Investigating the Effects of Flow Regulation Combining Stream Geomorphology With Macroinvertebrate Ecology: A Case Study in the Orobic Alps (Italy)

open access: yesEcohydrology, Volume 18, Issue 5, July‐August 2025.
ABSTRACT Mountain streams exhibit hydrogeomorphological heterogeneity, which is further intensified by the presence of hydraulic infrastructure. Despite extensive research on the influence of hydrological conditions and flow regulation on ecology, there is a notable absence of holistic studies investigating stream dynamics from both geomorphologic and ...

Effects of Dry‐Phase Frequency and Duration on Macroinvertebrate Assemblages in an Alpine Stream

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Although temporary streams are a common feature of fluvial networks, the prevalence of flow intermittency of perennial streams, especially in alpine landscapes, has increased with climate change. The fluvial network of the alpine Val Roseg catchment in eastern Switzerland experiences ca. 80% surface flow contraction over an annual cycle.

Hybridization in Phlebotominae (Diptera: Psychodidae): A mini-review

open access: yesInfection, Genetics and Evolution, 2020
Taxonomy based only on morphology, although extremely important for the classification of sandflies, has been shown to be insufficient for the delimitation of some taxa. Thus, integrative taxonomy could play a fundamental role in clarifying these and other taxonomic issues, since data from different areas are used to aggregate greater reliability in ...
