Hormones reflect the impacts of reproductive rest on subsequent pregnancy in a marine predator

Functional Ecology, Volume 39, Issue 12, Page 3417-3433, December 2025.
Read the free Plain Language Summary for this article on the Journal blog.

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.
