Molecular genetics of 2, 4-dichlorophenoxyacetate (2, 4-D) degradation in pseudomonas cepacia strain 2a
Pseudomonas cepacia strain 2a, which utilises2,4-dichlorophenoxyacetate (2,4-D) as a sole source of carbon and energy, has been shown to contain an 17kbp plasmid, p2,4-D, which has been mapped using BamHI and Asp718. Several mutants of strain 2a unable to grow on 2,4-D were generated by temperature …

Developing conservation governance strategies: holistic management of protected areas in Nepal
The Buffer Zone (BZ) concept has been introduced in Nepal as a key component of the national biodiversity conservation strategy to mitigate the impacts of protected areas on local communities, and thereby reduce adverse impacts of local people on protected areas. Unlike traditional Buffer Zone …

Seed dispersal effectiveness of samango monkey (Cercopithecus albogularis schwarzi)
The effectiveness of a seed disperser is dependent on the impact it has on plant fitness. For fruiting species, plant fitness is dependent on the behaviour of its mutualists in (a) reducing seed mortality and (b) increasing the likelihood of future reproduction. The main aim of this thesis was to …

Cranial remains from the graveyard to the laboratory: restoration, conservation and craniometric analysis of medieval British skeletal samples
The present thesis proposes a comparison of 16 British medieval samples by means of craniometric analysis. The purpose of this study is to determine whether craniometric variation among British medieval groups exists and what are the causes of these differences. Following the reconstruction of 267 …

Vanadium uptake and transport in higher plants
The uptake and transport of vanadium in several higher plant species has been examined. Studies utilizing excised Hordeum roots have revealed the uptake patterns of two different ionic species of vanadium (V02+ and V03) to be similar. Both ionic forms exhibited a large extracellular component in …
