Migratory insects are capable of actively sustaining powered flight for several hours. This extraordinary phenomenon requires a highly efficient transport system to cope with the energetic demands placed on the flight muscles. Here, we provide evidence that the role of the hydrophobic ligand binding of odorant binding proteins (OBPs) extends beyond their typical function in the olfactory system to support insect flight activity via lipid-interactions. Transcriptomic and candidate gene analyses s...

Knowledge of zooplankton in situ diet is critical for accurate assessment of marine ecosystem function and structure, but due to methodological constraints, there is still a limited understanding of ecological networks in marine ecosystems. Here, we used DNA-metabarcoding to study trophic interactions, with the aim to unveil the natural diet of zooplankton species under temporal variation of food resources. Several target consumers, including copepods and cladocerans, were investigated by sequen...

Mycorrhizal fungi transfer nutrients to plants in exchange for photosynthates. Plants allocate up to 20% of their carbon to mycorrhizal structures, mycelium and fruit bodies of their fungal partners. Individuals of mycorrhizal fungi may encompass hundreds of square metres of soil and defragmented litter, linking multiple plant individuals of different species and size (Figure 1). Using a free-air 13 CO2 enrichment (web-FACE) technique in a mature forest, interspecific transfer accounted for 40% ...

The Southern Ocean is characterized by longitudinal water circulations crossed by strong latitudinal gradients. How this oceanographic background shapes planktonic populations is largely unknown, despite the significance of this region for global biogeochemical cycles. Here we show , based on genomic, morphometric, ecophysiological and mating compatibility data, an example of ecotypic differentiation and speciation within an endemic pelagic inhabitant, the diatom Fragilariopsis kerguelensis. We ...

The evolutionary consequences of individual genetic diversity are frequently studied by assessing heterozygosity-fitness correlations (HFCs). The prevalence of positive and negative HFCs and the predominance of general versus local effects in wild populations are far from understood, partly because comprehensive studies testing for both inbreeding and outbreeding depression are lacking. We studied a genetically diverse population of blue tits in southern Germany using a genome-wide set of 87 mic...

Harvest can affect vital rates such as reproduction and survival, but also genetic measures of individual and population health. Gray wolves (Canis lupus) live and breed in groups and effective population size is a small fraction of total abundance. As a result, genetic diversity of wolves may be particularly sensitive to harvest. We evaluated how harvest affected genetic diversity and relatedness in wolves. We hypothesized that harvest would 1) reduce relatedness of individuals within groups in...

It has been long assumed that abiotic factors (i.e., geography and climate) dominate the ecological and evolutionary processes underlying the distribution of species, lineages and genes at broad spatial scales and, as a result, the study of interspecific interactions has largely been overlooked in biogeography research and ignored entirely in phylogeographic inference. Here, we focus on plant-plant interactions and test whether their demographic consequences translate into broad-scale patterns o...

Knowledge of how animal species use food resources available in the environment increases our understanding of ecological processes. However, obtaining this information using traditional methods is a hard task for species feeding on a large variety of food items in highly diverse environments. We amplified the DNA of plants for 306 scat and 40 soil samples, and applied an eDNA metabarcoding approach to investigate food preferences, degree of diet specialization and diet overlap of seven herbivor...

Genes of the major histocompatibility complex (MHC) play a pivotal role in parasite resistance, and their allelic diversity has been associated with fitness variations in several taxa. However, studies report inconsistencies in the direction of this association, with either positive, quadratic or no association being described. These discrepancies may arise because the fitness costs and benefits of MHC-diversity differ among individuals depending on their exposure and immune responses to parasit...
