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.

Ecological niche models improve home range estimations

Journal of Zoology, 2020
AbstractHome ranges in animals can be estimated by different methods like minimum convex polygons, characteristic hulls or kernels while correlative ecological niche models (ENMs) are commonly employed for forecasting species' ranges. However, ENMs can also model the distribution of individuals if environmental very high spatial resolution data are ...

Modelling ecological niches with support vector machines

Journal of Applied Ecology, 2006
SummaryThe ecological niche is a fundamental biological concept. Modelling species’ niches is central to numerous ecological applications, including predicting species invasions, identifying reservoirs for disease, nature reserve design and forecasting the effects of anthropogenic and natural climate change on species’ ranges.A computational analogue ...

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.

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 ...

Simulation-Based Approaches for Ecological Niche Modelling

2016
Over recent years, many modelling approaches have been used to map and monitor both present and potential distribution of species in the context of ecological niche-based conservation, especially in the face of global environmental change. Using different statistical techniques in a built-in geographic information system (GIS), the development of ...

Using ecological niche modelling to evaluate niche stability in deep time

Journal of Biogeography, 2011
AbstractAim  To investigate relative niche stability in species responses to various types of environmental pressure (biotic and abiotic) on geological time‐scales using the fossil record.Location  The case study focuses on Late Ordovician articulate brachiopods of the Cincinnati Arch in eastern North America.Methods  Species niches were modelled for a

Niche divergence between putative taxa: ecological niche models in taxonomic researches

2017
For over a century, species delimitation was a critical task for biologists, concerning both species concept and operational methods necessary for the individuation of taxa boundaries. According to the recent approach of integrative taxonomy, species have to be considered as hypotheses that should be tested with different methods.
