“…Tropical fungi seem to be generalists in terms of host tree species (Gibertoni et al. ) but not necessarily in terms of deadwood types (Urcelay & Robledo ). Wind conditions in dense tropical forests are likely to be very different from the more open boreal and temperate forests, which may hinder dispersal of airborne spores (Gilbert ).…”

“…Large reserves would also maintain genetic diversity; however, connectivity is rarely an issue in conservation of genetic diversity because very little long-distance dispersal is adequate to maintain genetic heterogeneity (Trakhtenbrot et al 2005). Finally, due to the restricted distribution of many tropical species (for saproxylics see Araujo et al 2015;Gibertoni et al 2015), connectivity of conservation areas may be less important for saproxylic species in the tropics than in the more homogeneous boreal and temperate regions.…”

Limited knowledge of dispersal for most organisms hampers effective connectivity conservation in fragmented landscapes. In forest ecosystems, deadwood-dependent organisms (i.e., saproxylics) are negatively affected by forest management and degradation globally. We reviewed empirically established dispersal ecology of saproxylic insects and fungi. We focused on direct studies (e.g., mark-recapture, radiotelemetry), field experiments, and population genetic analyses. We found 2 somewhat opposite results. Based on direct methods and experiments, dispersal is limited to within a few kilometers, whereas genetic studies showed little genetic structure over tens of kilometers, which indicates long-distance dispersal. The extent of direct dispersal studies and field experiments was small and thus these studies could not have detected long-distance dispersal. Particularly for fungi, more studies at management-relevant scales (1-10 km) are needed. Genetic researchers used outdated markers, investigated few loci, and faced the inherent difficulties of inferring dispersal from genetic population structure. Although there were systematic and species-specific differences in dispersal ability (fungi are better dispersers than insects), it seems that for both groups colonization and establishment, not dispersal per se, are limiting their occurrence at management-relevant scales. Because most studies were on forest landscapes in Europe, particularly the boreal region, more data are needed from nonforested landscapes in which fragmentation effects are likely to be more pronounced. Given the potential for long-distance dispersal and the logical necessity of habitat area being a more fundamental landscape attribute than the spatial arrangement of habitat patches (i.e., connectivity sensu strict), retaining high-quality deadwood habitat is more important for saproxylic insects and fungi than explicit connectivity conservation in many cases.

Polypores from an Atlantic rainforest area in Southeast Brazil: resupinate species). During a survey of polypores in the Parque Estadual da Cantareira, São Paulo State, Brazil, seventeen unusual and distinctive resupinate species previously unregistered were found and identified, increasing to eighteen the number of resupinate species known for this area. Morphological comments and an identification key are provided for all the species. Rigidoporus undatus and Trechispora regularis were recorded in São Paulo State for the first time, and full descriptions with illustrations are provided.
