Mesophyll conductance in gymnosperms
(Eesti Maaülikool, 2020)
Mesophyll conductance is the CO2 diffusion efficiency through the leaf from the substomatal cavity to chloroplasts located in plant cells. It is an important step determining photosynthetic efficiency next to photosynthetic ...
How phytoplankton pigments reflect historical and contempoarary status of large shallow lakes?
(Eesti Maaülikool, 2012)
Phytoplankton is the most important primary producer in the aquatic ecosystems and account for half of all photosynthetic activity on earth, thus creating the base for most aquatic food chains. It also plays key role in ...
Genetic diversity, genotypic structure and vulnerability of native populations of sickle medic (Medicago sativa ssp. falcata) in Estonia
(Eesti Maaülikool, 2013)
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
