Hu­man ac­tiv­ity caus­ing world’s mam­mals to be­come in­creas­ingly noc­tur­nal

TechLife Australia - - THE WALL -


As the hu­man pop­u­la­tion con­tin­ues to grow, so does the re­quire­ment for mam­mal species to adapt their be­hav­iours to sur­vive. A re­cent study pub­lished in the jour­nal Sci­ence ex­plores the changes to the daily ac­tiv­ity pat­terns of mam­mals in re­sponse to hu­man ac­tiv­ity. The global re­search project fo­cused on 62 species larger than one kilo­gram across six con­ti­nents. The team from the Uni­ver­sity of Cal­i­for­nia at Berke­ley found that, on av­er­age, these mam­mals in­creased their night­time ac­tiv­ity by 36% in re­sponse to hu­man dis­tur­bance. This grow­ing be­havioural change could have many neg­a­tive con­se­quences. As mam­mals be­gin to shift to noc­tur­nal pat­terns the fear is that these an­i­mals’ for­ag­ing or hunt­ing be­hav­iour will be dis­rupted, leav­ing them more vul­ner­a­ble to pre­da­tion and in­creased com­pe­ti­tion from other species.
