Summary: Different biological groups show biased responses to environmental stressors on different scales. Selecting bioindicators based on pressure characteristics is crucial for accurately assessing ecological quality. Macroinvertebrates and fish show distinct responses to environmental stressors, with their indices recommended for biomonitoring programs, especially in plain rivers.

Summary: In recent years, there has been growing concern about the decline in insect biodiversity, particularly among freshwater insects. To investigate the impact of climate change on freshwater insects, researchers conducted a study covering Central Europe from 1990 to 2018, analyzing shifts in insect abundance and diversity in relation to temperature and precipitation. The study found increases in both richness and abundance of freshwater insects, which were influenced by changes in summer and winter temperatures and precipitation. While this is a positive sign, the overall situation for freshwater invertebrates remains critical.

Summary: Investigating the impact of stream intermittency on the assimilation of aquatic prey by alpine riparian predators, it was found that alpine hunting spiders primarily consume terrestrial prey, with potentially higher contributions from aquatic prey during summer. This indicates opportunistic feeding behavior by these predators.

Summary: This study investigates the drying preferences of macroinvertebrates in intermittent rivers and ephemeral streams (IRES) and their potential as biomonitoring indicators. The research identifies certain macroinvertebrate groups with drying-resistant niches that can serve as potential indicators in IRES. However, functional traits have limited ability to predict drying specialization. The density, relative abundance, and richness of drying-resistant taxa are less affected by drying intensity compared to drying-sensitive taxa.

Summary: River and stream ecosystems in cities play a crucial role in maintaining biodiversity and providing ecosystem services to urban populations. However, the impacts of urbanization on biodiversity and ecosystem services are not well understood. This study aims to investigate the relationships between aquatic biodiversity, urbanization, and ecosystem services provided by urban streams.

Summary: The study revealed that agriculture-dominated karst areas had significant negative impacts on stream habitats and biota, with over half of the sites showing degradation. Wide riparian buffers and avoidance of groundwater influence have allowed for some recovery in certain stream reaches, but more buffers and soil conservation practices are needed to protect additional stream segments and biota. New stream buffer laws have resulted in establishment of vegetated buffers at all study sites, potentially leading to improved habitat and biotic communities in the future.

Summary: This study assessed the effects of land use on the benthic invertebrate assemblages of streams in the main Argentine agricultural region. The results showed that streams surrounded by croplands had higher nutrient concentrations, pesticide levels, and different macroinvertebrate assemblages compared to streams surrounded by pasture or reserve.

Summary: Riparian buffers along streams can intercept eroding soils, contaminants, and nutrients, improving stream habitats and increasing the health of aquatic communities. A survey conducted in a Minnesota stream showed that the implementation of a state-mandated buffer law resulted in improved stream habitats and fish and benthic invertebrate communities. However, the improvement in biotic community metrics was not significant, indicating that more time may be needed for the biotic communities to adapt to the changed habitat conditions.

Summary: Riparian zones play a crucial role in freshwater ecosystem processes and biodiversity conservation. A study on freshwater invertebrates in Neotropical savanna headwater streams revealed that certain biological traits are significantly impacted by anthropogenic stressors, such as increased disturbance, lower substrate heterogeneity, and higher water temperature. These findings provide valuable insights for environmental management and monitoring efforts in tropical savanna headwater ecosystems globally.

Summary: This study used variance partition techniques to assess the performance of different benthic invertebrate metrics in detecting agricultural land-use effects in a rainforest watershed in SE Brazil. The results showed that traditional bioindicator metrics were more responsive to environmental variation associated with agriculture compared to taxa abundances and functional attributes. These findings have important implications for the development of macroinvertebrate-based biomonitoring protocols.

Summary: This study aimed to investigate the impact of land use and land cover on aquatic insect assemblages in the Amazon region, identifying sensitive taxa to environmental gradients. The results showed that as forests are converted to pasture, sensitive taxa to pasture experienced a decrease in abundance and frequency of occurrence, indicating their potential as indicators of stream conservation.

Summary: This study provides the first estimation of aquatic subsidies provided by flying insects that emerge from streams and land on cropland. The results suggest that the amount of emerging and dispersing aquatic insects in intensive agricultural landscapes may be higher than previously described in natural settings.

Summary: Urbanization poses a serious threat to stream ecosystems worldwide, and understanding its effects on stream organisms is crucial for mitigating urban degradation. This study investigated the general effects of urbanization in a moderately urbanized landscape and examined the relationship between local environmental variables and macroinvertebrate assemblages. The results showed that urban sites had degraded habitat conditions, with negative impacts on macroinvertebrate richness and diversity. Concrete cover was identified as a key factor contributing to reduced richness and diversity. The study also found that the impact of environmental variables varied between natural and degraded conditions, indicating the need for diverse mitigation strategies.

Summary: The impact of different land uses on the diversity of aquatic insects in the Amazon forests was studied. It was found that while contiguous and fragmented forest streams had similar environmental conditions, they differed in terms of insect diversity. The highest alpha-diversity was observed in contiguous forest streams, while streams surrounded by livestock farming and primary oil palm plantations had higher beta-diversity. This has important implications for the protection and restoration of forest fragments to prevent the degradation of Amazonian streams.

Summary: Insular populations of mammals undergo morphological changes compared to mainland populations, which provide insights into the evolutionary effects of predation and competition. Selection favors energetically efficient body plans in insular mammals, even if it means reducing anti-predator defenses. This study examines the effects of insularity on brain size in two conspecific populations and finds that insular deer have significantly reduced brain mass compared to mainland conspecifics, indicating a relatively quick selection for reduced brain size after isolation.
