The Impact of Global Climate Change on Tropical Forest Biodiversity in Amazonia
… of the potential impact of climate change on biodiversity have been biased towards species of high latitudes. This situation results from a lack of detailed knowledge about the distribution of tropical biodiversity, and from the smaller degree of warming expected at low latitudes. However, …

Effects of land-use change on tropical forest biodiversity: a multi-scale assessment in the Brazilian Amazon
A Amazônia Brasileira compreende cerca de 40% das florestas tropicais do globo, abrigando uma enorme parte da biodiversidade mundial. Todavia, taxas alarmantes de desmatamento são encontradas por toda a região amazônica. Demandas cada vez mais altas por recursos naturais são uma das maiores ameaças …

Is Chir Pine Displacing Banj Oak in the Central Himalaya? Socioeconomic Implications for Local People and the Conservation of Oak Forest Biodiversity
… Five sites with three different types of forests (banj oak, chir pine and mixed oak-pine) were sampled to compare the diversity of their vegetation and to assess the impact of this ongoing conversion on biodiversity. Soil samples collected from oak and pine forests were analyzed and …

Assessing processes of long-term land cover change and modelling their effects on tropical forest biodiversity patterns – a remote sensing and GIS-based approach for three landscapes in East Africa
… assessment of changes in different tropical rainforest areas in East Africa. In order to assess the effects of the derived changes in land cover and forest fragmentation, the study made use of spatially explicit modelling approaches within a geographical information system (GIS) to extrapolate …

Systematic conservation planning and South Africa's Forest Biome: An assesment of the conservation status of South Africa's forest and reccomdentations for their conservation
… conservation plan for the entire South African forest biome. This was done by addressing the following questions: What is the current state of the forest biome? How well are forests protected? How threatened are they? What are the conservation priorities, and what needs to be done to improve …

Maple Sugar Bush Management and Biodiversity Conservation in Eastern Ontario, Canada
… in Eastern Ontario might contribute to biodiversity maintenance and conservation and therefore be promoted as a form of rural sustainable development. Ontario government policy seeks to actively promote actions that strengthen the province’s rural communities and protect biodiversity. …

Building A Mechanistic Understanding Of Biodiversity And Ecosystem Functioning In Forests
Biodiversity supports the productivity, resilience, and functioning of ecosystems over time. However, the underlying mechanisms of how biodiversity begets ecosystem function are still being uncovered. I sought to understand how tree diversity could influence local resource pools of light, water, …

Patrones de diversidad de especies leñosas en los bosques españoles a diferentes escalas espaciales: efectos de las perturbaciones selvícolas y otros factores ambientales y de paisaje
Biodiversity provides many services to humans and influences many ecosystem functions. Among forest biodiversity indicators, species richness is the most frequently used, although all components of biodiversity are important. Patterns of species richness and their drivers are scale-dependent. In …

Landscape Influences on Spatial Patterns of White-tailed Deer Herbivory and Condition Indices in the Central Appalachian Mountains
… have had an increasingly negative effect on forest biodiversity and a growing influence on forest succession. In Virginia, the combination of these factors has prompted establishment of deer population management goals and policies designed to support conservation of biodiversity, forest …

Assessing indicators of forest sustainability using lidar remote sensing
… a suite of attributes to assess and monitor forest sustainability. Each attribute is in turn evaluated using a variety of indicators. Recently, digital remote sensing technologies have emerged as both alternative and supplement to traditional monitoring techniques, with light detection and …

Remote Sensing Characterization of Ecosystem Structure and Functional Types to Inform on Biodiversity Conservation in the Lowland Chocó Rainforest
… structure and functional types to inform on biodiversity conservation. This work is motivated by a guiding hypothesis that increased degradation of tropical forest biodiversity due to human activity results in in measurable changes in ecosystem processes that can be detected using remote …
