The challenge of a Siberian bluegrass (Poa) phylogeny. 西伯利亚蓝草(Poa)系统发育的挑战。
Pub Date : 2010-01-01 DOI: 10.5642/ALISO.20102801.03
M. Olonova
In Siberia, the bluegrass genus (Poa) comprises 43 species and 61 subspecies in 12 sections. Diverse modes of speciation, including polyploidy and hybridization, have led to reticulate evolution and adaptive radiation. Cladistic methods that ignore hybridization and reticulate evolution may not be appropriate for morphological data. The number of morphological characters suitable for bluegrass analysis is limited, a majority does not have clear adaptive significance, and the character states cannot be readily polarized, rendering phylogenetic reconstruction very difficult in this group. Other methods of estimating phylogenetic relationships should be used to test hypotheses about relationships and hybridization. Biochemical and molecular data, as well as karyological, phytogeographical, and other lines of evidence should be combined to establish an explicit and testable hypothesis of the sequence of character state changes acquired during biotic differentiation.
在西伯利亚,蓝草属(Poa)包括12个区43种和61亚种。多种物种形成模式,包括多倍体和杂交,导致了网状进化和适应性辐射。忽略杂交和网状进化的枝源分类方法可能不适用于形态学数据。适合蓝草分析的形态性状数量有限,大多数没有明确的适应意义,而且性状状态不能轻易极化,使得该类群的系统发育重建非常困难。其他估计系统发育关系的方法应该用来检验关于关系和杂交的假设。生物化学和分子数据,以及核学、植物地理学和其他证据应该结合起来,建立一个明确的、可测试的假设,即在生物分化过程中获得的特征状态变化序列。

The Sierra San Pedro Mártir (SSPM) is the highest mountain range in Baja California, Mexico, the summit of Picacho del Diablo peak attaining 3095 meters. An annotated checklist describes the vascular flora of the SSPM high country, defined here as above 1800 m. It comprises almost 500 species in 251 genera and 78 families. The high country is dominated by coniferous forest species known from montane California and Arizona whose southern ranges terminate in the SSPM. The annotated checklist identifies 453 species in 236 genera as indigenous, of which 23 species and one variety are endemic to the SSPM. Over 30 species are unreported from Alta California but occur in regions northeast of Baja California. The climate, vegetation and biogeography of the range are described. Botanical explorations to the area since 1893 are outlined with reference to collectors, their collections, and herbaria where specimens are housed. For each species, the checklist cites one to several collections, months in flower, and known distribution ranges. Asteraceae is the most speciose of the twelve largest families, and Juncus contributes the most indigenous species, followed by Carex and Muhlenbergia. Listed separately are species from chaparral or desert scrub just below the 1800 m limit that are thought to extend into the high country but for which no records exist at this time.
圣佩德罗山脉Mártir (SSPM)是墨西哥下加利福尼亚州最高的山脉,Picacho del Diablo峰的顶峰达到3095米。一份有注释的清单描述了SSPM高海拔地区的维管植物群,这里的定义是1800米以上。它包括78科251属近500种。高海拔地区主要是针叶林物种,已知来自加利福尼亚州和亚利桑那州的山区,其南部范围终止于SSPM。带注释的清单鉴定出本地236属453种,其中SSPM特有23种和1个变种。超过30种未在上加利福尼亚报告,但分布在下加利福尼亚州东北部地区。描述了该地区的气候、植被和生物地理。自1893年以来,对该地区的植物探索概述了参考收藏家,他们的收藏品和标本所在的植物标本室。对于每个物种,清单上都列出了一到几个品种,花期和已知的分布范围。在12个最大的科中,菊科是种类最多的,菊科是最多的本土物种,其次是苔属和Muhlenbergia。单独列出的物种来自1800米以下的灌木丛或沙漠灌丛,它们被认为延伸到高地,但目前没有记录。

Travis Columbus, James P. Smith
New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festuca, is here subsumed into Festuca, and the circumscription of Stipa is expanded to include all Stipeae (native and nonnative) in California. In Stipeae, most currently recognized genera are not monophyletic. Attaining monophyly while bearing in mind identification for persons not expert in Stipeae were the guiding principles in expanding the circumscription of Stipa. Newly recognized are: Elymus elymoides var. californicus, E. elymoides var. hordeoides, Festuca perennis, Hilaria subgen. Pleuraphis, Muhlenbergia brevigluma,M. diandra,M. imperfecta,M. multiflora,M. paniculata,M. phleoides,M. plumiseta,M. spatha, M. tricholepis, M. uniseta, Schismus barbatus var. arabicus, Stipa chaetophora, S. divaricata, S. exigua, S. mauritanica, and S. purpurata.
本文为即将修订的《杰普森手册》验证了加州十个草(禾本科)分类群的新组合和名称。此外,在最近的分子系统发育研究的指导下,本文将10种非加利福尼亚草转移到Muhlenbergia (Chloridoideae: Cynodonteae),以实现属的单系化。从系统发育角度来看,Lolium一直被认为嵌套在Festuca中,在这里被纳入了Festuca,而Stipa的范围扩大到包括加州所有的Stipeae(本地和非本地)。在Stipeae中,大多数目前公认的属不是单系的。扩大针茅属范围的指导原则是在考虑非针茅属专家身份的同时实现单性。新发现的有:加州elymoides变种,hordeoides变种elymoides, Festuca perennis, Hilaria亚群。Pleuraphis, Muhlenbergia brevigluma,M。安德拉,M。天空,M。野蔷薇,M。香,M。phleoides, M。plumiseta, M。spatha, M. tricholepis, M. uniseta, S. barbatus vara arabicus, Stipa chaetophora, S. divaricata, S. exigua, S. mauritanica和S. purpurata。

Non-random vessel distribution in woods: patterns, modes, diversity, correlations. 森林中的非随机容器分布:模式、模式、多样性、相关性。
Pub Date : 2009-01-01 DOI: 10.5642/ALISO.20092701.04

Vessel grouping is a form of non-random distribution that becomes functionally valuable when the background consists of non-conductive imperforate tracheary elements (fiber-tracheids and libriform fibers); ungrouped vessels, randomly placed, often occur in an all-tracheid background. Types of vessel grouping are described and illustrated: diagonal, tangential, radial, median radial bands, and growth rings. Other non-random distributions considered include degrees and kinds of cable construction, patchy vessel distributions, vessel displacement related to succulence, and patterns involving successive cambia. Non-random vessel distributions inevitably involve non-random placement of imperforate tracheary elements, so that a parallel set of mechanical adaptations is often simultaneously achieved. Correlations between various types of non-random vessel patterns and possible physiological factors are hypothesized. Most correlations involve enhanced conductive safety, but vessel distribution related to water and photosynthate storage, resistance to torsion, and increased longevity of xylem are cited. Non-randomness of vessels is a source of diversity in wood structure that can be achieved readily (as growth rings show) and polyphyletically. These modifications offer numerous ways in which wood histology can be repatterned for probable adaptations in conductive physiology, mechanical strength, and storage capability, perhaps by means of regulatory genes. Grouping of vessels into vascular bundles in primary xylem of stems and leaves in dicots is a form of non-randomness, and the significance of vascular bundles (as opposed to steles) as adaptive forms of organization is considered briefly. Monocots differ from dicots in rarely having division of labor in tracheary elements within an organ, but monocots exhibit tradeoffs in which conductive efficiency (vessel presence in an organ) and conductive safety (tracheids but no vessels in an organ) can be achieved within a single plant.
血管分组是一种非随机分布形式,当背景由不导电的无穿孔气管元件(纤维管状和纤状纤维)组成时,它在功能上变得有价值;无组的血管,随机放置,经常出现在全管胞背景。描述和说明了血管分组的类型:对角线、切向、径向、中径向带和生长环。其他考虑的非随机分布包括缆索构造的程度和种类、斑块状血管分布、与肉质相关的血管位移以及涉及连续形成层的模式。非随机血管分布不可避免地涉及非随机放置的无穿孔气管元件,因此通常同时实现一套平行的机械适应。各种类型的非随机血管模式和可能的生理因素之间的相关性进行了假设。大多数相关性涉及到增强的导电安全性,但也提到了与水和光合产物储存有关的容器分布、抗扭转能力和木质部寿命延长。容器的非随机性是木材结构多样性的一个来源,这种多样性可以很容易地(如生长环所示)和多系性地实现。这些修饰提供了多种方法,木材的组织学可以重新塑造,以适应传导生理、机械强度和储存能力,这可能是通过调控基因来实现的。二穗茎叶初生木质部的维管束是一种非随机性的形式,本文简要地讨论了维管束(相对于柱)作为适应性组织形式的意义。单子叶植物与双子叶植物的不同之处在于,单子叶植物在一个器官中很少有管状细胞的分工,但单子叶植物在传导效率(器官中有导管)和传导安全性(器官中有管状细胞但没有导管)之间表现出权衡。

Descriptive Anatomy and Evolutionary Patterns of Anatomical Diversification in Adenia (Passifloraceae) 西番莲科腺属植物解剖多样性的描述解剖及进化模式
Pub Date : 2009-01-01 DOI: 10.5642/ALISO.20092701.03
David J Hearn
To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; and well-developed axial parenchyma. Multiple cambial variants were observed, including anomalous parenchyma proliferation, anomalous vascular strands, successive cambia, and a novel type of intraxylary phloem. Successive cambia, trichomes, dermal features, and intraxylary phloem were synapomorphic for particular clades, whereas most traits were homoplastic. Several anatomical features of Adenia are consistent with xeromorphy. Repeated loss and gain of cuticularized, photosynthetic mature stems, narrow vessel elements, highly aggregated vessels, and other features indicative of xeromorphy reveal labile evolution of ecologically significant anatomical features, whereas features that are characteristic of the liana life form reveal evolutionary conservation despite diversification of life form within Adenia.
为了了解与生态和生命形式多样性相关的解剖多样性的进化模式和过程,利用明确的系统发育背景分析了腺属(Passifloraceae)的储存根和茎的解剖结构。对该属58个种的47个定量和定性性状进行了65000多次测定。枝状祖先的痕迹在整个类群中是明显的,因为小树枝和枝状类群都有相对短的,通常宽的,具有简单的,横向穿孔板的导管元件,和交替的侧壁凹点;纤维状血管元件,与血管相关的管胞,以及作为附加管胞元件的libriform纤维;轴向薄壁组织发育良好。观察到多种形成层变异,包括异常薄壁增生,异常维管束,连续的形成层和一种新型的木质部内韧皮部。某些分支的连续形成层、毛状体、皮肤特征和木质部是突触性的,而大多数特征是同塑的。腺腺瘤的几个解剖特征与旱胚性一致。角质化的、光合作用的成熟茎、狭窄的导管成分、高度聚集的血管以及其他表明干性的特征的反复丧失和获得表明了生态上重要的解剖特征的不稳定进化,而藤本植物生命形式的特征表明,尽管腺属生物形式多样化,但进化守恒。

The methods that Dr. Richard K. Benjamin used to isolate Zygomycetes are discussed. These processes involved the following five steps: (1) collection, (2) plating, (3) isolation, (4) culture, and (5) maintenance. Additional methods, materials and modifications used to isolate Zygomycetes are summarized. The author considers the flattening of the aerial hyphae onto the substrate of the faster- and higher-growing Mucorales for several consecutive days to be the critical step in isolating species of Coemansia, Piptocephalis, Syncephalis, and Dimargaritales. The methods used by other scholars to isolate, culture, and study many taxa in Zygomycetes also are discussed.
本文讨论了Richard K. Benjamin博士分离接合菌的方法。这些过程包括以下五个步骤:(1)收集,(2)电镀,(3)分离,(4)培养和(5)维护。总结了用于分离接合菌的其他方法、材料和修饰。作者认为,连续数天将空中菌丝压扁在生长速度更快和更高的毛霉菌的基质上,是分离Coemansia、Piptocephalis、Syncephalis和Dimargaritales的关键步骤。其他学者对接合菌中许多分类群的分离、培养和研究方法也进行了讨论。

Two new species of Prolixandromyces (Laboulbeniales) parasitic on Rhagovelia (Heteroptera: Veliidae) are described and illustrated: Prolixandromyces benjaminii from the Philippine Islands and P. lanceolatus from Africa (Madagascar, Malawi, Nigeria, Sierra Leone, and South Africa) and Asia (Indonesia: Sulawesi, Sumba, Timor; Malaysia: Selangor; and Sri Lanka). In order to accommodate these species the circumscription of Prolixandromyces is emended. The new taxa are compared with the one known species from the Old World, P. triandrus from Spain, and with the five known New World taxa.
描述并说明了寄生于横毛蝇上的两个新种:来自菲律宾群岛的benjaminiprolixandromyces和来自非洲(马达加斯加、马拉维、尼日利亚、塞拉利昂和南非)和亚洲(印度尼西亚:苏拉威西岛、松巴岛、东帝汶)的P. lanceolatus;马来西亚雪兰莪州;和斯里兰卡)。为了适应这些物种,修订了多雄菌科的范围。将新分类群与来自旧大陆的一种已知物种——西班牙的triandrus,以及五个已知的新世界分类群进行了比较。
