Endangered Species Act

The Endangered Species Act (ESA) was passed into law on the 28th December 1973. It was enforced by the United States of America to protect critically jeopardized species from extinction, from a consequence of development and economic growth and the conservation of the environment they depend on. There are two main federal agencies that are administered to the act: the United States Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration (NOAA). A species is considered...

Reanimate Extinct Species?

Reanimate address is that we can revive species that could possibly help our ecosystems and save modern day species of animals from going extinct; but on the other hand, reviving “extinct species poses a risk of selling the public on a false promise that technology alone can solve our ongoing environmental woes.” Reviving certain species could give ecosystems that depend on “keystone species” that have lost the species diversity they once had because some species no longer fit. And as environmental...

Prairie Dogs

“Prairie dogs have a significant effect on biological diversity in prairie ecosystems. More than 200 species of wildlife have been associated with prairie dog towns, with over 140 species benefitting directly…” (Williams 34). Terry Tempest Williams, author of the book “Finding Beauty in a Broken World,” delivers a strong argument as to why prairie dogs should be protected. Prairie dogs contribute to the welfare of animals around them in many ways. They create diversity, kinship and community. Williams...

Seagrass in Talavera, Taganaan Surigao Del Norte, Philippines

Quadrats measuring 1m x 1m were sampled at 10m interval within the transect line. Seagrass and seaweed cover inside the 1m2 quadrat were scored based on percentage cover for each species. A GPS (Global Positioning System) position reading was taken at the beginning and end of each transect for later relocation. Data on the species composition and relative abundance of seagrasses and seaweeds were obtained along three transects about 100 meters long. Estimates of percent cover of seagrass and seaweeds...

Lab Report Biodiversity

INTRODUCTION Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem...
