Saproxylic insects are characterised by their exceptional diversity and high proportion of threatened species. No recent studies have demonstrated the validity of habitat suitability analysis for scientifically based habitat management for these species. We studied the habitat requirements of the endangered longhorn beetle Cerambyx cerdo, a species with a supposed keystone function for the sapr...

The integration of conservation area designs for aquatic and terrestrial species has been a challenge for planners. The difficulties of crafting a single suitability index which reflects the landscape condition relative to all species, terrestrial and aquatic, and choosing assessment units appropriate for both realms, have made integration especially problematic. Here I will introduce a new tec...

Modelling is an effective tool to investigate the ecological state of water resources. In developing countries, the impact of sanitation infrastructures (e.g. wastewater treatment plants) is typically assessed considering the achievement of legal physicochemical quality standards, but ignoring the ecological water quality (EWQ) of the receiving river. In this paper, we developed a generic integ...

We describe a progression fiom pilot studies to development and use of domain-spec fzc verification and validation (V& v ) automation. Our domain is the testing of an AIplanning system that forms a key component of an autonomous spacecraft. We used pilot studies to ascertain opportunities for, and suitability OJ; automating various analyses whose results would contribute to V& V in our domain. ...

Themain idea behind social participatory sensing is to leverage social friends to participate in mobile sensing tasks. A main challenge, however, is the identification and recruitment of sufficient number of well-suited participants. This becomes especially more challenging for large-scale online social networks with unknown network topology and complex friendship relations. Moreover, the poten...

The identification of the suitable areas for common oat (Avena sativa L.) and naked oat (Avena nuda L.) in China using Multi-Criteria Evaluation (MCE) approach based on GIS is presented in the current article. Climate, topography, soil, land use and oat variety databases were created. Relevant criteria, suitability levels and their weights for each factor were defined. Then the criteria maps we...

Prioritizing areas for management of non-native invasive plants is critical, as invasive plants can negatively impact plant community structure. Extensive and multi-jurisdictional inventories are essential to prioritize actions aimed at mitigating the impact of invasions and changes in disturbance regimes. However, previous work devoted little effort to devising sampling methods sufficient to a...
