Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Cold storage effects on immature calliphoridae: Survival limits and forensic consequences for PMI estimation

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract This study investigated the effects of continuous refrigeration (4°C ± 2°C and 50% ± 5% RH) on the development and survival of immature stages (eggs, first, second, and third instar larvae, and pupae) of four forensically important blowfly species (Chrysomya megacephala, Chrysomya putoria, Hemilucilia segmentaria, and Lucilia cuprina) compared

Structure determination of a 4-pyrone from the liverwort Plagiochila bifaria (Sw.) Lindenb. (Plagiochilaceae) [PDF]

open access: yes, 2008
The centenary of the presentation in 1907 of the "polyketide" hypothesis by Collie, along with his use of a 4-pyrone as an example, is marked by reporting the discovery and isolation of 2-(3,4-dimethoxyphenethyl)-6-methyl-4-pyrone from <i> ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

The Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

open access: yesIntegrative Zoology, EarlyView.
Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.
