Dans Biological Conservation (172 APR 2014)

Abandoned management of wooded grasslands leads to development of secondary woodland. We investigated how this development affects the colonization-extinction dynamics and persistence of epiphytic lichens associated with old trees. We modelled c[...]

Epiphyte metapopulation persistence after drastic habitat decline and low tree regeneration: time-lags and effects of conservation actions

Victor Johansson, Auteur ; Thomas Ranius, Auteur ; Tord Snall, Auteur

Dans Journal of Applied Ecology (50(2) APR 2013)

Old trees have declined in Europe due to agricultural intensification and forestry. For shade-intolerant epiphytic species occurring on old trees in semi-open landscapes, host tree numbers have further decreased because of shading by developing [...]
