Unexpected Evolutionary Divergence of Tachykinin‐Positive Neurons Innervating the Central Complex in Hexapods

open access: yesJournal of Comparative Neurology, Volume 534, Issue 3, March 2026.
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.

Plant structural complexity and mechanical defenses mediate predator-prey interactions in an odonate-bird system. [PDF]

open access: yes, 2017
Habitat-forming species provide refuges for a variety of associating species; these refuges may mediate interactions between species differently depending on the functional traits of the habitat-forming species.

Consistent Trait Patterns in a Hyper Diverse Moth Clade Along a Western Himalayan Elevational Gradient

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study examines how Geometrid moth assemblages along a 1500‐m elevational gradient in the western Himalayas respond to temperature and air density shifts. While species diversity declines with elevation and turnover occurs from low to high elevations, no significant changes in morphological or flight traits were observed at the assemblage level ...

Clashing in Murky Waters: On Amphibian Mosquito Suppression

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study compares the predator efficiency of common European amphibian species to common invertebrate mosquito predators. Focusing on the cosmopolitan mosquito Culex pipiens, known for transmitting pathogens like West Nile virus, we assessed predator rates, sex‐specific efficiency in amphibians, and the impact of predator presence on mosquito ...

Evidence for Environment‐Specific Pace‐of‐Life Syndromes

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
The correlation between behaviour and life‐history depends on environmental conditions. We show this is true when considering the quality of the food in the environment. ABSTRACT The pace‐of‐life syndrome (POLS) hypothesis posits that consistent individual differences in behaviour are integrated with physiology and life‐history traits such that ...
