Prostacyclin's interactions in contrast to thromboxane (TXA 2), another eicosanoid, strongly suggest a mechanism of cardiovascular homeostasis between the two hormones in relation to vascular damage. Degradation. Prostacyclin, which has a half-life of 42 seconds, [5] is broken down into 6-keto-PGF 1, which is a much weaker vasodilator. Mode of action
There is one species of Otter on the low risk list which is the Oriental Small Clawed Otter. Several of the species though are listed as vulnerable and endangered. They include the Southern River Otter, Hairy Nosed Otter, Giant Otter, and the India Smooth Coated Otter.In the United States Otters are protected under the Endangered Species Act.This is due to the fact that the conditions they live under could be compromised easily and that could lead to a significant reduction in their numbers in very little time.tters Conservation Status. Many of the different species of Otters have been heavily hunted in the past. As a result the numbers of them are quite low. This is why conservation efforts are in place to help them continue to survive. The main reason that these Otters were hunted though was for their fur.
The IUCN Red Book lists the four species of tapirs (Tapirus bairdii, T. terrestris, T. pinchaque and T. indicus) as either vulnerable or endangered. The Mountain tapir, T. pinchaque, is one of the most endangered large mammals in the world.The Bairdâs tapir, T. bairdii, is the largest land mammal in the Neotropics and also endangered. The Malayan tapir, T. indicus, is the only Old World extant species and is also endangered in Sumatra and mainland Malaysia.apirs are herbivores best suited to primary or old growth secondary forest, and their reproduction is slower than most mammal species due to a long gestation period (13 months) and to the fact that there is only one offspring per gestation. Tapir Habitat Range. Note that ranges are an illustrated approximation.
