Aardvarks ( Orycteropus afer ) are probably the most endearingly doofy - depend animals ever to adorn the African continent . These Seussian snufflers search like someone throw an anteater , a rabbit , a pig , and an armadillo into a smelter . anteater have entered the cognisance of one thousand thousand of child as both the first animate being in any alphabetical listing , and the species ID of the titular character reference of the alive seriesArthur . This all seduce determination ina newfangled paperpublished in the Royal Society journal Biology Letters particularly hard to hear : mood change may kill off magnanimous numbers of anteater , to the point of regional extinction ( or ‘ extirpation ’ ) in many areas .
Currently , anteater seem to be doing fine for themselves . They are found throughout much of sub - Saharan Africa , barring the hot and driest part . However , as clime change get on , the country that aardvarks inhabit in are predicted to gethotter and drier , with longer and more frequent drought . count aardvarks ’ avoidance of toasty , desert part , the coming climatical shift is more than a little menacing for the specie . A squad of South African scientists meditate the physiologic flexibleness of aardvarks received a glimpse into how this scenario could play out by track the organic structure temperature and movement of aardvarks during a viciously hot and dry summer — conditions that closely retroflex Africa ’s predicted next mood .
The researcher implanted sensor record body temperature and forcible body process ( ‘ biologgers ’ ) into six aardvarks inhabiting a semi - arid region of the Kalahari Desert in the wintertime of 2012 . The ant bear were released to go on their merry way for the next eight calendar month , and the biologgers dutifully did what they were designed to do . What then followed was a summer of roughshod extremes . Temperatures make disk senior high school and winds were a third stronger than normal , a combo that turn southerly Africa into a blast furnace and induced stern drought conditions .
At the end of the summertime , it came time to retrieve the biologgers . And how did the aardvarks do ? Well , not great . All but one of the study Orycteropus afer died , and nigh a dozen anteater at the site not a part of the survey also perished . But data from the biologgers revealed that it in all likelihood was n’t heat stroke or dehydration that did them in . In the at rest aardvarks , organic structure temperature stay on relatively constant in the spring and start of the summertime , but declined overall as the summertime progressed , swinging extremely broken at night . The unremarkably nocturnal animal also flipped their schedules , becoming active during the day . This , pair with the fact that all the study aardvarks were find emaciated , suggests that the Orycteropus afer really starve to death .
Without adequate emmet and white ant — which need a minimal level of grime moisture to survive — the aardvarks ran low on energy reserves , unable to maintain their center temperatures and recur to braving the hot sun just to keep all organization running . Until they could n’t any longer .
The study leave a sick peek into the futurity for anteater . mostly incapable of pull round the collateral effect of condition that are bear to be prosaic in the coming century , aardvark may vanish from vast swaths of their current range , or even peril experimental extinction . Worse still , the loss of aardvark could trigger a eye mask impression for African ecosystems . Aardvarks , with their ceaseless burrowing and excavating , are “ ecosystem engineers , ” modifying the strong-arm environment in a way that creates tax shelter and resources for loads of other creatures . topper do it when they dam up waterways , for lesson . The loss of these type of engineersin places like Australiahas already been indicate to damage ecosystem . There are many lifeforms that remain firm to recede from the calamity that is drought - have aardvark starvation , preschoolers learning their ABC ’s andmeme makersjust some of them .
If Africa continues to heat up and dry out out , as is expect in future 10 , less and less territorial dominion will be worthy for aardvarks , and their mountain range will substantially shrink . While it is possible some region that were previously too muddy and waterlogged for aardvarks to successfully inhabit could become hospitable as they dry out out , it would come at a loss of other ecosystem , and aardvarks would still have a greatly diminished bearing on the continent as former grasslands transition to deserts . The far-flung loss of aardvark is not wholly destiny , but their survival for the most part reckon on humanity deal climate change .
