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.

Two populations of Meruterrana elegans, a monotypic bush-cricket genus, endemic to Mount Kenya in Kenya were surveyed. The species is restricted to Cassipourea forest, a forest community vanishing rapidly on Mount Kenya and with it Meruterrana elegans, which therefore should be included to the IUCN red list of threatened species as Critically Endangered.

Comparative behavioural research reveals both intra- and inter-species diversity among primates. Few long-term behavioural studies have been conducted on African nocturnal primates. Here we describe and compare behavioural and ecological observations on two species of pottos (Perodicticus ibeanus and P. edwardsi) across ten sites. We observed a total of 51 P. edwardsi and 28 P. ibeanus. We recorded all 21 postures within an established lorisid ethogram, as well as 42 of 50 behaviours. Eating, locomotion, freezing, resting and sniffing were the most common behaviours. We recorded behaviours not previously described for perodicticines, including bark chewing and unique vocalisations. Three species of pottos are now recognised, with potentially more species to be revealed within this cryptic and nocturnal genus. Although there are similarities among potto species, we show that unique ecological adaptations and behaviours may further elucidate their diversity.
