As top predators, they can change the populations of prey species, which in turn affects the rest of the food chain. Conversely, dependence on a particular prey species, whose populations may fluctuate over time, can impact the killer whales' survival. By collecting observational data and skin\/blubber samples, scientists will be able to better understand and protect these killer whales.","html":"<iframe src='https:\/\/www.globalgiving.org\/dy\/v2\/oembed\/?format=html&url=https%3A%2F%2Fwww.globalgiving.org%2Fprojects%2Fkiller-whales-and-their-prey-in-iceland%2F' style='width:920px;height:613px;border:0;'><\/iframe>","type":"rich","title":"Killer Whales and Their Prey in Iceland on GlobalGiving","thumbnail_url":"https:\/\/www.globalgiving.org\/pfil\/25043\/pict_large.jpg","version":"1.0","height":"613"}
