“…Higher gamma diversities of ostracods have been recorded from shallow marine environments than from the deep-sea, but these differences have been shown to be correlated to the sampling effort, which is much larger in the continental shelves, diminishing gradually towards the abyss and even more extremely towards hadal areas (e.g. Brandão et al 2019b: Figure 2). The relationship of the ostracod alpha diversity and bathymetry is variable.…”

“…The group is also a common inhabitant of more rarely investigated environments, such as subterranean (Karanovic 2007), interstitial waters (Tanaka 2014), and submarine caves (Chiu et al 2016(Chiu et al , 2017. In the deep sea, ostracods have been recorded from all habitats and depth zones, like continental margins, abyssal plains, trenches, wood falls, hydrothermal vents, and cold seeps (Karanovic and Brandão, 2015;Brandão et al 2019b).…”

“…The main goal of these expeditions was to study the species composition and distribution patterns of bottom animals, as well as to assess the faunal relationships in the deep-sea ecosystems of the Sea of Okhotsk and the Kuril-Kamchatka Trench separated by such a natural barrier as the Kuril Islands Brandt et al, 2019). As a result, numerous species from different taxonomic groups of animals were described, the composition of macro-and meiofauna and the patterns of distribution of the main taxonomic groups of animals were studied, the faunal relationship and levels of endemism of these deep-sea areas were estimated (e.g., Maiorova, 2018, 2019;Alalykina, 2018;Brandt et al, 2018Brandt et al, , 2019Polyakova, 2018, 2019;Fukumori et al, 2018Fukumori et al, , 2019Kamenev, 2018aKamenev, ,b, 2019Kamenev, , 2020Maiorova and Adrianov, 2018a,b;Brandt, 2018, 2020;Mironov et al, 2018Mironov et al, , 2019bBorisanova and Chernyshev, 2019;Brandão et al, 2019;Mordukhovich et al, 2019;Schmidt et al, 2019;Alalykina and Polyakova, 2020;Maiorova and Adrianov, 2020;Saeedi and Brandt, 2020). However, the analysis of the quantitative distribution of macro-and meiofauna in the Kuril Basin has not been completed, and only preliminary results of the macrofauna abundance study have been reported for the Kuril-Kamchatka Trench (Lins and Brandt, 2020).…”

The Kuril Basin and the Kuril-Kamchatka Trench are two interconnected deep-sea ecosystems both located in one of the most highly productive regions of the world’s oceans. The main distinguishing features of these deep-sea ecosystems are the low oxygen concentration in the near-bottom water in the Kuril Basin, and the high hydrostatic pressure in the trench. We investigated the abundance of meio- and macrobenthic nematodes and macrofauna on the Kuril Basin floor (depths of 3,300–3,366 m) and in the Kuril-Kamchatka Trench area (depths of 3,432–9,539 m), as well as the influence of some environmental factors on the quantitative distribution of bottom fauna. This was not studied so far. The study also focused on the species composition and quantitative distribution of Polychaeta and Bivalvia, which were dominant in abundance among macrofaunal samples. The main factors influencing the quantitative distribution of macrofauna and nematodes were depth, oxygen concentration, and structure of bottom sediments. The Kuril Basin bottom communities are characterized by a high abundance of nematodes and macrofauna, a high species richness of polychaetes, and a pronounced dominance of small-sized species of Polychaeta and Bivalvia, which are probably more tolerant to low oxygen concentrations. Compared to the Kuril Basin, the Kuril-Kamchatka Trench area (at depths of 3,432–5,741 m) had a more diverse and abundant macrofauna, and a very high abundance of meio- and macrobenthic nematodes. In the trench (at depths more than 6,000 m), the diversity of macrofauna and the abundance of macrobenthic nematodes decreased, while the abundance of macrofauna increased with increasing depth. On the trench floor, the macrofaunal abundance was highest due to the high density of populations of several bivalve and polychaete species, apparently adapted to the high hydrostatic pressure on the trench floor. Obviously, the high primary production of surface waters supports the diverse and abundant deep-sea bottom fauna in the studied areas of the northwestern Pacific. Furthermore, a large number of animals with chemosynthetic endosymbiotic bacteria were found in the bottom communities of the Kuril Basin and the Kuril-Kamchatka Trench. This suggests a significant contribution of chemosynthetic organic carbon to functioning of these deep-sea ecosystems.

The first ostracods known from the Lycian Nappes in southwestern Turkey are here reported, adding to the scientific understanding of marine ostracods during the Cordevolian, early Carnian, Late Triassic. The Karapınar Formation exposed at the Ağılıovası Yayla section yielded five species, including the typical Late Triassic Mirabairdia longispinosa Kristan-Tollmann, Nodobairdia mammilata Kollmann and Polycope pumicosa schleiferae Kozur. Their taxonomy is discussed and the ontogenetic development of Nodobairdia mammilata is described for the first time. In spite of the limited significance of this poor fauna for palaeoenvironment reconstitution, it points to a deposition in the offshore subtidal zone under moderate water depth, in line with previous interpretations. The palaeobiogeographical distribution of marine ostracods during the Late Triassic is updated and discussed. It implies that communication ways between the Palaeotethys and Neotethys oceans were already opened during the Cordevolian, slightly earlier than the Julian as previously proposed.
