The oceans are losing oxygen (O 2), and oxygen minimum zones are expanding due to
climate warming (lower O 2 solubility) and eutrophication related to agriculture. This trend is …

We report systematic transmission electron microscope (TEM) observations of the cellular
ultrastructure of selected, small rotalid benthic foraminifera. Nine species from different …

The genetic diversity, morphology and biogeography of Ammonia specimens was
investigated across the Northeast (NE) Atlantic margins, to enhance the regional (palaeo) …

Living Ammonia species and an inventory of dead assemblages from Adriatic subtidal,
nearshore environments were investigated at four stations off Bellaria, Italy. Ammonia …

Foraminifera are ubiquitous marine protists with an important role in the benthic carbon
cycle. However, morphological observations often fail to resolve their exact taxonomic …

Brejo do Espinho coastal lake (LBE) is one of the few places in the world where dolomite
[CaMg (CO 3) 2] is precipitating in the modern environment under microbially induced …

In mudflats, interactions and transfers of nutrients and secondary metabolites may drive
ecosystems and biodiversity. Foraminifera have complex trophic strategies as they often rely …

Heavy metals are known to cause deleterious effects on biota because of their toxicity,
persistence and bioaccumulation. Here, we briefly document the ultrastructural changes …

Abstract 86 surface sediment samples and a core (CDZS38) from the Changjiang River
Estuary (CRE) and its adjacent area were collected to investigate the environmental …

Acid-resistant, chitin-like organic linings of foraminiferal tests in palynological assemblages
are commonly considered reliable indicators of marine transgressions despite sparse …
