Connections per node -This is a simple average of the number of flows from one node to another. In our example, we have 10 links and 6 nodes. The average connections per node is 10/6 = 1.66. Even very complex food webs might only have 2 connections per node.
Longest direct distance - By inspecting the network, determine which two nodes are furthest apart and how many connections it takes to tie them together. In a network of 6 nodes the furthest any two nodes could be from each other is 5 links. In the example lake network shown above, the central role of the surface water and metalimnion reduce this distance to only 3steps; the shortest distance from stream1 to the hypolimnion is 3 links.
Connectivity - The connectivity is the number of links as a porportion of the theoretically possible number of links. In this approach I am not allowing internal links (for example from stream1 to stream1) which means that the number of possible links is (number_of_compartments)*(number_of_compartments -1). In our example this is
10 links /(6*5) = .33
