Abstract:

This theoretically focused thesis investigates the use of soft classification techniques for identifying and quantifying landscape structures in a real landscape (the forest-savannah intergrade in the Beni savannahs, Bolivia). Two soft classification approaches are used in this study: a Semantic Import Model and a Fuzzy Clustering Model. Landscape structures usually are measured using hard classifications and quantified with landscape metrics. However previous research has highlighted problems with the interpretation and reliability of the resulting metric values. Soft classification technique

Abstract:

This is a study in which landscape architecture is theoretically related to the "textile art." It establishes a theoretical analogy of the landscape as a kind of textual manifestation, "the landscape is a textile," and aims to establish new resemblances that show how the landscape and textile arts are related, not only with regards to the elements of composition, or to similarities between the elemental relationships that exist in both these arts, but to how the study of structure and form in the production of textiles may influence our understanding of the textile nature

Abstract:

The influence of habitat loss on biodiversity is related to a set of non-linear processes, which strongly affect isolation and connectivity and determine both extinction and colonization rates. Landscape changes due anthropogenic disturbances are driving not only species loss per se, but also loss of functions performed by those species, which could have important impacts on the provision of ecosystem services and ecosystem function. The objective of this dissertation is to move beyond our current understanding about landscape processes underpinning bird persistence and avian-mediated pest con

Abstract:

Floodplains are amongst the most productive and biodiverse ecosystems. The structure and functioning of floodplains is controlled by the interaction of intermittent inundation with the floodplain landscape. These interactions create highly complex and dynamic ecosystems that are difficult to study at large scales. Consequently, most research of floodplains has been conducted at small spatial and temporal scales. Inundation of floodplains can extend over many square kilometres, however, which unifies the floodplain landscape into an integrated ecosystem operating at the landscape scale. The lac

Abstract:

Habitat variation is considered as an expression of biodiversity at landscape level in addition to genetic variation and species variation. Thus, effective methods for measuring habitat pattern at landscape level can be used to evaluate the status of biological conservation. However, the commonly used model (i.e. patch-corridor-matrix) for spatial pattern analysis has deficiencies. This model assumes discrete structures within the landscape without explicit consideration of “transitional zones” or “gradients” between patches. The transitional zones, often called “ecotones”, are dynamic and hav

Carbon export from high elevation ecosystems is a critical component of the global carbon cycle. Ecosystems in northern latitudes have become the focus of much research due to their potential as large sinks of carbon in the atmosphere.

Ecosystem services, the benefits that people receive from ecosystems, depend on the movement of organisms and matter across landscapes, as well as the biodiversity and ecosystem functions that are present.

This is particularly true in agricultural systems, where human activities to maximize the ecosystem service of food production often lead to the decline of other important ecosystem services.

Climate can also affect rodent population dynamics and the virus survival in the environment, as well as the time it remains virulent, while social factors ma

Agricultural environments are critical to the conservation of biota throughout the world.

Consequently, there is a growing call from scientists around the world for the need to maximise the conservation value of agricultural environments. Efforts to identify key influences on the conservation status of fauna in agricultural landscapes have taken complementary approaches. Many studies have focussed on the role o

Abstract:

This research is an investigation into the phrase 'intermediate landscape' and tests this concept in the re-development of the Sanya waterfront, China. The phrase is based on the 'missing link' in the current disconnection between the landscape and urban development in Sanya city. If the landscape is considered as a connection across scales and urban systems rather than an isolated system, then how can landscape affect the structure and function of urban development? The 'intermediate landscape' considers the impact of understanding landscape not as an additional layer, but as a structure that

Lobaria pulmonaria is one of the species being affected by this habitat change, much due to their dispersal limitations, specific habitat demands and susceptibility to air pollution. 36 localities of two differ

Effective conservation requires an informed understanding of species' threats and capabilities, though it is unclear whether the increasing fragmentation of riparian woodland in western North America is affecting dispersal patterns of riparian bree

A high proportion of amphibian species are threatened with extinction globally, and habitat loss and degradation are the most frequently implicated causes. Rapid deforestation for the establishment of agricultural production is a primary driver of habitat loss in tropical zones where amphibian diversity is highest.

Decreased gene flow contributes to loss of genetic diversity, which limits the ability of local populations to respond to further env

The main prey groups replacing the lacking grouse were corvids, squirrels and hares. The proportion of grouse was highest in spring and it decreased towards the end of the nestling phase.
