Summary: This study investigated the composition, guilds, and metabolic potential of mycoplankton communities in contrasting marine environments. It found that trophic status played a major role in determining the abundance of mycoplankton, with different fungal taxa dominating different sites. Environmental factors such as temperature, pH, and chlorophyll-a were strongly associated with spatial diversity patterns. The study broadens the understanding of taxonomic and metabolic repertoire of marine mycoplankton and shows how they are influenced by site-scale environmental heterogeneity.

Summary: Windstorms and salvage logging have significant impacts on soil-living arthropod communities in alpine spruce forests. This study used DNA metabarcoding to investigate the effects of wind-induced disturbances on these communities, revealing a decrease in abundance and richness of microarthropods in windfall sites. The species composition and functional guilds of microarthropods were also found to be different between disturbed and undisturbed forests. The study highlights the importance of considering environmental gradients in understanding the responses of arthropod communities to forest disturbance.

Summary: The global increase in population has raised food demand, leading to aquaculture as a solution to hunger and poverty. However, sustainable aquaculture development is hindered by limited resources and environmental impact. Biofloc technology offers a promising solution with high productivity, reduced resource usage, and minimal environmental impact, making it a viable option for sustainable aquaculture.

Summary: The integration of bioremediation systems is a promising technique to reduce the environmental impact of aquaculture effluents, allowing for nutrient recycling and high-value by-product creation. Halophyte plants, such as Sarcocornia neei, have shown high efficiency in removing nutrients from marine aquaculture wastewater. Further studies should investigate the growth rates and nutrient removal efficiency of S. neei under different conditions for potential industrial-scale applications.

Summary: The study revealed similar levels of genetic diversity between cultured and wild fish populations. Global genetic differentiation was low, indicating that genetic variation mainly occurred within populations. However, a reduced contemporary effective population size was observed in farmed fish populations, possibly reflecting a bottleneck caused by founder effect.

Summary: This study explored the internal cycling process of nitrogen and phosphorus in traditional aquaculture ponds. It was found that excessive phosphorus limited the hydrolysis of organic phosphorus but promoted the production of harmful ammonium nitrogen. Balanced nitrogen and phosphorus management measures were recommended in aquaculture ponds during the farming period.

Summary: Bird counting suffers from imperfect detection, and this study found that the detection rate is influenced by species abundance but not body mass. Different habitats and time periods also affect the detection rate, with insectivorous species showing higher detection rates in farmland and afternoon. Cloudiness does not affect the overall detection rate, while temperature and wind affect some guilds' detection rates.

Summary: In Chile, the environmental risks of escaped non-native salmonids vary among species, with Atlantic salmon having the lowest risk due to lower survival, feeding ability, and reproductive capacity in the wild. The overall risks are highest in areas with high farming intensity and low ability to mitigate escapes, such as the Aysen District. Risk is also higher in areas with high farming intensity and suitable habitats for reproduction and rearing of juvenile salmonids.

Summary: Seafood plays a significant role in achieving a sustainable food system. This study investigates the use of a novel single cell protein feed ingredient, based on a side stream from the forest industry, to replace soy protein concentrate in rainbow trout farming. Results show that the inclusion of this ingredient significantly reduces biodiversity impact and greenhouse gas emissions.

Summary: This study found that the frequency and intensity of hurricanes have increased due to climate change, affecting species diversity. The study analyzed the diversity of bat species in coastal Jalisco, Mexico, with different levels of anthropic disturbance. It was discovered that the time after a hurricane and the seasons had significant effects on the abundance of bats.

Summary: Impoundments caused by dams have significant impacts on the physical, chemical, geomorphological and hydrological characteristics of rivers, leading to declines in freshwater biodiversity. This study used trait-based analysis to evaluate the effects of dam cascades on fish functional diversity. The results showed that the cascade of dams resulted in functional homogenization of fish fauna, particularly for detritivorous species.

Summary: Human pressures have a worldwide impact on freshwater ecosystems. This study assessed the effects of human pressure on habitat diversity and primary productivity in tropical and subtropical streams, and found that increased human pressure directly decreases habitat diversity and indirectly affects fish fauna. Streams with higher human disturbance had lower habitat diversity, higher primary productivity, and higher abundance of non-native species.

Summary: The present study aims to investigate whether cage fish farming has caused functional impoverishment of local ichthyofauna, and whether modifications in functional diversity are mainly related to the diet of the fishes, as well as whether cage fish farming has caused taxonomic re-structuring of the local ichthyofauna. Through the analysis of three indicators, it was found that the fish community in the fish farm area had significantly lower functional diversity and homogenization of eating habits, and there were changes in the structure of the ichthyofauna caused by different dispersions of species abundance between areas. This study highlights the necessity of using different evaluation methods and multifaceted diversity approaches to evaluate the environmental impact of fish farming.

Summary: This study investigated the effects of a drought followed by a flood period on the attributes of ichthyofauna in an aquaculture and in a control area in Southeast Brazil. The results showed that the aquaculture area remained stable in both seasons, while the control area exhibited changes in species richness and diversity. These changes in the control area were possibly due to the availability of new areas and resources during the wet season caused by flooding. The aquaculture community, on the other hand, was less affected by the flood due to the continuous habitat structure provided by the enterprise.

Summary: This study investigated the parasitic fauna and diet of S. maculatus in a hydroelectric reservoir in Brazil and performed two literature reviews. The results revealed that S. maculatus has a piscivorous feeding habit, a low richness parasitic community with two taxa of monogeneans as the most prevalent group, and no endohelminths observed. Data analysis from the literature and this study showed that S. maculatus in the Neotropical region harbors 25 helminth taxa, with monogeneans being the most commonly reported parasites. Brazil has the highest number of reports on parasitic genera.
