Summary: This study in the Middle-lower Yangtze River Region in China found that human disturbance can lead to changes in isotopic niche space and overlap between introduced red swamp crayfish and native oriental river shrimp and freshwater snail, potentially increasing competition, especially in modified habitats. The exotic crayfish showed greater competitive superiority over the native species, with changes in niche width and overlap depending on habitat modification.

Summary: Controlling and planning the removal of invasive species is of great importance in natural resource management. By combining population dynamics models with optimization procedures, an effective allocation of resources can be achieved. In this study, we propose a parabolic optimal control model that incorporates external forces to improve the accuracy of the model. We also introduce a novel numerical procedure to reduce computational costs.

Summary: The stability of alpha-Monoboryl anions and their resonance form borata-alkene systems are discussed in this review, along with the synthetic approaches and properties of the C=B bond. The characterization by X-ray diffraction and NMR data provide evidence for the partial boron-carbon double bond character, while reactivity studies demonstrate the nucleophilic potential of the C=B bond in electrophilic trapping examples. Homologation protocols with diborylmethane offer a facile method for introducing C(sp(3))-B bonds for subsequent transformations into functionalized products.

Summary: A large reservoir of nitrate was found in the subsoil of an arroyo floodplain in the northern Chihuahuan Desert in central New Mexico, with concentrations over twice as high as any previously measured arid region. Plant communities are larger and more abundant in the floodplain compared to the adjacent desert, though subsoil nitrate is apparently not utilized. The results have major implications for land-use planning in arroyo and ephemeral stream floodplains as well as arid region soil biogeochemistry.

Summary: This study evaluated the impact of exotic Populus species on the development of softwood riparian forests, finding that the reintroduction of native Populus nigra and restoration of natural river dynamics led to a shift in reproductive success in favor of the native species. Despite significant gene flow from exotic poplars in European floodplains, restoration programs of native P. nigra can effectively outcompete exotic gene flows and reduce the impact of exotic Populus species on softwood riparian forest development.

Summary: This study investigated the phylogenetic and biogeographical history of Hydrocharis and Limnobium through sequencing and assembling plastomes. The results showed that the African species H. chevalieri is sister to the remaining species, and L. laevigatum is nested within Hydrocharis. Hydrocharis and Limnobium diverged during the Miocene and likely originated in Europe and Central Africa. Based on the phylogenetic results and morphological similarity, it is suggested to treat Limnobium as a synonym of Hydrocharis.

Summary: Water-level oscillations play a significant role in shaping the community structure and diversity of chironomid larvae in tropical lakes. Environmental factors have a greater impact on chironomid composition during low-water-level periods compared to high-water-level periods. Extreme low- and high-water-level periods in floodplain systems may become more frequent and intense in the future, affecting the richness, density, and temporal beta-diversity of chironomids.

Summary: This study investigated the distribution of L. fortunei larval stages in floodplain environments and identified local abiotic filters that affect the density of each larval stage. The results showed that L. fortunei population pyramid is expanding in these environments, with the youngest larval stages accounting for the majority of the density. Abiotic factors such as turbidity, water level, and suspended inorganic matter directly decreased the density of the youngest larval stages, while temperature and pH directly increased the density of older larval stages. Water level indirectly affected the density of the youngest larval stages through its effects on turbidity and suspended inorganic matter.

Summary: Invasive species show greater resilience to drought but are more negatively affected by interspecific competition compared to native species. The high dominance of invasive species in aquatic ecosystems can be explained by their ability to recover from drought disturbances, while the presence of native species acts as a biotic resistance mechanism.

Summary: This study examines the effects of nutrient loading on shallow lakes, and how regime shifts from clear water to turbid or shaded states affect biodiversity and ecosystem functioning. The results show that functional diversity is the best predictor of ecosystem multifunctionality, and that regime shifts towards turbid or shaded states negatively impact taxonomic diversity and functional diversity of fish and zooplankton, leading to decreased multifunctionality.

Summary: This study estimates the rate of increase and doubling times of new records of 178 invasive alien species (IAS) using a global dataset. It finds that the number of IAS records has exponentially increased with a mean doubling time of around 14 years across the Earth. The records of IAS increased faster in non-native continents, suggesting an exponential expansion of their range size. Each continent has a taxonomic group with a particular increase in IAS records. The study highlights the need for more effective global efforts to control invasions.

Summary: Many studies have shown that biodiversity plays a crucial role in maintaining the productivity and functionality of ecosystems. In this study, the researchers investigated the association between species richness, functional diversity, and ecosystem multifunctionality in 72 lakes across four wetlands in Brazil. They found that higher species richness and functional diversity were positively correlated with ecosystem multifunctionality. However, human activities negatively impacted the diversity of aquatic organisms, leading to a decrease in wetland multifunctionality.
