Population dynamics of epigeic Collembola in arable fields: the importance of hedgerow proximity and crop type
journal contribution
posted on 2023-06-08, 19:03 authored by T Alvarez, G K Frampton, Dave GoulsonDave GoulsonDuring spring 1996, the temporal and spatial dynamics of epigeic Collembola, in southern UK, were studied in fields planted with spring barley and vining peas. Composition of the fauna varied according to crop type and position within the field. Proximity of a hedgerow had a major impact upon population dynamics, with more species and a greater over all abundance near field edges. It was the major factor governing the abundance of Isotomurus palustris and Bourletiella hortensis, whereas crop type was most important in determining numbers of Jeannenotia stachi, Sminthurus viridis, Sminthurinus elegans and Lepidocyrus spp. Temporal variation in species abundance was also clear: abundances of J. stachi, B. hortensis, I. palustris and Lepidocyrtus spp. decreased through the sampling period while those of S. viridis and Isotoma viridis increased. Overall, the management practices associated with the two crops were an important determinant of collembolan abundance but not of species composition.
