    ABSTRACT: An investigation to assess the relationship between coarse particulate organic matter (CPOM) and macroinvertebrate communities was undertaken in the Njoro River, Kenya during 2010. Significantly lower macroinvertebrate densities and diversities were observed in study sites with low Coarse Particulate Organic Matter (CPOM) content. The Mugo study site had the highest CPOM content and macroinvertebrate density and diversity. The unidentifiable detritus category (i.e. small CPOM fragments) had the highest influence on macroinvertebrate taxa whereas twigs had the least influence. The benthic samples were dominated by detritivores, but no shredders were recorded. Our results suggest that CPOM is an important determinant of the macroinvertebrate assemblages in streams. Given this, we believe that it is important to conserve tropical stream riparian vegetation due to their important role as a source of CPOM in streams.

    ABSTRACT: Mount Kasigau, the most northeastern mountain in the Eastern Arc, rises steeply from arid plains to a moist summit at 1641 m. This paper examines the diversity contributions of this afromontane setting by compiling a chorological analysis of tree species richness, measuring ecological differences among forest community types, and interpreting physical-environmental and human-historical factors that influence diversity patterns. Between 2002 and 2006, stem densities and basal areas of woody plants > 10 cm dbh were measured in 55 (0.1 ha) plots placed at different elevations. The study reports 140 species, 46 were measured in only one plot, and affinities for 75 species to the Somalia-Masai (43%), Afromontane (29%), and Zanzibar-Inhambane (Coastal, 28%) floristic regions. Cluster and Indicator Species Analyses identified eight community types. Mount Kasigau uniquely conserves much forest cover and a diversity of woody plant species below evergreen forest at 1000 m. Ordination, using Nonmetric Multidimensional Scaling (NMDS), resulted in a three-dimensional solution that explained 47.9% of the variation among plots. Axis 2 showed the strongest relationship with elevation (R2= 0.523), but lower montane community types also vary by slope form, slope aspect, and past human activities. We show how this biogeographical analysis of diversity patterns at Mount Kasigau can guide local management and support important opportunities for montane forest conservation in East Africa.

    ABSTRACT: This field guide represents a comprehensive treatment of the 184 woody plant species occurring in the Afromontane cloud forests of Taita Hills, Kenya. The first part contains an introduction to the Taita Hills and Eastern Arc Mountains, a list with endemic plant species, the multiple benefits the forests provide, additional references and a manual to use this guide. The second part contains identification keys that allow the reader to find the correct scientific name based on easy observable leaf characters rather than on more complex flower structures. The third part contains species fact sheets. These sheets are arranged alphabetically by their scientific names and include local vernacular names, diagnostic characteristics, (traditional) uses, photographs and illustrations. The last part contains a glossary of botanical terms and a species index.

    ABSTRACT: The sengis (elephant-shrews) of Mozambique are poorly known, especially the taxonomic status of the giant sengis, genus Rhynchocyon Currently, Rhynchocyon from Mozambique are thought to be chequered sengis, R. cirnei with specimens from the central coastal areas being placed in the subspecies R. c. cirnei, while the subspecific status of those from north-eastern areas has not been determined. To resolve this taxonomic ambiguity, we collected voucher specimens from north-eastern Mozambique. Based on a comparison of pelage patterns and colouration, features that are currently used to distinguish taxa in the genus Rhynchocyon, specimens from all of coastal Mozambique show minor variation, but are similar enough to indicate that they all are referable to R. c. cirnei.

    ABSTRACT: The new generic taxon Calyptomastix is proposed to accommodate the type species Odontopyge kakandae Kraus, 1958, and, tentatively, Odontopyge dorsalis Carl, 1909, Haplothysanus leviceps Attems, 1909, and Spirostreptus pardalis Gerstäcker, 1873, all from Tanzania. This genus is defined by the broad basal separation of the male genitalia, the elongated basal whorl (torsion) of the gonopod telopodite, and the concealment of the solenomere within apical folds of the telopodite.

    ABSTRACT: Recently rediscovered in the Udzungwa Mountains, Tanzania, with more distributional records from several central and southern Eastern Arc Mountains, the servaline genet Genetta servalina Pucheran, 1855 remains a rarely recorded species in East Africa. Using camera traps, we document several locations for G. servalina in and around the Amani Nature Reserve, East Usambara Mountains, Tanzania. These records extend the range of G. servalina to the northern part of the Eastern Arc Mountains.
