Abstract Cypselar morphology of 24 taxa including 16 species and eight subspecies of the 29 Turkish Carduus L. (Asteraceae) taxa (belonging to 17 species) were examined by stereomicroscope and scanning electron microscope. In this study, nine qualitative characters (cypselar shape, symmetry, kurtosis, surface ornamentation and different features of cypselar surface cells) and five quantitative characters (cypselar length and width, umbo length and width, ring diameter) were examined. Macromorphological studies revealed oblanceolate, narrowly obovate, narrowly oblong to oblong cypselar shapes with striate or furrowed surface. Based on scanning electron microscopic investigation of cypselar surface, the studied taxa were divided into five main types: scalariform, scalariform-ribbed, scrobiculate-ribbed, scrobiculate and scrobiculate-foveolate. An identification key of studied species based on cypselar morphology has been provided. The results indicate that cypselar features can be used as diagnostic taxonomic characters in examined Carduus species.

Abstract This study presents an updated syntaxonomic review of the annual psammophilous plant communities from coastal dunes and inland territories of Sicily. A total of 301 relevés were collected. The relevés data were analysed using classification (WPGMA, similarity ratio) and ordination methods (detrended correspondence analysis and principal component analysis). Eighteen plant communities were recognized, four of which are described here for the first time (Rostrario littoreae-Tuberarietum villosissimae, Filigini asterisciflorae-Loeflingietum hispanicae, Astragalo kamarinensis-Coronilletum repandae, Sileno coloratae-Ononidetum variegatae cutandietosum maritimae). The surveyed associations are ascribed to the following orders: Cutandietalia maritimae (annual associations of semi-fixed dunes) and Malcolmietalia (inland sandy soil communities). Moreover, for this latter order, a new alliance, Filagini asterisciflorae-Linarion humilis, that groups the therophytic communities from fossil dunes and deep sandy soils of the inland of the Sicily, is proposed. Another aim of this study is to check and compare the discrete model of plant community against the continuum model along environmental gradients.

Abstract There is an increasing need for data on the patterns of population changes for rare species at the regional, national and European scales in the context of the Natura 2000 reporting on the state of species’ conservation. This reporting requires the use of the same protocol over a whole region or country with the major constraint that it has to be shared by a large array of conservations and monitoring structures. The protocol has therefore to be both precise and reproducible but also simple enough to be used over a large number of sites and years, and has moreover to be accepted by various conservation structures. In this aim, the Alps-Ain flora conservation network (Réseau Alpes-Ain de Conservation de la Flore), a network composed of flora conservation stakeholders for 2 regions, Provence-Alpes-Côte d’Azur and Rhône-Alpes, set up a series of nested protocols to monitor populations at different spatial scales (levels). Each monitoring level is set up to answer to a specific aim and corresponds to a protocol shared by all the network actors. The first level, detailed below, is defined for the regional scale (“territory” level) with the site as observation unit. The second level aims at identifying if in a specific site (“station”) a population is stable, expanding or regressing and if natural or anthropic factors can explain this dynamics. The observation unit is a plot or a transect and the variables measured are frequencies or numbers and environmental parameters. The third level is an individual-based survey (“individu”) and aims at understanding the demographic processes affecting a population. The observation unit is here the individual plant. The link between the 3 levels is described in Figure 1. The “territory” level protocol was developed over several years of discussions and in situ tests on several species (Table 1). Its aim is to identify increases or decreases of species’ size at the scale of the region. The variables used for this monitoring are simple and easily reproducible: area of presence and frequency. During the process, we realized that even a simple protocol could not be applied to a large range of species. We therefore propose some variations on a common methodological base, depending on the biology of the species (longevity, clonality, dormancy, size of individuals…). An originality of the protocol is to note the non-detection of the species in a given point at a given time to be able to document the expansion or the regression of the species in the site. A first step therefore consists in defining the zone in which the species will be looked for, the prospection zone (ZP). This zone should correspond as much as possible to the potential habitat of the species and has to remain constant over time. Within this zone, the area of presence (AP) is determined using the envelope formed by the GPS points where the species is found. Population size is then estimated as the frequency of occurrence by contact-points along a
摘要:在Natura 2000报告物种保护状况的背景下,对区域、国家和欧洲范围内珍稀物种种群变化模式的数据需求日益增加。这种报告要求在整个区域或国家使用相同的议定书,其主要限制是必须由大量的保护和监测结构共享。因此,该协议必须既精确又可复制,同时又足够简单,以便在大量地点和年份中使用,而且还必须为各种保护结构所接受。为此,由两个地区(Provence-Alpes-Côte d’azur和Rhône-Alpes)的植物保护利益相关者组成的阿尔卑斯-艾因植物保护网络(r<s:1> seau Alpes-Ain de conservation de la Flore)建立了一系列嵌套协议,以监测不同空间尺度(水平)的种群。每个监控级别的设置都是为了满足特定的目标,并对应于所有网络参与者共享的协议。下面详细介绍的第一级是区域尺度(“领土”级),以场地为观察单位。第二级的目的是确定在某一特定地点(“站”)的人口是稳定的、扩大的还是倒退的,以及自然因素或人为因素是否可以解释这种动态。观测单位是一个图或样带,测量的变量是频率或数字和环境参数。第三个层次是基于个人的调查(“个人”),目的是了解影响人口的人口进程。观察单元在这里,单株。图1描述了这3个级别之间的联系。"领土"级议定书是经过几年的讨论和对若干物种的实地试验而制定的(表1)。其目的是确定该区域尺度上物种大小的增减情况。用于此监视的变量简单且易于再现:存在区域和频率。在这个过程中,我们意识到,即使是一个简单的协议也不能适用于大范围的物种。因此,我们根据物种的生物学特性(寿命、克隆性、休眠、个体大小等),在共同的方法基础上提出了一些变化。该议定书的一个独创性之处在于注意到在特定时间的特定地点未发现物种,以便能够记录该地点物种的扩展或消退。因此,第一步是确定寻找物种的区域,即勘探区(ZP)。这个区域应该尽可能与该物种的潜在栖息地相对应,并且必须随着时间的推移保持不变。在这个区域内,存在区域(AP)是用发现物种的GPS点形成的包络来确定的。然后,根据至少两个样带上的接触点来估计种群大小,以考虑到该地点的环境异质性(见图1)。对于种群大小和分布变化很大的物种,样带应代表AP;对于种群非常稳定的物种,我们建议设置固定样带,以减少年际和空间变化,但管理者可以自由选择样带的位置。每个样带至少取100个点,以便对发生频率有一个可靠的估计。对于地表覆盖度低的物种,我们建议用接触面积代替接触点,即沿样带放置与接触点相似的小地块。情节的区域必须提前确定,不应该随着时间的推移而改变。目的是避免极端的频率值(接近0或1),以便能够检测到种群规模的增加或减少。每个勘探区对应一个数据点。在区域尺度上,人口由zp的集合表示。为了对种群规模及其动态有一个很好的估计,ZPs应该对应于所有现有站点的随机或分层样本。然而,这是困难的,在实践中,调查的zp是生物体可以承诺的。然后,RAACF必须确保zp的样本能够代表物种的分布。调查的频率取决于该物种的生物学特性。对于多年生物种,我们建议在没有灾难性事件的情况下,时间步长为3至5年。对于一年生或休眠物种,为了获得可靠的AP和大小估计,并消除年际(正常)波动,应连续3-5年进行调查,然后在3-5年后重复进行调查。为了保证数据的聚合,网络开发了一个web服务数据库。 该方法是对欧盟生境指令(理事会指令92/43/EEC)框架内植物种群评估要求的实际回答。

Abstract Omphalodes kuzinskyanae Willk. is an endangered annual plant of the family Boraginaceae, endemic to a narrow coastal area in the Lisbon region (Portugal). Omphalodes littoralis Lehm. occurs in northwest Spain (subsp. gallaecica) and northwest France (subsp. littoralis). Three approaches were used to assess the ecological requirements of O. kuzinskyanae: (1) physical and chemical characterization of their habitat soil; (2) phytosociological analysis; (3) comparison of several life history parameters under different light conditions. Germination experiments were conducted to evaluate seed dormancy. The results show that O. kuzinskyanae occurs in thin sandy soil with a substantial amount of organic matter and clay, mostly over limestone pavements. Phytosociological analysis shows that O. kuzinskyanae occurs both in sciophytic and heliophytic communities. Life history comparisons demonstrated that this plant has a strong preference for sciophytic conditions: under strong shade, plants have a higher survival rate, attain a greater height and width, and produce approximately nine times more seeds than in sunny conditions. In contrast with O. kuzinskyanae, published data on O. littoralis indicate that this species occurs in heliophytic conditions. This group of Omphalodes is possibly limited both in geographical distribution and habitat by its vulnerability to hydric stress. Scenarios are discussed that can explain the extensive gap separating the present ranges of the two species and their ecological differences. We propose two new syntaxa: Linario arenariae-Omphalodetum littoralis, Geranio purpurei-Galietum minutuli omphalodetosum kuzinskyanae.

Abstract This study assessed the combined effect of the size and shape of inventory plots on the analysis of the density and diameter structure of saplings and juvenile trees. Thirty square plots of 400 m² were randomly laid out and each one was divided into 400 quadrats of 1 m². Stem number of recruits was recorded for all tree species and their diameter at breast height was measured in the quadrats. Seven types of subplots with different shapes and sizes were considered by grouping adjacent quadrats of 1 m². The Green index was used to assess the spatial distribution of regeneration and Weibull distribution was applied to model stem diameter distributions. Box–Cox transformations and weighted regression were used to model the relationship between the Green index, the plot patterns and the standard error of the estimation of the regeneration density. The same analyses were applied to model the relationship between the Green index, the plot patterns and the mean absolute error of the shape parameter of the Weibull distribution. The Green index and the plot size had a significant impact on the error of the regeneration density estimation. For clumped distribution of individuals, the plot shape had a significant impact on the error of their density estimation. As for stem diameter distribution, only the plot size had a significant effect on the mean absolute error of the stem diameter structure. The rectangular plots and square plots of 100 m² (14 m × 7 m and 10 m × 10 m) appeared more suitable for an effective structural analysis of woody species regeneration in the tropical dense forest for an aggregated distribution and a random distribution, respectively.
摘要本研究评价了调查样地的大小和形状对幼树和幼树密度和直径结构分析的综合影响。随机布置30个400 m²的方形地块,每个地块分为400个1 m²的样方。在样方中记录了所有树种的新枝茎数,并测量了其胸高直径。通过对相邻1 m²的样方进行分组,考虑了7种不同形状和大小的子样地。采用格林指数评价再生空间分布,采用威布尔分布模拟茎径分布。利用Box-Cox变换和加权回归对格林指数、样地模式和再生密度估计标准误差之间的关系进行建模。用同样的分析方法对格林指数、图型和威布尔分布形状参数的平均绝对误差之间的关系进行了建模。格林指数和样地大小对再生密度估计误差有显著影响。对于聚集分布的个体,样地形状对其密度估计误差有显著影响。茎径分布方面,只有样地大小对茎径结构的平均绝对误差有显著影响。100 m²矩形样地(14 m × 7 m)和10 m × 10 m方形样地(10 m × 10 m)分别表现为聚集分布和随机分布,更适合于热带密林木本物种更新的有效结构分析。

Stem number of recruits was recorded for all tree species and their diameter at breast height was measured in the quadrats. Seven types of subplots with different shapes and sizes were considered by grouping adjacent quadrats of 1 m².

Abstract New records for the flora of Tunisia and, in part, for North Africa of taxa of Orobanche sect. Orobanche subsect. Minores (Beck) Teryokhin, are reported. These records come from field research carried out between 2010 and 2014 in the Kroumiria region in northwestern Tunisia and herbarium studies. Infraspecific taxa and chorological data about the identified taxa (Orobanche amethystea Thuill., Orobanche canescens C. Presl, Orobanche hederae Duby, Orobanche litorea Guss., Orobanche minor Sm. and Orobanche pubescens d’Urv.) are reported. Literature data on host and distribution are also revised. Orobanche litorea is new to North Africa, and O. canescens has been confirmed for North Africa more than 100 years after the only known collection. Orobanche hederae and O. pubescens are new to Tunisia.

Abstract A study was carried out in two phytodistricts (Ouémé-valley and Plateau) to assess the population structure of two bamboo species (Oxytenanthera abyssinica (A. Rich.) Munro and Bambusa vulgaris Schrad. ex J.C. Wendl. in two topographical units: plateau and wetlands. In each phytodistrict, bamboo stands were randomly selected in each topographical unit for inventory using a 0.25-ha square plot. Structural parameters of bamboos were computed and compared using a Wilcoxon rank test. Spatial distribution of the two bamboos was also assessed using the method of neighbourhood density in relation to a focal point. The observed culm diameter distribution was established for each stand and adjusted to the two-parameter Weibull distribution. Oxytenanthera abyssinica showed the highest culm and clump density values in both wetlands and plateau whereas B. vulgaris showed greater values of mean diameter and dominant height whatever the habitat. Diameter structures of bamboo stands showed a right asymmetric distribution and bamboo spatial distribution was highly aggregative, especially in wetlands. No significant difference in mean relative neighbourhood density between species was noted. However, a significant difference was observed between wetlands and plateau (p < 0.001) indicating strong influence of the topographical units on the relative neighbourhood density of bamboo species. All of these findings are determinants in designing suitable management strategies for bamboo populations in Benin, particularly with the increasing demand to build fish-traps and shelter in the traditional fishing systems “Acadja”.

Abstract The water relations of showy laminar floral tissues (petals and tepals) were studied in 20 Mediterranean plants successively blossoming under ambient conditions. The water potential and osmotic potential of floral tissues decline according to the succession of the median day of flowering of the selected plant species. The highest (least negative) value of floral water potential (–0.32 MPa), among the examined species, was measured in petals of Anemone coronaria in March, and the lowest value (–1.25 MPa) in petals of Coridothymus capitatus in June. Low values of water potential of floral tissues coincided with constraints in declining values of osmotic potential at the onset of the dry period in the Mediterranean region; this apparently resulted in a reduction of turgor of floral tissues of Mediterranean plants subjected to water shortage. The reduced osmotic potential was correlated with enhanced soluble sugar content of floral tissues, presumably contributing to the expansion and water status of flowers under water scarcity, by decreasing water requirements.

Abstract The Prodrome of French vegetation is presented from its beginning in 1996 to the publication in 2004 of the first version of the national synsystem detailed up to the level of suballiance (PVF1). Work began in 2006 to produce a second edition, called PVF2, which aims to describe 78 of the 80 classes recorded in mainland France and Corsica, up to the level of association and subassociation. So far, 19 classes have been published, five classes are ready for publication and 54 classes are under preparation. The most important classes of PVF2, especially forest classes, should be completed in 2015.
