The thesis addresses three important problems of plant population biology and ecology by studying Estonian populations of sickle medic Medicago sativa L. ssp. falcata (L.) Arcangeli (hereafter falcata), as a model plant ...

Pikeperch, Sander lucioperca (L.), is a pelagic predator, which plays a key role in many inland water bodies of the temperate zone by structuring populations at lower trophic levels (Frankiewicz et al., 1997; Dörner et ...

Despite the considerable percentage of inland waters in the temperate zone land cover, their role in the global carbon balance is not clear and the existing data suggest large type specific differences. Respiratory CO2 ...

Increased human influence causes loss of habitats of plant species and changes in species distribution. Combining changes in species distributions and abundance with their functional traits enables to evaluate species of ...

In the Baltic States, the main goal in apple- related research has been to find out the winter hardy rootstocks and cultivars. The focus in yield quality studies has been on apple size, appearance and storability. Different ...

The raspberry beetle (Byturus tomentosus De Geer), which is the main raspberry pest, causes large yield losses and reduces fruit quality of raspberry. Control of the raspberry beetle relies on synthetic chemical insecticides, ...

An understanding of the factors that drive the water quality of large lakes is critical to the protection of such waterbodies. In the present study, the contributions made by riverine nutrient loading, sediment resuspension ...

Most of the milk produced in Europe is converted into cheese by enzymatic coagulation. Therefore the coagulation ability of milk is of great economical interest and widely studied trait. Yet, there is no clear genetic or ...

One of the under-utilised potential agricultural sources of bioenergy feedstock is the herbaceous biomass obtained from semi-natural grasslands. For biodiversity maintenance, it is important that semi-natural grasslands ...

Ecological networks aim to integrate biodiversity conservation with sustainable spatial development. Their governance in Europe is shaped by the interplays between multiple actors from various levels along spatial and ...
