Understory Composition, Seedling Growth, and Snag Frequency Across a Water-Limited Forest Landscape
… more uncertain. These changes can affect forest plant communities directly by altering demographic rates, and indirectly through interspecific interactions. Impacts can vary among forest strata. Here, I asked how different forest strata respond to topographic variation in soil moisture and …

Population Dynamics of Ouachita Dusky Salamanders (Desmognathus brimleyorum) in a Managed Forest Landscape
<p>With anthropogenic alteration of landscapes increasing world-wide, managed forests are increasingly important as providers of ecosystem services including habitat for numerous wildlife species. It is crucial to maintain a balance between timber production and conservation of biodiversity on …

Forests of the future: ecosystem services in a forest landscape facing significant changes
… of ecosystem services. Traditionally, many landscapes were managed to maximise the delivery of just a few benefits, such as food or timber, but this was often at the expense of other potential benefits, such as carbon sequestration or water supply. The ecosystem services approach aims to …

Understanding Forest Landscape Response to Global Climatic Change: An Uncertainty Evaluation Based on Spatial Modeling
The forest ecosystem is one of the world's most important ecosystems that would be substantially affected by future global climatic changes in temperature, CO2, precipitation and radiation. Climatic changes may affect tree species physiology, abundance, distribution; forest community …

Spatial distribution of canopy gaps in a tropical forest landscape and its influence on the tree community
Tropical forests are highly dynamic and diverse ecosystems, but our understanding of the processes that shape the local abundance and spatial distribution of the tree species within them is still rather limited. In particular, the role of disturbance in determining compositional variation in …

Movements of adult western toads, Bufo boreas, in a managed forest landscape and the incidence of a disease in southwestern British Columbia
… of this thesis were to (1) determine how forest fragmentation affects western toad movement behaviour; and (2) determine if there is any evidence of the infectious disease, the chytrid fungus (Batrachochytrium dendrobatidis), in this species in British Columbia. I used radio-telemetry to …

Analysis of the ecological principles underpinning forest landscape restoration: a case study of wood cricket (Nemobius sylvestris) on the Isle of Wight (UK).
… more important than processes operating at the landscape scale in terms of species persistence, especially for those species that show high dependence on woodland habitat conditions and have limited dispersal ability. The applicability of landscape-scale approaches to woodland restoration …

Impacts of group selection harvest openings on the reproductive success of the Solitary Vireo (Vireo solitarius alticola)
… alticola) were studied on an extensive mature forest landscape in 1994 and on three sites harvested using the group selection method in 1995. Pairing success was 88% on the unharvested site in 1994, however it was lower on the harvested sites in 1995 (53.8%). Low reproductive success was …

Reconciling conservation, agriculture and household welfare: Testing the suitability of the land sparing and sharing model in Western Uganda
… the multiple requirements that people place on landscapes. The land sparing and sharing model is a simple and powerful way of framing the trade-offs between agricultural production and biodiversity conservation but one that has been subject to much criticism, not least for its failure to …

The Role of Trust in Collaborative Natural Resource Management
This dissertation examines how trust develops in landscape level collaborative natural resource management efforts. I took a case study approach to research four projects in the Collaborative Forest Landscape Restoration Program (CFLRP). I conducted qualitative analysis of interviews, notes and …

WOODLAND CARIBOU AS ECOLOGICAL DRIVERS OF FIR WITCHES' BROOM INFECTIONS ON THE SLATE ISLANDS
… herbivory on The Slate Islands altered the forest landscape and ground flora resulting in the emergence of the rust fungi, <em>Melampsorella caryophyllacearum</em>. This rust alternates between chickweeds and balsam fir, where it causes a broom deformity. My study identified factors …

Elk hunting on Turnbull National Wildlife Refuge: impacts on elk movement and aspen regeneration
… (Populus tremuloides) cover less than 10% of the forest landscape, yet support a disproportionate diversity of native plants and animals. When elk (Cervus elaphus) become overabundant, browsing prevents aspen regeneration, reduces survival, and consequently impacts local biodiversity. Given this, …

Effectiveness of Treatments to Reduce Rhododendron maximum and Promote Tree Seedling Regeneration in the Southern Appalachians
… plays a dynamic role in the southern Appalachian forests. Commonly located on mesic sites, this understory shrub forms dense thickets that greatly reduce the amount of light available to herbaceous and woody plants found on the forest floor. Past research has shown that silvicultural methods can …

Effects of experimental disturbance on multi-taxa assemblages and traits: conservation implication in a forest-open landscape mosaic
… networks are to be created in modernised landscapes. Within Europe much of the biodiversity interest is in semi-natural habitats that exist as isolated reserves. This thesis aimed to test the connectivity potential of open habitat for lowland heathland biodiversity within a mosaic forest …
