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

Insect Conservation and Diversity, EarlyView.
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.

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

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.

Species traits may predict extinction risk of Azorean endemic arthropods

Insect Conservation and Diversity, EarlyView.
Ground‐dwelling endemic arthropods face a higher extinction risk due to habitat degradation and invasive plants. Canopy species may seem less threatened but still face extinction risks from habitat fragmentation. Body size and trophic group did not predict species threat levels.

Variation in Zn, C, and N isotope ratios in three stream insects

FACETS, 2016
Total Zn concentrations and Zn isotope ratios were measured, using multicollector inductively coupled plasma (ICP)-mass spectrometry (MS), in three species of aquatic insects collected from a stream in Peterborough, Ontario, Canada.

Resource use, niche width, and trophic position reveal diverse trophic structure in a tidal freshwater zone fish community

Journal of Fish Biology, EarlyView.
Abstract The tidal freshwater zone is an aquatic transition zone that links a river to its estuary and provides an important habitat used in the life cycle of resident and migratory fishes. Yet, information on the trophic structure of fishes in this habitat is scarce. To address this gap, we characterize the trophic structure of a fish community in the

Diversity and Community Structure of Stream Insects in a Minimally Disturbed Forested Watershed in Southern Illinois [PDF]

, 2018
The Lusk Creek Watershed, located in Pope County, IL, long has been rec- ognized as a high quality area of biological significance, but surveys of the stream macroinvertebrate fauna have been limited.

Active predators do not necessarily specialize in sedentary prey: A simulation model

Annals of the New York Academy of Sciences, EarlyView.
Active predators, which move to find food, are assumed to specialize in sedentary prey. This study used an individual‐based simulation to test whether this assumption holds. The results show that active predators do not always specialize in sedentary prey; instead, prey choice greatly depends on prey spatial pattern and competition with ambush ...

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.

Do freshwater insect assemblages in exotic plantations resemble those from native forest? Evidence from environmental DNA

Restoration Ecology, EarlyView.
Widespread deforestation has impacted biodiversity patterns globally, but the potential for forest plantations to restore biodiversity remains unclear. Here we used environmental DNA (eDNA) analysis to compare freshwater insect assemblages between native and exotic forests in New Zealand, a region that has experienced heavy deforestation over recent ...
