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

Environmental 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.

KF‐metaweb: A trophic metaweb of freshwater ecosystems of South Korea

Global Ecology and Biogeography, Volume 33, Issue 7, July 2024.
Abstract Motivation The metaweb is a dictionary of nodes and their potential interactions developed for a particular region, focusing on a particular type of ecosystem. Based on the local biodiversity information at different spatial and temporal scales, the regional metaweb can be easily decomposed into local webs.

Palaeoscolecids from the Ludlow Series of Leintwardine, Herefordshire (UK): the latest occurrence of palaeoscolecids in the fossil record

Papers in Palaeontology, Volume 10, Issue 3, May/June 2024.
Abstract The documentation of cuticular micro‐ornament is vital for the taxonomic assignment of palaeoscolecids: vermiform lower Palaeozoic ecdysozoans interpreted as stem‐group priapulans or early diverging panarthropods. This is due to the absence of the character‐rich proboscis and tail hooks in palaeoscolecid material not from Burgess Shale‐type ...

Tales from the crypt: a parasitoid manipulates the behaviour of its parasite host [PDF]

, 2017
There are many examples of apparent manipulation of host phenotype by parasites, yet few examples of hypermanipulation—where a phenotype-manipulating parasite is itself manipulated by a parasite. Moreover, few studies confirm manipulation is occurring by

Facilitating the recovery of insect communities in restored streams by increasing oviposition habitat

Ecological Applications, Volume 34, Issue 2, March 2024.
Abstract Recruitment limitation is known to influence species abundances and distributions. Recognition of how and why it occurs both in natural and in designed environments could improve restoration. Aquatic insects, for instance, rarely reestablish in restored streams to levels comparable to reference streams even years after restoration.
