New PMCT multi‐indicator ossification standards for age estimation of the knee in modern Australian and North American children

Journal of Forensic Sciences, EarlyView.
Abstract Skeletal age estimation is crucial to medicolegal work, aiding subadult identification, and living age assessments in legal contexts. This study aims to document the ontogeny of knee skeletal indicators on post‐mortem computed tomography (PMCT), and quantify interpopulation variation between modern American and Australian children.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Exploring the potential of using male‐killing endosymbionts to induce female‐biased insect populations for enhanced biomass production

Insect Science, EarlyView.
Overview of the mindset and long‐term goals with the approach suggested in this study. We provide a first proof of concept that male‐killing endosymbionts can be used to establish female biased populations with higher production efficiency than populations with a 50/50 sex ratio. This biological tool can have marked positive impact on future commercial

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

Integrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

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

Integrative 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.
