Assessing Regional Variation in the Relationships Between Local Stream Characteristics and Culvert Barrier Attributes Relative to Fish Passage

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Stream fragmentation is a leading threat to freshwater fish diversity and is often caused by the installation of impassable culverts at road–stream crossings. In the United States alone, millions of culverts contribute to this fragmentation. Therefore, estimating culvert barrier impact on aquatic organism passage and prioritizing barriers for ...

Evaluating Movements of Co‐Occurring Silver and Bighead Carp in a Small Missouri River Tributary

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis commonly inhabit small tributaries of mainstem rivers. However, dynamic environmental conditions within these systems may influence their movement patterns differently than in larger rivers, potentially leading to important implications regarding their range ...

Associating Local‐Scale Physical Habitat Assemblages With Reach‐Scale Stream Hydrogeomorphological Types in Mountain Headwater Catchments

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...

Avoiding the ‘One‐Size‐Fits‐All’ Trap in Policy‐Based Monitoring

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Policy‐based monitoring programmes often fail to yield the information required to assess and improve policies and plans. A dominant cause of this problem is the ‘one‐size‐fits‐all’ (OSFA) trap—a failure to recognise that several, complementary types of monitoring are required to support effective policy.
