The benefits of organic farming to biodiversity in agricultural landscapes continue to be hotly debated, emphasizing the importance of precisely quantifying the effect of organic vs. conventional farming. We conducted an updated hierarchical meta-analysis of studies that compared biodiversity under organic and conventional farming methods, measured as species richness. We calculated effect sizes for 184 observations garnered from 94 studies, and for each study, we obtained three standardized measures reflecting land-use intensity. We investigated the stability of effect sizes through time, publication bias due to the ‘file drawer’ problem, and consider whether the current literature is representative of global organic farming patterns. On average, organic farming increased species richness by about 30%. This result has been robust over the last 30 years of published studies and shows no sign of diminishing. Organic farming had a greater effect on biodiversity as the percentage of the landscape consisting of arable fields increased, that is, it is higher in intensively farmed regions. The average effect size and the response to agricultural intensification depend on taxonomic group, functional group and crop type. There is some evidence for publication bias in the literature; however, our results are robust to its impact. Current studies are heavily biased towards northern and western Europe and North America, while other regions with large areas of organic farming remain poorly investigated. Synthesis and applications. Our analysis affirms that organic farming has large positive effects on biodiversity compared with conventional farming, but that the effect size varies with the organism group and crop studied, and is greater in landscapes with higher land-use intensity. Decisions about where to site organic farms to maximize biodiversity will, however, depend on the costs as well as the potential benefits. Current studies have been heavily biased towards agricultural systems in the developed world. We recommend that future studies pay greater attention to other regions, in particular, areas with tropical, subtropical and Mediterranean climates, in which very few studies have been conducted.

“…For instance, the regional pool of species contributing to a given ESS might be affected by landscape management and the corresponding quantity and quality of habitat structures (Flohre et al 2011). This is especially relevant for organisms which switch between an aquatic and a terrestrial phase during their life cycle (e.g.…”

In a cross-disciplinary project (LEGATO) combining inter-and transdisciplinary methods, we quantify the dependency of rice-dominated socio-ecological systems on ecosystem functions (ESF) and the ecosystem services (ESS) the integrated system provides. In the collaboration of a large team including geo-and bioscientists, economists, political and cultural scientists, the mutual influences of the biological, climate and soil conditions of the agricultural area and its surrounding natural landscape have been analysed. One focus was on sociocultural and economic backgrounds, another on local as well as regional land use intensity and biodiversity, and the potential impacts of future climate and land use change. LEGATO analysed characteristic elements of three service strands defined by the Millennium Ecosystem Assessment (MA): (a) provisioning services: nutrient cycling and crop production; (b) regulating services: biocontrol and pollination; and (c) cultural services: cultural identity and aesthetics. However, in line with much of the current ESS literature, what the MA called supporting services is treated as ESF within LEGATO. As a core output, LEGATO developed generally applicable principles of ecological engineering (EE), suitable for application in the context of future climate and land use change. EE is an emerging discipline, concerned with the design, monitoring and construction of ecosystems and aims at developing strategies to optimise ecosystem services through exploiting natural regulation mechanisms instead of suppressing them. Along these lines LEGATO also aims to create the knowledge base for decision-making for sustainable land management and livelihoods, including the provision of the corresponding governance and management strategies, technologies and system solutions.

Collembola communities were studied in different agricultural habitats including intensively managed plant cultures, shelterbelts and grassy embankments in the area of the LAJTA Project. A total of 62 species were collected during the eleven-year study period (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). Three species, namely Axenyllodes bayeri, Metaphorura denisi and Pseudosinella aelleni have proven to be new to the Hungarian fauna. Collembola species richness, abundance and diversity were the highest in shelterbelts, which shows their ecological role in agricultural environments. Grassy embankments are further important ecotone habitats that play significant role in soil fauna diversity and abundance. Intensively managed monocultures (maize, summer rape and winter wheat) were characterized by Collembola communities with low species richness and abundance.KULCSZAVAK: ugróvillás, agrárélőhely, szegély ökotonok KEY WORDS: Collembola, agrohabitat, edge ecotones BEVEZETÉSAz ugróvillások úgynevezett elsődlegesen szárnyatlan (Apterygota), belső szájszervű (Entognatha) rovarok. Régebben "ősrovaroknak", a mai "modern" rovarok ősének gondolták ezt a csoportot, de mostani tudásunk szerint inkább egy különálló fejlődési csoportot, a "Parainsecta"-t reprezentálják a hajnalrovarokkal (Protura) és a lábaspotrohúakkal (Diplura) közösen. Vizsgálatunkat a LAJTA Projecten belül nem az indokolja, hogy közvetlen kapcsolatban állnak az ottani szárnyas apróvad (pl. fogoly, fácán) állományaival, hanem az, hogy az ugróvillások a szárazföldi ökoszisztémák leggyakoribb rovarai (hivatkozás). Átlagos szabályként mondhatjuk, hogy zavartalan, természet közeli élőhelyeken ~1000 példányuk él minden liter földben (hivatkozás). A mezofauna tagjaként közvetett jelentőségük a fogolypopulációra éppen óriási egyedszámukból következik: nevezetesen a táplálkozási piramis alján, gyakorlatilag minden, a fogoly számára is fontos ragadozó ízeltlábúnak (farkaspókok, futóbogarak, százlábúak) zsákmányállatát képezik. Így biztosan állíthatjuk, hogy ahol gazdag ugróvillás-közösség él, ott gazdag macrofauna és bő táplálékkínálat van a rovarevő fajok számára is. Mindezen túl az ugróvillások tevékenysége a holt szerves anyag fogyasztása, lebontása, valamint a talajflóra megfelelő baktérium-gomba arányának kialakításában jelentős.
