Botanist In Death Valley, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

Abstract

This book details the author’s trips to Death Valley, along with general ecological information about the region. Explorations by other natural historians are also recounted. Death Valley and its surrounding mountain ranges are stark and appear to lack vegetative cover, but that appearance is deceiving. The ranges and valley support a great diversity of living things, both plants and animals. Pages 10–17 contain photographs of various landscapes. Pages 18–20 list the plant species collected in Death Valley, 1970–1983. Voucher specimens are available for study at Stanley L. Welsh Herbarium, Brigham Young University.

The Effect Of Historical Legacy On Adaptation: Do Closely Related Species Respond To The Environment In The Same Way?, Rachel Prunier, Kent E. Holsinger, Jane E. Carlson

EEB Articles

The many documented examples of parallel and convergent evolution in similar environments are strong evidence for the role of natural selection in the evolution of trait variation. However, species may respond to selection in different ways; idiosyncrasies of their evolutionary history may affect how different species respond to the same selective pressure. To determine whether evolutionary history affects trait-environment associations in a recently diverged lineage, we investigated within-species trait-environment associations in the white proteas, a closely related monophyletic group. We first used MANOVAs to determine the relative importance of shared response to selection, evolutionary history, and unique responses to selection …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The pollen morphology of 18 species from 12 genera of Chenopodiaceae native to Mongolia was studied. Plants were collected during field courses and research projects on useful plants and are deposited in the Herbarium of the Mongolian State University of Education. Chemical preparation was carried out in the Palynological Laboratories at the School of Natural Sciences of the Mongolian State University of Education and the Department of Palynology and Climate Dynamics of the University of Göttingen in Germany. The results show, that all investigated species are distinguishable in terms of pollen morphology bases on their pollen grain sizes, exine thickness …

Osnabrück Botanical Expeditions To Mongolia, Barbara Neuffer, Nikolai Friesen, Batlai Oyuntsetseg, Tseden Jamsran, Herbert Hurka

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Three botanical expeditions to Mongolia have been undertaken by the Botany Department of the University of Osnabrück in cooperation with the Botany Department of the National Mongolian University of Ulaanbaatar. The first expedition in 2000 took us to the Mongolian Altay, the second in 2001 to the Gobi and Gobi Altay, and the third in 2010 to East Mongolia including the Khingan Mts. (Numrug). In 2000, we were the first botanists being allowed to enter the border area between China and Russia in the Mongolian Altay since a long time, because this had been a prohibited area for decades. We …

Diploid Allium Ramosum From East Mongolia: A Missing Link For The Origin Of The Crop Species A. Tuberosum?, Batlai Oyuntsetseg, Frank R. Blattner, Nikolai Friesen

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In eastern Mongolia, a diploid close relative of the tetraploid (4x) crop species Allium tuberosum and its closest wild relative A. ramosum (4x) was found and characterized by karyotype analysis and with molecular marker techniques. An earlier analyses revealed A. ramosum to be sister of the crop but excluded it as its progenitor. At that time a putative diploid cytotype of A. ramosum was hypothesized as a potential progenitor taxon of the tetraploids. New phylogenetic analyses of chloroplast and nuclear DNA sequences including the recently found cytotype (A. aff. tuberosum) together with A. tuberosum and A. ramosum accessions …

Indicators Of Pasture Digression In Steppe Ecosystems Of Mongolia, Elena V. Danzhalova, S. N. Bazha, P. D. Gunin, Yu. I. Drobyshev, T. I. Kazantseva, A. V. Prischepa, N. N. Slemnev, E. Ariunbold

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The research shows that widely used key measures of vegetation structure (species diversity, projected cover and above-ground phytomass) are not always suitable as indicators of pasture degradation. Based on an analysis above-ground phytomass composition, new quantitative indices are offered that give a more realistic picture of rangeland condition in Mongolia.

Structure And Productivity Of Haloxylon Ammodendron Communities In The Mongolian Gobi, Tamara I. Kazantseva, Nikolay N. Slemnev, Pjotr D. Gunin, Sh. Tsooj

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Communities of Haloxylon ammodendron are widespread in the Mongolian Gobi where they play a significant role in biodiversity preservation. They occupy several main types of habitats, showing differences in density, projective cover, and productivity. Haloxylon ammodendron plays a similar, if not even more important role in the arid zone of Mongolia as the principal forest-making trees in the Northern part of the country. The complex set of quantitative parameters of Haloxylon ammodendron stands studied here in respect to temporal dynamics can serve as an indicator of both the vitality of desert ecosystems, and of environmental change.

Brown Midrib2 (Bmr2) Encodes The Major 4-Coumarate: Coenzyme A Ligase Involved In Lignin Biosynthesis In Sorghum (Sorghum Bicolor (L.) Moench), Ana Saballos, Scott Sattler, Emiliano Sanchez, Timothy P. Foster, Zhanguo Xin, Chulhee Kang, Jeffrey F. Pedersen, Wilfred Vermerris

Department of Agronomy and Horticulture: Faculty Publications

Successful modification of plant cell-wall composition without compromising plant integrity is dependent on being able to modify the expression of specific genes, but this can be very challenging when the target genes are members of multigene families. 4-coumarate:CoA ligase (4CL) catalyzes the formation of 4-coumaroyl CoA, a precursor of both flavonoids and monolignols, and is an attractive target for transgenic down-regulation aimed at improving agro-industrial properties. Inconsistent phenotypes of transgenic plants have been attributed to variable levels of down-regulation of multiple 4CL genes. Phylogenetic analysis of the sorghum genome revealed 24 4CL(-like) proteins, five of which cluster with bona fide …

Quantitative Trait Locus Analysis Of Saturated Fatty Acids In A Population Of Recombinant Inbred Lines Of Soybean, Xianzhi Wang, Guo-Liang Jiang, Marci Green, Roy A. Scott, D. L. Hyten, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Soybean [Glycine max (L.) Merr.] is an important crop which contributes approximately 58% of the world’s oilseed production. Palmitic and stearic acids are the two main saturated fatty acids in soybean oil. Different levels of saturated fatty acids are desired depending on the uses of the soybean oil. Vegetable oil low in saturated fatty acids is preferred for human consumption, while for industrial applications, soybean oil with higher levels of saturated fatty acids is more suitable. The objectives of this study were to identify quantitative trait loci (QTL) for saturated fatty acids, analyze the genetic effects of single QTL …

Natural Variation In Iron Use Efficiency And Mineral Remobilization In Cucumber (Cucumis Sativus), Brian M. Waters, Grace Troupe

Department of Agronomy and Horticulture: Faculty Publications

Aims: Iron (Fe) is an essential micronutrient, and plant-available Fe is often limited in alkaline soils. Fe deficiency chlorosis decreases plant growth and yield. Identification of germplasm with high and low Fe use efficiency will allow studies to better understand the genetic components for breeding Fe efficient varieties.

Methods: A screen using cucumber (Cucumis sativus) seedlings identified varieties that maintained contrasting levels of chlorophyll under Fe deficiency or limitation. A time course of mineral dynamics in cotyledons was conducted.

Results: The variety Ashley had the highest chlorophyll under Fe deficiency and per unit Fe in the leaf, while …

Possible New Arkansas Endemic Plant Revealed By Dna Sequence Analysis, A, K. P. Fawley, C. T. Witsell, M. W. Fawley, J. S. Breedlove, R. J. Brockman, A. C. Humphrey, J. M. Lawson, K. N. Mccallie, D. A. Prescott, J. T. Rushing, J. M. Whitaker

Journal of the Arkansas Academy of Science

Cardamine angustata var. ouachitana, a wildflower in the mustard family (Brassicaceae), was described by Smith in 1982 to include a form of Cardamine found only in the Ouachita Mountains of Arkansas. This variety is morphologically very similar to typical Cardamine angustata. The major difference noted by Smith for the two varieties was the complete lack of leaf hairs (trichomes) in the new variety, whereas typical Cardamine angustata normally possesses trichomes. However, Al-Shehbaz rejected the variety ouachitana and reduced it to synonymy with the typical C. angustata. The recommendation of Al-Shehbaz has been followed and the taxon Cardamine angustata var. ouachitana …

Shoot Morphology Of Eleven Alfalfa Populations, Jessica A. Schmuck

The Journal of Undergraduate Research

Alfalfa (Medicago sativa L.) is a major component of feed for dairy and beef cattle and one of the most productive forage species in North America. Alfalfa has been planted on millions of acres. More than 100 varieties have been developed in North America over the past 100 years. However, historically, alfalfa persistence under grazing in semiarid rangeland has generally been poor. Recently, it was discovered that naturally-selected populations of predominantly yellow-flowered alfalfa have been proven to be adapted to rangelands of western South Dakota and adjacent areas. A study was initiated in May 2006 to evaluate persistence and vigor …

Effects Of Arbuscular Mycorrhizal Inoculation On Biochemical Parameters In Capsicum Annuum Grown Under Long Term Salt Stress, Fazi̇let Özlem Çeki̇ç, Serpi̇l Ünyayar, İbrahi̇m Ortaş

Turkish Journal of Botany

Salt stress is an important environmental stress. Plants cope with salt stress with different strategies. In this study the effects of 2 different arbuscular mycorrhiza species (Glomus mosseae and G. intraradices) on some biochemical parameters in pepper plants (Capsicum annuum L. cv. Cumaovası) exposed to long term salt stress were studied. It was found that mycorrhizal inoculation increased RWC, P, total chlorophyll, and carotenoid content of pepper plants during salt application. The enzyme activities changed depending on the enzyme and salt stress application. The lowest MDA content was found in the plants inoculated with G. intraradices; however, there was no …
