoppers and spiders. All members of this mimicry complex are characterised...

Data from: A cost-efficient and simple protocol to enrich prey DNA from extractions of predatory arthropods for large-scale gut content analysis by Illumina sequencing

Henrik Krehenwinkel, Susan Kennedy, Stano Pekár & Rosemary G. Gillespie
Molecular analysis of predator gut content is a popular tool to uncover food web structure and has greatly profited from the emergence of next-generation sequencing technology. However, the molecular recovery of prey spectra comes with many challenges, particularly the overabundance of predator DNA in extractions. When predator and prey are distantly related, predator-specific blocking primers can be used to preferentially amplify prey DNA. But this is difficult in the case of arthropods, where prey and...

Data from: Weak link between dispersal and parasite community differentiation or immunogenetic divergence in two sympatric cichlid fishes

Pascal I. Hablützel, Arnout F. Grégoir, Maarten P. M. Vanhove, Filip A. M. Volckaert & Joost A. M. Raeymaekers
Geographical isolation, habitat variation and trophic specialization have contributed to a large extent to the astonishing diversity of cichlid fishes in the Great East African lakes. Because parasite communities often vary across space and environments, parasites can accompany and potentially enhance cichlid species diversification. However, host dispersal may reduce opportunities for parasite-driven evolution by homogenizing parasite communities and allele frequencies of immunity genes. To test for the relationships between parasite community variation, host dispersal and...

Data from: Fine-scale vertical stratification and guild composition of saproxylic beetles in lowland and montane forests: similar patterns despite low faunal overlap

Matthias Weiss, Jiří Procházka, Jiří Schlaghamerský & Lukas Cizek
The finer scale patterns of arthropod vertical stratification in forests are rarely studied and poorly understood. Further, there are no studies investigating whether and how altitude affects arthropod vertical stratification in temperate forests. We therefore investigated the fine-scale vertical stratification of diversity and guild structure of saproxylic beetles in temperate lowland and montane forests and compared the resulting patterns between the two habitats. The beetles were sampled with flight intercept traps arranged into vertical transects...

Data from: Metazoan parasites of African annual killifish (Nothobranchiidae): abundance, diversity, and their environmental correlates

Veronika Nezhybová, Martin Reichard, Radim Blažek & Markéta Ondračková.
Estimates of biodiversity and its global patterns are affected by parasite richness and specificity. Despite this, parasite communities are largely neglected in biodiversity estimates, especially in the tropics. We studied the parasites of annual killifish of the genus Nothobranchius that inhabit annually desiccating pools across the African savannah and survive the dry period as developmentally arrested embryos. Their discontinuous, non-overlapping generations make them a unique organism in which to study natural parasite fauna. We investigated...

Data from: No evidence for larger leaf trait plasticity in ecological generalists compared to specialists

Petr Dostál, Markus Fischer, Milan Chytrý & Daniel Prati
Aim: Phenotypic plasticity is hypothesized to contribute to a species’ capacity to occupy broader ranges of conditions and to optimally exploit resource-rich environments. Although this is supported by case studies of individual species, we do not know whether larger plasticity in functional traits is generally associated with ecological characteristics of species such as their niche breadth or niche position. Here, we test whether there is such a relationship for plasticity in leaf functional traits. Location:...
