The Habitat Of Southern Toads - 1349 Words

Abby Buren, Sheridan Dillon-Robinson, Amber Hancock, Brett Shannon Identifying the preferred habitat of southern toads Introduction St. Andrews university is a 500 acre campus consisting of many aquatic habitats, ideal for amphibians such as frogs and toads. Amphibians are susceptible to changes in the environment and are indicators of environmental diversity and success as well as identifiers of pollutants in the environment (Marshall, 2013). We were interested in the prefered conditions for local toad and frog species on St. Andrews campus, located in Laurinburg, North Carolina. Some aquatic environments include lakes, ponds, creeks and a Carolina Bay. We hypothesised that toad and frog populations will be denser at the Carolina Bay because the area provides acoustics, ideal for calling mates and also has a lot of surface area that allows for solar heating that increases metabolism that would allow for quicker development (metamorphosis) as well as having lots of areas to lay eggs, due to mating and offspring developmental requirements. Frogs and toads are external fertilizers and the females lay their eggs in the water and the males fertilize the eggs. Also, once the eggs hatch depending on the species they will spend the first month or so of their lives in water as a tadpole until they metamorphosize into frogs or toads. Due to this, they are more likely to be in aquatic areas during mating seasons (Partymiller, L.). Out of the many toad and frog species in the area, weShow MoreRelatedThe Effect of Pesticide Runoffs on the Everglades975 Words   |  4 Pagescultivation of sugar cane just to mention one of those responsible and creates a loss of natural habitat, water pollution, and threatens existence of wildlife. Many pesticides are not easily degradable; they persist in soil, leach to groundwater and surface water and contaminate wide environment. The loss of natural habitats. This is a very critical situation that needs to be fixed urgently. The habitats of the Everglades depend on an annual water cycle which has been hindered by the developmentRead MoreFrog Extinctions as Indicators of Environmental Problems Essay1863 Words   |  8 Pagesextinction. In most cases when I look around some ponds and creeks, I find that something is missing: frogs. One of the species near extinction is the Monteverde harlequin frog mainly found in the Costa Rican Mountains (â€Å"Why the Frogs Are Dying†). The Southern Yellow-legged frog and the Sierra Nevada Yellow legged frog populations have declined by 95-98 % even in highly protected areas such as the Yosemite Park (University of California - Berkeley). The massive world-wide decline of frogs can best be understoodRead MoreWhat I Visited The Newport Back Bay Visitors Center1428 Words   |  6 Pagesintricate Back Bay, how it is being preserved, and how you can help. Plants and Animals The Back Bay has a very large variety of plants and animals. Each of the plants or animals is specifically adapted to their particular habitat in which they grow. There is a large diversity of habitats ranging from salt water to fresh water, or both in an estuary, hot desert areas, and more. In the saltmarsh the plants found are called halophytes.

The vernal pools (Picture #4) are a part of the grasslands and marshes biome. Most of the pools are found in the central valley but also in the inland valleys of the inner Coast Ranges, and along coastal terraces of Southern California. They are temporary pools of water that are usually without fish, and thus allow the safe development of natal amphibian and insect species. Most pools are dry for at least part of the year and fill with the winter rains or snow melt.Read MoreThe Survival of the Rock Hyrax in Urban Areas 3185 Words   |  13 PagesRATIONALE Urbanisation poses a threat to wildlife through habitat destruction and population fragmentation. As a consequence, urbanisation alters the distribution of species. Yet, urbanisation creates opportunities for some species to thrive and persist in the urban jungle. Many species have adapted to urban areas across the globe. However, not all animals living in urban areas adapt to urban life and instead might be confined to refugia that match the pre-existing adaptation to natural conditionsRead MoreEssay about Why We Should Stop Extinction2515 Words   |  11 Pages or jaguar, may no longer be hunted in the countries where they are indigenous, and many other countries forbid their importation (Miller). Another example of an animal being hunted to near extinction is the whaling industry in the 19th Century. Southern Right Whales were hunted because they float when dead, can yield, many barrels of oil, have long baleen plates and come close to shore. Whale oil was used for candles, ligh t fuel, soap, heating and lubricant.

Another aspect of the tundra includes the vegetation that is found there and the adaptations that have been made. The tundra is known for its’ cold temperatures, but also its’ limited plant species.
