Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

A pellet‐based approach for moss biocrust inoculation: high establishment under laboratory conditions, challenges in the field

Restoration Ecology, EarlyView.
Abstract Introduction Biological soil crusts (biocrusts) are key components of soil ecosystems and promising tools for ecological restoration. Mosses, as important biocrust constituents, contribute to ecosystem functioning but often fail to establish after inoculation due to harsh environmental constraints.

Preliminary study documents variable accuracy and inclusion among biology instructor gender/sex definitions

Natural Sciences Education, Volume 55, Issue 2, December 2026.
Abstract Society generally presents sex inaccurately as a binary variable based on one or few trait(s), causing myriad issues, including the pursuit of reductionist biology experiments, the creation of laws that limit the rights of women, people with queer genders, and intersex folks, and greater student endorsement of gender stereotypes in ...

Is facultative sex the best of both worlds in the parasitoid wasp Lysiphlebus fabarum?

Royal Society Open Science
The prevalence of sexual reproduction has long puzzled evolutionary biologists. This is because asexual parthenogenesis is a more efficient mode of reproduction, and all-else-being-equal, should predominate over sex.

Early Contributions Leading to Understanding the Significance of Epichloë Endophyte in Temperate Grasses

New Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
The role and use of Epichloë fungal endophytes in grazed temperate grass pastures and turf grasses are now well understood with regard to balancing pasture persistence while minimising animal health and welfare concerns. However, this understanding has only emerged since the early 1980s. Prior to this, although links between Epichloë endophytes, animal
