Environmenta. wa.ming pla.es physiologic.0} c.nstra.nts on orga.isms, whic. ma. be mitiga.ed by their feeding beha.ior. Theory predic.s tha. c.nsumers should inc.ea.e their feeding selec.ivity for more energetic.0}ly va.ua.le resourc.s in wa.mer environments to offset the disproportiona.e inc.ea.e in meta.olic.dema.d rela.ive to ingestion ra.e. This ma. a.so result in a.c.a.ge in feeding stra.egy or a.shift towa.ds a.more spec.a.ist diet. This study used a.na.ura. wa.ming experiment to investiga.e tempera.ure effec.s on the feeding selec.ivity of three freshwa.er invertebra.e gra.ers： the sna.l Ra.ix ba.thic.0} the bla.kfly la.va.Simulium a.reum, a.d the midgefly la.va.Eukiefferiella.minor. c.esson＇s Selec.ivity Index wa. used to c.mpa.e the proportiona. a.unda.c. of dia.om spec.es in the guts of ea.h invertebra.e spec.es with c.rresponding roc. biofilms sa.pled from strea.s of different tem- pera.ure. The sna.ls bec.0}e more selec.ive in wa.mer strea.s, c.oosing high profile epilithic.dia.oms over other guilds a.d feeding on a.lower diversity of dia.om spec.es. The bla.kfly la.va. a.pea.ed to switc. from a.tive c.llec.or ga.hering of sessile high profile dia.oms to more pa.sive filter feeding of motile dia.oms in wa.mer strea.s. No c.a.ges in selec.ivity were observed for the midgefly la.va., whose diet wa. representa.ive of resourc. a.a.la.ility in the environment.
