Deriving Forest Structural and Functional Metrics from Airborne and Ground-based Mobile Laser Scanning
(2025-11-26)This study examined the application of LiDAR-based methods, specifically Airborne Laser Scanning (ALS) and ground-based Mobile Laser Scanning (MLS), to evaluate forest structural metrics and their ecological functions ... -
The significance of chlorophyllous spores in the evolution and biogeography of ferns
(2025-05-15)Ferns, the second most diverse group of vascular plants globally, have evolved over millions of years colonizing diverse habitats across almost all continents. Ferns possess a suit of morphological and physiological traits ... -
Multifaceted Diversity in Forest Ecosystems Worldwide
(2025-02-25)Earth’s biodiversity faces numerous threats that endanger the delicate balance of ecosystems, highlighting the urgent need for integrated conservation strategies to preserve biodiversity. Forests in particular are critical ... -
Landscape Moderation of Ecological Patterns and Processes
(2025-02-25)This dissertation studies landscape moderation of ecological patterns and processes by employing different modeling approaches to investigate how landscape patterns influence ecological processes and, reversely, how ... -
Restoration of coniferous monocultures towards mixed broad-leaved forests in Central Europe – Patterns and processes of stand and vegetation diversification
(2024-11-05)Globally, forests provide essential ecosystem services to society, but their functionality is increasingly impaired by abiotic and biotic disturbances that are expected to further increase with predicted climate change. ... -
Functional traits of vascular plants on islands across spatial scales
(2024-02-22)Islands have unique and disharmonic floras, resulting from the filtering effects of dispersal and climate and, in some cases, their high evolutionary diversification rates. Due to their small size and distinct boundaries, ... -
Phylogenetic history and global diversity patterns of plants
(2024-01-26)Understanding where and how biodiversity originates and how it is maintained is one of the central questions in biogeography and macroecology. Phylogenies capture the evolutionary history of how lineages have diversified ... -
Global macroecology of ant-plant mutualisms: The role of biotic interactions in shaping species diversity and composition patterns
(2023-12-11)Understanding the mechanisms underlying patterns of species distribution and diversity is a central goal in ecology and biogeography. Biotic interactions have been acknowledged as important factors affecting species diversity ... -
New insights into drivers and passengers of tree architecture
(2023-06-27)Individual tree architecture and species composition perform a critical role in many ecological processes and resources a forest offers, such as wood value, biodiversity, and ecosystem stability. The structure and dynamics ... -
Overcoming Limitations in Biodiversity Data
(2022-12-02)Large-scale biodiversity data drive the research of the variation and interdependence among living organisms that sustain life. Taxonomic and point-occurrence validity of species, sample completeness, and consistency are ... -
Modelling, management and restoration of savannas in southern Africa
(2022-05-10)Context - Bush encroachment has been observed in southern African savannas for several decades. This form of land degradation reduces the abundance of (palatable) grass biomass on farms, which in turn can support less ... -
Quantifying three-dimensional stand structure of European beech forests along a management gradient
(2022-04-26)Forest structure is of functional importance for ecosystem stability and resilience, as well as for numerous other ecosystem functions and services. In this context, a high structural complexity can have a positive effect ... -
Diversity and composition of tree communities in the mosaic landscape of north-eastern Madagascar
(2022-01-14)In Madagascar, a large percentage of the rural human population faces multifaceted poverty and depends on agriculture and natural resources as main livelihood sources. Consequently, the country’s biodiverse natural ecosystems ... -
Diversity of oceanic island floras: a functional and taxonomic approach along gradients of environmental heterogeneity and across spatial scales
(2021-11-16)Oceanic islands are recognized for their unique biota, which include remarkable examples of trait evolution. This makes them excellent model systems for testing biogeographical and evolutionary hypotheses, as well as for ... -
Factors Influencing Fruiting Body Initation of Agaricomycetes
(2021-04-23)Macroscopic multicellular fruiting bodies of Agaricomycetes, commonly referred to as mushrooms, are the most complex developmental structures which exist in the kingdom of fungi. Fruiting bodies serve in production and ... -
Smallholder vanilla agroforestry in Madagascar: biodiversity, ecosystem services and yields in a land-use context
(2021-03-18)Land-use change threatens biodiversity and ecosystem services worldwide. Tropical areas are currently particularly affected: natural ecosystems are being transformed into large-scale monocultures or small-scale mosaic ... -
Modelling plant trait variability in changing arid environments
(2020-11-03)Communities in arid environments are especially vulnerable to global change because they experience highly unpredictable environmental conditions. The fate of communities in an uncertain future may be elucidated by ... -
Quantifying stand structure and structural complexity along a management gradient in temperate forests
(2020-10-01)The structure and structural complexity of forests influence many important characteristics of forest ecosystems, as well as their functions and services, such as ecosystem stability, maintenance of biodiversity and carbon ... -
Evaluation of Environmental Impacts of Short Rotation Coppice with Regard to the Amount and Quality of Groundwater Recharge
(2020-09-02)While there is broad agreement on the positive environmental impacts of short rotation plantations (SRC), possible negative impacts on groundwater recharge due to potentially high water consumption of trees on arabale land ... -
Analysing and modelling spatial patterns to infer the influence of environmental heterogeneity using point pattern analysis, individual-based simulation modelling and landscape metrics
(2020-05-11)One of the main goals of ecology is to understand processes underlying patterns. Because presumably all ecological processes are spatially explicit, especially spatial patterns can contain a lot of information about the ...
