Coral Reefs Essay

Our findings reveal that there is no significant difference in abundance, sex distribution, or size distribution among the highly populated site, the partially populated site, and unpopulated site (p-values are all <0.05). Therefore, we cannot support our alternative hypothesis that increased human presence results in the decreased presence, decreased size, and skewed sex ratio of sand crabs. As a result, we accept our null hypothesis that the amount of human presence has no significant effect on

Evaluation of microsatellite cross amplification for population genetic study of Caribbean Sharpnose shark Rhizoprionodon porosus (Carcharhinidae) in Colombian Caribbean. The Caribbean sharpnose shark, Rhizoprionodon porosus is an important resource for artisanal small-scale fisheries. It is one of the most abundant coastal sharks within its distribution range, and plays an important role as a predator in coastal marine ecosystems. For its coastal habits, it is susceptible to intensive extraction

The United States of America’s west coast is home to a diverse population of aquatic creatures. Amongst those sea-dwellers is a kind of mammal called a California sea lion. The website Scientific American has published an article on how the amount of naturally occurring algae in the California sea lions’ habitats has reached an all-time record high in 2015. Though one may not see algae as a necessarily bad thing, when grown in excess amounts, the toxins in algae can accumulate and cause harm to the

I understand why you may think sea stars are not important, however they are a keystone species and essential in their environment. If you are not sure what a keystone species is, it is a species that has a key role in sustaining the life of other organisms in an economic system (Ferrer, 2015). Many species of the rocky intertidal communities depend upon the sea star. Sea stars feed on sea urchins, which control the population. Without sea stars all other organisms would vanish except for mussels

of some of them, this list will surely provide you with some facts about them you didn't know. So read on to learn more about the strange and wonderful animal life on our planet! Number Five: The Blue Parrotfish This tropical fish is found around coral and is a strange shade of florescent blue. The fish eats only tiny organisms - algae is one of its main sources of - and therefore spends almost all of its life searching for things to eat. Number Four: The Liger Yes, it really exists (only in captivity

Natural History of Zebra Mussels Invasive species aren’t anything new in Minnesota; however, “over the past 500 years, more than 4,500 species have established populations in the United States” (Benson, 2015). Zebra mussels (Dreissena polymorpha) are one of those invasive species. Named because of their zebra-like stripes, these bi-valve mussels live between 4-5 years and grow to about 50 millimeters. Zebra mussels are native to western Russia near the Black and Caspian Seas. Construction of canals

Reproduction Sea stars can reproduce sexually and asexually. In sexual reproduction, fertilization occurs in the water with males and females releasing sperm and eggs into the environment. The fertilized embryos, which are free-swimming animals, become part of the zooplankton in most species. If they break in half they can produce another Sea Star, which relates to regeneration. Feeding A starfish can eat anything he can fit in one of his two stomachs. They do this by pushing a stomach out of his

Both the passage and the lecture discuss the zebra mussels. While the passage argues that there are many reasons to believe that zebra mussels reached to North of America and cannot control their pollution, the lecturer strongly disagrees with this claim. According to the passage, history of the zebra mussel’s purposes that the invasion made possible by human activities because ships help spread it. As a result, the species will soon colonize all of North America. The professor directly challenges
