Spintharus flavidus in the Caribbean—a 30 million year biogeographical history and radiation of a ‘widespread species’ [PDF]

PeerJ, 2015
The Caribbean island biota is characterized by high levels of endemism, the result of an interplay between colonization opportunities on islands and effective oceanic barriers among them.

Temperate forest heterogeneity decreases local and landscape‐scale spider diversity through habitat filtering despite increasing species turnover

Journal of Animal Ecology, Volume 95, Issue 9, Page 1793-1806, September 2026.
In a large‐scale German forest experiment, habitat heterogeneity increased spider turnover but reduced local alpha diversity through habitat filtering. Together, these effects lowered landscape‐scale spider diversity. As such, the study shows whether environmental heterogeneity increases or decreases biodiversity depends on the balance between habitat ...

Non‐Invasive Body Mass Estimation in the Ladybird Spider, Eresus kollari, Using Multi‐View Morphometrics and Machine Learning

Entomological Research, Volume 56, Issue 9, September 2026.
ABSTRACT Body mass is widely used as an indicator of physiological condition and ecological fitness in spiders. However, directly measuring the mass of small, live individuals remains technically challenging. In this study, we evaluated a non‐invasive approach for predicting body mass in Eresus kollari using machine learning‐based (ML) models derived ...

Functional and Taxonomic Structuring of Ground‐Dwelling Spider Communities Under the Combined Effects of the Environment and Metal Contamination

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Through a field study along a metal contamination gradient, we propose a combined application of taxonomic and functional approaches to study the impacts of contamination on polyphagous predators, spiders. We have demonstrated a significant impact of metal contamination on spider communities, although it operates among a set of variables (e.g ...

Comparison of lowland tropical forest spider (Araneae) assemblages from Congo and Panama using a rapid assessment protocol [PDF]

African Invertebrates
A Rapid Assessment Protocol (RAP) for non-canopy spiders was used to collect replicate samples from four lowland rainforest sites for a proof-of-concept comparison of spider assemblages from the Democratic Republic of the Congo (hereafter, Congo) and ...

Effects of chronic exposure to cadmium and copper on the proteome profile of hemolymph in false widow spider Steatoda grossa (Theridiidae)

Ecotoxicology and Environmental Safety, 2023
The aim of this study was to evaluate the quantitative and qualitative changes in the proteome of the hemolymph of female Steatoda grossa spiders (Theridiidae) that were chronically exposed to cadmium and copper in food and were additionally ...

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

Journal of Applied Entomology, Volume 150, Issue 7, Page 955-967, August 2026.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

Hunting Guild Mediates the Effects of Fecundity and Mortality on Sexual Size Dimorphism in Spiders

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Female red‐legged golden orb‐weaver (Trichonephila inaurata madagascarensis) with a much smaller male visible near the tip of the female abdomen, southwest Madagascar. Orb‐web weavers are characterised by relatively sedentary females occupying aerial orb webs and highly mobile mate‐searching males.
