Though the ocean seems like a very quiet place‚ but if listens carefully‚ one might just hear the sounds of the fish choir. Most of this undersea music comes from soloist fish‚ reiterating the same calls again and again. But when the calls of different fish ………………….co existed ‚ coincide ‚combine‚ mingle with this‚ they form an ensemble. Robert McCauley and his counterparts of Curtin University in Perth‚ Australia‚ discovered seven definite fish choruses‚ occurred mainly at dawn and at dusk ; by recording

For this assessment‚ discuss a variety of techniques used to stabilize shorelines throughout the world. Then answer this question. “Are they temporary or permanent?” Then let’s discuss‚” Two ways in which the development/urbanization of coastal areas contribute to shoreline erosion‚ and what they contribute to our beaches?”‚ also‚ “What increases with the creation of roads and rooftops?” Shoreline erosion is a big expensive problem that is having a negative impact on our environment.

I personally selected a maroon clownfish with two anemones. I also chose 5 sergeant majors‚ 2 bleenies and a yellow tang. 2. What changes did you make to your reef tank during the 12 weeks and why did you make them? After I selected my fish‚ I noticed that the tank

The Mytilus californianus: The Larvae’s Ecological Niche a Trade-offs of becoming an Adult Marine organisms that have a larvae stage dependent on wind waves to move and settle in an environment‚ where they develop to adults and recruit. The Mytilus californianus has a larvae stage and as the waves break into the surface of the pier pilings in Santa Monica‚ the larvae stick to the hard substrate that the vertical columns provide. The random placement of the larvae on the pier piling is what determines

Loggerhead turtles have many significant adaptations to their current and past environments. Turtles of the family Cheloniidae have various morphological adaptations for aquatic life. Early turtles lost the capacity for aquatic propulsion by body and tail undulations when they developed a shortened‚ more rigid body form during the Triassic‚ as an adaptation for armored resistance to attack by predators. However‚ terrestrial body form with a carapace and walking-type limbs precluded aquatic locomotion

Imagine yourself diving in the ocean‚ as you get deeper and deeper the water gets colder and colder soon you reach the bottom of the ocean this part is called the Abyssal zone. You can’t see anything the water pressure is very powerful. You begin to wonder how the animals can live down here. In order to survive this ecosystem organisms must have adaptations. An ecosystem is the habitat or environment an organism lives in for example the ecosystem of the dumbo octopus is the abyssal zone. There

Investigating the Control Dynamics of an Algae-Brine Shrimp Ecosystem 113437768 Introduction The purpose of this lab is to investigate whether an ecosystem consisting of marine algae and brine shrimp are controlled by top-down or bottom-up mechanisms. The terms top-down and bottom-up in the context of ecology describe which trophic levels are enforcing population pressures on the others. Thus‚ the top-down mechanism of control holds that consumers are responsible for determining the abundance of
