Packet 4: Tossup 10

Overlap between two of these entities can be quantified using Schoener’s (“SHOW-nur’s”) D. Machine learning methods for these entities’ namesake modeling in biomod2 often use pseudoabsence data, while the program MaxEnt uses maximum entropy (10[1])methods to model these entities from presence-only data. A sum over the reciprocal of the square of proportions gives Levins’s measure for the breadth of these entities. (-5[1])The apportionment of these things (10[1])was analogized to breaking a stick by Robert MacArthur. These constructs were defined as n-dimensional (-5[1])hypervolumes (10[2])by G. E. Hutchinson. Due to competition, (10[1])organisms occupy (10[2])the realized (10[1])form (10[1])of (10[1])these (10[5])entities (10[2])rather (10[1])than (10[1])their fundamental form, often after partitioning these things (-5[1])to avoid competition. (10[2])For 10 points, name these ecological constructs, the roles and positions that species have in their environments. ■END■ (10[3])
