ABSTRACT Invasive species such as grass carp (Ctenopharyngodon idella) pose substantial ecological threats to North American freshwater ecosystems. Understanding their early life stage behavior is critical for management efforts. From spawning to hatching, invasive carp eggs must remain suspended in the water column while drifting downstream for the ...

ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

Macroinvertebrates and water quality: a teaching guide [PDF]
Streams support a diverse community of plants and animals on or in the stream bed. These organisms comprise the benthos. Among the benthos are worms, molluscs, crustaceans, and larval insects.

ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...
