Abstract

Protected areas are a critical aspect towards safeguarding biodiversity with impacts on climate change and carbon sequestration. This study presents the results of the analysis on the living conditions offered to aquatic birds by the aquatic habitats of ROSPA0143 Upper Tisa protected area and highlights the importance of the aquatic habitats from Teplița for the conservation of biodiversity. Teplița aquatic system registers the largest number of aquatic species (66 out of a total of 68 for the entire protected area), of species that occur only here (22), of those nesting exclusively at Teplița (36.84% of the total nesting aquatic species) as well as the largest populations of aquatic species that are important for conservation. The vegetal carpet that supports the fauna has a simplified structure due to anthropic pressures, being comprised of three types of hygrophilous habitats, but with a high degree of ruderalization. Water quality analysis reveals a slightly more basic pH value for Tisa than for the 3 lakes in the area. Also, high values of dissolved oxygen and oxygen saturation determined for Tisa and the three lakes reflect a good level of oxygenation, above the minimum of 6.5-8 mg·L-1 required for healthy water. In accordance to water legislation, all measured parameters (i.e., alkalinity, Na, NH4+, NO2-, NO3-, Cl, iron) fall within the very good, good, and moderate quality classes. Dissolved copper, however, reveals a degraded water quality for lake 3 with a concentration slightly higher than the legal limit (0.123 mg·L-1).
来自tepliȚa的水生栖息地系统,是保护蒂萨河上游走廊生物多样性的重要元素
保护区是保护生物多样性的一个重要方面,对气候变化和碳封存有影响。本研究介绍了ROSPA0143上Tisa保护区水生栖息地为水禽提供的生存条件分析结果,并强调了Teplița水生栖息地对生物多样性保护的重要性。Teplița水生系统登记了数量最多的水生物种(整个保护区共有68种水生物种中的66种)、只在这里出现的水生物种(22种)、只在Teplița筑巢的水生物种(占总筑巢水生物种的36.84%)以及对保护具有重要意义的最大水生物种种群。由于人类活动的压力,支持动物群的植物地毯结构简化,由三种类型的亲湿栖息地组成,但具有高度的粗糙化。水质分析显示,蒂萨湖的碱性pH值略高于该地区的3个湖泊。此外,Tisa和三个湖泊的高溶解氧和高氧饱和度反映了良好的氧合水平,高于健康水所需的6.5-8 mg·L-1的最低水平。根据水法规,所有测量参数(即碱度、Na、NH4+、NO2-、NO3-、Cl、铁)均属于非常好、良好和中等质量等级。3湖溶解铜的浓度略高于法定限量(0.123 mg·L-1),水质有所下降。
