Abstract A total of 52 ostracod taxa (35 live spp. 17 subfossils) were collected from 70 shallow aquatic bodies with 11 different habitat types in Ağrı province (Turkey). Fabaeformiscandona acuminata is a new record for the Turkish ostracod fauna while 29 species were new for the province. Three types of habitats (stream, ditch and pond) contained the highest numbers of 24, 15, 11 species, respectively. Species were clustered into four main groups based on their distribution among habitats. Canonical Correspondence Analysis was able to explain 73.9% of the correlation between the 18 most frequently found species and five environmental variables. Water temperature and elevation were found to be the most effective factors on ostracods. Species with and without swimming setae tend to be found mostly in lentic and lotic habitats, respectively. Besides, species with swimming setae showed relatively higher ecological optimum and tolerance values for pH, electrical conductivity and water temperature than species without setae. The numbers of non-swimmer sexually reproducing species were twice the number of parthenogenetic species. Parthenogenetic species tend to have higher tolerance and optimum values for different environmental variables than sexual species. Results suggest a strong correlation among reproductive modes, swimming ability and ecological tolerances of the species.

不同繁殖方式的非海洋介形目（甲壳纲）在 ağrı 地区（土耳其）浅水体的物种多样性、游泳能力和生态耐受性的相关模式

摘要 从土耳其阿格里省 11 种不同栖息地类型的 70 个浅水体中收集了总共 52 个介形动物类群（35 个活体 17 个亚化石）。Fabaeformiscandona acuminata 是土耳其介形动物群的新记录，而该省有 29 种新物种。三种栖息地（溪流、沟渠和池塘）的数量最多，分别为 24、15、11 种。物种根据它们在栖息地中的分布被分为四个主要组。规范对应分析能够解释 18 个最常见物种与五个环境变量之间 73.9% 的相关性。发现水温和海拔是对介形虫最有效的因素。具有和不具有游动刚毛的物种往往分别主要出现在静水和激流栖息地。除了，与没有刚毛的物种相比，具有游泳刚毛的物种在 pH、电导率和水温方面表现出相对较高的生态最适值和耐受值。非游泳性有性繁殖物种的数量是孤雌生殖物种数量的两倍。孤雌生殖物种往往比有性物种对不同环境变量具有更高的耐受性和最佳值。结果表明该物种的繁殖方式、游泳能力和生态耐受性之间存在很强的相关性。孤雌生殖物种往往比有性物种对不同环境变量具有更高的耐受性和最佳值。结果表明该物种的繁殖方式、游泳能力和生态耐受性之间存在很强的相关性。孤雌生殖物种往往比有性物种对不同环境变量具有更高的耐受性和最佳值。结果表明该物种的繁殖方式、游泳能力和生态耐受性之间存在很强的相关性。
