Summary: The relationship between individual growth rate and the timing of sex change plays a significant role in reproductive output and population productivity. Fast growth is associated with a younger age at sex change, but not necessarily a smaller size at sex change. Individuals that grow faster, particularly as large females, contribute more to population fecundity and ultimately obtain higher fitness.

Summary: The cleaning symbiosis between cleaner and client fishes is a remarkable mutualist marine interaction, contributing to the health of clients and the ecosystem. This study aimed to identify cleaning interactions as indicators of reef health in the Mexican Caribbean. Cleaning stations and attributes of cleaner and client fishes were located and described for three seasons in four locations. Bluehead Thalassoma bifasciatum was the dominant cleaner fish, interacting with 27 species of client fishes year-round. The frequency of client fishes varied with seasons and different species were favored. High-hat Pareques acuminatus was recorded for the first time as a cleaner. The number of cleaning stations was higher in areas with high human impact, but the diversity of client and cleaner species could be explained by higher structural complexity and reef area.

Summary: This study identifies neural circuits involved in courtship behaviors in bluehead wrasses. Stimulation of specific brain regions elicits color changes and movements similar to courtship behaviors, indicating the presence of male-typical sexual behavior circuits in females.

Summary: The macromorphology of olfactory organ in moon wrasse and sixbar wrasse was studied, revealing previously unknown structures such as the olfactory disk and vertical membrane. The distinct features of crest-folds in the disk, as well as differences in thickness and shape, were observed between the two species. The presence of a single large ventilation lacrimal nasal sac adjacent to the olfactory cavity and a proposed ventilation scheme were also discussed, suggesting potential methods for receiving olfactory information in wrasses when avoiding danger.

Summary: This study investigated the age distribution and growth properties of Symphodus cinereus in the south-eastern Black Sea. Data on the growth and age of S. cinereus were obtained from sagittal otoliths. A total of 384 specimens were collected and significant differences were seen in growth patterns between females and males. The maximum age recorded was 5 years.

Summary: This study used stable isotope analysis to show that Canada lynx primarily feed on snowshoe hares in all regions, but will switch to alternate prey when hare availability is low. These findings support the facultative specialist hypothesis, suggesting that specialist predators expand their diets when preferred prey are limited.

Summary: Facultative epiphytes play an important role in montane forest ecosystems, adapting to varying nutritional conditions between ground and canopy habitats. They exhibit different nutrient limitation strategies in different habitats, with epiphytic individuals showing more pronounced N limitation and using luxury consumption of nutrients while terrestrial individuals are more conservative in nutrient use. Facultative epiphytes maintain stable metabolic leaf activity through variable element concentrations in roots to adapt to heterogeneous forest habitats.

Summary: This study evaluated the taste preferences of the herbivorous African cichlid fish Nile tilapia and found that 21 out of 38 substances were palatable to the fish. The attractiveness of amino acids was species-specific, not related to dietary requirements, and did not correlate with the palatability of sugars. The feeding behavior and orosensory evaluation patterns of Nile tilapia were characteristic and may be linked to their social lifestyle.

Summary: A total of 326 parasitic helminths were obtained from 94 specimens of Halichoeres bivittatus in Veracruz, Mexico. Three species were found in the intestines, with one being a new geographical record and one being a new host record. The species richness and diversity index were lower than previous estimates in the study area.

Summary: The increasing marine microplastic pollution has negative effects on organismal physiology and ecosystem functioning. However, the potential responses of large benthic foraminifera (LBF) are largely unknown. This study found that the LBF species Amphistegina gibbosa can selectively feed on Artemia and avoid pristine microplastic particles, but conditioned microplastic has a similar feeding interaction rate as Artemia. This suggests that microplastics with longer residence times may have a larger impact on facultative detritivores.

Summary: Due to global warming, the increasing number of dead fish has caused significant economic losses in mariculture production. Anaerobic digestion (AD) is the most suitable method for treating dead fish waste (FW) as other organic waste treatments can lead to environmental issues. However, the ammonia generated from the protein degradation of FW poses challenges for start-up. This study investigated a proper start-up strategy for FW AD.

Summary: Consumption of red meat provides essential nutrients to human diet, and dietary and genetic manipulation of livestock can optimize the nutritional value of meat products. Future studies should aim to balance potential impacts on product quality and consumer perception in order to enhance the nutritional value of meat. Emerging fields such as phenomics, nutrigenomics, livestock precision farming, and systems biology may offer opportunities to improve the nutritional value of meat under both experimental and commercial conditions.

Summary: Colombian woolly monkeys, one of the largest primate species in the Americas, have selective foraging strategies that respond to changes in resource availability. They mainly feed on fruits but also consume a significant amount of arthropods. Fruits are the most important resource in their diet, followed by arthropods. Feeding time on fruits and arthropods is positively related, suggesting an optimal strategy to maximize nutrient intake.
