Rovero","doi":"10.2982/028.104.0103","DOIUrl":"https://doi.org/10.2982/028.104.0103","url":null,"abstract":"Jonathan Kingdon, born in Tanzania in 1935 of English parents (his mother was a professional artist and teacher, and his father was then serving the British protectorate as a District Commissioner), is one of the foremost authorities on the study of the diversity and evolution of African mammals. He is also an extraordinary artist, most known for his illustrations of animals that have been placed firmly within the tradition of anatomical drawing finding its origins in Leonardo da Vinci. I have had the privilege of working with Jonathan over the past decade, and I am honoured to offer a tribute to his unparalleled work. I will primarily focus on Kingdon as an extraordinary scientist and illustrator of African mammals, the reach of his message as a source of inspiration and learning for generations, and his ultimate and pervasive call for the wisdom of modern societies to protect and maintain such incredible diversity of species against the alarming risk of extinction. He often brings up a very compelling and yet philosophical reason for this call, among the several others that would be equally well justified: “We became human in a very specific setting—within rich communities of African animals and plants. To destroy these communities is to detach ourselves, irrevocably, from our biological, even our intellectual past. To drift, senseless of our origins, is to impoverish science and medicine, to mythologise and trivialise our culture and to diminish us as descendants of countless generations of intelligent African mammals.” 2 The essence and significance of Kingdon’s work as a zoologist and evolutionary biologist stands, in my view, on two complementary sides of his investigation: the unprecedented production of a progressively augmented portrait of the diversity of African mammals, where each of the over 1100 species finds a space in the grand scheme, and the theoretical, synthetic research into the patterns of evolution of this extraordinary diversity that happened uniquely in Africa. This blend of scientific production, and its diffusion to the general public through several books, among which are the beautifully illustrated field guides to African mammals, is indeed without peer. It first entered the public domain with the seven volumes","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123213543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114413885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129574963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116215295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
