For each woodlot the following variables were determined: seasonal changes in the rate of reproduction, population density, fecundity of females in terms of three indices such as the size, validity, and viability of cocoons, also potential and realized productivity of the population, and percentage losses as a result of egg and young mortality. It has been found that birch-aspen woodlots as compared with pine-oak woodlots provide more suitable conditions for survival and reproduction of Enoplognatha ovata populations. Also small forest islands, or these located close to other islands or large forests, are more suitable for reproduction of this spider.}, type={Text}, title={Fecundity of the spider Enoplognatha ovata Cl. in woodlots of the agricultural landscape of north-eastern Poland}, URL={http://rcin.org.pl/Content/83555/PDF/WA058_88188_P2840-T39_Eko-Pol-A-Nr-4.pdf}, volume={39}, number={4}, journal={Ekologia Polska}, publisher={Polish Scientific Publishers}, keywords={spiders, fecundity, woodlots, landscape}, }
