Journal ArticleDOI
Distribution and abundance of small insects and arachnids in relation to structural heterogeneity of grazed, indigenous grasslands
TL;DR: The species composition and spatial distribution of small insects and arachnids and Araneae, Opiliones, and Pseudoscorpiones were investigated in three indigenous, upland grasslands identified as the National Vegetation Classification Festuca–Agrostis–Galium typical subcommunity.
Journal ArticleDOI
Field margins: can they enhance natural enemy population densities and general arthropod diversity on farmland?
Peter Dennis,Gary L.A. Fry +1 more
TL;DR: The enhancement of natural enemies and general arthropod conservation are discussed as components of overall biological diversity at the farm scale.
Journal ArticleDOI
The effects of livestock grazing on foliar arthropods associated with bird diet in upland grasslands of Scotland
Peter Dennis,John Skartveit,David I. McCracken,Robin J. Pakeman,Katy Beaton,A. Kunaver,Darren M. Evans +6 more
TL;DR: Dennis, P., Skartveit, J., Mccracken, D.I., Pakeman, R.J., Beaton, K., Kunaver, A.M. and Evans, D as mentioned in this paper studied the effects of livestock grazing on foliar arthropods associated with bird diet in upland grasslands of Scotland.
Journal ArticleDOI
Structural features of field boundaries which influence the overwintering densities of beneficial arthropod predators
TL;DR: Winter survival was lowest for beetles enclosed on bare earth and highest for those enclosed on tussocks of Dactylis glomerata, while the contrast in structural complexity of the experimental treatments caused a 44%, 43% and 36% variation in the final densities of beetles during three successive winters.
Journal ArticleDOI
Impacts of climate on prey abundance account for fluctuations in a population of a northern wader at the southern edge of its range
TL;DR: This work examines the likely importance of variation in prey abundance in driving the demographics of a European golden plover population at its southern range margin, and modelled the phenology of both plover breeding and cranefly emergence in relation to temperature.
