Summary: Shark fin soup is a popular dish consumed by Asian communities worldwide, driving the demand for shark fins and leading to a decline in shark populations by up to 70%. This research used molecular techniques to identify shark species in bowls of soup collected in Singapore and found endangered species with high levels of mercury. The consumption of shark fin soup likely exposes consumers to unsafe levels of mercury and further contributes to the decline of global shark populations.

Summary: This study used various diversity metrics to examine the diversity patterns in the Sunshine Coast heathlands. It found that the heathlands have low phylogenetic diversity and highlighted the presence of geographically scattered but compositionally similar sites, suggesting the existence of a potential refugial environment. The results of this study have important implications for conservation priorities.

Summary: Identifying breeding grounds is crucial for sustainable fisheries management. This study identified the potential breeding ground of Mugil cephalus in the Karanja estuary of the North Mumbai coast. The results revealed a potential spawning ground and emphasized the usefulness of DNA barcoding in identifying fish spawning grounds.

Summary: In this study, the hydrodynamic interaction between the large crescent dorsal fin and caudal fin in tuna was numerically explored. The presence of the dorsal fin substantially enhanced the thrust on the caudal fin, and a constructive interaction between the leading-edge vortex on the caudal fin and the vortices shed from the dorsal fin was identified. The flapping phase of the caudal fin and the Strouhal number had an influence on the dorsal fin-caudal fin interaction, while the Reynolds number did not have a substantial effect.

Summary: The paper presents the first report of Kandelia candel, a rare mangrove species, from Bhavanapadu, a coastal village in Srikakulam district, Andhra Pradesh, India. Only found in Bhavanapadu, this species is relatively less abundant along the east coast of India. The study emphasizes the importance of monitoring and protecting mangroves.

Summary: This study investigated the gut-associated bacterial communities in four fish species from Aghien lagoon, Ivory Coast. Species-related differences were identified, attributed to host phylogeny and diet. Variations throughout the year were observed in two fish species, highlighting the importance of time-series sampling. Fish act as major reservoirs of bacterial diversity, suggesting their contribution to the overall stability and resilience of bacterial communities in the lagoon.

Summary: The Atlantic Goliath Grouper, the largest grouper in the western North Atlantic, is highly vulnerable to fishing due to its slow growth rate and late maturation. The fishery monitoring for age determination typically relies on otoliths, but these are unavailable from Goliath Grouper due to a harvest moratorium. The study explores alternative structures such as dorsal fin rays and fin spines for age estimation, with the aim to accurately assess the population age structure and support management measures.

Summary: The interaction between the caudal fin and a distinct-shaped median fin in fish-like propulsion is studied in this paper. The enhancement of the caudal fin leading-edge vortex is investigated through the interaction with vortices formed upstream. The study uses high-speed videos and particle imaging velocimetry to visualize the fish's undulatory kinematics and flow behavior.

Summary: DNA barcoding has emerged as a scientific breakthrough in plant identification and conservation, especially in the field of medicinal plants. This study focused on analyzing the effectiveness of different DNA barcoding regions for Indonesian medicinal plant identification, with matK being recommended as the main region. Findings from this study have implications for forensic studies and the conservation of medicinal plants on a national and global scale.

Summary: In order to study the use of gold nanoparticles in miniature painting, seven 19th century portraits were examined, and the presence of Purple of Cassius pigment was confirmed in four paintings. The particles were characterized using X-ray powder diffraction and environmental scanning electron microscopy, with an average size of 8-14 nm. Replication of the pigment preparation in the laboratory yielded a similar pigment, providing new insights into the use of Purple of Cassius in portrait miniatures.

Summary: The taxonomy of the Pheidole pulchella species group in the Afrotropical region has been updated in this study, with the description of a new species P. klaman sp. nov. An updated identification key for the entire group and the known distribution ranges of its members have been integrated into the existing taxonomic system. High-quality focus stacking images and X-ray micro-CT scanned digital 3D representations of major and minor worker type specimens are provided.

Summary: This study investigated the functional potential of lactic acid bacteria (LAB) isolated from the gut of Tilapia originating from an aquaculture farm in Ivory Coast. The LAB strains exhibited high antagonistic activity against bacterial pathogens and strong survivability under low pH and bile salt conditions. Therefore, these LAB strains are recommended for future food and feed applications.

Summary: This study investigated the bioactive compounds and antioxidant activities of two industrial beers (maize and rice) in Cote d'Ivoire. Results showed that the antioxidant activities were higher in rice beer compared to maize beer, and the phenolic compounds were responsible for the antioxidant activities. Overall, beer consumption could have health benefits, but further research is needed.
