Ecology and environmental protection, flora, founa and on landNurlan1989
Ecology (from Greek: οἶκος, "house" or "living relations"; -λογία, "study of") is the scientific study of the distributions, abundance and relations of organisms and their interactions with the environment.Ecology includes the study of plant and animal populations, plant and animal communities and ecosystems. Ecosystems describe the web or network of relations among organisms at different scales of organization. Since ecology refers to any form of biodiversity, ecologists research everything from tiny bacteria's role in nutrient recycling to the effects of tropical rain forest on the Earth's atmosphere. The discipline of ecology emerged from the natural sciences in the late 19th century. Ecology is not synonymous with environment, environmentalism, or environmental science. Ecology is closely related to the disciplines of physiology, evolution, genetics and behavior.

Endothelin peptides Endothelin-1, a 21-amino-acid peptide, is the predominant isoform of the endothelin peptide family that includes ET-2, ET-3, and ET-4 Endothelin-1 is produced primarily by endothelial cells but can also be synthesized by vascular smooth muscle cells (VSMCs) and by macrophages The action of ET-1 are mediated by 2 receptor subtypes, ETA and E TB receptors
