Agronomists and ecologists need each other and can learn from each other: agriculture cannot ignore ecological facts, neither can ecology study and conserve ecosystems without understanding contemporary agriculture. With this intention a symposium was organized on -the ecological implications of contemporary agriculture-. Five major groups of problems were discussed, related to major elements of the system, each corresponding to a session of the symposium:
- the soil and its life; - the plants, especially the unwanted ones; - the fauna, with emphasis on the control of pests;

This type of exercise of review and analysis for one component (carbon) of a relatively simple forest type is more generally useful in focusing thought and perhaps field research; critical knowledge gaps identified for pines presumably also apply to more complex forest ecosystems. This volume also serves to illustrate the value of comparative field studies, which in this case were totally unplanned and retrospective.

The scope of this volume is intentionally broad. We review applications of spatially realistic occupancy models and age- or stage-structured demographic models as well as individual-based demographic models. These three main Population Viability Analysis (PVA) approaches initially are compared with other conservation assessment tools in an overview by Akcakaya, Lacy and Sjogren-Gulve and Hanski, with a special chapter on plant PVAs by Menges, all using illustrative examples. Fleishman et al. subsequently outline how nested subsets analyses can help discern focal species, taxa whose habitat...

Maintaining forest biodiversity by combining protection, management and restoration of forest and woodland landscapes is a central component of sustainable development.
Evidence that there are threshold levels for how much habitat loss may be tolerated for viable populations of specialised species to be maintained.
Policy-makers, businesses and managers pose questions about how to balance use of renewable forest resources and conserve biodiversity.
Examples are presented on how biodiversity assessments can be made.
Proposes how the critical gaps in...

After 23 formative and producive years as Director of the Abisko Scientific Research Station, Mats Sonesson will retire from his duties. To honour Mats, to celebrate his career, and to thank him for all that he has done to enhance our research, we have asked those scientists who have worked at Abisko within the subject areas closest to Mats' interests, to contribute to this Festschrift which overviews the ecology and environment of the Tornetrask region. Twenty-three chapters written by 41 scientists from 10 countries have been contributed.
