Legal trapping season for the Newfoundland marten has been closed since 1934. [6] However, accidental mortality of the Newfoundland marten in snares continues at a rate of 1.45 marten per year since 1970, which out of 300 individuals is too high as well as the possibility of unreported kill. [15]
South Avalon-Burin oceanic barrens is a taiga ecoregion located within the Canadian province of Newfoundland and Labrador and the French overseas collectivity of Saint Pierre and Miquelon. It is defined by the World Wildlife Fund (WWF) categorization system as inhabiting the southern headlands of the Avalon and Burin Peninsulas along the ...

Stage 1 (3.85–2.45 Ga): Practically no O 2 in the atmosphere. Stage 2 (2.45–1.85 Ga): O 2 produced, but absorbed in oceans and seabed rock. Stage 3 (1.85–0.85 Ga): O 2 starts to gas out of the oceans, but is absorbed by land surfaces and formation of ozone layer. Stages 4 and 5 (0.85 Ga–present): O 2 sinks filled, the gas accumulates.

A marten is depicted on the obverse of the 1-, 2-, and 5-kuna coins, minted since 1993, and on the reverse of the 25-kuna commemorative coins. [16] With adoption of euro as the national currency in 2023, a marten continues to be depicted on the obverse of the Croatian 1 euro coin .
In the presence of disease or other conditions that change the hemoglobin oxygen affinity and, consequently, shift the curve to the right or left, the P 50 changes accordingly. An increased P 50 indicates a rightward shift of the standard curve, which means that a larger partial pressure is necessary to maintain a 50% oxygen saturation. This ...
Open ocean areas with no oxygen have grown more than 1.7 million square miles in the last 50 years, and coastal waters have seen a tenfold increase in low-oxygen areas in the same time. [34] Measurement of dissolved oxygen in coastal and open ocean waters for the past 50 years has revealed a marked decline in oxygen content.
The Martin curve is a power law used by oceanographers to describe the export to the ocean floor of particulate organic carbon (POC). The curve is controlled with two parameters: the reference depth in the water column , and a remineralisation parameter which is a measure of the rate at which the vertical flux of POC attenuates.
