Resumen

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

Resumen

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. Platform-mediated ecosystems are increasingly attracting the attention of practitioners from diverse industries, from telecommunications to video consoles, as well as academics from different fields ranging from management to economics, and information systems (IS) and innovation management. A platform-mediated ecosystem can be defined broadly as an industrial architecture with an infrastructure in the center that facilitates value co

Resumen

Ecosystem-based management (EBM) is increasingly seen as the new paradigm for managing the use of marine resources and ecosystems. Although EBM has been defined in theory, its implementation has faced challenges worldwide. This research aims to examine two approaches to contribute to the operationzalization of EBM by incorporating stakeholder values in the decision-making process, and by better representing ecosystem dynamics in ecosystem models. First, I illustrate a decision-making framework for EBM rooted in structured decision-making (SDM), a well-known systematic approach for planning and

Resumen

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

Resumen

Ecosystem services are the benefits people obtain from ecosystems. Ecosystem service valuation (ESV) is the process of assessing the contributions of ecosystem services to human well-being. Its goal is to express the effects of changes in ecosystem services in terms of trade-offs against other things that also support human welfare. Ecologists tend to use biophysical-based methods while economists have developed preference-based tools for ESV. In this dissertation I attempt to bridge these two worlds by writing six papers using methods and insights from both disciplines. In paper 1, my coautho

Synthesising the theories of dominant design, social movements, and institutional entrepreneurship, I identify four activities that drive the process

In Ukraine, the largest user of natural resources is the agricultural complex. About 60% of the country's lands are used for agricultural purposes. During the years of independence, the system of land use in agriculture has completely changed. Emergence of a large number of owners and lessees of farmland increases the range of stakeholders in Agriculture and Natural Resources. New land users, in most cases, have no agronomic knowledge and take land and agro-ecosystems as a source of quick profits. Farmland cannot be considered only as an economic object, place to work and receive products or

This thesis assessed the current prospect for implementing an ecosystem-based management for fisheries (EBFM) in the Bay of Bengal Large Marine Ecosystem from national and regional level perspectives. A central result of the study is that the governance concept had been defined and used imprecisely in the literature. The way the different elements constitute EBFM revealed that both Bay of Bengal LME countries and existing regional fisheries organisations are unlikely to satisfy all the elements on the EBM checklist.

Resumen

Sea otters are nearshore predators whose impacts have potential implications for the provision of ecosystem services on the west coast of Vancouver Island. Sea otter predation on herbivorous sea urchins can allow kelp beds to flourish. Increased kelp production can act as a food subsidy to mussels which can promote faster growth. Otters also depredate mussels, which can affect the habitat provision function of mussels and limit them to sizes that are vulnerable to other predators. In this thesis I describe two empirical studies that explore these possible effects of otters on ecosystem process

Freshwater swamp forests are wetland ecosystems of global importance, especially because they provide very valuable ecosystem services such as regulation of flood and maintenance of water quality, and provide suitable habitat for the conservation of wetland ecosystems (flora and fauna).
