[1] Research at the intersection of hydrology and ecology is central to a future in which human and ecological needs for water are met. We briefly identify several compelling research questions at this intersection, then focus on a critical research area central to hydroecology: river and stream restoration. Challenges in this area include the development of science to evaluate the effectivenes...

Changes in biodiversity owing to vegetation degradation resulting from widespread urbanization demands serious attention. However, the connection between vegetation degradation and urbanization appears to be complex and nonlinear, and deserves a series of long-term observations. On the basis of the Normalized Difference Vegetation Index (NDVI) and the image’s digital number (DN) in nighttime st...

1. Suitability of the local habitat (‘habitat filtering’) and dispersal between stream reaches determines the composition of insect communities, and urban land use may affect both processes. While urban streams are often poor habitats for insects and dispersal between them is often hindered, conservation and restoration activities generally focus solely on the local (in-stream) environment. 2. ...

Urban streams can provide amenities to people living in cities, but those benefits are reduced when become degraded, potentially even causing harm (disease, toxic compounds, etc.). Governments and institutions invest resources improve the values services provided by urban streams; however, conception, development, implementation of such projects may not include meaningful involvement community ...

Urban greenspace has gained considerable attention during the last decades because of its relevance to wildlife conservation, human welfare, and climate change adaptation. Biodiversity loss ecosystem degradation worldwide require formation new concepts ecological restoration rehabilitation aimed at improving functions, services, biodiversity conservation in cities. Although relict sites natural...

Most urban greening interventions involve soil de-sealing and management to enhance fertility. Management typically requires translocating fertile topsoil the site, which comes at great environmental costs. We hypothesized that de-sealed soils would undergo an increase of their fertility without exogenous application. assessed experimental plots with topsoil, topsoil. Both treatments were veget...
