A bioturbation classification of European marine infaunal invertebrates [PDF]

open access: yes, 2013
Bioturbation, the biogenic modification of sediments through particle reworking and burrow ventilation, is a key mediator of many important geochemical processes in marine systems.

Identification of orb-web spider species and their food source through environmental DNA analysis

open access: yesJournal of Ecology and Environment
Spiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the ...

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

open access: yesInsect Conservation and Diversity, EarlyView.
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

Description of Limb Anomalies Resulting from Molt Irregularities in Ammothea hilgendorfi (Pycnogonida: Ammotheidae)

open access: yesArthropoda
Limb anomalies are widespread and diversified in arthropods. From trilobites to insects, they range from the loss to the addition or fusion of legs and may appear congenitally or be induced experimentally (e.g., amputation or injury).

Toward a global repository of insect traits (GRIT)

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity loss is accelerating, yet insect conservation is hindered by the absence of a centralised, comprehensive trait database. We propose the GRIT, a FAIR, open‐access platform uniting datasets and collaborators worldwide. GRIT will harness advanced computational tools for trait acquisition and imputation, enabling large‐scale ecological ...

Evolutionary Conservation and Diversification of Five Pax6 Homologs in the Horseshoe Crab Species Cluster

open access: yesArthropoda
Horseshoe crabs represent the most ancestral chelicerate lineage characterized by marine ecology and the possession of lateral compound eyes. While considered living fossils, recent studies reported an unusual number of Pax6 genes in the Atlantic ...

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

open access: yesInsect Molecular Biology, EarlyView.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

A new marrellomorph euarthropod from the Early Ordovician of Argentina [PDF]

open access: yes, 2016
Marrellomorphs (class Marrellomorpha) are a group of Paleozoic arthropods with a very poor fossil record. Here we describe a new marrellomorph arthropod Mimetaster florestaensis sp. nov. from the Tremadocian (earliest Ordovician) of Argentina.

Trilobite Eyes and Their Evolution

open access: yesArthropoda
Trilobites, as typical euarthropods, possess compound eyes. In 1901, Lindström was the first to describe them in detail; on the one hand, we reconsider his descriptions of the different modes of trilobite eyes; on the other hand, we expand this by ...
