Summary: Despite previous research, the structure of helminth communities among fish populations in the Azov-Black Sea region remains poorly understood. This study presents data on the species diversity and structure of helminth communities in 12 common fish species from the coastal waters off Crimea. The communities showed low species richness and diversity indices, but were well-aggregated and followed a core-satellite distribution. These findings expand our knowledge and have implications for monitoring and managing local fish stocks.

Summary: The temporal variation of helminth infracommunity structure in Trachinotus rhodopus was studied offshore in Puerto ' Angel, Oaxaca (Mexican Pacific) in 2018. A total of 110 specimens were examined, and six species and three genera of helminths were identified using morphological and molecular data. Statistical analyses revealed stable richness of helminth infracommunities throughout the year, but variations in abundance were found related to seasonality, possibly due to parasite life cycles, host behavior, availability of intermediate hosts, and diet of T. rhodopus.

Summary: There is limited research on the impact of small hydropower stations on aquatic biodiversity. This study investigated the abundance of different organisms in the watersheds of 15 small hydropower stations in Qionglai City. The results showed that these stations had a significant but varied impact on plankton, benthic animals, fish, and microorganisms, with fish being the most affected.

Summary: This paper focuses on neglected tropical diseases caused by parasites and explores new therapeutic targets and lead compounds. It analyzes the interaction mechanisms between lead compounds and targets, as well as the signaling pathways associated with these diseases, in order to provide research ideas for potential anti-parasite compounds.

Summary: This study used 16S rRNA sequences and Illumina sequencing to characterize and compare the microbiota of Parascaris spp. The results showed differences in microbiota diversity between different organs of the parasites. Certain microbes, such as Veillonella and Sarcina, exhibited significant differences between groups. Comparing the microbiota of different Parascaris spp. specimens may provide potential targets for future parasite control options.

Summary: This study analyzed the distribution and structure of the parasitic infracommunity of six species of Hypostomus from the Ivai River. The results showed that the parasites exhibited similar infection patterns in all hosts, but there were differences in parasite species composition among different hosts. Hypostomus cochliodon and H. regani had the highest parasite richness, while Hypostomus sp.1 and Hypostomus sp.2 showed low abundance and intensity of parasitic infections. However, Hypostomus sp.1 had the highest values of evenness. These findings contribute to the knowledge about the parasitic fauna of Hypostomus spp. from the Ivai River by presenting new hosts and locality records.

Summary: This study evaluates the parasitic fauna of the commercially important Atlantic anchoveta, Cetengraulis edentulus, in the southeastern Brazilian coast. The study identifies eleven species of parasites, with the nematode Hysterothylacium sp. being the most abundant. Hysterothylacium sp. shows positive correlation with the host's total length and parasite abundance and prevalence, and its abundance is significantly higher in female hosts. This is the first report of C. edentulus acting as the host for nine species of parasites.

Summary: Our study in a shallow High Arctic kelp bed in the Beaufort Sea, Alaska, examined patterns of propagule recruitment to assess succession timescale and trajectory. We found that bottom waters remain frozen with low light levels for 8-9 months, while summer period is characterized by higher temperatures and measurable irradiance. Spatial differences in epilithic assemblages were observed, with a positive correlation between cover by crustose coralline algae and distance to river inputs.

Summary: Species interactions can affect spatial dynamics, especially when one species' movement depends on the presence of another. In a diverse community of arthropods associated with red wood ants, it was found that certain obligate myrmecophiles preferentially moved with the host ants, ultimately impacting community succession. Movement in symbiont communities of social insects may be heterogeneous and functional group-dependent, but is clearly influenced by host movement.

Summary: This study assessed the ecological status of mangrove wetlands in Hainan, China following anthropogenic activities. The results showed spatial and seasonal variations in benthic macroinvertebrate communities, with lower species numbers and richness in the southern mangroves. More than half of the mangrove habitats on Hainan Island were found to have poor to moderate ecological quality. The study recommends long-term monitoring and holistic approaches to effectively manage and conserve disturbed mangroves.

Summary: This study sampled two tropical estuaries in Northwest India for two consecutive years, and assessed the taxonomic and functional structures of macroinvertebrates. The study found that natural factors such as salinity and sediment grain size were the main drivers of variations in taxonomic and functional compositions. The multiple-trait approach was effective in evaluating the resilience of estuarine benthic ecosystems. Taxonomic diversity may not be an efficient proxy for benthic functioning.

Summary: This study investigates the significance of Labyrinthulomycetes protists (LP) in the biological pump, revealing their potential vertical export to the deep ocean and their niche partitioning in the pelagic ocean. The high diversity of LP communities and their multiple ecotypes suggest that they can be an important component of the biological pump through their various functions in organic matter transport and decomposition.

Summary: Three-dimensional shallow benthic complexity provides valuable information for coral reef conservation and management, as it reflects the physical conditions and biodiversity of shallow coral reef environments. This study mapped global shallow water benthic complexity using satellite images and found that high complexity regions are mainly concentrated in areas with high benthic biodiversity. However, a significant portion of coral reef regions with high benthic complexity remains unprotected. The global coral reef benthic complexity map generated in this study can contribute to improving marine protected areas, reef conservation, and management.

Summary: An integrated approach using three natural tags (microsatellites, parasites, otolith nucleus chemistry) proved effective in accurately distinguishing the population structure of spinyhead croaker into distinct northern and southern Chinese stocks. While individual natural tags had lower accuracy in assigning fish, the combination of all three tags showed good population structure differentiation capabilities.
