Convergent Evolution of Sociality Causes Reduction of Mutation Rates in Spiders Open
Germline mutations play a crucial role in determining the rate of molecular evolution. In the spider genus Stegodyphus , sociality has independently evolved three times within the past million years, each transition accompanied by major li…

Gene Flow Disruption and Population Declines in a Soil Arthropod in Fragmented Habitats Open
The intensification of land use over past millennia has accelerated habitat loss and fragmentation. This is hypothesized to lead to reductions in population sizes and restrictions in gene flow, processes that amplify genetic drift with pro…

The role of insularity: Plants have few ornithophilous traits but are visited by morphologically more distinct hummingbirds in the Caribbean islands Open
Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait ev…

Perspectives on mating–system evolution: comparing concepts in plants and animals Open
The study of mating systems, defined as the distribution of who mates with whom and how often in a sexually reproducing population, forms a core pillar of evolution research due to their effects on many evolutionary phenomena. Historically…

The genomic consequences and persistence of sociality in spiders Open
In cooperatively breeding social animals, a few individuals account for all reproduction. In some taxa, sociality is accompanied by a transition from outcrossing to inbreeding. In concert, these traits reduce effective population size, pot…

A modified iChip for <i>in situ</i> cultivation of bacteria in arid environments Open
Antimicrobial resistance is an ever-increasing problem for human health, and with only a few novel antimicrobials discovered in recent decades, an extraordinary effort is needed to circumvent this crisis. A promising source of new microbia…

Exploring changes in social spider DNA methylation profiles in all cytosine contexts following infection Open
Living at high density and with low genetic diversity are factors that should both increase the susceptibility of organisms to disease. Therefore, group living organisms, especially those that are inbred, should be especially vulnerable to…

The relationship between neutral genetic diversity and performance in wild arthropod populations Open
Larger effective populations (Ne) are characterized by higher genetic diversity, which is expected to predict population performance (average individual performance that influences fitness). Empirical studies of the relationship between ne…

Molecular Mechanisms of Temperature Tolerance Plasticity in an Arthropod Open
How species thrive in a wide range of environments is a major focus of evolutionary biology. For many species, limited genetic diversity or gene flow among habitats means that phenotypic plasticity must play an important role in their capa…

Seminatural areas act as reservoirs of genetic diversity for crop pollinators and natural enemies across Europe Open
Despite increasing recognition of the importance of the multiple dimensions of biodiversity, including functional or genetic diversity as well as species diversity, most conservation studies on ecosystem service‐providing insects focus on …

Facultative iteroparity in a semelparous social spider, Stegodyphus dumicola (Araneae: Eresidae) Open
Organisms can optimize their reproductive success by differential resource allocation. When adult survival is low, investment of all resources into a single reproductive event can be beneficial, favouring a semelparous strategy. In the spi…

Urbanization impacts short‐ but not long‐distance natal dispersal in a common orb web spider Open
Urban environments represent a theatre for life history evolution. Species able to survive in urban areas can adapt to the local and often divergent environmental conditions compared to rural or (semi‐)natural environments. Dispersal deter…

Does ecological drift explain variation in microbiome composition among groups in a social host species? Open
Within a given species, considerable inter-individual, spatial, and temporal variation in the composition of the host microbiome exists. In group-living animals, social interactions homogenize microbiome composition among group members, ne…

Social transmission of bacterial symbionts homogenizes the microbiome within and across generations of group-living spiders Open
Disentangling modes and fidelity of symbiont transmission are key for understanding host–symbiont associations in wild populations. In group-living animals, social transmission may evolve to ensure high-fidelity transmission of symbionts, …
