Loss, persistence and reversal of phenotypic traits

Biological 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 ...

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 ...

Characterization of ant-derived venom peptides

, 2018
Animal venoms have evolved throughout evolution to cover many different purposes such as defence, predation and communication. A major class of compounds in animal venoms are peptides, however, in ant venoms the study of these peptide toxins have until ...

Stability of Myrmecia pilosula (Jack Jumper) Ant venom for use in immunotherapy

, 2011
Allergy to Myrmecia pilosula (Jack Jumper Ant) venom is common in Australia, affecting ∼2.7% of some communities. Venom immunotherapy is a highly effective treatment, but for the venom to be widely distributed for clinical use, the stability and shelf ...

Proteomic View of the Venom from the Fire Ant Solenopsis invicta Buren

, 2016
Fire ants are well-known by their aggressive stinging behavior, causing many stinging incidents of medical importance. The limited availability of fire ant venom for scientific and clinical uses has restricted, up to now, the knowledge about the ...

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 ...

Proteomic analysis of the venom of the predatory ant Pachycondyla striata (Hymenoptera: Formicidae) [PDF]

, 2017
The ants use their venom for predation, defense, and communication. The venom of these insects is rich in peptides and proteins, and compared with other animal venoms, ant venoms remain poorly explored.

Characterization of the allergen Sol gem 2 from the fire ant venom, Solenopsis geminata

Journal of Venomous Animals and Toxins including Tropical Diseases, 2012
Sol i 2 is a potent allergen in Solenopsis invicta venom, and most humans exhibit reactivity to it. The Sol gem 2 allergen found in the venom of the Thai tropical fire ant Solenopsis geminata was analysed in the present study.
