Résumé :

Recent field and herbarium studies of the southern African genus Ursinia (Anthemideae, Asteraceae) in Namaqualand, South Africa, have revealed greater morphological variability than currently accommodated and a high percentage of misidentified specimens. In an attempt to remedy this we herein describe four new species (Ursinia arida, U. glandulosa, U. kamiesbergensis and U. laciniata) and provide a key to the species in the region, together with illustrations of their involucral bracts and paleae. The species can be distinguished by a combination of their life history, vestiture, presence or absence of appendages on the paleae, and shape of the involucral bracts and their scarious apices.

Résumé :

The aim of this study was to investigate the effect of temperature and sowing date on the phenology of Ursinia cakilefolia, a Namaqualand ephemeral species. Seeds were sown on different dates and plants were subjected to various temperature treatments. Sowing date had a distinct effect on the growth and phenology of the plants. From the results it seems that temperature plays an important role in the timing of phenological stages. However, the effect of temperature differed between sowing dates. The plant's response to temperature is apparently modified by the prevailing photoperiod, although it may also be due to an endogenous rhythm. Generally it seems as if plants require cold temperatures from sowing until the initiation of flower buds, after which the plants need heat for anthesis and further development.

Résumé :

Abstract The current conservation status of the rare vascular plant species and rare forest communities of the Volyn Upland (Ukraine) was characterized and analyzed. We found 14 rare plant species belonging to the Red Data Book of Ukraine in this territory (Lycopodium annotium L., Allium ursinum L., Cephalanthera longifolia (L.) Fritsch, Cephalanthera rubra (L.) Rich., Cypripedium calceolus L., Epipactis atrorubens (Hoffm.) Schult., E. helleborine (L.) Crantz, Lilium martagon L., Listera ovata (L.) R. Br., Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich., P. chlorantha (Cust.) Reichenb., Galanthus nivalis L., Carex umbrosa Host) and 28 locally rare species preserved within the Volyn, Rivne and Lviv regions. The major threats for these species were indicated. Four rare associations, according to the Green Data Book of Ukraine, were studied in the Volyn Upland (Carpineto (betuli)–Quercetum (roboris) hederosum (helicis), Carpineto (betuli)–Fraxineto (excelsioris)–Quercetum (roboris) alliosum (ursini), Tilieto (cordatae)–Carpineto (betuli)–Quercetum (roboris) alliosum (ursini) and Pinetum (sylvestris) caricosum (humilis)) and their structure, main features and status were characterized in detail. The importance of further research, and the development of recommendations for the conservation and continued preservation of these forest ecosystems of the Volyn Upland was highlighted.

Résumé :

AbstractThe taxonomic level and phylogenetic relationship of the Moldavian steppe viper was investigated using blood serum electrophoresis, immunological comparisons of blood serum albumin and morphological comparisons. The traditional hypothesis that the Moldavian steppe viper is a secondary intergradation between Vipera (ursinii) renardi and V. ursinii rakosiensis could not be verified. Although morphologically similar (but not identical) to these two taxa, it has a closer immunological distance to the Balkan mountain subspecies, V. u. macrops and V. u. graeca. Specific antisera against serum albumins of V. u. graeca, V. u. ursinii (wettsteini) and V. u. eriwanensis were available, and the three vipers to be tested: rakosiensis, renardi and the Moldavian steppe viper branch off from different stems: rakosiensis seems close to ursinii, V. (u.) renardi appears fairly close to eriwanensis, both of which share a common stem with the rakosiensis-ursinii lineage. The Moldavian steppe viper shows high distance to both ursinii and eriwanensis, but low distance to graeca. The electrophoretic pattern show great differences from all other geographic forms tested (seven). We conclude that the Moldavian steppe viper represents a separate subspecies: Vipera ursinii moldavica ssp.n.

L’etude de la répartition et de la morphologie comparée de Vipera ursinii en Roumanie apporte les résultats suivants: 1. Les populations de Fînatele Clujului, maintenant disparues, appartenaient à la sous-espèce V. ursinii rakosiensis. 2. Les populations de Moldavie, qui présentent un mélange de caractères de V. ursinii rakosiensis et de V. ursinii renardi, correspondent à une zone d’intergradation secondaire. 3. Les populations du delta du Danube, également plus ou moins intermédiaires entre ces deux sous-especès, présentent en outre quelques caractères particuliers. En attendant de nouvelles recherches, il paraît cependant plus sage de leur conserver leur statut actuel de V. u. renardi.

Résumé :

Este artigo traz o debate dos corpos para analisar subjetivações ursinas. Inicialmente, é delineada uma breve revisão conceitual de analíticas de poder que contribuem para os estudos em embodiments, com destaque para Laclau e Mouffe (1987), Butler (2010) e Michel Foucault (1996). Foi realizada uma pesquisa qualitativa e corpus de pesquisa foi produzido por meio de entrevistas individuais semiestruturadas com 19 participantes. Os dados foram analisados sob a ótica pós-estruturalista do discurso tendo em vista as abordagens laclauniana e foucaultiana. A pesquisa conclui que o discurso ursino sobredetermina práticas dispersas no campo de afetividades analisado ao articular um esquema corpóreo "masculino". Este esquema se assume como um ponto nodal e, consequentemente, é o primeiro a ser acionado nas subjetivações dos participantes. Porém, tal processo não se concretiza de forma plena, nem elimina particularidades que muitas vezes parodiam demandas comportamentais.

Texte intégral

Résumé :

The karst viper (Vipera ursinii ssp.) favours high-mountain dry grasslands in southern and south-eastern Croatia. It is medically less important than other Vipera species, because of its remote habitat and the very small amount of venom that it injects by its relatively short fangs. The scientific literature on Vipera ursinii deals mostly with the morphology, ecology and distribution range of this snake, due to the species’ conservation issues, while the toxinological aspects of its venom have not so far been investigated. Here we report on the composition and biological activity of the Vipera ursinii ssp. venom. Using a proteomics approach, we have identified 25 proteins in the venom that belong to seven protein families: snake venom metalloproteinase, serine protease, secreted phospholipase A2, cysteine-rich secretory protein, snake C-type lectin-like protein, serine protease inhibitor and nerve growth factor. The Vipera ursinii ssp. venom was found to be distinctively insecticidal. Its lethal toxicity towards crickets was more than five times greater than that of Vipera ammodytes ammodytes venom, while the opposite held in mice. Interestingly, the mode of dying after injecting a mouse with Vipera ursinii ssp. venom may suggest the presence of a neurotoxic component. Neurotoxic effects of European vipers have so far been ascribed exclusively to ammodytoxins and ammodytoxin-like basic secreted phospholipases A2. Structural and immunological analyses of the Vipera ursinii ssp. venom, however, confirmed that ammodytoxin-like proteins are not present in this venom.

Résumé :

ABSTRACT. There is considered a layered heterogeneous poroelastic isotropic medium with physical parameters characterized by piecewise constant functions of the depth only. We derive a mathematical algorithm for calculating reflected/transmitted poroelastic waves across all temporal frequencies. To define the frequency effect we use the dynamic permeability expression proposed by Jonhson, Koplik and Dashen; in the time domain, this coefficient introduces order 1/2 shifted fractional time derivative involving a convolution product. The algorithm proposed is based on the formalism introduced by Ursin. The algorithm is tested numerically in a 1D-case. The numerical experiments confirm the effectiveness of the proposed algorithm in identifying the main wave events in both low frequency and high frequency regimes in the reservoir and laboratory scales.Keywords: stratified porous medium, Biot and Biot-JKD models, Ursin’s Formalism.RESUMO.

Résumé :

The skulls of the wombats, Lasiorhinus latifrons and Vombatus ursinus, were measured in order to compare the craniofacial morphology, including sexual dimorphism, in these two species. The skulls of V. ursinus tend to be bigger than that of L. latifrons. In both species measurements of males are greater than those of females. The difference between maxillary and mandibular inter-molar breadth was greater, and the skull length/zygomatic arch breadth ratio was smaller, in V. ursinus than in L. latifrons. It is proposed that the masseter muscles of V. ursinus are better developed than those of L. latifrons, and that the interspecific difference in skull form is influenced by environmental factors and diet.

Résumé :

Abstract The study investigates the genetic differentiation among two subspecies of Allium ursinum L., namely A. ursinum subsp. ursinum and subsp. ucrainicum as well as their putative hybrid that is represented by individuals with intermediate morphology. Inter-Simple Sequence Repeats (ISSR) were applied to determine the status of intermediate morphotypes in terms of their genetic pattern and to assess the level of genetic variability within and between various populations of A. ursinum. The study comprises 144 specimens from nine populations along the east-west transect in Poland, which includes localities of both subspecies and their putative hybrid. Among the examined populations, 48 bands were amplified, of which 45 were found to be polymorphic. The principal coordinate analysis (PCoA), the neighbour-net analysis and Mantel test showed a strong correlation between genetic variability and geographic distance. Analysis of molecular variance (AMOVA) revealed that a greater proportion of total genetic variation resided within populations rather than among them. The Structure Bayesian clustering analysis revealed the presence of three distinct genetic groups within studied populations, where ‘eastern’ genotypes correspond to A. ursinum subsp. ucrainicum, and ‘western’ to subsp. ursinum; whereas the third genetic group has the largest share in the individuals occurring at the border of the distribution ranges of both subspecies. The emergence of the third genetic group is probably an effect of hybridization events occurring within the secondary contact zone. Typical morphologically intermediate populations occur only in a relatively narrow geographical zone, but the hybrid zone revealed by molecular markers is actually much wider than it is suggested by the morphological pattern of individuals. The current distribution pattern of both subspecies of A. ursinum and their hybrid zone is related to the two main directions of postglacial migration of Fagus sylvatica to the area of Poland. The hybrid zone arose as an effect of the secondary contact of two divergent lineages of A. ursinum.

Résumé :

O “Cuidando do Ursinho” é um projeto de extensão universitária interdisciplinar criado em 2016, que iniciou seu trabalho realizando atividades educativas com crianças envolvendo uma “consulta” clínica de um bichinho de pelúcia. Com a observação dos resultados positivos obtidos nessas experiências e com a análise da necessidade de criação de metodologias de educação em saúde para o ambiente escolar, foi criado um jogo de tabuleiro chamado “Liga da Saúde”, trabalhado com crianças escolares de escolas públicas. Objetiva-se a desconstrução do medo do profissional de saúde; a construção de conhecimentos acerca do SUS e a integração entre aprendizado escolar e cuidado em saúde. Para isso, as crianças são convidadas a formarem uma equipe de saúde a fim de desvendar os mistérios da “Ursolândia”, uma cidade na qual muitos ursinhos estão ficando doentes. Para isso, cada um dos alunos ganha um passaporte (cartão SUS) para entrar no jogo e um “poder”, que representa uma das 4 funções dos profissionais da APS (médico, enfermeiro, agente de saúde e dentista). No decorrer da história, as crianças devem realizar missões que envolvem a discussão de diversos temas como dengue, reconhecimento da comunidade, partes do corpo, respeito às diferenças, meio ambiente, alimentação, saúde mental, vacinação, atividade física, gênero e saúde bucal. Foi possível perceber que os conhecimentos trabalhados foram aprendidos pelas crianças, como a função das agentes de saúde, o preparo de soro caseiro, o reconhecimento de mapas, a leitura de horas no relógio, entre outros. Ademais, valores como liderança e trabalho em equipe são incorporados, fazendo com que as crianças entendam que não precisam competir umas com as outras. Desse modo, há uma troca intensa de afeto e saberes entre estudantes e crianças, reinventando a arte do cuidar, na prática da saúde.

Résumé :

AbstractDuring a continuous population study of Vipera ursinii rakosiensis, 79 specimens were measured in the field, between 1993 and 1997. Body length and body mass of six juveniles were compared to those of 43 more specimens which were kept during their first winter in terraria. Significant differences were found in favour of the juveniles kept in captivity, whereas a comparison with earlier data from 1953 showed a strong decline in juvenile body mass. Based on body size, three age classes could be distinguished in the study population. The annual activity and reproductive cycle of the Hungarian meadow viper is described for the first time. A comparison to other European populations of Orsini′s viper revealed a remarkably higher clutch size in Vipera ursinii rakosiensis, which is explained by the larger body size of females in the particular population.

Résumé :

Production of functional food with significant antioxidant and anti-carcinogen activity is considered to be extremely significant in conditions of global ecological crisis. Among Allium species, wild garlic (Allium ursinum L.) along with the ordinary garlic are known to be the leaders in accumulation of natural antioxidants and sulfur-containing compounds with strong anti-carcinogen activity. Taking into consideration that Allium species belong to a group of natural accumulators of selenium, foliar biofortification of wild garlic with sodium selenate was achieved in Gudermes region of the Chechen republic. It was demonstrated that fortification of plants with selenium resulted in significant increase of chlorophyll a and b as well as carotene content, and two-fold increase of both polyphenol concentration and total antioxidant activity. Total dose of 2 mg Na2Se04 per square meter provided 14.4-fold increase of selenium content in A. ursinum leaves. Biofortification of plants with selenium resulted in 1.36, 1.28 and 1.38-fold increase of Cr, Fe and V concentration in leaves compared to leaves of non fortified plants. Leaves of A. ursinum fortified with selenium showed anomalously low Si content compared to non fortified plants. Compared to A. ursinum grown in Moscow region, wild garlic of the Chechen republic accumulated 2-fold lower levels of dry matter and 4.8-fold higher levels of monosaccharides. Compared to non fortified garlic leaves, those of A. ursinum demonstrated significantly higher levels of Cu, Fe, Mg и Zn. The results obtained suggest that A. ursinum fortified with selenium may be considered as a new functional food with strong antioxidant activity.

Résumé :

The aim of the present study was to evaluate Allium ursinum leaves and flowers extract anti-inflammatory effect. Plant extract 1:1 (w:v) was prepared from A. ursinum leaves by a modified Squibb repercolation method. The in vivo anti-inflammatory effects were evaluated on a rat turpentine oil-induced inflammation (i.m. 6 mL/kg BW). The animals were randomly assigned to nine groups (n=8): negative control, inflammation, A. ursinum flower extract (AUF), A. ursinum leaves extract (AUL), indomethacin (INDO) (20 mg/kg BW), aminoguanidine (AG) (50 mg/kg b.w./d i.p.) as a selective NOS2 inhibitor, NG-nitro L-arginine methyl ester (NAME) (5 mg/kg b.w./d i.p.) as a nonselective NOS inhibitor, L-arginine (ARG) (100 mg/kg b.w./d i.p.), NO synthesis substrate, and Trolox (20 mg/kg b.w./d i.p) as an antioxidant. At 24h from inflammation induction total oxidative status (TOS), oxidative stress index (OSI), nitric oxide (NOx) and in vitro phagocytosis test were reduced and the total antioxidative reactivity (TAR) was increased by the testes plant extracts. AUF had a better inhibitory effect than AUL. In conclusion, we provided evidence for the hypothesis that A. ursinum leaves and flowers extract exerts anti-inflammatory activity by inhibiting the phagocytosis through the reduction of the nitro-oxidative stress.

Résumé :

The superb flavor of trailing blackberry cultivars, such as `Marion', is derived from Rubus ursinus Cham. & Schlecht. Wild R. ursinus offer a range of horticulturally desirable traits to breeders, from high fruit quality to improved cold hardiness. Current cultivars are derived from relatively few sources of R. ursinus, selected primarily for fruiting characteristics. A replicated field trial of 460 clones, representing 20 populations from southern British Columbia, Washington, and Oregon, was established in 1994. Observations during the planting year have indicated that monitoring variability in the following reproductive traits will be useful in assessing diversity; budbreak, flowering, and fruiting date; lateral length; proportion of reproductive laterals; gender; flower and fruit number; and fruit size. In particular, there are clones that exhibit large fruit size (4 to 5 g), high flower number per lateral, and uniform fruit set. Analysis of these data will contribute to determination of relative genetic distances among the populations and enhance the understanding of the diversity available in R. ursinus.

Résumé :

Natural phenolics, which are ubiquitously distributed in plants, have been reported as functional factors in phytotherapy. We have examined phenolic compounds in the leaves and inflorescences of five significant medicinal plants of different plant families: Salvia officinalis (Lamiaceae); Achillea clypeolata (Asteraceae); Nymphaea alba (Nymphaeaceae); Rumex acetosella (Polygonaceae) and Allium ursinum (Alliaceae). The examined species were rich in total phenolics (up to 30.88 mg/g dry weight). According to their total phenolics contents, the plants can be arranged in the following order: A. clypeolata>N. alba>S. officinalis>R. acetosella>A. ursinum. Free phenolics prevailed in all species in comparison to the bound forms (63.72-82.68% of total phenolics). The highest content of total free phenolics was measured in the tissues of A. clypeolata and N. alba, and the lowest in A. ursinum. Five phenolic acids were isolated and measured. p-Coumaric and ferulic acids as derivatives of cinnamic acid prevailed in the leaves of R. acetosella and A. ursinum (up to 4.81%).

Résumé :

The experiment was conducted in the Botanical Garden of UMCS in Lublin. A collection of three ecotypes of Allium ursinum L. from Dukla, Roztocze Region and Bieszczady mountain range, were the subject of our study. The aim of the study was to compare the biometrical features and chemical composition of garlic leaves. There were substantial differences both in growth characteristics and flowering characteristics of the ecotypes of Allium ursinum. The Dukla ecotype formed the longest leaves, whereas the shortest ones were found in the Roztocze ecotype. The Bieszczady ecotype was characterized by the widest leaf blades, the longest leaf stalk and flowering stems as well as the largest diameter of inflorescence. The Roztocze ecotype had the largest number of flowers in an inflorescence, while the Dukla ecotype had the shortest flowering stems and the fewest flowers in an inflorescence. The largest concentration of dry mass in leaves was detected in A. ursinum from Roztocze. The largest concentration of proteins was detected in the leaves of A. ursinum from Bieszczady. The most flavonoids were assayed in the leaves of the Roztocze ecotype of A. ursinum, the fewest in the Dukla one. Phenolic acids were at their highest concentration in the leaves of bear's garlic from Dukla, while the lowest concentration was recorded in the leaves of the ecotype from Bieszczady. The garlic leaves from Dukla had also the highest content of essential oil, while the Roztocze ones had the lowest oil content. The ecotypes of Allium ursinum differed substantially when it comes to the number of components of their essential oils and the amount of selected components.

Résumé :

Evaluation of biochemical characteristics of 8 perennial Allium species is achieved (A. ramosum, A. caeruleum, A. erubescens, A. obliquum, A. moly, A. aflatunense, A. oreophilum and A.ursinum). High nutritional significance of separate decorative species is demonstrated. A. caeruleum is shown to be a leader in the accumulation of ascorbic acid (more than 9000 mg/100 g d.w.) and polyphenols (more than 8000 mg GAE/kg d.v.). Detected ascorbic acid concentration range for 8 studies Allium species was 568 (A. ramosum) – 9980 (A. caerulum) mg/100 g d.w.; polyphenols 1392 (A. obliquum) – 8582 (A. caerulum) mg GAE/kg d.w.; water-soluble compounds 28 (A. aflatunense, A. obliguum) – 69 (A. ramosum) mg/kg d.w.; chlorophyll 0.54 (A.oreophilum) – 1.69 (A. ursinum) mg/100 g d.w.; carotene 0.07 (A. oreophilum) – 0.25 (A.ursinum) mg/100 g d.w.; selenium 72 (A. ursinum) – 245 μg/kg d.w., (A. ramosum). Adequate consumption level of vitamin C may be provides by 6.2 g of A.caerulum leaves. Antioxidant activity of Allium species alcoholic extracts composed a range from 1.5 (A. obliquum) to 6.4 (A. ursinum) mg GAE/g d.w. A. ramosum and A. oreophilum demonstrated the highest content of total soluble solids. The highest content of photosynthetic pigments happened to be typical for A. ursinum. The ratio between antioxidant activity of alcoholic and water extracts of Allium leaves was in the range between 0.89 and 2.21 depending on plant species: the highest value was registered in leaves of A. ursinum, the lowest – in leaves of A. ramosum. In a whole the highest content of antioxidants was demonstrated for leaves of A. caerulum. The highest levels of photosynthetic pigments and antioxidant activity of alcoholic extracts were indicated in leaves of A. ursinum.

Résumé :

The chemical composition of fresh flowers from Allium ursinum (ramsons, bear's garlic, wild garlic) growing in Bulgaria has been studied. Thymidine (1), adenosine (2), astragalin (kaempferol-3-O-β-D-glucopyranoside (3), kaempferol-3-O-D-glucopyranosyl-7-O-D-glucopyranoside (4), kaempferol-3-O-D-neohesperoside (5), and kaempferol-3-O-D-neohesperoside-7-O-D-glucopyranoside (6) were isolated from the n-butanol extract and identified by different spectroscopic and spectrometric methods. Thymine (7), uridine (8), uracil (9) and 5-chloro-uridine (10) were detected in the same extract by GC-MS. This is the first report of the occurrence of 1, 2, 4, 7 – 10 in the flowers of A. ursinum. GC-MS of the volatile components of fresh flowers and leaves from the same plant revealed a high content of sulfur compounds, some of which are reported for the first time for A. ursinum. The antimicrobial activities of extracts from fresh flowers and leaves of A. ursinum have been tested; some extracts exhibited moderate antifungal properties.

Résumé :

The common wombat (Vombatus ursinus) lives in a mesic habitat whereas the hairy-nosed wombat (Lasiorhinus latifrons) inhabits a xeric habitat. The kidney structure of these two wombats was studied and it was found that kidney size, kidney weight, and kidney weight as a percentage of body weight, were larger in V. ursinus. However, relative medullary thickness, percentage medullary volume, and medullary thickness as a percentage of total thickness, were significantly greater in L. latifrons, suggesting that L. latifrons has a greater capacity to conserve water than does V. ursinus. The number of glomeruli and mean glomerular area were the same in both species whereas the mean diameter of the proximal and distal tubules was larger in V. ursinus. There were more proximal tubules per square millimetre in L. latifrons. The larger number of collecting ducts per square millimetre in the medullary region in L. latifrons indicates that the nephrons join the collecting ducts deep in the medulla, a feature that has been associated with increased urinary concentrating ability. Urinary pH was significantly lower, and urinary ammonia, creatinine and sodium levels were higher, in L. latifrons, as were plasma sodium and chloride levels. These data suggest that L. latifrons has a greater capacity to conserve water.

Résumé :

Abstract. The purpose is to study the phenology, morphometry, reproductive biology, and propagation characteristics of the following species and samples of wild ramson onion: A. microdictyon Prokh. (Bashkir sample), A. victorialis L. (Moscow and Syktyvkar samples), A. ursinum L. (Moscow sample), A. ochotense Prokh. (Syktyvkar and Irkutsk samples). Methods. The study of wild ramson samples was carried out in 2016-2020 under the conditions of the culture in the South-Ural Botanical garden-institute of the UFRC RAS (Bashkir Cis-Urals, northern forest-steppe). The study of the seasonal rhythm of growth and development was carried out according to the method of phenological observations by I. N. Beideman and I. V. Borisova. Determination of winter hardiness and resistance to adverse weather conditions, pests and diseases, reproduction coefficient and seed productivity was carried out according to generally accepted recommendations. Results. According to the phenorhythmotype, the studied species are short-growing, spring-early-summer flowering. A. ursinum – ephemeroid, A. microdictyon, A. ochotense and A. victorialis – hemi-ephemeroid. The flowering phase occurs in late May-early June. The duration of flowering of wild ramson samples by year is 13-22 days. Seed maturation occurs in July. A. ursinum vegetation ends in July, the remaining samples-in August. The largest number of fruits and seeds are allocated samples of A. victorialis and A. microdictyon, the smallest – A. ursinum. Samples of A. microdictyon, A. ursinum and A. victorialis have a high percentage of fruit blooming. The weight of 1000 seeds of A. microdictyon is 3.6 g, A. ursinum – 5.9 g, A. victorialis – 6.3–6.7 g, A. ochotense – 7.9–8.5 g. Wild ramson seeds when sown in the open ground do not germinate in the same year: autumn sowing sprouts in 17–18 months, spring – in a year. To accelerate germination, it is recommended to stratify seeds for 2.5–3 months at a temperature of 0–3 °C. Scientific novelty. Research work on the study of wild ramson onions in the region of the Bashkir Cis-Urals has not yet been carried out. These species of onions have a wide resource value, which was caused by the high relevance of these studies.

Résumé :

Coastal brackish and salt marshes in the High Arctic are very limited floristically and in areal extent. Small marshes located on the northeast coast of Devon Island are dominated by distinct zones of Puccinellia phryganodes nearest the sea with Carex ursina, C. stans, Dupontia fisheri, and Alopecurus alpinus dominated zones landward. Soil salinity and chloride ion content increase seaward, but plant water potential becomes less negative, opposite to the expected pattern. Fresh water from the melting pack ice forms a lens over the more dense seawater below it. This meltwater dilutes the salts in the upper soil layer, creating a low salinity condition for the plants that inhabit the zones nearest the sea. We hypothesize that it is this "fresh" water that comes into contact with the roots of Puccinellia and Carex ursina, and thus, less-negative water potentials are maintained in these species. Although plant zonation can be explained in part by such considerations, we conclude that edaphic characteristics are not the only factors involved. A number of hypotheses are entertained.

Résumé :

Trailing blackberry cultivars, such as `Marion', can be traced to relatively few chance selections of Rubus ursinus Cham. & Schlecht. Wild R. ursinus offer a range of horticulturally desirable traits to breeders, from high fruit quality to improved cold hardiness. Cuttings from 460 plants, representing 20 populations in southern British Columbia, Washington, and Oregon, collected in 1993. Rooted clones were planted in 1994 in a replicated field trial to assess morphological variation. A greenhouse study was also undertaken, with 10 clones represented from each site, in two replications. Preliminary data from the greenhouse and field studies show variability in the following morphological characters: Glandular hairs; cane and prickle color; cane diameter; prickle density; internode length; leaf color, size, shape and density; and senescent leaf drop and color change. Floricane morphology will be assessed in 1995. Analysis of these data will determine relative genetic distances among the populations and enhance the understanding of the diversity available in R. ursinus.
