Summary: Optimal fertility in food-producing animals can be achieved by using exogenous GnRH and agonists to control ovulation timing and promote reproductive success. GnRH administration is used to counter ovarian dysfunction, induce ovulation, and increase conception and pregnancy rates in animals. Exogenous GnRH products are commonly used in pre- and post-breeding programs to enhance fertility and treat reproductive morbidities.

Summary: The study found that Holotrichia oblita females laid more eggs at 8:16 (L:D) h and 0:24 (L:D) h photoperiods, and food intake affects the number of eggs laid. A long scotophase is beneficial for greater oviposition in H. oblita.

Summary: Photoperiod plays a role in controlling fish reproduction, and melatonin acts as an internal transducer of environmental photoperiod. The present study investigates the impact of melatonin on the transcript levels of several genes in the brain of the sapphire devil fish. It was found that melatonin treatment can inhibit the increase of certain gene transcripts, and the expression of these genes fluctuates with the day/night cycle.

Summary: Food availability is an important factor that affects population size, community structure, and life-history traits of species. The timing of food availability has direct and indirect effects on the physiology and behavior of organisms, and can constrain reproductive output. The availability of food can shape the activity of the genome, but the functional linkage with epigenetic control of physiology is still not fully understood.

Summary: This study isolated two GnRH variants and four GnRH receptors from grass carp and found that GnRHR4 was highly expressed in the pituitary gland. Further investigations revealed that GnRH2 and GnRH3 regulated the expression of reproductive hormone genes and anorexigenic peptide genes in grass carp pituitary cells through multiple signaling pathways. Interestingly, food intake also influenced the expression of GnRH2 in the fish brain. These findings highlight the importance of GnRH in integrating feeding metabolism and reproduction in teleost.

Summary: The study found that VipA can both inhibit and induce LH secretion in zebrafish, suggesting the possibility of redundant pathways for LH release. The administration of VipA increased plasma LH levels, indicating that VipA may induce LH release through interaction with non-GnRH factors. These findings provide new insights into the regulation of LH secretion in zebrafish.

Summary: Many organisms use environmental cues to adjust the timing of events in their annual cycle, but our understanding of how these cues are integrated to generate observed seasonal timing patterns is still limited. This article presents a framework to describe the variation in cue integration and summarizes empirical findings across different species and life cycle events. A theoretical model is also used to explore how variation in cue integration may affect the adaptability of organisms in adjusting phenology in the face of climate change.

Summary: The study evaluated the reproductive performance of gilts using fixed-time artificial insemination (FTAI) protocol. The results showed that gilts treated with altrenogest for 18 days, followed by administration of GnRH 120 hours after altrenogest withdrawal and double fixed-time AI, had similar conception rate, farrowing rate, and litter performances compared to gilts inseminated at oestrus with conventional AI.

Summary: The male effect is a common reproductive management practice in goat farming, where the introduction of males to anovulatory females induces estrous activity within a few days. High testosterone concentrations are traditionally believed to be essential for a good reproductive response from female goats, but this study shows that testosterone levels can be stimulated in bucks after a period of isolation, and high testosterone concentrations are not necessary for a good response to the male effect in anestrous females.

Summary: Social interactions can play a key role in modulating the impact of stressful experiences. Social buffering and stress contagion are two interrelated processes involving the transmission of social information, suggesting similar neural mechanisms. Further research is needed to directly compare neural mechanisms during stress contagion and stress buffering processes.

Summary: Domesticated mice and rats are powerful model systems for biomedical research, but the California mouse is becoming increasingly popular for studying human-relevant behaviors. However, limited knowledge about species-specific housing needs may affect the results of studies. Different housing systems have sex-specific effects on California mouse behavior, with increased social and environmental complexity impacting home cage behaviors in male and female mice.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
