Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

Mammal Review, Volume 55, Issue 3, July 2025.
ABSTRACT Animals experience seasonal fluctuations of photoperiod, food availability, temperature and precipitation. This affects their energy budget, often leading to seasonal reproduction. We review available literature and (re)‐analyse existing datasets on seasonal reproduction of South American caviomorph rodents that are characterised by long ...

Written in bones: palaeoclimate histotaphonomic history inferred from a complete Megatherium skeleton preserved in the Atacama Desert

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract A nearly complete and relatively well‐preserved skeleton of the giant ground sloth Megatherium sp. in the hyperarid core of the Atacama Desert reveals how climate related taphonomic processes drastically transformed these remains over time.

Telling the Seasons Underground: The Circadian Clock and Ambient Temperature Shape Light Exposure and Photoperiodism in a Subterranean Rodent

Frontiers in Physiology, 2021
Living organisms anticipate the seasons by tracking the proportion of light and darkness hours within a day—photoperiod. The limits of photoperiod measurement can be investigated in the subterranean rodents tuco-tucos (Ctenomys aff.
