Ecology and Evolution, Volume 16, Issue 4, April 2026.Some fern gametophytes can explore new habitats that differ from their sporophyte counterparts, and when they do this, they tend to follow specific axes of climate related to aridity (increased or decreased). Moreover, we found that this ecological niche expansion may be driven by ecophysiological adaptations to abiotic environments.

Ecology and Evolution, Volume 16, Issue 4, April 2026.In the marine amphipod Caprella kominatoensis, males perform infanticide to terminate maternal care and accelerate female molting for mating opportunities. However, we found that maternal defense is effective when the female parent is larger than the intruding male.

Woodlands Facilitate Reproductive Behaviour and Niche Partitioning in Farmland Bumblebee Communities
Ecology and Evolution, Volume 16, Issue 4, April 2026.We sampled farmland bumblebees from habitats largely neglected in European pollinator studies: woodland understories and canopies. Light‐sensitive species and the reproductive castes showed the highest relative activity in shaded woodland understories, with reproductives increasing their use of this habitat during the hottest weather.

Breaking Boundaries: First Observation of Intertidal Emergence During Mating in Octopuses
Ecology and Evolution, Volume 16, Issue 4, April 2026.We document the first recorded case of intertidal emergence during copulation in Callistoctopus macropus. A mating pair gradually moved from shallow water onto the rocky shore while remaining attached, with the female resisting and the male counter‐anchoring for nearly 20 min before re‐submerging.

Long‐Term Evolution Under Heatwave Conditions in the Seed Beetle, Callosobruchus maculatus
Ecology and Evolution, Volume 16, Issue 4, April 2026.Here, using the seed beetle, Callosobruchus maculatus, we investigated the long‐term effects of evolution after 43 generations of fluctuating temperature with added heatwave exposure on two important life history traits, development time and lifetime reproductive success (LRS).

Molecular Reproduction and Development, Volume 93, Issue 4, April 2026.ABSTRACT Growth differentiation factor 9 (GDF9) plays a key role in enhancing developmental competence and blastocyst yield during in vitro maturation (IVM). This study investigated whether GDF9 could counteract the harmful effects of lipopolysaccharide (LPS), a gram‐negative bacterial component, on bovine in vitro embryo production, while also ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

TAXON, Volume 75, Issue 2, April 2026.Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Developmental environment and age shape macronutrient allocation to eggs and ejaculates
Functional Ecology, Volume 40, Issue 4, Page 1033-1045, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental conditions during development can have lasting effects on reproductive investment, but the sex‐ and age‐specific nature of such effects remains poorly understood.
