This study investigates the ostracod assemblages obtained from a sediment core from a paleolake in the Sağlık plain in south-central Anatolia (Turkey). In addition to ostracods, oxygen and.

carbon stable isotopes of ostracod shells were analysed and pollen analysis of the core undertaken. The sediments comprise the Late Glacial and early Holocene interval with an approximate ¹⁴C age from 18,000 to 6700 ¹⁴C years ago, after applying a correction for reservoir effects. Eight podocopid ostracod species were recorded, among them Cyprideis torosa and Candona sp. which were used for stable oxygen and carbon isotope analyses. C. torosa dominated during the Late Glacial while Candona sp. dominated most of the early Holocene assemblages. Both forms of C. torosa disappear abruptly close to the onset of the Holocene. Around this time, ostracod preservation was dominated by many black coloured valves and carapaces.

Based on ostracod assemblage data and isotope analyses, relatively wet phases were identified for the Older Dryas, Younger Dryas, and during the mid-Holocene at around 7500 ¹⁴C years ago. Relatively dry phases were identified during the Allerød interstadial, at the end of YD, and at about 6700 ¹⁴C years ago. An oligotrophic and brackish lake persisted until shortly before the end of the YD, when, according to the δ ¹³C values, conditions gradually became more eutrophic. The sudden disappearance of C. torosa at the end of the YD seems the consequence of anoxic bottom water conditions and/or eutrophication.

Alternating wet and dry phases characterize the early Holocene, with a longer period of wet and oligotrophic conditions around 7500 ¹⁴C years ago (ca. 8300 calBP). Ostracod assemblages and isotope records indicate a dry and more productive lake around 6700 ¹⁴C years ago (ca. 7550 calBP).

这项研究调查了从安纳托利亚（土耳其）中南部萨克利克平原古湖中的沉积岩心中获得的成虫纲组合。除虫，氧气和。

分析了纲壳的碳稳定同位素，并对核心进行了花粉分析。沉积物包括晚冰期和全新世早期间隔与近似¹⁴从18000Ç年龄到6700 ¹⁴ Ç年前，施加校正储层效应之后。记录到了八种足类龙骨种类，其中Cyprideis torosa和Candona sp。用于稳定的氧和碳同位素分析。C. torosa在晚冰河时期占主导，而Candona sp。在大多数早期全新世组合中占主导地位。两种形式的C. torosa在全新世爆发时突然消失。大约在这个时候，成虫的保存主要是由许多黑色的瓣膜和甲壳组成的。

根据成龙的组装数据和同位素分析，在¹⁴ C年前7500年左右，在较早的树架，较年轻的树架和全新世中期发现了相对较湿的相。在Allerød星际期间，YD结束时和¹⁴ C的大约6700年发现了相对干燥的阶段。贫营养和咸水湖泊持续直到不久YD，结束之前时，根据δ ¹³ C值，条件逐渐变得更富营养化。YD末尾的C. torosa突然消失，似乎是缺氧的底水条件和/或富营养化的结果。

干湿交替阶段表征全新世早期，用湿和贫营养条件7500周围较长时间¹⁴ Ç年前（约8300 calBP）。兽脚类动物的组合和同位素记录表明，在¹⁴ C年前的6700年前后（约7550 calBP），一个干燥且生产力更高的湖泊。
