A Scavenging Behavior of Cyclammina cancellata (Foraminifera, Rhizaria) on a Crustacean Carcass: Amino Acid Nitrogen Isotope and Microbiome Analyses

Marine Ecology, Volume 46, Issue 3, May/June 2025.
ABSTRACT Cyclammina cancellata is a common benthic foraminifer found at bathyal depths across the world's oceans. Despite its important role in deep‐sea food webs and biogeochemical cycles, the feeding habits of this species remain poorly understood. In this study, we document an aggregation of C.

The food and feeding habits of the anchoveta, Cetengraulis mysticetus, in the Gulf of Panama [PDF]

, 1963
ENGLISH:The gill rakers of both juvenile and adult anchovetas are long and numerous, with many fine processes which make a very efficient straining apparatus. The stomach is modified into a gizzard.

Geomorphic consequences of freshwater discharge and microbial mats in a macrotidal environment: The case of the beach of Dannes (northern France)

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This transdisciplinary study analyses the geomorphic consequences of microbial mats associated with freshwater outflows in a macrotidal environment. Microorganisms were identified using the DNA metabarcoding approach. SEM analysis of quartz collected from the beach surface provided data on the marine and aeolian forces, as well as biological processes ...

Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes

Journal of Eukaryotic Microbiology, Volume 66, Issue 1, Page 4-119, January/February 2019., 2019
Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.

18S rRNA Metagenomic Analysis of Nodular Gill Disease in Swiss Rainbow Trout (Oncorhynchus mykiss)

Journal of Fish Diseases, Volume 48, Issue 3, March 2025.
ABSTRACT Nodular gill disease (NGD) is a serious proliferative gill condition that affects farmed salmonids, particularly in Europe. While the cause of NGD remains unknown (and maybe multifactorial), various amoebae are often isolated from the gills of affected fish and can in some cases be seen associated with lesions by histopathology.

Biogeographical Distribution of River Microbial Communities in Atlantic Catchments

Environmental Microbiology Reports, Volume 17, Issue 1, February 2025.
We discovered different factors affecting river microbial communities (RMC) diversity and composition across Atlantic catchments in Europe. Prokaryote diversity was mainly influenced by topography and geology, while eukaryotic groups were driven by land use and cover.

Geochemical and microbiological variability of aerobic and anaerobic sediments along a bifurcated sulphate‐saturated brine spring in western Canada

The Depositional Record, Volume 10, Issue 5, Page 637-669, November 2024.
A tufa mound developed in north‐east Alberta is characterised by an unusual emplacement of a gypsum caprock. This two‐tiered architecture resulted from the bicarbonate‐saturated groundwater flow along Upper Devonian limestone being redirected deeper and encountering the halite–anhydrite dissolution trend within the underlying Prairie Evaporite ...
