A niche‐based theory of island biogeography
Ecology and Evolution, 2023 The equilibrium theory of island biogeography (ETIB) is a widely applied dynamic theory proposed in the 1960s to explain why islands have coherent differences in species richness. The development of the ETIB was temporarily challenged in the 1970s by the

Theory choice as niche construction [PDF]
, 2023 We focus on a neglected aspect of scientific theory choice: how the selection of theories affects epistemic values. Building on Kuhn, we provide a general characterization of the feedback-loop dynamic between theories and values in theory choice as analogous to the relationship between organisms and the environment in niche construction.

Spatial distributions of niche-constructing populations [PDF]
Computational Ecology and Software, 2015 Niche construction theory regards organisms not only as the object of natural selection but also an active subject that can change their own selective pressure through eco-evolutionary feedbacks.

A note on structural holes theory and niche overlap [PDF]
Social Networks, 2003 Diffuse competition due to niche overlap between actors without (direct) ties with each other, constrains their structural autonomy. This is not dealt with in Burt’s mathematical model of his well-known structural holes theory. We fix his model by introducing a network measure of niche overlap.

Disentangling niche theory and beta diversity change [PDF]
The American Naturalist, 2021 Abstract Beta diversity describes the differences in species composition among communities. Changes in beta diversity over time are thought to be due to selection based on species’ niche characteristics. For example, theory predicts that selection that favours habitat specialists will increase beta diversity.

Interference Competition and Niche Theory [PDF]
Proceedings of the National Academy of Sciences, 1974 A linear model of interspecific competition with separate parameters for exploitation and interference is deduced. Interference is assumed to have a cost and an effect. The interfering species realizes a “profit” if some resources, which the species interfered against would have utilized, are made available as a result of the interference. Interference

Operationalizing niche construction theory with stone tools. [PDF]
, 2023 One of the greatest difficulties with evolutionary approaches in the study of stone tools (lithics) has been finding a mechanism for tying culture and biology in a way that preserves human agency and operates at scales that are visible in the ...

Towards the Integration of Niche and Network Theories [PDF]
Trends in Ecology & Evolution, 2018 The quest for understanding how species interactions modulate diversity has progressed by theoretical and empirical advances following niche and network theories. Yet, niche studies have been limited to describe coexistence within tropic levels despite incorporating information about multi-trophic interactions.
