Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...

Frequent Versus Single Active Bouts Differentially Affect Movement Behavior and Energy Balance in Adults With Overweight/Obesity

open access: yesObesity, EarlyView.
ABSTRACT Objective This study aimed to investigate the effects of breaking up sedentary behavior (SB) on daily movement behavior and energy balance in adults with overweight/obesity. Methods Thirty participants (16F/14M; 34.2 ± 7.3 years; 29.5 ± 3.2 kg/m2) were randomized to either BREAK (multiple 5‐min brisk walking bouts) or a duration‐matched ...

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

open access: yesOikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Informing the potential of mature temperate forests as natural climate solutions: Changed fine root biomass and morphology under elevated CO2

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The land carbon sink absorbs approximately 25% of anthropogenic CO2 emissions, with forests accounting for most. Managing forests as Natural Climate Solutions is therefore a societal imperative, requiring models of where and how long carbon resides within these ecosystems. We investigated the effects of elevated CO2 on fine roots, the primary source of

Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

open access: yesPest Management Science, EarlyView.
This article reports the first characterization of Cry2Ab2 resistance in Crocidosema sp. Resistance appears to be autosomal and incompletely recessive, with a major‐gene contribution and potential involvement of additional genetic factors, and did not confer cross‐resistance to Cry1Ac or Cry1A.105. Abstract BACKGROUND The soybean bud borer, Crocidosema

Inheritance and fitness costs of field‐evolved resistance to Gpp34/Tpp35Ab1 corn by western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)

open access: yesPest Management Science, EarlyView.
Field‐evolved resistance to Gpp34/Tpp35Ab1 corn in two western corn rootworm strains was inherited in a non‐recessive manner and was associated with fitness costs. Abstract BACKGROUND The western corn rootworm, Diabrotica virgifera virgifera LeConte, is among the most serious pests of corn in the United States, and an invasive pest in parts of Europe ...

Why rotation and mixture fail: treatment history and the declining acaricide efficacy in Varroa destructor

open access: yesPest Management Science, EarlyView.
The effect of IRM strategies (rotation, mixture), one additional year under acaricide treatment (Years treated (+1 year)), and one year without acaricide treatment (Years off treatment (+1 year) on mite mortality relative to an approximately 17% baseline.

IRM

open access: yes, 2013
L’IRM est devenue une technique puissante dans le domaine de l’imagerie médicale ainsi qu’un outil de soins et de recherche d’où la construction d’un IRM à 11 Tesla au centre de neuro spin de CEA à SARCLAY. En effet cet appareil est devenu vital à la médecine moderne du fait qu’il est le seul moyen de détecter et de diagnostiquer certaines pathologies.
