   Abstract : Using data from long-term studies of the vegetation in two areas under primary succession, patterns of colonisation and the accumulated seed bank during plant succession were studied.At century-old small islands in Lake Hjälmaren, Sweden, the genetic structure of differently old populations of Moehringia trinervia and Lythrum salicaria was studied, using allozyme variation for M.

   Abstract : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

   Abstract : Industry is a key player in the transition to a sustainable society, where manufacturing companies need to respond to the challenges of environmental concerns in several ways. The need for managing environmental technological change in production systems is and will continue to be a challenge for manufacturing companies, as they often tend to focus on short-term priorities to stay economically competitive, rather than developing the organisation to manage longer-term environmental competitiveness.
