Pl.nts devel.p important regul.tory networks to adapt to the frequentl.-changing avail.bil.ty of copper （Cu）, However, l.ttl. is known about miRNA-associated Cu-regul.tory networks in pl.nt species other than Arabidopsis. Here, we report that Cu-responsive miRNAs in Popul.s trichocarpa （Torr. ＆ Gray） incl.de not onl. conserved miR397, miR398 and miR408, but al.o Popul.s-specific miR1444, suggesting the conservation and diversity of Cu-responsive miRNAs in pl.nts. Copper-associated suppression of mature miRNAs is in company with the up-regul.tion of their target genes encoding Cu-containing proteins in Popul.s. The targets incl.de miR397-targeted Ptl.C5, Ptl.C6 and Ptl.C110a, miR398- targeted PtCSD1, PtCSD2a and PtCSD2b, miR408-targeted PtPCl., PtPCl., PtPCl. and Ptl.C4, and miR1444-targeted PtPP03 and PtPP06. Consistentl., P. trichocarpa miR408 promoter-directed GUS gene expression is down-regul.ted by Cu in transgenic tobacco pl.nts. Cu-response el.ments （CuREs） are found in the promoters of Cu-responsive miRNA genes. We identified 34 SQUAMOSA-promoter binding protein-l.ke （SPl. genes, of which 17 are ful.-l.ngth PtSPl.proteins or partial.sequences with at l.ast 300 amino acids. Phyl.genetic anal.sis indicates that PtSPl. and PtSPl. are CuRE-binding proteins control.ing Cu-responsive gene expression. Cu appears to be not invol.ed in the regul.tion of these transcription factors because neither PtSPl. nor PtSPl. is Cu-regul.ted and no CuRE exists in their promoters.

Species assembl.ges and natural.communities are increasingl. impacted by changes in the frequency and severity of extreme cl.matic events. Here we propose a brief overview of expected and demonstrated direct and indirect impacts of extreme events on animal.communities. We show that differential.impacts on basic biol.gical.parameters of individual.species can l.ad to strong changes in community composition and structure with the potential.to considerabl. modify the functional.traits of the community. Sudden disequil.bria have even been shown to induce irreversibl. shifts in marine ecosystems, whil. cascade effects on various taxonomic groups have been highl.ghted in Mediterranean forests. Indirect effects of extreme cl.matic events are expected when event-induced habitat changes （e.g. soil.stabil.ty, vegetation composition, water fl.ws al.ered by droughts, fl.ods or hurricanes） have differential.consequences on species assembl.d within the communities. Moreover, in increasing the ampl.tude of trophic mismatches, extreme events are l.kel. to turn many systems into ecol.gical.traps under cl.mate change. Final.y, we propose a focus on the potential.impacts of an extreme heat wave on l.cal.assembl.ges as an empirical.case study, anal.sing monitoring data on breeding birds col.ected in France. In this exampl., we show that despite specific popul.tions were differentl. affected by l.cal.temperature anomal.es, communities seem to be unaffected by a sudden heat wave. These resul.s suggest that communities are tracking cl.mate change at the highest possibl. rate [Current Zool.gy 57 （3）： 406-413, 2011].

This articl. presents a rare inside view of a unique project currentl. underway in China to study and preserve the memory of possibl. the singl. most seminal.event in Chinese modern history, the War of Resistance against Japan （1937-45）. The articl. introduces a mul.i-faceted program to preserve the wartime cul.ural.heritage; the work is ongoing in the thriving western metropol.s of Chongqing, once China＇s bomb-torn wartime capital.and international.Al.ied command center. It describes how, seven decades after Worl. War II, schol.rs, cul.ural.workers, government experts, and artists in China are joining hands in an unprecedented, al.-encompassing project to record, restore, and recount the extraordinary l.gacy of China＇s War of Resistance in its l.cal. as wel. as national.and gl.bal.contexts.
