Environmental constraints on the foraging behaviour, spatial usage and population sizes of albatrosses
(University of St Andrews, 2009) - Thesis,
Satellite-tracking of wide-ranging, apex marine predators, combined with remote-sensing, can be used to test ecological hypotheses and to estimate spatial abundance. I
used this approach to quantify the habitat usage of ...
Measuring and understanding biogenic influences upon cohesive sediment stability in intertidal systems
(University of St Andrews, 2008-11) - Thesis,
Intertidal cohesive sediment systems are found throughout the world in areas of low
hydrodynamic energy. These systems are ecologically and economically important
but are under pressure from global warming, sea level ...
Structural biology of Vibrio cholerae pathogenicity factors
(University of St Andrews, 2009-06-26) - Thesis,
The World Health Organization (WHO) states that 30,000 children under the age of five die each day worldwide. Around a quarter of these die from diarrheal disease caused by microbial infection. In addition to this high ...
Structure and function of nitrate and nitrite transporters, NrtA and NitA, from Aspergillus nidulans
(University of St Andrews, 2009-06-26) - Thesis,
Membrane proteins play an integral role in the control of ion transport across the cell membrane in biological systems. However, due to experimental constraints, structural and functional data available for these proteins ...
The control of mitochondrial morphology and dynamics in Arabidopis thaliana
(University of St Andrews, 2006) - Thesis,
Mitochondria are ubiquitous eukaryotic organelles which carry out a range of
essential functions, most notably the production of ATP through the process
of oxidative phosphorylation. While the main biochemical function ...
Variation in sperm whale (Physeter macrocephalus) coda vocalizations and social structure in the North Atlantic Ocean
(University of St Andrews, 2009-11-30) - Thesis,
This study aimed at complementing studies of sperm whale social and vocal behaviour that
were restricted to the Pacific Ocean.
The characteristic multi-pulsed structure of sperm whale clicks allows for estimation of
whales' ...
Female mating decisions in the Trinidadian guppy, Poecilia reticulata
(University of St Andrews, 2009) - Thesis,
Contrary to traditional belief, the decisions that females make before, during and after mating shape its outcome and ultimately fitness. The aim of this thesis was to examine how females modify and adjust their mating ...
Ecological and acoustic investigations of jellyfish (Scyphozoa and Hydrozoa)
(University of St Andrews, 2006-04) - Thesis,
As the biomass of jellyfish (medusae of the Scyphozoa and Hydrozoa) has risen in numerous locations worldwide, awareness of their potential to exert a controlling influence on marine ecosystems and hinder the recruitment ...
Population biology of bottlenose dolphins in the Azores archipelago
(University of St Andrews, 2007-06) - Thesis,
The ranging behaviour, habitat preferences, genetic structure, and demographic parameters of bottlenose dolphins living in the Azores were studied using data collected from 1999 to 2004. Only 44 dolphins out of 966 identified ...
A comparative investigation of nuclear DNA content and its phenotypic impacts in Silene marizii and S. latifolia
(University of St Andrews, 2008) - Thesis,
Considerable variation exists both within and between species in nuclear DNA content. Despite there being no obvious functional role for much of this DNA, many studies have reported phenotypic correlations with genome ...
