Species

global scale. Scientists have predicted that “50 percent of all species may be lost during the 21st century” ()unless some effort to protect animals from extinction is made. In fact, an impact at this scale could interfere with the worlds growing population effort to feed and heal its…

RELATIONSHIP BETWEEN SPECIES DIVERSITY AND SIZE Effect of Surface Area on the number of species in biodiversity. Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be. Species diversity is the variety of organisms that make up a community It has two components: • SPECIES RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain…

Invasive species are a problem both economically and environmentally. One example of an invasive species is the zebra mussel. In this essay you will learn what the zebra mussel is, why we don’t want it in Iowa, and how this invasive species is being controlled. The zebra mussel is a freshwater mollusc. It is the size of a fingernail, but can grow up to two inches. Zebra mussels get their name from the striped pattern that appears on them. The zebra mussel has a D-shaped shell. It was introduced…

Invasive Species “Invasive species are one of the leading threats to native wildlife and approximately 42% of threatened or endangered species are at risk primarily due to invasive species” (National Wildlife Federation, 2016, p.1). 1. What kinds of problems can invasive species cause? Do you think one group of invasive species is worse than another? Why, or why not? Some of the problems that invasive species cause is impacting natural ecosystems, the economy, recreational, agricultural,…

estimated that every day we lose 150-200 species from this Earth. Of the 44,838 species that have been assessed, 16,928 are listed as endangered, meaning they are threatened with extinction. The rest of the estimated 8,700,000 species on Earth have yet to be assessed, so the number of threatened species is significantly larger than the current estimate. In the 1970s, many environmental laws were passed to curb the mass extinction of species including the Endangered Species Act of 1973 or ESA.…

I came across this article, talking about how they might under new legislation might get right of the Endangered Species Act all together in the future, and this was appropriate since we have been talking about endangered species in class this past week. There was many reasons I thought this article was credible, one of them was it was quoting different stories from “The New York Times,” a newspaper that has reliable information on this topic. It is also talking about different congressman…

Keystone species are the main primary driver for diversity. Keystone species are species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. They cause biodiversity for 3 reasons. First, the keystone species causes the different animals from all around that area to come to where the keystone species is located because the keystone species has what the other species need to survive, a working ecosystem . These animals then…

The Endangered Species Act is the most successful and important conservation act in the United States of America. More than 2,000 plants and animals are protected under this act and 93% of these species have remained stable since they became protected under the ESA. The Endangered Species Act is administered by two federal agencies, the United States Fish and Wildlife Service and the National Oceanic and Atmospheric Administration. The ESA has helped prevent some of our most beloved creatures…

Non-native invasive species have caused conservationists and ecologists to stew. In simpler terms a non-native species is a species that is an alien to an environment, but will not cause danger. Invasive species are species that causes harm. More specifically, a non-native invasive species are a particular type of species that are foreign to an environment and causes risk towards that particular environment. Non-native invasive species, invasive species and NNS will be used interchangeably.…

non-native species are species that have been introduced into an area or region that is not their normal habitat or environment. These species are sometimes very invasive and will take over the areas that they inhabit. There can be very negative effects from the introduction of non-indigenous species into certain environments. The ecosystem of an area is likely to be compromised from certain aggressive and invasive species. The lionfish is one of those. The Lionfish Invasion Native species are…
