The diet of juvenile pikeperch Sander lucioperca in lakes Peipsi and Võrtsjärv: relations between long-term changes in the fish communities and food resources in large shallow lakes
(Eesti Maaülikool, 2012)
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 ...
Productivity and nutrient retention of lakes on seasonal, interannual and morphometric scales
(Eesti Maaülikool, 2012)
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 ...
Long-term changes in the Estonian flora and measures for conservation
(Eesti Maaülikool, 2014)
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 ...
Changes in the biochemical composition of apple (Malus domestica Borkh.) fruits depending on rootstock and calcium treatment
(Eesti Maaülikool, 2013)
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 influence of cultivar and natural enemies on raspberry beetle (Byturus tomentosus De Geer)
(Eesti Maaülikool, 2013)
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, ...
Effects of natural and anthropogenic pressures on variations in the water quality of large lakes
(Eesti Maaülikool, 2014)
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 ...
Associations between metabolic profile and coagulation ability of bovine milk effect of feeding and lactation stage
(Eesti Maaülikool, 2013)
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 ...
Biomass from semi-natural grassland for bioenergy
(Eesti Maaülikool, 2014)
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 ...
Knowledge, learning and legitimacy in participatory multi-level ecological network governance
(Eesti Maaülikool, 2014)
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 ...
Possibilities to Affect Antioxidant Properties of Strawberries and Some Methodical Aspects in Their Determination
(Eesti Maaülikool, 2015)
It is generally acknowledged that genotype, cultivation conditions and postharvest technologies might have an effect on some antioxidant compounds in strawberries, but the extent to which different measures impact total ...
