Survival of Liparis loeselii (L.) as an early successional species in Engure region described based on ecological peculiarities DURING the annual cycle

Open access


We present some results of a six-year (2008-2013) study in two localities of Liparis loeselii (L.) Rich. near Lake Engure. The annual cycle of L. loeselii, an early successional species, may indicate its potential survival in its typical wet habitat with fluctuating levels of water. Flowering of L. loeselii usually begins in the first decade of June and lasts for several weeks. If the initiation of development was delayed, leaves and inflorescence started to grow almost simultaneously. Development of the first fruit began during flowering and continued to August. Ripening of fruit and seeds occurred in September-October, and they were dispersed mostly by melt water of snow in spring, which is very important for populations in sites overgrowing with perennial herbs. The previous season capsules of L. loeselii remained till the middle of the next growing season; a part of the seeds remained in capsules and less than 1% of seeds had viable embryos. This may increase the survival potential of the population. The studies of herbarium records of L. loeselii in the area of Lake Engure showed that the annual cycles of L. loeselii have been similar and that the species has not responded drastically to climate change.
