Carnivores are often particularly sensitive to landscape fragmentation. Ecological corridors may help to connect local populations, ensuring gene flow and retaining viable meta-populations. We aimed to establish habitat suitability models for two large carnivores in Poland, the grey wolf Canis lupus Linnaeus, 1758 and the Eurasian lynx Lynx lynx Linnaeus, 1758, based on ecological niche factor analysis...

Dla borsuków Meles meles miarą jakości siedlisk leśnych może być biomasa dżdżownic oraz możliwość kopania nor. Najbardziej zasobne w dżdżownice są łąki i pastwiska, a spośród lasów grądy i olsy, natomiast najbardziej ubogie w te bezkręgowce są bory sosnowe i świerkowe. Dodatkowo, w górach biomasa dżdżownic zmniejsza się wraz ze wzrostem wysokości nad poziomem morza. Dominacja monokultur iglastych...
Using data from the National Wolf Census, carried out in Poland in 2000–2001, and GIS techniques we analysed habitat selection by wolvesCanis lupus Linnaeus, 1758 in uplands and mountains of southern Poland. We compared ten habitat variables and two parameters related to wolf abundance in 52 circular plots (154 km2 each) with recorded wolves and 97 randomly selected plots with no signs of wolf presence...
