AB  - To gain some insight into the structure of the hoverfly community in fields of oilseed rape (Brassica napus L.), we conducted field experiments over three years (2011-2013) at two localities in the province of Vojvodina, northern Serbia. We recorded a total of 20 hoverfly species. Three species-Episyrphus balteatus (De Geer, 1776), Eristalis tenax (Linnaeus, 1758) and Eupeodes corollae (Fabricius, 1794)-were the most abundant in both localities and in each year. In order to determine the effect of climatic and non-climatic parameters on abundance and diversity of hoverflies, two separate PCA analyses were carried out. Multiple linear regressions were used to examine the relationships between abundance and extracted PC axes, while ordinal multinomial regressions were conducted to determine the relationships between species diversity and extracted PC axes. We did not detect statistically significant correlations between climatic and non-climatic parameters and overall hoverfly abundance. PC axes exhibited slight correlation with species diversity. The first PC axis clearly showed that overall species diversity increases with increasing temperature, relative humidity and diversity of crops surrounding the surveyed plots, whereas PC2 related species composition with monthly average rainfall and the season and year of observation. Synecological analysis of our data indicated that only a few species are major contributors to hoverfly communities on the oilseed rape crops we investigated. However, the importance of less abundant hoverfly species should not be underestimated, as sometimes these species play an important role in pollination in a specific part of the day or season, and this should be considered when creating agricultural policies and regulations, especially when it is known that abundances of hoverflies and pollinators in general are positively correlated with floral abundance and abundance flowering plant species.

AB  - There is insufficient available information on structural changes within wood-pastures including their relationship to abiotic influences such as livestock grazing, flooding and available soil nutrients. In this paper, we address the links between important environmental variables and different stages of the wood-pasture cycle, with the aim of understanding fluctuations in this relationship and processes that follow changes in wood-pasture condition. We used satellite and aerial image interpretation to identify structural vegetation shifts over 44 years under significantly declining livestock numbers. We used ground truthing of 24 plots to assess the current field scenario and employed canonical correspondence analysis (CCA) to evaluate the relationship between plant communities and environmental influences. Three dominant structural vegetation types grassland, transitional vegetation with thorny shrubs and woody encroachment were surveyed and the following set of variables was chosen: grazing intensity, inundation frequency, elevation, soil total nitrogen, soil available phosphorus, soil potassium, soil magnesium, soil calcium, soil pH and soil carbon to nitrogen ratio. Interpretation of satellite images revealed dominance of wood-pasture in the past, which alternated structurally between more open and more closed physiognomies. CCA with ground truthing data and forward selection revealed grazing intensity as the predominant ecological driver modifying vegetation structure, as well as transitioning vegetation patterns between open herbaceous and closed woody cover. Each structural vegetation type demonstrated a collective distribution pattern and a close relationship to certain abiotic drivers, indicating strong interactions between soil parameters, grazing pressure and vegetation composition.
