The coloration in gibbons varies by individual, making it difficult for researchers and conservationists to distinguish between species.<\/span><\/p>\n<p><span style=\"color: #000000\">But as Sarah Zielinski reported in yesterday\u2019s <em>Surprising Science<\/em> post, <a href=\"http:\/\/www.biomedcentral.com\/1471-2148\/11\/36\/abstract\">scientists<\/a> from the German Primate Center in Goettingen examined the songs of seven species of crested gibbons and found that each species had its own distinct dialect.<\/span><\/p>\n<p><span style=\"color: #000000\">\u201cThe researchers found that the songs of the two northern species,<em> <\/em><em>N. nasutus<\/em><em> <\/em>and<em> <\/em><em>N. concolor<\/em>, were significantly different from those of the four southern species, and the songs of the four southern species were all subtly different from one another. And the more closely related two species or populations songs were, the more alike was their mitochondrial DNA.\u201d<\/span><\/p>\n<p><span style=\"color: #000000\">The findings, said the researchers, could help to monitor gibbon populations through song, as opposed to visual, recognition. In addition, continued Welsh,<em> <\/em>\u201c[t]he gradation of song similarity between the northern and southern populations supports the idea that the genus began in the north and migrated toward the south.\u201d<\/span><\/p>\n<p><a href=\"http:\/\/blogs.smithsonianmag.com\/science\/2011\/02\/crested-gibbons-sing-in-different-dialects\/\">Read more<\/a><em> at \u201cCrested Gibbons Sing in Different Dialects.\u201d<\/em><\/p>\n<p>Photo Credit: <a href=\"http:\/\/www.flickr.com\/photos\/stuutje\/4497907314\/\">Tim Strater<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Birds are not the only animals that communicate by singing\u2014gibbons, apes more closely resembling monkeys in size, sing to strengthen social relationships, announce their territory and find a mate.
