Virus satellites drive viral evolution and ecology [PDF]

open access: yes, 2015
Virus satellites are widespread subcellular entities, present both in eukaryotic and in prokaryotic cells. Their modus vivendi involves parasitism of the life cycle of their inducing helper viruses, which assures their transmission to a new host. However,

One Health – an Ecological and Evolutionary Framework for tackling Neglected Zoonotic Diseases [PDF]

open access: yes, 2015
Understanding the complex population biology and transmission ecology of multihost parasites has been declared as one of the major challenges of biomedical sciences for the 21st century and the Neglected Zoonotic Diseases (NZDs) are perhaps the most ...

Longitudinal Analysis of Antimicrobial Resistance among Enterococcus Species Isolated from Australian Beef Cattle Faeces at Feedlot Entry and Exit

open access: yesAnimals, 2022
Enterococcus faecium are commensal bacteria inhabiting the gastrointestinal tract of animals and humans and an important cause of drug-resistant nosocomial infections.

Evidence for an ecological cost of enhanced herbicide metabolism in Lolium rigidum [PDF]

open access: yes, 2009
1. In some cases, evaluation of resource competitive interactions between herbicide resistant vs. susceptible weed ecotypes provides evidence for the expression of fitness costs associated with evolved herbicide-resistant gene traits. Such fitness costs

Natural history of Arabidopsis thaliana and oomycete symbioses [PDF]

open access: yes, 2008
Molecular ecology of plant–microbe interactions has immediate significance for filling a gap in knowledge between the laboratory discipline of molecular biology and the largely theoretical discipline of evolutionary ecology.
