Mouthpart morphology and feeding structures in the palaeocharinid trigonotarbids of the Rhynie chert: insights from comparisons to modern arachnids

open access: yesPalaeontology, Volume 67, Issue 4, July/August 2024.
Abstract Trigonotarbida, an extinct order of spider‐like arachnids, were significant predators between the late Silurian and early Permian. Characterized by their segmented opisthosoma, clasp‐knife chelicera, and paired book lungs, they played a pivotal role in the formation of Early Devonian terrestrial ecosystems.

Invertebrate diversity in groundwater‐filled lava caves is influenced by both neutral‐ and niche‐based processes

open access: yesEcology and Evolution, Volume 14, Issue 6, June 2024.
Here, we examine how ecological factors shape invertebrate diversity in ponds found in lava caves in Iceland. We specially focus on the importance of neutral and niche‐based processes. Abstract Understanding which factors shape and maintain biodiversity is essential to understand how ecosystems respond to crises.

Pest categorisation of Cenopalpus irani

open access: yesEFSA Journal, Volume 22, Issue 6, June 2024.
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Cenopalpus irani (Trombidiformes: Tenuipalpidae), known as the Iranian false spider mite, following the commodity risk assessment of Malus domestica plants from Türkiye, in which C.

The “elongate chelicera problem”: A virtual approach in an extinct pterygotid sea scorpion from a 3D kinematic point of view

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
How pterygotid sea scorpions used their tripartite elongate cheliceres to get prey items close to the mouth region remains a conundrum. We applied four different 3D kinematic settings with regard to insertion and orientation of the cheliceres to examine the most likely way this was realized.

Host space, not energy or symbiont size, constrains feather mite abundance across passerine bird species

open access: yesJournal of Animal Ecology, Volume 93, Issue 4, Page 393-405, April 2024.
Why some host species hold larger symbiont abundances than others is an open question in ecology. Comparison of the empirical scaling of feather mite abundance with predictions from the metabolic theory of ecology showed that space (number of feather barbs of bird species), and not energy, was the main constraint to feather mite infracommunities ...
