Species lists of 14 Estonian coastal meadow sites with different management history

Marika Kose, Karin Kaljund & Kaili Kattai
The data were collected during July-August 2015 in locations with coordinates in dataset. The sites have unique names and their management has been evaluated as permanently managed, restored before 2005 and restored after 2005. Their condition is estimated on expert level as good or poor, regarding vegetation composition and height. The data were collected from 20 plots of the size 0,5 x 0,5 m. In the dataset the number marks in how many plots out...

Indrek Melts
The dataset collected from the typical and the most representative type of semi-natural grasslands in Satoyama landscape in Honshu island, Japan. Twelve grasslands were located on the Kaida Plateau between 1000–1300 m a.s.l. in Nagano Prefecture (approximate geographical coordinate of the study area: 35.931555N, 137.604300E) and six grasslands were located on the north-eastern foot of Mt. Fuji between 1000–1300 m a.s.l. in Yamanashi Prefecture (approximate geographical coordinate of the study area: 35.431819N, 138.812522E). The study sites...

Lake Peipsi 2017 (Littoral samples)

Reet Laugaste & Helle Mäemets
Phytoplankton samples were picked with bottle from among reed stands or from above thick beds of submerged plants from the depth 20-30 cm, were preserved in Lugol’s (acidified iodine) solution and counted under an inverted microscope (Utermöhl, 1958). 3 ml of preserved sample was settled overnight and counted in random fields or transects. Biovolumes of algal cells, colonies and/or filaments were calculated using assigned geometric shapes dimensions, and converted to biomass assuming the specific density...
