Résumé :
Recent technological advances in computer hardware, software, and image processing have led to the development of an automated license plate reader (ALPR). This equipment was developed primarily for enforcement and security applications, such as monitoring parking garages or border crossings. Because license plate data are used in several transportation planning studies, ALPRs have the potential to increase the quality and efficiency of many typical activities of transportation planning agencies. The key performance attributes of an ALPR with respect to the specific needs of transportation planning are determined. The following general needs are investigated: ( a) the specific license plate data requirements of transportation planning studies; ( b) the effect of the equipment on traffic operations and safety; and ( c) special equipment characteristics required because of the temporary nature of transportation planning and the constraints of transportation planning agencies. In addition, an existing ALPR was tested in situations likely to be encountered in transportation planning applications. Technical specifications for an ALPR for transportation planning are developed. These specifications can be used to provide motivation and direction for the future development of an ALPR for transportation planning. Finally, the technical challenges to developing the ALPR are discussed.

Résumé :
Floral visitors of seven species of Oxypetalum were registered in Viçosa, State of Minas Gerais. O. appendiculatum, O. banksii subsp. banksii, O. alpinum var. alpinum and O. pachyglossum are pollinated by wasps, being Polybia ignobilis (Vespidae) a pollinator of these four species. It seems that P. ignobilis promotes interspecific pollinations mainly between O. alpinum var. alpinum and O. pachyglossum, two species with very similar floral morphology. O. jacobinae, O. mexiae and O. subriparium are pollinated by bees. Wasps and bees carry one, two, three or several pollinaria in the mouthparts. O. mexiae, an endemic species in Viçosa, seems to present reproductive limitations, since its flowers are seldom visited.

Texte intégral
Résumé :
The phenology of flowering was studied in an experimental garden, on diploid and tetraploid populations of Anthoxanthum alpinum A. & D. Löve and of A. odoratum L. of central and southern Europe and also in situ in a contact zone between diploid A. alpinum and tetraploid A. odoratum. In the experimental garden, the phenological parameters were studied at the individual level (onset of flowering) and at the population level (dates on which each population showed opened anthers for the first time on 40, 50, 60, 70, or 80% of the plants). Anthoxanthum alpinum flowered earlier than A. odoratum, regardless of the respective ploidy level of the two taxa. The average time lag between the appearance of the stigma and that of the stamens was about 2 days for the two A. alpinum taxa and 6 days for those of A. odoratum. Flowering was spread over the longest period for the tetraploid A. odoratum, which shows the great phenological variability of this taxon. The in situ study confirms the precocity of A. alpinum. The phenological differentiation within this polyploid complex probably coincides with the individualization of the two diploid taxa but precedes their respective polyploidization phases.

Résumé :
Two apomictic, polyploid (x=9) species in Hieracium sect. Alpina are described from the Western Bieszczady Mountains, Eastern Carpathians, Poland, and illustrated with photos of the holotypes. These are H. jasiewiczii (4x) which combines the morphological features of H. alpinum and H. bifidum, and H. wojcickii (4x) of presumably hybrid origin between H. alpinum and H. pseudobifidum. Both new species are probably relicts originated from diploid, sexual H. alpinum with a wider primary range covering also the Western Bieszczady Mountains, which presently occurs only in the Romanian and Ukrainian Carpathians.

Texte intégral
Résumé :
Hieracium alpinum var. tubulosum Tausch (1828: 63) was raised to species rank as H. tubulosum (Tausch) Tausch (1837: 68), an illegitimate homonym of H. tubulosum Lamarck (1786: 367). The latter is a different, unrelated species pertaining to the H. intybaceum aggregate and described from the Alps, whereas Tausch’s taxon is endemic to the Sudetes and belongs to the H. alpinum aggregate (Chrtek, 1997). Hieracium tubulosum (Tausch) Tausch differs from other central European species of the H. alpinum aggregate by having tubular florets, so that the replacement name proposed below is etymologically appropriate.

Résumé :
The pollen grains of Indian Alangium Lam. Show interesting morphological features. In the present paper, the pollen of four species, viz., Alangium alpinum (Clarke) Smith, A. barbatum (R. Br.) Baill, ex Kuntze, A. chinense (Lour.) Harm. and A. salvifolium (L.) Wangerin have been studied under light and scanning electron microscopes. Alangium alpinum distributed in the eastern Himalaya, has 3-4 colporate pollen with characteristic striate sculptured exine. Whereas, A. chinense is distributed throughout the Himalaya as well as the plains has regulate-reticulate sculptured exine with aperture similar to A. alpinum, A. barbatum is sporadic in Assam and has 3-colporate pollen with faint striate sculpturing. A. salvifolium happens to be the most widely distributed species extending from Himalayan foothills to extreme south of the Indian Peninsula as well as Andaman Island and has 3-6 porate-porate-brevicolporate apertures. Pollen grains of A. salvifolium subsp. Sundanum (Miq.) Bloembergen show gemmate-granulate sculpturing whereas, in A. salvifolium subsp. Salvifolium (L.) Wangerin the sculpturing is regulate-verrucate-gemmate-granulate. SEM studies reveal secondary ornamentation in A. alpinum, A. barbatum and A. salvifolium and interesting variations in the orientation of muri in case of A. chinense.

Résumé :
The aporphine alkaloid magnoflorine, known as a constituent of Asian Epimedium species, was isolated for the first time from the wild growing European species, Epimedium alpinum L. Identification was done by comparison with literature data. The HPLC method was applied for the determination of the content of the alkaloid in methanolic extracts of plant material. The underground part of E. alpinum contains 1-2 % of magnoflorine, while its content in methanolic extracts was 9.2-11.8 %. The aerial part of the plant contains less alkaloid (0.06-0.12 %), while the magnoflorine content in methanolic extracts of the aerial part was 0.4-0.8 %. Probably, the high content of magnoflorine in the methanolic extracts of underground parts of E. alpinum influences its dose-dependent cytotoxic activity (300 ?g/ml; 39 % survival of cells in an experimental K562 cell culture).

Der Innsbrucker Arbeitsgruppe um Hermann Stuppner verdanken wir eine intensive Analytik der Inhaltsstoffe und ihrer pharmakologischen Aktivitäten.In der Alpenregion wurde das Kraut von Leontopodium alpinum Cass. bzw. daraus hergestellte Zubereitungen arzneilich eingesetzt bei Bauchschmerzen, Angina, Bronchitis, Diarrhoe und Dysenterie; heute werden Edelweiß bzw. daraus gewonnene Extrakte nur noch in homöopathischen Mitteln, in kosmetischen Zubereitungen und vereinzelt in Lebensmitteln angewendet. Die phytochemische Untersuchung der gesamten Pflanze ergab ein breites Spektrum an Naturstoffen, wobei die Leontopodiumsäuren, Caffeoylchinasäuren, Flavonoide, Lignane, Cumarine sowie ein ätherisches Öl mit zahlreichen Terpenkomponenten charakteristisch sind. Moderne pharmakologische Untersuchungen bestätigen für Extrakte aus Edelweiß und daraus isolierte Einzelstoffe antiinflammatorische, analgetische und antimikrobielle Wirkungen sowie eine Hemmung der Peristaltik des Gastrointestinaltrakts und damit letztendlich die volksmedizinischen Anwendungsgebiete der Krautdroge von L. alpinum.

Résumé :
Four wild Ribes species (Ribes alpinum L., Ribes petraeum Wulf., Ribes rubrum L., and Ribes uva- crispa L.; all 2n = 2x = 16) were surveyed for their chromosome and genome organisation. Their genome size was assessed using flow cytometry. Ribes alpinum had 5.3% more nuclear DNA than did the three other species, whose average was 2C = 1.91 pg with 40.4% GC. In addition, GC- and AT-rich heterochromatin and rDNA (18S–5.8S–26S and 5S) patterns were studied using fluorochrome banding and double-target fluorescence in situ hybridization (FISH), respectively. Only GC-rich heterochromatin was detected, co-localizing with 18S–26S rDNA. Fluorochrome banding and FISH patterns revealed marked differences between species. Ribes alpinum and R. uva-crispa differed from R. rubrum and R. petraeum by the number of 18S–26S sites and the localization of 5S rDNA. Ribes alpinum and R. uva-crispa were differentiated by the number of 5S sites. Ribes rubrum and R. petraeum also differed by the number of 5S sites and by the size of the GC-rich band on the satellite chromosome pair. These results should contribute to a better understanding of phylogenetic relationships among these species.Key words: Ribes, flow cytometry, fluorochrome banding, FISH, rDNA, NORs.

Résumé :
Hedysarum alpinum L. var. americanum Michx. (American hedysarum) is indigenous to parts of Saskatchewan. Plants grown from seeds collected at five locations in central Saskatchewan were transplanted into a nursery at Saskatoon, Saskatchewan and a study of the nutritive value of individual plants was undertaken to determine the potential value of American hedysarum as a forage legume for the northern Canadian prairies. Leaves and stems (analyzed separately) showed marked differences in chemical composition. However, they did not differ in the in vitro organic matter digestibility (OMD). American hedysarum plants had a much higher tannin content than alfalfa or birdsfoot trefoil plants grown at the same location. This may account for the relatively low OMD of this species. The protein and fiber fractions (of H. alpinum) compared favorably with those of alfalfa. Improvement by breeding for reduced tannin content would be necessary before American hedysarum would be acceptable as a forage crop.Key words: Hedysarum alpinum L. var. americanum Michx., American hedysarum, forage, tannin, in vitro digestibility, early growth

Résumé :
Leontopodium alpinum Cass. (edelweiss) is recognized as a frequent constituent of anti-aging skin care products, providing increased antioxidant and anti-inflammatory defense. Considering the growing demand and the protected status of edelweiss in many countries, alternative methods of production have been developed, one of them being callus culturing. This study reports the phytochemical composition of a methanolic extract of L. alpinum callus cultures, characterized by liquid chromatography coupled to ion-mobility high resolution mass spectrometry (UPLC/IM-HRMS). The methanolic extract exhibited strong free radical scavenging activity (122.19 ± 7.28 mg AAE/g dw), while the quantitative evaluation revealed that four major constituents (phenylpropanoid derivatives) represent 57.13% (m/m) of the extract. Consequently, a screening of antiproliferative effects was performed on ten cancer cell lines, representative of prostate, colon, lung and breast cancer, showing inhibition of colony formation in all cases. These results provide a comprehensive phytochemical characterization of L. alpinum callus cultures using advanced IM-HRMS, while the in vitro explorations confirmed the potent antioxidant properties of edelweiss which are worth exploring further in cancer prevention.

The synthesis and performance of a molecularly imprinted polymer (MIP) designed to enable the clean-up of the interferences existing in alprazolam (Alpra) drug samples is described. The MIP was synthesized using non-covalent molecularly imprinted method. Nimetazepam (Nimet), which has a similar chemical structure as the major impurities in Alpra drug samples, was used as the dummy template. Methacrylic acid was used as the monomer. Both the affinity and selectivity of the MIP for Nimet and structurally related compounds were examined through batch-rebinding studies. The specific binding amount of Nimet was determined to be 11.4 mg•g-1. The MIP was used as the sorbent in solid phase extraction (MI-SPE) and methanol was used as the washing solvent for the clean-up of Nimet in the Alpra complex samples. The effective clean-up of Nimet was achieved, with a recovery > 90% for Alpra, in the stimulated samples.

Résumé :
Abstract Variation of 9 isozyme systems was studied in Polish populations of 3 species of the genus Anthoxanthum: the native A. odoratum s. str. L. and A. alpinum Á. Löve & D. Löve, as well as the alien A. aristatum Boiss. Results of this study show that A. odoratum is characterized by a high isozyme variability of lowland populations, weakly correlated with habitat type, and partial genetic distinctness of montane populations. Moreover, 5 isozyme markers have been identified (Pgi-2, Dia-2, Mdh, Idh, Pgm) for the allopolyploid A. odoratum. Populations of A. aristatum are highly polymorphic (P = 98%). The observed isozyme differentiation of its populations (FST = 0.087) is low and gene flow between them (Nm = 5.314) is high. The genetic variation reflects environmental variation only to a small extent and is not significantly related to the phase of chorological expansion of this species. Altitudinal vicariants, A. alpinum and A. odoratum, are characterized by morphological and isozymatic distinctness, indicating their reproductive isolation. In populations of A. alpinum, polymorphism is high (P = 76.92%), differentiation among populations is moderate (FST = 0.198), and gene flow between populations along the altitudinal transect (Nm = 1.709) is relatively low

Résumé :
Abstract Three Anthoxanthum species are found in Poland: the native A. odoratum L. s. str. and A. alpinum Á. Löve & D. Löve, and the alien A. aristatum Boiss. Major problems within this genus concern: (1) population variation of the native A. odoratum, representing various phases of ecological expansion to anthropogenic habitats; (2) population variation of A. odoratum and A. alpinum along the altitudinal transect; and (3) variation between populations of A. aristatum colonizing new areas and habitats outside its natural range of distribution (chorological expansion). In this study, morphological and anatomical variation of the three Polish Anthoxanthum species was analysed in detail. The variation of A. odoratum and A. aristatum was analysed in respect of environmental differences: habitat types and soil parameters. In the Babia Góra massif, variability distribution along the altitudinal transect was analysed for two vicariants: A. odoratum and A. alpinum. A odoratum in this massif does not cross the upper forest limit (i.e. forest line), and lower montane populations are morphologically very similar to lowland populations. Morphological and anatomical differences were detected between populations of A. alpinum along the altitudinal transect in the Babia Góra massif, with distinct upper montane populations. Moreover, clear morphological differences were found between the two altitudinal vicariants. Lowland populations of A. odoratum are characterized by great morphological variation, only weakly correlated with the type of occupied habitat and the phase of ecological expansion. The detected morphological variation reflects only to a limited extent the environmental variation of occupied habitats, and is not significantly correlated with the phase of chorological expansion. Some soil parameters are significantly correlated with some morphological characters studied in all the Anthoxanthum species. The analysed anatomical features of stems and leaves show continuous variation in the three species.

Résumé :
Polyploidy has played a crucial role in the evolution of many plant taxa, namely in higher latitudinal zones. Surprisingly, after several decades of an intensive research on polyploids, there are still common polyploid species whose evolutionary history is virtually unknown. Here, we addressed the origin of sweet vernal grass (Anthoxanthum odoratum) using flow cytometry, DNA sequencing, and in situ hybridization-based cytogenetic techniques. An allotetraploid and polytopic origin of the species has been verified. The chromosome study reveals an extensive variation between the European populations. In contrast, an autopolyploid origin of the rarer tetraploid vernal grass species, A. alpinum, has been corroborated. Diploid A. alpinum played an essential role in the polyploidization of both European tetraploids studied.

Résumé :
For the first time, chromosomal polymorphism in karyotypes of three species from the section Hedysarum (= syn. Gamotion) of the genus Hedysarum L. (Fabaceae) grown in Southern Siberia has been studied with the useof molecular cytogenetic markers. This comparative molecular cytogenetic analysis revealed high similarity in morphology of chromosomes in H. alpinum L., H. austrosibiricum B. Fedtsch. and H. theinum Krasnob. as well as in patterns ofdistribution of 45S and 5S rDNA loci in their karyotypes confirming their close relationships. Considerable intra-specificpolymorphism on 45S rDNA chromosome localization was detected in H. theinum. In karyotype of H. alpinum, unlikethe other two species, two chromosome pairs bearing 5S rDNA locus were observed which could be used as additionalspecies-specific markers.

Résumé :
We examined the occurrence of Neotyphodium endophytes in native grasses from Argentina using both herbarium material and plants collected from the field. Neotyphodium endophytes were detected in 34 out of more than 150 host species examined throughout the country. The incidence of infection was highly variable within many of the species. We examined the relationship between incidence of endophyte and environmental conditions in four host species, Bromus setifolius from Santa Cruz, Phleum alpinum and Poa rigidifolia from Tierra del Fuego and Poa bonariensis from the Pampean region. The results suggest that each endophyte-host association seems to be affected in different ways by environmental factors. B. setifolius only contained endophyte in moist rather than dry regions, while in contrast, Ph. alpinum showed the highest endophyte incidence in the driest sites. Endophyte incidence in P. rigidifolia was highest where soil fertility was high, and P. bonariensis contained the most endophyte in high pH rather than low pH soils. Field observations suggest that in poor growing conditions, such as those of the extra-Andean Patagonia, or highly acidic soils, the association is not favoured leading to a decrease in the endophyte frequency of infection or even to the complete loss of the association. Keywords: Bromus setifolius, native grasses, Phleum alpinum, Poa bonariensis, Poa rigidifolia, South America

Résumé :
Ribes alpinum L. has all useful properties (optimal combination of vitamins, sugars, organic acids, pectins) and, due to this, it deserves to be introduced into the breeding process. It was found that, in the conditions of the Belgorod region, Alpine currant develops normally and passes all phenological phases. The long-term variation in the timing of the phase onset is 25 days on the average. The studied forms of Ribes alpinum L. belong to phenologically early plants. In the cultivation for decorative purposes in the conditions of the Belgorod region, 5 forms are identified: large-fruited, compact, erect, erect dissected-leaved and spreading. There are 8 Alpine currant varieties (Evrika, Vorskla, Mulatka, Theodor, Dunyasha, Uslada, Krasnyi Schar, Zara) with a complex of economically valuable characteristics.

Résumé :
The chemical composition and digestibility of plants selected by Norwegian reindeer (Rangifer t. tarandus) on the sub-Antarctic island of South Georgia (SG) were investigated in the austral summer and compared with two qualities of standard grasses of Phleum pratense of European origin. Paridiochola flabellata, Poa pratense, Poa annua, Deschampsia antarctka, and Phleum alpinum collected on SG contained 14.8, 17.6, 22.8, 16.1 and 10.1% respectively of crude protein of dry matter (DM). Aceana magellanica also collected on SG contained 19.8% of crude protein and 18.8% of water-soluble carbohydrates (WSC) of DM, while the tussock grass P. flabellata, contained as much as 29-3% of WSC of DM. Total plant cell-wall contents (CWC), including cellulose, hemi-cellulose and lignin in P. flabellata, P. pratense, P. annua and P. alpinum were 53.2, 49.6, 41.7 and 40.4% of DM respectively, while A. magellanica contained only 17.5% of DM CWC. The lignin concentrations of plants analysed varied between 1.2 and 3.2% of DM. Mean in vitro dry matter digestibility (IVDMD) of selected plants ranged from 70% in P. flabellata to 83% in P. alpinum after 48 h incubation in rumen fluid from these reindeer. In contrast, the IVDMD of the poor and high quality standard grass Phleum pratense were 54% and 73% of DM, respectively. The forage eaten by reindeer on SG in summer was of high quality, with low lignin content, moderate protein concentration and high degradability in rumen fluid.

Résumé :
In an attempt to know the phylogeny of timothy (Phleum pratense), the cultivated species and two wild relatives, Phleum alpinum and Phleum bertolonii, were karyotyped with conventional and Giemsa C-banding methods. In the hexaploid P. pratense (2n = 6x = 42), two sets of seven chromosomes were indistinguishable from each other both in morphology and in banding patterns and the third set of seven was found to be differentiated from them. Two genomes, A and B, were tentatively established. The banded karyotype in diploid P. alpinum (2n = 2x = 14) was close to the A genome, which was tetraploid in P. pratense, and the karyotype in P. bertolonii (2n = 2x = 14) was analogous to the B genome in P. pratense, which suggests these species were the genome donors of P. pratense.Key words: chromosome, genome, allopolyploid, Giemsa C-banding.

Zusammenfassung Der Beitrag geht der Frage nach, wie große und modern eingerichtete Familienhäuser und Villen in Erzählungen vom Sehnsuchtsort zum Angstraum werden können. Schlösser und Burgen werden vergleichend herangezogen. Dabei wird vor allem das Zusammenspiel von modernen Sagen, Horrorserien und alltäglichem Erzählen betrachtet. Häusern ist eine eigene Folklore des Schreckens zu eigen, die auch menschliche Täter und Täterinnen umfasst. Das strukturelle Paradoxon von Immobilie und Mobilien, von statischer Ordnung und Bewegung wirkt sich auch auf die Erzählungen aus: Dem Traum vom ‚schöner Wohnen‘ ist auch der Alptraum eingeschrieben und kann diesen überlagern. Erzählungen geben darüber Auskunft, beziehen sich in ihren Bilderwelten aufeinander, unterlaufen und verstärken diese und bilden das Spannungsfeld ‚Sehnsuchtsort – Angstraum‘ mit.
