Spawning took place in April–May and generally not all eggs were spawned, a small proportion being kept as a reserve material for the following gamete production. The pelagic phase (trochophore and metatrochophore stages) was short (2–3 daysDaniela...
GnRH neuronal activity varies across the lifespan as is reflected by changes in gonadotropin levels and, ultimately, gonadal steroid and gamete production. In the human, GnRH is detectable in the hypothalamus by 10 weeks gestational age with FSH and LH produced by 10–13 weeks ...
Secondary sexual dimorphism (SSD) in flowering plants is expressed by sexual differences of characters that are not directly related to gamete production. The leaf C/N ratio, photosynthetic traits or clonal responses have never been studied in relation to SSD in yerba‐mate. It was hypothesized ...

SummaryAspects of sperm motility and metabolism are important for understanding gamete quality. The objectives of this study were to investigate changes in adenosine 5′-triphosphate (ATP), and lactate dehydrogenase (LDH) of Atlantic cod sperm over time following activation, and to determine if ...
After finding these micro-organisms in some populations of Diplolepis spinosissimae (Hymenoptera: Cynipidae) where they are responsible for thelytoky through gamete duplication, we searched for Wolbachia spp. using specific PCR primers in nineteen other species of the Rhoditini tribe (rose gall...
