Modelling the Role of Temperature-Induced Environmental Noise on Phytoplankton Niche Dynamics

open access: yesFrontiers in Marine Science, 2022
Variability in physical and chemical processes in the marine ecosystem significantly influences the niche ecology of primary producers. However, studies are limited to understand the role of variability in environmental conditions on the niche dynamics ...

Development of environmental niche models for use in underwater vehicle navigation [PDF]

open access: yesIET Cyber-systems and Robotics, 2020
This paper presents a review of Environmental Niche Modeling and a methodology for isolating the environmental niche of an aquatic species, given that prior information is available for characterising the physical tolerances for that species. To test and

Evaluating the risk for Usutu virus circulation in Europe: comparison of environmental niche models and epidemiological models [PDF]

open access: yesInternational Journal of Health Geographics, 2018
Background Usutu virus (USUV) is a mosquito-borne flavivirus, reported in many countries of Africa and Europe, with an increasing spatial distribution and host range.

Abundance and the Environmental Niche: Environmental Suitability Estimated from Niche Models Predicts the Upper Limit of Local Abundance [PDF]

open access: yesThe American Naturalist, 2009
Ecologists seek to understand patterns of distribution and abundance of species. Studies of distribution often use occurrence data to build models of the environmental niche of a species. Environmental suitability (ES) derived from such models may be used to predict the potential distributions of species.

Niche shifts and environmental non-equilibrium undermine the usefulness of ecological niche models for invasion risk assessments [PDF]

open access: yesScientific Reports, 2020
AbstractNiche shifts and environmental non-equilibrium in invading alien species undermine niche-based predictions of alien species’ potential distributions and, consequently, their usefulness for invasion risk assessments. Here, we compared the realized climatic niches of four alien amphibian species (Hylarana erythraea, Rhinella marina ...

Environmental niche modelling as tool for pest risk assessment

open access: yesPLANT PROTECTION NEWS, 2021
The article reviews the concept and technology of pest risk assessment for the spread of quarantine species based on ecological and geographical analysis and ecological niche modeling. Using a quarantine species Ipomoea hederacea (L.) Jacq. as an example, we calculated the ecological requirements of the species. The main ecological factors limiting the

Environmental Niche and Demographic Modeling of American Chestnut near its Southwestern Range Limit [PDF]

open access: yesThe American Midland Naturalist, 2021
AbstractThe inadvertent introduction and rapid spread of chestnut blight (caused byCryphonectria parasitica(Murr.) Barr) in the early 20th century resulted in the demise of American chestnut (Castanea dentata(Marsh.) Borkh.; Fagaceae) as a major component of forest canopies and had negative impacts on eastern forest communities.

Environmental Niche Adaptation Revealed Through Fine Scale Phenological Niche Modeling [PDF]

open access: yesJournal of Biogeography, 2019
ABSTRACTAimPhenology, the temporal response of a population to its climate, is a crucial behavioral trait shared across life on earth. How species adapt their phenologies to climate change is poorly understood but critical in understanding how species will respond to future change.

Are we overestimating the niche? Removing marginal localities helps ecological niche models detect environmental barriers [PDF]

open access: yesEcology and Evolution, 2016
AbstractCorrelative ecological niche models (ENMs) estimate species niches using occurrence records and environmental data. These tools are valuable to the field of biogeography, where they are commonly used to infer potential connectivity among populations. However, a recent study showed that when locally relevant environmental data are not available,
