How Spatial Locality Can Affect the Evolution of Niche Construction
Niche construction is a process whereby organisms that modify their own or the others’ niches through their ecological activities. It is getting much attention in evolutionary studies but still poorly understood. Our purpose is to clarify the effects of spatial locality of niche construction on the evolution of the niche-constructing trait. Especially, we focus on the evolution of negative nich...
متن کاملRapid evolution of adaptive niche construction in experimental microbial populations.
Many species engage in adaptive niche construction: modification of the local environment that increases the modifying organism's competitive fitness. Adaptive niche construction provides an alternative pathway to higher fitness, shaping the environment rather than conforming to it. Yet, experimental evidence for the evolutionary emergence of adaptive niche construction is lacking, leaving its ...
متن کاملEcological and evolutionary consequences of niche construction for its agent.
Niche construction can generate ecological and evolutionary feedbacks that have been underinvestigated so far. We present an eco-evolutionary model that incorporates the process of niche construction to reveal its effects on the ecology and evolution of the niche-constructing agent. We consider a simple plant-soil nutrient ecosystem in which plants have the ability to increase the input of inor...
متن کاملWhy developmental niche construction is not selective niche construction: and why it matters
In the last decade, niche construction has been heralded as the neglected process in evolution. But niche construction is just one way in which the organism's interaction with and construction of the environment can have potential evolutionary significance. The constructed environment does not just select for, it also produces new variation. Nearly 3 decades ago, and in parallel with Odling-Sme...
متن کاملMetapopulation dynamics and distribution, and environmental heterogeneity induced by niche construction
Niche construction means that all organisms modify their environments, also known as ecosystem engineering. Organism– environmental relations induced by niche construction profoundly influence the dynamics, competition, and diversity of metapopulations. Single-species model shows a positive feedback between metapopulation and environmental resources, which leads to threshold phenomena in dynami...
متن کاملThe Niche Construction Perspective: a Critical Appraisal*
Niche construction refers to the activities of organisms that bring about changes in their environments, many of which are evolutionarily and ecologically consequential. Advocates of niche construction theory (NCT) believe that standard evolutionary theory fails to recognize the full importance of niche construction, and consequently propose a novel view of evolution, in which niche constructio...
