Grey seal maternal attendance patterns are affected by water availability on North Rona, Scotland
(2001-06) - Journal article,
Previous studies on grey seals (Halichoerus grypus) have shown that pools of water influence female distribution within inland breeding colonies. This study reveals that the availability of pools also affects maternal ...
Grey seal (Halichoerus grypus) pup mortality is not explained by local breeding density on the Island of North Rona, Scotland
(2003-01) - Journal article,
Pre-weaning pup mortality of grey seals Halichoerus grypus in a breeding colony (North Rona, Scotland, U.K.) was examined in relation to the density of local adult females over two breeding seasons. Accurate, fine-scale ...
Influence of the physical environment and conspecific aggression on the spatial arrangement of breeding grey seals
(2007-12) - Journal article,
Understanding the habitat requirements of a species for breeding is essential for its conservation, particularly if the availability of suitable habitat is a limiting factor for population growth. This is postulated to be ...
A fine scale study finds limited evidence of kin clustering in a grey seal colony
(2008-04) - Journal article,
Microsatellites were used to investigate fine-scale spatial and temporal genetic structure of a gray seal breeding colony, using samples collected throughout the colony (1997) and more extensive local sampling (2000-2002). ...
The scaling of diving time budgets : insights from an optimality approach
(2008-03) - Journal article,
Simple scaling arguments suggest that, among air-breathing divers, dive duration should scale approximately with mass to the one-third power. Recent phylogenetic analyses appear to confirm this. The same analyses showed ...
Rapid regulation of protein activity in fission yeast
(2008-05-05) - Journal article,
Background: The fission yeast Schizosaccharomyces pombe is widely-used as a model organism for the study of a broad range of eukaryotic cellular processes such as cell cycle, genome stability and cell morphology. Despite ...
MCM-GINS and MCM-MCM interactions in vivo visualised by bimolecular fluorescence complementation in fission yeast
(2009-02-19) - Journal article,
Background: Each of the three individual components of the CMG complex (Cdc45, MCM and GINS) is essential for chromosomal DNA replication in eukaryotic cells, both for the initiation of replication at origins and also for ...
Behavioral evidence of thermal stress from overheating in UK breeding gray seals
(2002-04) - Journal article,
Gray seals (Halichoerus grypus) in the UK exhibit clear preferences for pupping close to pools of water on inland breeding sites. The reasons for this are unclear as seals are thought to derive all their water requirements ...
The evolution of hermaphroditism by an infectious male-derived cell lineage : an inclusive-fitness analysis
(2011-08) - Journal article,
There has been much recent interest in the role for genetic conflicts to drive the evolution of genetic systems. Here we consider the evolution of hermaphroditism in the scale insect tribe Iceryini and the suggestion that ...
Haplodiploidy and the evolution of eusociality : split sex ratios (vol 179, pg 240, 2012)
(2012-04) - Journal article,
