Active lithoautotrophic and methane-oxidizing microbial community in an anoxic, sub-zero, and hypersaline High Arctic spring
Lost Hammer Spring, located in the High Arctic of Nunavut, Canada, is one of the coldest and saltiest terrestrial springs discovered to date. It perennially discharges anoxic (
2022Evolutionary history expands the range of signaling interactions in hybrid multikinase networks
Anne-Florence Raphaëlle Bitbol, Mohamed Barakat
Two-component systems (TCSs) are ubiquitous signaling pathways, typically comprising a sensory histidine kinase (HK) and a response regulator, which communicate via intermolecular kinase-to-receiver domain phosphotransfer. Hybrid HKs constitute non-canonic ...
NATURE RESEARCH2021Burial-induced oxygen-isotope re-equilibration of fossil foraminifera explains ocean paleotemperature paradoxes
Oxygen-isotope compositions of fossilised planktonic and benthic foraminifera tests are used as proxies for surface-and deep-ocean paleotemperatures, providing a continuous benthic record for the past 115 Ma. However, visually imperceptible processes can a ...
Springer Nature2017Allelopathic Activity of the Iron Chelator Anachelin-A Molecular Hybrid with a Dual Mode of Action
One of the compounds suggested to be responsible for the cyanobacterial dominance over competing green algae is identified. Evidence is provided on the molecular, chemical level that the iron chelator anachelin from the cyanobacterium Anabaena cylindrica p ...
Wiley-V C H Verlag Gmbh2016Mitochondrial DNA Analyses Indicate High Diversity, Expansive Population Growth and High Genetic Connectivity of Vent Copepods (Dirivultidae) across Different Oceans
Communities in spatially fragmented deep-sea hydrothermal vents rich in polymetallic sulfides could soon face major disturbance events due to deep-sea mineral mining, such that unraveling patterns of gene flow between hydrothermal vent populations will be ...
Public Library of Science2016Attenuated sensing of SHH by Ptch1 underlies evolution of bovine limbs
Denis Duboule, Guillaume Andrey, Dagmar Iber, Jing Liu
The large spectrum of limb morphologies reflects the wide evolutionary diversification of the basic pentadactyl pattern in tetrapods. In even-toed ungulates (artiodactyls, including cattle), limbs are adapted for running as a consequence of progressive red ...
Nature Publishing Group2014Diversity in the Archean Biosphere: New Insights from NanoSIMS
Anders Meibom, François Robert
The origin of organic microstructures in the similar to 3 Ga Farrel Quartzite is controversial due to their relatively poor state of preservation, the Archean age of the cherts in which they occur, and the unusual spindle-like morphology of some of the for ...
2010NanoSIMS: Insights to biogenicity and syngeneity of Archaean carbonaceous structures
Anders Meibom, François Robert
NanoSIMS is a relatively new technology that is being applied to ancient carbonaceous structures to gain insight into their biogenicity and syngeneity. NanoSIMS studies of well preserved organic microfossils from the Neoproterozoic (similar to 0.8Ga) Bitte ...
2009Novelty of Behaviour as a Basis for the Neuro-evolution of Operant Reward Learning
An agent that deviates from a usual or previous course of action can be said to display novel or varying behaviour. Novelty of behaviour can be seen as the result of real or apparent randomness in decision making, which prevents an agent from repeating exa ...
ACM2009The influence of competition from herbaceous vegetation and shade on simulated browsing tolerance of coniferous and deciduous saplings
Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux
The ability of saplings to tolerate browsing (i.e. the ability to persist with reduced biomass and to compensate for biomass loss) is influenced by the level of stress and their growth strategies. Ultimately, insight into species-specific responses of sapl ...
