Could photoperiodic responses have evolved before the emergence of circadian clocks?

New Phytologist, Volume 248, Issue 6, Page 2707-2713, December 2025.
Summary Plants use photoperiod (i.e. day length) as a seasonal cue for timing when to flower. This ability, known as photoperiodism, also underlies phenomena such as migration, seasonal reproduction, and hibernation in animals. Because a circadian (daily) clock underlies the day/night length timing mechanism in most organisms, it has been generally ...

Growth–survival trade‐off in temperate trees is weak and restricted to late‐successional stages

Journal of Ecology, Volume 113, Issue 11, Page 3466-3477, November 2025.
Our findings highlight a role of disturbances in filtering life‐history strategies and their potential impact on forest dynamics and global carbon cycling, but also a need to better understand the mediating processes of tree demographic trade‐offs.

Dietary Phosphorus Requirement for Tambaqui, Colossoma macropomum, in the Grow‐Out Phase

Journal of Animal Physiology and Animal Nutrition, Volume 109, Issue 6, Page 1321-1332, November 2025.
ABSTRACT Phosphorus is essential for fish growth as it is crucial in skeletal development and metabolic reactions. The dietary requirement for this mineral varies among fish species and growth stages. Therefore, the objective of this study was to determine the available phosphorus (AP) requirement for tambaqui during the grow‐out phase (± 400 to 1000 g)
