Healthy marine ecosystems provide critical benefits to people worldwide, but increasing threats from climate change and human activities disrupt ecosystem functionality and put these benefits at risk. Local and regional assessments have shown these i

where d is any metric on M compatible with its topology. If x is a hyperbolic periodic point of f, the stable manifold theorem[7] implies that then W”(x) and W”(x) are 1-1 immersed Euclidean spaces. An f f Diff M is Morse-Smale iff: (1) Q(f) is f

For a regular closed curve on the plane it is known that E = I + X + 1 2 F E = I + X + \tfrac {1}{2}F where E, I, X and F are the numbers of external double tangents, internal double tangents, self-intersections, and inflexion points respectively. It
