Relational knowing as method and practice

People and Nature, Volume 8, Issue 10, Page 3585-3600, October 2026.
Abstract This paper seeks to contribute to (re)building the capacity for embodied, place‐based relational knowing, transforming how we know and thus what we know. What is known, or sought to be known, is relations. How we know these relations is by already being in it: breathing, sensing, moving, listening, responding, affecting and being affected ...

Intraspecific variations in the venom peptidome of the ant Odontomachus haematodus (formicidae: ponerinae) from French Guiana

, 2015
Ant venoms are complex cocktails of toxins employed to subdue prey and to protect the colony from predators and microbial pathogens. Although the extent of ant venom peptide diversity remains largely unexplored, previous studies have revealed the ...

Varespladib (LY315920) and Methyl Varespladib (LY333013) Abrogate or Delay Lethality Induced by Presynaptically Acting Neurotoxic Snake Venoms [PDF]

, 2020
The phospholipase A2 (PLA2) inhibitor Varespladib (LY315920) and its orally bioavailable prodrug, methyl-Varespladib (LY333013) inhibit PLA2 activity of a wide variety of snake venoms.

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

Functional 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.

Genome of the green-head ant, Rhytidoponera metallica, reveals mechanisms of toxin evolution in a genetically hyper-diverse eusocial species

Genome Biology
Background While ants are textbook examples of eusocial animals in which altruistic behavior is maintained through kin selection, several ants form genetically diverse colonies that challenge this concept.

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

Diversity 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 ...

The genome of the ant Tetramorium bicarinatum reveals a tandem organization of venom peptides genes allowing the prediction of their regulatory and evolutionary profiles

BMC Genomics
Background Venoms have evolved independently over a hundred times in the animal kingdom to deter predators and/or subdue prey. Venoms are cocktails of various secreted toxins, whose origin and diversification provide an appealing system for evolutionary ...

Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

Ecological Entomology, Volume 51, Issue 5, Page 926-943, October 2026.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Web page classification with an ant colony algorithm [PDF]

, 2004
This paper utilizes Ant-Miner - the first Ant Colony algorithm for discovering classification rules - in the field of web content mining, and shows that it is more effective than C5.0 in two sets of BBC and Yahoo web pages used in our experiments.

A New Kv1.3 Channel Blocker from the Venom of the Ant Tetramorium bicarinatum

Toxins
Ant venoms are rich sources of bioactive molecules, including peptide toxins with potent and selective activity on ion channels, which makes them valuable for pharmacological research and therapeutic development. Voltage-dependent potassium (Kv) channels,
