The Effect Of Air Pollution On Microsporogenesis, Pollen Development And Soluble Pollen Proteins In Spartium Junceum L. (Fabaceae), Farkhondeh Rezanejad

Turkish Journal of Botany

Air pollution induces abnormality in anthers, reduction of pollen grains´ umbers and male sterility. Anthers of Spartium junceum L. (Spanish broom) were collected at different stages of development from control (less polluted) and polluted areas (mainly SO_2, NO_2, CO, hydrocarbons (HCs) and airborne particulate material (APM)). Structure and development of anther walls and pollen grains were studied and compared. Groups of the control pollen grains were exposed to the polluted air of Tehran for 10 and 20 days. Under pollution stress some anthers became abnormal and shrunken. The tapetum layer had a precocious growth in the microspore mother cell stage …

Temporal Changes In Environmental Characteristics And Diversity Of Net Phytoplankton In A Freshwater Lake, C. Chattopadhyay, T. C. Banerjee

Turkish Journal of Botany

Temporal changes in the species composition, seasonal abundance, and diversity of net phytoplankton (NPP) were investigated in relation to some environmental characteristics of the water and sediment of Lake Krishnasayer, an ancient man-made shallow freshwater lake, located at Burdwan, India, between January and December 2003. In all, 43 species and 7 genera were identified from the weekly samples taken from a 1 x 1 x 1-m water column at sites I and II. The most abundant taxa were Cyanophyta (34.8%-37.8%) and Bacillariophyta (34.2%-34.3%), whilst Euglenophyta was the least abundant (4%-5.3%). The relationships (r) were significant (P < 0.05) and positive between water temperature and abundance of Euglenophyta, Secchi transparency, and Chlorophyta and Bacillariophyta, dissolved oxygen and Chlorophyta, dissolved chloride, and Cyanophyta and Euglenophyta, phosphate-phosphorus and Cyanophyta, and organic carbon and Bacillariophyta. In contrast, the relationships (r) were significant (P < 0.05), but inverse between water temperature and abundance of Bacillariophyta, Secchi transparency and Euglenophyta, dissolved chloride and Bacillariophyta, nitrate-nitrogen and Euglenophyta, and organic carbon and Euglenophyta. Furthermore, regression coefficients (b) indicated a significant (P < 0.05) positive relationship between Secchi transparency and overall NPP abundance, and a significant (P < 0.05) inverse relationship between silica and overall NPP abundance. The diversity indicated high values with peaks in species abundance in March, May, and September at site I, and in May, September, and November at site II. The seasonal abundance and frequency of occurrence for a few dominant species of Cyanophyta (e.g., Anabaena circinalis, Nostoc carneum, Oscillatoria formosa, Rivularia haematitis, and Spirula subsalsa), Chlorophyta (e.g., Spirogyra communis, Ulothrix tenerrima, and Zygnema pectinum), Euglenophyta (e.g., Euglena viridis), and Bacillariophyta (e.g., Cyclotella glomerata, Navicula capitata, Nitzschia acicularis, and Pinnularia major) in the surface water of this lake were 3.3%-5.5%, respectively.

Germination And Seedling Behaviours Of Seeds Of Peltophorum Pterocarpum D.C.Baker Ex K.Heyne Growing Under Motor Vehicle Emission, Muhammad Shafiq, Muhammad Zafar Iqbal

Turkish Journal of Botany

Motor vehicle emission showed toxic effects on seed germination and seedling growth of Peltophorum pterocarpum D.C.Baker ex K.Heyne. Germination and growth of P. pterocarpum seeds were significantly (P < 0.05) affected in the seeds collected from the polluted areas as compared to the less polluted areas. A higher percentage of decrease in seed germination was found for the seeds collected from the extremely polluted area, followed by very much polluted, polluted, and a little polluted areas as compared to the unpolluted area (control). Seedling and root lengths were also highly decreased for the seeds of the same species collected from the extremely polluted area as compared to the control. A high percentage of seedling dry weight was found for the seeds of the same species collected from the extremely polluted area (62%), followed by very much polluted area (58%), polluted area (38%), and a little polluted area (28%) as compared to the control. According to the tolerance test, seedling growth of P. pterocarpum showed the lowest percentage of tolerance in the samples collected from the extremely polluted area (53%), followed by very much polluted area (71%), polluted area (89%), and a little polluted area (92%) as compared to the campus.

Succession Of An Iowa Sand Prairie Into An Adjoining Old-Field, Susan Jill Kirt

Dissertations and Theses @ UNI

Native plant succession studies were conducted in 2000 and 2001 at the Cedar Hills Sand Prairie northwest of Cedar Falls, IA. The study site consisted of a remnant sand prairie with an adjoining old-field that had been undergoing secondary succession since the mid-1970s. Vegetation was sampled over a 100 m transect of the remnant prairie and a 200 m transect of the old-field. The transect was sub-divided into 50 m subsites to examine progression of native species into the old-field. To analyze changes in vegetation, the similarity of the sub-sites were compared for percent canopy cover and number of species …

The Plant Structure Ontology, A Unified Vocabulary Of Anatomy And Morphology Of A Flowering Plant, Katica Ilic, Elizabeth Kellogg, Pankaj Jaiswal, Felipe Zapata, Peter Stevens, Leszek Vincent, Shulamit Avraham, Leonore Reiser, Anuradha Pujar, Martin Sachs, Noah Whitman, Susan Mccouch, Mary Schaeffer, Doreen Ware, Lincoln Stein, Seung Rhee

Biology Department Faculty Works

Formal description of plant phenotypes and standardized annotation of gene expression and protein localization data require uniform terminology that accurately describes plant anatomy and morphology. This facilitates cross species comparative studies and quantitative comparison of phenotypes and expression patterns. A major drawback is variable terminology that is used to describe plant anatomy and morphology in publications and genomic databases for different species. The same terms are sometimes applied to different plant structures in different taxonomic groups. Conversely, similar structures are named by their species-specific terms. To address this problem, we created the Plant Structure Ontology (PSO), the first generic ontological …

Biomass Estimation And Classification Of Secondary Succession Using Radar And Optical Remote Sensing Data Based On Textural And Spectral Analysis In Amazonia, Ping Jiang

All-Inclusive List of Electronic Theses and Dissertations

Deforestation that happened during past decades in the Amazon Basin has been potentially affecting the global climate and carbon-cycle by contributing a vast amount of carbon into the atmosphere. Above-ground biomass (AGB) estimation of secondary successional and mature forests using remote sensing technology has been attracting scientists' attention. Optical sensor data are sensitive to forest canopies only, and therefore have limitations in AGB estimation, especially for tropical forests with complex structures and abundant species. Radar signals have the ability to penetrate canopies to detect the sub-layers of forests, and therefore potentially have a better performance in AGB estimation. Based on …

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore

The Prairie Naturalist

There have been almost no surveys of herpetofauna at 109 km² Lostwood National Wildlife Refuge (LNWR) or surrounding counties in northwestern North Dakota, an area possibly undergoing significant environmental change from fossil fuel extraction and use. We used 30 m drift fences to survey amphibian and reptile species in prairie-wetland transition zones at LNWR during mid-May to early-July in 1985 to 1987, and again in 1999 and 2000. We captured only four amphibian and two reptilian species and noted one other reptilian species incidental to our survey. Several species expected to occur in the area were not detected.

Plant Reproductive Allocation Predicts Herbivore Dynamics Across Spatial And Temporal Scales, Tom E. X. Miller, Andrew J. Tyre, Svata M. Louda

School of Biological Sciences: Faculty Publications

Life-history theory suggests that iteroparous plants should be flexible in their allocation of resources toward growth and reproduction. Such plasticity could have consequences for herbivores that prefer or specialize on vegetative versus reproductive structures. To test this prediction, we studied the response of the cactus bug (Narnia pallidicornis) to meristem allocation by tree cholla cactus (Opuntia imbricata). We evaluated the explanatory power of demographic models that incorporated variation in cactus relative reproductive effort (RRE; the proportion of meristems allocated toward reproduction). Field data provided strong support for a single model that defined herbivore fecundity as a …

Artificial Burrows And The Deer Mouse: Do Number Of Entrances Influence Use?, Glennis A. Kaufman, Donald W. Kaufman

The Prairie Naturalist

We examined use of artificial burrows by the deer mouse (Peromyscus maniculatus) in mixed grass prairie in north central Kansas. We predicted differential use of burrows, such that the deer mouse would prefer two entrance burrows in non-winter months when predatory snakes were active, but prefer one entrance burrows in winter when cold, windy conditions existed. We installed 20 pairs of artificial burrows (one single entrance and one double entrance) in summer 1988. We examined these burrows on seven dates from autumn 1988 to autumn 1989. All mice (n = 70) used two entrance burrows at least …
