Many herbal plants stay active as long as there is no frost and snow. Here we want to quantify the photosynthetic activity in relation to ambient temperature as well as to what extend this is influenced by strong temperature fluctuations. Methods: Photosynthetic activity CO 2 flux of rapeseed Brassica napus under a constant light source will be measured at different temperatures. For simulation of temperature fluctuations, we will use greenhouses or climate chambers.

Influence of temperature and photoperiod on bud dormancy and phenology in trees BA or MA. Understory geophytes in deciduous forests complete their reproduction very early in the year before the tree canopy closes. Therefore, they are indicators of climate change in late winter. Here, differences in geophyte phenology between climatically different locations are to be studied. Influence of drought on spring phenology of European Beech BA.

We observed spring phenology of about woody species in the Arboretum for 3 years now. The leave unfolding dates differ by about days between the earliest and the latest species.

Bachelorarbeit, Tipps Zu Themenfindung.

Aiming to understand the phenological strategies of the species from the ecological and evolutionary point of view, spring phenology can be understood as a trade-off between the advantage of an early growing season on one hand and the risk of frost damage to the fresh leaves on the other. Age and turnover of tree roots in a drained and re-wetted alder swamp 1 MA or 2 BA. Dendrochronology is a common tool to determine the age of trees. Less attention is hereby put on the belowground part of the plant, because it is often overlooked that also roots, not only stems, form the so-called growth rings.

The longevity of roots determines the turnover rates how much biomass enters and exits the system which, on the other hand, defines how much organic matter is available for decomposers in these systems. Alder swamps are forested wetlands and therefore function as important carbon stores. Peat, the most important carbon store, can only be formed when production of plant biomass exceeds its decomposition. In this context, the age distribution of roots of Alnus glutinosa in different depth levels shall be investigated and either compared between trees growing in a rewetted and a drained Alder swamp as a master thesis or investigated separately in two bachelor thesis.

Putting the root growth of an extreme year into perspective MA or 2 BA. Here, the root growth dynamics in three different types of drained and re-wetted peatlands alder carr, percolation mire and coastal mire are assessed by the minirhozotron technique. The same observations occurred already in the extremely dry and warm year , when water tables even in the rewetted fens dropped below cm.

Here, we now aim at putting this extreme year into perspective to another, more normal year. Methods: Using minirhizotrons root cameras , root growth in space and time is analysed at drained and re-wetted peatlands in MV, which will be visited regularly during the growing season. A driving license is needed and an own car is a merit travel costs will be covered. Lag-effects of different winter soil temperature regimes on fine root growth and decomposition rates in beech forests varying in winter harshness BA or MA. Effects of global warming will be most pronounced in winter. A reduction in insulating snow cover due to warmer atmospheric temperature, however, could induce soil cooling during winter.

This may affect plant roots leading to shifts in root phenology and rooting depth. Furthermore, decomposition rates of organic material may decrease due to a disturbed decomposer community. Previous work in the project indicated that there may be long-lasting effects of the one-time soil temperature manipulation for root growth and decomposition in particular.

Therefore, this thesis tests for lag-effects of different soil temperature regimes on root growth by non-intrusive root photography minirhizotron technique and on decomposition rates by a tea-bag-decomposition experiment. The candidate will accompany us to all sites to take root pictures and excavate tea bags. Presumably, six one-day field trips will start in Greifswald.

One field trip will include 3 experimental sites in Poland, with overnight stay close to Dansk. Travel costs are paid for. The thesis builds up on knowledge from a previous Bachelor thesis.

Methods: Minirhozotrone root imaging during the field trips in Germany and Poland; quantification of fine root length with software rootfly or comparable software e. Root phenology of wetland plants in response to water regime 1 MA or 2 BA. Data sampling: regularly during the field season of April to September , with individual timing to be discussed.

Plant roots have key roles in ecosystem function and are of special importance in fens, where roots and rhizomes form peat and thus are the main contributors to large carbon stores. However, little is known about the root dynamics of different species, how they respond to changes in water table height, and how species respond to competition.

Methods: Using minirhizotrons root cameras in a mesocosm facility to assess root growth and root architecture in fen species originating under different water table regimes. Typha and Phragmites offer options for sustainable agriculture of rewetted peatlands, i. In such rewetted systems, water table and nutrient level are controlled by management. Here, we will test for optimal water table and nutrient availability for the production of high-quality products. Methods: Water table and nutrient levels are experimentally manipulated in a gradient-design mesocosm experiment at Greifswald.

Here, quantity and quality of the produced biomass will be studied. In parallel, a field trial site will offer the option to compare to field conditions.

Warum ist ein gutes Thema für die Bachelorarbeit so wichtig?

Several topics for theses are available in this general setup. Response of a coastal heathland to drought and grazing during different successional stages BA or MA. Coastal heathlands are dominated by Calluna vulgaris. They are old cultural landscapes of high conservation value. However, atmospheric nitrogen deposition and management cessation have led to increased competition by grasses and woody species, thereby endangering this ecosystem type. In a field experiment on the island of Hiddensee, we test if climate change-induced drought would further exacerbate these developments and if simulated sheep grazing might retard it.

All this is realized in two successional stages, one with young and vigorously-growing Calluna plants and the other with over-aged and partly dying Calluna. The whole experiment is part of the International Drought Experiment , a network which runs comparable drought experiments all over the globe. Recovery after extreme drought in a coastal heathland BA or MA. The extremely dry summer caused massive dieback of Calluna vulgaris and Empetrum nigrum in the coastal heathlands of Hiddensee. Extremes like this drought will happen more frequently with climate change.

Recovery after the extreme is therefore crucial for the longterm perspective of this ecosystem type. Methods: Visible damage and several plant parameters were monitored in August at about plots.

These plots shall be revisited to quantify recovery. In addition, about 30 visibly dead individuals were marked in September and recovery of those is also to be checked. Finally, aerial pictures from October can be used to quantify extant of the damage by remote sensing techniques and check recovery on the ground. Presence and activity of soil mesofauna in drained and re-wetted peatlands MA. Soil mesofauna e. Here, we want to assess the presence and activity of soil mesofauna in three different types of drained and re-wetted peatlands alder carr, percolation mire and coastal mire.

There is the potential to go to Uppsala to work on soil fauna identification. Methods: Assessing presence of soil fauna, and their activity via bait lamina sticks. A driving license is a merit. Importance of snow cover for understory plants in boreal forests. Snow cover is crucial for winter survival of boreal forest understory plants, as it protects them from severe air frost.

With climate change, however, snow cover is getting thinner and less continuous. Here, snow cover is experimentally manipulated by snow-out shelters since in a boreal forest. Understory performance in this treatment can be compared to untreated reference conditions and a one-time manipulation of snow cover. Methods: Determination of understory cover higher plants and mosses by point-intercept method in an existing field experiment.

Phenotypic plasticity and local adaptation in seedlings of Fagus sylvatica across Europe MA. Phenotypic plasticity and local adaptations allow plant species to cope with heterogeneous environmental conditions in space and time.
