Site-specific energy crop planning: potential land resource, pedo-climatic and economic risks
(Eesti Maaülikool, 2012)
In recent decades, renewable energy production has become the focus of energy policy. For meeting the target of increasing the share of renewable energy, biomass use is claimed to be essential. Since there has been a ...
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 ...
Epidemiology, impact on herd health and control of bovine herpesvirus 1 in Estonian dairy cattle herds
(Eesti Maaülikool, 2012)
The objective of the present doctoral thesis was to assess the herd-level and within-herd prevalence of bovine herpesvirus 1 (BHV-1) infection in Estonian dairy cattle and estimate the sensitivity and specificity of the ...
The characterization and modelling of the dynamic behavior of hard-to-machine alloys
(Eesti Maaülikool, 2012)
Because of their excellent mechanical, physical and chemical properties
even at elevated temperature, titanium and nickel-base alloys are the materials
suitable for the production of several parts and components in ...
Systematics and Ecology of Selected Taxa of Wood-decaying Basidiomycetes
(Eesti Maaülikool, 2012)
Within a long period, the main groups of aphyllophoroid macrofungi: polypores and corticioids have been dealth with under the collective family names Corticiaceae and Polyporaceae. Recent studies have shown their polyphyletic ...
The Effects of Natural and Anthropogenic Factors on the Physiological State of Insects
(Eesti Maaülikool, 2012)
1. A novel O2 respirometry system termed coulometric respirometry was developed able to record oxygen convective uptakes (passive sucction inspiration) during the F-phase. It is not possible to measure and record these O2 ...
The Effect of Plant Residues Management and Fertilization on Plant Growth and Organic Carbon Content in Soil
(Eesti Maaülikool, 2012)
The main hypothesis of present thesis is that the effect of plant residues left on the surface of the sward to decompose on the growth of plants and content of soil organic carbon (SOC) is influenced by the management ...
Correcting and Calibrating Airbone Laser Scanning Intensity Data Using Naturally Available Targets
(Eesti Maaülikool, 2012)
Airborne laser scanning (ALS) has been used widely due to its three dimensional information. Additionally to coordinates, ALS systems record also intensity values that describe the objects backscattering properties. The ...
The Structuring Role of Lake Conditions for Aquatic Macrophytes
(Eesti Maaülikool, 2012)
Macrophytes play an important role in lake ecosystems, which provisionally can be divided into an active role consisting of modifying in-lake processes and creating habitat for other groups of biota, and a passive role ...
