Ecologists study the organization and function of communities from the scale at many spatial and temporal scales. Communities are complex systems that can be characterized by community structure (the number and size of populations and their interactions) and community dynamics (how the members and their interactions change over time). Scientists study ecology at the community level to understand how interactions between species and
