A novel pentacyclic triterpene glycoside from a resin of Commiphora glandulosa from Botswana
(African Journal of Pharmacy and Pharmacology, 2010)
A novel ursane-type pentacyclic triterpene glycoside, 1β,2β,3β-trihydoxy-urs-12-ene-23-oic-rhamnoside was isolated from the resin of Commiphora glandulosa Schinz by bioassay guided fractionation. Crude aqueous and chloroform ...
Seed dispersal by serrated tortoises (Psammobates Oculiferus) and the effect of their gut passage on seed germination.
(Researchgate, 2014-10-27)
Some tortoises are frugivores and can disperse seeds away from the parent plant to areas favourable for their establishments through gut passage. We investigated the plant species dispersed by the serrated tortoise ...
Effects of chemical preservatives and water quality on postharvest keeping quality of cut Lisianthus (Eustoma grandiflorum L)
(Botswana University of Agriculture and Natural resources, 2013)
This study was carried out to investigate effects of various chemicals added to vase solutions and also effects of water quality on the post-harvest physiology of Lisianthus (Eustoma grandiflorum L.) cut stems. The vase ...
Gross and microanatomical changes at the weight bearing points of ostrich induced by soil or concrete floor and implications for welfare.
(Botswana University of Agriculture and Natural resources, 2013)
This study investigated the gross and microanatomical changes occurring at the weight bearing points on the ostrich body surface induced by rearing on soil floor or on concrete floor and the implications for the welfare ...
The challenges of Ilaje youth in combining education with artisanal fishing in Ondo State, Nigeria.
(Botswana University of Agriculture and Natural resources, 2013)
The study examined how Ilajes in-school youth entrepreneurs combined their education with fishing activities in Ondo State. It examined their personal characteristics, period of involvement and educational activities. ...
Condensed tannins from Botswanan forage plants are effective priming agents of γδ T cells in ruminants.
(Elsevier, 2012-03-05)
The potential impact of extracts from forage plants on y8 T cell activity in ruminants was evaluated using an in vitro immunoassay. This study investigated whether plant extracts could prime y8 T cells via up-regulation ...
Responses of leaf parameters of Arabidopsis thaliana ecotypes to change in CO2 concentrations.
(Botswana University of Agriculture and Natural resources, 2013)
An increase in anthropogenic generation of carbon dioxide (CO2) is one of the characteristic features of global climate change. How plants respond to this change has critical implications for the performance of both natural ...
A mathematical model for fall armyworm management on maize biomass
(SpringerLink, 2012)
Fall armyworm (Spodoptera frugiperda), a highly destructive and fast spreading agricultural pest native to North and South America, poses a real threat to global food security. In this paper, to explore the dynamics and ...
Drought and grazing influence on Northern Chihuahuan desert rangelands, New Mexico.
(Botswana University of Agriculture and Natural resources, 2013)
A short term cattle grazing trial was started in June 1992 in the Chihuahuan Desert in Southern New Mexico to study the influence of drought and grazing on plant responses. Paddocks were grazed in June and September each ...
Deposition rates of atmospheric particulates determined from 210Pb measurements in soils and air
(HARD Publishing, 2010)
Deposition rates of atmospheric particles were determined using previously published
210Pb data in soils and air. The dry deposition velocities for moorland and woodland soils
were 2.2±1.8 and 9±2 mm• s-1, respectively. ...
