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 …

Trophic ecology is the study of feeding interactions and food acquisition by organisms. It
includes the causes and consequences of those behaviours at all levels of biological …

The history of Earth's biodiversity is punctuated episodically by mass extinctions. These are
characterized by major declines of taxon richness, but the accompanying ecological …

This work analyses the distribution of living benthic foraminiferal assemblages of surface
sediments in different intertidal areas of Ria de Aveiro (Portugal), a polihaline and …

This work analyses the distribution of heavy metals in the sediments of Ria de Aveiro
(Portugal) assessed by total digestion and sequential chemical extraction of the sediments …

The ecological quality status of the NE region of the Guanabara Bay (SE Brazil), one of the
most important Brazilian embayments, is evaluated. For this purpose, sediment samples …

Benthic foraminifera (protists) have long been recognized as sensitive indicators in studies
on natural and human-induced environmental, paleo-environmental, and climate change …

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 …

The assimilation of inorganic compounds in foraminiferal metabolism compared to predation
or organic matter assimilation is unknown. Here, we investigate possible inorganic …
