The paper presents environmental conditions and morphological characteristics of pyramidal fir (Abies alba var. pyramidalis) in the locality of Ogorijevac in southwestern Serbia. Pyramidal fir trees grow in three localities in Europe, but only as individual trees. A site of pyramidal fir (Abies alba var. pyramidalis) in the locality of Ogorijevac near the town of Sjenica in Serbia was first studied by Tosic in 1963, who described some characteristics of the locality in which the pyramidal fir occurs and some morphological characteristics of the trees. This paper provides a detailed description of the parent rock, soil, climate characteristics of the locality and morphological characteristics of the trees.

AbstractWater frog mating calls from two localities were studied and analyzed. Recordings were made in the summer of 2010 at the Arkutino swamp near the town of Primorsko and at the Vurbitza River near the town of Momchilgrad. A total of 154 calls were analyzed and the results suggested the presence of both the Marsh frog (Pelophylax ridibundus) and the Levant frog (Pelophylax bedriagae) in both sites, with the former being more frequent in Vurbitza River, and the latter – in Arkutino. At Vurbitza, we also captured and measured 2 specimens, which morphological characteristics differed from P. ridibundus and matched those of P. bedriagae. These are the first localities for P. bedriagae in Bulgaria.

A New Species

ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

Key Issues

The coffee growth is considered to depend, partly, on the environmental condition at which they develop to accomplish both vegetative and generative stages. An exploratory survey in Lampung aimed at investigating the morphological characteristics of 13 Robusta coffee accessions growing on different altitudes.Local superior coffee clones were selected from eight farms, and subjected to identifications. Three key issues were concerned for both quantitatively, i.e. plant components of leaves, branches, and fruits, and qualitatively such as leaves and fruit characteristics, i.e. colour and shape. The analysis shows a similarity of about 60% of total qualitative variable identified among different accessions. The remaining characters are suggested to be more varying such as flush colour, leaf surface, ripe fruit colour, and stipule shape. Furthermore, a quantitative analysis showed a higher level of similarity for fruit characters, i.e. fruit length, -width, and -thickness, and to a slightly lower level for leaf characteristics, i.e. leaf length and -width, and number of productive branches. It was revealed that some variables, i.e. fruit weight; leaf and seed; and canopy characteristics, explaining the morphological variation of coffee throughout the accessions. Furthermore, cluster analysis may indicated a possible similarity of coffee morphologies either from area with different or the same environmental conditions. A high heterogeneity related to environmental conditions, genotypic variations, plant nutritional status, and agronomic practices, which unable to confirm in the present study, may limit the specific conclusions.

The objectives of this work were to evaluate the frequency of polyembryony, and to identify zygotic and nucellar seedlings of Citrus volkameriana using RAPD. Twenty-five polyembryonic and eight monoembryonic seeds were cultivated in vitrofor six months. DNA from seedlings was extracted and used in combination with five RAPD primers to identify zygotic or nucellar origin of the seedlings. Environmental conditions of the year affected significantly (P<0.05) the morphological characteristics of fruitsand the number ofembryos per seed. Polyembryonic seeds ranged from 30.9%, 44.8% to 54.4% over three years. Morphological characteristic was not correlated with polyembryony. In vitro culture enable all embryos of each seed to grow, favoring the percentage of seedlings identified as zygotic. In polyembryonic and monoembryonic seeds, 25.9% and 87.5% of the seedlings, respectively, were sexually originated. In polyembryonic seeds, not all zygotic seedlings were produced by small embryos located at the micropyle.

Abstract Dinoflagellates in the genus Gambierdiscus are known to produce potent neurotoxins known as ciguatoxins. These toxins vector through the food web and can reach sufficiently high levels to cause ciguatera fish poisoning (CFP). In many regions of the Caribbean, little is known about the occurrence of CFP-causing species or the incidence of CFP, despite its apparent regional increase over the last few decades. Given the intraspecific variability in content and potencies of these toxins among Gambierdiscus species, the precise identification of local species of this genus is crucial. In this study we confirm the presence of the epibenthic dinoflagellate Gambierdiscus caribaeus in the Colombian continental Caribbean. Cells were collected in seagrass beds of Thalassia testudinum in Bonito Gordo, a site located on the western side of Bahía Concha, Tayrona National Natural Park, near the city of Santa Marta, Colombia. Subsequently, a single strain of Gambierdiscus could be established for further identification. Morphological (light and scanning electron microscopy), and molecular results (partial LSU and ITS rDNA sequencing) were consistent with the original description of G. caribaeus, as well as with the morphological characteristics shown by other authors in organisms obtained near the sampling area.

In Turkish geographical nomenclature certain ‘round’ numbers are regularly employed in an arbitrary sense. Most important of these are ‘a thousand and one’ (bin bir), used to express the idea of ‘countless,’ and ‘forty’ (kirk), which is similarly used for ‘numerous.’ As examples of the first may be cited the well-known ‘thousand-and-one-column’ (Bin Bir Direk) cistern at Constantinople and the ‘Thousand and one Churches’ (Bin Bir Kilisse) in Lycaonia. For the second we may instance several rivers called Kirk Getchid (‘Forty Fords’, in Greek Sarandáporos), the town Kirk Agatch (‘Forty Trees’), springs called Kirk Gueuz (‘Forty Eyes’), districts called Kirk In, Kirk Er (‘Forty Caves’) and numerous others.Side by side with names like the foregoing, which explain themselves if we read ‘numerous’ for ‘forty,’ we find certain localities denominated simply ‘the Forty’ (Tk. Kirklar, Gr. Saránda). They are especially common in Pontus but occur also elsewhere, as e.g. in Mysia, where there are at least two villages called Kirklar, and in Caria, where the name is applied to a site with ruins of a church near the ancient Loryma and to an ancient tomb east of Knidos. Similarly mysterious are names like Kirklar Dagh (‘Mountain of the Forty,’ not ‘Forty Mountains’) which like the foregoing, imply an association with forty persons. These ‘forties’ call for explanation.

AbstractThe aim of this study was to evaluate the traffic-related effects on morphological and anatomical traits of Fraxinus rotundifolia and Morus alba along the Malayer-Hamedan road. In the study area, populations of two species of F. rotundifolia (30 individual trees) and M. alba (30 individual trees) were selected for sampling. The results showed that the leaf and stomata dimensions at distances near to the roadside were significantly lower compared to longer distances from the road. For F. rotundifolia, the number of veins showed the lowest plasticity, while in case of M. alba, the stomata length (P = 0.52) and the number of veins (P = 0.54) showed the lowest plasticity related to the environmental conditions. Results of discriminant analysis for population grouping for the two species of F. rotundifolia and M. alba confirmed the accuracy of grouping 74.8% and 79.5%, respectively. In case of trees that were farther away from the road, guard and epidermal cells were located at the same level. We found that the leaf stomata in M. alba were closed more than in F. rotundifolia at the same distance. Totally, the results of this research show that the air pollution stress impacted the tree morphological traits. From the two species, F. rotundifolia was more resistant in terms of pollution stress.

AbstractSymptoms of anthropogenic changes in the vascular plant flora include the spread of some species groups and the extinction of others. Also habitat condition changes (eutrophication, pollution etc.) and biodiversity loss (at a regional, national and even continental scale) should be mentioned. Numerous papers with rare plant species localities and endangered habitats have been published but the extinction processes and scale of this phenomenon in urban areas where environmental conservation is crucial, are not often analysed. The aim of the present study is to estimate species loss in the vascular plant flora of the town Strzelce Opolskie (Chełm, Silesian Upland) on the basis of the floristic literature and botanical surveys carried out from 2011 to 2013. A comparison has been made between the list of species reported up to 1945 and those species currently occurring in the study area. As a result, a list of 99 species included in the red list of plants of Opole and Silesian voivodeships is presented. Among this group, 45 species are not confirmed after 1945. Numerous extinct and endangered species are from families: Orchidaceae (8 species), Cyperaceae (7 species), Ranunculaceae (7 species) and Lamiaceae (6 species). Strongly represented are species associated with the communities of Festuco-Brometea and Querco- Fagetea classes. From the species presented, 18 species are included in "Red List of Vascular Plants of Poland" (MIREK ET AL. 2006). It was found that the extinct species represent about 7% of Strzelce Opolskie vascular plant flora. It is a focus point for local authorities to protect botanically valuable areas. Actually, the only Miejski Park is under the conservator's protection and there are few individual trees protected due to their age or size.
