Predicting coexistence of plants subject to a tolerance-competition trade-off

open access: yes, 2013
Ecological trade-offs between species are often invoked to explain species coexistence in ecological communities. However, few mathematical models have been proposed for which coexistence conditions can be characterized explicitly in terms of a trade-off.

Microbial metabolism: optimal control of uptake versus synthesis [PDF]

open access: yes, 2014
Microbes require several complex organic molecules for growth. A species may obtain a required factor by taking up molecules released by other species or by synthesizing the molecule.

Towards the Development of an Evolutionarily Valid Domain-Specific Risk-Taking Scale

open access: yesEvolutionary Psychology, 2007
From an evolutionary perspective, human risk-taking behaviors should be viewed in relation to evolutionarily recurrent survival and reproductive problems.

Grand challenges for the spatial information community

open access: yesJournal of Spatial Information Science, 2020
The spatial information (SI) community has an opportunity to address major societal and scientific problems including public health, climate change, air pollution, transportation, and others. Beyond the significant contributions made by the SI community,

Molecular evolution between chemistry and biology [PDF]

open access: yesEuropean Biophysics Journal, 2018
Biological evolution is reduced to three fundamental processes in the spirit of a minimal model: (i) Competition caused by differential fitness, (ii) cooperation of competitors in the sense of symbiosis, and (iii) variation introduced by mutation understood as error-prone reproduction. The three combinations of two fundamental processes each, ([Formula:

The IQ‐compete assay for measuring mitochondrial protein import efficiencies in living yeast cells

open access: yesFEBS Letters, EarlyView.
The efficiency of mitochondrial protein import depends on the properties of the newly synthesized precursor proteins. The Import and de‐Quenching Competition (IQ‐compete) assay is a novel method to monitor the import efficiency of different proteins by fluorescence in living yeast cells.

Effects of temporal variability on rare plant persistence in annual [PDF]

open access: yes, 2004
Traditional conservation biology regards environmental fluctuations as detrimental to persistence, reducing long-term average growth rates and increasing the probability of extinction.

Kinetic modelling of competition and depletion of shared miRNAs by competing endogenous RNAs

open access: yes, 2018
Non-conding RNAs play a key role in the post-transcriptional regulation of mRNA translation and turnover in eukaryotes. miRNAs, in particular, interact with their target RNAs through protein-mediated, sequence-specific binding, giving rise to extended ...
