  Climatic and density-dependent drivers of population dynamics in a hazardous urban scorpion species over seven years Abstract This link goes to a Portuguese section Tityus serrulatus Lutz & Mello (Scorpiones: Buthidae) is the most medically important scorpion in Brazil, responsible for a growing number of accidents in urban areas. Despite its relevance, the population dynamics of this species in anthropogenic habitats remain poorly understood, particularly regarding the influence of abiotic factors on its abundance and reproduction. We analysed long-term data (2006–2013) from T. serrulatus collected in an urban cemetery in the municipality of Americana, São Paulo State, Brazil. Using spatiotemporal mixed models, we evaluated the effects of temperature and humidity at the graves on the abundance of brooded and non-brooded individuals, as well as on the ratio between the two reproductive groups. A total of 21,489 individuals were recorded, including 463 brooded individuals. W...

New data on spiders (Arachnida, Araneae) of Türkiye, with descriptions of four new species

Abstract

New taxonomic and faunistic data on Turkish spiders are presented. Four species are described as new to science: Cybaeus anatolicus sp. nov. (♀; Konya) [Cybaeidae], Dictyna caligaformis sp. nov. (♂♀; Bursa) [Dictynidae], Leptonetela ayvaensis sp. nov. (♂♀; Bursa), and L. oylatensis sp. nov. (♂; Bursa) [Leptonetidae]. Except for Cybaeus anatolicus sp. nov., the remaining new species were collected in caves. Additionally, Drassodes robatus Roewer, 1961 [Gnaphosidae] is recorded from Türkiye for the first time, and an unusual variation in the shape of the retrolateral tibial apophysis is documented in an unidentified congener. Additional illustrations are provided for Cataleptoneta aydintopcui Demircan, 2020 [Leptonetidae] and Pterotricha kochi (O. Pickard-Cambridge, 1872) [Gnaphosidae], for which new localities in Türkiye are reported, as well as for Troglohyphantes karolianus Topçu, Türkes & Seyyar, 2008 [Linyphiidae], included here based on topotypic material.
