The Flora Of Erciyes Dağı (Kayseri, Turkey), Cem Vural, Zeki̇ Aytaç
The Flora Of Erciyes Dağı (Kayseri, Turkey), Cem Vural, Zeki̇ Aytaç
Turkish Journal of Botany
This research details the flora of Erciyes Dağı, situated in the province of Kayseri in Central Anatolia, entirely within the Irano-Turanian phytogeographic region. A total of 2554 plant specimens were collected from the research area between 1996 and 2002. An evaluation of these specimens revealed 89 families, 433 genera and 1170 taxa (1116 species, 31 subspecies and 23 varieties). Of the 1170 taxa, 11 are pteridophytes, 12 gymnosperms and 1147 angiosperms (979 dicotyledons and 168 monocotyledons). Of these taxa, 36 are cultivars. According to the number of taxa, Asteraceae, Fabaceae and Poaceae are the largest families (137 Asteraceae, 116 Fabaceae, …

This study is a further contribution to a series describing perforated ray cells and the wood anatomy of some Dicotyledons families and their taxa indigenous to Turkey: Berberis vulgaris L. (Berberidaceae), Colutea armena Boiss & Huet (Fabaceae), Coronilla emerus L. (Fabaceae), Chamaecytisus hirsutus (L.) Link. (Fabaceae), Cytisus villosus Pourr. (Fabaceae), Hedera helix L. (Araliaceae), Paliurus spina-christii Mill. (Rhamnaceae), Pistacia lentiscus L. (Anacardiaceae), Salix triandra L. subsp. triandra L. (Salicaceae), Sambucus nigra L. (Caprifoliaceae), Staphylea pinnata L. (Staphyleaceae), Tamarix smyrnensis Bunge (Tamaricaceae), Vitis silvestris Gmelin. and V. vinifera L. (Vitaceae). Perforated ray cells were found either isolated or together in groups, …

Isoprene is the dominant volatile organic compound produced in many forest systems. Uncertainty in estimates of leaf level isoprene emission rate stems from an insufficient understanding of the patterns and processes controlling isoprene emission capacity in plant leaves. Previous studies suggest that variation in isoprene emission capacity is substantial; however, it is not known at what scale emission capacity is the most variable. Identifying the sources of variation in emission capacity has implications for conducting measurements and for model development, which will ultimately improve emission estimates and models of tropospheric chemistry. In addition, understanding the sources of variation will help …
First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles
First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles
The Prairie Naturalist
The evening bat (Nycticeius humeralis) occurs throughout the eastern and southeastern United States and into extreme northeastern Mexico, approximately 42° to 18° N latitude (Watkins and Shump 1981). Although records of females are common, records of adult male evening bats are rare in the northern portion of the species range (Watkins 1969, Watkins 1972). Jones et al. (1967) suggested that adult males might not accompany females to at least some parts of the parturient range. As part of a larger study (Davis 2003) we surveyed bats on Fort Leavenworth Military Reservation (FLMR), Leavenworth County, Kansas in July 2002 …
2005 Virginia Wildflower Of The Year: Bloodroot, Sanguinaria Canadensis, W. John Hayden
2005 Virginia Wildflower Of The Year: Bloodroot, Sanguinaria Canadensis, W. John Hayden
Biology Faculty Publications
Bloodroot is an herbaceous perennial that grows from a persistent, branched underground stem or rhizome. Early each spring, while the forest canopy is still bare, each well-developed rhizome tip produces one leaf and one flower stalk. The leaf is kidney-shaped in its overall outline, but it is also divided into a pattern of rounded lobes and sinuses, rendering a complex overall shape. At flowering time, bloodroot leaves form a loose vertically-oriented collar around the flower stalk with the bluish-green lower leaf surface forming the outside of the collar; as the season progresses, the leaves open flat and expand to their …
Analysis Of Molecular Variation In The Federally Endangered Astragalus Jaegerianus (Fabaceae, Papilionoideae): A Species With A Restricted Geographic Range, George Floyd Walker
Analysis Of Molecular Variation In The Federally Endangered Astragalus Jaegerianus (Fabaceae, Papilionoideae): A Species With A Restricted Geographic Range, George Floyd Walker
Theses Digitization Project
The purpose of this study is to investigate the level and distribution of genetic variation in Astragalus jaegerianus by using molecular markers. The objectives of the study are: to estimate levels of genetic variation within and among populations of Astragalus jaegerianus; to test the hypothesis that levels and patterns of genetic variation in species of restricted ranges and few individuals is low and partitioned at the population level; and to discern whether, or how well, genetic partitioning of Lane Mountain milk vetch correlates with its geographic partitioning in the field.

Early generation selection experiments typically involve several hundred to thousands of lines. Various systematic and statistical techniques have been developed to increase effectiveness and efficiencies in such experiments, including the development and application of spatial statistical models. In this study, mixed model equations were used to provide least squares means (LSMEANs) and best linear unbiased predictors (BLUPs) and compare selection effectiveness and efficiencies to observed (Y) and true values in simulated experiments varying in size (10 X 10, 20 X 20 and 30 X 30 grids), control plots densities (0, 5, 10, 20, and 50%), control plot arrangements (high, medium, …
