Drivers of forest dynamics: Joint effects of climate and competition
… thesis addresses different aspects of forest dynamics and possible changes due to climate change. Various modelling approaches are used to explore joint effects of climate and competition on forest dynamics with a focus on temperate forests. Motivated by scientific interest, this thesis …

Understanding tropical forest dynamics through remote sensing and deep learning
Protection of tropical forests is key to achieving global climate and biodiversity conservation goals. They play an essential role in carbon sequestration, water cycling, and nutrient exchanges, thereby regulating atmospheric composition and global climate patterns. However, they are under …

Forest dynamics at regional scales: predictive models constrained with inventory data
Forest ecosystems store more carbon than the atmosphere and harbour the majority of the world's biodiversity, yet their response to changing climate is uncertain. Forest simulation models make landscape-level predictions of forest dynamics by scaling from key tree-level processes, but models …

Flood Processes, Forest Dynamics, and Disturbance In the Congaree River Floodplain, South Carolina
… impacts. This study was designed to examine the forest development dynamics in abandoned meander landforms on the Congaree River floodplain, South Carolina in order to gain a better understanding of the forest successional responses to environmental gradients and historic logging …

Forest Dynamics Of Two Multi-Aged Hemlock-Mixed Mesophytic Forests In The Northern Cumberland Plateau, Kentucky
… role within the Appalachian mixed mesophytic forest of the eastern United States. However, the non-native hemlock woolly adelgid (HWA; Adelges tsugae Annand), a novel invasive colonizer, is significantly altering the natural processes within T. canadensis ecosystems. Few studies have …

Forest dynamics of pine- and oak-dominated communities on southeastern-facing slopes of Warm Springs Mountain, Virginia
… tracts of uninterrupted mixed pine and deciduous forest extending east into the George Washington National Forest. Limited documentation of past disturbances and their influence on WSM forests presents challenges for land managers desiring to understand historic conditions for these ecosystems. …

The effect of native forest dynamics upon the arrangements of species in oak forests-analysis of heterogeneity effects at the example of epigeal arthropods
… of epigeal spiders was studied in a natural forest and in a managed forest. Additionally the effects of small-scale microhabitat heterogeneity of managed and unmanaged forests were determined by analysing the spider assemblages of three different microhabitat structures (i. vegetation, ii. …

A Deep Learning Study on the Retrieval of Forest Parameters from Spaceborne Earth Observation Sensors
The efficient and timely monitoring of forest dynamics is of paramount importance and requires accurate, high-resolution and time-tagged predictions at global scale. Despite numerous methodologies have been proposed in the literature, existing approaches often compromise on accuracy, resolution, …

Growth and stand dynamics of Red maple-dominated forests in the Upper Great Lakes Region, USA
… tree species in North American temperate forests. Over the last several decades it has increased in abundance on upland sites throughout its range and today is perhaps the single most abundant tree species in eastern North America. Climate change and associated impacts on forest dynamics …

Subalpine Forest Tree Seedling Response to Drought
… drought is necessary to anticipate future forest dynamics with climate change, especially at the seedling stage given their role in shaping forest structure. We used precipitation reduction shelters to mimic drought for subalpine conifer seedlings (<em>A. lasiocarpa</em> and <em>P. …

A Holistic Analysis for Spatiotemporal Interdependencies of Deforestation, Forest Degradation and Landslide Susceptibility in NE Iran
Various biotic and abiotic agents are changing forests. Prolonged human activities substantially could cause not only different changes in forests but also could accelerate natural hazards in the Anthropocene. Despite several remote sensing-based research in forest changes, there is a need for a …

The effects of tree crown plasticity on the structure and dynamics of near-natural beech forests
A new individual-based forest model for the species beech (Fagus sylvatica L.) was developed and implemented. The model called BEEch Plasticity (BEEP) describes tree crown plasticity phenomenologically and is able to model aboveground competition for PAR on a process basis. The current debate about …

Forest Change Dynamics Across Levels of Urbanization in the Eastern US
The forests of the eastern United States reflect complex and highly dynamic patterns of change. This thesis seeks to explore the highly variable nature of these changes and to develop techniques that will enable researchers to examine their temporal and spatial patterns. The objectives of this …

The role of life history traits for coexistence and forest recovery after disturbance – a modelling perspective. Towards a better understanding of species-rich forests
Tropical forests are well known for their exceptional species richness – high diversity of plant species constitutes the basis for an equivalently rich fauna. An astonishing variety of plant life strategies has evolved, manifesting itself also in different compositions of life history traits in …

Modeling gap dynamics, succession, and disturbance regimes of mangrove forests
… and fauna and the human livelihood mangrove forests suffer a high loss rate mainly due to human activity. Aside from these impacts, natural forest disturbances exist more commonly in mangroves compared to other forests as a direct consequence of their exposed coastal location. Within this …

Monitoring the Knysna forest : species, community and forest responses
Forests are valuable ecosystems to society but are greatly threatened by changing factors from habitat conversion to climate change. South Africa's only extent of indigenous forest is predicted to disappear within the next 30 years. Many challenges are currently faced when trying to detect and …

Tree community assembly and biogeochemical processes along an elevational gradient in western Panama
Tropical montane forests (TMF) are unique ecosystems with remarkable contributions to global diversity and C cycle regulation. Understanding factors responsible of TMF dynamics are critical to predicting their plant community response to global change. Elevational and environmental gradients are …
