Coelastrum pascheri sp. n., a new green alga from lakes of the Bohemian Forest

Abstract

Coelastrum pascheri sp. n. is described. It is similar to Coelastrum morus W. et G. S. West sensu Skuja (1930) in the morphology of the free processes, but differs from it in cell size (it is significantly smaller, 13-16 µm) and in the number of cells in a cenobium (usually 4). The new alga was found in the littoral of some lakes: Černé jezero (Černé Lake), Grosser Arbersee and Kleiner Arbersee in the Bohemian Forest (Šumava, Böhmerwald) and also in Sphagnum within a small puddle in the Upolínová meadow in the Slavkovský les Mts.

Morphological Study of Coelastrum cambricum from the Peat Water of Palangka Raya, Indonesia

“…Coelastrum Nägeli 1849 is a genus of microalgae belonging to the scenedesmaceae family and currently has 31 taxonomically accepted species based on data in AlgaeBase (Guiry & Guiry, 2013). This genus is widely distributed in the aquatic environment around the world including freshwater and marine (Guiry & Guiry, 2013;Shubert, 2003;Lukavský, 2006). Coelastrum is a nonmotile green microalgae and lives in small colonies called coenobia which usually each coenobium consists of an even number of cells ranging from 4-32 cells or even more (Guiry & Guiry, 2013;Yu & Wong, 1975;Morris et al, 1973;Hindak, 1987).…”

“…Morphological characteristics are important in the identification of microalgae species because each species has its distinctive characteristics in terms of morphology including the group of microalgae that live to form coenobia (Kruk et al, 2010;Adam, 2022). Each species of microalgae that make up coenobia has differences in cell shape, arrangement pattern, and the number of constituent cells, especially Coelastrum Nägeli 1849, and this is one of the important morphological parameters in their identification (Lukavský, 2006;Chan, 1976;Richter & Schiller, 2012). Coelastrum pascheri is similar to Coelastrum morus but differs in significantly smaller cell size and the number of cells in a coenobium (Lukavský, 2006).…”

Coelastrum pascheri is similar to Coelastrum morus but differs in significantly smaller cell size and the number of cells in a coenobium (Lukavský, 2006). C. pascheri only has 4-8 cells in a coebium similar to C. microporum which is a much less cell count range than other Coelastrum species like C. morus, C. sphaericum, and C. cambricum which have 4-32 cells (Lukavský, 2006;Kim, 2013).…”

As there is no data that records the description of this genus from the peat water environment and by considering its potential, it is necessary to conduct a morphological study, especially the Coelastrum cambricum species which is commonly found in peat waters.…”

Integrated ecological research of catchment-lake ecosystems in the Bohemian Forest (Central Europe): A preface

“…Šantrůčková et al (2006) present new data on the decomposition rate and nutrient release from plant litter of Norway spruce forests in two Bohemian Forest catchments. The influence of recreational activity in the Bohemian Forest on stream water chemistry and phytobenthos is evaluated by Lukavský et al (2006).…”
