Environmental Quality and Aquatic Invertebrate Metrics Relationships at Patagonian Wetlands Subjected to Livestock Grazing Pressures [PDF]

open access: yes, 2015
Livestock grazing can compromise the biotic integrity and health of wetlands, especially in remotes areas like Patagonia, which provide habitat for several endemic terrestrial and aquatic species.

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Palaeoendemic invertebrates weakly reflect palaeoendemic plants across a 52‐year‐old fire boundary

open access: yesAustral Ecology, Volume 49, Issue 9, September 2024.
Palaeoendemic invertebrates are associated with palaeoendemic vascular plants more than could be expected by chance in alpine/subalpine ecosystems on either side of a 52‐year‐old fire boundary. However, some palaeoendemic invertebrates are generalists in their associations with plant species.

eDNA Is a Useful Environmental Monitoring Tool for Assessing Stream Ecological Health

open access: yesEnvironmental DNA, Volume 6, Issue 4, July–August 2024.
Ecosystem health assessments made by traditional biomonitoring techniques were compared to those made using eDNA at 53 sites throughout New Zealand. We found a high degree of correlation and convergence between biotic indices calculated from traditional biomonitoring techniques and from eDNA.

Long‐term environmental flows restore benthic invertebrate communities in a highly regulated river

open access: yesRestoration Ecology, Volume 32, Issue 5, July 2024.
The construction of dams and other in‐stream structures for human use has altered river ecosystems worldwide. Dams degrade rivers, and environmental flow releases aim to mitigate flow alterations and restore rivers downstream of dams by returning elements of the pre‐regulation flow regime, resulting in an ecosystem that resembles a more natural state ...

The effects caused by the replacement of native riparian forest with Eucalyptus sp. on the benthic macro-invertebrate community. [PDF]

open access: yes, 2017
The replacement of native riparian forests with exotic plants, especially Eucalyptus sp. can cause changes in ecological processes of small orders rivers. The leaves of Eucalyptus sp.
