Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

open access: yesMammal 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 ...

Diversidad de micromamíferos en tres ambientes de la Reserva Nacional Lago Peñuelas, Región de Valparaíso, Chile [PDF]

open access: yes, 2012
Chilean Mediterranean ecosystems, the only of this type present in South America of the four present in the world, are considered priority areas for conservation due to their high concentration of endemic species that have experienced accelerated rates ...

Environmental and genetic influences on early attachment [PDF]

open access: yes, 2009
Attachment theory predicts and subsequent empirical research has amply demonstrated that individual variations in patterns of early attachment behaviour are primarily influenced by differences in sensitive responsiveness of caregivers.

Two rodent suborders have evolved missing amino acids in the lipid‐binding region of apolipoprotein E

open access: yesLipids, Volume 60, Issue 3, Page 143-153, May 2025.
Abstract The order Rodentia comprises nearly 45% of all extant taxa, currently organized into 31 living families, some 450 genera, and roughly 2010 species (Kelt & Patton, 2020). Considering that rodents began evolving at least 66 million years ago, it is not surprising that they have diversified into five distinct suborders.

Flight initiation distance is repeatable and geographically flexible in greylag geese Anser anser

open access: yesJournal of Avian Biology, Volume 2025, Issue 3, May 2025.
The decision to flee from an approaching threat represents a trade‐off between the costs and benefits of flight. In research to date, particular interest has been given to the effects of urbanisation on predator escape behaviour. However, these differences are most often studied at the population rather than individual level, which makes it difficult ...

Spatial patterning of prey at reproduction to reduce predation risk: what drives dispersion from groups? [PDF]

open access: yes, 2016
Group living is a widespread behavior thought to be an evolutionary adaptation for reducing predation risk. Many group-living species, however, spend a portion of their life cycle as dispersed individuals, suggesting that the costs and benefits of these ...

Multilocus Sequence Typing Unveils Two Novel Genospecies of Borrelia burgdorferi Sensu Lato in Ticks Infesting Cricetid Rodents of Northern Chile

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Tick‐borne spirochetes of the genus Borrelia are maintained in enzootic transmission cycles involving wild vertebrates such as rodents. The genus includes the lyme disease group (LDG), transmitted by hard ticks (Ixodidae), and the relapsing fever group (RFG), mostly transmitted by soft ticks (Argasidae).

Editorial: Neurodegeneration: from Genetics to Molecules [PDF]

open access: yes, 2016
Chronic degenerative diseases are one of the major public health problems, particularly those affecting the nervous system. They are characterized by the degeneration of specific cell populations that include several pathologies which contribute ...
