Two new species of the Rhyacophila nigrocephala species group from China (Insecta, Trichoptera, Rhyacophilidae)

European Journal of Taxonomy, 2017
Two new species of the Rhyacophila nigrocephala species group, R. voluta sp. nov. and R. linguiformis sp. nov., are described, diagnosed and illustrated. Rhyacophila voluta sp. nov. is similar to R.

A framework to identify dispersal and establishment constraints in restoration: Freshwater macroinvertebrates as an illustrative example

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
In restoration practice, initial state assessment is often insufficient to identify specific limiting factors, with practitioners resorting to off‐the‐shelf restoration methods which may not be appropriate. In the case of lotic invertebrate communities, the tools to comprehensively assess communities do exist; we need to improve understanding and ...

Strategic conservation prioritization through creating and updating the regional species of greatest conservation need list in the northeastern United States

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
Biodiversity is declining globally, underscoring the need for conservation strategies informed by regional expertise. In the northeastern United States, 14 state wildlife agencies and taxonomic experts developed the Regional Species of Greatest Conservation Need (RSGCN) list, revealing that global and national datasets captured only ~55% of regionally ...

Environmental heterogeneity at different scales: key factors affecting caddisfly larvae assemblages in standing waters within a lowland river catchment

Journal of Limnology, 2016
We examined the importance of environmental parameters at different spatial scales influencing the occurrence of caddisfly larvae at different levels of their organization (species, faunistic metrics and functional groups) in lentic floodplain waters, in

The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Drought and Human Pressures Contribute to Persistent Changes in Freshwater Invertebrate Communities

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Freshwater ecosystems are threatened by increasing climate extremes including drought, which interacts with human pressures to drive biodiversity loss across spatial scales. River communities are considered resilient to droughts, but this characterization is based on short‐term, small‐scale studies. Moreover, drought resilience is increasingly

Caddisfly Species Differ in Whether Intraspecific Variation in Wing Size Affects Dispersal in a Natural Landscape

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Species' metapopulation dynamics and connectivity can depend on whether dispersers comprise a random or phenotype‐dependent subset of the population. However, whether and which phenotypic traits characterise dispersing individuals is unknown for many invertebrates.

Swarming caddisflies in the mid-cretaceous

National Science Review
ABSTRACT Swarming, as a special form of mating aggregation, is most noteworthy in insects of the orders Ephemeroptera, Diptera, and Trichoptera. Swarming in extant trichopterans is well understood in terms of sex composition, specific mating behaviors, and functional morphological specializations of adults, but an exploration of the ...

Leaf litter input and electrical conductivity may change density of Phylloicus sp. (Trichoptera: Calamoceratidae) in a Brazilian savannah stream

Acta Limnologica Brasiliensia
Aim Shredders are generally not abundant in tropical streams, and there is considerable evidence suggesting that the food supply drives this pattern in headwaters.
