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 ...
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 ...
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. ...
The effect of purified condensed tannins of forage plants from Botswana on the free-living stages of gastrointestinal nematode parasites of livestock.
(Elsevier, 2013-10-18)
The effect of condensed tannins (CT) extracted from forage plants from Botswana on the free-living stages of a number of species of gastrointestinal nematode parasites derived from infected sheep were investigated using ...
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 ...
The impact of stable flies (stomoxys calcitrans l.) on small stock production in Bodibeng, Bothatogo and Sehithwa in the north west district, Botswana; a survey study.
(Scienceline Publishers, 2022-03-25)
Stable fly, Stomoxys calcitrans L. (Diptera: Muscidae) is a globally recognized livestock pest of economic importance, which also attacks wild animals, pets and humans. These flies frequently feed on the forelegs of animals ...
Dynamics for a non-autonomous fall armyworm-maize interaction model with a saturation functional response
(AIMS Press, 2021-11-09)
In this study, we present a non-autonomous model with a Holling type II functional response, to study the complex dynamics for fall armyworm-maize biomass interacting in a periodic environment. Understanding how seasonal ...
A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters.
(Springer Open, 2020-06-11)
Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ...
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 ...
Changes in Health-related Parameters Associated with Sports Performance Enhancement Drugs.
(Thieme Gruppe, 2022-12-02)
The purpose of this study was to evaluate changes in health-related parameters caused by the administration of anabolic-androgenic steroids and fat-burning drugs during a 6-month competition preparation period. The ...
