Summary: The United States Environmental Protection Agency and the Houlton Band of Maliseet Indians collaborated to build a stream temperature model for the Meduxnekeag Watershed, using a high-resolution hydrology dataset. The model predicted stream temperatures at different time periods, guiding riparian restoration projects to expand habitat for cold water fishes.

Summary: The study found a strong correlation between air temperature and stream temperature, with the intermittent tributary having a localized moderating effect on stream temperature. Riparian vegetation cover showed little impact on stream temperature along the entire riparian corridor.

Summary: Low-order streams and riparian wetlands play important roles in the drainage network of landscapes. However, there has been limited research on these ecosystems in Brazil. In Brazil, riparian wetlands cover at least 25% of the forested part of the Amazon basin and about 10% of the Cerrado region. Large-scale agriculture and cattle ranching pose significant threats to these wetlands.

Summary: Forests have both biochemical and biophysical effects on climate, and the biophysical effects of afforestation in arid regions have been less studied compared to other regions. In this study, the impacts of arid forests on surface temperature were characterized using eddy covariance flux measurements and the decomposed temperature metric (DTM) method. It was found that afforestation led to a cooling effect from March to September and a slight warming effect in other months, with evapotranspiration playing a dominant role in cooling surface temperature.

Summary: This study analyzed the impact of leaf identity and riparian cover on leaf decomposition in subtropical streams. The study found that the presence of riparian cover influenced the effect of different predictors on the decomposition process. Additionally, changes in leaf identity were found to have a significant impact on leaf decomposition.

Summary: The study revealed that woody riparian vegetation plays a significant role in reducing maximum water temperature, with shading helping to lower water temperature. Furthermore, the length, width, and canopy cover of riparian buffers also have varying effects on water temperature.

Summary: The study highlights the long-term impacts of forest disturbances on adjacent streams, particularly on specific populations such as Scopura montana. Clearcut logging exposes the stream surface to sunlight, leading to increased water temperature; while landslides result in higher streambed roughness.

Summary: The accurate detection and mapping of instream wood is important for sustainable forest management. This study developed and tested a novel framework to use Airborne Laser Scanning (ALS) data to automatically detect and map instream wood. The results showed that the method had moderate overall accuracy and could be used for fish habitat modeling and assessing management practices.

Summary: Livestock grazing in riparian areas has both positive and negative effects on vegetation. While reserving riparian areas can benefit native vegetation, livestock grazing can reduce exotic vegetation cover at the cost of native vegetation and ground condition. Quantitative monitoring and evaluation of cost-benefit trade-offs are essential for guiding reservation decisions.

Summary: Human activities such as forestry can have negative impacts on freshwater ecosystems that support juvenile salmon. Forestry activities alter water temperatures and the delivery of water and nutrients in streams, affecting the habitat and survival of juvenile salmon. This study examines the relationship between forestry and stream habitat in interior watersheds and finds that forest harvest is positively correlated with maximum summer stream temperature, while stream gradient explains most of the variation in physical habitat.

Summary: Understanding changes in salmonid populations and their habitat is crucial due to climate change and their importance as a keystone species. Airborne Laser Scanning (ALS) data can be used to assess the quality and quantity of salmonid habitat, as well as characterize detailed stream attributes. ALS data provides detailed Digital Elevation Models (DEMs) and can be utilized for sustainable forest management decision making and advanced salmonid habitat modeling.

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: Increasing iron concentrations in freshwaters across northern Europe have led to browning, affecting aquatic organisms and drinking water production. The contribution of different sources to stream iron concentrations is not well understood. This study investigated the role of riparian and mire soils in regulating iron patterns in a boreal stream network over 18 years. Results showed that riparian soils were major contributors to increasing freshwater iron concentrations, and drought events led to prolonged release of iron from organic soils, with potential long-term effects on stream iron concentrations.

Summary: The study revealed that forested riparian buffers are associated with greater shading, increased gravel content in stream substrates, and faster flow velocities. It also found that riparian vegetation types influence the structural and functional composition of stream invertebrate communities, with implications for stream health and cross-ecosystem connectivity.

Summary: Riparian zones play a crucial role in transforming and retaining nutrients and sediment. This study investigates the direct influence of precipitation on material retention and transport in these zones. The findings suggest that vegetated riparian zones have a high capacity for retaining nitrate.
