Multiscale Perspectives of Species Richness in East Africa
Chapter 2 Chapter 2 Analysis of the relation between ungulate species richness in East Africa and climatic and remotely sensed productivity indices Mohammed Y Said1,2,∗, Andrew K Skidmore2, Jan de Leeuw2, Hesbon M Aligula1 Lalit Kumar 2 and Herbert H T Prins3 1Department of Resource Surveys and Remote Sensing (DRSRS), P.O. Box 47146 Nairobi, Kenya 2International Institute for Geo-information Science and Earth Observation (ITC), P.O. Box 6, 7500 AA Enschede, The Netherlands 3Tropical Nature Conservation and Vertebrate Ecology Group, Wageningen University, Bornsesteeg 69, 6708 PD Wageningen, The Netherlands Abstract The aim of the study was to evaluate whether climatic or remotely sensed indices are a better predictor of ungulate species richness. Our hypothesis is that the remotely sensed index the normalized difference vegetation index (NDVI) integrates the influence of climatic and environmental factors, it should be a better predictor of species richness than climatic variables. The study was conducted in East Africa, which has high ungulate species diversity. Out of 95 ungulate species found in Africa, 55 are found within this sub-region. The vegetation is highly heterogeneous, with great variability in productivity that is influenced by the spatial and seasonal distribution of climatic variables, including precipitation and temperature. Species richness was regressed against each environmental variable, using linear, polynomial, logarithmic and exponential models. A test of the equality of two population regression coefficients was used to compare the models. The results show that the strongest correlates of species richness were rainfall and NDVI, with 69% and 55% of the variance explained. A unimodal pattern was exhibited for ungulate species richness with both rainfall and NDVI. -
Beatragus Hunteri) in Arawale National Reserve, Northeastern, Kenya
The population size, abundance and distribution of the Critically Endangered Hirola Antelope (Beatragus hunteri) in Arawale National Reserve, Northeastern, Kenya. Francis Kamau Muthoni Terra Nuova, Transboundary Environmental Project, P.O. Box 74916, Nairobi, Kenya Email: [email protected] 1.0. Abstract. This paper outlines the spatial distribution, population size, habitat preferences and factors causing the decline of Hirola antelope in Arawale National Reserve (ANR) in Garissa and Ijara districts, north eastern Kenya. The reserve covers an area of 540Km2. The objectives of the study were to gather baseline information on hirola distribution, population size habitat preferences and human activities impacting on its existence. A sampling method using line transect count was used to collect data used to estimate the distribution of biological populations (Norton-Griffiths, 1978). Community scouts collected data using Global Positioning Systems (GPS) and recorded on standard datasheets for 12 months. Transect walks were done from 6.00Am to 10.00Am every 5th day of the month. The data was entered into a geo-database and analysed using Arcmap, Ms Excel and Access. The results indicate that the population of hirola in Arawale National Reserve were 69 individuals comprising only 6% of the total population in the natural geographic range of hirola estimated to be 1,167 individuals. It also revealed that hirola prefer open bushes and grasslands. The decline of the Hirola on its natural range is due to a combination of factors, including, habitat loss and degradation, competition with livestock, poaching and drought. Key words: Hirola Antelope Beatragus hunteri, GIS, Endangered Species 2.0. Introduction. The Hirola antelope (Beatragus hunteri) is a “Critically Endangered” species endemic to a small area in Southeast Kenya and Southwest Somalia. -

Camel Prion Disease: a Possible Emerging Disease in Dromedary Camel Populations?
Camel prion disease: a possible emerging disease in dromedary camel populations? ©B. Babelhadj/University Kasdi Merbah, Algeria The identification of a new prion disease in dromedary camels in Algeria and Tunisia, called camel prion disease (CPD), extends the spectrum of animal species naturally susceptible to prion diseases and opens up new research areas for investigation. Camel prion disease was identified in 2018 in adult camels showing clinical signs at the ante mortem inspection at slaughterhouses in the region of Ouargla (Algeria), and in 2019 in the region of Tataouine (Tunisia). It adds to the group of existing animal prion diseases, including scrapie in sheep and goats, chronic wasting disease (CWD) in cervids and BSE (mainly in bovines). The detection of a new prion disease in the dromedary population requires attention and investigation needs to be carried out to assess the risks of this disease to animal and public health. As of today, very limited epidemiological information is available to assess the prevalence, geographical distribution and dynamic of the transmission of the disease. Based on the clinical signs suggesting prion disease, CPD seems to have occurred in 3.1% of the dromedaries brought to the abattoir in Ouargla. Pathognomonic neurodegeneration and disease- specific prion protein (PrPSc) were detected in brain tissue from three symptomatic animals (source: CDC article wwwnc.cdc.gov/eid/article/24/6/17-2007_article). In May 2019, the OIE received a report from Tunisia on a single case of a 12-year-old slaughtered dromedary camel showing neurological signs confirmed as CPD by the Istituto Superiore di Sanità (ISS) based in Italy. -

Camelus Dromedarius) Need Shaded Areas? a Case Study of the Camel Market in Doha
animals Article Do Camels (Camelus dromedarius) Need Shaded Areas? A Case Study of the Camel Market in Doha Martina Zappaterra, Laura Menchetti , Leonardo Nanni Costa and Barbara Padalino * Department of Agricultural and Food Sciences, University of Bologna, Viale Fanin 46, I-40127 Bologna, Italy; [email protected] (M.Z.); [email protected] (L.M.); [email protected] (L.N.C.) * Correspondence: [email protected] Simple Summary: Scientific knowledge concerning dromedary camel behavior and welfare is still limited. To date, providing pens with adequate shaded areas is not regulated in camel husbandry. The objectives of this study were to document whether dromedary camels have a preference for shade and describe how their behavior would change depending on the presence of shade in pens with different animal densities. Analyzing the behavior of camels kept at a permanent market in Doha, we found they had a preference for shade, and adequate shaded areas seemed to exert a positive effect on their behavioral repertoire. Camels in shade expressed more natural behaviors such as lying in sternal recumbency and ruminating, while those in the sun showed more walking and standing. Limited space allowance, instead, seemed to affect camel welfare, increasing the expression of stereotypic behavior (i.e., pacing). Overall, the results of this pilot study suggest that provision of adequate shaded areas could safeguard camel wellbeing under extremely hot conditions.

Amplification of Potential Thermogenetic Mechanisms In
www.nature.com/scientificreports OPEN Amplifcation of potential thermogenetic mechanisms in cetacean brains compared to artiodactyl brains Paul R. Manger1*, Nina Patzke1,10, Muhammad A. Spocter1,2, Adhil Bhagwandin1,11, Karl Æ. Karlsson3, Mads F. Bertelsen4, Abdulaziz N. Alagaili5, Nigel C. Bennett5,6, Osama B. Mohammed5, Suzana Herculano‑Houzel7, Patrick R. Hof8 & Kjell Fuxe9 To elucidate factors underlying the evolution of large brains in cetaceans, we examined 16 brains from 14 cetartiodactyl species, with immunohistochemical techniques, for evidence of non‑shivering thermogenesis. We show that, in comparison to the 11 artiodactyl brains studied (from 11 species), the 5 cetacean brains (from 3 species), exhibit an expanded expression of uncoupling protein 1 (UCP1, UCPs being mitochondrial inner membrane proteins that dissipate the proton gradient to generate heat) in cortical neurons, immunolocalization of UCP4 within a substantial proportion of glia throughout the brain, and an increased density of noradrenergic axonal boutons (noradrenaline functioning to control concentrations of and activate UCPs). Thus, cetacean brains studied possess multiple characteristics indicative of intensifed thermogenetic functionality that can be related to their current and historical obligatory aquatic niche. These fndings necessitate reassessment of our concepts regarding the reasons for large brain evolution and associated functional capacities in cetaceans. Cetaceans (whales, dolphins and porpoises) in general have large relative and absolute brain
