Bathyal ostracodes from the Florida-Hatteras slope, the Straits of Florida, and the Blake Plateau
TLDR
In this article, the authors studied the relationship of numerous genera and species to bottom-water environmental conditions such as dissolved oxygen and bottomwater temperatures, and found that ostracodes display a narrow depth zonation controlled by dissolved oxygen, and species diversity is high for a bathyal zone.About:

North Atlantic Deepwater Temperature Change During Late Pliocene and Late Quaternary Climatic Cycles
Gary S. Dwyer,Thomas M. Cronin,Paul A. Baker,Maureen E. Raymo,Jeffrey S. Buzas,Thierry Corrège +5 more
TL;DR: In this article, the ratio of magnesium to calcium (Mg/Ca) in fossil ostracodes from Deep Sea Drilling Project Site 607 in the deep North Atlantic has been used to show that the change in bottom water temperature during late Pliocene 41,000-year obliquity cycles averaged 1.5°C between 3.2 and 2.8 million years ago (Ma) and increased to 2.3°C in the late Quaternary, coincidentally with the intensification of Northern Hemisphere glaciation.

Abrupt climate change and collapse of deep-sea ecosystems
TL;DR: Investigation of the deep-sea fossil record of benthic ostracodes during periods of rapid climate and oceanographic change over the past 20,000 years in a core from intermediate depth in the northwestern Atlantic indicates that deep- Sea ecosystems are not immune to the effects of rapidClimate changes occurring over centuries or less.

The platycopid signal: a means of detecting kenoxic events using Ostracoda
TL;DR: It has been shown that during Jurassic and Cretaceous kenoxic events, while other groups of benthonic Ostracoda severely decline and eventually disappear, the Platycopina tend to survive.
Journal ArticleDOI
Temporal latitudinal-gradient dynamics and tropical instability of deep-sea species diversity
TL;DR: Temporally dynamic LSDGs and unstable tropical diversity require reconsideration of current ecological hypotheses about the generation and maintenance of biodiversity as they apply to the deep sea, and underscore the potential vulnerability and conservation importance of tropical deep-sea ecosystems.

Benthic ostracods and deep water-masses in the Atlantic Ocean
R.V. Dingle,Alan Lord +1 more
TL;DR: Ostracod faunas at six locations are compared, and related to distributions in an Atlantic Ocean-wide data base, and their possible palaeo-oceanographic use is discussed in this article.

Faunal diversity in the deep-sea
TL;DR: In this article, the authors show that the diversity in the deep-sea benthos is not an artifact of sampling procedure and demonstrates that the deep seafloor is not faunally depauperate, as commonly believed.

Species Diversity: Benthonic Foraminifera in Western North Atlantic
Martin A. Buzas,Thomas G. Gibson +1 more
TL;DR: Diversity peaks occur at abyssal depths of greater than 2500 meters and 100 to 200 meters and the peak at 35 to 45 meters is due to species equitability, whereas the other two peaks correspond to an increase in the number of species.
