Foraminiferal research lies at the border between geology and biology. Benthic foraminifera
are a major component of marine communities, highly sensitive to environmental influences …

Fine grained clastic sediments are very common in the interior deposits of ancient
epicontinental seas. Not only do they make up the gross lithology in these basins, but they …

Sedimentary habitats cover most of the ocean bottom and therefore constitute the largest
single ecosystem on Earth in spatial coverage. The benthic ecosystem contributes to human …

Meiobenthology is the science of the tiny animals that live in huge numbers in all aquatic
sediments. This fully revised and enlarged second edition emphasizes new discoveries and …

Abstract Mid-water oxygen minima (0.5 mll 1 dissolved O2) intercept the continental margins
along much of the eastern Pacific Ocean, off west Africa and in the Arabian Sea and Bay of …

Background Recent investigations suggest that biodiversity loss might impair the functioning
and sustainability of ecosystems. Although deep-sea ecosystems are the most extensive on …

The hypothesis that reducing conditions exist in localized zones of high organic matter,
termed microniches, was first suggested over a century ago, but only relatively recently have …

Under certain conditions, sediment cores from coastal settings subject to hypoxia can yield
records of environmental changes over time scales ranging from decades to millennia …

Although typically considered with a focus on high-resolution petrography, shale porosity
should not be thought of as a stand-alone petrographic feature. Shale and mudstone …

The pre-Ediacaran biomarker record has several characteristic features that distinguish it
from its Phanerozoic counterpart, including high concentrations of unresolved complex …
