Spatial and temporal patterns are determined by a variety of biotic and abiotic conditions, among all in shallow, Mediterranean, heavily modified water bodies. Lake Karla's, a multi-service reservoir, re-establishment begun 60 years after the natural lake was dried. This research is aimed at linking a series of environmental drivers with the phytoplankton functional groups during a dry year after the lake's refilling period, to investigate seasonal and spatial dynamics, and to get an insight into lake's ecology for both monitoring and management purposes. In situ physical and chemical measurements, along with water and plankton sampling took place monthly from May 2014 till March 2015. A combination of direct ordination, multivariate statistical analyses and distance-based approaches were used to examine spatial and temporal patterns and to test dissimilarities among and within the stations. Phytoplankton was assorted in Reynolds’ functional groups. The lake's hydrology was also modelled. The research results presented Karla lake as a homogeneously degraded system. The major environmental parameters affecting phytoplankton community were ortho-phosphates and temperature in a lake with long retention time. The five functional groups that were dominant during the survey were comprised by representatives of cyanobacteria, followed by chlorophytes and diatoms, many of them indicative of warm, shallow, turbid, nutrient-rich waters. Phytoplankton revealed a seasonal trend with prolonged summer, low differentiation among seasons and uninterrupted winter succession. The relations and patterns found are useful for monitoring, as for management purposes to enhance the reservoir's capacity.

时空格局是由各种生物和非生物条件决定的，其中所有条件都是在浅水，地中海，经过大量改造的水体中进行的。天然湖泊干60后的60年，开始重建多用途水库卡拉湖。这项研究的目的是在湖泊补充水后的干燥年份将一系列环境驱动因素与浮游植物功能群联系起来，以调查季节和空间动态，并深入了解湖泊的生态状况，以进行监测和管理。从2014年5月至2015年3月，每月进行一次原位物理和化学测量，以及水和浮游生物的采样。多元统计分析和基于距离的方法用于检查空间和时间模式，并测试站之间和站之间的差异。浮游植物被归入雷诺的功能组中。该湖的水文也被模拟。研究结果表明Karla湖是一个均匀退化的系统。影响浮游植物群落的主要环境参数是邻位-湖泊中的磷酸盐和温度保持时间长。在调查中占主导地位的五个功能组由蓝细菌的代表组成，其次是绿藻和硅藻，其中许多代表温暖，浅薄，浑浊，营养丰富的水。浮游植物显示出季节性趋势，夏季延长，季节间差异低，冬季演替不间断。所发现的关系和模式可用于监视，以及用于管理目的以增强水库的容量。
