1."Lizard communities in Antigua consist of varying combinations of three species: Anolis leachi, Anolis wattsi, and Ameiva griswoldi. Depending on the species present, Anolis wattsi habitat use and relative abundance will vary substantially. The relative importance of factors such as interspecific competition and intraguild predation are being evaluated in these communities. " In the islands of the caribbean, they found 9 genera of parasites these including, nemotodes,digeneans and acanthocephalan. The dry islands tended to have fewer of the species but mostly all of them had them, or at least one of them, this including Antigua and Barbuda. There is no evidence found that these parasites affect their host survival, so this could be specified as a commensalism relationship too. In Antigua and Barbuda there are common predator-prey reltationships, for example they have a lot of birds, these birds eat the fish in the ocean surrounding the islands. Bird being hte predator and the fish being the pray. They have much of hte same predator-prey relationships as we do, just maybe with some different animals. For mutualistic relationships, there are some, more of the common ones however, such as pollination. With the bee and the flower both benefitting from the relationship. They also have soem in the waters surrounding the islands such as the clown fish and sea anenome.

2.I dont know for sure if these species live in clumps or populations but i would say population due to how small the islands are, there arent much of the species so it would be in my mind just one big but small population. i did find however a certain tree that occurs in clumps in english it is called Baobab, or i guess sometimes called a lemonade tree. 3.Since these islands are in the tropics and on islands there are a lot of reptiles present. Reptiles on these islands show signs of both r and k selected species. For example lizards more so the smaller ones are r-selected becasue they have short life spans they dont parent their young and they reach maturity after a year. However the bigger lizards tend tohave some k-selecected characteristics too, but i would stay still are r-selected. Birds on the other hand, whcih are very popular on the islands are k-selected, they have few offspring, they are well parented, so they are definatley competitors. Fish in the ocean around teh ocean are r-selected like the lizards because they have shorter life spans, have a lot of offspring and dont parent their young. THose are just a few of the r and k selected species. 4. Antigua Barbuda have mostly Primary Succession due to them being an island and being surrounded by water. They are going to be starting from scratch-the rock by the sea and gradually change in environmentla composition over time so that the ecosystem is set and species can move in. 5.i would say antigua and barbuda are more likely to have a high inertia and a low resilience, because if they were hit hard i feel they wouldnt have the high resilience of getting up and restoring it right away, it would take awhile.
