The Okavango Delta: Fisheries in a fluctuating floodplain system
(Frontiers Media [Commercial Publisher], 2022-09-07)Wetlands are among the most productive ecosystems globally characterized by dynamic interactions between terrestrial and aquatic habitats at different scales. These systems support valuable floodplain fisheries that are a ... -
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 ... -
Pastoralists’ perception and ecological knowledge on savanna ecosystem dynamics in semi-arid Botswana
(Resilience Alliance, 2012)We investigated vegetation dynamics in relation to livestock grazing as perceived by pastoral farmers in different regions of Botswana. A structured questionnaire was used to collect farmers’ understanding of vegetation ... -
POISONOUS PLANTS IN GARDENS AND GRAZING LANDS.
(Science-line Publishers, 2011)This paper is a review of poisonous plants, their toxic agents and the symptoms of poisoning. Poisonous plants are plants, which as a whole or part thereof under all or certain conditions and in amount likely to be taken ... -
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 ... -
Pre-sowing treatments for enhancing germination of Guibortia coleosperma and Amblygonocarpus andongensis seeds from Kazuma Forest Reserve, Botswana
(Academic Journal, 2021-09-30)The effect of seed presowing treatment on Guibortia coleosperma and Amblygonocarpus andongensis was investigated. Seeds of both species were subjected to four experiments, containing 10 levels of presowing treatments: ... -
Promoting Bamboo-Based Agroforestry for Enhancing Ecosystem Services from Degraded Lands.
(Springer Singapore, 2021-01-01)Agroforestry innovations on degraded lands have been prioritized for promoting environmental sustainability, advancing food and fodder security, and achieving United Nations Sustainable Development Goals. Although neglected ... -
Rebrowsing by elephants three years after simulated browsing on five woody plant species in northern Botswana
(Southern African Wildlife Management Association (SAWMA), 2005-11-10)Utilization by the African elephant (Loxodonta africana) of five tree species of different acceptability was assessed on trees used three years earlier in a simulated browsing experiment. The experiment included two levels ... -
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 Review of Habitat and Distribution of Common Stingless Bees and Honeybees Species in African Savanna Ecosystems.
(Sage Journals, 2022-05-03)Background and Research Aims: Globally, concerns over a decline in insect pollinator abundance have been raised. Although bees were noted to be key pollinating agents for approximately 52 of the leading 115 global food ... -
Socio-economic factors influencing household forest dependency in Chobe enclave, Botswana.
(Springer Open, 2017)Introduction: Human dependence on forests is a multifaceted phenomenon. The degree of reliance on forests varies geographically, overtime and across communities. These dynamics underpin the importance of understanding the ... -
Spatial and temporal variations of microinvertebrates across temporary floodplains of the lower Okavango Delta, Botswana
(Elservier, 2011-08-06)The connectivity of the Okavango Delta to its temporary floodplains may reduce due to threats of increasing human water demands and climate change. Microinvertebrates in aquatic systems have a regulatory effect on juvenile ... -
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 ... -
Spatial variability of aquatic macroinvertebrate assemblages in the Okavango Delta, Botswana: considerations for developing a rapid bioassessment tool
(Taylor & Francis, 2020-07-02)Spatial variability in macroinvertebrate assemblages of the Okavango Delta, Botswana, was examined to evaluate differences in assemblages at a regional and habitat scale. Sampling was undertaken six times during a one-year ... -
Spatial variability of measured soil properties across site‐specific management zones
(Soil Science Society of America Journal, 2005-09)The spatial variation of productivity across farm fields can be classified by delineating site‐specific management zones. Since productivity is influenced by soil characteristics, the spatial pattern of productivity could ... -
