Effect of environmental factors on survival and population growth of ciliated parasite,Mesanophryssp. (Ciliophora: Scuticociliatia) infectingPortunus trituberculatus

Parasitology, 2020
AbstractMesanophryssp. is a newly identified parasitic ciliate infecting farmed swimming crab. To demonstrate the correlation between parasite development and environmental conditions, this study aimed to investigate the effect of temperature, salinity, pH and frequency of passage of parasite on survival, growth and body size ofMesanophryssp.in vitro ...

Ciliaten (Protozoa, Ciliophora) des Reisfeldbodens [PDF]

, 2003
Reisfeldböden sind die Bodenökosysteme, die während der letzten Dekade am intensivsten studiert wurden. Dabei haben sich Reisfeldböden in den letzten Jahren als geeignetes Modellökosystem zur Untersuchung von mikrobiellen Populationen und ...

Seasonal growth and reproductive dynamics of Chondrus ocellatus in relation to shore height in the Korean intertidal zone

Phycological Research, EarlyView.
SUMMARY We examined the seasonal growth and reproduction of the carrageenophyte Chondrus ocellatus in Hakampo, Korea (July 2014–April 2015), to understand its adaptation to environmental variability across the intertidal zone. Three hypotheses were tested: (1) growth is greater at the lower shore with reduced stress; (2) gametophytes dominate at the ...

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]

, 2014
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...

Higher Trophic Status Leads to More Diverse and Divergent Microeukaryote Communities Over Time in Urban Lakes From the Greater Paris (France)

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microeukaryote dynamics across a eutrophication gradient in Greater Paris region lakes showed richness peaking at intermediate trophic levels and communities becoming more modular, variable, and less connected with higher trophic status compared to oligo‐to‐mesotrophic lakes.

Description of a new actinosporean type from South African freshwater [PDF]

, 2004
The 1st report on actinospores described these organisms as parasites related to myxosporeans. For a long time this group of parasites was believed to represent an independent taxonomic entity.

Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments

Environmental DNA, Volume 8, Issue 3, May–June 2026.
We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...

Comparative Analysis of Gut Eukaryotic Communities in Three Laboratory‐Reared Cockroach Species Using Metabarcoding

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Cockroaches are known reservoirs for diverse bacterial microbiomes. However, comprehensive analyses of the eukaryotic communities within cockroaches remain limited. In this study, we selected three long‐term laboratory‐reared cockroach species (Blattella germanica, Periplaneta fuliginosa, and Periplaneta japonica) and performed metabarcoding ...

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.
