INFORMATION ABOUT BIOTOPE
关于生物栖息地的信息
Description of the area surrounding the biotope: Lachuá is an oligotrophic and meromictic karstic lake in the region of Alta Verapaz and belongs to the southern upper reaches of the Usumacinta River drainage basin. The lake is located in the centre of the Laguna Lachuá National Park (LLNP, 15°53’ N, 90°40’W), south of El Petén and the south-eastern Mexico border. There are 5 affluents which flow into the main lake. My biotope is based around the River Peyán, which is positioned on the Western side of the basin. The Peyan River forms the main water inflow and the Lachua River its outflow. The area is lined with tropical rain forest. Riparian areas around the Río Peyán are composed of mainly trees, palms and submerged grasses.
生物栖息地周边地区的描述：拉丘亚是阿尔塔韦拉帕斯地区的一个贫营养性和分层混合的喀斯特湖，属于乌苏马辛塔河上游流域的南部。该湖位于拉丘亚国家公园（LLNP, 15°53’ N, 90°40’W）的中心，位于埃尔佩滕以南和墨西哥东南部边界。有 5 条支流流入主湖。我的生物栖息地以佩亚恩河为中心，该河位于盆地西侧。佩亚恩河是主要的水流入，拉丘亚河是其流出。该地区覆盖着热带雨林。佩亚恩河岸边的河岸地带主要由树木、棕榈和沉水草组成。
Description of the underwater landscape of the biotope: The Río Peyán is one of 3 permanent affluent river mouths to the main Lake. Habitat is reported to be a mainly calcareous rocky bank where the mouth opens on to muddy shore. Canopies of shading trees contiguously go down into water surface, where there are lots of tree trucks, roots and general wood and leaf litter mainly composed of surrounding trees and palms. Substrate is reported to be sand and gravel, but mainly a dominant emphasis towards gravel and small rocks. A greater number of fish species is recorded around the River mouths and littoral zones.
对生物群落水下景观的描述：佩亚恩河是主湖的 3 个永久支流河口之一。栖息地被报告为主要是石灰岩河岸，河口敞开于泥泞的岸边。遮阳树的树冠连续延伸至水面，那里有许多树木的树干、根系和主要由周围树木和棕榈组成的木材和落叶堆积物。底质被报告为沙子和砾石，但主要强调的是砾石和小石块。记录到更多的鱼类物种在河口和滨岸带区域。
Description of the parameters of the habitat: Water is reported to be very clear with a blueish tinge. Water velocity can be slow to moderate depending on the seasons. Increased velocity is reported during the wet season. Water parameters recorded are T=28.2oC, pH=8.0, C=960.5 μS, H=1081 mg/l, S=390 mg/l, NP=0.21 mg/l.
对栖息地参数的描述：水被报告为非常清澈，带有蓝色调。水流速度根据季节可慢至中等。在雨季报告有增加的水流速度。记录到的水参数为 T=28.2℃，pH=8.0，C=960.5 μS，H=1081 mg/l，S=390 mg/l，NP=0.21 mg/l。
