Two new species of oribatid mites of the genus Pilizetes (Oribatida, Galumnidae) are described from litter and soil in the Korup National Park (Cameroon). Pilizetes paradudichi sp. nov. differs from Pilizetes dudichi Balogh, 1966 by the presence of long interlamellar setae and clearly longer notogastral setae. Pilizetes parasellnicki sp. nov. differs from Pilizetes sellnicki Balogh, 1958 by the presence of thickened, heavily ciliated and long epimeral setae 3b, 4a, 4b and 4c.

The relationship between mycorrhizal colonisation and phosphorus acquired by seedlings of the arbuscular mycorrhizal tree Oubanguia alata Bak f. (Scytopetalaceae) and the ectomycorrhizal tree Tetraberlinia moreliana Aubr. (Caesalpiniodeae) was evaluated at low and high inorganic phosphorus availability. AM colonisation was positively correlated with phosphorus uptake by O. alata at low, but not at high phosphorus availability. Seedlings growth was positively related to arbuscular mycorrhizal colonisation at both low and high phosphorus availability, suggesting that growth promotion by arbuscular mycorrhizas is not simply related to an increase of phosphorus uptake. In contrast, phosphorus uptake by T. moreliana was correlated with EM colonisation at both low and high phosphorus availability, but there was no relationship between growth and ectomycorrhizal colonisation. Promotion of phosphorus uptake by arbuscular mycorrhizas and ectomycorrhizas at low phosphorus availability is consistent with the co-occurrence of the two types of mycorrhiza in tropical rain forests where available soil phosphorus is low. However, ectomycorrhizal colonisation may also be of advantage where inputs of phosphorus rich litter raise the phosphorus status of the soil, as seen in the groves of ectomycorrhizal trees in Korup National Park, and may be one of the factors reinforcing local dominance by these trees.

Three new species of oribatid mites of the genus Pergalumna (Oribatida, Galumnidae) are described from litter and soil in the Korup National Park (Cameroon). Pergalumna jenoi sp. nov. differs from P. margaritata Mahunka, 1989 and P. pseudomargaritata Mahunka, 1994 by the presence of simple dorsosejugal suture, dentate anterior margin of the ventral plate, distinct reticulate pattern on the pteromorphs and dense stria on the genital plates, the localization of setal alveoli la posterior to porose areas Aa, and the absence of a median pore. Pergalumna tuberclesejugalis sp. nov. differs from P. margaritata and P. pseudomargaritata by the larger body size, the localization of porose areas Aa closer to lm than la, and setal alveoli h3 close and lateral to A2, the presence of sejugal porose areas, and the absence of a median pore and stria on the genital plates. Pergalumna grebennikovi sp. nov. differs from P. bifissurata Hammer, 1972 by the larger body size, the presence of smooth bothridial setae, well-developed interlamellar setae, reticulate anterior margin of pteromorphs, comparatively long prodorsal median ridge and a median pore, and the localization of setal alveoli la and porose areas Aa. An identification key to the known species of the genus Pergalumna from the Ethiopian region is presented.

A total of 390 bird species are known to occur in the Korup National Park (KNP) and the surrounding Korup Project Area (KPA). Although the avifauna of KNP is incompletely known, it is already among the most ornithologically diverse lowland forest sites i n Africa. The avian diversity of the KPA is increased by the montane forest bird species of the Rumpi Hills Forest Reserve (RHFR) and the Nta Ali Forest Reserve (NAFR). The lowland and montane forests of the KNP/KPA are very important to the conservation of African forest birds. Four species found in the Korup area are considered globally threatened, and four are considered near-threatened. In addition, 40 species were considered for threatened status, some of which are likely future additions to the threatened list. Twelve of Korup's 36 montane forest bird species are endemic to the montane areas of western Cameroon, eastern Nigeria, and Bioko (Fernando Po). The RHFR is especially important as a refuge for montane birds because much of the montane forest elsewhere in western Cameroon has been cleared for agriculture. Breeding phenology data are provided for many lowland forest species. Additionally, this report provides information on many rarely recorded species for western Cameroon, including several species not previously documented in the region. Kemp's Longbill Macrosphenus ketnpi was recorded for the first time in Cameroon. Because it is sympatric with the Yellow Longbill M. flavicans in Korup, additional evidence now exists for the contention that M. ketnpi and M.flavicans are separate species. The Yellow-chested Apalis Apalisflavidawas also documented for the first time in Cameroon.
