| An annotated list of the free-living insect herbivores collected on the seedlings of five rainforest tree species of economic importance near Mabura Hill, Guyana, is presented. The host plants were Chlorocardium rodiei (Scomb.) (Lauraceae), Mora gonggrijpii (Kleinh.) Sandw. (Caesalpiniaceae), Eperua rubiginosa Miq. (Caesalpiniaceae), Pentaclethra macroloba (Willd.) Kuntze (Leguminosae,) and Catostemma fragrans Benth. (Bombacaceae). During the monitoring of approximately 10,000 seedlings at monthly intervals during two years, 27,735 insect individuals were collected representing 604 species. Leaf-chewing insects were further tested in captivity, to remove transient and non-feeding species. The most common higher taxa included Psyllidae, Cicadellinae,... |

| Each dipterocarp has its own species of fungus, forming an ectomycorrhiza. From literature and experiments (in East Kalimantan and in vitro) ecological consequences are explored. These help explain the clumping of dipterocarp trees in the forest, the lack of hybrids, the poor dispersal, and speciation as dependent on the viability of the root-fungus combination on a particular soil type. Mycorrhizas are located in the top soil. They are extremely sensitive to increase of soil temperatures as occur after canopy opening, and to soil compaction by machinery and log skidding. This explains the setback of dipterocarp growth after crude logging. It is suggested that avoidance of soil compaction during logging, quick restoration of soil cover, and the use of... |

| Hose’s leaf monkey Presbytis hosei is endemic to Borneo and occurs only in tall forest. In recent decades Borneo has lost a large part of its forest cover, mostly in low-lying coastal regions. Large intact tracts of forest remain in the interior, but these are by and large inhabited by tribes that subsist in part by hunting. The combined effects of habitat disturbance and hunting on the densities and biomass of Hose’s leaf monkey were studied in Kayan Mentarang National Park in Borneo’s far interior. Over four months, data on densities and hunting were collected by transect walks in four forest types. Hose’s leaf monkeys were hunted to deter crop-raiding, for their meat, and to obtain bezoar stones (visceral secretions used in traditional medicine). Hose’s... |
