Summary: The impact of human activities on species richness is debated, with studies suggesting both negative and positive effects. The response of species richness to human pressure varies between regions and can be classified into different trajectories. Moderate human pressure may lead to an increase in species richness, but above a certain threshold, it results in a steep decline. Anthropophilic and non-native species may continue to increase even at high pressure levels.

Summary: The study evaluated the relationships between fish abundance, functional traits, and environmental conditions in a tropical Brazilian river under different levels of anthropogenic impacts. It found that high levels of human activities, grass-dominated riparian areas, and small-sized fish with internal fertilization were strongly associated. In contrast, less altered areas had tree-lined riparian zones, medium to large-sized fish with external fertilization, and diverse functional traits.

Summary: This study conducted a meta-analysis on 40 predatory species in 39 cities globally to investigate the effects of urbanization on predator trophic ecology. The results showed that predators in cities had comparable dietary richness, evenness, and nitrogen ratios, but higher carbon isotopic ratios compared to non-urban areas. The study also found that the human footprint index could not explain the variation in effect sizes.

Summary: The relationship between phylogenetic diversity and functional diversity varies across environmental gradients such as latitude and is influenced by ecological phenomena such as migration. Therefore, caution should be exercised when using phylogenetic diversity as a proxy for functional diversity, and empirical observations should be evaluated against biogeographically constrained and ecologically informed null models.

Summary: The natural ecosystem of the Hula Valley in Israel, including the old lake Hula, swamps, and cultivated land, was disrupted by drainage, resulting in a decline in biodiversity and negative effects on the water quality of Lake Kinneret downstream. After forty years, a reclamation project was implemented, leading to an improvement in hydrological conditions and agricultural development. Comparing the plant, bird, and fish inventories before and after drainage and reclamation, it was found that there was an enhancement in species richness and biodiversity. However, the long-term sustainability of the integration of agriculture and nature under the newly created conditions that enhanced biodiversity requires a risk assessment.

Summary: A review of literature and analysis of over 19,000 terrestrial protected areas worldwide found that the differences between strictly protected areas and areas where multiple human uses are permitted are often small and not statistically significant. While the effectiveness of protected areas varies globally, factors beyond their assigned IUCN category are likely influencing this pattern.

Summary: Understanding the response of biological communities to anthropogenic eutrophication is crucial for biodiversity conservation. This study combines paleolimnology and network science to propose a heterogeneity index (H) for measuring community successions. The results show that different degrees of eutrophication have varying effects on diatom communities, and there are discrepancies between different indices.

Summary: The Belt and Road (B&R) Initiative is closely aligned with the UN's Sustainable Development Goals by 2030 and could have a significant global impact. However, research and data accumulation on sustainable development in relation to B&R are currently inadequate. A comprehensive evaluation method called the Consumption-Pressure-Output-Efficiency method has been constructed based on the ultimate goal of sustainable development. A database with five datasets, including ecological consumption, planetary pressures, human well-being outputs, ecological well-being output efficiency, and related data, has been provided to facilitate further research on sustainable development under planetary pressures and others of B&R.

Summary: The study found that fish reproductive activity occurred both upstream of the Jirau Dam and within the Santo Antonio Reservoir. Some ichthyoplankton crossed the Santo Antonio Dam downstream, but at least some of their larval development stages disappeared along the reservoir. A critical section was identified in the last 10 km of the reservoir, possibly due to the drifting characteristics or mortality rates.

Summary: This study examines the impacts of dam construction on fish assemblages in tropical freshwater ecosystems. Rarely available data obtained before and after damming were used to assess the effects. The results showed negative trends in most response variables, with temporal and spatial variation playing a larger role in explaining the variation. Therefore, preserving upstream tributaries and natural environmental variation may help mitigate the impacts of damming on tropical ecosystems.

Summary: Flow regulation through dams increases water and energy security for society but also threatens the natural equilibrium of river basins, leaving ecosystems and communities more vulnerable. To guide the design of environmental flows and support improved ecosystem restoration, a methodology framework is proposed that builds an ensemble of flow regime options based on the naturalized flow regime range variability and quantifies the ecosystem response of each option in terms of migratory fish abundance with an artificial neural network model.

Summary: This study assessed the invasion process of non-native fish species in the upper Parana River floodplain from 1986 to 2018. It aimed to answer three questions: (1) whether non-native species abundance differs between lakes and rivers; (2) whether the probability of occurrence of non-native species differs between lakes and rivers over time, and (3) whether the probability of occurrence is explained by functional traits, phylogenetic relationships, or native range. The analysis showed that species abundance was higher in lakes, while the probability of occurrence was higher in rivers. Range size, functional traits, and habitat use dimensions positively influenced the probability of occurrence of non-native species. The most important functional traits included offspring investment, egg size and fertilization type, defense, and shape factor.

Summary: Extreme climate events and damming of rivers can intensify the impacts of droughts and floods on aquatic biota. This study investigates how a prolonged drought affects the similarity of aquatic metacommunities compared to a period with extreme flood events. The results suggest that while environmental variability decreases during drought, the homogenization of biota depends on the component of beta diversity considered. The findings highlight the importance of natural flood events for maintaining environmental variability and ecosystem functioning in floodplains.

Summary: River network rearrangements have significant effects on species dispersal and lineage diversification, with major landscape evolution events associated with abrupt shifts in net diversification rates. The Western Amazonia region in South America, with its high diversification rates and extensive biotic interchange, has played a crucial role in the assembly and diversification of fish faunas.

Summary: The introduction of non-native species and resulting biological invasions are prominent features of the Anthropocene Epoch. Some initiatives have emphasized the value and protection of invasive populations, but in the context of megadiverse tropical countries, the protection of highly invasive fishes, such as the peacock basses in Brazil, has raised concerns. Legal instruments have been proposed to restrict fishing and other activities to favor the recruitment, growth, colonization, and spread of these invasive species, but they pose significant risks of environmental degradation, biodiversity loss, and social conflicts.

Summary: The effects of river network rearrangements on species dispersal and lineage diversification are poorly understood. By studying South American freshwater fishes, it was found that major landscape evolution events led to abrupt shifts in net diversification rates. Western Amazonia, since the Mid-Miocene, has been an important source of species dispersing to other regions. The study supports the hypothesis that landscape dynamics strongly affected the assembly and diversification of basin-wide fish faunas.

Summary: This study evaluated the abundance of Salminus brasiliensis populations in the upper Parana River floodplain. Despite an overall decrease in abundance, less impacted sites had higher abundances and slower decline in probability of occurrence. These sites also showed improved fish condition over time. Protected areas in the upper Parana River played a mitigating role by slowing down population decline and serving as a source for propagation to other areas.
