How do plant community ecologists consider the complementarity of observational, experimental and theoretical approaches ?

Alexandre Buttler, Pierre Rémi Mariotte, François Gillet, Thomas Spiegelberger, Aurélie Thébault

Background and aims -- A panoply of methods are used by ecologists for studies at the plant community level. While early studies were mainly descriptive, more manipulative experiments are now being undertaken because they provide a more functional approach ...

Mechanisms of vegetation uprooting by flow in alluvial non-cohesive sediment

Paolo Perona, Katharina Maria Edmaier

The establishment of riparian pioneer vegetation is of crucial importance within river restoration projects. After germination or vegetative reproduction on river bars juvenile plants are often exposed to mortality by uprooting caused by floods. At later s ...

Integration of Coplanar Barium-Strontium Titanate Tunable Capacitors on Micro-Machined Silicon

Nava Setter, Alexander Tagantsev

The fabrication and characterization of coplanar Barium-Strontium Titanate capacitors on Silicon are described. Micromachining was used to reduce parasitic effects stemming from the substrate, thus enhancing the performance of the device. ...

How Does Plant Diversity Affect Soil Aggregate Stability and Erosion Processes in Disturbed Alpine Ecosystems?

Plant species diversity is hypothesized to be among the most relevant factors for enhancing soil stability in disturbed sites at high elevation. Because a more diverse plant community may comprise a high number of plant species of different growth forms, p ...

ITER CODAC interface for the visible and infra-red wide angle viewing cameras

Jonathan Bryan Lister

The amount of data generated by the infra-red and visible cameras at ITER is expected to be considerably larger than most diagnostics. ITER will have 12 infra-red cameras plus 12 visible cameras in four different equatorial port plugs. Each of the ports wi ...

POLLEN CLUMPING AND WIND DISPERSAL IN AN INVASIVE ANGIOSPERM

Marc Parlange, Charles Vivant Ignacio Meneveau, Michael David Martin

Pollen dispersal is a fundamental aspect of plant reproductive biology that maintains connectivity between spatially separated populations. Pollen clumping, a characteristic feature of insect-pollinated plants, is generally assumed to be a detriment to win ...

No Evidence for the Induction of Brown Algal Chemical Defense by the Phytohormones Jasmonic Acid and Methyl Jasmonate

Induced chemical defense reactions are widespread in marine brown algae. Despite the evidence that the biosynthesis of defense metabolites can be up-regulated upon herbivory, we do not know how this regulation of biosynthetic pathways to secondary metaboli ...

Conserved oviposition preferences in alpine leaf beetle populations despite host shifts and isolation

Anthony Christopher Davison

Choosing the plant on which to lay their eggs is the last act of care that most female herbivorous insects bestow upon their offspring. These decisions play a pivotal role in insect–plant interactions, placing host preference under strong selection and ...

Medicinal properties of organometallic compounds

Paul Joseph Dyson, Claire Samantha Allardyce

Although organometallic compds. are ubiquitous in nature, synthetic organometallic compds. are generally considered to be toxic or non-compatible with biol. systems. Despite this perception the medicinal properties of organometallic compds., in particular ...

Biotic interactions of marine algae

UMR 1931, CNRS and Laboratoires Goemar, Station Biologique, 29680 Roscoff, France. Marine algae encompass lineages that diverged about one billion years ago. Recent results suggest that they feature natural immunity traits that are conserved, as well as ot ...
