Long term changes in aquaculture influence migration, regional abundance, and distribution of an avian species.

open access: yesPLoS ONE, 2023
Agricultural development has been causing changes to the environment and the abundance and distribution of avian species. Agriculture is dynamic with changes in products occurring at large scales over relatively short time periods.

Modeling large scale species abundance with latent spatial processes [PDF]

open access: yes, 2009
Modeling species abundance patterns using local environmental features is an important, current problem in ecology. The Cape Floristic Region (CFR) in South Africa is a global hot spot of diversity and endemism, and provides a rich class of species ...

The influence of ecological factors on mosquito abundance and occurrence in Galápagos [PDF]

open access: yesJournal of Vector Ecology, 2018
We sampled mosquitoes across 18 sites established at different elevations and stretching from the north to the south of Isla Santa Cruz, Galápagos. Two commonly occurring species, Ae. taeniorhynchus and Cx. quinquefasciatus, were collected along with environmental variables characteristic of the trapping sites to assess their influence on mosquito ...

Linearity and Scaling of a Statistical Model for the Species Abundance Distribution

open access: yes, 2001
We derive a linear recursion relation for the species abundance distribution in a statistical model of ecology and demonstrate the existence of a scaling ...

Rainfall but not selective logging affect changes in abundance of tropical forest butterfly in Sabah, Borneo [PDF]

open access: yes, 2003
We investigated the effects of rainfall on the distribution and abundance of the satyrine butterfly Ragadia makuta in selectively logged and unlogged forest on Borneo. In 1997-98, there was a severe El Nino-Southern Oscillation (ENSO) drought, and annual

Sponge distribution and the presence of photosymbionts in Moorea, French Polynesia [PDF]

open access: yesPeerJ, 2016
Photosymbionts play an important role in the ecology and evolution of diverse host species within the marine environment. Although sponge-photosymbiont interactions have been well described from geographically disparate sites worldwide, our understanding

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

open access: yes, 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.
