Hydrological changes regulate fish metacommunity structures and β-diversity patterns in the floodplain lake, China

open access: yesEcological Indicators, 2023
The metacommunity structures are continuously dynamic, and understanding the temporal species distribution patterns and biodiversity variations will elucidate the metacommunity theory. To examine whether the idealized metacommunity structuring, diversity

Phenotypic mixing and hiding may contribute to memory in viral quasispecies [PDF]

open access: yes, 2003
Background. In a number of recent experiments with food-and-mouth disease virus, a deleterious mutant, was found to avoid extinction and remain in the population for long periods of time. This observation was called quasispecies memory.

Living Collections of Threatened Plants in Botanic Gardens: When Is Ex Situ Cultivation Less Appropriate than Quasi In Situ Cultivation?

open access: yesJournal of Zoological and Botanical Gardens, 2023
Botanic gardens play an increasingly important role in the conservation of global biodiversity. However, although botanical gardens periodically report the results of introducing certain species of native flora, they rarely attempt to summarize existing ...

An evolutionary model for simple ecosystems

open access: yes, 1999
In this review some simple models of asexual populations evolving on smooth landscapes are studied. The basic model is based on a cellular automaton, which is analyzed here in the spatial mean-field limit.

A criterion based on computational singular perturbation for the construction of reduced mechanism for dimethyl ether oxidation [PDF]

open access: yesJournal of the Serbian Chemical Society, 2013
A criterion based on the computational singular perturbation (CSP) method is proposed in order to determine the number of quasi-steady state (QSS) species.

Seabird meta-Population Viability Model (mPVA) methods

open access: yesMethodsX, 2022
The seabird meta-population viability model (mPVA) uses a generalized approach to project abundance and quasi-extinction risk for 102 seabird species under various conservation scenarios.

Hepatitis C Virus Quasi‐Species Dynamics Predict Progression of Fibrosis after Liver Transplantation [PDF]

open access: yesThe Journal of Infectious Diseases, 2004
The dynamics of hepatitis C virus (HCV) quasi species in the E2 region may correlate with the course of infection after orthotopic liver transplantation (OLT).Thirty-four patients who underwent transplantation for HCV-related cirrhosis were studied.

Modeling viral coevolution: HIV multi-clonal persistence and competition dynamics [PDF]

open access: yes, 2005
The coexistence of different viral strains (quasispecies) within the same host are nowadays observed for a growing number of viruses, most notably HIV, Marburg and Ebola, but the conditions for the formation and survival of new strains have not yet been ...
