“…The mean population sizes of helminth parasites in the rabbits were similar to those already reported from Scotland and England (BOAG, 1972;1985) but the T. retortaeformis numbers found in the mountain hares were greater than any previously recorded (IRVIN, 1970;SOVERI & VALTONEN, 1983). Sub-clinical parasitism by T. retortaeformis may possibly be one of the contributing factors responsible for the fluctuations in hare numbers (ANGERBJORN & HJERNQUIST, 1984) since the over-all mean population was in excess of 3600 nematodes per hare which is higher than the numbers of similar related species which have been shown to have a detrimental effect on the growth of lambs (SPEDDING & BROWN, 1957). BARTH & BRULL (1975) were able to demonstrate the harmful effects of parasites when they fed apples treated with an anthelmintic to wild brown hares and managed to control the parasites and get significant increases in body-weight.…”

“…However, other factors, such as predator abundance, size and condition of female hares, food abundance and weather/climate may also be responsible for the variation in hare population dynamics, irrespective of the phase of the hare cycle (Flux 1970, Angerbjörn & Hjernquist 1984, Hewson 1985, Angerbjörn 1986, Danell & Hörnfeldt 1987, Marcström et al 1989. For instance, Hewson (1985) and Angerbjörn & Hjernquist (1984) found that population declines were due to low survival rate of adult hares caused by harsh weather and, consequently, a shortage of food. Low food availability caused by thick snow cover also resulted in big loss of embryos and, thus, low productivity among mountain hares (Flux 1970).…”
