Evolution of Resource Competition between Mutually Dependent Digital Organisms [PDF]

, 2004
We study the emergence and dynamics of competing strains of digital organisms in a world with two depletable resources. Consumption of one resource produces the other resource as a by-product, and vice versa.

Ecological niche modeling of the genus Papio

American Journal of Physical Anthropology, 2018
AbstractObjectiveEcological niche modeling (ENM) has been used to assess how abiotic variables influence species distributions and diversity. Baboons are broadly distributed throughout Africa, yet the degree of climatic specialization is largely unexplored for individual taxa. Also, the influence of climate on baboon phylogenetic divergence is unknown.

Predicting Distribution of Aedes Aegypti and Culex Pipiens Complex, Potential Vectors of Rift Valley Fever Virus in Relation to Disease Epidemics in East Africa. [PDF]

, 2013
The East African region has experienced several Rift Valley fever (RVF) outbreaks since the 1930s. The objective of this study was to identify distributions of potential disease vectors in relation to disease epidemics.

Regional Variation Exaggerates Ecological Divergence in Niche Models [PDF]

Systematic Biology, 2010
Traditionally, the goal of systematics has been to produce classifications that are both strongly supported and biologically meaningful. In recent years several authors have advocated complementing phylogenetic analyses with measures of another form of evolutionary change, ecological divergence. These analyses frequently rely on ecological niche models

Eltonian Niche Modelling: Applying Joint Hierarchical Niche Models to Ecological Networks

Ecology Letters
ABSTRACT There is currently a dichotomy in the modelling of Grinnellian and Eltonian niches. Despite similar underlying data, Grinnellian niches are modelled with species‐distribution models (SDMs), whereas Eltonian niches are modelled with ecological‐network analysis, mainly because the sparsity of species‐interaction data prevents ...

Ecologic Niche Modeling of Blastomyces dermatitidis in Wisconsin

PLoS ONE, 2008
Blastomycosis is a potentially fatal mycosis that is acquired by inhaling infectious spores of Blastomyces dermatitidis present in the environment. The ecology of this pathogen is poorly understood, in part because it has been extremely difficult to identify the niche(s) it occupies based on culture isolation of the organism from environmental samples ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Eco-epidemiological mechanisms of avian influenza and Newcastle virus co-infection: Spatial convergence and compatibility

Poultry Science
Understanding the mechanisms of viral co-infection in natural host populations is crucial for predicting pathogen dynamics and cross-species transmission risks.

Comparative analysis of remotely-sensed data products via ecological niche modeling of avian influenza case occurrences in Middle Eastern poultry

International Journal of Health Geographics, 2011
Background Ecological niche modeling integrates known sites of occurrence of species or phenomena with data on environmental variation across landscapes to infer environmental spaces potentially inhabited (i.e., the ecological niche) to generate ...

mMWeb--an online platform for employing multiple ecological niche modeling algorithms. [PDF]

PLoS ONE, 2012
BACKGROUND: Predicting the ecological niche and potential habitat distribution of a given organism is one of the central domains of ecological and biogeographical research. A wide variety of modeling techniques have been developed for this purpose.
