“…Alignier et al Ecological Indicators 85 (2018) 832-840 stakeholders who need to assess the impact of agriculture on biodiversity (Delbaere, 2003;Bockstaller et al, 2011). But few of them are based upon direct measurements of organisms (see Clergué et al, 2005 for an overview) and enable users to analyze the causal relationships between vegetation patterns and management data (Pywell et al, 2011;Ricou et al, 2014). With Ecobordure, we succeed in developing a simple, efficient and reliable indicator allowing users to describe vegetation patterns of field margins according to seven types, homogeneous or mixed, corresponding to the seven sectors of the triangle.…”

A B S T R A C TField margins are key landscape elements contributing to maintain biodiversity in agricultural landscapes. Yet, their ecological value is often poorly assessed and restricted to landscape descriptors, e.g. density or structure of hedgerows. We introduce Ecobordure, a flora-based indicator designed to describe vegetation patterns of field margins and infer on drivers leading to these patterns, i.e. structure and management practices of field margins. Ecobordure first targets agricultural teachers and advisers, who want to learn and help students and farmers to learn about patterns and drivers of field margin vegetation, for promoting management practices favorable to this biodiversity. Here, we present the stages of the Ecobordure design and output validation. The first stage consisted of elucidating the relationship between vegetation composition and structural and management characteristics of field margins. Canonical Correspondence Analyses were performed on empirical datasets derived from field work in bocage regions of Brittany (north-western France). This first stage led to the selection of 31 reference species, quite common, easy-to-recognize and representative of i) the whole community and ii) a wide range of ecological attributes. The 31 reference species were classified in three groups sharing similar life history traits and ecological attributes: "forest-edge", "grassland" and "weed" species. The second stage consisted of the graphical representation of field margins in a triplot diagram, the "Ecobordure triangle", according to the relative percentage of the three species groups. The representation of the Ecobordure triangle was then refined through segmentation in seven sectors to facilitate the reading and interpretation of results. Finally, the output validation of the indicator was performed by testing the consistency between Ecobordure outputs and structural and management characteristics of field margins, using an independent dataset. Our results demonstrate that Ecobordure is a simple, efficient and reliable indicator allowing users to characterize vegetation patterns of field margins and identify potential drivers leading to these patterns. In its original form, Ecobordure can be applied to a broad spectrum of field margins in European bocage regions with temperate oceanic climate, on acidic to neutral soil. However, its use can be extended to other agricultural regions through adaptation of the species list. We conclude by giving some information about Ecobordure use and appropriation by end users. IntroductionBiodiversity in agricultural landscapes is associated with both seminatural elements, e.g. woodland and hedgerows, and productive even intensively-managed elements such as crop and grassland fields (Fahrig et al., 2011). All these elements are interspersed in landscapes and inter-related by structural relationships, ecological processes and agricultural management decisions (Burel and Baudry, 1999). Therefore, segregating areas for conservation cannot be the only way to ma...

“…In coffee farms, habitats with greater flowering tree richness support a greater abundance and diversity of wild bees (Jha and Vandermeer 2010), as do habitats with greater herbaceous plant diversity (Klein, Steffan-Dewenter, and Tscharntke 2003). Other studies show that non-crop vegetation such as herbaceous flowering field margins can support a greater abundance and diversity of bumblebees (Carvell et al 2007;Pywell et al 2011) and other native bees (Batary et al 2010a;Hopwood 2008;Williams et al 2015). Hedgerows attract bee species that are otherwise rare in agricultural settings (Hannon and Sisk 2009) and can increase the abundance and diversity of native bees and syrphid flies , increase the phenotypic diversity of the communities (Ponisio, M'Gonigle, and Kremen 2016), and even possibly increase pollinator persistence and colonization relative to unmanaged field edges.…”

Agroecological research has improved our understanding of the drivers and benefits of biodiversity, thus providing the scientific basis needed to achieve agricultural multifunctionality. We review how agroecology has contributed to our understanding of the effects of local and landscape level drivers on beneficial insects, as well as on the ecosystem services they provide. Several syntheses from agroecosystem research indicate that both populations and biodiversity of pollinator and natural enemies decline with increases in local agricultural intensification and that landscape composition and configuration may mediate these local scale effects. Changes in agricultural management may affect predation and pollination services by altering the resource base for natural enemies and pollinators, by altering their species pool, and by modifying their interactions. The effects of these drivers depend on taxonomical or functional groups and landscape context. Studies that directly measure the cascading effects of landscape drivers on pest control and pollination services and plant level benefits are sparse. We propose five research themes to improve our understanding of the interface of agroecology, conservation, and ecosystem service research.

ABSTRACT:Agriculture ecosystems have provided congenial habitat for various butterfly species. The Papilionidae and Nymphalidae family member's most of their life cycle is depended on natural plant communities amidst agriculture ecosystems. To record few butterflies viz., Papilio polytes, Graphium agamemnon, Ariadne merione and Junonia hierta, agriculture ecosystems were selected randomly and visited frequently by adapting five-hundred-meter length line transects during 2014 to 2016. Study sites were visited during 0800 to 1700 hours and recorded the ovipositing behaviour of gravid female of these butterfly species by following standard methods.Eggs along with the host plant leaves / shoot / twigs were collected in a sterilized Petri dish and brought to the laboratory for further studies. Eggs were maintained under sterilized laboratory conditions till hatching. Newly hatched larvae were fed with their preferred host plants foliage and reared by following standard methods. P. polytes and G. agamemnon and A. merione and J. hierta developmental stages included egg, larva, pupa and adult and these stages have showed significant variation (F=21.35; P>0.01). Further, all the four species had four moults and five instars in their larval stage. However, including larval period, pupal duration was also varied considerably among these species. Further, overall life cycle completed in 43, 32.5 to 40, 21 to 30 and 21 to 29 days by P. polytes, G. Agamemnon, A. merione and J. hierta respectively. Thus, time taken to complete the developmental stages viz., egg, larva, pupa and imago in the life cycle of Papilionidae and Nymphalidae family members exhibited significant variations under laboratory conditions. This kind of observations are essential to know the life cycle duration and in turn help undertake measures to protect these species under man-made habitats like agriculture ecosystems where human interference is maximum.
