▼ The loss of biodiversity can greatly influence ecosystem functions. Hence understanding the mechanisms behind plant species coexistence and maintenance of plant species diversity has important implications for biodiversity conservation and ecosystem function improvement. Environmental heterogeneity has long been thought to promote plant species coexistence and plant species diversity through increasing niche availability. Theoretical and observational studies have supported this hypothesis. However, convincing evidence for the heterogeneity-diversity hypothesis delivered by appropriate experiments is very scarce. The aim of my thesis was to examine the effects of different types of soil heterogeneity, i.e. the spatial variation in soil nutrients, soil pH and plant-soil feedbacks, on plant competitive interactions, species coexistence and plant species diversity. As a first step, I tested the potential of soil nutrient heterogeneity to promote plant species coexistence. In an experimental garden, two plant species with contrasting growth forms (i.e. phalanx vs. guerilla growth form) were planted in monocultures and in mixtures on homogenous and heterogeneous substrates consisting of low and high nutrient soil patches. In the plant mixtures, the two plants were either evenly distributed or planted in a clustered pattern. After two growing seasons, I found that soil nutrient heterogeneity increased the competitive ability of the competitive inferior species (guerilla growth form) and decreased that of the competitive superior species (phalanx growth form). The species with the guerilla strategy benefited more from the heterogeneous soil environment by selectively growing in high nutrient soil patches within heterogeneous soils. Apparently, soil nutrient heterogeneity does have the potential to promote plant species coexistence by slowing down the competitive exclusion process. Further, I tested whether soil nutrient heterogeneity can promote plant species diversity in an experimental community and whether these effects depend on the spatial scale at which species diversity (focal scale) and soil heterogeneity (grain size or patch size) are measured. I found that horizontal soil heterogeneity in soil nutrients reduced plant species richness, regardless of the patch size of the heterogeneity treatments. This decline in species richness is likely because the dominant species benefited from the heterogeneous environment, and outcompeted other plant species. Moreover, vertical heterogeneity in soil nutrients also reduced plant species diversity when high nutrient soil was located in the bottom layer. In this case only deep-rooting plant species had access to high nutrient soil, and could outcompete other plant species that cannot utilize the resources in the deeper layers. Spatial heterogeneity in soil nutrients only influenced species diversity when determined at the 10 cm × 10 cm patch scale but not when determined at the 40 cm × 40 cm plot scale. Therefore, soil nutrient heterogeneity indeed influenced plant… Advisors/Committee Members: Wageningen University, F. Berendse, T.M. Bezemer.

▼ The growth of trees depends on photosynthetic carbon gain by the leaves, which in turn relies on water and nutrient acquisition by the fine roots. Because the availability of carbon, water and nutrients fluctuates, trees can adjust their leaf and fine-root functional traits to maintain their resource uptake and growth rates. Aboveground, the variation in leaf traits is closely related to light availability, light uptake and tree growth. Within species, leaves show general, plastic responses to their light environment, so that trees can still intercept light when its availability changes. Across species, leaf traits are coordinated along a leaf economics spectrum (LES), which reflects species resource strategies. On the one end of this spectrum, acquisitive species have leaves that allow fast resource uptake and therefore fast tree growth. Conversely, species with a conservative strategy acquire resources more slowly, but retain them longer, so they can tolerate low resource availability. Belowground, the relationships between fine-root functional traits, water and nutrient availability and acquisition, and tree growth are expected to be similar to those aboveground, but are still poorly understood. Understanding these relationships is essential as tree growth results from the simultaneous uptake of above- and belowground resources. Therefore, this thesis examines how fine-root traits relate to growth, and focuses on across- and within-species variation in tree root traits. We first tested whether plant resource strategies can explain drought effects on tree growth across 10 common tree species that ranged from acquisitive to conservative species (Chapter 2). Based on tree-ring analyses, we found that the growth rates of all species were significantly lower in years with dry summers. Although the strength of these growth responses differed, these differences were not related to species resource strategies. However, when groundwater levels receded, acquisitive species grew slower but conservative species did not, which suggests root trait differences across these species. Drought effects on tree growth may thus not always be fully explained from an acquisitive or conservative resource strategy. We further evaluated whether a root economics spectrum (RES) parallel to a LES can explain variation in fine-root functional traits across species (Chapter 3). Our literature review shows no consistent evidence for an RES, due to three fundamental differences between fine roots and leaves. First, fine-root traits are not only aimed at increased resource uptake or conservation, but are also constrained by the soil environment. Second, the relationships between traits and function are far less clear for roots than for leaves. Third, the expected relationships between fine-root traits and resource uptake are obscured by mycorrhizal fungi. Revealing the links between fine-root traits, resource acquisition, and growth across species, therefore requires a multidimensional approach that… Advisors/Committee Members: Wageningen University, Frits Mohren, Liesje Mommer, Frank Sterck.

▼ Background Plant diversity influences ecosystem functioning. A positive relation between plant diversity and productivity above- and belowground has been established. Aboveground, this effect has been shown to be due to complementarity effects, interactions between species in a mixture that lead species to, on average, produce more biomass than expected based on their productivity in monoculture. The mechanisms underlying complementarity effects and the positive diversity-productivity relation are predicted to lie belowground, e.g. resource partitioning and/or facilitation. The relation between plant diversity and decomposition is less clear, and research on the diversity-decomposition relation belowground is limited. This is an important gap in biodiversity knowledge, as the decomposition of plant litter is the major source of nutrients and carbon in terrestrial ecosystems, and most plant litter in grasslands is belowground. Methods This thesis explored the effect of plant diversity on belowground productivity and decomposition. Belowground complementarity effects were quantified in the Jena Trait Based Experiment, and the diversity of or plasticity in species-specific vertical root distribution as underlying mechanism was tested. The plant diversity- root decomposition relation was quantified in the Jena Experiment and the Jena Trait Based Experiment. The role of root traits and the soil environment as mediating factors were tested. Major findings Plant diversity had a positive effect on root biomass production, and this relation was attributed to complementarity effects. The diversity in species-specific vertical root distribution did not explain complementarity effects, and thus, is not likely a major mechanism underlying the diversity-productivity relation. Species altered their vertical root distribution in response to inter-specific neighbours. The direction of this change differed between functional groups: grasses became shallower in mixture, forbs became deeper. This change did not explain species-specific belowground relative productivity (relative to monoculture productivity). Therefore, plasticity in vertical root distribution was not a major factor underlying belowground complementarity effects or the diversity-productivity relation. Functional group composition, not plant diversity, had a consistent effect on root decomposition. The presence or abundance of grasses consistently reduced root litter quality and decomposition. In the Jena Experiment, plant diversity had a negative effect on root decomposition, mainly due to shifts in functional group composition over a diversity gradient. In the Jena Trait Based Experiment, root decomposition was unaffected by plant diversity, but decreased as the abundance of grass roots increased. Root traits were found to be important in explaining variation in root decomposition. Conclusions Plant diversity had a positive effect on belowground productivity, which could be attributed to complementarity… Advisors/Committee Members: Wageningen University, D.

▼ Arctic ecosystems have been affected by severe climate change during the last decades. The increase in temperature in the Arctic has been almost double of the global rate of warming since the beginning of the 20th century. Like other ecosystems in the high latitude region, Arctic tundra appears to be extremely sensitive to the continuous warming of the past decades, which has led to dramatic vegetation changes such as rapid shrub expansion. While researchers are keen to talk about the shrubification of the Arctic tundra, there has been rather little attention for alternative vegetation shifts, such as those related to local permafrost collapse in lowland tundra. The general vegetation succession route of the ice-rich lowland tundra ecosystem is yet largely unknown. Therefore, we choose a typical Arctic lowland site (Kytalyk natural reserve) in the Northeastern Siberia to explore how vegetation is changing in this ecosystem, and how changes in the abiotic environment and vegetation succession interact. On the basis of field observations I assumed that the plant species composition of each vegetation patch at the study site changes continuously following cycles over time. To test this assumption, two multiple-year field experiments (Chapter 2 and Chapter 3) were carried out. In addition, we applied dendrochronological techniques (Chapter 4 and Chapter 5) and molecular tools (Chapter 4). On the basis of the results of these studies, I depicted a complete vegetation succession loop in the Arctic lowland tundra, which is closely related to the dynamics of the permafrost. In this vegetation succession loop, four stages with distinctive vegetation types have been identified. The Betula nana L. shrubs mainly dominate the well-drained elevated areas. In a field experiment, removal of B. nana shrubs resulted in abrupt permafrost degradation, rapid soil moisture increase and invasion of the grass species Arctagrostis latifolia (R. Br.) Griseb. After a short time period, when small ponds or drainages had developed, this fast-responding grass species is replaced by Eriophorum sedges. In the subsequent stage the Sphagnum mosses invade the sedge vegetation. The new Sphagnum moss carpets not only suppress the growth of Eriophorum sedges, but also create moist but unsaturated substrates that appear to be appropriate for the germination of B. nana seeds. These conditions provide new opportunities for B. nana shrubs to establish. The reproduction mode of B. nana at the study site has been studied using molecular tools (micro- satellites), as it may explain how existing B. nana patches developed and how shrub vegetation may expand in the future (Chapter 4). The conventional point of view is that sexual reproduction of perennial plants in the Arctic tundra, like B. nana, is rare due to the pressure of the harsh environment. However, the results of our molecular study (Chapter 4) tell a different story. While vegetative reproduction of B. nana is common, sexual reproduction of B. nana is more prevalent.

▼ Global climate has been warming up for the last decades and it will continue in this century. The Arctic is the part of the globe that warms fastest and is more sensitive to climate warming. Aboveground productivity of Arctic tundra has been shown to increase in response to warmer climates. However, belowground responses of tundra vegetation are still unclear. As the major part of plant biomass in tundra lies belowground, it is pivotal to investigate changes in the belowground parts of tundra vegetation for our understanding of climate warming effects on tundra ecosystems. To get a general idea of how belowground plant biomass may change in a warmer climate, we synthesized published data on the belowground biomass of tundra vegetation across a broad gradient of mean annual air temperature from −20 to 0 °C. We found that aboveground biomass of tundra biomass indeed increases with mean annual temperature as well as summer air temperature, while belowground biomass did not show a significant relationship with temperature. The increases in the aboveground biomass were significantly larger than belowground biomass, resulting in reduced below/above ratios at higher temperatures. The shifted biomass allocation with temperature can influence the carbon dynamics of tundra ecosystems. Future tundra studies need to focus more on the species or functional type composition of belowground biomass and species or functional type specific belowground responses to climate warming. To determine the seasonal changes and vertical distribution of root biomass of different plant functional types, we sampled roots at a Siberian tundra site in the early and late growing season, from vegetation types dominated by graminoids and shrubs respectively. We distinguished the roots of graminoids and shrubs, and found that shrub roots grew earlier and shallower than graminoid roots, which enables shrubs to gain advantage over graminoids at the early growing season when nutrient pulses occur during snowmelt and soil thaw. The deeper roots of graminoids can help them to be more competitive if climate warming induces more nutrient release in the deeper soil. In a soil thawing and fertilization experiment, we further investigated the effects of increased thawing depth and nutrient supply in the upper soil, which can be the consequences of climate warming, on root biomass and its vertical distribution. In this study we distinguished between the roots of grasses, sedges, deciduous shrubs and evergreen shrubs. The study was done in a moist tussock tundra site with similar abundance of the different plant functional types. We found that only sedges benefited from the increased thawing depth, probably through their deepest root distribution among the four functional types, while the shrubs, which were shallower-rooted, benefited from the increased nutrient availability in the upper soil. The deep-rooted grasses had the highest plasticity in vertical root distribution, which enabled them also to benefit greatly from the fertilization.… Advisors/Committee Members: Wageningen University, Frank Berendse, Monique Heijmans, Liesje Mommer.
