Weaving together the past, present and future of Greek arachnofauna: Biodiversity, knowledge gaps and conservation

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 158-171, January 2026.
Greece hosts 1310 species of spiders, 226 of which are endemic. Out of the 202 assessed species in IUCN standards, 64.5% are assessed as threatened. Integrating 187 articles and other forms of literature, we present 18,000 unique occurrences across continental and island Greece. Spider conservation in Greece should focus on obtaining distributional and

EineTapinauchenius-Art aus Ekuador (Araneida, Theraphosidae) [Tapinauchenius species from Ecuador (Araneida, Theraphosidae)]

open access: yesDeutsche Entomologische Zeitschrift (neue Folge), 1994
The new Tapinauchenius species can be distinguished from T. gigas di Caporiacco, 1954 by its shorter legs, other dentition of chelicera and the front row of eyes less weakly procurved. The spermatheca differs from that of T. plumipes (C. L. Koch, 1842) by thicker receptacula seminis which end with 5 or 6 small ovoides instead of one knob as in other ...

The value of public databases for our knowledge of national spider biodiversity compared to a long‐term scientific monitoring project

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 228-239, January 2026.
Records in citizen science platforms in Sweden are biased towards visible, diurnal, urban species but provide a cost‐effective way to gather large datasets and engage the public. National scientific surveys like the Swedish Malaise Trap Project remain essential to detect rare and cryptic species without activity bias, though some spider families are ...

Winter Temperature Affects Fatty Acid Composition and Gene Expression, but Not Fat Content and Survival in a Northern Population of a Range‐Expanding Spider

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study provides insight into the performance of a range‐expanding species and the physiological and molecular mechanisms underlying thermal tolerance at its expanding edge. ABSTRACT Species expand their geographic distribution when environmental conditions are favorable or when mutations arise that allow them to live in previously unfavorable ...

Testing for Differences in Consumer‐Based Nutrient Cycling Between Male and Female Wolf Spiders (Hogna carolinensis)

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We tested whether male and female wolf spiders (Hogna carolinensis) differ in how they regulate and excrete micronutrients. Our ecological experiment revealed significant differences in whole‐body and excreta elemental composition between sexes, providing new insight into how predator physiology shapes predator‐mediated nutrient cycles.
