Breeders are less active foragers than non-breeders in wild Damaraland mole-rats

Biology Letters, 2020
Eusocial societies are characterized by a clear division of labour between non-breeding workers and breeding queens, and queens often do not contribute to foraging, defence and other maintenance tasks.

Effect of chop length of grass silage harvested at two maturity stages, and of concentrate protein level, on feed intake and milk production in dairy cows

Grass and Forage Science, Volume 79, Issue 2, Page 211-227, June 2024.
Abstract This study in dairy cow feeding explored the effects of growth stage and chop length for grass‐clover silage, and of concentrate protein level, including the interactions of these three factors. The experiment was conducted with 48 Norwegian Red cows according to a cyclic change‐over design with four 4‐week experimental periods and eight ...

Unprovoked Stabilization and Nuclear Accumulation of the Naked Mole-Rat p53 Protein

Scientific Reports, 2020
The naked mole-rat is a subterranean rodent, approximately the size of a mouse, renowned for its exceptional longevity (>30 years) and remarkable resistance to cancer. To explore putative mechanisms underlying the cancer resistance of the naked mole-rat,

More than one way to eat a mouse: Skull shape variation within a monophyletic group of mammals (Marsupialia; Dasyurinae)

Journal of Zoology, Volume 322, Issue 1, Page 76-88, January 2024.
We investigated the relationships between cranial shape and body size in the evolutionary context of the shift from insectivory to hypercarnivory in a monophyletic group of 16 dasyurine marsupial species. Non‐allometric pattern of skull shape reveals adaptation for different feeding strategies that is independent of absolute size.
