Advanced Science, Volume 12, Issue 45, December 4, 2025.At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...

Action of ecdysterone on the moulting of amphipod females: Gammarus pulex (L.) and G.fossarum Koch. Early results. [Translation from: Crustaceana 28, 86-88, 1975.] [PDF]
, 1975 In studying sexual attraction in gammarids of the group pulex, it has seemed necessary to dissociate the processes of moulting and ovogenesis in order to recognize their respective effects on this phenomenon.

Ultrastructural studies of oogenesis in Bolinus brandaris (Gastropoda: Muricidae)
Scientia Marina, 2004 Ultrastructural studies of oogenesis in Bolinus brandaris are described. Although the initial phase of oogenesis is common to most animal species, vitellogenesis can be considered a species-specific characteristic.

A long-term copper exposure on freshwater ecosystem using lotic mesocosms: Individual and population responses of three-spined sticklebacks (Gasterosteus aculeatus) [PDF]
, 2007 Three-spined stickleback (Gasterosteus aculeatus) was used as the highest trophic level predator in an outdoor mesocosm study assessing the effect of environmentally realistic copper concentration (0, 5, 25 and 75 μg L−1) over 18 months of continuous ...

The Reproductive Season of the Highland Stoneroller, Campostoma spadiceum, Evidenced by Museum Specimens [PDF]
, 2019 The Highland Stoneroller (Campostoma spadiceum) was described as a distinct species in 2010. Since then, the only study specific to this species is a survey of distribution, and nothing is known about reproduction.
