Title Visualising bipartite networks and calculating some ecological indices. Description Bipartite provides functions to viualise webs and calculate a series of indices commonly used to describe pattern in ecological webs. It focusses on webs consisting of only two trophic levels, e.g. pollination webs or predator-prey-webs. Visualisation is important to get an idea of what we are actually loo...

We gathered information on the functional traits of the most representative copepod species in the Mediterranean Sea. Our database includes 191 species described by 7 traits encompassing diverse ecological functions: minimal and maximal body length, trophic group, feeding type, spawning strategy, diel vertical migration and vertical habitat. Cluster analysis in the functional trait space reveal...

As the oldest species of Betulaceae, Nepalese alder (Alnus nepalensis) shows a high capacity for nitrogen fixation, rapid growth rate, and strong adaptability to stress environments, it plays an important role in maintaining structure function forest agroforestry ecosystems. We explored its geographic distribution corresponding environmental drivers through collecting specimen records published...

The paper explores the development of ecological sanitation (EcoSan) within the small-town context of Lichinga, Niassa Province, Mozambique. The paper looks at how ESTAMOS (a Mozambican NGO) and WaterAid introduced EcoSan in Lichinga, how families and communities have responded to EcoSan, and key lessons learned during the process to date that could be relevant to others within and beyond Mozam...

When comparing the average citation impact of research groups, universities and countries, field normalisation reduces the influence of discipline and time. Confidence intervals for these indicators can help with attempts to infer whether differences between sets of publications are due to chance factors. Although both bootstrapping and formulae have been proposed for these, their accuracy is u...

The intention of this paper is to propose interaction design as a venue for IS research into sustainability and in that connection also propose a new theoretical psychological approach to interaction design. This new theoretical psychological framework is based on ecological psychology and activity theory. The paper will outline the scientific demands for the framework as well as the frameworks...

The operating theatre is a noisy place with many uninformative and redundant alarms. Using data from a recent observational study, we demonstrate that anaesthetists actively respond to only 3.4% of all audible alarms. We outline a range of possible solutions to the alarm problem. Ecological Interface Design (EID) helps to outline the requirements for an information environment for anaesthetists...

In this chapter we outline an ecological approach to computer games and test out how the theory of ecological psychology can be used for understanding digital games and game-play. Ecological psychology holds that learning is a process of differentiating and not of interpreting or construing. Therefore semiotic/cognitive views on learning and perception with computer games, were the perceptual a...

The GERRI project materializes the Grenelle Environnement’s goals, of which the energy management of a territory is a facet. The aim is to forecast future energy production and consumption, bearing in mind economic and ecological indicators, and using a large number of interactions schemes between the involved parties. The originality of this paper is to present a new approach using the multi-a...
