Abstract Leaf mechanical properties strongly influence leaf lifespan, plant–herbivore interactions, litter decomposition and nutrient cycling, but global patterns in their interspecific variation and underlyin...g mechanisms remain poorly understood. We synthesize data across the three major measurement methods, permitting the first global analyses of leaf mechanics and associated traits, for 2819 species from 90 sites worldwide. Key measures of leaf mechanical resistance varied c. 500–800-fold among species. Contrary to a long-standing hypothesis, tropical leaves were not mechanically more resistant than temperate leaves. Leaf mechanical resistance was modestly related to rainfall and local light environment. By partitioning leaf mechanical resistance into three different components we discovered that toughness per density contributed a surprisingly large fraction to variation in mechanical resistance, larger than the fractions contributed by lamina thickness and tissue density. Higher toughness per density was associated with long leaf lifespan especially in forest understory. Seldom appreciated in the past, toughness per density is a key factor in leaf mechanical resistance, which itself influences plant–animal interactions and ecosystem functions across the globe.show more

Notes
世界90カ所から2819種のデータを収集し、植物の葉の力学的性質（丈夫さ）を地球規模で評価しました。主な知見は以下の通りです。(1) 構造的強度は種間で500-800倍の違いがあることが分かりました。この変異の大きさは葉の厚さなどの変異（50倍程度）よりも一桁大きく、葉の性質の違いを特徴づける重要な形質の一つと言えます。 (2)構造的強度が種によって大きく異なる原因は、従来考えられてきた葉の厚さや密度の違いよりも、むしろ葉を構成している繊維等の質的な違いが重要であることが分かりました。(3)「熱帯では温帯に比べ、植物を食べる生物が多いため、葉がより丈夫である」という仮説がありましたが(e.g. Coley & Aide)、検証した結果、そのような傾向はないことが分かりました。(4) 乾燥地では葉が厚くなる傾向があり、構造的強度もそれに伴って増加する傾向が見られました。(5) 葉の構造的強度の変異の5-7割は、同じ環境で共存する植物種の間に見られました。つまり、同所的に共存する種の間にも様々な戦略があることを定量的に示しています。(6) 暗い環境では葉が薄くなり、構造的強度も低下するにも関わらず、葉の寿命は長いというパラドックスが知られていますが、今回の解析から、暗い環境の葉は薄いわりに強く、それが長寿命に繋がっていることが分かりました。
