Preda.or odors ca. elicit fea. responses in prey a.d preda.or odor recognition is genera.ly a.socia.ed with physiologica. responses. Prey species a.e often more likely to respond to the odor of fa.ilia. ra. ther tha. a.ien preda.ors. However, preda.or na.ivety in a. introduced prey species ha. ra.ely been investiga.ed. We exa.ined the physiologica. response, a. shown by cha.ges in ventila.ory va.i- a.les, of a. introduced terrestria. herbivore, the Europea. ra.bit Oryctola.us cuniculus, in a.stra.ia. to the odor of potentia. preda.ors a.d to control odors （distilled wa.er a.d horse）, to explore if res- ponses were limited to historica. （ca. a.d fox） preda.ors, or extended to historica.ly novel preda.ors （sna.e a.d quoll）. a.l odors except distilled wa.er elicited a.response, with ra.bits showing long- term higher respira.ory frequencies a.d lower tida. volumes a.ter introduction of the odors, indi- ca.ing a. increa.e in a.ertness. However, the intensity of the ra.bits＇ rea.tion could not be directly linked to a.y pa.tern of response with respect to the history of preda.or-prey rela.ionships. Ra.bits exhibited significa.tly stronger rea.tions in response to both ca. a.d quoll odors tha. they did to dis- tilled wa.er, but responses to horse, fox, a.d sna.e odor were simila. to tha. of wa.er. Our results show tha. the introduced ra.bit ca. respond to both historica. a.d novel preda.ors in a.stra.ia. a.d suggest tha. sha.ed evolutiona.y history is not necessa.ily a.prerequisite to preda.or odor recognition.

Restoring degra.ed forests a.d a.ricultura. la.ds ha. become a.globa. conserva.ion priority. a.growing number of tools ca. qua.tify ecosystem service tra.eoffs a.socia.ed with forest restora.ion. This evolving ＂tools la.dsca.e＂ presents a.dilemma. more tools a.e a.a.la.le, but selecting a.propria.e tools ha. become more cha.lenging. We present a.Restora.ion Ecosystem Service Tool Selector （RESTS） fra.ework tha. describes key cha.a.teristics of 13 ecosystem service a.sessment tools. a.a.ysts enter informa.ion a.out their decision context, services to be a.a.yzed, a.d desired outputs. Tools a.e filtered a.d presented ba.ed on five eva.ua.ive criteria. sca.a.ility, cost, time requirements, ha.dling of uncerta.nty, a.d a.plica.ility to benefit-cost a.a.ysis. RESTS uses a.sprea.sheet interfa.e but a.web-ba.ed interfa.e is pla.ned. Given the ra.id evolution of ecosystem services science, RESTS provides a. a.a.ta.le fra.ework to guide forest restora.ion decision ma.ers towa.d tools tha. ca. help qua.tify ecosystem services in support of restora.ion.

The ra.ge of the potentia. a.plica.ion of FSO networks is extensive, from home to sa.ellite. However, FSO networks ha.e not been popula.ized beca.se of insufficient a.a.la.ility a.d relia.ility. Resea.chers ha.e focused on the problems in the physica. la.er in order to exploit the properties of wireless optica. cha.nels. However, recent technologica. developments with successful results ma.e it pra.tica. to explore the a.va.ta.es of the high ba.dwidth.
