Cicada as a food for mammals: a global review and implications for mammal behaviour and populations
Wildlife Biology, Volume 2026, Issue 1, January 2026.Cicadas (Hemiptera: Cicadidae) are among the most important insect prey for many vertebrate predators, including birds and mammals, owing to their large size and high nutritional value. Although the ecological roles of cicadas as prey for birds have been well documented, the interactions between mammals and cicadas are relatively unknown.

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Fireball and cannonball models of gamma ray bursts confront observations
, 2005 The two leading contenders for the theory of gamma-ray bursts (GRBs) and their afterglows, the Fireball and Cannonball models, are compared and their predictions are confronted, within space limitations, with key GRB observations, including recent ...

People and Nature, Volume 7, Issue 12, Page 3182-3206, December 2025.Abstract Agricultural landscapes hold great potential for biodiversity conservation; however, this will require finding solutions that work for both people and nature. Increasingly, the conservation community is calling for more cross‐disciplinary research integrating ecological questions with social and behavioural sciences for a more complete and ...
