Model development is of vital importance for understanding and management of ecological processes. Identifying the complex relationships between ecological patterns and processes is a crucial task. Ecological modelling—both qualitatively and quantitatively—plays a vital role in analysing ecological phenomena and for ecological theory. This textbook provides a unique overview of modelling approaches. Representing the state-of-the-art in modern ecology, it shows how to construct and work with various different model types. It introduces the background of each approach and its application in ecology. Differential equations, matrix approaches, individual-based models and many other relevant modelling techniques are explained and demonstrated with their use. The authors provide links to software tools and course materials. With chapters written by leading specialists, “Modelling Complex Ecological Dynamics” is an essential contribution to expand the qualification of students, teachers and scientists alike.
The book gives an account of political, social and economic changes in Namibia since independence in 1990.
Changes in land use and land cover can have many drivers, including population growth, urbanization, agriculture, demand for food, evolution of socio-economic structure, policy regulations, and climate variability. The impacts of these changes on water resources range from changes in water availability (due to changes in losses of water to evapotranspiration and recharge) to degradation of water quality (increased erosion, salinity, chemical loadings, and pathogens). The impacts are manifested through complex hydro-bio-geo-climate characteristics, which underscore the need for integrated scientific approaches to understand the impacts of landscape change on water resources. Several technique...
This book presents the results of the GMLS II conference on «Implications of GM-Crop Cultivation at Large Spatial Scales», held in Bremen in March 2010. The meeting was a platform to discuss ecological, agricultural and economic implications of genetically modified organisms (GMO) and to present new developments in risk assessment and monitoring. Approaches in co-existence regulations and nature protection standards are presented as well as legal challenges and resolutions on national and on EU-level. The book collects 30 contributions written by specialists in science, administration and jurisprudence from Europe as well as Africa, Central America, and Russia.
Originally presented as the author's thesis (Ph. D.)--Universiteat Bremen, 2008.
Individual-based models are an exciting and widely used new tool for ecology. These computational models allow scientists to explore the mechanisms through which population and ecosystem ecology arises from how individuals interact with each other and their environment. This book provides the first in-depth treatment of individual-based modeling and its use to develop theoretical understanding of how ecological systems work, an approach the authors call "individual-based ecology.? Grimm and Railsback start with a general primer on modeling: how to design models that are as simple as possible while still allowing specific problems to be solved, and how to move efficiently through a cycle of p...

The scale dependence of ecological processes and patterns, as well as their analysis is a long-standing theme in ecology. The problem of scaling has three components: (i) direct measurements are commonly limited to small scales in time and space, (ii) the most pressing problems have to be addressed at comparatively large scales, but (iii) direct upscaling fails when local processes differ from those relevant at larger scales. The contributions collected in this volume evolved from the workshop 'Multiple Scales in Ecology', held in March 2005 at Seddinger See near Potsdam in Germany. The book is organized along four major themes: scale-dependent pattern formation, scale identification, multiscale analysis, and scaling in applications.
This is a book about how ecologists can integrate remote sensing and GIS in their daily work. It will allow ecologists to get started with the application of remote sensing and to understand its potential and limitations. Using practical examples, the book covers all necessary steps from planning field campaigns to deriving ecologically relevant information through remote sensing and modelling of species distributions. All practical examples in this book rely on OpenSource software and freely available data sets. Quantum GIS (QGIS) is introduced for basic GIS data handling, and in-depth spatial analytics and statistics are conducted with the software packages R and GRASS. Readers will learn ...
By means of a discourse analysis in the tradition of Critical Linguistics this study traces and discusses anthropomorphism and anthropocentrism in the language used to describe our closest relatives, the monkeys and apes. As so-called 'boundary animals', the non-human primates have an impact on the way we regard humanity; they serve as model organisms for scenarios of human evolution. They thus inhabit a political space, where the definition of social structures, cognitive capacities, and human hallmarks such as culture and language is controversial. The National Geographic articles, which constitute the primary source of the analysis, allow not only a look at the picture of primates that is presented to the public but also an investigation of the changes this picture has undergone in the course of time. Are there different kinds of anthropomorphism and if so what are they aiming at? In becoming more human-like in our eyes, the apes have also become worthier of protection. However, there may be disagreement both on the nature of the ape and on the acceptability of parallels drawn with humans.
