ABSTRACT Small mammals were sampled in Ruaha National Park in 2011. Forty-three species of small mammals (three species of Soricomorpha, 23 species of Chiroptera, 17 species of Rodentia) were documented. An additional three species of bat were documented from specimens found independently of this survey. Identifications and natural history data are presented for each of the species encountered. Particular attention was paid to the Isunkaviola Plateau, a forest habitat at higher altitudes within the Park, which had no previous study of small mammals. The fauna of Isunkaviola Plateau bears little resemblance to that of the Eastern Arc Mountains or the Southern Highlands.

Jonathan Kingdon is recognised for his profound knowledge of natural history and his meticulous and superb drawings of African mammals. These two strengths come together in the study of mammalian colouration where his colour paintings and his black and white drawings depict the patterning of coat colours exceptionally well. Sometimes the underlying morphology and the way that animals show off their pelage patterns are shown too. While artwork is central to Kingdon’s career, resulting in the field guides for which he is so renowned, he has also offered multiple hypotheses regarding the evolutionary history and selective forces underlying colouration in mammals. Some of these hypotheses have been tested and confirmed, others have directed research in new directions, as I show below. Kingdon has long been a champion of functional ideas about mammalian colouration. One of his most memorable findings concerns the crested or maned rat Lophiomys imhausi MilneEdwards 1867 (figure 1). This species has woolly grey fur, bold black and white markings on the face, and black and white lateral stripes. When alarmed, fur on the flank is flared to reveal a tract of specialized hairs that the animal presents to its attacker. Crested

ABSTRACT In comparison to other ecosystems in east Africa, the biodiversity of the coastal forests of Kenya's northern coastline is poorly documented, even in the case of large terrestrial mammals. In response to this, we undertook a systematic survey of the Boni-Dodori forests using four camera trap grids with camera spacing of 2 km covering 300 km2 over 7020 camera trap days. We recorded 37 mammal species and derived camera trap rates and estimated occupancy for 31 medium-to-large terrestrial species, some of which represent range extensions. Remarkably, the critically endangered Aders' duiker was the most frequently recorded species. A distinctive form of giant sengi and the vulnerable Sokoke bushy-tailed mongoose were also widely distributed and relatively abundant. Other significant records of threatened species included African wild dog, African lion and Pousargues's monkey. Species richness and relative abundance of all species were higher than that recorded for Arabuko-Sokoke Forest, Kenya's only other large coastal forest, using the same camera trap survey protocol.

ABSTRACT Maned rat Lophiomys imhausi is a highly unusual, but very little known rodent that is endemic to East Africa. A population from the highlands of central Kenya was studied through analysis of owl pellets and prey remains, including one incidental observation. Over 28 months, 40 individual rats were documented, of which two were juveniles. The mean length of time between discovery of rat remains in any one owl territory was once every 5.3 months, and the maximum number of rats found in any single owl territory over one year was five. Maned rat density was low and was estimated at 1 rat/km2. Their lower altitudinal limit in Kenya is c. 1900 m, and eagle owls and humans are important predators. Maned rats are not uncommon in highly altered habitats and they may require poisonous plants in addition to Acokanthera spp. for anti-predator defense.

ABSTRACT Kakamega Forest is a small remnant of Guineo-Congolian rainforest in Kenya. Along with direct observation, we used an automatic camera to sample the nocturnal and crepuscular mammalian fauna within 1.5 km of the Kakamega Forest Station near Isecheno. We detected 11 indigenous species belonging to 10 genera, as well as domestic cats and dogs. We directly observed pottos and African palm civets. Additionally, we photographed giant pouched rats, African civets, white-tailed mongooses, a marsh mongoose, a tree pangolin, servaline genets, blotched genets, side-striped jackals, and what appears to be an African wildcat. We found both whitetailed and black-tailed morphs of the white-tailed mongooses. Similarly, we recorded side-striped jackals with and without white-tipped tails. Our findings offer insight about the seldom studied nocturnal and crepuscular mammals of Kakamega Forest, including which species are persisting there, their various morphs, and some bait preferences, thus adding to and reaffirming previous reports.

On 20 April 2017 in Edinburgh, Scotland, Africa lost one of its foremost botanists and University teachers of botany after a brief illness. Brian James Harris was born on 27 August 1929 in Neath, South Wales. By 1949 he had obtained his BSc in Agricultural Botany from the University College of Wales, Aberystwyth and in 1953, he earned a PhD from the University of Wales. Soon after obtaining his PhD, he was appointed as a Lecturer in the Botany Department of the University of Ghana (at the time the University College of the Gold Coast.) and continued in that post until 1965. From 1965 he was appointed Reader in Botany and Head of Department, University of Dar es Salaam. Brian developed an interest in field courses for students, and was a firm believer in the importance of students knowing how to identify plants and how to prepare and use herbarium specimens for research.
