Just like some people , elephants seem to prefer a ample pallet of foods , research out this week advise . Studying decades - old poop , researcher establish that elephant be given to have diverse diets that can differ significantly from others in the same residential area . These diets are further influenced by the meter of year and the elephants ’ specific consideration .
Past inquiry has been able-bodied to show the broad strokes of an elephant ’s industrial plant - base diet . But conservation scientists at Brown University and elsewhere wanted to truly understand the food preferences of these gentle giants and how these preference might be shaped by their environment and residential area . Elephants are societal animate being , living and scrounge for food in magnanimous group .
“ When I talk to non - ecologist , they are stunned to determine that we have never really had a clear mental picture of what all of these charismatic enceinte mammals actually eat in nature , ” said study source Tyler Kartzinel , an assistant professor of environmental studies and of ecology , organic evolution , and organismic biology at Brown , in astatementfrom the university . “ The reasonableness is that these animals are unmanageable and dangerous to observe from up - close , they move foresighted distances , they feed at night and in thick bush and a raft of the plants they feed on are quite little . ”

To get a good aspect at the elephant dieting , the team relied on a relatively new pattern of transmitted psychoanalysis called DNA “ metabarcoding . ” This technique allowed investigator to describe the traces of many unlike living thing within a single sample distribution — in this case , quarter roll up about 20 years earlier from elephant in two separate communities in Kenya , Africa . The team scotch - referenced what they found against a deoxyribonucleic acid database of plants in the area . They also combined their results with other forms of analytic thinking , including GPS tracking , to help influence the fluctuation in diet between somebody in these group .
All told , they identified at least 367 genetically clear-cut type ( or taxa ) of plants that had been recently eaten by the elephants , and up to 137 unique plants within a single shite sample . On an individual level , their diets could alter widely , even among elephants that eat on together that same day .
The findings , publishedWednesday in the journal Royal Society Open Science , seem to help serve some important questions about elephant and their company , the authors say . While know in groups would offer many benefits for these animals , it could also potentially threaten their survival by drive them to vie for the same intellectual nourishment . The researchers found some environmental factor that might limit their choices — diets were typically less diverse during the dry season , for instance . But in oecumenical , it appears that elephant have sidestepped this trouble by take over widely wide-ranging dieting .
This enquiry should n’t just help oneself scientist understand elephants well , but also better their betting odds of survival in the time to come , the authors say . Conservation elbow grease , for case , might need to check that that elephants have accession to a diverse range of plants in the expanse . And by doing so , we might also reduce the risk of elephants inadvertently harming humans by going after their crop or other beginning of intellectual nourishment .
“ Wildlife populations need access to diverse dietetic resources to prosper , ” Kartzinel said . “ Each elephant needs variety , a little bit of spice — not literally in their food , but in their dietetical habits . ”
