Paige Sprague Diversity of Life NRM 2307 Benefit of the Doubt (Article at bottom of page) Fishless Lakes The article I read describes the great variety of life one can find within fishless lakes. Although this may seem inaccurate to some, biologists have found otherwise. Teaming with life, these lakes support tremendous biodiversity. Some argue fishless lakes are actually destroyed by added fish for recreational and other use instead of improving upon them because the lakes become more useful to humans. These lakes play important roles for supporting amphibians as well as other organisms. It was interesting how these concepts related to the material covered in biodiversity. Scientists have studied fishless lakes and found these bodies of water teaming with life. Insects and amphibians are abundant and thriving. Many species survive here that are not subjected to predation from fish. This variety is somewhat lost among fish-stocked lakes. The fish prey on insects and amphibians so the lakes are not as abundant in those types of species. This article applied to what we have been learning in class. Each species fills a niche in their habitat. Fish out compete many invertebrates and other organisms. This is why the biodiversity is so great in these fishless ponds. There are so many niches to fill without fish that multiple species can coexist and survive. I also

Paige Sprague Diversity of Life NRM 2307 Benefit of the Doubt (Article at bottom of page) believe it is important to try to keep these fishless habitats intact as much as possible without disturbances from humans trying to stock these lakes. If fish come into fishless lakes, many organisms will not survive. We must understand this to protect biodiversity. On a Hunt for Fishless Lakes, Teeming With Life  By MURRAY CARPENTER Published: April 27, 2009 WASHINGTON COUNTY, Me. — Many people scour the Maine woods for  lakes with big trout, but just a few seek places like this unnamed four-acre  lake near the Machias River. Like thousands of other Maine lakes, it is scenic  and remote, but it claims a rare distinction: it has no fish.    Enlarge This Image

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
