(Blackwell Publishing Ltd, 2001-09)
Sustainable resource management requires understanding the factors that increase or decrease species richness. Regional species richness patterns may be predicted by analysing patterns of variation in the environment. A ...
Mapping habitat and biological diversity in the Maasai Mara ecosystem
(Taylor & Francis Group, 2003-01-01)
There is need to identify ecosystems that support richer assemblages of biological species in order to preserve habitats and protect the greatest number of species. Remotely sensed data hold tremendous potential for mapping ...
Biodiversity assessment by remote sensing
(2003-11-10)
Measuring the complexity of species in (semi)
natural environments is time consuming and expensive. In
this paper we summarise remote sensing techniques developed
for mapping and monitoring biodiversity of herbivores ...

Sodium X-type faujasite zeolite decomposition of dimethyl methylphosphonate (DMMP) to methylphosphonate: Nucleophilic zeolite reactions I
(Elsevier, 2006-06-20)
Dimethyl methylphosphonate (DMMP), used extensively as a nerve agent simulant, strongly adsorbs in X-type faujasite zeolite and undergoes nucleophilic substitution by the supercage oxygens. Solid state magic angle spinning ...
Reactions of Methyl Iodide and Halopropanes with Na0 Treated and Untreated NaX and NaY Zeolites
(Cambridge University Press, 2005)
Products formed from reactions of methyl iodide, 1-chloropropane, 1-iodopropane and 1-bromopropane with Na0 treated and untreated NaX and NaY zeolites were studied using solid state 13C NMR and IR spectroscopy. At room ...
Effects of Possible Spin-Spin Interactions on EPR spectra of Cu2+ exchanged Faujasite–X (I)
(Cambridge University Press, 2005)
The interpretation of the continuous wave electron paramagnetic resonance (CW-EPR) spectra of Cu2+ exchanged in Faujasite zeolite is not straightforward. Recent literature points to the role of both Cu2+ zeolite sites and ...
