The two species are very similar genetically so males of both species will be attracted to females, which is why we are seeing a mix-up in the breeding.. The researchers found larger litter sizes when the mothers were in a good body condition and when spring breakup occurred later in the year, meaning bears had more time on the sea ice in spring to find food.

We are looking at an evolutionary change in the long term where overlaps are increasing and polar bears dont have a lot of options. Humans are doing a lot more than warming the planet, so hybridization is not the only issue that has the potential to decrease biodiversity. Without these colors, the birds would not be aware that these butterflies contain cyanide, and the defense mechanism would be useless. The students were asking many questions after reading.
