Since the first sporadic occurrences of grey wolves (Canis lupus) west of the Polish border in 1996, wolves have shown a rapid population recovery in Germany. Wolves are known to avoid people and wolf attacks on humans are very rare worldwide. Howeve

In the southern North Sea, harbour porpoise occurrence increased in recent years after a phase of low abundances during earlier decades. Only very few studies on porpoise presence in the southern German North Sea exist so far. As anthropogenic activi

The Mongolian share of the Palaearctic steppe biome hosts some of most intact grassland regions, these are traversed by high peaks creating diverse and rich habitats. We sampled 100 randomly located vegetation plots in a 2 × 2 km² mountain summit r
