Unique venom proteins from Solenopsis invicta x Solenopsis richteri hybrid fire ants

open access: yesToxicon: X, 2021
The Solenopsis venom protein 2 transcript was amplified, sequenced, probed, and analyzed from Solenopsis invicta x Solenopsis richteri hybrid ant colonies (hybrids) collected from across Tennessee to determine the extent of introgression of each parent ...

Toxicity of Ant Venom, Further Studies of the Venom from Pogonomyrmex barbatus.

open access: yesExperimental Biology and Medicine, 1965
SummaryAs previously suggested from earlier and cruder extraction procedures (2) and as now verified, the actual venom material is far more toxic than the earlier homogenized agent. The present work indicates that 1.29 mg/kg of the relatively pure material is equivalent to 24 mg/kg of the abdominal homogenate utilized previously(2). The pure extract is

Magical Realist Hauntings in Children's Everyday Encounters With Death, or, How to Believe in Impossible Things

open access: yesChildren &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.

How a Traveling Exhibition on Wasps Altered Public Perceptions

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT Media portrays a caricature of the “evil” wasp (a flying insect), perpetuating fears developed at a young age or from individual negative experiences. Because wasps are critically important to nature and our agriculture, it is important to provide some form of education to lessen this fear.

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly

open access: yesEcological Entomology, EarlyView.
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

The Peptide Venom Composition of the Fierce Stinging Ant Tetraponera aethiops (Formicidae: Pseudomyrmecinae)

open access: yes, 2019
International audienceIn the mutualisms involving certain pseudomyrmicine ants and different myrmecophytes (i.e., plants sheltering colonies of specialized "plant-ant" species in hollow structures), the ant venom contributes to the host plant biotic ...

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

open access: yesEcological Entomology, EarlyView.
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.

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

open access: yes, 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.
