Effects Of Elevated Co2 And Nutrients On The Community Metabolism Of A Cymodocea Nodosa Bed, Faisal Khan, Ana Alexandre, Hadayet Ullah, Rui Santos Jan 2016

Effects Of Elevated Co2 And Nutrients On The Community Metabolism Of A Cymodocea Nodosa Bed, Faisal Khan, Ana Alexandre, Hadayet Ullah, Rui Santos

Turkish Journal of Botany

We assessed the combined effects of elevated CO2 and nutrients on the metabolism of a benthic community dominated by the seagrass Cymodocea nodosa (Ucria) Ascherson in a mesocosm experiment. C. Nodosa plants and their associated community were exposed to two CO2 levels simulating future (700 ppm, pH 7.84) and current (360 ppm, pH 8.12) conditions, and two nutrient levels (enriched and ambient concentration) in a total of four treatments (-C-N, -C+N, +C-N, +C+N). Net community production (NCP) was estimated from changes in the concentration of dissolved inorganic carbon in the seawater in light incubations using benthic chambers. The variation pattern …

Turkish Journal of Botany

In a literature search, the presence of Haematococcus in phytoplankton communities and its biogeography were investigated. Haematococcus, although showing a wide biogeographical distribution, has been rarely found in phytoplankton communities. Simultaneously, the colonization potential of air-dispersed Haematococcus in ephemeral waters and its interactions with coexisting phytoplankton taxa were examined by microscopy and molecular methods. Haematococcus was a successful colonist, appearing among the first taxa in the experimental containers. According to principal component analysis, Haematococcus growth rate was negatively correlated with the abundance and species richness of the other autotrophs. Furthermore, a negative correlation between Haematococcus and Chlamydomonas and a positive …

Turkish Journal of Botany

Eumusae leaf spot disease, caused by Mycosphaerella eumusae, is widely distributed in different banana growing countries in Asia and Africa, causing severe losses in yield and quality of banana. The aim of this study was to identify the differentially expressed defense responsive genes through subtractive suppression hybridization (SSH) in the Musa-M. eumusae interaction system. In this method, leaf samples collected at different intervals between 0 and 72 h postinoculation (hpi) of M. eumusae from resistant (Manoranjitham-AAA) and susceptible (Grand Naine-AAA) cultivars were subjected to cDNA-SSH library construction. From the SSH library, 832 clones having the insert were selected and sequenced. …

Phylogenetic Relationships Among Native Oxytropis Species In Turkey Using The Trnl Intron, Trnl-F Igs, And Trnv Intron Cpdna Regions, Ayten Tekpinar, Seher Karaman Erkul, Zeki̇ Aytaç, Zeki̇ Kaya

Turkish Journal of Botany

We tested the phylogenetic utility of three chloroplast DNA loci, i.e. the trnL(UAA) intron, trnL(UAA)-F(GAA) intergenic spacer (IGS), and trnV(UAC) intron, across thirteen native Oxytropis species. Our objective was to determine whether any of these chloroplast DNA markers could be beneficial to figure out phylogenetic relationships among Oxytropis species. To increase the interspecific sampling, nine sequences of the trnL intron and trnL-F regions were retrieved from GenBank and included in the analyses. No sequence of the trnV intron region was available in the database and so only sequences of the native species were used for the analyses. Phylogenies derived from …

What Would The Babel Fish Say?, Monica Gagliano Jan 2016

What Would The Babel Fish Say?, Monica Gagliano

Animal Sentience

Starting with its title, Key’s (2016) target article advocates the view that fish do not feel pain. The author describes the neuroanatomical, physiological and behavioural conditions involved in the experience of pain in humans and rodents and confidently applies analogical arguments as though they were established facts in support of the negative conclusion about the inability of fish to feel pain. The logical reasoning, unfortunately, becomes somewhat incoherent, with the arbitrary application of the designated human criteria for an analogical argument to one animal species (e.g., rodents) but not another (fish). Research findings are reported selectively, and questionable interpretations are …

Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen

Western North American Naturalist

In the northern U.S. Rockies, including the Greater Yellowstone Ecosystem (GYE), connectivity is a concern because large carnivores have difficulties dispersing successfully between protected areas. One area of high conservation value because of its importance for connecting the GYE to wilderness areas of central Idaho is the Centennial Mountains and surrounding valleys (2500 km2) along the Idaho–Montana border just west of Yellowstone National Park. The current expansion of grizzly bears (Ursus arctos) and other large carnivore populations outside protected areas of Yellowstone National Park and Grand Teton National Park has placed a greater emphasis on potential linkage zones …

Extension Agriculture And Natural Resources In The U.S. Midwest: A Review And Analysis Of Challenges And Future Opportunities, Mahdi M. Al-Kaisi, Roger Wesley Elmore, Gerald A. Miller, David Kwaw-Mensah

Department of Agronomy and Horticulture: Faculty Publications

This review addresses key changes in U.S. agricultural extension and future opportunities. Agricultural extension has been a part of the land-grant university (LGU) system for more than 100 years. The Morrill Act of 1862 established the LGU system by authorizing states access to federally controlled land and funding for public institutions offering educational opportunities focusing on agriculture and mechanical arts for farmers and the working class. Current surveys in Iowa reveal changing trends in extension: more than 90% of farmers identified private-sector crop advisers as their primary source for recommendations, whereas more than 80% of those advisors identified Iowa State …

Restoration Of A Wet Longleaf Pine (Pinus Palustris) Savanna In Southeast Louisiana: Burning Toward Reference Conditions, Alex K. Entrup

LSU New Orleans Theses and Dissertations

This study quantifies the changes in vegetation composition and structure of a fire-excluded Pinus palustris (longleaf pine) wetland savanna restoration site in southeastern in comparison to a proximate contemporary reference site. The restoration site was invaded by hardwood species and off-site pines, and never underwent extensive soil disturbance. The restoration treatments involved logging across portions of the site and the reintroduction of fire across the entire site. All species present in 10m2 quadrats were recorded prior to treatment and throughout the 17 year study at reference and treatment sites. The community composition of both logged and unlogged sites converged …
