9、the walls are a key part of the problem,the study suggests.These salt crystals go into the cave walls,changing sizes as temperatures rise and fall.This process causes the rock to slowly break down.Salt crystals may become larger when exposed to repeated changes between wet conditions and periods of
10、drought.These kinds of changes are expected to become more obvious as the climate continues to warm.In particular,the researchers say,climate change may cause more intense El Nino(厄尔尼诺)events in the future.These events can strengthen the kinds of conditions that help salt crystals form Scientists ar

17、t are not their own.The study,published in Zoo Biology,suggests that captive-bred wolfcubs(幼兽)could be placed with wild wolf families,boosting the wild population.The gray wolf was once the worlds most widely distributed mammal,but it became extinct as a result of widespread habitat destruction and
18、the deliberate killing of wolves suspectedof preying on livestock.Fear and hatred of the wolf have since become culturally rooted,fuelled by myths,fables and stories.In Scandinavia,the gray wolf is endangered,the remaining population found by just five animals.As a result,European wolves are severel

23、-living families,which already have cubs of a similar age,not only will they have a good chance of survival,but they could help dramatically increase the diversity of the wild population,say the researchers.Just like the wild wolves they would join,these foster cubs would need protection from huntin
