First Observations of Nectar-Drinking Lizards on the African Mainland
Plant Ecology and Evolution 152 (1): 78–83, 2019 https://doi.org/10.5091/plecevo.2019.1513 SHORT COMMUNICATION First observations of nectar-drinking lizards on the African mainland Petra Wester1,2 1Institute of Sensory Ecology, Heinrich-Heine-University, Universitätsstr. 1, D-40225 Düsseldorf, Germany 2School of Life Sciences, University of KwaZulu-Natal, Private Bag X01, Pietermaritzburg 3209, South Africa Email: [email protected] Background and aims – Pollination of flowers is performed mainly by insects, but also by vertebrates. In South Africa, beside birds, non-flying mammals contribute to pollination. During video surveillance of plants adapted to non-flying mammal pollination, surprisingly, lizards were observed at the flowers. The question was addressed whether the lizards consume nectar and whether they could be potential pollinators of these plants. Methods – Flowering Massonia grandiflora in the Cederberg and Eucomis regia (both Asparagaceae) in Namaqualand of South Africa were monitored with camcorders and camera traps for potential flower visitors. The footage was analysed for the type of floral visitor, foraging behaviour, contact areas of the plants’ reproductive organs on the animals as well as potential pollen transfer between animals and flowers. Key results – The Cape cliff lizard Hemicordylus capensis (Cordylidae) visited the flowers of M. grandiflora and the Namaqua day gecko Rhoptropella ocellata (Gekkonidae) visited E. regia flowers, both licking nectar. Thereby, the lizards touched the reproductive organs of the flowers and got dusted with pollen (at least H. capensis) on the same area of their head. Conclusions – Visitation and pollination of flowers by lizards is a rarely observed phenomenon, especially in continental ecosystems. -

Traditional Use and Management of Ntfps in Kangchenjunga Landscape: Implications for Conservation and Livelihoods Yadav Uprety1*, Ram C
Uprety et al. Journal of Ethnobiology and Ethnomedicine (2016) 12:19 DOI 10.1186/s13002-016-0089-8 REVIEW Open Access Traditional use and management of NTFPs in Kangchenjunga Landscape: implications for conservation and livelihoods Yadav Uprety1*, Ram C. Poudel2, Janita Gurung3, Nakul Chettri3 and Ram P. Chaudhary1,4 Abstract Non-timber Forest Products (NTFPs), an important provisioning ecosystem services, are recognized for their contribution in rural livelihoods and forest conservation. Effective management through sustainable harvesting and market driven commercialization are two contrasting aspects that are bringing challenges in development of NTFPs sector. Identifying potential species having market value, conducting value chain analyses, and sustainable management of NTFPs need analysis of their use patterns by communities and trends at a regional scale. We analyzed use patterns, trends, and challenges in traditional use and management of NTFPs in the southern slope of Kangchenjunga Landscape, Eastern Himalaya and discussed potential implications for conservation and livelihoods. A total of 739 species of NTFPs used by the local people of Kangchenjunga Landscape were reported in the reviewed literature. Of these, the highest number of NTFPs was documented from India (377 species), followed by Nepal (363) and Bhutan (245). Though the reported species were used for 24 different purposes, medicinal and edible plants were the most frequently used NTFP categories in the landscape. Medicinal plants were used in 27 major ailment categories, with the highest number of species being used for gastro-intestinal disorders. Though the Kangchenjunga Landscape harbors many potential NTFPs, trade of NTFPs was found to be nominal indicating lack of commercialization due to limited market information. -

Building Guidelines Apply to Landscaping Contractors As Well
LANDSCAPING GUIDELINES Revised 23 February 2017 Version 5 THE PURPOSE OF THE LANDSCAPING GUIDELINES INTRODUCTION Arabella Country Estate is situated within the Kogelberg Biosphere Reserve within the Cape Fynbos Region. This is one of the richest plant kingdoms in the world with an incredible variety of flowers and shrubs. It is an area that is also prone to long dry periods with variable or no rainfall. As a part of the Biosphere Arabella is committed to protecting the biodiversity of plants and animals within the reserve and to co-operating in avoiding the introduction of plants or animals which may pose a threat to this diversity. The Estate is also committed to the conservation and wise use of water resources. Additionally, South Africa has promulgated Regulations in terms of the Conservation of Agricultural Resources Act (CARA). The Schedules to this Act set out plants, not allowed on private land. Failure to remove such plants is an offence and landowners are liable to prosecution. It is in our interest to comply with these regulations. The Landscaping Guidelines are intended to help private homeowners: Help the Estate contribute to the goals of the Biosphere Reserve Avoid breaching the CARA Regulations, and Have a water wise garden that will save water and thus save money. WHEN STARTING A GARDEN IT IS STRONGLY RECOMMENDED THAT a qualified landscaping consultant is employed to guide you in your choices. Many of the surrounding nurseries or landscaping contractors have the knowledge to advise you in your planting. Revised 23 February 2017 Version 5 1. PRIVATE HOME GARDENS 1.1 Plant Material 1.1.1 Only South African indigenous plants may be used, preferably those, which are endemic (Cape Flora). -

Mice Pollinate the Pagoda Lily, Whiteheadia Bifolia
Available online at www.sciencedirect.com South African Journal of Botany 75 (2009) 713–719 www.elsevier.com/locate/sajb Mice pollinate the Pagoda Lily, Whiteheadia bifolia (Hyacinthaceae) — First field observations with photographic documentation of rodent pollination in South Africa ⁎ P. Wester , R. Stanway, A. Pauw Department of Botany and Zoology, University of Stellenbosch, Private Bag X1, Stellenbosch 7602, South Africa Received 31 March 2009; received in revised form 3 July 2009; accepted 7 July 2009 Abstract For the first time in South Africa nocturnal rodent pollination was observed and photographed under natural conditions. In the Northern Cederberg area of the Western Cape field studies and experiments showed that flowers of Whiteheadia bifolia (Hyacinthaceae) are visited at night by rodents, mainly the Namaqua Rock Mouse Aethomys namaquensis. The mice were observed licking nectar while being dusted with pollen and touching the stigmas. No other visitors were observed during the day or night. W. bifolia pollen was found around the snouts and in the faeces of live-trapped mice, the latter likely as a result of grooming their fur, since they visited the flowers without eating or destroying them. W. bifolia has characters of the rodent pollination floral syndrome such as visually inconspicuous, bowl-shaped flowers close to the ground, with stiff stamens as well as easily accessible, very viscous nectar and a weak, slightly sourish-nutty scent. Furthermore, these findings support the hypothesis that pollination syndromes can be used to make testable predictions about floral trait evolution due to pollinator selection. © 2009 SAAB.
