长期以来,人们普遍认为热带和亚热带树种的形成层生长是连续的,对气候变化不敏感(Lieberman,Lieberman,Hartshorn,& Peralta,1985;理查兹,1996)。然而,最近的研究表明,许多(如果不是大多数)热带和亚热带物种确实对气候变化做出反应,并能形成每年的树木年轮,特别是在降雨季节性明显的地区(Fichtler,海勒,& Worbes,2010; Gebrekirdings,Bräuning,Sass-Klassen,& Mbow,2014; Gebrekirdings,Mitlöhner,Teketay,& Worbes,2008; Gourlay,1995 a,B; Gourlay & Grime,1994; Mbow,Chhin,Sambou,&斯科莱,2013; Nicolini,Tarchiani,Saurer,& Cherubini,2010; Rozendaal Danaë & Zuidema,2011; Schöngart,Orthmann,Hennenberg,Porembski,& Worbes,2006; Steenkamp,2000; Steenkamp,Vogel,Fuls,货车Rooyen,&货车Rooyen,2008; Trouet,Ehran,& Beeckman,2010; Worbes,1995,1999; Worbes,Staschel,Roloff,& Junk,(2003年)许多萨凡纳树种的年龄测定似乎是可能的,这一事实使得热带和亚热带树木年代学对于了解萨凡纳草原至关重要。生态系统动态和灌木入侵的原因和影响(Southworth等人,2013; Steenkamp等人,2008年)。了解这些动态的基础是树种木材解剖特征的信息。
For a long time, a widely held notion has been that cambial growth in tropical and subtropical tree species is continuous without any sensitivity to climatic variations (Lieberman, Lieberman, Hartshorn, & Peralta, 1985; Richards, 1996). More recently, however, studies have shown that many, if not most, tropical and subtropical species do respond to climatic variations and can form annual tree-rings, especially at locations with pronounced seasonality of rainfall (Fichtler, Helle, & Worbes, 2010; Gebrekirstos, Bräuning, Sass-Klassen, & Mbow, 2014; Gebrekirstos, Mitlöhner, Teketay, & Worbes, 2008; Gourlay, 1995a, b; Gourlay & Grime, 1994; Mbow, Chhin, Sambou, & Skole, 2013; Nicolini, Tarchiani, Saurer, & Cherubini, 2010; Rozendaal Danaë & Zuidema, 2011; Schöngart, Orthmann, Hennenberg, Porembski, & Worbes, 2006; Steenkamp, 2000; Steenkamp, Vogel, Fuls, van Rooyen, & van Rooyen, 2008; Trouet, Esper, & Beeckman, 2010; Worbes, 1995, 1999; Worbes, Staschel, Roloff, & Junk, 2003).The fact that age determination of many savannah wood species seems possible makes tropical and subtropical dendrochronology essential for the understanding of savannah ecosystem dynamics and the cause and the influence of bush encroachment (Southworth et al., 2013; Steenkamp et al., 2008). The basis for the comprehension of these dynamics is information on wood anatomical features of species.
