Recent metaanalyses have shown that the effects of climate change are detectable and significant in their magnitude, but these studies have emphasized the utility of looking for largescale patterns without necessarily understanding the mechanisms underlying these changes. As the editors described in their introduction, besides ongoing progress in dissecting immune recognition and signaling pathways, studies have revealed differences at.
