During the year 1928 the writer was engaged in a study of the bionomics of the oyster drills on the oyster beds in the region of the River Blackwater, Essex. At this time the presence of a foreign species was detected (1) and definite records were made of the relative abundance of the three following drills or tingles:— Murex erinaceus (=Ocinebra), Purpura lapillus (=Nucella), and Urosalpinx cinerea . It so happened that the winter of 1928–29 was unusually cold; the temperature of the water… Expand

Note on the Temperature Tolerances of some Intertidal animals in Relation to Environmental Temperatures and Geographical Distribution
TLDR
It is clear that the temperatures experienced on the shore are well within the tolerance limits of most of the animals, and even exceptional extremes of temperature may have little direct influence on the distribution of adult intertidal animals. Expand
Aspects of the ecology of an exposed shore population of dogwhelks Nucella lapillus (L.)
TLDR
Up to the third year of life Nucella lapillus (L.) could be aged in the laboratory and in the field using shell characters, and it was suggested that mortality rate decreased with age, and this was confirmed by calculating annual mortality rates. Expand
The Japanese oyster drill Ocinebrellus inornatus (Récluz, 1851) (Mollusca, Gastropoda, Muricidae), introduced to the Limfjord, Denmark
TLDR
The predatory neogastropod Ocinebrellus inornatus is reported on the occurrence of the species in beds of European oysters in the Limfjord, NW Jutland, Denmark and its morphology-based identification has been confirmed by genetic analysis. Expand
The relationship between the lethal freezing temperatures and the amounts of ice formed in the foot muscle of marine snails (Mollusca: Gastropoda).
TLDR
The physiological mechanism responsible for the differences in the lethal freezing temperatures of the muscles of the intertidal snails is associated with an increased tolerance to a factor other than the amounts of tissue ice formed. Expand
The biology of Purpura lapillus. Part III. Life history and relation to environmental factors
TLDR
The eggs of Purpura are laid in vase-shaped capsules, attached in clusters to the rocks, and most of these ova are unfertilized and serve as food for the few embryos which develop. Expand
The effect of an invasive species on predation rates upon intertidal barnacles
TLDR
Warming air and oceanic temperature trends are expected to alter the distribution and abundance of both native and invasive species, and the effects of which are effectively predicted using this study. Expand
The effect of an invasive species on predation rates upon intertidal barnacles
TLDR
Warming air and oceanic temperature trends are expected to alter the distribution and abundance of both native and invasive species, and the effects of which are effectively predicted using this study. Expand
Recovery, statistical validation and analysis of a historical meteorological dataset collected at the Hanbury Botanical Gardens (Liguria, northwestern Italy) from 1900 to 1940
A historical set of daily meteorological data collected at the Hanbury Botanical Gardens (Liguria, northwestern Italy) from 1900 to 1940 was recovered from five manually entered registers. They wereExpand
BIOLOGICAL AND HYDROGRAPHIC CHANGES IN BRITISH SEAS DURING THE LAST THIRTY YEARS
TLDR
The physical environment of the English Channel during the 'twenties and 'thirties' and the long-term changes in Sea herring populations in the North Atlantic are described. Expand
The American whelk tingle, Urosalpinx cinerea (Say), on British oyster beds
The American whelk tingle, Urosalpinx cinerea (Say), a gastropod enemy of oysters, has been introduced to Britain with American oysters and is now established in the rivers Blackwater, Colne, CrouchExpand
