Ecological communities consist of multiple species, which form a food web and compete for habitat and biotic and abiotic resources. Populations of individual species fluctuate pending resource allocation and fitness, and interact with other community members in a variety of ways. Intraspecific competition and interspecies interactions shape phenotypic characteristics and exert selective pressure on all individuals leading to adaptations of populations.
Consider an ecological community in your local biome, and focus on interspecific or intraspecific interactions. Which species are likely to have a great influence on another species in the community? Describe three interspecies interactions , then select one for in-depth discussion. How do community characteristics shape species interactions and how would you study and test if co-evolution occurred?
