Journal of East African Natural History 2021-04-01T12:57:58+00:00 Benny Bytebier Open Journal Systems <p>The <em>Journal of East African Natural History </em>is published jointly by the East Africa Natural History Society and the National Museums of Kenya. The <em>Journal</em> publishes papers and notes in the field of natural history, broadly defined as the study of organisms in their natural state, relevant to the eastern African region. Of particular interest are contributions that add to our knowledge of the status and conservation of biological diversity in the region. Since the biological landscape is to a large extent shaped by man, papers on ethnobiology will also be considered. Contributions can be substantial articles, short notes and book reviews.</p> <p>More info on the journal can be found <a title="" href="" target="_blank" rel="noopener">here:&nbsp;</a></p> <p>Other websites related to this journal:&nbsp;<a title="" href="" target="_blank" rel="noopener"></a></p> <p>&nbsp;</p> Distance from the tourist trail and daylight condition affect the abundance of Mwanza flatheaded rock agama (<I>Agama mwanzae</I>) in Saanane National Park, Tanzania 2021-04-01T12:38:32+00:00 Daud M. Gunda Ladislaus W. Kahana Obeid Mahenya Teresa J. Sylvina Abraham Eustace <p>For newly established protected areas, it is important to document the abundance, structure and distribution of the species within the landscape. Here we assessed the variation in total abundance as well as female, male and juvenile abundance of Mwanza flat-headed rock agama (Agama mwanzae) in Saanane National Park, Tanzania, in relation to daylight condition (sunny and non-sunny) and proximity to humans. Twenty-three points of 50-meter radius were randomly placed and thoroughly searched for A. mwanzae. Of 364<br>individual Mwanza flat-headed rock agamas recorded, 85% were adults and 15% were juveniles. Among adults, 45% were males and 55% were females. Daylight condition was observed to affect total abundance and the abundance of females, males and juveniles of A.<br>mwanzae, with higher abundance being in sunny periods as compared to non-sunny periods. Distance from the tourist trail was the best predictor for total abundance and the abundance of females and juveniles but not males, with abundance decreasing moving<br>away from the tourist trail. Therefore, we suggest these factors be considered when surveying agamas elsewhere.</p> <p><strong>Keywords:</strong> daylight period; disturbance; human influence; tourist trail; landscape ecology; sunny period </p> 2021-04-01T00:00:00+00:00 Copyright (c) Growth rates in the giant rosette plants <I>Dendrosenecio adnivalis </I>and <I>Lobelia wollastonii</I> on the Ruwenzori Mountains, Uganda 2021-04-01T12:53:46+00:00 Thomas T. Struhsaker <p>Stem lengths of <em>Dendrosenecio adnivalis</em> and <em>Lobelia wollastonii</em> were measured three times over 5.5 years in the Ruwenzori Mountains, Uganda. These are the only growth data for these two species. Both species had highly variable growth rates. Absolute growth rates in <em>D. adnivalis</em> were not related to the number of rosettes, inflorescences or initial height of plants. The <em>D. adnivalis</em> that were shorter at the beginning of the study grew proportionately faster than did taller individuals. Growth rate was positively associated with annual rainfall for <em>D. adnivalis</em> on the Ruwenzori Mountains, <em>D. keniodendron</em> on Mount Kenya, and <em>D. battiscombei</em> on the Aberdare Mountains. <em>Lobelia wollastonii</em> that were taller at the beginning of the study had greater absolute growth rates than did shorter plants. There was no significant relationship between the initial height and proportional increase in height for <em>L. </em><em>wollastonii.</em> Growth rate and height are unreliable indicators of age for both species.</p> <p><strong>Keywords</strong>: Dendrosenecio, Lobelia, growth rates, Ruwenzori Mountains </p> 2021-04-01T00:00:00+00:00 Copyright (c) Ann Birnie: In Memoriam 2021-04-01T12:46:43+00:00 Benny Bytebier <p>No Abstract.</p> 2021-04-01T00:00:00+00:00 Copyright (c)
