Life Cycles of \u3ci\u3eLeuctra Duplicata\u3c/i\u3e and \u3ci\u3eOstrocerca Prolongata\u3c/i\u3e in an Intermittent Streamlet in Quebec (Plecoptera: Leuctridae and Nemouridae) [PDF]

, 2017
Large populations of Ostrocerca prolongata and Leuctra duplicata developed in a small intermittent stream in the foothills of the Laurentian Highlands of Quebec. Both species were univoltine in 1974-1975.

Differences in Thermal Tolerance Between Two Thermally Isolated and Genetically Indistinct Populations of \u3ci\u3eParagnetina Media\u3c/i\u3e (Walker) (Plecoptera: Perlodidae) [PDF]

, 2018
The critical thermal maximum (CTM) of Paragnetina media (Walker) (Plecoptera: Perlodidae) was studied at two sites of the Big Sable River in northwestern Lower Michigan during summer 2013. The sites were separated by ~8 km and differed in temperature by ~

Spatiotemporal assessment of benthic macroinvertebrate communities in the Bermejo River Basin in the Ecuadorian Amazonia

Limnology and Oceanography Letters, EarlyView.
Abstract The Cofán communities rely on the Cofán Bermejo Ecological Reserve for their survival and cultural practices. Due to the rugged and inaccessible topography of the reserve in the Northern Ecuadorian Amazon region, limited biomonitoring and ecological characterization studies of the ecosystem health have been conducted.

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.

Stoneflies (Plecoptera) of Nevada [PDF]

Monographs of the Western North American Naturalist, 2017
Abstract. Stoneflies (Plecoptera) are a dominant group in running freshwaters. We report 104 stonefly species from Nevada. The fauna contains species with Sierra Nevada—Cascade range affinities, few of which penetrate far eastward, and Rocky Mountain species extending to western Nevada.

Rivers as Natural Capital Assets: A Quick Scoping Review to Assess the Evidence Linking River Asset Condition to Changes in the Flow of Ecosystem Services

River Research and Applications, EarlyView.
ABSTRACT River managers are beginning to adopt natural capital approaches in practice. However, while it is crucial for river management, the link between river asset condition and the flow of ecosystem services is poorly understood. In this study, we conducted a Quick Scoping Review (QSR) of the research into river asset condition and ecosystem ...

Impacts of Habitat Management on Larvae of the Damselfly Coenagrion mercuriale (Coenagrionidae, Odonata)—A Laboratory Study

River Research and Applications, EarlyView.
ABSTRACT Habitat management of small lotic waterbodies is essential to maintain flow and the quality of the habitats. For this purpose, aquatic plants are typically removed by authorities. This is done in a more or less disruptive manner, depending on the risk of interference with the bed.

Preserving Short‐Sward Natural Grasslands May Provide Suitable Foraging Habitat for a Climate‐Threatened Alpine Species Along Ski‐Pistes

Animal Conservation, EarlyView.
Investigating the ultimate factors that underpin the impacts of ski‐pistes on alpine species is crucial to identify concrete mitigation strategies. This is urgently needed given that winter sports are expanding in mountain ranges worldwide. We evaluated the impacts of ski‐pistes on the foraging behaviour of the white‐winged snowfinch, an iconic alpine ...
