Species and size differences in the digestion of otoliths and beaks: Implications for estimates of pinniped diet composition
TLDR
Estimates of prey size and diet composition require otoliths from faeces to be graded and more complex correction factors applied and the application of species, size, and grade-specific correction factors progressively improved reconstructed estimates of prey biomass fed. Expand
Subtle population structuring within a highly vagile marine invertebrate, the veined squid Loligo forbesi, demonstrated with microsatellite DNA markers
TLDR
The demonstration of genetic subdivision in an abundant, highly mobile marine invertebrate has implications for the interpretation of dispersal and population dynamics, and consequent management, of such a commercially exploited species. Expand
Abundance of demersal fish resources in the Persian Gulf and Oman Sea
We report on results of a trawl survey during 2003–2004 to assess the abundance of demersal fish resources in the Persian Gulf and Oman Sea. Samples were taken at a total of 316 trawl stationsExpand
Assessing the importance of cephalopods in the diets of marine mammals and other top predators: problems and solutions
Abstract The methodology typically used in the analysis of predator diets is subject to a range of errors and biases and these are reviewed in relation to estimating the consumption of cephalopods byExpand
Travelling through a warming world: climate change and migratory species.
TLDR
This multi- taxon review shows that the characteristics of species that undertake such movements appear to make them particularly vulnerable to detrimental impacts of climate change, and conservation strategies for migrants will require substantial shifts in site designation policies, flexibility of management strategies and the integration of forward planning.

TAXONOMIC STATUS AND GEOGRAPHICAL CRANIAL VARIATION OF COMMON DOLPHINS (DELPHINUS) IN THE EASTERN NORTH ATLANTIC
TLDR
The common dolphin in the eastern North Atlantic is regarded here as a large form of Delphinus delphis, based on skulls obtained from both stranded and bycaught individuals collected between 1901 and 2005. Expand
Modelling of essential fish habitat based on remote sensing, spatial analysis and GIS
We review the variety of existing modelling approaches applied to species habitat mapping and we discuss issues arising from the availability and nature of sampled biological data and correspondingExpand
Common trends in northeast Atlantic squid time series
Abstract In this paper, dynamic factor analysis is used to estimate common trends in time series of squid catch per unit effort in Scottish (UK) waters. Results indicated that time series of mostExpand
An overview of commercial fishers’ attitudes towards marine protected areas
Marine protected areas (MPAs) are attracting widespread attention worldwide as a tool for fishery management and marine ecosystem conservation. The establishment of MPAs has increased greatly inExpand
