The effect of temperature during cone and seed development on primary dormancy of Scots pine (Pinus sylvestris L.) seeds
(Springer, 2021)Scots pine (Pinus sylvestris L.) seeds have variable levels of primary dormancy which reflect within-species adaptation to local environments. The objective of this study was to use a thermal time approach to determine ... -
Response of Aspen Suckers to Simulated Browsing.
(Oxford Academic, 2014-04-02)Heavy and repeated ungulate browsing on reproductive suckers has limited quaking aspen (Populus tremuloides Michx.) regeneration on many Western landscapes. However, little is known about the specific effects of season and ... -
A flood pulse driven fish population model for the Okavango Delta, Botswana.
(Elsevier, 2012-03-10)The Okavango Delta is a large, remote, and ecologically significant wetland located in Botswana that receives a strong annual flood pulse. Although the hydrology in flood pulsed systems is often theorized to drive fish ... -
A case for gender equity in governance of the Okavango Deltafisheries in Botswana
(Wiley Online Library, 2012-05-22)Fish is a major source of livelihood for the majority of people living around the Okavango Delta in north western Botswana. Gender dynamics and governance regimes determine differential access to, and control of, resources ... -
The tropical African mercury anomaly: Lower than expected mercury concentrations in fish and human hair.
(Elsevier, 2011-02-20)Mercury is a neurotoxin and global pollutant, and wetlands and newly flooded areas are known to be sites of enhanced production of monomethylmercury, the form of mercury that is readily biomagnified in aquatic food chains ... -
Potential impacts of biofuel development on food security in Botswana: A contribution to energy policy.
(Elsevier, 2012-01-20)Biofuel development continues to be a critical development strategy in Africa because it promises to be an important part of the emerging bio-economy. However, there is a growing concern that the pattern of biofuel development ... -
Fish, Floods, and Ecosystem Engineers: Aquatic Conser- vation in the Okavango Delta, Botswana.
(American Institute of Biological Sciences, 2009-01-01)The Okavango Delta, Botswana, is a major wetland surrounded by the Kalahari Desert. The delta supports a diverse fish fauna that depends on highly seasonal flooding from inflowing rivers, and on the actions of ecosystem ... -
Spatial refuges buffer landscapes against homogenisation and degradation by large herbivore populations and facilitate vegetation heterogeneity.
(Sabinet African Journals, 2017-08-16)Environmental heterogeneity across savanna landscapes, including different seasonal resources at different distances to water, may play a critical role in maintaining the size and diversity of wildlife populations and the ... -
The vegetation and wildlife habitats of the Savuti-Mababe-Linyanti ecosystem, northern Botswana.
(Sabinet African Journals, 2017-05-23)This study classified the vegetation of the Savuti-Mababe-Linyanti ecosystem (SMLE), northern Botswana and developed a detailed map that provides a reliable habitat template of the SMLE for future wildlife habitat use ... -
Land use, rangeland degradation and ecological changes in the southern Kalahari, Botswana
(Wiley Online Library, 2016-02-09)Dual-scale analyses assessing farm-scale patterns of ecological change and landscape-scale patterns of change in vegetation cover and animal distribution are presented from ecological transect studies away from waterpoints, ... -
Overcoming seed dormancy of senegalia galpinii and vachellia robusta through scarification pre-sowing treatments.
(Semantic Scholar, 2020-03-30)The seeds of Senegalia galpinii (Burtt Davy) Seigler and Ebinger and Vachellia robusta (Burch.) Kyalangalilwa and Boatwright have hard coatimposed dormancy that prevents water and air from entering the seeds, which is ... -
Germination studies on seeds of Burkea africana and Erythrophleum africanum from Kazuma Forest Reserve, Northern Botswana
(Academic Journals, 2020-09)Burkea africana and Erythrophleum africanum are characterized by seed coat-imposed dormancy that prevents water entry and gaseous exchange, which are essential for the germination process. The objective of this study was ... -
Dimensional Relations and Physical Properties of Wood of Acacia saligna, an Invasive Tree species growing in Botswana
(International Science Community Association, 2013-07-06)A study was carried out to evaluate wood physical properties of Acacia saligna, an invasive alien species that has naturalized in Botswana. Wood samples were collected from three different trees at three different heights ... -
Community Perspective on State Forest Management Regime and its Implication on Forest Sustainability: A Case Study of Chobe Forest Reserve, Botswana
(Taylor & Francis Online, 2020-01-31)Forest management regimes have evolved worldwide over time in a quest to protect and conserve forests. This paper analysed local communities’ perspectives on the existing management regime for the Chobe Forest Reserve, ... -
The use of analytic hierarchy process (AHP) for stakeholder preference analysis: A case study from Kasane Forest Reserve, Botswana
(Academic Journals, 2012-10-31)Public participation in decision making on management of forest resources is crucial to the planning and sustainable development approach. Rarely, however, are efforts made to measure local stakeholder preferences for ... -
