“…(for more details see Pieri et al, 2013) and India (152 spp.) (Karuthapandi et al, 2014). However, we believe that numbers of Turkish nonmarine ostracods are underestimated because of lack of information about ostracod diversity from other regions of Turkey.…”

-To understand the distribution and ecological characteristics of non-marine ostracods, the Poisson Method was applied to a total of 41 taxa (26 recent and 15 sub-fossil) from 111 (out of 120) aquatic bodies of Adyaman Province, Turkey. All taxa were new records for the area and Schellencandona insueta and Gomphocythere n. sp. were the first records for Turkey. According to the Poisson method, ostracods were randomly distributed among all sampling sites (P > 0.05). This is especially true for the cosmopolitan species (Candona neglecta, Heterocypris incongruens, Ilyocypris bradyi and Psychrodromus olivaceus) with broader ecological tolerance ranges to different environmental variables. According to canonical correspondence analysis (CCA), the first two axes explained 77.4% of the relationships and the most effective variables were found as electrical conductivity (F = 3.987, P = 0.002, l = 0.31), water temperature (F = 3.582, P = 0.002, l = 0.17), pH (F = 3.510, P = 0.002, l = 0.12) and elevation (F = 4.491, P = 0.02, l = 0.37). Additionally, the ratio (numbers of taxa/site = 2) was found same at lower (450-550 m) and higher (1359-1459 m) ranges, in which H. incongruens and I. bradyi were the most common species found from different habitats. Overall, random distribution of ostracods among sampling sites seemed to be more affected by random distribution of cosmopolitan species at the regional level than the non-cosmopolitans whose distribution may be uniform or clumped since they prefer certain types of ecological conditions at local level.

“…Neale (1977) proposed that five species of ostracods (Pseudocypretta maculata Klie, 1932, Hemicypris pyxidata (Moniez, 1892, Strandesia marmorata (Brady, 1886), Strandesia purpurascens (Brady, 1886) and S. weirzejskii Tressler, 1937) found in rice fields in the central and southern parts of Sri Lanka were invasive from Indonesia, then known to be the only place where these species also occur. Since then, three of these species, Pseudocypretta maculata, Hemicypris pyxidata, and Strandesia purpurascens, have been reported from India (see checklist of Indian species by Karuthapandi et al, 2014), so the likelihood that they are invasive in Sri Lanka has diminished somewhat.…”

Ostracods are very common in rice fields and they can have a significant influence on the rice field ecosystem. They can reach very high densities, often higher than other meiofauna, and their activities can have both positive and negative effects on rice harvests. They directly affect nutrient recycling through excretion, and indirectly by physically disturbing the soil and releasing minerals, thus improving rice growth. On the other hand, ostracods grazing on nitrogen-fixing cyanobacteria potentially reduce rice yields. Rice is a primary staple food for over half of the world's population, and therefore ostracods can have a significant impact on human food supply. The origin of the rice field ostracod fauna is poorly known, but many rice field ostracods are considered invasive, especially in southern Europe, and from rice fields they have the potential to spread to surrounding natural habitats. Despite their invasive potential and ecological effects on the rice field ecosystem, very little is known about the diversity, ecology and impacts of rice field ostracods in many rice-producing countries. One hundred and ninety-two named ostracod species/subspecies have been reported from rice fields in 26 countries and states worldwide in the published literature; for over three-quarters of riceproducing countries, no data are readily available, and for most of the countries that have available data, diversity is clearly underreported. Most species that have been documented from rice fields belong to the Cyprididae (78%), a family that makes up approximately 43% of the 2500+ non-marine ostracod species. A further six families (Candonidae, Darwinulidae, Entocytheridae, Ilyocyprididae, Limnocytheridae and Notodromadidae) form the remainder of rice field ostracods. Twenty-two percent of the species reported from rice fields are sexually reproducing, 18% have mixed reproduction, but are mostly asexual, and for 60% males are unknown, and are probably entirely asexually reproducing species. This review and checklist of rice field ostracods are presented to facilitate further research on this group in rice field habitats, research that is crucial for food security in many regions

A new ostracod genus, Tuberocandonagen. nov., was collected from Honeycut Hollow Springs, Texas, USA Morphological comparisons and cladistic analyses showed that the new genus displays several different features (e.g. presence of two tubercules on each of the valves, numbers of A1 segments, shape of A2 claws, shape and presence of two claw-like setae on the clasping organs, absence of d2 and dp setae on T2 and T3, absence of alpha and beta setae on Md, shape of hemipenis) from other genera of the tribe. Including the new species, the number of non-marine ostracods known from inland waters of Texas is now 118 species in 45 genera. With the aim of documenting ostracod biodiversity in Texas (USA) by including fossils, we sought documents published from 1927 to 2022 and were able to list 673 ostracod taxa belonging to 142 genera. Among the fossils, 73 ostracods were the oldest records during the Pennsylvanian period (ca. 310 mya), while there were only 42 taxa reported from the Holocene. The Eocene had the highest number of ostracods (126 taxa). In comparison, the living species had only 18 of 673 taxa that were considered nonmarine forms. There are only six species in common with the fossils and recent records. These results suggest the potential for relatively high ostracod species richness and diversity in Texas. This is indeed strongly supported by the present study and the described new genus and its type species (Tuberocandona leonidasisp. nov.).
