Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components

Freshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

Evolution of the Cdk4/6–Cdkn2 system in invertebrates

Genes to Cells, Volume 29, Issue 11, Page 1037-1051, November 2024.
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

Infectivity of Chordodes nobilii larvae (Gordiida: Nematomorpha).

Revista de biologia tropical, 2017
Los gordiidos son representantes dulceacuícolas del Phylum parásito Nematomorpha que actúan como un enlace entre ecosistemas acuáticos y terrestres. En años recientes, diferentes estudios ecotoxicológicos se han desarrollado con una especie sudamericana de gordiido, C. nobilii, que ha demostrado la capacidad de este grupo de actuar como bioindicador de

Optimizing eDNA Replication for Standardized Application in Lotic Systems in Aotearoa, New Zealand

Environmental DNA, Volume 6, Issue 5, September–October 2024.
The objective of this study was to optimize eDNA sample replication for the consistent characterization of freshwater fish and aquatic macroinvertebrate communities in flowing New Zealand waters, and ultimately, to inform the development of robust national monitoring standards. Results indicated that six replicates were needed to consistently detect 89.

Symbiotic species diversity can explain invasion success and host–parasite system stability: The case of gammarid hosts

Ecosphere, Volume 15, Issue 7, July 2024.
Abstract A major current challenge related to invasions is the absence of a comprehensive theoretical basis for preventing the introduction of alien species and controlling their populations. By using a macroecological framework, we aim to examine patterns of symbiotic species diversity across native and invasive hosts to understand the mechanisms ...

Studies on the biology of the hairworms (Gordioidea, Nematomorpha)

Japanese Journal of Water Treatment Biology, 1991
In mid-Autumn 1983, the outbreak for the hairworm to be discharged through a tap with drinking water occured within a certain district of Kanagawa prefecture in Japan.After microscopic examination this worm was recognized as a kind of parasite belonging to Gordioidea, Nematomorpha.The specific characters of this worm were as follows.1) This worm ...

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.
