Summary: This study found that precipitation, instead of temperature, has shaped the evolution of life history in lizards, leading to larger maternal size and larger offspring. However, annual precipitation has a negative impact on offspring size, potentially due to the need to conserve water in dry environments.

Summary: The study found that the survival rate of solitary cavity-nesting bee larvae was higher in urban areas compared to surrounding rural areas due to decreased nest parasitism. Additionally, bee fecundity was found to increase with the proportion of native flowers in the surrounding floral community.

Summary: Batoids, including the Naru eagle ray, are among the most threatened species of sharks and rays. The reproductive life history of the Naru eagle ray reveals that females mature at a larger size and older age than males, with synchronized seasonal reproduction and matrotrophic histotrophy.

Summary: This study found that different strains of Leptospira spp. lead to different reproductive problems, with higher seroreactivity herds experiencing more reproductive issues. Sejroe serogroup was mainly associated with embryonic death, while Icterohaemorrhagiae serogroup was linked to abortions.

Summary: The estuarine crab Hemigrapsus crenulatus is widely distributed along the coast of the South Pacific Ocean. It serves as an important prey for snook fish and kelp gull, and has a diverse diet. Environmental conditions and human impacts along the Chilean coast can affect its reproductive traits and the elemental composition of its embryos, which in turn affect its biological fitness.

Summary: The study did not unequivocally confirm the hypothesis that Scotch broom in the invasive range in Lithuania outperforms plants in the native range in terms of reproductive traits. While potential fecundity was significantly higher in the native range, the realised fecundity showed no significant difference between the two ranges. The pod width was greater in the invasive range, indicating a potential relationship between reproductive traits and habitat type in different geographical regions.

Summary: This study analyzed the reproductive parameters of the European spiny lobster in two fully protected areas in Sardinia, Italy. The results showed that the population inside the protected areas had higher egg production over time, indicating the positive impact of the restocking program. The study highlights the importance of protected areas in fisheries management and conservation planning.

Entomology

Summary: Insect growth is interrupted by molts, during which the insect develops a new exoskeleton. Ecdysis, the shedding of the exoskeleton between each developmental stage, is triggered by Ecdysis triggering hormone (ETH) and plays a vital role in insect ecdysis. ETH binds to ETH receptor (ETHR) in the central nervous system (CNS) to facilitate synthesis of neuropeptides involved in ecdysis.

Summary: This study investigated the impact of a probiotic mixture on BPA-induced effects on reproduction in zebrafish. The results demonstrated that in fish exposed to the combination of BPA and probiotic, most transcripts were closer to control or probiotic-treated levels, suggesting the potential of the probiotic mixture to counteract BPA toxicity.

Summary: The article describes a method to determine embryonic viability and brood size in Caenorhabditis elegans. This technique can be used to assess errors in meiosis, fertilization, and embryogenesis and is easily adoptable for new researchers. It is an excellent model organism for studying these processes.

Summary: This study used the North Chinese grass lizard as a model to test the hypothesis that sexual size monomorphism occurs in lizards where reproductive performance is maximized at similar body sizes for both sexes. They found evidence of weak size-assortative mating, with reproductive performance maximized in intermediate-sized individuals of both sexes. Future research could investigate other sexually monomorphic lizard species in a phylogenetic context to further support this hypothesis.

Summary: The study showed that 3,4-DCA has reproductive toxicity on Javanese medaka, leading to low fecundity in female fish and alterations in gonadal tissues and gametes development. This finding emphasizes the importance of native species in monitoring the toxicity effects of chemicals in aquatic environments.

Summary: Plasticity in parental care investment allows organisms to respond to rapid environmental changes in marine ectotherms, with potential trade-offs between offspring survival and parents' fitness under ongoing ocean warming. The study found a decrease in parental care activity and hatching success under elevated temperatures, indicating potential cost-benefit trade-offs between immediate and longer-term fitness. Plasticity in parental care behavior may partially mitigate the negative effects of temperature-dependent impacts.

Summary: This study investigated the maturation of the ovarian portion of the ovotestes, mating viability, and embryonic development in Lysmata ankeri, an ornamental species widely exploited by marine aquariums. The research found that mating success was higher in hermaphrodite pairs compared to pairs with a male shrimp. Additionally, L. ankeri showed continuous reproduction with the production of viable larvae with a low yolk reserve.
