1 Renal failure may cause pulmonary edema as the kidneys are unable to filter out toxins in the blood. 2  Smoke inhalation may cause severe inflammation of the lung tissue, which results in fluid accumulation in the lungs.  Lymphatic insufficiency result in inadequate drainage of lymph fluid.
Phylogenetic trees are constructed in a variety of ways to summarize the evolutionary relatedness of different organisms. The data represented in a phylogenetic tree may come from (but are not limited to) observations of an organisms anatomical features and/or molecular sequence information.ladistic analysis orders organisms along a phylogenetic tree in branches, and describes the extent of divergence between the branches. If the analysis is based on a molecular sequence alignment, two major computational approaches may be employed in order to construct a tree:
Phylogenetic diversity takes those lengths to give you an idea of how evolutionarily diverse the fauna in your ecosystem is and to give conservation people priorities. For example, long branches mean that you have basal taxa which are more important to conserve because they originated earlier and thus have more information about evolution to give. On the other hand, very short branches tell us that these species are very new, possibly the result of an adaptive radiation and are also in need of protection.
