In a recent work, Wang et al (2004) demonstrated differential regulation of lymphoma xenografts utilising species-specific receptor antibodies to VEGFR-1 and VEGFR-2.
Vegetation types provide information on habitats that are utilised by species other than plants, are often linked to specific characteristics of the physical environment and depict more ecological complexity than individual taxa (Scott et al. 1993; Margules et al. 2002).
Despite sharing the landscape with domestic cattle and introduced game, leopards in the Soutpansberg do not frequently utilise these species as prey and instead focus their diets on wild species.
This, however, does not mean that they would utilise plant species within these habitats in proportion to availability, but rather would show a stronger selection for habitats compared to plants.
This greatly enhances our ability to utilise this species as an experimental model in neuroscience and metabolism, with the potential to enable development of molecular tools that could manipulate the physiology and behaviour of this agricultural and horticultural pest species.
Grazers and browsers utilise species-specific depth ranges, and species in the same depth range choose the substratum types on which they feed [ 10, 23, 30].
This allowed us to gather information on the products and species utilised, amounts used, and local prices which allowed for the calculation of direct use values.
Moreover, facilitative interactions due to, for example, cross-feeding, might have been of minor importance due to the nature of the supplied substrates, which were probably completely degraded and therefore unlikely to have produced metabolic by-products that could be utilised by other species.
The genomic specification of Syt1 expression patterns, has been investigated and utilised in ascidian species [ 99- 102].
The genetic toolkit utilised by a species is represented in its genome, and direct assessment of the genetic capabilities of an organism can thus be assessed through analysis of genome data.
