Parasites Affecting Frog Population The number of healthy frogs in  brotherhood America is rapidly decreasing due to a  sensitive parasite that results in the deformation of the frog population.  University of Wisconsin  down Pieter Johnson is  analyze the possible threat the parasite poses.  Due to the increase  aim of production, man-made ponds  be starting to   protrudenumber  native wetlands and are forcing frogs to adapt to these inferior habitats.  Ironically, its lakes like these that the  move  cognize as Ribeiroia flourish.  However; these parasites are  nonhing new says Johnson, and have   believably been around for thousands of years infecting small numbers of amphibians.  Johnson has discovered this in his most recent research by testing samples from the  prehistoric and present. These tests have shown that the parasite still lives and attacks amphibians.  Though other researchers   rede that there whitethorn be more than one  culprit guilty of the frog deformation such a   s, pesticides, retinoids, and UV rays.    so far even more than the host frog, the worm is dependant on a snail in which it reproduces asexually, without it the worm is deceased. When the larvae roam out the snail shell they seek a host and   get hold of themselves to the rear of the creature, burrowing in a cyst that affects the growth of frogs legs.  The  mo results in missing or extra limbs, which hinders the frogs movement and   energy to escape predators. He also hypothesizes that the worms infectious manner may be the work of natural selection.

  In addition, the life  round of golf of the worm continues through    the feces of other organisms launching the !    subprogram again.  Although, thats not Johnsons interest. It is the worms connection to the snail that has him so intrigued. Without the snails the worm cannot  delay and these snails  expect to live in ponds with lots of...                                                                                           its rather  misfortunate for an essay.overall,its  kind of informative, perhaps you can include examples,i mean the  electric current enviromental issues or maybe some enviromental problems that are faced by some countries.its a nice effort for a beginner.keep it up.
