Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Physiological controls on seawater uptake and calcification in the benthic foraminifer Ammonia tepida [PDF]

open access: yes, 2009
To analyze the relation between seawater uptake and calcification, we incubated juveniles of the benthic foraminifer Ammonia tepida with various fluorescent probes and visualised them afterwards with confocal laser scanning microscopy. Vesicle membranes,

Seasonal distribution of genetic types of planktonic foraminifer morphospecies in the Santa Barbara Channel and its paleoceanographic implications [PDF]

open access: yes, 2003
We present data on the temporal distribution of planktonic foraminifer genotypes (small subunit (SSU) ribosomal (r) RNA gene) and morphospecies (sediment traps) collected during 1999 in the Santa Barbara Channel.

Neogene and quaternary planktonic foraminifer biostratigraphy and biochronology in Baffin Bay and the Labrador Sea [PDF]

open access: yes, 1989
During Ocean Drilling Program Leg 105, 11 holes were drilled in the Labrador Sea and Baffin Bay. Site 645 in Baffin Bay was drilled to a depth of 1147 meters below seafloor (mbsf); planktonic foraminifers were recovered in the upper 110.3 m and in a ...

On two cases of male dimorphism in dwarf spiders (Araneae: Linyphiidae)

open access: yesArachnologische Mitteilungen, 2018
Diplocephalus cristatus (Blackwall, 1833) is confirmed as a dimorphic species, having two morphs:cristatus and foraminifer. This view was first proposed by Georgescu (1969), but not supported in literature. Diplocephalus foraminifer (O. Pickard-Cambridge,
