Pesticides and habitat loss additively reduce wild bees in crop fields Open
Pesticide use and habitat loss are major anthropogenic drivers of bee decline, raising global concerns about impaired crop pollination. However, the relative importance of these stressors and their combined impact on bee assemblages compri…

The hydrological archetypes of wetlands Open
Wetlands are valuable and diverse environments that contribute to a vast range of ecosystem services, such as flood control, drought resilience, and carbon sequestration. The provision of these ecosystem services depends on their hydrologi…

Scale-dependent responses in spider and beetle communities to flooding: the role of dry refuges in wetlands Open
Context Flood disturbances act as strong filters on arthropod communities by excluding species that are not adapted to the high water-tables. Sensitive species can survive in these areas by either migrating to more terrestrial habitats or …

Detritivore-driven seed viability gains offset seed loss from florivores in a semiarid herb Open
Background and aims Florivory poses a threat to the sexual reproductive success of plants, having both quantitative and qualitative effects by reducing seed yield and seed quality. Plants can resist herbivory, tolerate damage, or employ a …

Bottom–up and top–down diversification: asymmetric processes over space and time Open
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host‐associated differentiation drives diversifi…

Lineage-specific targets of positive selection in three leaf beetles correspond with defence capacity against their shared parasitoid wasp Open
Parasitoid wasps are major causes of mortality of many species, making host immune defences a common target of adaptive evolution, though such targets outside model species are poorly understood. In this study, we used two tests of positiv…

Deterring egg predators with faecal strings is more efficient when eggs are aggregated Open
Predation can be a great source of mortality for insect eggs. Thus, female insects use multiple strategies to reduce it. Two common strategies are to aggregate eggs, which may function to satiate egg predators, and various deterrence strat…

Microbial transfer through fecal strings on eggs affects leaf beetle microbiome dynamics Open
Gut microbiomes of holometabolous insects can be strongly affected by metamorphosis. Previous studies suggest that microbiome colonization and community development often rely on specialized transmission routes between host life stages. Ho…

Variation in Odour Profiles of Cauliflower, Curly Kale and Broccoli (Brassica oleracea L.) Cultivars Is Affected More by Genotype Rather than Herbivore Feeding Open
Volatile plant compounds are essential for host plant selection by herbivores and particularly important for the behaviour of parasitoids seeking larvae in which to lay eggs. Headspace extracts were collected from intact plants of four Bra…

Shift in diet composition of a riparian predator along a stream pollution gradient Open
Terrestrial insectivores in riparian areas, such as spiders, can depend on emergent aquatic insects as high-quality prey. However, chemical pollution entering streams from agricultural and urban sources can alter the dynamics and compositi…
View article: Parasitoid speciation and diversification
Parasitoid speciation and diversification Open
Parasitoid wasps may well be the most species-rich animal group on Earth, and host-parasitoid interactions may thereby be one of the most common types of species interactions. Understanding the major mechanisms underlying diversification i…

Hydrological dynamics, wetland morphology and vegetation structure determine riparian arthropod communities in constructed wetlands Open
Wetland hydrological dynamics often dictate the composition of biological communities found in or near wetlands, either directly or through changes in vegetation composition. However, much remains unknown, particularly regarding how ripari…

Arthropod diversity in constructed wetlands is affected strongly by shoreline properties but only weakly by grazing Open
Aim Aquatic‐terrestrial transition zones contain features essential for many species that often benefit wetland biodiversity. Shallow flood‐zone areas and reed beds are indicative of natural wetland habitats; however, how such features aff…

Dynamics of Gut Bacteria Across Different Zooplankton Genera in the Baltic Sea Open
In aquatic ecosystems, zooplankton-associated bacteria potentially have a great impact on the structure of ecosystems and trophic networks by providing various metabolic pathways and altering the ecological niche of host species. To unders…

Sources of prey availability data alter interpretation of outputs from prey choice null networks Open
Null models provide a valuable baseline against which fundamental ecological hypotheses can be tested and foraging choices that cannot be explained by neutral processes or sampling biases can be highlighted. In this way, null models can ad…

Wetland productivity determines trade‐off between biodiversity support and greenhouse gas production Open
Establishing wetlands for nutrient capture and biodiversity support may introduce trade‐offs between environmentally beneficial functions and detrimental greenhouse gas emissions. Investigating the interaction of nutrient capture, primary …

Lineage-specific targets of positive selection in three leaf beetles with different defence capacity against a parasitoid wasp Open
Parasitoid wasps are major causes of mortality of many species, resulting in host immune defences commonly being the target of adaptive evolution, though such targets outside model species are poorly understood. Here we compare the power o…

Different spatial structure of plant‐associated fungal communities above‐ and belowground Open
The distribution and community assembly of above‐ and belowground microbial communities associated with individual plants remain poorly understood, despite its consequences for plant–microbe interactions and plant health. Depending on how …

Density-Dependent Effects of Simultaneous Root and Floral Herbivory on Plant Fitness and Defense Open
Plants are attacked by multiple herbivores, and depend on a precise regulation of responses to cope with a wide range of antagonists. Simultaneous herbivory can occur in different plant compartments, which may pose a serious threat to plan…

Species composition of shoreline wolf spider communities vary with salinity, but their diets vary with wrack inflow Open
Wolf spiders are typically the most common group of arthropod predators on both lake and marine shorelines because of the high prey availability in these habitats. However, shores are also harsh environments due to flooding and, in proximi…
