Baseline for ostracod-based northwestern Pacific and Indo-Pacific shallow-marine paleoenvironmental reconstructions: ecological modeling of species distributions

Abstract: 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 compr… Show more

“…No other typical deep-water genera, such as Cytheropteron and Argilloecia, occurred in this sample, even though these genera are known to be abundant in upper bathyal depths in the Indo-Pacific region (Iwatani et al, 2018). In addition to the above-mentioned abundant genera, many other warm (often tropical) water indicator genera occurred in this sample (e.g., Cytherelloidea, Neomonoceratina, Paijenborchellina, Ruggieria, Phlyctenophora, and Stigmatocythere) (Wood and Whatley, 1994;Yasuhara et al, 2018;Hong et al, 2019;Shin et al, 2019). Loxoconcha and Aurila are typical phytal genera, although they include sediment-dwelling species (Kamiya, 1988;Yasuhara et al, 2002bYasuhara et al, , 2005Szczechura, 2006;Yasuhara and Seto, 2006;Reich et al, 2015).…”

“…The assignment to Bicornucythere has continued to be used in many recent studies (e.g. Hong et al ; Irizuki et al ; Yamada et al ). We are considering a full taxonomic review and revision of the generic assignment but this is beyond the scope of the present study.…”

“…Bicornucythere bisanensis is widely distributed in brackish water bodies along the northern coast of Vietnam, the coasts of China and Japan (e.g. Okubo ; Zhao et al ; Zhou et al ; Yasuhara & Irizuki ; Irizuki et al ; Yasuhara & Seto ; Irizuki et al ; Tanaka et al ; Hong et al ; Hong et al ). In the ostracod assemblage from core DK06, sample WT‐08, B. bisanensis was represented abundantly by a suite of adult and juvenile instars, indicative of a low‐energy autochthonous thanatocoenosis (Boomer et al ) with little or no post‐mortem transport or sorting.…”

“…Sinocytheridea impressa and N. delicata are shallow marine ostracods from the superfamily Cytheroidea (Brandão et al, 2020), which are mainly distributed in Asian waters (Hong et al, 2019;Tanaka et al, 2011). The abundance of both species 45 has been used as an indicator of sea level transgressions (Chunlian et al, 2013).…”

“…delicata is common in well-ventilated moderate saline bays (Hong et al, 2019;Irizuki et al, 2005). Paleoenvironmental investigations have focused on the study of assemblages of these two species, but not the elemental composition of their shells as indicator of environmental marine variables, such as temperature or salinity.…”
