Despite being a protected species, the lynx do not colonize all forests in Poland. New research shows that most forests do not meet key requirements, such as the presence of undergrowth or type of terrain, that give these predators the opportunity to hunt.
Non-English-language literature is the primary source of knowledge for nature and biodiversity policy makers in 37 countries surveyed by an international team of scientists. Publishing houses should take care of translating articles into many languages, the authors of the study believe.
Biologists from the University of Lodz are attempting to determine whether there will soon be a massive invasion of the hybrid crustacean Dikerogammarus villosus in Polish rivers. It threatens fauna because it feeds on fish eggs and displaces local species that live in European waters.
According to popular belief, any bear that smells honey cannot resist and will break into the apiary. Scientists have found that this is not true. They used DNA samples taken at the 'crime' sites to show that two thirds of the bears in the north-eastern Carpathians do not break into hives, despite the fact that many hives are still not properly secured.
Scientists have checked how lynx fare in the landscape of Europe, which is, among other things, heavily transformed by humans and fragmented. It turns out that a combination of the habitat availability and human impact may determine the survival of the species. This is of great importance for their protection, emphasise the study authors including researchers from Poland.
