On The Evolution Of The Spectral Break In The Afterglow Of Gamma Ray Bursts

open access: yes, 2012
The temporal evolution of the spectral break in the time resolved spectral energy density of the broad band afterglow of gamma ray bursts (GRBs) 091127 and 080319B was shown recently to be inconsistent with that expected for the cooling break in the ...

Pests for Dinner: Dietary Composition of Insectivorous Bats in a Fragmented Tropical Dry Forest

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Insectivorous bats are key predators of a wide array of arthropods, including species that act as disease vectors and pests, yet such ecological roles remain poorly studied in tropical regions. In this study, we aimed to describe the diet of five insectivorous bat species from the genera Balantiopteryx, Myotis, Mormoops, and Pteronotus inhabiting a ...

Cicada as a food for mammals: a global review and implications for mammal behaviour and populations

open access: yesWildlife 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.

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

open access: yesSystematic 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

The birds and the trees: Avian ecosystem (dis)service perspectives and farmers' willingness to plant native trees in the agricultural landscape of the Galapagos Islands

open access: yesPeople 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 ...

open access: yes, 1999
Recent observations suggest that gamma ray bursts (GRBs) and their afterglows are produced in star formation regions in distant galaxies by highly relativistic jets that happen to point in our direction.
