PROCESSES IN MANGROVE ECOSYSTEMS II PROBLEM SET 1. BIOLOGICAL INTERACTION During our Field Trip to the Cairns Airport Mangrove Boardwalk on 7th August‚ 2013‚ I observed a distinct distribution pattern in the locations of the Orange-Clawed Fiddler Crabs (Uca coarctata). Upon further investigation‚ I noticed that the larger males of the species (easily identifiable as those with one large claw) colonised the open areas located beside the Middle Creek viewing platforms‚ that were in full sun for

and osmotic concentration. Body fluids are denser than water which has a specific gravity of 1‚ plus solutes. Through the examination of the two organisms‚ P. lurca is an osmoconformer and U. coactarta is an osmoregulator. Introduction Osmoregulation is the physiological process that all organisms of any habitat use to maintain their water balance and internal salt for several different reasons such as‚ compensating for water loss‚ avoiding excess water gain‚ and maintaining a proper osmotic

Osmoregulation is the active regulation of the osmotic pressure of an organism’s fluids to maintain the homeostasis of the organism’s water content; that is‚ it keeps the organism’s fluids from becoming too diluted or too concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis. The higher the osmotic pressure of a solution‚ the more water tends to move into it. Pressure must be exerted on the hypertonic side of a selectively permeable

Osmoregulation is the regulation of water and ion concentrations in the body. Keeping this regulation precise is critical in maintaining life in a cell

Osmoregulation as a Homeostatic Mechanism using the Comparitive Melting-Point Method for two Crab Species. Abstract Two crab species‚ Plagusia and Cyclograpsus‚ were collected from a local estuary in the littoral and deep water zone for osmoregulation studies. To examine differences in osmoregulatory mechanisms among the species‚ haemolymph of the specimens was extracted once they were acclimated to varying concentrations of seawater. Using the comparative melting-point‚ capillary tubes were

Fiddler on the Roof was a moving yet highly entertaining musical about a Jewish family living in Russia during the early 20th century. This book musical allows the audience to embark with Tevye‚ the father‚ and the rest of his family on the journey that is life.
