Volume–biomass functions reveal the effect of browsing on three Moroccan dwarf shrubs
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Z Akasbi --- Biodiversity, Evolution and Ecology of Plants, Germany J Oldeland --- Biodiversity, Evolution and Ecology of Plants, Germany J Dengler --- Biodiversity, Evolution and Ecology of Plants, Germany M Finckh --- Biodiversity, Evolution and Ecology of Plants, GermanyWe studied the effects of browsing on the plant architecture and volume-biomass relationships of three dominant dwarf shrubs – Artemisia herba-alba, A. mesatlantica and Teucrium mideltense – in a sagebrush steppe in the Central High Atlas Mountains, southern Morocco. For... -
Solving the challenges of monitoring mobile populations: insights from studies of waterbirds in southern Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Hannah L Thomas --- Percy FitzPatrick Institute, DST–NRF Centre of Excellence, South Africa Philip AR Hockey --- Percy FitzPatrick Institute, DST–NRF Centre of Excellence, South Africa Graeme S Cumming --- Percy FitzPatrick Institute, DST–NRF Centre of Excellence, South AfricaHighly mobile species are difficult to monitor. It is often unclear from abundance estimates whether a population is genuinely declining or simply elsewhere. If the spatial and temporal scales of monitoring are inadequate, the data will only be useful if... -
Using independent nest survey data to validate changes in reporting rates of Martial Eagles between the Southern African Bird Atlas Project 1 and 2
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Arjun Amar --- DST–NRF Centre of Excellence at the Percy FitzPatrick Institute of African Ornithology, South Africa Daniël Cloete --- DST–NRF Centre of Excellence at the Percy FitzPatrick Institute of African Ornithology, South Africa Madel Whittington --- Birds of Prey Programme, Endangered Wildlife Trust, Nossob camp, South AfricaRepeat monitoring is vital to measure biodiversity change. However, monitoring protocols may change, as survey techniques improve or different questions are asked. Such modifications may cause difficulties when examining changes in wildlife populations. The Southern African Bird Atlas Project (SABAP)... -
Spatial distribution and breeding territories of Bonelli’s Eagle Aquila fasciata in the western Anti-Atlas Mountains, Morocco
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Ali Irizi --- Département de Zoologie et Ecologie Animale, Institut Scientifique, Morocco Mohamed Aourir --- Laboratory « Biodiversité et fonctionnement des écosystèmes », Department of Biology, Faculty of Sciences, Morocco Mohammed Znari --- Laboratoire « Biodiversité et Dynamique des Ecosystèmes», Faculté des Sciences – Semlalia, Morocco Mohamed Aziz El Agbani --- Département de Zoologie et Ecologie Animale, Institut Scientifique, Morocco Abdeljebbar Qninba --- Département de Zoologie et Ecologie Animale, Institut Scientifique, MoroccoThe North African population of Bonelli’s Eagle Aquila fasciata (Vieillot, 1822) is limited to the south by the northern fringe of the Sahara Desert. This study provides the first data on the spatial distribution and density of breeding Bonelli’s Eagles... -
Point counts outperform line transects when sampling birds along routes in South African protected areas
Item type: Journal Article • Journal: African Zoology • Authors: Graeme S Cumming --- ARC Centre of Excellence for Coral Reef Studies, Australia Dominic AW Henry --- FitzPatrick Institute, South AfricaBird atlases have become an important source of distribution data for broad-scale analyses in ecology, biogeography and conservation. However, national bird atlases are undertaken in different ways in different countries, usually with little formal assessment of alternatives. Existing research suggests... -
Bucking the trend: the African Black Oystercatcher as a recent conservation success story
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Mark Brown --- School of Life Sciences, South Africa Brittany Arendse --- Nature’s Valley Trust, Nature’s Valley, South Africa Bruno Mels --- Nature’s Valley Trust, Nature’s Valley, South Africa Alan TK Lee --- School of Life Sciences, South AfricaThe African Black Oystercatcher Haematopus moquini is a charismatic, southern African near-endemic, wader species, that is often seen as a flagship species for coastal bird conservation, as it was recently down-listed regionally to Least Concern on the IUCN Red List... -
BirdLasser: The influence of a mobile app on a citizen science project
Item type: Journal Article • Journal: African Zoology • Authors: Alan Tristram Kenneth Lee --- , South Africa Henk Nel --- , South AfricaIn recent decades, people across the world have adopted ‘smart-phones’ and their technology. Software applications on these devices have become diverse in their functionality and easy to use. Citizen science projects that try to mobilise data collection from people from... -
South African raptors in urban landscapes: a review
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Shane C McPherson --- , South Africa Petra Sumasgutner --- , Austria Colleen T Downs --- , South AfricaGlobally, but especially in Africa, increasing human populations and anthropogenic land-use change are generally affecting diversity negatively. Urban environments in southern Africa typically comprise a mosaic landscape of anthropogenic infrastructure with some green spaces. These urban cities have a range... -
