Ecology of Groundwater (Amphibitic) Stoneflies

, 2023
Over 50 years ago Paraperla frontalis larvae were shown to exist in a shallow floodplain aquifer of a gravel-bed river in western Montana and later they were documented throughout the main stems of the Flathead River system. Larvae are almost never found in surface waters until they emerge on the river shorelines.

On the Feeding Habits of \u3ci\u3ePhasganophora Capitata\u3c/i\u3e (Plecoptera: Perlidae) [PDF]

, 2017
Gut contents of 230 nymphs of Phasganophora Capitata (Pictet) from the Pigeon River, Otsego County, Michigan were analyzed in relation to season, current velocity, time of day, predator size and prey abundance. Diet changed seasonally, related in part to

Evolutionary implications of a deep‐time perspective on insect pollination

Biological Reviews, Volume 100, Issue 4, Page 1452-1466, August 2025.
ABSTRACT Plant pollination by insects represents one of the most transformative and iconic ecological relationships in the natural world. Despite tens of thousands of papers, as well as numerous books, on pollination biology published over the past 200 years, most studies focused on the fossil record of pollinating insects have only been published in ...

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

Freshwater 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.

Community structure, life histories and secondary production of stoneflies in two small mountain streams with different degree of forest cover

Journal of Limnology, 2015
Our study examines community structure and nymphal biology (life cycles and secondary production) of stoneflies in two adjacent mountain streams with different degree of forest cover in the Prosiečanka River Basin (Chočské Vrchy Mts., West Carpathians ...

Scientists' warning on the need for greater inclusion of dragonflies in global conservation

Insect Conservation and Diversity, Volume 18, Issue 4, Page 465-484, July 2025.
Stressors to dragonflies are multiple, and in many cases interactive. Specialist species are at risk, while generalists can benefit from some human activities. Dragonflies are sentinels for conservation, being promising surrogates for other taxa while also being appealing to citizen science initiatives.

At last, a Pennsylvanian stem-stonefly (Plecoptera) discovered

BMC Evolutionary Biology, 2011
Background Stem-relatives of many winged insect orders have been identified among Pennsylvanian fossils (Carboniferous Period). Owing to their presumed 'basal' position in insect phylogeny, stoneflies were expected to occur at this period.

Life History Aspects of \u3ci\u3eAnthopotamus Verticis\u3c/i\u3e (Ephemeroptera: Potamanthidae) [PDF]

, 2017
The study of the larval development and life cycle of a population of the mayfly Anthopotamus verticis from the Tippecanoe River, Indiana was based on monthly and weekly sampling in 1990 and 1991.
