Dept. Animal Ecology, Lund, Sweden
Positions and projects:
- During the years 1972 to 1980 I completed my Ph.D. project
on the ecology of the Hooded Crow (Corvus cornix) at the
University of Lund under the supervision of Sam Erlinge.
This work describes the ecology of a crow population by means
of wing tagged birds. I tried to understand factors that
affect the behaviour and performance of different individuals.
Some experimental studies of breeding performance were also included.
During the latter part of this period I was employed by the project
"Impact of predation on field game populations" (financed by the
National Environmental Protection Board, SNV).
- After my examination I worked for two years (1980 to
with theoretical analyses of predator - prey interactions in general and,
in particular, in the vertebrate community of the Revinge area,
studied by a work group at the ecology department in Lund.
My work was supported by the projects "The Application of Theoretical
Models to Nature Conservancy" (SNV) and "Regulating Mechanisms in
a System of Vertebrate Predators and their Prey" (financed by
Swedish Natural Science Research Council, NFR).
The main task was to simulate different predator - prey systems.
Thus I tested whether the mechanisms included in the simulated
models could possibly explain the behaviour of the real
system previously studied.
- From 1982 to 1985 I worked with the project
"The Vertebrate Fauna in the Agricultural Landscape" (SNV)
(from 1983 as project leader). In this project I analysed the
distribution of vertebrate populations from a landscape ecology
perspective. Which is the effect of patch size and isolation on
population density and species richness? Taxa considered were birds,
small mammals and, to some extent, frogs.
- In December 1983 I also worked as "scientist" for National Museums
of Kenya in the Kora research project. I contributed to an
inventory of amphibians and reptiles and conducted a study
of Agama social ecology.
- From 1985 to 1988 I was employed by and led the project
"Seed Predation as a Limiting Factor for Plants in the
Agricultural Landscape" (SNV). This project was largely concerned
with the same issues as the preceding SNV-project. However,
small mammals and seed predation was in the focus. The central
question studied was whether seed predation is of similar importance
in small and large habitat islands.
- From 1988 to 1994 I was employed as "scientist" in
"Zooecology, specially Fauna Conservation and Landscape Ecology in
Agricultural Landscapes" by Swedish Council for Forestry and Agricultural
Research (SJFR). My work was financed by the project "Habitat Fragmentation
as a Limiting Factor for the Fauna in Agricultural Landscapes"
and "Microevolution of the common frog in an agricultural
landscape" (also SJFR).
Within this project I have concluded some work that was started as part
of the previous project. The work was however been concentrated on a
study of common frog species (Common Frog (Rana temporaria), Moorfrog
(Rana arvalis), and Common Toad (Bufo bufo)) in the agricultural landscape.
Some work on amphibians and reptiles has been carried out on a restricted
time schedule concurrent with my earlier projects but it came now in
the focus. The main goal was to determine what factors limit the
distribution of these migratory species in a highly fragmented landscape.
Included are descriptive studies of migratory behaviour and breeding sites
in this landscape. I have also started field experiments to reveal if
frogs are density regulated during the tadpole stage and conducted
studies of the importance of pond drying for development and growth rate.
- As a side interest I have conducted some short studies on the
social ecology of lizards in cooperation with other reseachers.
These include studies on the Rainbow lizard (Agama agama), the Hardun
(Agama stellio), and the Common Chameleon (Chameaeleo chamaeleon).
- 1994 to 2002 employed as lecturer by the University in Lund.
Part of my duties at the University included supervision of the
Animal Ecology department's computers.
- Since 2002 owner and sole employed by the consulting
company Rana Konsult
- 2002-2005 employed as scientist by the University of Lund.
My research was financed by the project "Landscape ecology and pond quality.
Field experimental studies of frogs in an agricultural landscape" (FORMAS).
I have supervised two Ph.D. students (Thomas Madsen and Björn Lardner), one
Masters (Fil lic.) student (Ralph Tramontano) and eight "D-kurs"/examination
I have been the faculty opponent at the doctoral dissertation of Per Sjögren,
Uppsala 1988 and the licentiate dissertation of Lena Berg, Uppsala 1997. I have been external
examiner for the thesis of Steven Melvin, New Brunnswick, Canada 2012.
I have been evaluator for a position as "Forskarassistent" at Grimsö Game Biology Research station 1995.
I have been evaluator for a research grant application to "Natural Environment Research Council", U.K., 2001.
I have been an "International Reader" for the Australian Research Council (2005-2006).
I have been referee for the Austrian Science Fund 2011.
I have served as referee for articles submitted to Acta Zoologica Fennica; Acta
Zoologica Sinica; Agriculture, Ecosystems & Environment; Alytes; American
Naturalist; Amphibia - Reptilia; Animal Behaviour; Ardeola; The Auk; Biological
Journal of the Linnean Society; Behavioral Ecology; Biodiversity and

I have served one 3y term as "Subject matter editor" of Ecology (2004-2006).
I have been a member of the board of ISSCA (International Society for the Study
and Conservation of Amphibians) 1994-2004. I have been president of ISSCA 2006-2011.
