Aim To assess the effects of inorganic fertilizer application to winter cereals on breeding-season usage by farmland birds. Methods We measured bird usage of winter-sown cereal fields across a gradient of inorganic fertilizer inputs and tested for influences of management intensity and availability of semi-natural habitat on species richness and abundance of farmland birds. Results Avian species richness and bird abundance were unrelated to fertilizer inputs, and declined at higher levels of total vegetation cover. Sky Lark abundance increased, while Yellow Wagtail counts declined with the extent of semi-natural habitat. Sky Lark abundance increased with vegetation cover and peaked at an intermediate level of weed species richness. Yellow Wagtail counts peaked at intermediate levels of fertilizer inputs. Conclusions Compared with much of western Europe, cereal production in central Hungary is characterized by modest fertilizer inputs and large areas of semi-natural habitat. There was little evidence that increased applications of fertilizer are likely to have negative impacts on farmland birds, although increased application might reduce habitat suitability for Yellow Wagtails. Loss of semi-natural habitat is likely to have negative impacts on Sky Larks."],["dc.description.sponsorship","EASY [QLK5-CT-2002-01495]; Faunagenesis project [NKFP 3B023-04]"],["dc.identifier.doi","10.1080/00063657.2011.582853"],["dc.identifier.isi","000295732100011"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/24125"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Taylor & Francis Ltd"],["dc.relation.issn","0006-3657"],["dc.title","Effects of fertilizer application on summer usage of cereal fields by farmland birds in central Hungary"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In Hungary, special agri-environment schemes in Environmentally Sensitive Areas require the establishment of sown set-aside fields especially for endangered bird species. We tested if these set-aside fields are beneficial for plants and insects of agricultural landscapes. We compared the herbaceous flora, grasshopper (Orthoptera), bee (Apidae) and butterfly (Rhopalocera) fauna of five field types (1, 2 and 3 year-old set-aside, winter cereal fields and semi-natural grasslands). Species richness, abundance and species composition of insects were tested against field type and plant species richness. The wheat fields were the poorest habitats for all taxa. The species richness and abundance of the studied insects were usually higher in set-aside than in cereal fields with no significant difference between set-aside of different age. We found the highest number of orthopteran species and butterfly individuals in semi-natural grasslands. At community level, field type and plant species richness had a significant effect on orthopteran assemblages. Butterfly assemblages were significantly affected by field type. Bee assemblages were not significantly related to the above variables. We can conclude that set-aside fields provide important habitat patches for plants and insects, in some cases with similar value to semi-natural grasslands. Our results emphasise the importance of set-aside within the Hungarian agri-environment scheme. Establishment of set-aside management in other Central European countries will likely to be of a similar value as the Hungarian set-aside fields. (C) 2011 Elsevier B.V.

Location: Central Hungary. Methods: Vascular plants were sampled in 18 winter cereal fields along an intensification gradient according to nitrogen fertilization, in the first cereal rows (edge) and in the interior part of the fields. Weed species were divided into groups according to their residence time in Central Europe (native species, archaeophytes, neophytes) and nitrogen preference (low to medium, LMNP, and high, HNP species). The percentage of semi-natural habitats was calculated in the 500 m radius circle. Effects of fertilizer use, transect position and semi-natural habitats were estimated by general linear mixed models. Results: We recorded 149 weed species. Fertilizer had a negative impact on the species richness of archaeophytes and LMNP species, and on the cover of native weeds. There was greater species richness and weed cover at the edge of the fields than in the centre. A higher percentage of seminatural habitats around the arable fields resulted in greater total species richness, especially of archaeophytes and LMNP species. We found an interaction between the percentage of semi-natural habitats and transect position for species richness of archaeophytes and LMNP species. Conclusions: Reduced use of fertilizers and a high percentage of semi-natural habitats would support native and archaeophyte weed diversity even in winter cereal fields, while large amounts of fertilizer may promote invasion of neophytes. However, the beneficial effect of the semi-natural habitats and greater species pool on the arable flora may prevail only in the crop edges."],["dc.identifier.doi","10.1111/j.1654-109X.2010.01098.x"],["dc.identifier.isi","000286207100005"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/23962"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1402-2001"],["dc.title","Interaction of local and landscape features in the conservation of Hungarian arable weed diversity"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Although bees are the most important pollinators, they are endangered by intensive agricultural practices. The present study investigated the effects of farmland management and environmental factors at local and landscape scales on bees in Central Hungary. Bees were sampled in winter cereal fields that varied in the amount of applied fertilizer and insecticide use. Measurements included total, small and large bee species richness and abundance; stability of total species richness and abundance (coefficient of variation, CV); the nitrogen content of fertilizers; the number of insecticide applications; within-field location; species richness and abundance of insect-pollinated plants; and the percentage of semi-natural areas in a 500-m radius circle around the fields under study. Increasing the amount of fertilizer decreased total and small bee abundance and increased the CV of total bee abundance. Insecticide use had a significant negative effect on total and small bee species richness and on large bee abundance. The percentage of semi-natural habitats in a 500-m radius did not influence bee species richness and abundance. The results obtained confirms that the intensification of farmland management poses a threat to bee diversity, and thus may reduce pollination services. Recently-introduced agri-environment schemes are one potential approach for managing agricultural land use: reduced amounts of fertilizer and a cessation of insecticide application might lead to high bee species richness and abundance and ensure the pollination of wild plants and flowering crops."],["dc.identifier.doi","10.1111/j.1461-9563.2010.00498.x"],["dc.identifier.isi","000286054100006"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/23957"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1461-9555"],["dc.title","Local and landscape effects on bee communities of Hungarian winter cereal fields"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
