Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Size, Spines, and Nests: What Drives Variation in Death‐Feigning Behavior in Fungus‐Farming Ants?
Integrative Zoology, EarlyView.We investigated death‐feigning (DF; thanatosis) in fungus‐farming ants, testing how stimulus intensity, morphology, and nest traits shape its occurrence and duration using generalized linear mixed models. Stronger stimuli increased both likelihood and duration, but most variation was structured across species, colonies, and individuals.

The Nonpeptide Low Molecular Mass Toxins from Spider Venoms
, 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.

Children &Society, EarlyView.ABSTRACT Modern deaths have become reiterations. That is, despite exhibiting a seemingly high‐level of diversity in death's representations in everyday lives, death suffers from a particular onto‐epistemological poverty that prevents it from being imagined otherwise.

Beyond formic acid: Peptides in carpenter ant venoms aid in disease protection. [PDF]
Venom peptides are key to the evolutionary success of most venomous animals, including stinging ants. The stingless ant subfamily Formicinae is thought to rely solely on formic acid in their venoms, despite early, unsubstantiated hints of proteinaceous ...

Organic and Peptidyl Constituents of Snake Venoms: The Picture Is Vastly More Complex Than We Imagined [PDF]
, 2018 Small metabolites and peptides in 17 snake venoms (Elapidae, Viperinae, and Crotalinae), were quantified using liquid chromatography-mass spectrometry. Each venom contains >900 metabolites and peptides.

, 2020 Snake venoms contain components selected to immobilize prey. The venoms from Elapidae mainly contain neurotoxins, which are critical for rapid prey paralysis, while the venoms from Viperidae and Colubridae may contain fewer neurotoxins but are likely to ...

The effect of caste, mass and colony identity on rescue priorities in the red imported fire ant
Ecological Entomology, EarlyView.Fire ants will rescue brood when the brood becomes trapped underground. We find that rescuers may use odor cues to locate trapped rescue targets. We demonstrate that a single reproductive larva is preferentially rescued over a single worker larva, but that caches of multiple worker larvae receive equal treatment as a single reproductive larva.

Toxins, 2016 Natural products, sources of new pharmacological substances, have large chemical diversity and architectural complexity. In this context, some toxins obtained from invertebrate venoms have anticonvulsant effects.
