This paper describes Work Domain Analysis (WDA) applied to the domain of automated midair collision detection and avoidance as a first step in the design of improved ecological interfaces for automated traffic alerting displays. Three abstraction hierarchies (AH) modelling the aircraft, collision environment, and a traffic alerting system are presented, and the challenges of adapting the AH to ...

The incorporation of ecological objectives in the design of information systems has gained increasing attention by IS research in recent years. Nevertheless, from the perspective of IT Service Management (ITSM), comprehensive approaches are still warranting attention. The objective of this paper is therefore to develop a process for the management of ecology in ITSM. By using the method of refe...

Macroalgae is a biological key element for the assessment of the ecological status in coastal waters in the frame of the European Water Framework Directive (WFD, 2000/60/EC). Here we propose a methodology for monitoring water quality based on the cartography of littoral and upper-sublittoral rocky-shore communities (CARLIT, in short). With the use of spatial databases, GIS, and available inform...

Fabaceae species play a key role in ecosystem functioning through their capacity to fix atmospheric nitrogen via their symbiosis with Rhizobium bacteria. To increase benefits of using Fabaceae in agricultural systems, it is necessary to find ways to evaluate species or genotypes having potential adaptations to sub-optimal growth conditions. We evaluated the relevance of phylogenetic distance, a...

Why non-breeding subordinates of many animal societies tolerate group-living remains a pertinent question in evolutionary biology. The ecological constraints and benefits of philopatry hypotheses have the potential to explain the maintenance of group-living by specifying the ecological conditions favouring delayed dispersal over independent breeding by subordinates. In this study, I used field ...

The dnaA region of Wolbachia, an intracellular bacterial parasite of insects, is unique. A glnA cognate was found upstream of the dnaA gene, while neither of the two open reading frames detected downstream of dnaA has any homologue in the database. This unusual gene arrangement may reflect requirements associated with the unique ecological niche this agent occupies.

This paper presents the development up to date of a computer framework for integrating LCE methods and tools aimed at supporting ecological and economical decision making of product chains in a collaborative way. In particular, this paper proposes an approach to assist engineers and other decision makers in finding models that can be assembled into combined process that satisfy the product requ...

Knowledge of the ecological requirements determining tree species distributions is a precondition for sustainable forest management. At present, the abiotic requirements and the relative importance of the different abiotic factors are still unclear for many temperate tree species. We therefore investigated the relative importance of climatic and edaphic factors for the abundance of 12 temperate...
