Experiments on sprainting activity of otters ( Lutra lutra ) in the Bieszczady Mountains, southeastern Poland / Observations des épreintes de la loutre ( Lutra lutra ) sur les montagnes du Bieszczady au sud-est de la Pologne
Abstract Consecutive surveys of otter spraints of both banks along a 28-km stretch of the River San showed an average of 4.18 deposited spraints/km per day during a 3-week pre-experimental period. The variation in spraint density on particular 1-km-long sections of the river was high and varied from...
