[CBNPMP-Thèmes] Mauvaises herbesRésumé : Dans le sud-est de la France, où persistent des exploitations agricoles extensives incluant l'élevage ovin de parcours, les fourrages issus de champs de céréales moissonnés (chaumes et adventices) permettent le bouclage de la saison de pâturage. En revanche, peu de données sont disponibles sur la valeur nutritive de ces fourrages (teneurs en minéraux). Dans une exploitation agricole représentative des pratiques menées dans la majorité de celles du territoire du Parc naturel régional du Luberon (Vaucluse), les teneurs en minéraux de fourrages échantillonnés dans trois parcelles écologiquement contrastées (prairie humide, friche post-culturale, pelouse sèche) et une parcelle moissonnée ont été dosées. Nos résultats montrent que le fourrage échantillonné dans la parcelle moissonnée présente une biomasse sèche significativement inférieure à celle des trois autres parcelles entre juillet et octobre 1999. Cependant la valeur nutritive du fourrage de chaumes avec les adventices apparaît très intéressante en période estivale car les teneurs en cellulose et cendres insolubles sont significativement inférieures. Au contraire, pour les matières azotées totales et les éléments calcium, magnésium et potassium, ses teneurs sont significativement supérieures.

Titre : The contribution of spatial mass effects to plant diversity in arable fields Type de document : Imprimé Auteurs : Helen Metcalfe ; Kirsty L. Hassall ; Sébastien Boinot ; Jonathan Storkey Année de publication : 2019 Article en page(s) : 1560-1574 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Messicole Résumé : 1 In arable fields, plant species richness consistently increases at field edges. This potentially makes the field edge an important habitat for the conservation of the ruderal arable flora (or ‘weeds’) and the invertebrates and birds it supports. Increased diversity and abundance of weeds in crop edges could be owing to either a reduction in agricultural inputs towards the field edge and/or spatial mass effects associated with dispersal from the surrounding landscape. 2 We contend that the diversity of weed species in an arable field is a combination of resident species, that can persist under the intense selection pressure of regular cultivation and agrochemical inputs (typically more ruderal species), and transient species that rely on regular dispersal from neighbouring habitats (characterised by a more ‘competitive’ ecological strategy). 3 We analysed a large dataset of conventionally managed arable fields in the UK to study the effect of the immediate landscape on in-field plant diversity and abundance and to quantify the contribution of spatial mass effects to plant diversity in arable fields in the context of the ecological strategy of the resulting community. 4 We demonstrated that the decline in diversity with distance into an arable field is highly dependent on the immediate landscape, indicating the important role of spatial mass effects in explaining the increased species richness at field edges in conventionally managed fields. 5 We observed an increase in the proportion of typical arable weeds away from the field edge towards the centre. This increase was dependent on the immediate landscape and was associated with a higher proportion of more competitive species, with a lower fidelity to arable habitats, at the field edge. 6 Synthesis and applications. Conserving the ruderal arable plant community, and the invertebrates and birds that use it as a resource, in conventionally managed arable fields typically relies on the targeted reduction of fertilisers and herbicides in so-called ‘conservation headlands’. The success of these options will depend on the neighbouring habitat and boundary. They should be placed along margins where the potential for ingress of competitive species, that may become dominant in the absence of herbicides, is limited. This will enhance ecosystem services delivered by the ruderal flora and reduce the risk of competitive species occurring in the crop.

Titre : The ecology and conservation of rare arable weed species and communities Type de document : Électronique Auteurs : Philip Wilson (1958-) ; Nigel Boatman, Directeur de thèse ; Peter John Edwards (1948-), Directeur de thèse Editeur : University of Southampton Année de publication : 1990 Importance : 385 p. Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Messicole Résumé : Since 1940, considerable changes have occurred in both arable farming practices and arable weed floras in Britain. The aim of this project was to investigate the ecology of a range of annual weed species in relation to farming practices, in order to suggest some reasons for the decline in frequency of some species, and to propose some methods by which populations may be conserved. A survey of the sites at which eight uncommon species are still found, demonstrated the strong association of the weed communities and the presence of individual species, with the cropping history and soil characteristics of fields. Climatic factors and the long-term histories of sites were also found to be important. Another survey demonstrated the tendency for the seed-banks of most weed species to be greatest at the extreme edge of fields. Four herbicides were tested against ten weed species, and the effects of levels of nitrogen application on 18 weed species were investigated. It is believed that herbicide use and the high levels of nitrogen applied to modern crop varieties have favoured their growth at the expense of weeds. The type of crop sown and the date of sowing also had a great influence on the development of the weed flora. Some species rely on a post-harvest stubble in order to set seed. Changes in arable weed communities and the status of rare species is thought to be a result of changes in the farming practices described above in addition to others not investigated. Management guidelines based on the experimental investigations are proposed. Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=149187 Wilson, P. 1990.

Titre : The effects of arable field margin management on the abundance and species richness of Araneae (spiders) Type de document : Imprimé Auteurs : M. Baines ; Clive Hambler (1960-) ; Paul J. Johnson ; David Whyte Macdonald (1951-) ; Helen Smith Année de publication : 1998 Article en page(s) : 74-86 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Messicole Résumé : The effects of ten different management regimes on the abundance and species richness of Araneae on pre-existing and newly expanded zones of field margins surrounding arable fields are compared in a large-scale experiment conducted between 1987 and 1991. Most of the management regimes involved varying the Liming and frequency with which the field margins were cut. There was no evidence of consistent temporal trends in the abundance and species richness of Araneae on either the existing or expanded zones of the field margins during the first four years of the experiment. However, lowest numbers were recorded before expansion of the margins in 1987, and highest numbers in the final sample, in 1991. Araneae remained less abundant, and less species rich, on the newly expanded than on the existing zones of the field margins four years after they were set-aside'. Culling reduced both abundance and species richness. Regimes which included culling in mid-summer had a greater impact which persisted for longer than did those involving cutting in spring and autumn. Removal of cut material was associated with lower species richness than leaving it in situ. Sowing the margins with a wild flower seed mixture was associated with increased abundance and species richness of Araneae. Annual spraying with a broad-spectrum, non-persistent herbicide reduced the abundance of Araneae but the effect was not detectable until several months after the application of the spray. Both the species richness and abundance of Araneae were positively correlated with a measure of vegetation height made on the field margins in September, on both the pre-existing and newly expanded zones of the margins. The extent to which management practices which benefit Araneae are compatible with both the management requirements for various other taxa. and the overriding constraint of effective pernicious weed control on field margins, is discussed.
