Geochemical proxies—such as the isotopic compositions and abundances of redox-sensitive metals, organic biomarkers, and sedimentological indicators—can be used qualitatively and quantitatively to reconstruct marine redox landscapes through Earth

We studied the population dynamics and parasite load of the foraminifer Cibicides antarcticus on its host the Antarctic scallop Adamussium colbecki from three localities differing by sea ice cover within western McMurdo Sound, Ross Sea, Antarctica: E

DIVERSITY, BIOGEOGRAPHY, BODY SIZE AND FOSSIL RECORD OF PARASITIC AND SUSPECTED PARASITIC FORAMINIFERA: A REVIEW

Autor: Sally E. Walker, Samuel S. Bowser, Leanne G. Hancock

Publikováno v: The Journal of Foraminiferal Research. 47:34-55

We review the ecology and fossil record of parasitic and suspected parasitic foraminifera. Nine species of foraminifera are known to be parasitic, obtaining nutrients from their host, and 13 are suspected parasites that require taxonomic and ecologic

Methane cold seep systems typically exhibit extensive buildups of authigenic carbonate minerals, resulting from local increases in alkalinity driven by methane oxidation. Here, we demonstrate that modern seep authigenic carbonates exhibit anomalously
