退耕地幼龄台湾桤木(Alnus formosana)根系结瘤

结瘤量能直观地反映林木的固氮能力,根瘤是植物根系研究的核心内容之一。研究退耕还林地内林木结瘤可以为林地培肥和经营提供有益的借鉴。以四川省广元、北川、平武和丹棱4个地区退耕地内生长良好的幼龄台湾桤木为研究对象,对其根系结瘤情况及其与土壤养分含量的关系进行研究。结果表明：各地区台湾桤木根瘤的外观形态差异不大,结构紧密,呈珊瑚状,直径最小为2mm,最大达到30mm;台湾桤木根瘤生物量变化范围为2．59～132．14g·株^-1;水平分布主要集中在距树干0～50cm,垂直分布集中在0～20cm土层;50．4％～92．5％的根瘤着生在细根（d≤2mm）上,大体积（15～30mm）根瘤多着生在根颈处;单株根瘤生物量与土壤水解氮含量呈显著负相关,而与土壤有效磷含量呈显著正相关（P〈0．05）。     

桂西南岩溶地区珍稀濒危树种育苗与造林初报

2003～2005年,在广西平果县龙何示范区对10种岩溶珍稀濒危树种的育苗和造林的技术及效果进行了初步研究。试验结果表明,在苗圃育苗的9个树种中,仪花和广西顶果木的发芽率不足50%,其他树种则在70%以上;蒜头果有轻微性的根结线虫危害,其他树种的病虫害很少,大多数树种苗木均表现出早期生长慢、后期生长快的势头。在直播造林中,苏木的效果最好,蒜头果次之,而蝴蝶果、广西顶果木和海南椴等很差;任豆、东京桐等5个树种的植苗造林成活率超过75%,其中任豆和广西顶果木的株高平均年生长量大于40cm,东京桐、蝴蝶果和海南椴等树种则小于25cm。     

不同光环境对桤木幼苗生长和光合特性的影响

通过设置3个光照强度(100%、56.2% 和12.5%),模拟森林幼苗生长的旷地(采伐迹地)、林窗和林下光环境,研究不同光照强度对外来种台湾桤木和乡土种四川桤木幼苗的生长、光合特性以及生物量积累与分配的影响.结果表明： 低光环境限制了两种桤木幼苗形态指标的增长,适当遮荫的林窗环境比旷地更有利于幼苗的生长.台湾桤木幼苗具有较高的比叶面积和相对生长速率,较大的单叶面积、叶长、叶宽、株高和基径,较少的叶片数和较低的叶面积比、叶柄长.低光环境下,台湾桤木幼苗的最大净光合速率、光饱和点和表观光量子效率较高,光补偿点和暗呼吸速率较低.随着光照强度的降低,台湾桤木幼苗具有更高的根生物量比和更低的叶生物量比;四川桤木幼苗则相反,加剧了动物取食和机械损伤的风险.     

陇东旱塬苹果根系分布规律及生理特性对地表覆盖的响应

为探明陇东旱塬区不同覆盖物对苹果园土壤理化性状、根系分布及根系生理活性的影响,以14年生苹果树为试材,采用土壤剖面分层取样法,调查根系空间分布,并对根系生物量、根长、表面积等进行分析,测定根系活力、抗氧化酶类、活性氧代谢等相关生理指标,同时测定不同深度土层土壤容重、孔隙度等.结果表明: 覆草可有效增大土壤含水量、孔隙度、有机质含量,增幅分别为2.7%～11.6%、3.2%～27.7%、5.1%～36.0%,但土壤容重降低,为清耕(CK)的88.7%～96.4%.CK根系主要分布在距树干30～120 cm范围内的0～60 cm深土层中;覆草、覆膜处理主要分布在距树干0～150 cm、0～60 cm水平范围内的0～100 cm深土层中,以20～40 cm根系最为密集;覆膜处理细根总量仅为CK的96.4%,根系水平分布范围较CK有所减小,0～60 cm内细根占根系总量的51.6%.不同覆盖处理显著增强0～80 cm土层根系活力及抗氧化酶活性,其中覆草处理根系活力为CK的111.3%～136.7%.综合分析根系生长分布与生理活性、土壤理化性状等,认为覆草处理是陇东旱塬区苹果园较为适宜的地表覆盖方式.

施肥对台湾桤木-扁穗牛鞭草复合模式下桤木细根形态特征、生物量及组织碳氮含量的影响

细根具有良好的可塑性, 不同根序等级的细根会表现不同的策略来适应土壤资源有效性的改变, 了解各级细根对土壤资源有效性的可塑性反应对认识细根的养分和水分吸收规律、预测碳(C)在地下的分配特点具有重要意义。该文以四川省丹陵县台湾桤木(Alnus formosana)-扁穗牛鞭草(Hemarthria compressa)复合模式为研究对象, 采用施肥处理, 应用土柱法采样, 探讨了施肥对台湾桤木-扁穗牛鞭草模式土壤表层(0-10 cm)和亚表层(10-20 cm)台湾桤木1-5级细根的生物量、形态特征(直径、比根长)、全C和全氮(N)含量的影响。结果表明: (1)台湾桤木1-5级细根直径随根序的增大而增加, 施肥降低土壤表层台湾桤木各级细根直径而增加了土壤亚表层台湾桤木各级细根直径; 台湾桤木1-5级细根比根长则随根序的增加而减小, 施肥增加了台湾桤木各级细根的比根长, 且施肥极显著增加了表层和亚表层台湾桤木前三级细根的比根长(p < 0.01)。(2)台湾桤木1-5级细根生物量均随土层深度的增加而减小, 施肥减少了台湾桤木各个土层各级细根生物量, 且显著降低了台湾桤木前三级细根生物量占总生物量的比例(p < 0.05), 而增加了4、5级细根生物量。(3)台湾桤木3级细根全C最大, 1级根最小, 且土壤表层台湾桤木各级细根全C含量大于亚表层; 施肥降低了台湾桤木各级细根全C含量, 但影响并不显著(p > 0.05)。台湾桤木细根全N含量随根序的增加而降低, 且土壤表层1-5级细根全N含量均高于亚表层; 施肥极显著(p < 0.01)增加了土壤表层1级细根及亚表层1、2级细根的全N含量, 而对于3-5级细根全N含量则影响不显著(p > 0.05)。以上结果显示, 当土壤资源有效性变化时, 各级根序细根会作出不同的可塑性反应, 且施肥对各级细根的影响主要表现在低级根上。     

不同光环境对桤木幼苗生长和光合特性的影响

通过设置3个光照强度(100％、56.2％和12.5％),模拟森林幼苗生长的旷地(采伐迹地)、林窗和林下光环境,研究不同光照强度对外来种台湾桤木和乡土种四川桤木幼苗的生长、光合特性以及生物量积累与分配的影响.结果表明:低光环境限制了两种桤木幼苗形态指标的增长,适当遮荫的林窗环境比旷地更有利于幼苗的生长.台湾桤木幼苗具有较高的比叶面积和相对生长速率,较大的单叶面积、叶长、叶宽、株高和基径,较少的叶片数和较低的叶面积比、叶柄长.低光环境下,台湾桤木幼苗的最大净光合速率、光饱和点和表观光量子效率较高,光补偿点和暗呼吸速率较低.随着光照强度的降低,台湾桤木幼苗具有更高的根生物量比和更低的叶生物量比;四川桤木幼苗则相反,加剧了动物取食和机械损伤的风险.     

距树干不同距离处华北落叶松人工林细根生物量分布特征及季节变化

 该文研究了华北落叶松(Larix principis-rupprechtii)人工林细根生物量水平分布和季节变化特征。采用钻土芯法(土钻内径7.0 cm), 在距树干20、50和100 cm处设取样点, 每个样点处分3层(0~10、11~20和21~30 cm)钻取土芯, 取样时间为5、7、9和10月。华北落叶松人工林细根(≤2 mm)生物量全年平均值为224.89 g&#8226;m^–2, 在水平分布上表现为100 cm处细根生物量最大(244.20 g&#8226;m^–2), 其次为20 cm处(221.03 g&#8226;m^–2), 50 cm处最少(209.45 g&#8226;m^–2)。在0~30 cm土层, 总细根(包括活跟和死根)生物量季节变化范围在169.67~263.09 g&#8226;m^–2之间, 9月细根生物量最大, 5月细根生物量最少。0~10 cm土层细根生物量季节变化差异显著(p＜0.05), 11~20和21~30 cm差异不显著(p＞0.05)。距树干100和20 cm处(0~10 cm土层), 细根生物量的季节变化差异明显(p＜0.05), 9月总细根生物量最大(172.82和185.68 g&#8226;m^–2), 5月总细根生物量最少(69.28和73.47 g&#8226;m^–2); 50 cm处季节变化差异不明显(p＞0.05)。细根生物量分布和季节变化不仅受土壤垂直格局影响同时也与距树干不同水平距离有很大的关系。     

传统农业生态系统中桤木改良土壤效应研究综述

桤木(Alnus nepalensis)是一种重要的非豆科固氮植物,广泛分布于喜马拉雅山脉东部地区。在东南亚地区的传统农业生态系统中,多用桤木作为休耕树种,或将其与农作物间作。桤木根瘤固氮量随季节和年龄而变化,在桤木-小豆蔻(Elettaria cardamomum)系统中15年达到高峰(155 kg·hm^-2);桤木通过共生固氮对系统产生的氮增加量在纯桤木林中7年达到高峰(117 kg·hm^-2)。桤木与农作物间作可显著提高农作物的产量,桤木-小豆蔻立地上小豆蔻的经济产量是在森林-小豆蔻立地上的2.2倍。桤木休闲地的休闲效果明显好于自然休闲地,其地上部分生物量在休闲6年后是自然休闲地的4倍,N蓄积量是自然休闲地的3倍,P、K蓄积量是自然休闲地的2倍。桤木根系特征似乎最适合混农林系统,其细根生物量(FRB)集中于土壤剖面上层10 cm范围内,在此范围内,FRB在“树+农作物”间作条件下比在“只有树”条件下高5%;在两种立地条件下,60%以上的细根都分布于树干周围0.5 m内,大部分木质根(直径>0.5 mm)都分布于土壤上层0~10 cm处,长度都不超过1 m。桤木可加速系统的养分循环。桤木凋落物降解速率比非固氮植物快,并且与其它植物凋落物混合后的降解速率与自身凋落物降解速率一样快。在传统刀耕火种系统中,用桤木替代自然林休闲在3~6年内即可恢复土壤肥力,改善土壤理化性质,显著缩短休闲周期。该文综述了近30年来桤木在传统农业生态系统中改良土壤效应的研究成果,以提高人们对桤木的生态作用的重视程度,使人们更好地将桤木利用到农业生态系统中,达到发展山区农业和保护生态环境双赢的目的。     

根际促生菌对石漠化地区造林苗木的促生效应

西南岩溶石漠化山区水土流失严重、养分贫瘠,导致植被恢复困难。为探究固氮菌对岩溶石漠化地区造林苗木的生长促进效应,该文以广西石漠化地区常见造林树种香樟、任豆、喜树和台湾相思苗木为材料,利用平板稀释法从石漠化乡土植物根际土壤筛选固氮菌,通过测定固氮酶活性及鉴定固氮菌菌种,选择固氮酶活性较高的菌种制成复合菌剂接种到试验苗木进行盆栽试验。结果表明:共筛选得到6株具有固氮能力的根际促生菌,分别属于根瘤菌属(Rhizobium)、中华根瘤菌属(Sinorhizobium)和黄杆菌属(Flavobacterium),其中归类为根瘤菌属的3株固氮菌酶活性较高。复合菌剂接种试验表明接种固氮菌对造林苗木的生长具有明显促进作用。与未接种处理相比,接种处理苗木的株高、叶面积、生物量以及叶绿素含量均显著增长;同时苗木的氮、磷、钾含量也有不同程度的增加。其中,香樟、任豆、喜树和台湾相思的氮含量分别提高了28.9%、53.1%、37.0%和31.6%;香樟、台湾相思的磷含量分别增加了25.6%和42.5%;任豆、台湾相思的钾含量分别增加了57.5%和49.7%。接种石漠化乡土固氮菌能够显著促进造林苗木生长和养分含量,在石漠化植被修复中具有较好的应用前景。

Stratigraphy, artefact industries and hominid associations for Sterkfontein, member 5

A revised stratigraphy for the early hominid site of Sterkfontein (Gauteng Province, South Africa) reveals a complex distribution of infills in the main excavation area between 2.8 and 1.4 m.y.a, as well as deposits dating to the mid to late Pleistocene. New research now shows that the Member 4 australopithecine breccia (2.8-2.6 Ma) extends further west than was previously thought, while a late phase of Member 4 is recognized in a southern area. The artefact-bearing breccias were defined sedimentologically as Member 5, but one supposed part of these younger breccias, the StW 53 infill, lacks in situ stone tools, although it does appear to post-date 2.6 Ma when artefacts first appear in the archaeological record. The StW 53 hominid, previously referred to Homo habilis, is here argued to be Australopithecus. The first artefact-bearing breccia of Member 5 is the Oldowan Infill, estimated at 2-1.7 Ma. It occupies a restricted distribution in Member 5 east and contains an expedient, flake-based tool industry associated with a few fossils of Paranthropos robustus. An enlarged cave opening subsequently admitted one or more Early Acheulean infills associated in Member 5 west with Homo ergaster. The artefacts attest to a larger site accumulation between ca. 1.7 and 1.4 Ma, with more intensive use of quartzite over quartz and a subtle but important shift to large flakes and heavier-duty tools. The available information on palaeoenvironments is summarized, showing an overall change from tropical to sub-tropical gallery forest, forest fringe and woodland conditions in Member 4 to more open woodland and grassland habitats in the later units, but with suggestions of a wet localized topography in the Paranthropus -bearing Oldowan Infill.

Paleosols and paleoenvironments of the middle Miocene,Maboko Formation,Kenya

The middle Miocene (15 Ma) Maboko Formation of Maboko Island and Majiwa Bluffs, southwestern Kenya, has yielded abundant fossils of the earliest known cercopithecoid monkey (Victoriapithecus macinnesi), and of a kenyapithecine hominoid (Kenyapithecus africanus), as well as rare proconsuline (Simiolus leakeyorum, cf. Limnopithecus evansi) and oreopithecine apes (Mabokopithecus clarki, M. pickfordi), and galagids (Komba winamensis). Specific habitat preferences can be interpreted from large collections of primate fossils in different kinds of paleosols (pedotypes). Fossiliferous drab-colored paleosols with iron-manganese nodules (Yom pedotype) are like modern soils of seasonally waterlogged depressions (dambo). Their crumb structure and abundant fine root-traces, as well as scattered large calcareous rhizoconcretions indicate former vegetation of seasonally wet, wooded grassland. Other fossiliferous paleosols are evidence of nyika bushland (Ratong), and early-successional riparian woodland (Dhero). No fossils were found in Mogo paleosols interpreted as saline scrub soils. Very shallow calcic horizons (in Yom, Ratong, and Mogo paleosols) and Na-montmorillonite (in Mogo) are evidence of dry paleoclimate (300-500 mm MAP=mean annual precipitation). This is the driest paleoclimate and most open vegetation yet inferred as a habitat for any Kenyan Miocene apes or monkeys. Victoriapithecus was abundant in dambo wooded grassland (Yom) and riparian woodland (Dhero), a distribution like that of modern vervet monkeys. Kenyapithecus ranged through all these paleosols, but was the most common primate in nyika bushland paleosols (Ratong), comparable to baboons and macaques today. Mabokopithecus was virtually restricted to riparian woodland paleosols (Dhero), and Simiolus had a similar, but marginally wider, distribution. Habitat preferences of Mabokopithecus and Simiolus were like those of modern colobus monkeys and mangabeys. A single specimen of Komba was found in dambo wooded grassland paleosol (Yom), a habitat more like that of the living Senegal bushbaby than of rainforest galagids. A shift to non-forest habitats may explain the terrestrial adaptations of Victoriapithecus, basal to the cercopithecid radiation, and of Kenyapithecus, basal to the hominoid radiation. Both taxa are distinct from earlier Miocene arboreal proconsulines, oreopithecines and galagids.     

基于分子证据确认秦岭藤属与驼峰藤属(夹竹桃科)的系统位置

秦岭藤属(Biondia Schltr.)是中国特有属,约13种,驼峰藤属(Merrillanthus Chun & Tsiang)是仅在我国与柬埔寨分布的单种属,目前两个属均被归并到白前属(Vincetoxicum Wolf),由于取样和系统发育分析尚存一些欠缺,因此其系统位置和归属尚需进一步确认。该文使用2个核糖体基因序列片段(ITS、ETS)、5个叶绿体基因序列片段(psbA-trnH、trnG、trnL、trnL-F、trnT-L),以及二者的合并数据,重建娃儿藤亚族(Tylophorinae)(包含属的模式秦岭藤 [B. chinensis Schltr.=V. shaanxiense(Schltr.)Meve & Liede]与驼峰藤 [M. hainanensis Chun & Tsiang=V. hainanense(Chun & Tsiang)Meve, H. H. Kong & Liede])的系统发育树。结果表明:秦岭藤属与驼峰藤属均包含在白前属中,秦岭藤与青龙藤 [B. henryi(Warb.)Tsiang & Li=V. henryi(Warb.)Meve & Liede]互为姐妹类群,并与V. kawaroense Meve & Liede聚为一支,而黑水藤 [B. insignis Tsiang=V. insigne(Tsiang)Meve, H. H. Kong & Liede]在另一分支中(亚热带分支Subtropical Clade); 驼峰藤属与V. cissoides(Blume)Kuntze和V. philippicum Meve, Omlor & Liede聚为一支。核糖体和叶绿体基因数据均支持秦岭藤属与驼峰藤属归并入白前属,但秦岭藤属为多系,尚需收集更多种类和数据合并分析,深入探讨归并后白前属的种间系统关系和位置。     

Reconstructing the history of Campanulaceae with a Bayesian approach to molecular dating and dispersal–vicariance analyses

We reconstruct here the spatial and temporal evolution of the Campanula alliance in order to better understand its evolutionary history. To increase phylogenetic resolution among major groups (Wahlenbergieae–Campanuleae), new sequences from the rbcL region were added to the trnL-F dataset obtained in a previous study. These phylogenies were used to infer ancestral areas and divergence times in Campanula and related genera using a Bayesian approach to molecular dating and dispersal–vicariance analyses that takes into account phylogenetic uncertainty. The new phylogenetic analysis confirms Platycodoneae as the sister group of Wahlenbergieae–Campanuleae, the two last ones inter-graded into a well-supported clade. Biogeographic and dating analyses suggest that Western Asia and the Eastern Mediterranean have played a major role as centers of migration and diversification within the Campanula alliance, probably in relation to the intense orogenic activity that took place in this region during the Late Neogene, and that could have promoted isolation and allopatric speciation within lineages. Diversification rates within several Campanula lineages would have increased at the end of the Miocene, coinciding with the Messinian Stage. Strong selective pressures from climate changes and the expansion of mountainous regions during this period are suggested to explain the adaptation to drought, cold or disturbed environments observed in many Campanula species. Several independent long-distance dispersal events to North America are inferred within the Rapunculus clade, which seem to be related to high ploidy levels.
