Summary: Microeukaryotes and bacteria play important roles in aquaculture ecosystems. This study examined their co-occurrence relationships using high-throughput sequencing data. The networks showed dominant phyla of Chlorophyta and fungi in water and sediment, respectively. Most microeukaryotes and bacteria were classified as generalists and had symmetric connections. Some microeukaryotes had asymmetric connections in water. Four microeukaryotes and twelve uncultured bacteria were identified as potential keystone taxa. The microeukaryotic-bacterial bipartite network in sediment had more nestedness compared to water. Loss of microeukaryotes and generalists could lead to the collapse of positive co-occurrence relationships in both water and sediment. This study provides insights into the structure and function of microeukaryotic-bacterial networks in aquaculture ecosystems.

Summary: The quantities and ratios of nutrients play a role in the topological properties of algal co-occurrence networks, while climate and space also impact network topology. Nutrient supply was positively related to network size, and climatic and spatial variables had significant effects on network topology, depending on nutrient context.

Summary: Large branchiopods are crucial for temporary ponds' ecosystems and their disappearance in Tanzania due to human activities is a concern. In this study, we compared temporary ponds in protected areas with those in communal lands, and found that land-use types affect the structure of large branchiopod community. We found six large branchiopod species, including one new species, and identified the most abundant and widely occurring species. The variation in community structure was influenced by the presence of Nothobranchius killifish and orthophosphate concentration. Understanding the relationship between land-use types and large branchiopod communities can guide the management of temporary pond ecosystems.

Summary: This study assessed the importance of different riverine environments for the early development of fish larvae from different reproductive guilds. It found that long-distance migratory species are more sensitive to habitat loss compared to short-distance migratory species. Protecting tributaries is crucial for the reproduction of long-distance migratory species.

Summary: Metalliferous mine tailings ponds, extreme environments resembling early Earth conditions, have been found to have higher fungal diversity than previously thought. Saprotrophic fungi dominate these habitats. Fungal community assembly is primarily driven by stochastic processes, with soil nitrogen and phosphorus playing a role in the balance between stochastic and deterministic processes. Co-occurrence network analysis shows a highly modular structure, with main modules consisting of saprotrophic fungi and unknown functional guilds. Core fungal phylotypes, positively correlated with soil properties, play important roles in soil organic matter decomposition and nutrient cycling.

Summary: The invasion of Moso bamboo has significant effects on soil microbial communities and enzyme activities, leading to increased soil pH and organic carbon concentrations, decreased fungal gene abundances, and changes in co-occurrence networks. These results underscore the importance of sustainable forestry management to maintain fungal diversity and network complexity in the face of bamboo invasion.

Summary: The research in the Vistula Lagoon revealed that detritivorous Tubificinae and chironomid larvae have the highest density at the depth of 0-10 cm, with significant co-occurrence in the layers of 0-2 cm and 2-5 cm. Their interactions in sediment reworking show complementary roles, with Chironomus larvae affecting deeper layers and Oligochaeta affecting both deeper and surface layers, avoiding competitive exclusion and allowing for co-occurrence.

Summary: This study investigated the occurrence of organochlorine pesticides (OCPs) in inland freshwater aquaculture ponds (IFAPs) in China. The results showed significant variations in OCP levels in sediments between different regions, with crabs being the most contaminated species. DDTs were found to be the dominant contaminant in both sediments and crabs, with stable degradation products 4,4'-DDE and 4,4'-DDD co-occurring in these compartments. The study also suggested that fresh inputs of DDTs, lindane, and aldrin in multiple regions may be attributed to agricultural soil erosion, surface runoff, and local anthropogenic activities.

Summary: The study found that lizard species endemic to Mediterranean islands are mainly found on islands farther from the mainland, with higher levels of island connectivity showing more endemic species. Mainland species are more prevalent on larger islands. Additionally, endemic lizards tend to occupy niches that align with average environmental conditions, while mainland species are usually found in more peripheral environmental positions.

Summary: Disturbances, such as wildfires, are key drivers of biodiversity dynamics, impacting landscape structure and metacommunity networks. Communities show high resilience to disturbances, with recovery linked to dispersal abilities. However, increased disturbance regimes may threaten this resilience, with disturbance size and intensity playing crucial roles in determining community recovery rates.

Summary: The study revealed climate niche partitioning among lacertid lizards in south-western Europe, with overlapping in transitional zones where species maintain segregation through responses to vegetation cover. Phylogenetically related species tend to share large parts of their habitat niches, while the occurrence of independent evolutionary lineages contributes to regional species richness.

Summary: The Pacific Ocean, the largest in the world, contains diverse reptiles in remote archipelagos. This study found that there are spatial effects on species' dispersal ability, and this effect is more significant than the phylogenetic effect. The reproductive mode and body size also play a role in the dispersal capacity of island squamates.

Summary: This study evaluated the influence of climate on the distribution of the king cobra and predicted its future distribution. Through phylogenetic analysis, the researchers found that the current distribution of the species is strongly correlated with humid climate conditions. The study also suggests that the absence of the king cobra in Sri Lanka and Taiwan can be explained by the lack of suitable climatic corridors during the connection between these islands and the mainland.
