Old sleeping Sicilian beauty: seed germination in the palaeoendemic Petagnaea gussonei (Spreng.) Rauschert (Saniculoideae, Apiaceae).

2015

Petagnaea gussonei (Apiaceae) is a perennial herbaceous species endemic to northeast Sicily (Nebrodi Mountains). It is considered a remnant of the Sicilian Tertiary flora, and is endangered according to the Red List. There is no information in the literature about the germinability of its seeds, even though seed production is know to occur. The aim of this study was to obtain data to better understand seed germination of this species and its biological implications. Thus, several approaches were employed: vitality analyses, gibberellic acid supply, germination and soil microbial flora analyses via end-point and qPCR. The results suggest that seed germination occurs after ca. 1.5 years at a …

Pigs and Cattle in Gaul: The Role of Gallic Societies in the Evolution of Husbandry Practices

2017

International audience; In diesem Artikel wird eine vergleichende Untersuchung der Morphologie von Schweinen und Rinder vorgelegt sowie eine Analyse stabiler Isotopen, die die Führung des Schweinebestands in Levroux Les Arènes (Indre, Frankreich) betrifft, um die Veränderungen in den Tierhaltungspraktiken zwischen der Eisenzeit und der Römerzeit in der gallischen Gesellschaft auszuwerten. Unsere Ergebnisse zeigen, dass neue Produktionsstrukturen und Vertriebssysteme wahrscheinlich vor dem 2. Jahrhundert v. Chr. eingeführt wurden, und dass bestimmte Größen/Gewichte in der spezialisierten Erzeugung von Schweinefleisch ausgesucht wurden. Die Statur der Schweine und Rinder nimmt zunehmend vom s…

Defoliation effects on Plantago lanceolata resource allocation and soil decomposers in relation to AM symbiosis and fertilization

2009

Plants can mediate interactions between aboveground herbivores and belowground decomposers as both groups depend on plant-provided organic carbon. Most vascular plants also form symbiosis with arbuscular mycorrhizal fungi (AMF), which compete for plant carbon too. Our aim was to reveal how defoliation (trimming of plant leaves twice to 6 cm above the soil surface) and mycorrhizal infection (inoculation of the fungus Glomus claroideum BEG31), in nutrient poor and fertilized conditions, affect plant growth and resource allocation. We also tested how these effects can influence the abundance of microbial-feeding animals and nitrogen availability in the soil. We established a 12-wk microcosm st…

Sleep problems reported by parents affect 20% to 30% of infants. Few studies focused on the longitudinal association between infant feeding practices and sleep, especially in France. Analyses were based on 8,696 infants from the French national birth cohort ELFE. Collection of feeding practices from birth to 10 months allowed for the identification of trajectories of use of baby cereals and thickened formula by group‐based trajectory modelling and calculation of duration of any breastfeeding (BF) and age at complementary feeding introduction (CFI) excluding baby cereals. Total sleep duration (TSD), night waking (NW) and sleep onset difficulties (SOD) were reported at age 1. Associations bet…

Maternal feeding practices during the first year and their impact on infants' acceptance of complementary food.

2013

Funding: Regional Council of Burgundy + Regional Council of IFR92 + Regional Council of PRNH-INRA-INSERM + Regional Council of the "ANR The French National Research Agency" under the Programme National de Recherche en Alimentation et nutrition humaine (ANR-06-PNRA-028 ) + Regional Council of Bledina, Nestle, Symrise, Cedus and Valrhona; International audience; The introduction of weaning foods is a major transition in the development of infants' eating behavior. Previous studies showed that greater variety at the beginning of the weaning period can later influence an infant's acceptance of new foods. The aim of the present study was to describe maternal feeding practices in the first year (…

Toward a better understanding of in-field weed regulation by carabid beetles, and their functional characteristics, in European arable landscapes

2019

For future arable agriculture, there is a need for more sustainable methods to manage weeds that are less reliant on herbicides and maintain food production. Control of weeds by natural enemies is an agro-ecological alternative to reduce the use of herbicides. While strong evidence points to carabid beetles exerting a regulatory effect on certain weed species, it is difficult to predict whether a particular assemblage of carabid species or functional groups will drive the function of weed seed predation in field conditions. There are also uncertainties about which key local and landscape-scale factors affect the function of weed seed predation, and the functional characteristics of carabid …

Goose, Duck and Garganey

2019

Duck, goose and garganey are waterfowls consumed in a lower proportion than chicken. These species are of great economic importance in Asia, Europe and USA. Among the three species, duck is the main bird produced for the meat system while goose is commercially produced by at lower proportion than duck. Differently, garganey is considered as game meat, which has been poorly studied in last decades. The productive system of duck and goose share similarities with which other such as physical structure, animal management, feeding strategies, management of environmental conditions, transport, and slaughter. However, these variables and related aspects of farming and meat processing can be manage…

Spatial and temporal stability of weed populations over five years

2000

Abstract The size, location, and variation in time of weed patches within an arable field were analyzed with the ultimate goal of simplifying weed mapping. Annual and perennial weeds were sampled yearly from 1993 to 1997 at 410 permanent grid points in a 1.3-ha no-till field sown to row crops each year. Geostatistical techniques were used to examine the data as follows: (1) spatial structure within years; (2) relationships of spatial structure to literature-derived population parameters, such as seed production and seed longevity; and (3) stability of weed patches across years. Within years, densities were more variable across crop rows and patches were elongated along rows. Aggregation of …

The impact of weather on COVID-19 pandemic.

2021

AbstractRising temperature levels during spring and summer are often argued to enable lifting of strict containment measures even in the absence of herd immunity. Despite broad scholarly interest in the relationship between weather and coronavirus spread, previous studies come to very mixed results. To contribute to this puzzle, the paper examines the impact of weather on the COVID-19 pandemic using a unique granular dataset of over 1.2 million daily observations covering over 3700 counties in nine countries for all seasons of 2020. Our results show that temperature and wind speed have a robust negative effect on virus spread after controlling for a range of potential confounding factors. T…
