No evidence for Bergmann's rule in Otodus megalodon

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract It has been proposed that Otodus megalodon exhibits a Bergmann‐like size pattern, with individuals growing larger in cooler waters, an interpretation used to challenge the existence of fossil nursery assemblages. Here, we reanalyse the dataset used to support this claim, restricting analyses to upper anterior teeth to control for dental ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Passive transponder implantation in Theraphosidae: A tool for traceability and conservation

open access: yesInsect Conservation and Diversity, Volume 19, Issue 4, Page 737-745, July 2026.
PIT TAG microchip implantation was successfully performed in multiple tarantula species, showing high tolerance, rapid recovery from anaesthesia and no mortality associated with the procedure. Microchips remained stable and detectable after successive ecdysis events, with no negative effects on feeding behaviour, development, courtship, mating success ...

Contrasting Forest Trajectories Drive Changes in Bird Functional Traits

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim We investigated how bird functional diversity varies across forest habitat types with distinct successional trajectories, namely (1) natural succession forests, with naturally regenerating forests established on former grasslands; (2) secondary forest remnants resulting from deforestation; and (3) conserved forests.
