The Nonpeptide Low Molecular Mass Toxins from Spider Venoms

open access: yes, 2016
Spiders occupy most of the ecological niches of the planet, revealing a huge adaptive plasticity, reflected in the chemical diversity of their venom toxins.

Determining the pharmacological potential and biological role of linear pseudoscorpion toxins via functional profiling

open access: yesiScience
Summary: Arthropod venoms contain bioactive molecules attractive for biomedical applications. However, few of these have been isolated, and only a tiny number has been characterized.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

The invasive herb Lupinus polyphyllus attracts bumblebees but reduces total arthropod abundance [PDF]

open access: yes, 2022
Invasive plant species generally reduce the abundance and diversity of local plant species, which may translate into alterations at higher tropic levels, such as arthropods.

Gut Microbiome Diversity, Functional Potential, and Ecological Relevance of Hottentotta tamulus

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Long‐read 16S sequencing uncovers the gut microbiome of H. tamulus. A highly conserved and low‐diversity bacterial community dominates the gut fauna. Bacillus and Mycoplasma lineages emerge as predominant candidate endosymbionts. Exploratory profiles reveal potential sex‐specific trends in microbial abundance.

Senecioylcholine in Heterometrus spinifer scorpion venom activates vertebrate nicotinic acetylcholine receptors

open access: yesFrontiers in Arachnid Science
IntroductionScorpion venoms are natural sources of neurotoxins that primarily modulate the properties of neuronal ion channels, particularly voltage-gated sodium and potassium channels.

No gain from pain: Lack of nociceptor activation suggests no adaptation for defence in the evolution of European viper venoms

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3048-3062, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Snake venoms show variability in composition at all taxonomic levels, both within and between species, and the selective pressures underlying this variation have long been debated.

Darwin's Naturalization Conundrum in the Azores: Scale‐Dependent Patterns of Arthropod Invasion

open access: yesDiversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim To test the mechanisms governing the assembly of exotic arthropods within endemic‐rich island communities by evaluating Darwin's naturalization conundrum, which predicts that invasion success occurs through either functional dissimilarity from native species (Naturalization Hypothesis) or functional similarity with them (Pre‐adaptation ...

Potency Testing of Venoms and Antivenoms in Embryonated Eggs: An Ethical Alternative to Animal Testing

open access: yes, 2021
Venoms are complex mixtures of biologically active molecules that impact multiple physiological systems. Manufacture of antivenoms (AVs) therefore requires potency testing using in vivo models to ensure AV efficacy. As part of ongoing research to replace

Epidemiological aspects of centipede (Scolopendromorphae: Chilopoda) bites registered in Greater S. Paulo, SP, Brazil

open access: yesRevista de Saúde Pública, 1998
INTRODUCTION: The lack of basic knowledge on venomous arthropods and the benignity of the clinical manifestations contribute to the centipede bite victims' not being taken to a treatment reference center, leading to underestimation of the number of cases
