Accessing marine protists from the anoxic Cariaco Basin [PDF]
The ISME Journal, 2011 The earliest microbial cells evolved in an anoxic ocean (Martin and Muller, 1998), and many argue that the earliest Eukarya arose in the absence of oxygen as well. The microbe-mediated biogeochemical processes taking place below oxic/anoxic interfaces are of undeniable importance and interest, and the Cariaco Basin off the coast of Venezuela is a ...

Coexisting protist-bacterial community accelerates protein transformation in microcosm experiments
Frontiers in Marine Science, 2014 Proteins constitute the major portion of labile substances in the marine environment and are an important source of organic matter supporting marine ecosystems.

Mixotrophic Activity and Diversity of Antarctic Marine Protists in Austral Summer
Frontiers in Marine Science, 2018 Identifying putative mixotrophic protist species in the environment is important for understanding their behavior, with the recovery of these species in culture essential for determining the triggers of feeding, grazing rates and overall impact on ...

Spatial distribution of protists in the presence of macroaggregates in a marine system [PDF]
FEMS Microbiology Ecology, 2000 The spatial distribution of marine protistan communities in the presence of organic macroaggregates, formed from natural seawater, was studied in several microcosm experiments. The presence of macroaggregates had two main effects. First, the size of the communities of bacteria, flagellates and ciliates increased, as these communities were three orders ...

Biology, 2023 Heterotrophic protists are key components of marine ecosystems. They act as controllers of bacterial and microphytobenthos production and contribute significantly to the carbon flux to higher trophic levels.

Biotechnological alternatives for omega-3 polyunsaturated fatty acids production
Grasas y Aceites, 2006 Fish oils are the main sources of omega-3 (ω3) polyunsaturated acids (PUFA) such as eicosapentaenoic (C20:5ω3) and docosahexaenoic (C22:6ω3) acids. World demand for ω3 PUFA shows an increasing trend mainly due to the growth of the aquaculture industry ...

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance
Business Strategy and the Environment, EarlyView.ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

The eukaryome of modern microbialites reveals distinct colonization across aquatic ecosystems
npj Biofilms and MicrobiomesProtists are less studied for their role and diversity in ecosystems. Notably, protists have played and still play an important role in microbialites. Microbialites, or lithified microbial mats, represent the oldest evidence of fossil biofilms (~3.5 Gyr).

Two canonically aerobic foraminifera express distinct peroxisomal and mitochondrial metabolisms
Frontiers in Marine Science, 2022 Certain benthic foraminifera thrive in marine sediments with low or undetectable oxygen. Potential survival avenues used by these supposedly aerobic protists include fermentation and anaerobic respiration, although details on their adaptive mechanisms ...
