Vegetation quality and habitat selection by European haresLepus europaeus in a pastural landscape

“…They are also smaller, have lower medium--term fat reserves and are less likely to participate in breeding than hares in arable landscapes (Jennings et al 2006). This is not due to diet quality (Jennings et al 2006), and does not appear to be due to the availability of high quality habitats in terms of forage (protein, fat or energy).…”

“…They are also smaller, have lower medium--term fat reserves and are less likely to participate in breeding than hares in arable landscapes (Jennings et al 2006). This is not due to diet quality (Jennings et al 2006), and does not appear to be due to the availability of high quality habitats in terms of forage (protein, fat or energy). Hares in pastural landscapes have smaller home ranges than those in arable landscapes (Smith et al 2004) although they are able to cover relatively large ranges when forage quality is low.…”

“…These differences in body condition are not due to differences in dietary quality as it is similar in hares in the 2 landscapes (Jennings et al 2006). However, hares in pastural landscapes may need to expend more energy to obtain a similar quality diet to those in arable landscape.…”

“…In pastural landscapes numbers of hares are lower than in arable landscapes Parsons 1984, Hutchings andHarris 1996), and hares may be limited by the availability of good quality habitats as they have less kidney fat and are smaller than hares in arable landscapes (Jennings et al 2006). These differences in body condition are not due to differences in dietary quality as it is similar in hares in the 2 landscapes (Jennings et al 2006).…”

A mezei nyúl (Lepus europaeus) állományának változása a Dévaványai Túzokvédelmi Mintaterületen és két kontrollterületen (2008‒2012)

“…Ezt bizonyította a Túzokvédelmi Mintaterületen alkalmazott vetésforgó alkalmazása, itt mértük 2008 októberében a legnagyobb állománysűrűséget, amely elérte a 3,76 db/ha értéket. A rendszeresen legeltetett gyepek esetében a kedvező szántóföldi kultúráknál alacsonyabb egyedsűrűséggel találkozhatunk (SMITH et al, 2005;JENNINGS et al, 2006), amely mind a három mintaterület esetében érzékelhető volt.…”
