Cognitive niches: An ecological model of strategy selection.

Psychological Review, 2011
How do people select among different strategies to accomplish a given task? Across disciplines, the strategy selection problem represents a major challenge. We propose a quantitative model that predicts how selection emerges through the interplay among strategies, cognitive capacities, and the environment.

Dynamical model for sympatric speciation in an ecological niche.

Theoretical biology forum, 2019
The speciation phenomenon is the process used by the evolution to allow populations to become distinct species. The speciation is the primary cause of the complexity of the ecological network. Sympatric speciation concerns the rise of a new species from a surviving ancestral species while both continue to inhabit the same ecological niche or ...

Programming Ecological Niche Modeling Workflows in the Cloud

2013 27th International Conference on Advanced Information Networking and Applications Workshops, 2013
In the last decades biology scientists have relied on their own resources and tools to run the experiments and store the results of the analysis. However, the explosion of big data and the growing availability of computational methods find an obstacle in the lack of computational and storage resources.

Modeling Ecological Niches

2011
This chapter explains how environmental data can be used to create models that characterize species’ ecological niches in environmental space. It introduces a model, which is a function constructed by means of data analysis for the purpose of approximating the true relationship (that is, the niche) in the form of the function f linking the environment ...

Representing Ecological Niches in a Conceptual Model

2004
The niche concept has been recognised as a fundamental notion in biological and business systems, amongst others. Existing data models do not have adequate primitives that faithfully represent ecological niches for geographical information systems.

Ecological Niche Modeling of Acanthamoeba in Türkiye

EcoHealth
Acanthamoeba, is an opportunistic pathogenic organism with a global distribution and the potential to cause severe human infections. This study primarily aimed to identify the environmental factors influencing the distribution of Acanthamoeba by analyzing various bioclimatic and topographic variables, and to predict their potential current and future ...

Ditch the niche – is the niche a useful concept in ecology or species distribution modelling?

Journal of Biogeography, 2012
AbstractIn this first of three papers we examine the use of niche concepts in ecology and especially in species distribution modelling (SDM). This paper deliberately focuses on the lack of clarity found in the term ‘niche’. Because its meanings are so diverse, the term niche tends to create confusion and requires constant qualification.

The Niche-Center Relationship in Ecological Niche Modeling

The niche-center relationship posits that organisms’ fitness is highest at the center of their fundamental ecological niche, an assumption often implicit in ecological niche modeling. Nevertheless, empirical support for the niche-center relationship at the species level is often inconsistent, potentially due to confounding factors such as biotic ...

EXPERIMENTAL VERIFICATION OF ECOLOGICAL NICHE MODELING IN A HETEROGENEOUS ENVIRONMENT

Ecology, 2006
The current range of ecological habitats occupied by a species reflects a combination of the ecological tolerance of the species, dispersal limitation, and competition. Whether the current distribution of a species accurately reflects its niche has important consequences for the role of ecological niche modeling in predicting changes in species ranges ...

Spatial modelling of Bacillus anthracis ecological niche in Zimbabwe

Preventive Veterinary Medicine, 2013
Anthrax continues to cause significant mortalities in livestock, wildlife and humans worldwide. In Zimbabwe, anthrax outbreaks have been reported almost annually over the past four decades. In this study we tested whether anthrax outbreak data and a set of environmental variables can be used to predict the ecological niche for Bacillus anthracis using ...
