Summary: This study found that temperature influenced the reproductive output of axolotl salamanders, with higher temperatures leading to decreased egg and testis production. It suggests that males and females should be reared at different temperatures to optimize reproductive output. In addition, the reintroduction and translocation of axolotls should consider water temperature as an important component in conservation efforts due to their sensitivity to high temperatures.

Summary: Gonadal histological analysis of Carcinus maenas in Portugal reveals significant differences in gonad weight, gonadosomatic index, and oocyte diameter among different locations, suggesting geographic variations. A proposed macroscopic scale based on histological analyses provides a more accurate classification of ovary development stages.

Summary: The reproductive characteristics of oriental sole in the Persian Gulf were studied from August 2015 to July 2016. The fish showed a multiple spawning pattern with two prolonged spawning seasons. The males and females had different age ranges and the sex ratio was 1:2.2.

Summary: Low salinity has negative effects on reproduction in estuarine bivalves. It delays gametogenesis and spawning in oysters, except in June when low salinity promotes earlier gametogenesis. The findings suggest that low salinity not only affects the timing of reproduction but also extends the reproductive season.

Summary: The study aims to describe the reproductive cycle of Holothuria mammata in a coastal area of southwest Portugal. The research found that H. mammata had a sex ratio of 1:1.2 (male:female) and a size at first maturity of 142 mm for males and 167 mm for females. Gonad development started when days had a shorter photoperiod and lower seawater temperature, and spawning occurred later, with longer photoperiod and higher seawater temperature and chlorophyll-a concentrations. This study is essential to increase the biological and ecological knowledge of H. mammata populations and create conditions for their domestication and conservation measures.

Summary: The morphological, histochemical and ultrastructural aspects of ovarian development in three phenotypes of Macrobrachium amazonicum were analyzed. Despite the morphological differences and different reproductive strategies adopted by the females, the patterns of ovarian development showed no differences between the phenotypes.

Summary: The study found that male Acridoidea with relatively long wings have higher flight muscle weight, while females with relatively short wings have higher gonadosomatic index. Individuals with long wings have higher flight capability but lower reproduction, supporting the trade-off between flight and reproduction in Acridoidea.

Summary: This study describes the reproductive cycle of Lepidorhombus boscii in the eastern Adriatic Sea. The sex ratio of L. boscii was 1:0.89 (female:male), and the size at first sexual maturity was 19.2 cm for females and 20.3 cm for males. Previtellogenic and vitellogenic oocytes are present in the ovaries throughout the year. L. boscii has a prolonged spawning season in the Adriatic Sea with the main spawning season between November and March.

Summary: This study investigated the effects of stock density on a commercially valuable species of sea cucumber in the Mediterranean Sea and eastern Atlantic. Results showed no significant differences between density treatments in most parameters, except for mean oocyte diameter, with individuals in higher-density treatment exhibiting signs of increased vitellogenic reserves.

Summary: In vitro gametogenesis (IVG) has significant potential in the field of germ cell biology for understanding human infertility, conservation of endangered species, and genetic selection of livestock. Overcoming technical challenges and understanding the ontogeny and developmental programme in different species are crucial for realizing this potential. Differences in germ cell determination and epigenetic reprogramming between mice and other animals must be taken into consideration when developing IVG protocols.

Summary: Methylparaben (MeP), commonly used in daily products as a preservative, has become a concerning aquatic pollutant. This study exposed adult zebrafish to different concentrations of MeP to investigate its reproductive toxicity. The results showed that MeP exposure affected gonad development, disrupted hormone balance, and led to developmental deficits in offspring. This study provides insight into the antiestrogenic activity and reproductive toxicity of MeP.

Summary: This study examined the cyto-embryological characteristics of wild Kentucky bluegrass germplasm from Gannan and Longnan in Gansu Province. The research found no significant differences in pollen characteristics and viability between the two germplasm materials. The main apomixis observed was apospory, resulting in the coexistence of multiple embryo sacs, and polyembryonic seeds were frequently observed in Kentucky bluegrass.

Summary: This study aimed to determine the minimum legal size and appropriate closed season for the lobster population of Saint Kitts and Nevis by assessing and comparing the functional, physiological and morphological determinants of sexual maturity. The research found that females did not reach functional maturity until 87.8 mm carapace length (CL), but reached morphological maturity at 72.5 mm CL, and physiological maturity at 82.8 mm CL.

Summary: This study describes the reproductive cell development and ovarian developmental stages of white shrimp (Penaeus schmitti) caught off the southern coast of Espirito Santo, Brazil. The research identified non-germinal components and characterized five stages of gonadal development, providing essential information for understanding and promoting the reproductive aspects of penaeid shrimps.
