Introduced species have had a drastic effect on Australian agriculture’s production and economy‚ and continue to pose an ever-growing threat. Invasive plant species are highly adaptable‚ resistant to control and spread aggressively. Methods of controlling these invasive species can often be expensive‚ time-consuming and controversial. Introduced plants can have drastic effects on natural ecosystems by smothering native vegetation‚ degrading creeks and rivers‚ and spreading diseases. Sometimes introduced

Biology‚ Phylogeny‚ and Ecology of the Stomatopoda Stomatopods‚ also known as mantis shrimp‚ are an ancient group of marine arthropods that belong to the class Stomatopoda. There are approximately 350 species of stomatopods that have been discovered to date‚ ranging in size from 1 to 30 cm. (Caldwell 1975) Stomatopods are a group of crustaceans that belong to the class Malacostraca‚ along with familiar crustaceans such as crabs‚ lobsters‚ and shrimp. The malacostracans are defined by their unique

INSECTIVOROUS PLANTS An insectivorous plant‚ also called a carnivorous plant‚ captures prey items‚ such as insects‚ spiders‚ crustaceans‚ mites‚ and protozoans‚ as a nitrogen source. Many insectivorous species live in freshwater bogs‚ where nitrogen is not present in available form‚ because the pH of the water is extremely acid. The forms of entrapment by these types of plants are modified leaves. Five basic trapping mechanisms are found in carnivorous plants. 1. Pitfall traps (pitcher plants)

The number of lymphocytes in the GALT is roughly equivalent to those in the spleen‚ and‚ based on location‚ these cells are distributed in three basic populations: 1.
