The Plant Ontology Consortium (POC, http://www.plantontology.org ) is a collaborative effort among model plant genome databases and plant researchers that aims to create, maintain and facilitate the use of a controlled vocabulary (ontology) for plants. The ontology allows users to ascribe attributes of plant structure (anatomy and morphology) and developmental stages to data types, such as genes and phenotypes, to provide a semantic framework to make meaningful cross-species and database comparisons. The POC builds upon groundbreaking work by the Gene Ontology Consortium (GOC) by adopting and extending the GOC's principles, existing software and database structure. Over the past year, POC …
Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza
Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza
Journal of the Arkansas Academy of Science
Like most species of Passiflora, P. lutea is reported to produce one-day flowers with complicated floral movements and requires deposition of non-self pollen for fruit production. Medium sized bees are the most likely pollinators in central Texas. We report on a series of observations and experimental manipulations that compare the reproductive biology of P. lutea in central Arkansas to that reported previously from plants about 800 km distant in central Texas. We observed floral movements and floral visitors, compared fruit production of flowers available to pollinators versus flowers from which pollinators were excluded, and compared fruit production of flowers that …

Spiderwort Is Vnps Wildflower Of The Year, W. John Hayden
Spiderwort Is Vnps Wildflower Of The Year, W. John Hayden
Biology Faculty Publications
The VNPS 2008 Wildflower of the Year (WOY) is spiderwort (Tradescantia virginiana). This herbaceous perennial plant occurs throughout much of the eastern portion of the U.S. and is widespread in Virginia. Spiderwort blooms from April to July. The small flowers occur in clusters at the ends of the stems, atop several elongate bracts. Flowers have three petals that range from purple to rose or, rarely, white. Densely hairy stamens provide, perhaps, the easiest way to recognize spiderworts. Also, stalks of spent flowers droop below the flower cluster yielding an aspect reminiscent of spindly spider legs.
Use Of Passive Integrated Transponders In Hatchling Texas Horned Lizards, Scott E. Henke
Use Of Passive Integrated Transponders In Hatchling Texas Horned Lizards, Scott E. Henke
The Prairie Naturalist
The Texas horned lizard (Phrynosoma cornutum) is a Texas state-threatened species and acquisition of data related to the species' ecology is essential. To accomplish this task individual animals need to be marked. Many marking techniques are available for lizards, however the majority of techniques have been tested on adults only. Studies involving hatchling and juvenile horned lizards are scarce due to problems associated with marking and relocating individuals in these age classes. I demonstrated that injection of passive integrated transponders (PIT's) can safely be used as a marking method in young Texas horned lizards. Thirty-two captive bred hatchling lizards were …

Mortality Of An American Marten From An Off-Highway Vehicle, Joshua B. Smith, Jonathan A. Jenks
The Prairie Naturalist
While there are several reviews of the effects of OHVs and recreational activity on wildlife populations (Knight and Gutzwiller 1995, Joslin and Youmans 1999), most studies have focused on physiological (Creel et al. 2002) or behavioral (Van Dyke et al. 1986, Riley et al. 2003) responses to disturbance; none have addressed the potential for direct mortality. In 2005, we documented the death from an OHV of a juvenile, female American marten (F299) that had been radiocollared during a study documenting the distribution and abundance of American marten in the Black Hills, South Dakota (Smith 2007); the Institutional Animal Care and …
Floristic Records In The Platte And Loup River Bottomlands Of Platte County, Nebraska, Michael P. Gutzmer, Robert B. Kaul
Floristic Records In The Platte And Loup River Bottomlands Of Platte County, Nebraska, Michael P. Gutzmer, Robert B. Kaul
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
A recent inventory of vascular plants in the Loup and Platte riverbottoms in Platte County has greatly increased knowledge of the area's flora. Of the 542 species of vascular plants now known to grow in the county, 289 were discovered after 1977, with more than 100 of those after 1990. 425 native and 117 naturalized species are known so far. Nearly 700 native and naturalized alien species are expected to occur in the county, based upon totals from nearby counties. Thus, almost 150 years after European settlement, more than 20% of the species remain unverified; of those, many are undoubtedly …

Arkansas Endemic Biota: An Update With Additions And Deletions, H. Robison, C. Mcallister, C. Carlton, G. Tucker
Journal of the Arkansas Academy of Science
It has been over a decade since the publication of Robison and Allen (1995) that provided the definitive list of endemic flora and fauna of Arkansas. The present study brings up-to-date the endemic biota of the state. Since 1995, several new species have been described and new discoveries have been made, adding species to the state biota. Other species are deleted and new distributional information on other state endemics is presented. Specifically, 3 new plant species are added to the state list while 4 plant species are deleted. Sixteen new animal species/subspecies are added to the state list while numerous …

Investigation Of Kalanchoe Homeobox 1 (Kh1) Gene In Apical Meristems Of Kalanchoe Pinnatum, Jessica Lynn Kirkpatrick
Undergraduate Honors Thesis Collection
Kalanchoe pinnatum (syn. Bryophyllum pinnatum) is a succulent plant that is notable for developing small plantlets on the outer edges of its leaves, when its leaves are detached (Kulka 2006). These plantlets eventually drop off and root, which is a unique way for the plant to asexually reproduce. In most other plants, leaves exhibit determinate growth, meaning once they reach their maturity, they do not continue to grow.

The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari
The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari
Turkish Journal of Botany
Although ultraviolet radiation is potentially harmful, it is an important component of terrestrial radiation to which plants have been exposed since invading land. Since then, plants have evolved mechanisms to avoid and repair UV radiation damage. Therefore, it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. Most of the compounds accumulated are directly involved in UV-B and UV-C protection: they are either efficient in filtering excess radiation or in scavenging radicals. In this study plants were grown for 5 weeks in controlled environment room. The plants were grown in …

Desert Rocks – A Habitat Which Supports Many Species That Were New To Science In The Last 40 Years, Avinoam Danin
Turkish Journal of Botany
Hard limestone, dolomite, sandstone, and granite constitute, under certain conditions, smooth-faced outcrops in desert areas of SW Asia. This habitat supports the most rare plant species in the desert including most of the desert endemics of Israel, Sinai, and Jordan. The smooth-faced outcrops efficiently contribute runoff water to the rock crevices and events when water is available for plant utilisation take place at a higher frequency than in the other habitats in the desert. In many sites plants are isolated and protected by impermeable rocks from competition from other plants. The rare and special plants found in this habitat include …
Mycota Of South-West Asia, Stephan Helfer
Mycota Of South-West Asia, Stephan Helfer
Turkish Journal of Botany
Fungi are indispensable components of the biota of any region. Their presence and distribution are of paramount importance to flora and fauna, and their ecological function may be responsible for the presence or absence of many other species, particularly plants. Database records on fungi from South-West Asia were consulted to estimate the completeness of mycological exploration of the region. Unsurprisingly, some groups are well represented in certain areas, whereas others are lacking from SW Asian data altogether. In this paper an attempt is made to prioritise both taxonomic and geographical focal points in order to maximise the use of resources …

Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen
Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
To maximize rice quality, it is essential to quantify the various factors that affect milling properties of rice. Rice aging, a process during which rice undergoes a series of chemical and physicochemical changes, affects head rice yield (HRY) and the rate at which HRY changes with degree of milling (DOM). This study examined effects of storage duration (0, 2, and 4 months) and storage temperature (4, 21, and 35°C) on milling properties of ‘Wells’ (long-grain) and ‘Jupiter’ (medium-grain) rice cultivars. In general, HRY increased with storage duration, most significantly for Wells cultivar. Millability curves were developed by plotting HRY vs. …

The Effect Of Austrian Winter-Pea Cover Crop And Cow-Pea Companion Crop On Corn Yield, Matthew Marsh, David Longer, Vaughn Skinner
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Leguminous cover crops have the potential to combat the rising input cost of commercial nitrogen (N) fertilizers. This experiment examines benefits of implementing a leguminous cover and/or companion crop into a corn production system. Legumes biologically fix nitrogen from the atmosphere, adding to the nitrogen content of the soil. In this experiment Austrian winter peas (Pisum arvense) (AWP) were used as the leguminous cover crop and cowpeas (Vigna unguiculata) were used as the companion crop. A two year experiment was carried out in which winter peas were planted on half the field in the fall and allowed to grow until …

Investigating The Utilization Of Silica Gel Packets In Drying Research-Scale Rough Rice Samples, Ashley Wiedower, George Ondier, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Rice moisture content (MC) must be reduced to approximately 12.5% MC to prevent spoilage during storage. Desiccants may provide an improved method for drying research-scale rice samples. This study investigated the effects of 1) rice mass to be dried, 2) placement method of silica gel packets in rice samples, 3) regeneration and re-use of the packets, 4) drying temperature, and 5) initial MC on the effectiveness of silica gel packets to dry rough rice samples to the desired 12.5% MC. Multiple masses (200, 500, and 1000 g) of long-grain rice samples were dried using three desiccant placement treatments: 1) intimate …

Floristic Diversity, Conservation Status And Economic Value Of Miniature Sacred Groves In Kanyakumari District, Tamil Nadu, Southern Peninsular India, Selvamony Sukumaran, Solomon Jeeva, Appavoo Deva Sobhana Raj, Doraipandian Kannan
Turkish Journal of Botany
The plant diversity of southern peninsular India has recently been reduced to a great extent due to anthropogenic disturbance and environmental degradation. Disturbance was the major factor responsible for fragmentation of forest vegetation; as a result of this, there is a preponderance of small patches, some of them still preserved as sacred groves because of strong religious beliefs held by the indigenous people of this region. It is thought that one of the prime utilities of sacred groves is the protection and occasional supply of medicinal plants on a sustainable basis. Most of the medicinal plants were confined to these …
