Agent-based modelling is widely used in social and ecological sciences. For biological processes it is an increasingly used technology. Here we used agent-based modelling to simulate the formation of actin filaments, which is a major part in the cytoskeleton of the cell and plays a role in a number of cell functions. We present in this paper three models with different levels of detail and show...

Theory suggests that frequency-dependent resource competition will disproportionately impact the most common phenotypes in a population. The resulting disruptive selection forms the driving force behind evolutionary models of niche diversification, character release, ecological sexual dimorphism, resource polymorphism, and sympatric speciation. However, there is little empirical support for the...

To achieve an ‘ecosystems approach’ for marine resource management, we need to disentangle human impacts from natural variability, over a range of temporal and spatial scales. This Theme combines physical modelling and trophic dynamics to re-assess past changes in marine ecosystems and predict their future development. It includes consideration of the ecological impacts of renewable energy sche...

An integrated ecological-economic decision-making approach is developed to help local stakeholders decide on land use in rural areas where the conflict between natural resource protection and economic development is pressing. It consists of four methodological steps. In the first step the political options and alternatives for action regarding changes in the land-use pattern are specified in or...

Goal To analyze the possibility for recreational fishing to induce genetic changes in exploited fish populations, and thereby to increase awareness of such potential among stakeholders and stimulate increased research effort and long-term monitoring of fish populations exploited by angling fisheries. As a result of selective (i.e. non-random) mortality, exploitation of wild living resources can...

Remote sensing and geographic analysis of woody vegetation provide means of evaluating the distribution of natural resources, patterns of biodiversity and ecosystem structure, and socio-economic drivers of resource utilization. While these methods bring geographic datasets with global coverage into our day-to-day analytic spheres, many of the studies that rely on these strategies do not capital...

The advantages of distributing workloads and utilizing multiple distributed resources are now well established. The type and degree of heterogeneity of distributed resources is increasing, and thus determining how to distribute the workloads becomes increasingly difficult, in particular with respect to the selection of suitable resources. We formulate and investigate the resource selection prob...

Context Bennett’s wallaby (Notamacropus rufogriseus) was introduced into New Zealand in the late-1800s, and has subsequently become a significant pest to agriculture, silviculture, native vegetation. Effective management of wallabies requires robust spatial temporal ecological information, which can be used operationally increase detection kill rates.Aims To determine home range size shape, res...
