Surface catches of diatoms taken in Hudson bay in August and September 1930, revealed well-known species of arctic origin. They were most abundant and in best condition near the mouth of the bay, decreasing rapidly inwards, irrespective of the water temperature or the time of the catch.

Oceanographic Conditions

The waters of Hudson bay differ markedly from the waters of Hudson strait and the waters of the open ocean. Intense stratification in the upper twenty-five metres, decreasing as the waters of the open ocean are approached, gives Hudson bay the character of a large estuary. Below fifty metres the waters are for all purposes dynamically dead, thus resulting in a cold saline body of water which probably undergoes very little change from season to season. The movements of the waters at various levels are dealt with to show that the inflow of waters from Fox channel and the many fresh-water drainage areas control the hydrographic conditions as found. The main water movement is from the James bay area to Hudson strait and thence to the open ocean.

Sixty-eight collections of marine algae made during the summers of 1927 to 1930 inclusive gave only one hundred and seventy one identifications, comprising forty species, none peculiar to this region alone. The distribution and appearance of the plants indicate that the algal association of Hudson bay is estuarial and arctic.

The Hudson bay, a great inland sea situated well to the south of the arctic circle, has its two entrances at the northern extremity, one into the Arctic ocean and the other through Hudson strait into Davis strait. As the whole region lies within the area of the most recent glaciation, its fauna must have been re-established since the recession of the glacier from northern sources. This will probably explain the fact that practically all of the species are those of Greenland and arctic America, which in turn are chiefly circumpolar in distribution.Collections made in 1897, 1904, 1927, 1928, 1929 and 1930 of bryozoan material from the northeastern part of the bay, from Hudson strait, and from the region about Port Churchill in Manitoba, show seventy-five species and well marked varieties, including two species described as new, Bugula simpliciformis and Callopora ungavensis, with one striking variety, Gemellaria loricata var. cornuta.

The comparative poverty of the micro-crustacean plankton in general and the absence of Temora longicornis in particular may afford a partial biological explanation of the paucity of fish-life in Hudson bay. The plankton as a whole is of a mixed arctic and boreal type.

The present study is based on examination of six collections of fishes (about 4000 specimens) from the Hudson bay region made between 1919 and 1930. The material consisted of 45 different forms, belonging to 42 species, 34 genera and 17 families.No endemic species are known from this area. The following subspecies are described as new: Ammodytes dubius hudsonius, Gymnocanthus tricuspis hudsonius and Lycodes reticulatus hacheyi.Sixteen fresh-water and brackish-water forms collected in the Hudson bay area are the same as those that occur in the Great Lakes and St. Lawrence regions.Twenty-eight marine species are known from the region under consideration; the majority of them (22) are truly arctic forms.Two species (Gymnocanthus galeatus and Liparis cyclostigma) previously known only from the north Pacific and Bering sea are found in Hudson bay.The most important commercial fishes are principally anadromous and rarely marine.

Ecological Differences

Cabo Frio, with its unique oceanographic conditions, is an important biogeographical transitional region between tropical and sub-tropical waters. This is due to the presence of upwelling from the Central Water of the South Atlantic (CWSA), and the presence of tropical waters from the Brazilian Current (BC) and Coastal Water (CW). The intertidal barnacle, Tetraclita stalactifera, and its brooding stages were analyzed to correlate environmental conditions with reproductive development. Two thermal contrasting sites were chosen: Ponta da Cabeça (PC), which is under the influence of seasonal upwelling, and Ponta da Fortaleza (PF) which experiences tropical influences. At each site, T. stalactifera specimens were collected monthly and their egg lamellae conditions classified into stages from 0 (empty) to IV (ready to release). Our results show a seasonal effect on brooding at the PC site and a continuous development at the PF site. Nauplii larval availability also followed this trend. Differences between the sites could be due to ecological differences related to water temperature and the ecological-physiological response of the barnacles to these differences.
