Stability and Complexity in Model Ecosystems
Stability and Complexity in Model Ecosystems is a landmark 1973 book by theoretical ecologist Robert May that uses mathematical models to challenge the assumption that more complex ecosystems are inherently more stable.

Unified Neutral Theory of Biodiversity and Biogeography
Unified Neutral Theory of Biodiversity and Biogeography is an influential ecological theory proposing that biodiversity patterns and species abundances can be explained by assuming ecological equivalence among individuals regardless of species.

D.
The niche: an abstractly inhabited hypervolume
"The niche: an abstractly inhabited hypervolume" is a seminal ecological paper by G. Evelyn Hutchinson that conceptualizes an organism’s niche as a multidimensional space defined by environmental conditions and resources.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
