Regeneration in Arachnida [PDF]

Nature, 1936
DURING last year I noticed that Harvestmen (Opiliones) do not regenerate lost legs when they moult, and this summer I have determined that they do not regenerate pedipalpi either. It seemed possible that this surprising deviation from a general character of the Arachnida might be related to the contrast between the length of the limbs and the shortness

Effectiveness of conservation lands in Mexico for safeguarding terrestrial endemic species from the human‐induced extinction crisis

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Across 1639 endemic Mexican species, we show that most species' ranges coincide with moderate to high human pressure, while existing conservation lands cover only a small fraction of their distributions. This spatial mismatch indicates that current conservation–land networks are insufficient to prevent future biodiversity loss. Substantial expansion of

Beyond species diversity: Functional responses of cave arthropods to microclimatic stability and structural complexity

Ecological Entomology, Volume 51, Issue 4, Page 715-728, August 2026.
Species richness declined along cave microclimatic gradient, while diversity increased with habitat heterogeneity, highlighting distinct roles of abiotic conditions and structural complexity in shaping arthropod communities. Functional traits shifted along the microclimatic gradient, with larger‐bodied and more eye‐regressed arthropods dominating under

Plant Phylogenetic History, Not Diversity, Drives Insect Biodiversity Across South Africa's Biomes

Global Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Insects provide essential ecosystem services, but there is a concern that insect abundance is in rapid decline. Identifying trends in insect biodiversity is challenging because we lack baseline data for most biogeographic regions, and most insect species remain undescribed.

Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120

South African National Survey of Arachnida (SANSA): Solifugae (sun-spiders) of the national parks and reserves of South Africa (Arachnida, Solifugae)

Koedoe: African Protected Area Conservation and Science, 2006
As part of the South African National Survey of Arachnida (SANSA) inventories are underway to determine the diversity of the South African Arachnida fauna (Dippenaar- Schoeman & Craemer 2000).

Molecular Phylogenetic Reassessment of the Superfamily Eriophyoidea (Arachnida: Acari) Based on COI and 18S rRNA

Entomological Research, Volume 56, Issue 7, July 2026.
ABSTRACT Gall mites (superfamily Eriophyoidea) are highly specialized phytophagous arthropods with extreme host plant specificity and marked morphological diversity. Despite extensive taxonomic and molecular research, phylogenetic relationships within the superfamily remain unresolved, largely due to persistent polyphyly among several families.
