“…1) were present in two plots only, and the remaining 54 species were restricted to one of the plots. Importantly, the putative ectomycorrhizal tree species Pseudomonotes tropenbosii (Dipterocarpaceae) showed the highest Important Value Index (IVI) of 6 % in AR-PR (Londoño et al 1995). Cluster analysis of tree and fungal biodiversity yielded similar patterns (Fig.…”

“…They are loose and sandy at the surface and become clayey with depth. The vegetation corresponds to a mixed forest with a canopy height of 25-30 m (Londoño 2011;Londoño et al 1995). The plant species diversity is high with 700 species of vascular plants (i.e., herbs, ferns, shrubs, palms, lianas and vines) per hectare.…”

“…The plant species diversity is high with 700 species of vascular plants (i.e., herbs, ferns, shrubs, palms, lianas and vines) per hectare. Pseudomonotes tropenbosii Londoño et al, a putative ectomycorrhizal tree species belonging to the ectomycorrhizal tree family Dipterocarpaceae (Smits 1994;Tedersoo et al 2007), occurred here (Londoño et al 1995). In this dipterocarp forest a 1,000 m 2 permanent plot was established during the early 1990s by scientific explorations of Tropenbos Colombia researchers and was investigated here for macrofungal diversity and productivity.…”

Macrofungal diversity in Colombian Amazon forests varies with regions and regimes of disturbance

Here we present the results of fungal biodiversity studies from some selected Colombian Amazon forests in relationship to plant biodiversity and successional stages after slash and burn agriculture. Macrofungal diversity was found to differ between forests occurring in two regions (Araracuara vs Amacayacu) as well as between flooded forests and terra firme forests in the Amacayacu region. Macrofungal biodiversity differed between regeneration states of different age in the Araracuara region. Suitable substrates, especially dead wood that occurred as a result of recent slash and burn agriculture, resulted in the formation of many sporocarps of wood-inhabiting species. Putative ectomycorrhizal species were found in a dipterocarp forest. Fifty two percent of the macrofungal species could not be identified to the species level, but could be assigned to a genus, and it is likely that a significant portion of these represent species new to science. Long term studies are needed to obtain a comprehensive and complete understanding of the diversity and functioning of mycobiota in Amazon forest ecosystems.

“…In a wide sense, it includes three subfamilies: Dipterocarpoideae in Asia, Pakaraimoideae in South America and Monotoideae in Africa, Madagascar and South America (Maguire & Ashton 1977, Londoño et al 1995. However, the status of Pakaraimoideae and Monotoideae as subfamilies of the Dipterocarpaceae is a matter of discussion, and Kostermans (1985) argues that species belonging to these two subfamilies are closely allied to the Tiliaceae.…”

The diversity of Dipterocarpaceae in Angola is updated to 24 taxa, two species of Marquesia and 22 species and subspecies of Monotes. A new species is described and four new records (three species and one subspecies) are added to the Flora of Angola. The new species, Monotes paivae, occurs in the province of Bié, central Angola. Its diagnostic characters are a persistent indumentum on the entire upper surface of leaves and a woollytomentose indumentum in the lower surface of adult leaves. A key to the species and the respective descriptions is presented. The species of Monotes endemic in the country are mapped and their conservation status is discussed.Resumo A diversidade da família Dipterocarpaceae em Angola é actualizada para 24 taxa, duas espécies de Marquesia e 22 espécies e subespécies de Monotes. Uma nova espécie é descrita e quatro novos registos (três espécies e uma subespécie) são adicionados à flora de Angola. A nova espécie Monotes paivae, ocorre na províncias do Bié, no centro do país. É caracterizada por possuir indumento persistente em toda a página superior das folhas e um indumento lanoso-tomentoso na página inferior das folhas adultas. Apresenta-se uma chave das espécies e a respectiva descrição. As espécies de Monotes endémicas em Angola são cartografadas e o seu estatuto de conservação discutido.

“…Dipterocarpaceae form an important pantropical tree family comprising three subfamilies according to recent classifications (Ashton, 1982;Loñdono et al, 1995;Morton, 1995) with 'Dipterocarpoideae', 'Monotoideae' and the 'Pakaraimoideae'. Many tropical forests in Asia are dominated by dipterocarps (Dipterocarpoideae) and can be regarded as hot spots of global biological diversity (Cao et al, 2006).…”

The dipterocarps are of economic and ecological significance. To determine if simple traits can be used to distinguish wood of five representative species (Dipterocarpus kerrii, Hopea plagata, Parashorea malaanoman, Shorea almon and Shorea contorta), we determined tree height, wood density and chloroplastic (cp) DNA restriction patterns as a molecular fingerprint. Wood was obtained from trees of the same age grown at the same plantation (Leyte, Philippines). Data were subjected to cluster analysis (tree height, wood density) and used for the construction of a phylogenetic tree (cpDNA-PCR). Comparison of the result of cluster analysis with the phylogeny of the taxa based on cpDNA variation showed similar differentiation patterns. D. kerrii and H. plagata were always clearly separated from the other three species. Cluster analyses on tree characters revealed a clear grouping of all samples according to species, except for S. contorta, which was partly mixed with the subcluster of P. malaanoman. Since the formation of clades obtained by cpDNA-PCR analysis of samples was similar to that found by cluster analysis, our data indicate that wood traits can be used for taxonomic purposes to distinguish distantly related tree species of the same family.
