Abstract:

The declines of fish populations in ecosystems around the globe have triggered considerable interest in marine ecosystem restoration. In addition to focusing on individual fish populations, there is increased emphasis on understanding inter-species interactions and on understanding the human relationships with the ecosystems. My thesis approaches marine restoration from (a) practical aspects of considering multispecies interactions in the ecosystem (Ecopath with Ecosim models), estimating unreported and illegal catches (influence tables) and policy that considers the concerns of multiple stake

Abstract:

Experimental studies, in temperate grasslands, assessing the role of biodiversity and its effects on ecosystem functioning have generally shown that a decline in species number has negative effects on ecosystem functioning. Even though, this relationship has been intensively studied in the last ten years, little is known about it in complex and hyperdiverse tropical ecosystems and where species diversity is not manipulated. My research examines the relationship between biodiversity and ecosystem functioning in natural tropical forests with a special focus on scale. This research centers on fi

The rapid and ubiquitous spread of information technologies (IT) is creating unprecedented effects that challenge traditional fundamentals of the business world.

A platform-mediated ecosystem can be defined broadly as an industrial architecture with an infrastructure in the center that facilitates value co

However, in the academic research, it is addressed by a number of researchers that there is significant lack of empirical studies that examines the emergence and formation of business ecosystem, espe

Abstract:

One of the greatest challenges for sustaining the ecosystem services that we, as a society, derive from marine ecosystems is to minimize the knowledge gap relating to marine ecosystem values. That is, identifying, eliciting and understanding the economic value of the ecosystem services that marine systems provide for societies world-wide is key to ensuring sustainable resource use and environmental management of these ecosystems. This is particularly problematic for the ecosystem services derived from the deep sea as a tremendous knowledge gap exists for the many marine ecosystems that compris

Abstract:

This thesis investigates processes of ecosystem emergence. Ecosystem research has thus far focused on understanding the structure and dynamics of already existing ecosystems. However much less attention has been devoted to the emergence of ecosystems. I first theoretically develop an institutional approach to ecosystems, arguing that the ecosystem is an organisational field which has value co-creation as its recognised area of institutional life. Synthesising the theories of dominant design, social movements, and institutional entrepreneurship, I identify four activities that drive the process

Biodiversity loss is one of the major threats to humanity. This has led to an increasing amount of research on biodiversity on genetic and species levels.

Properties explaining the topological structure of food webs can be used to compare and highlight differences between ecosystems. In the present study, topological network properties are used to compare the diversity of network structures between groups of empiri

Abstract:

The main topic of this thesis concerns the study of how conflicting interests of software agents within an information ecosystem may cause cooperative behavior. Since such agents act on the behalf of their human owners, which often act in their own interest, this will sometimes result in malignant acts. Different types of models, often inspired by biological theories such as natural selection, will be used to describe various aspects of such information ecosystems. We begin by adopting a game theoretic approach where a generous and greedy model is introduced. Different agent strategies for ite

In population ecology models, fewer species are studied but greater detail of species interactions can be incorporated.
