The tenet that ecological opportunity drives adaptive diversification has been central to theories of speciation since Darwin, yet no widely accepted definition or mechanistic framework for the concept currently exists. We propose a definition for ecological opportunity that provides an explicit mechanism for its action. In our formulation, ecological opportunity refers to environmental conditi...

Abstract We here develop a concept of an individualized niche in analogy to Hutchison’s population-level the ecological niche. consider (ecological) as range environmental conditions under which particular individual has expected lifetime reproductive success ≥ 1. Our primarily function, it refers match phenotype its contemporary environment (niche fit) while we discuss evolutionary fitness eva...

Organisms can receive not only a genetic inheritance from their ancestors but also an ecological inheritance, involving modifications their ancestors made to the environment through niche construction. Ecological inheritances may persist as a legacy, potentially generating selection pressures that favor sociality. Yet, most proposed cases of sociality being impacted by an ecological inheritance...

Boivin et al.’s (1) article profoundly deepens scientific understanding of anthropogenic global ecological change from Pleistocene to present by offering robust new evidence of early human transformation of the biosphere that should influence discussions on Anthropocene formalization (2, 3). As ecologists and evolutionary theorists, we applaud this work. However, we are also concerned that this...

Estimating actual and potential areas of distribution of species via ecological niche modeling has become a very active field of research, yet important conceptual issues in this field remain confused. We argue that conceptual clarity is enhanced by adopting restricted definitions of "niche" that enable operational definitions of basic concepts like fundamental, potential, and realized niches a...

1. The concept of the ecological niche relates a set of environmental variables to the fitness of species, while habitat suitability models (HSMs) relate environmental variables to the likelihood of occurrence of the species. In spite of this relationship, the concepts are weakly linked in the literature, and there is a strong need for better integration. 2. We selectively reviewed the literatu...

The purpose of ecological niche modelling is to obtain a probabilistic species distribution based on species localization and environmental data. The problem is highly complex from the architectural viewpoint because its requirements include different distributed, interoperable and integration issues. Monolithic solutions were proposed and implemented but they were not able to achieve all requi...

■ Abstract Niche conservatism is the tendency of species to retain ancestral ecological characteristics. In the recent literature, a debate has emerged as to whether niches are conserved. We suggest that simply testing whether niches are conserved is not by itself particularly helpful or interesting and that a more useful focus is on the patterns that niche conservatism may (or may not) create....

Niche construction theory (NCT) explicitly recognizes environmental modication by organisms ("niche construction") and their legacy overtime ("ecological inheritance") to be evolutionary processes in their own right. Here we illustrate how niche construction theory provides usedl conceptual tools and theoretical insights for integrating ecosystem ecology and evolutionary theory. We begin by bri...
