Abstract/Description
-
Ecological components such as availability of resources, physical make-up of the environment, and biotic interactions amongst and between species are factors that determine habitat selection and coexistence of organisms within a community. A stable coexistence of species within a community is possible if the limited resources are partitioned to be speciesspecific. However, sympatric species are expected to exploit similar resources. Two species of octopus Octopus vulargis and Macrotritopus...
Show moreEcological components such as availability of resources, physical make-up of the environment, and biotic interactions amongst and between species are factors that determine habitat selection and coexistence of organisms within a community. A stable coexistence of species within a community is possible if the limited resources are partitioned to be speciesspecific. However, sympatric species are expected to exploit similar resources. Two species of octopus Octopus vulargis and Macrotritopus defilippi with similar ecological requirements coexist at an intra-coastal habitat. The ecological phenomena of coexistence of species can be quantified by measuring the ecological components of the niche. The objective of this study is to identify the components that facilitate coexistence. The ecological components being examined include: general habitat location, habitat heterogeneity, foraging and feeding times and locations, and biotic interactions. Global Positioning System will be used to determine the general location of the octopus species den. The importance of habitat heterogeneity will be addressed by looking at substrate make-up of the different species dens. Foraging and feeding times and locations will be recorded to determine any temporal or spatial influence on species coexistence. Field observations and laboratory habitat selection experiments will be conducted to determine what habitat each species selects in the presence and absence of the other species. Our studies will allow identifying ecological components that facilitate coexistence of sympatric species, provide insight to cephalopod ecology, and conservation at a heterogeneous environment, which is of importance to maintain marine biodiversity and ecotourism in south Florida.
