“…Because of their small size, high abundance, and excellent fossil record, fossil ostracods (microcrustaceans) have been widely used to reconstruct Quaternary environmental conditions including water depth, salinity, temperature, oxygen, and pollution, especially in marginal marine sediments (Boomer and Eisenhauer, 2002;Cronin, 2015;Frenzel and Boomer, 2005;Horne et al, 2012;Ruiz et al, 2005). In the northwestern Pacific and Indo-Pacific there are numerous deltas (Woodroffe et al, 2006) hosting accumulated Holocene marine sediments.…”

Abstract. Fossil ostracods have been widely used for Quaternary paleoenvironmental reconstructions, especially in marginal marine environments (e.g., for water depth, temperature, salinity, oxygen levels, pollution). But our knowledge of indicator species autoecology, the base of paleoenvironmental reconstructions, remains limited and commonly lacks robust statistical support and comprehensive comparison with environmental data. We analyzed marginal marine ostracod taxa at 52 sites in Hong Kong for which comprehensive environmental data are available. We applied linear regression models to reveal relationships between species distribution and environmental factors for 18 common taxa (mainly species, a few genera) in our Hong Kong dataset and identified indicator species of environmental parameters. For example, Sinocytheridea impressa, a widely distributed euryhaline species throughout the East and South China Sea and the Indo-Pacific, indicates eutrophication and bottom-water hypoxia. Neomonoceratina delicata, a widely known species from nearshore and estuarine environments in the East and South China Sea and the Indo-Pacific, indicates heavy metal pollution and increased turbidity. The 18 taxa used for this study are widely distributed geographically and divided into the following groups: widespread (throughout the northwestern Pacific and Indo-Pacific regions), temperate (South China Sea to Russia (Sea of Japan coast) and Japan), subtropical (Indo-Pacific to the East China Sea), tropical (Indo-Pacific and South China Sea), and globally distributed. With statistical support from ecological modeling and comprehensive environmental data, these results provide a robust baseline for ostracod-based Quaternary–Anthropocene paleoenvironmental reconstructions in the tropical–extratropical northwestern Pacific and Indo-Pacific. Highlights. We provide a robust baseline for ostracod-based (microscopic Arthropods) paleoenvironmental reconstructions from Quaternary and Anthropocene marginal marine sediments. The studied species have wide distributions over the tropics and extratropics of the northwestern Pacific and Indo-Pacific. Ecological modeling has established ostracod species as reliable indicators for paleoenvironmental reconstructions.

We applied linear regression models to reveal relationships between species distribution and environmental factors, and identified indicator species of environmental parameters. For example, Sinocytheridea impressa and Neomonoceratina delicata indicate botttom-water hypoxia &#8211; eutrophication, and heavy-metal pollution - increased turbidity, respectively. Many taxa are widespread throughout the northwestern Pacific &#8211; Indo-Pacific regions, including temperate (South China Sea to Japan and Russia), subtropical (i.e., Indo-Pacific to the East China Sea), and tropical (i.e., Indo-Pacific and South China Sea) taxa. With statistical support from ecological modeling and comprehensive environmental data, These results provide a robust baseline for ostracod-based Quaternary-Anthropocene paleoenvironmental reconstructions in the tropic&#8211;extratopic northwestern Pacific and Indo-Pacific.

“…Thus, ostracods are a widely used microfossil group in the reconstruction of various palaeoceanographic and palaeoclimatological changes. They have been successfully applied in the reconstruction of past sea-level, temperature, salinity, and other environmental changes (Frenzel and Boomer, 2005;Yasuhara and Seto, 2006;Iwatani et al, 2012;Cronin, 2015). However, methane seep ostracods remain poorly investigated, and any ostracod species, genera, or faunas endemic or specific in methane seep environments have not been known until now (Karanovic and Brandão, 2015).…”

Abstract. Despite their high abundance and diversity, microfossil taxa adapted to a particular chemosynthetic environment have rarely been studied and are therefore poorly known. Here we report on an ostracod species, Rosaliella svalbardensis gen. et sp. nov., from a cold methane seep site at the western Svalbard margin, Fram Strait. The new species shows a distinct morphology, different from other eucytherurine ostracod genera. It has a marked similarity to Xylocythere, an ostracod genus known from chemosynthetic environments of wood falls and hydrothermal vents. Rosaliella svalbardensis is probably an endemic species or genus linked to methane seeps. We speculate that the surface ornamentation of pore clusters, secondary reticulation, and pit clusters may be related to ectosymbiosis with chemoautotrophic bacteria. This new discovery of specialized microfossil taxa is important because they can be used as an indicator species for past and present seep environments (http: //zoobank.org/urn:lsid:zoobank.org:pub:6075FF30-29D5-4DAB-9141-AE722CD3A69B).
