Habi­tat, not cli­mate

Down to Earth - - SCIENCE -

TERRE STRIAL VER­TE­BRATE S are more abun­dant on earth than aquatic ones. Very lit­tle is known about how or why this dif­fer­ence oc­curs. Re­search now sug­gests that this vari­a­tion has been brought about by the habi­tat in which the an­i­mals live— groups liv­ing on land pro­lif­er­ate more rapidly than those in wa­ter. There is a higher rate of ex­tinc­tion in both marine and fresh­wa­ter en­vi­ron­ments, as an­i­mals in th­ese habi­tats do not have the op­tion to mi­grate and es­cape. Bi­ol­ogy Let­ters, July 22
