Titre : Wood-inhabiting fungi in danish deciduous forests - diversity, habitat preferences and conservation Type de document : Électronique Auteurs : Jacob Heilmann-Clausen Année de publication : 2003 Importance : 54 p. Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Champignons Résumé : The present thesis is based on six manuscripts, which consider various aspects of conservation biology and ecology of wood-inhabiting fungi. Paper I provides an analysis of the role of focal species in conservation biology, based on the assertion that focus on particular species or species groups represents a relevant but often tendentious and subjective way of making conservation biology work in practice. It is argued that different focal species concepts express different, often implicit subsets of normative arguments for biodiversity conservation. On this basis the relevance of wood-inhabiting fungi as focal species is discussed, and it is stated that there are few “hard” arguments for the conservation of rare wood-inhabiting fungi in nature. Accordingly, conservation initiatives aiming on conserving woodinhabiting fungi are only relevant if based on ethical considerations appreciating nature and biodiversity to have intrinsic value. In this context wood-inhabiting fungi are interesting in several ways. They constitute a substantial part of forest biodiversity and play key roles for other organisms dependent on decaying wood. In addition the composition of wood-inhabiting fungal communities may reflect recent and past forest history, and there is some evidence that rich occurrences of particular species may point to high levels of dead wood and megatree continuity at the local to regional scale. The remaining papers investigate the ecology of wood-inhabiting fungi with special emphasis on habitat preferences. In paper II the effects of exudates from uncolonized beech wood and beech wood previously colonized by a number of early decay agents is investigated with respect to mycelial growth in a range of late stage decay fungi. These were found to show very different and specific responses depending on treatment, and it is concluded that different early decay agents influence occupied wood chemically in specific ways, and that they thereby have pronounced effects on subsequent community development. In papers III-VI the habitat preferences of wood-inhabiting fungi are investigated on naturally decaying wood in a number of near natural deciduous forests, based on sporocarps inventories. The studies show that very substantial changes occur in the fungal species composition during the decay process, but also other habitat factors, i.e. tree species, climatic conditions, death cause, forest history, as well as the original position of the dead wood in the tree are identified to have marked effects on the fungal species composition on individual decaying trees. Tree dimensions, on the other hand, were only found to influence species composition to a limited extend, and it is suggested that tree death cause and the presence of certain early decay agents, which may depend on the presence of old trees, is more important to fungal diversity than tree size per se. Thus, certain heart rot agents seem to facilitate the development of decay communities supporting rare and red-listed successor species. The results are discussed in a conservation context. It is concluded that forests managed for timber production may support rich communities of wood-inhabiting fungi, if appropriate, but economically reasonable, measures are taken to increase dead wood levels. However, due to the highly skewed selection of dead wood habitat types present in managed forests (abundance of cut stumps and branches, scarcity of old-grown, natural dead trees) they are unable to protect all aspect of fungal diversity depending on dead wood.
