Introduction Invasive species are continually documented as a major risk to ecosystem health and worldwide biodiversity. Invasive marine fish introductions are still considered relatively rare and historically the environmental effects are often discounted. This is different from historically famous invasive species such as the zebra mussels in The Great Lakes, which caused well-documented harmful economic and environmental effects. While these are considered rare, they have been documented,…

Some of the most phenomenal sites that rest on this planet, lie in the most bizarre places. One of the most astonishing sites that I have ever seen, rests on the coast of the tiny island Culebra. The basic description of it is a gathering of rocks that enclose a small area but really it is so much more. It lies just a few feet away from a waterfall, so in between the creases of the rocks, water can seep in, thus resembling a pool. Although the best part was, when the hot summer air mixed with…

INTRODUCTION Parental care in Decapoda is usually limited to the female's care for her eggs (i.e., carrying, oxygenating, cleaning, protecting, and sometimes assisting in hatching) (Hazlett, 1983). Care of recently hatched juveniles is rare in invertebrates, and evolved mainly in terrestrial and freshwater species (Thiel, 2000). The freshwater crayfishes show some of the most complex patterns of parental care among decapods (Hazlett, 1983). The majority of studies with these animals refer to…

Defeo, McLachlan et al examine what makes sandy shoreline habitats unique among other types of shorelines. Their article looks at threats to beaches, from weather patterns, to extreme storms, as well as man made structures and failed attempts at beach rehabilitation. The article makes a point that long-term information about the on-going changes in beach habitats is often hard to come by, and what information can be found is very short-term, geologically speaking. They suggest that in order to…

The reading material and lecture discuss several theories about ways that agnostids live. The writer presents several theories including free-swimming predators, seafloor dwellers and parasites. However, the professor put forward three reasons that directly contradict the theories and effectively prove that they are not persuadsive and somewhat inaccurate. First of all, the writer suggests that agnostids can swim freely in the ocean. By contrast, in accordance with the professor, this veiw is…

The three-spined stickleback (Gasterosteus aculeatus) is a species of fish that exhibits a wide range of morphological variation within its subspecies, which typically fit into two categories, anadromous (spawn in freshwater, migrate from saltwater) and freshwater varieties. Saltwater marine varieties of the fish typically have two dorsal spines, along with a pelvic spine. These spines, as studies have shown, act as a defense mechanism against soft-mouthed predators, by increasing the diameter…

Do you know that there are almost two million marine species are estimated to exist in the ocean? Ocean, or marine, is the hometown of some of people. But we are still discovering and learning this familiar and unfamiliar biomes. The location, temperature, characteristic and dwellers are quite differ with other biomes on the earth. Ocean is the biggest part on the earth. There 71% of area on the earth have been covered by the ocean. The ocean entailed the 97% of liquid on the earth. “The oceans…

Radium Springs is an Unincorporated community that is located in the coastal plain area which is right below the piedmont region. The exact location of the Radium Spring is Southwest on the outskirts of Albany Georgia in Dougherty county. The Radium spring is one of Georgia’s seven wonders and the largest natural artesian spring in the state of Georgia. The formation of this spring is due to the karst topography where the surface of the water infiltrated the earth crust surface that became the…

of Norway and Southeast of Greenland, and Urates Barents Sea with coastal waters of Northern Norway, along with waters that merge the Taroe Islands, southwest of North Sea. The size of the Norwegian Sea, stops where it ends, with surface area of 1,380,000 sq. Km, although size is questionable. “Average depth runs 1,700 meters (5,577 ft.), while the maximum depth of North Sea has been measured at 3,970 meters (13,020 ft.)” (www.WorldAtlas.com). The Norwegian Sea, Norway and United Kingdom, have…
