Economics of Sustainable Resource Use
… externalities such as transmission and ecosystem interactions. The SDG 14 framework distinguishes weak and strong sustainability and reveals uneven progress across EU countries. In fisheries, ignoring within-stock heterogeneity biases optimal size selectivity and harvest timing. These …

Modeling economies and ecosystems in general equilibrium
… to simulate complex systems, an economy and an ecosystem. In an economic application, this work leverages a novel data revision scheme to integrate technological detail on electricity generation and pollution abatement into national accounts data in a traditional economic computed general …

Physical Drivers of the Spring Phytoplankton Bloom in the Subpolar North Atlantic Ocean
… consequences for the marine carbon cycle and ecosystems. There are currently several proposed mechanisms to explain the timing of this bloom. The conventional theory holds that the bloom begins when the ocean warms and the seasonal mixed layer shoals in the spring, decreasing the depth to …

Local Variation in the Chemical Defence of European Pine Sawfly (Neodiprion sertifer): Effects of Host Tree Chemistry and Social Environment
… sources for this variation helps to understand ecosystem interactions and, to make more accurate predictions of species distributions and local abundances. The European pine sawfly (Neodiprion sertifer) is an example of a chemically defending forest pest insect that sequesters resinous acids …

Ecosystem effects of a rock-lobster 'invasion': comparitive and modelling approaches
… Haliotis midae, and an already over-exploited ecosystem, the lobster âinvasionâ is assumed to have had serious consequences on the benthic community and associated fisheries. To investigate these effects, I used both empirical and modelling approaches. Based on field studies, I first analysed …
