The natural cycle of nitrogen involves several biological and non-biological process
including: mineralization, nitrification, denitrification, nitrogen fixation, microbial and plant …

Anthropogenic increases in nitrogen (N) and phosphorus (P) concentrations can strongly
influence the structure and function of ecosystems. Even though lotic ecosystems receive …

Climate models predict widespread shifts in precipitation patterns and increases in the
frequency of extreme events such as droughts, but consequences for key processes in …

Invertebrate secondary production, or the formation of invertebrate biomass through time,
has been estimated in many freshwater benthic habitats. It has been a major research theme …

Headwater streams dominate natural landscapes and provide essential functions for
downstream waters. However, because of minimal legal protection, they often are piped or …

The quality and amount of productivity plays a central role in determining community
structure and biogeochemical dynamics in ecosystems. Humans have altered river …

Global climate change scenarios predict more frequent and extended droughts, especially in
the mid-latitudes. For many stream insects, these increasing periods of drought are likely to …

Mediterranean streams are characterised by seasonal droughts, the frequency and intensity
of which vary spatially and are expected to increase with global change. We studied the …

This study quantified patterns of macroinvertebrate secondary production and stored benthic
organic matter along a gradient of pollution and habitat channelisation over a 3‐km reach of …

We measured responses in macroinvertebrate secondary production after large wood
additions to three forested headwater streams in the Upper Peninsula of Michigan. These …
