In many species, individuals can develop into strikingly different morphs, which are determined by a simple Mendelian locus. How selection shapes loci that control complex p henotypic differences remains poorly understood. In the spider gibbosus, males either develop into a ‘hunched’morph with conspicuous head structures or as a fast developing ‘flat’morph with a female- like appearance. We show that the hunched differs from the f lat-determinin g allele by a hunch-specific genomic fragment of approximately...

Maintaining the diversity of wild bees is a priority for preserving ecosystem function and promoting stability and productivity of agroecosystems. However, wild bee communities face many threats and beekeeping could be one of them, because honey bees may have a strong potential to outcompete wild pollinators when placed at high densities. Yet, we still know little about how beekeeping intensity affects wild bee diversity and their pollinator interactions. Here, we explore how honey bee density...

Many hypotheses have been proposed to explain the coexistence of ants sharing similar food resources, including ecological trade-offs, however, these hypotheses have mostly been tested in ground-dwelling ant communities. For instance, the discovery-dominance trade-off hypothesis states that species with overlapping food resources differ in their ability to find and dominate resources. However, ant species may use different strategies to share food resources, including discovery-defense, in which the first species to arrive at a food resource...

Aim The species of the genus Chionodraco (Notothenioidei) are the most abundant icefish on the continental shelf of the Weddell Sea. While previous studies indicated that only Chionodraco hamatus and Chionodraco myersi inhabit the Weddell Sea, the third Chionodraco species, Chionodraco rastrospinosus, was recently sampled in the area. Since C. rastrospinosus is supposed to be found only at the Antarctic Peninsula and Scotia Arc, this study aimed at confirming the species classification of C. rastrospinosus...

The dataset contains the individual fish and otolith measurements necessary to analyse the early-life history stages of juvenile common sole in the Southern North Sea. Samples were collected at three major nursery grounds, the Belgian coast, the Dutch coast and the UK coast between 2013 and 2016. The analysis of the otolith microstructures (daily growth rings) allows the back calculation of hatching and settlement periods as well as the investigation of growth conditions. The dataset...
