Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Araneae Sloveniae: a national spider species checklist

ZooKeys, 2015
The research of the spider fauna of Slovenia dates back to the very beginning of binomial nomenclature, and has gone through more and less prolific phases with authors concentrating on taxonomy, faunistics, ecology and zoogeographic reviews. Although the body of published works is remarkable for a small nation, the faunistic data has remained too ...

The first record of Oecobius nadiae (Spassky, 1936) (Aranei: Oecobiidae) in Russia [PDF]

Кавказский энтомологический бюллетень
Oecobius nadiae (Spassky, 1936) is registered on the territory of Russia for the first time. A single male was found indoors in Makhachkala (Dagestan). This male is slightly larger in size than type specimens.

Social media highlights the overlooked impact of cats on arthropods

Insect Conservation and Diversity, EarlyView.
The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.

Coexistence of spiders in floodplain forests as an indicator of ecological stability and landscape sustainability in the inland Danube Delta

Central European Forestry Journal
The coexistence of spiders in the Central European floodplains of the Danube River was assessed at 18 study sites (more than 43,000 individuals identified). Environmental conditions, i.e. groundwater level, flood regime, vegetation and tree shading, were

Resilience of riparian spiders to floods: evidence from a mesocosm study

Insect Conservation and Diversity, EarlyView.
Mesocosm experiment to assess the impact of flood duration on flood‐naïve riparian spider communities. In May, spider richness decreased with flood duration, while in June, flood duration increased abundance, richness and promoted wetland specialists. Flood‐naïve riparian spiders unexpectedly appear highly resilient to flooding.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

Insect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling
