Short summary
We revisited a 19th-century taxonomic study on Hong Kong marine ostracods (the first study on Chinese marine ostracods) to compare it with a 21st-century survey. We found substantial differences in species, likely related to differences in pollution and climate between the 19th and 21st centuries. This discovery highlights the importance of historical ecology. Early natural historians documented "natural baseline" ecosystems before the substantial human presence with industrialization.

Oxygen-depleted ocean waters have increased worldwide. In order to improve our understanding of the impacts of this oxygen loss on marine life it is essential that we develop reliable indicators that track the negative impacts of low oxygen. We review various indicators of low-oxygen stress for marine animals including their use, research needs, and application to confront the challenges of ocean oxygen loss.

Through the first large-scale study of meiobenthic ostracods from the diverse and productive reef ecosystem in the Zanzibar Archipelago, Tanzania, we found that the diversity and composition of ostracod assemblages as controlled by benthic habitats and human impacts were indicative of overall reef health, and we highlighted the usefulness of ostracods as a model proxy to monitor and understand the degradation of reef ecosystems from the coral-dominated phase to the algae-dominated phase.

This study analyzed microfaunal assemblages in surface sediments from 52 sites in Hong Kong marine waters. We selected 18 species for linear regression modeling to statistically reveal the relationship between species distribution and environmental factors. These results show environmental preferences of commonly distributed species on Asian coasts, providing a robust baseline for past environmental reconstruction of the broad Asian region using microfossils in sediment cores.

We present 2000 years record of properties in the subsurface, near surface and surface water masses SW off Svalbard in relation to climate changes. Planktic foraminifera and their related proxies show warm Roman and Medieval periods and cold Dark and Little Ice Ages. Close correlation of sea surface temperatures recorded by planktic foraminifera with total solar irradiance implies solar activity as a dominant factor influencing sea surface conditions on the decadal-multidecadal time scale.

A sediment core collected from a pockmark field on the Vestnesa Ridge (~80N) in the Fram Strait is presented. Our results show an undisturbed sedimentary record for the last 14 ka BP and negative carbon isotope excursions (CIEs) during the Bølling-Allerød interstadials and during the early Holocene. Both CIEs relate to periods of ocean warming, sea-level rise and increased concentrations of methane (CH4) in the atmosphere, suggesting an apparent correlation with warm climatic events.

Short summary
We studied ostracod assemblages from an 1800-year sediment record from a Jamaican lake to evaluate causes of change and to test a previous interpretation from a Late Pleistocene record, which suggested that lake-level change was the main control. We found that, rather than being a simple response to changing lake level, ostracod assemblage changes are a complex response to a range of factors. Our findings may have relevance to the interpretation of ostracod assemblages in other similar lakes.

Short summary
We report extant ostracods from the Co To Islands in northeastern Vietnam and identified 77 ostracod species. On the basis of the comparison of ostracod species reported from adjacent areas, the assemblages from the Co To Islands have a relationship with those of the Kymerian Province, especially with that of South China, and have little relationship with the East Indian Province. Our result is useful for the reconstruction of the dispersal of the Kymerian ostracods during the Quaternary.

Wangshangkia, a new genus of Ostracoda, is described from the Late Devonian in Dushan of Guizhou, South China. This genus belongs to the family Bairdiocyprididae Shaver, 1961 and includes two new species, i.e. Wangshangkia dushaniensis and W. bailouiensis. The new genus is characterized by a wide ventral carina with radial striae. It is reported from the Famennian of South China and disappeared just below the Devonian–Carboniferous boundary. Wangshangkia is essentially a benthic crawler.

Short summary
Microscopic-sized fossils adapted to a particular chemosynthetic environment (such as cold methane seep) are poorly known. Here we report a new ostracod (small crustacean with high fossilization potential) species probably endemic to a cold methane seep environment. This new discovery is important because there is a wealth of microscopic-sized fossils in geological records and this species can be used as an indicator fossil for past cold methane seep environment.
Microscopic-sized fossils adapted to a particular chemosynthetic environment (such as cold...
