• Differential regulation of release of leaf stress volatiles: from terpene synthase gene expression to emission responses under heat, ozone and wounding stresses 

  Kanagendran, Arooran (Eesti Maaülikool, 2018)

  Plants release a wide array of biogenic volatile organic compounds both constitutively and upon stress. BVOCs play key roles biologically and ecologically. In addition, the emission responses of stress volatiles act as one ...

• Induction of volatile organic compound emissions from leaves upon ozone and methyl jasmonate (MeJa) treatments 

  Li, Shuai (Eesti Maaülikool, 2018)

  Plants biosynthesized a wide variety of volatile organic compound (BVOCs) consisting of volatile isoprenoids, LOX products, saturated aldehydes, benzenoids, and several hydrocarbon volatiles. BVOCs have a considerable ...

• The effect of natural variability on the assessment of ecological status of shallow lakes 

  Tuvikene, Lea (Eesti Maaülikool, 2018)

  The dissertation contributes to the improvement of large lake monitoring, demonstrating that besides following the class boundaries of ecological status established by law, reliable status estimates of such lakes require ...

• The sublethal effects of neurotoxic insecticides on the basic behaviours of agriculturally important carabid beetles 

  Tooming, Ene (Eesti Maaülikool, 2017)

  Sublethal effects of pesticides on behavioural endpoints are poorly investigated in nontargeted beneficial arthropod predators important as nartural enemies of many agricultural pests. In this ecotoxicological study, ...

• Effects of natural and anthropogenic pressures and disturbances on the macrophytes of Lake Peipsi 

  Palmik, Kadi (Eesti Maaülikool, 2017)

  Macrophytes play an important role in aquatic ecosystems. Their temporal and spatial distribution is governed by various natural and anthropogenic pressures and disturbances. The aim of the thesis is to study the effect ...

• Change in Estonian natural resource use: the case of wild food plants 

  Kalle, Raivo (Eesti Maaülikool, 2017)

  The use of wild food plants is one example of the importance of biocultural diversity. Wild food plants are, in the context of this work, those plants that grow without the direct intentional help (cultivation or management) ...

• High-Frequency Measurements - A New Approach in Limnology 

  Meinson, Pille (Eesti Maaülikool, 2017)

  Until recently, time consuming and costly manual measurements have been predominating in lake research and monitoring. Usually, this kind of measurements do not provide sufficient temporal and spatial resolution if any. ...
