Rapid Gamete Maturation and Social Modulation Shape Reproductive Dynamics in a Brood Parasitic Catfish

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Obligatory brood parasitism in the Lake Tanganyika cuckoo catfish requires rapid reproductive readiness to exploit unpredictable host spawning. Our experiments showed that males are almost continuously ready to reproduce, while females ovulate about once a week, with social interactions enhancing gamete maturation in both sexes.

Investigating the Modality and Signalling Principles in Immersive Augmented Reality Learning Environments

Journal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background The potential of Augmented Reality (AR) for enhancing learning has long been discussed, however, existing research primarily relies on media comparisons that provide little basis for robust theoretical development. The Cognitive Theory of Multimedia Learning (CTML) proposes design principles for learning materials to support ...
