The response time of North Atlantic climate to changes in high-latitude deep-water formation during the last deglaciation is still unclear. Here the authors show that gradual changes in Nordic ...Two sediment cores were obtained from Kasado Bay, a moderate-polluted enclosed bay in Japan, to examine anthropogenic impacts on Ostracoda over the past ca. 70 years.We analyzed ostracode abundance and diversity, grain size, and CHN, and used 210 Pb and 137 Cs as the dating method. The present study showed that cross-plot comparisons of ostracode abundance and each environmental factor, based ...Jun 1, 2022 · Biodiversity databases are changing the longevity of data in the era of open science. They also represent a collaboration opportunity in analyzing large-scale (paleo)biological patterns beyond a local project or a time scale. Ostracods, microscopic crustaceans, are a component in many biodiversity databases. They live in most kinds of aquatic ...

Callistocythere alata was sensitive and Bicornucythere bisanensis has a strong resistance for anthorogenic pollution in ostracode species. Thus, the relative frequencies of these two ostracodes can be used as an indication of such pollution.
