The surge in internet accessibility has transformed wildlife trade by facilitating the acquisition of wildlife through online platforms. This scenario presents unique ethical challenges for researchers, as traditional ethical frameworks for in‐person research cannot be readily applied to the online realm. Currently, there is a lack of clearly defin...

We present a genome assembly from an individual female Odiellus spinosus (harvestman spider; Arthropoda; Arachnida; Opiliones; Phalangiidae). The genome sequence spans 443.70 megabases. Most of the assembly is scaffolded into 16 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.07 kilobases in length.

We present a genome assembly from an individual female Amaurobius ferox (the Black Lace-weaver; Arthropoda; Arachnida; Araneae; Amaurobiidae). The genome sequence is 3,564.8 megabases in span. Most of the assembly is scaffolded into 23 chromosomal pseudomolecules, including the X1, X2 and X3 sex chromosomes. The mitochondrial genome has also been a...

With the increasing recognition of the significance of arachnid conservation, it is crucial to allocate greater efforts towards implementing targeted monitoring programmes. Despite recent studies, our understanding of arachnid populations in Portugal remains limited. This study serves as the initial inventory of arachnids (Araneae and Opiliones) wi...

We present a genome assembly from an individual male Metellina segmentata (the Autumn spider; Arthropoda; Arachnida; Aranae; Tetragnathidae). The genome sequence is 1,665.1 megabases in span. Most of the assembly is scaffolded into 13 chromosomal pseudomolecules, including the X1 and X2 sex chromosomes. The mitochondrial genome has also been assemb...

We present a genome assembly from an individual male Meta bourneti (the cave orb-weaver; Arthropoda; Arachnida; Araneae; Tetragnathidae). The genome sequence is 1,383 megabases in span. Most of the assembly is scaffolded into 13 chromosomal pseudomolecules, including half coverage of two X sex chromosomes. The mitochondrial genome has also been ass...

Global biodiversity decline is continuing largely unabated. The International Union for Conservation of Nature (IUCN) Red List of Threatened Species (hereafter, Red List) provides us with the gold standard for assessments, but taxonomic coverage, especially for invertebrates and fungi, remains very low. Many players contribute to the Red List knowl...

Despite their ecological importance and diversity, spiders (Arachnida: Araneae) are underrepresented in conservation policies in comparison to other groups. We review all extant conservation tools focusing on spiders in Europe, highlighting general patterns, limitations, gaps, and future directions. We assembled a comprehensive online database repo...

Population reductions are often used to assess extinction risk of species in the IUCN Red List. Guidelines for Red List assessments describe specific methods for calculating the amount of reduction for species with strongly fluctuating populations. Recently, an alternative approach that involves expert opinion has been suggested for calculating pop...

We describe and illustrate a new species of velvet spider from Iran, L. venatica sp. n., the first species of this genus outside of the Mediterranean region. We also resurrect Eresus jerbae from synonym, as a distinct and valid Loureedia species, L.jerbae comb.n, and record this genus to Jordan for the first time. We map the distribution of all ava...

Given the current biodiversity crisis, pragmatic approaches to detect global conservation trends across a broad range of taxa are critical. A sampled approach to the Red List Index (RLI) was proposed, as many groups are highly speciose. However, a decade after its conception, the recommended 900 species sample has only been implemented in six group...

CITES is an international agreement between governments to ensure that international trade in specimens of wild animals and plants does not threaten their survival. Regarding spiders, all species listed in CITES are tarantulas. They are included in Appendix II, meaning that they are species that are not necessarily now threatened with extinction bu...

Background: The Iberian Peninsula is a diverse region that contains several different bioclimatic areas within one confined space, leading to high biodiversity. Portugal distinguishes itself in this regard by having a high count of spider species (829) and a remarkable number of endemic spider species (42) for its size (approximately 88,890 km2)....

Background Data on 200 species of spiders were collected to assess the global threat status of the group worldwide. To supplement existing digital occurrence records from GBIF, a dataset of new occurrence records was compiled for all species using published literature or online sources, from which geographic coordinates were extracted or interprete...

The IUCN Red List of Threatened Species is the most widely used information source on the extinction risk of species. One of the uses of the Red List is to evaluate and monitor the state of biodiversity and a possible approach for this purpose is the Red List Index (RLI). For many taxa, mainly hyperdiverse groups, it is not possible within availabl...

We present the first recorded description of females of the species Dinorhax rostrumpsittaci (Simon, 1877) from solifugae specimens obtained from southern Vietnam. As a result of DNA barcoding using males identified as D. rostrumpsittaci and unidentified females, these female specimens made a highly supported cluster with male D. rostrumpsittaci. H...
