Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda
Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation combines investigation of the large-scale responses of bryophyte species diversity and distribution with small-scale physiological adaptations to global change. These two areas of inquiry are linked because one way to predict plant species responses to global change is to examine their distribution across current ecological gradients produced by factors such as latitude and elevation. By examining these biogeographic patterns one can identify those species that have a narrow tolerance and therefore are most sensitive to change. Selected bryophytes might then be used as indicator species in long-term monitoring programs. Where historical data exist, these can be used to …
Ponderosa Pine Revisited, J. Robert Haller, Nancy J. Vivrette
Ponderosa Pine Revisited, J. Robert Haller, Nancy J. Vivrette
Aliso: A Journal of Systematic and Floristic Botany
We here recognize a new variety, Pinus ponderosa var. pacifica, in the Pacific portion of the species' distribution and present a new combination for Washoe pine as a variety, Pinus ponderosa var. washoensis. In this treatment, we reject the neotype of Pinus ponderosa selected by Lauria and designate instead the branch collected by David Douglas with mistletoe (Arceuthobium campylopodum) as lectotype for Pinus ponderosa. Table 1 compares the distinguishing characters of the North Plateau (typical) variety, the Pacific variety, and the Washoe variety of Pinus ponderosa with a closely related species, Pinus jeffreyi. Figure …

Bacterial soft rot disease of Aloe caused by heterogeneous genus Erwinia was reported from different parts of the world. In the recent past the genus underwent major taxonomic modifications. In the present study, four Aloe pathogenic bacterial strains isolated from India, The Netherlands and Yugoslavia have been compared. Different cultural, biochemical, physiological and pathological characters and protein/lipid profiles indicated that the strains belonged to two different genera, Pectobacterium and Dickeya. Species specific amplification of pel gene sequences also supported this. Phylogenetic analysis of rRNA gene (rDNA) sequence placed these Dickeya strains close to D. dieffenbachiae and D. zeae. On the …

Turkish Journal of Botany
In this study, Pulsatilla Mill., which was considered a subgenus of the genus Anemone L. in Flora of Turkey, is accepted as a separate genus. Pulsatilla albana (Steven) Bercht. & J.Presl subsp. albana and P. violacea Rupr. subsp. violacea are declared as new records for the flora of Turkey. Anemone albana Steven subsp. armena (Boiss.) N.Busch, which was already known from Turkey, is accepted as a synonym of Pulsatilla violacea subsp. armena (Boiss.) Luferov. Descriptions, distribution maps, and identification keys are provided for these taxa in order to aid in the distinguishing of the genera Anemone and Pulsatilla as well …
Cicer Uludereensis Dönmez: A New Species Of Cicer (Chickpea) (Fabaceae) From Around The Fertile Crescent, Se Turkey, Ali̇ Aslan Dönmez
Cicer Uludereensis Dönmez: A New Species Of Cicer (Chickpea) (Fabaceae) From Around The Fertile Crescent, Se Turkey, Ali̇ Aslan Dönmez
Turkish Journal of Botany
The genus Cicer L. includes an important crop plant, chickpea, which has been used as a protein source since prehistoric times. Specimens of a native Cicer have been collected and described from south-east Turkey. This new species, Cicer uludereensis Dönmez sp. nova, is distinct from a closely allied species, Cicer isauricum P.H.Davis, by its fine and more numerous teeth per leaflet, larger stipules, and narrower fruit with almost smooth seed surface. An illustration and a distribution map of the new species are provided and observations on the population are discussed.

Turkish Journal of Botany
The pollen morphology of 48 specimens of 6 species (9 taxa) of the genus Achillea L. sect. Achillea (Asteraceae), A. nobilis L. subsp. neilreichii (A.Kern.) Formánek, A. nobilis subsp. densissima (O.Schwarz ex Bässler) Hub.-Mor., A. nobilis subsp. sipylea (O.Schwarz) Bässler, A. nobilis subsp. kurdica Hub.-Mor., A. filipendulina Lam., A. clypeolata Sm., A. coarctata Poir., A. biebersteinii Afan., and A. cappadocica Hausskn. & Bornm. distributed in Turkey were investigated using light (LM) and scanning electron microscopy (SEM). The pollen grains were oblate-spheroidal, prolate-spheroidal, subprolate and generally tricolporate, though at times tetracolporate or even pentacolporate. The size of the grains varied, ranging …

A New Genus, Turanecio, Of The Asteraceae (Tribe Senecioneae), Ergi̇n Hamzaoğlu, Ümi̇t Budak, Ahmet Aksoy
A New Genus, Turanecio, Of The Asteraceae (Tribe Senecioneae), Ergi̇n Hamzaoğlu, Ümi̇t Budak, Ahmet Aksoy
Turkish Journal of Botany
Turanecio Hamzaoğlu, a new genus of the Asteraceae, is described. Ten species are included, previously referred to Senecio L., Cineraria L., or Iranecio B.Nord. This genus belongs to the "Quadridentate Group" of the subtribe Senecioninae, because of the 4-lobed disc florets. The new genus closely resembles Dolichorrhiza (Pojark.) Galushko, but differs by the thickish rhizome, the short-sagittate anther bases, the style branches with papillate lower surface, and in possessing a persistent pappus. Turanecio is centred in Turkey, with species in the Caucasus, Iran, and Iraq.
Seed Morphology And Anatomy Of The Mediterranean Pentamerous Species Of Erica (Ericaceae), Jaime Fagundez, Jesus Izco
Seed Morphology And Anatomy Of The Mediterranean Pentamerous Species Of Erica (Ericaceae), Jaime Fagundez, Jesus Izco
Turkish Journal of Botany
The species of the "Pentapera group" are distinguished from the rest of the European and Mediterranean Erica L. species by having 5 corolla lobes and sepals instead of 4, and 10 stamens instead of 8. The genus Pentapera Klotzsch was proposed for these taxa but recent studies regards it as part of Erica. Two species are recognised: Erica sicula Guss. and E. bocquetii (Peşmen) P.F.Stevens, and 3 subspecies have been described within E. sicula. This taxonomic treatment is still under discussion and relationships with other species have been poorly discussed. Seed morphology of the 2 species and the 3 subspecies …

Fruit And Seed Morphology Of Six Species Previously Placed In Malcolmia (Brassicaceae) In Turkey And Their Taxonomic Value, Ayla Kaya, Murat Ünal, Fevzi̇ Özgökçe, Beki̇r Doğan, Esra Marti̇n
Turkish Journal of Botany
The fruit and seed morphologies of 6 species previously placed in the genus Malcolmia W.T.Aiton were examined with stereomicroscopy and scanning electron microscopy (SEM) in order to determine the significance of fruit and seed features as taxonomic characters. This study presents macro- and micromorphological characters, including fruit and seed shape, size, colour, fruiting pedicel size, fruit hair and density, seed coat pattern, epidermal cell shape, and anticlinal and periclinal cell walls. The results showed that the morphological characteristics of the fruit and seed could be used as criteria to distinguish genera and tribes. The investigated features of specimens indicated that …
