Synthesizing a novel genetic sequential logic circuit: a push‐on push‐off switch

open access: yesMolecular Systems Biology, 2010
Design and synthesis of basic functional circuits are the fundamental tasks of synthetic biologists. Before it is possible to engineer higher‐order genetic networks that can perform complex functions, a toolkit of basic devices must be developed.

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 ...

Casanovas are liars : behavioral syndromes, sperm competition risk, and the evolution of deceptive male mating behavior in live-bearing fishes [version 2; referees: 2 approved, 1 approved with reservations] [PDF]

open access: yes, 2013
Male reproductive biology can by characterized through competition over mates as well as mate choice. Multiple mating and male mate choice copying, especially in internally fertilizing species, set the stage for increased sperm competition, i.e., sperm ...

The Field of Cell Competition Comes of Age: Semantics and Technological Synergy

open access: yesFrontiers in Cell and Developmental Biology, 2022
Stem cells experience many selective pressures which shape their cellular populations, potentially pushing them to skew towards dominance of a few break-through clones. An evolutionarily conserved answer to curb these aberrant selective pressures is cell

Principles of parametric estimation in modeling language competition [PDF]

open access: yes, 2013
It is generally difficult to define reasonable parameters and interpret their values in mathematical models of social phenomena. Rather than directly fitting abstract parameters against empirical data, we should define some concrete parameters to denote ...

Biology, distribution and geographic variation of loliginid squids (Mollusca: Cephalopoda) off southwestern Atlantic

open access: yesZoologia (Curitiba), 2018
The biology and ecology of southwestern Atlantic loliginid squids have been intensively researched in the last few decades, mostly off the Brazilian southern coast.

The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]

open access: yes, 2012
Bacterial genomes commonly contain ‘addiction’ gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.

A systematic review of context bias in invasion biology.

open access: yesPLoS ONE, 2017
The language that scientists use to frame biological invasions may reveal inherent bias-including how data are interpreted. A frequent critique of invasion biology is the use of value-laden language that may indicate context bias.

Competition-based screening helps to secure the evolutionary stability of a defensive microbiome

open access: yesBMC Biology, 2021
Background The cuticular microbiomes of Acromyrmex leaf-cutting ants pose a conundrum in microbiome biology because they are freely colonisable, and yet the prevalence of the vertically transmitted bacteria Pseudonocardia, which contributes to the ...

Kin selection in interactions between gametes: Gamete competition, gamete limitation, and sex allocation

open access: yesFrontiers in Ecology and Evolution, 2023
Kin selection on one hand, and gamete interactions in post-ejaculatory sexual selection on the other are two major research themes that have risen to prominence over the past half century and have simultaneously developed into central fields of research ...
