Abstract:

Ecological models are central to understanding of hydrological and carbon cycles. These models need input from Earth Observation data to function at regional to global scales. Requirements of these models and the satellite missions designed to fulfill them are reviewed to asses the present situation. The aim is to establish a better informed framework for the design and development of future satellite missions to meet the needs of ecological modellers. Key land surface parameters that can potentially be derived by remote sensing are analysed - leaf area index, leaf chlorophyll content, the fra

The Development methodological principals for estimation of the economic damage has been leading since 60-h years of XX century by scientist from many institutes, including Ukrainian scientist from Kiev, Sumy, Odessa, Lugansk, Lvyv, Donetsk, etc. For this time was accumulated huge information base, allowing suitable for valuation of the damages from ecologically destructive activity. So economic damage from the natural ambience components quality deterioration (the ecologically-economic damage) can be a factor, which allows estimating the size of the ecological debt in the most precisions

Abstract:

Despite the debate about the definition and subject of ecology, it is actually undeniable that the scientific study of the distribution and abundance of organisms, together with their underlying processes, is among the main subjects of ecology . Therefore, counting animals, and understanding the mechanisms that drive occurrence and abundance over space and time, have been the focus of many studies in animal science. Since population size is one of the fundamental state variables in ecology, obtaining accurate information on population abundance is of primary importance for conserv

Abstract:

The decline of many altricial species in temperate areas on land managed for agriculture is thought to be linked to changes in summer food availability, impacting on chick survival. This study specifically investigates the impacts of livestock grazing on the breeding performance of an insectivorous species, the meadow pipit (<i>Anthus pratensis)</i>, through the assessment of chick diet. Using conventional methods, adults are found to feed chicks a wide range of prey taxa. The significance of this diversity is shown by improved chick growth, emphasising an important link between diet and chick

In order to better manage progress toward improved human welfare, governments and organizations around the world have begun to report on more comprehensive indicators of environmental, social, and economic conditions. The Genuine Progress Indicator (GPI) has proven useful as a measure of economic welfare by incorporating changes in environmental conditions, resource stocks, social capital, income distribution, and other non-marketed economic activity. Studies at the local scale have also found the GPI to be an effective tool for informing debate and stimulating questions about the natur

The study of biological diversity has seen a tremendous growth over the past few decades. Among the commonly used indices capturing both the richness and evenness of a community, the Berger-Parker index, which relates to the maximum proportion of all species, is particularly effective. However, when the number of individuals and species grows without bound this index changes, and it is important to develop statistical tools to measure this change. In this thesis, we introduce two estimators for this maximum: the multinomial maximum and the length of the longest increasing subsequence. In both

A importância do Cerrado é devido a sua diversidade biológica e alto grau de endemismo, e demanda uma maior compreensão das formas de interação entre seus componentes. Atualmente, encontramos parte de sua estrutura original modificada pelo intenso processo de urbanização e pelo aprimoramento das práticas de agricultura intensiva. Por isso, uma relevante ferramenta disponível para o estudo qualitativo deste bioma são as estimativas de conectividade funcional, que consiste em quanto o ambiente facilita ou impede o movimento de organismos e propágulos entre as manchas de recursos.

Abstract:

Seabirds are widely used as an indicator species to track important changes in ecosystems. The key data required for monitoring include (i) population trends (ii) status, including demographic properties such as age structure and reproductive performance. Most seabirds have no outward or easily identifiable marks to age individuals and there are currently no robust molecular methods for age estimation in birds. Instead, individuals must be marked by leg rings as chicks to establish known-age populations, which is a labour intensive and expensive process. Long-term monitoring of some population

Abstract:

This dissertation investigates the problem of uncertainty in complex ecological models. The term "complex" is used to convey both the common and scientific meanings. Increasingly, ecological models have become complex because they are more complicated; ecological models are generally multi-variate and multi-leveled in structure. Many ecological models are complex because they simulate the dynamics of complex systems. As a result, and as science moves from the modern/normal to postmodern/post-normal paradigm view of the world, the definition of uncertainty and the problem of uncertainty estimat

Abstract:

Traditional molecular ecology has focused on describing the historic processes that lead to contemporary patterns of diversity within populations, species and higher taxa. Molecular tools can also identify the origin of biological material and shed light on contemporary ecological processes of populations and individuals. This thesis is concerned with evaluating the efficacy of some of these latter nascent applications for diagnosing near real-time ecological information in marine mammals. The applications under investigation were (i) DNA-based methods to identify the prey of cetaceans and (ii

Abstract:

A fundamental goal in ecology is to identify the appropriate scales at which to observe trends in ecosystem behavior. Researchers often rely on intuition to choose a sampling scale, which if too large or too small potentially obscures the real system trends. A characteristic length scale (CLS) is a natural scale of a system at which the underlying deterministic dynamics are most clearly observed over stochasticity. The overarching aim of this research was to develop, examine and apply a robust technique to detect CLSs of real ecological systems. In this thesis, I first compared the robu
