- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Journal article (peer-reviewed)abstract
- Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - ). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

Attempts to Bridge the Gaps : Opportunities and Challenges in the Communicative Constitution of Organizations
- 2015

Doctoral thesis (other academic/artistic)abstract
- Globalization and technological advancements continue to challenge contemporary organizations’ aims to balance stability and change. As a response to this challenge, organizations often turn to empowerment and participatory processes. Current research emphasizes the need for enhanced communication in these processes. However, there is a lack of research studying how organizations practically enact this idea that these processes require more communication.This dissertation is aligned with the Montreal School’s CCO perspective and departs from communication theory seen as a dialogic of conversation and text, thus directing attention to coorientation and how organizational members coordinate in organizing processes. Based on this theoretical framework, the study aims to contribute to a better understanding – empirically as well as analytically – about the variety of texts that are a part of communicative initiatives aiming at enhancing communication, encouraging participation and empowerment processes.The empirical material is based on how two organizations explicitly emphasized communicative initiatives throughout each organization’s empowerment process attempts. One organization mainly used workshops to provide opportunities for communication, while the other organization incorporated an interactive video website for the same purpose.This dissertation acknowledges that managers and subordinates are not equally capable of discursively constructing the organization. However, enhanced communication through empowering processes has been shown to facilitate members’ abilities to contribute to the organizing process. Hence, the study combines two theoretical frameworks, the empowerment process model and the Montreal School’s CCO perspective, extending both and thereby accentuating the communication-power relationship.To further explore how conversations and text interact in the case organizations, the study enacts a tension-centered approach, arguing that tensions are produced, co- and reproduced and enacted through organizations’ wills to empower their members through communication. The findings indicate a recursive and reflexive relationship between the empowerment process, coorientation, tensions and participation. In practice, this means that organizational members who have the opportunity to engage in conversations about matters of concern while perceiving themselves as taking part in an empowerment process tend to more actively identify and co-produce tensions. Tensions increase participation and lead to new insights. As members realize the value of their input, this further enhances the empowerment process.
