Summary: The study provides empirical evidence of range expansions in two native freshwater fish species, Spotted Gar and Spotted Sucker, observed in Lake Erie. Using mtDNA barcoding and phylogenetic analyses, the researchers confirmed the species identifications and found no correlation between increased detection rate and sampling effort. The historical habitat degradation in eastern Lake Erie has been hypothesized to be remediated, leading to suitable habitat for the species to recolonize shallow waters.

Summary: This study examined the associations between landscape pattern and river water quality in an agricultural basin in western China. The results showed that urban-related landscape metrics had the highest impact on water quality degradation, followed by cropland-related metrics. Landscape metrics had a better explanatory power for water quality variations in the wet season. The threshold values of certain landscape metrics, such as the percentage of urban land and the largest patch index of urban land, were identified to control pollution.

Summary: This study evaluated the expression of CYP1A in twelve different species of freshwater fish from various bodies of water in western NY. The results suggest possible adaptation of fish to pollution in the Tifft Nature Preserve and Genesee River, while CYP1A expression in fish from other lakes and rivers represents known pollution levels.

Summary: The study aimed to investigate the impact of meso-scale eddies in the western South China Sea on species composition and spatial patterns of fish larvae and juveniles. The results showed higher abundance of fish larvae in summer, mainly found near the eddies, while the distribution of fish larvae in autumn was more complex and influenced by multiple factors.

Summary: In this paper, more than 2000 Synthetic Aperture Radar (SAR) images of the Western Java Sea were analyzed to generate oil pollution statistics. The results showed that oil pollution mainly occurred along major shipping routes and at oil production sites, with most spills being small in size. When comparing the results obtained by different operators, it was found that there were differences due to lookalikes and overlooked small spills. The analysis also revealed that the percentage of spills identified by both operators increased when considering SAR images acquired at higher mean wind speeds.

Summary: The study developed a simple and eco-friendly method to synthesize high-activity cobalt nanoparticles encapsulated in N-doped carbon networks, which exhibited better oxygen reduction reaction activity compared to commercial platinum catalysts, holding great potential for the commercial application of zinc-air batteries.

Summary: This article presents a rare case of intraductal carcinoma (IDC) of the salivary glands, which was examined immunohistochemically and genetically. The final diagnosis was a high-grade mixed intercalated duct/apocrine-type IDC of the upper lip. The article also discusses diagnostic challenges related to minor salivary gland lesions and the basal-like phenotype of this particular case.

Summary: Recent discoveries of cryptic diversity among Gammarus fossarum species complex in the Western Carpathians pose a challenge for understanding their coexistence. This study found that the distribution of divergent lineages of Gammarus fossarum was influenced by river network position, altitude, stream width, and anthropogenic stress, but not by mesohabitat flow rates. Despite highly imbalanced lineage ratios, strong prezygotic reproductive barriers exist between the studied lineages, indicating the absence of recent gene flow. The frequent and temporally stable syntopy of these reproductively isolated lineages warrants further research on the processes facilitating their coexistence.

Summary: By studying Cyrtodactylus species in northern and western Thailand, researchers have identified the geographic distribution patterns and phylogenetic relationships of these geckos. The results suggest a pattern of geographic separation and distribution of these species in the region, as well as evidence of hidden biodiversity.

Summary: Epithelial-myoepithelial carcinoma (EMCa) is a rare low-grade salivary malignancy, and it is rare for EMCa to occur as the carcinomatous component of carcinoma ex-pleomorphic adenoma (PA); our study of an 83-year-old female patient showed that EMCa ex-PA is characterized by a bi-layered structure consisting of inner ductal cells and outer myoepithelial cells at histological and genetic levels.

Summary: The study evaluated the hypothesis of negative interactions between red shiner and woundfin, showing a negative correlation between their abundances. However, other factors such as water quality may also have contributed to the decline of woundfin, indicating a need for further research to identify definitive causal mechanisms.

Summary: This study aims to assess the effectiveness of Sonar5-Pro for detecting and describing fish passages in a high fish diversity river in low flow conditions. The tool's accuracy was evaluated by comparing Sonar5-Pro outputs with manual analysis, showing it successfully detects fish moving into the detection beam and has a certain level of efficiency in detecting fish swimming direction.

Summary: The guild approach simplifies community analysis by aggregating species with similar roles or functions into groups, but inconsistencies and overlooking ontogenetic changes may still exist. New techniques and guidelines are developed to address limitations and facilitate objective guild creation.
