Abstract Despite the importance of the seasonal timing of events in the life cycle for understanding population dynamics, we lack information on the phenology of most macroalgal species. The red macroalga Gracilaria vermiculophylla has become common in both hard‐ and soft‐bottom habitats following its invasion throughout the Northern Hemisphere.

Hurdles in investigating UVB damage in the putative ancient asexual Darwinula stevensoni (Ostracoda, Crustacea) [PDF]
Ostracoda or mussel-shrimps are small, bivalved Crustacea. Because of their excellent fossil record and their broad variety of reproductive modes, ostracods are of great interest as a model group in ecological and evolutionary research.

Three Decades of China's Bt Cotton: Achievements and Insights
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.

Role of AMPK Throughout Meiotic Maturation in the Mouse Oocyte: Evidence for Promotion of Polar Body Formation and Suppression of Premature Activation [PDF]
This study was conducted to assess the role of AMPK in regulating meiosis in mouse oocytes from the germinal vesicle stage to metaphase II. Exposure of mouse cumulus cell-enclosed oocytes (CEO) and denuded oocytes (DO) during spontaneous maturation in ...

Mapping molluscan endocrinology: a systematic and critical appraisal
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Non‐Canonical, Somatic‐Dependent Vertical Transmission of Wolbachia in an Aphid
We discovered a novel somatic‐associated Wolbachia transmission strategy in cedar bark aphids (Cinara cedri), contrasting with its typical maternal vertical transmission. This unique maternally retained somatic re‐acquisition strategy—a “piggybacking” on the highly efficient obligate symbiont transmission pathway—reveals diverse endosymbiont strategies
