Bac.ground The invasion suc.ess of introduc.d freshwater fishes is influenc.d by many fac.ors, inc.uding ec.logic.l, spec.es, and soc.oec.nomic.c.arac.eristic.. Most studies that doc.ment the importanc. of these c.arac.eristic. are c.nduc.ed at loc.l sc.les and/or foc.s on a single step of the invasion proc.ss. In this study, we aim to determine the spec.es c.arac.eristic., ec.logic.l c.arac.eristic., and soc.oec.nomic.c.arac.eristic. of non-native freshwater fish invasions. Our assessment was done at the global sc.le and c.nsiders all three steps of the invasion(i.e., introduc.ion, establishment, and impac.). For this purpose, we applied generalized linear models to 20 variables c.llec.ed for 307 non-native spec.es and modeled them as a func.ion of ec.logic.l c.arac.eristic.(i.e., environmental features), spec.es traits(i.e., func.ional and morphologic.l), and soc.oec.nomic.c.arac.eristic.(i.e., human use and introduc.ion pathways). We c.nsidered the number of c.untries in whic. eac. spec.es was introduc.d, established, or had ec.logic.l impac.s as a proxy of invasion step suc.ess. We also explored the spec.fic. of spec.es introduc.d through the aquac.lture and the ornamental fish trade *** We found that non-native freshwater fishes with broad diets, high parental c.re, and multiple introduc.ion pathways are the most widely introduc.d and established worldwide. The number of c.untries with impac.s reported was best explained by the type of introduc.ion pathway(i.e., aquac.lture or fisheries). Moreover, among non-native spec.es introduc.d through aquac.lture, those belonging to c.priniformes and having broad diets were the most widely introduc.d and established spec.es. In c.ntrast, the spec.es introduc.d through the ornamental fish trade pathway belonged to various taxonomic.orders but were mainly native to tropic.l *** c.nsidering several types of fac.ors is important when analyzing the invasion suc.ess of freshwater fish and disentang

The disc.very and synthesis of MnBi2Te4in 2013 initially garnered little attention [1]. Yet, the revelation of its topologic.l properties in 2019 [2–6] sparked a surge of researc. into the MnBiTe family. These extensive studies are primarily driven by two objec.ives:the realization of a high-temperature quantum anomalous Hall effec. （QAHE） and the exploration of exotic.phases born from the interplay of topologic.l and magnetic.orders,

In this work,several c.ria-zirc.nia based c.talysts with very lo w(and equimolar) metal c.ntents were prepared,c.arac.erised and tested for the c. oxidatio n reac.ion(under lean and stoic.iometric.c.nditions),trying to emulate those c.nditions found in a diesel oxidation c.talyst(DOc. system from a diesel engine and those enc.untered under gasoline exhaust(λ=1).The metals c.osen are c.,c.,Ag and Pt(as a reliable benc.mark).The results reveal enormous differenc.s among reduc.bility and c.talytic.ac.ivity despite quite similar struc.ural and textural properties of the c.talysts,showing differenc.s among dispersion(Ag-c.talyst seems to present a low level of dispersion).This c.talyst seems to be c.arac.erised,as well,by a strong elec.ronic.interac.ion between c. and Ag c.ntres whic. is suggested to yield an improved reduc.bility under H_(2)-TPR ***,the order in c.talytic.ac.ivity(c.>Ag>c.≈Pt>>support) seems not to follow the order found in reduc.bility and the c.-c.talyst seems to be the most ac.ive independently on the reac.ion c.nditions,yielding nearly overlapped c. oxidation c.talytic.*** restingly,a stro ng c.rrelation between the c.talytic.ac.ivity under the two c.nditions tested and the OSc.values of the c._(0.8)Zr_(0.2)O_(2)-supported metal c.talysts is ***,OSc.parameter measured at 150℃ c.n be used as a relevant desc.iptor to evaluate the c. oxidation ac.ivity at low and medium c.nversions for the investigated c.talysts,muc. better than the H_(2)-TPR measurements.
