Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson 2016 University of California, Davis

Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson

Michael Johnson

We determined home-range overlap among northern flying squirrels (Glaucomys sabrinus) to assess their spatial organization. We found extensive home-range overlap among females, and though this overlap could reflect social behavior, we found no evidence of attraction among females, with only one instance of den-sharing. Instead, our results suggest that females share foraging areas but may be territorial in portions of the home range, especially around den trees and during young-rearing. Home-range overlap could also result from the extrinsic effect of forest fragmentation due to timber harvest, which might impede dispersal and force squirrels to cluster on remaining fragments of suitable ...

Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo 2016 California Polytechnic State University - San Luis Obispo

Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo

STAR (STEM Teacher and Researcher) Presentations

Abstract: Serpentine soils are formed from ultramafic rocks and are represent an extreme environment for plants. Serpentine soils are unique in that they carry high concentrations of heavy metals, are nutrient deficient, particularly in calcium, and have poor water retention capabilities. Although these soils constitute harsh conditions for plant growth, there are a number of species that are adapted and even endemic to serpentine soil. Water retention by commercial potting mix was compared with serpentine soil. Also, serpentine adapted and non-adapted species were grown in both soil treatments and physiological data were collected. We used the Arduino electronic platform to ...


Impacts Of Fog Drip On Survivorship And Growth Of Native Herb And Shrub Seedlings On Santa Rosa Island, Julianne Bradbury, Ken Niessen, Kathryn McEachern 2016 CSU Channel Islands

Impacts Of Fog Drip On Survivorship And Growth Of Native Herb And Shrub Seedlings On Santa Rosa Island, Julianne Bradbury, Ken Niessen, Kathryn Mceachern

STAR (STEM Teacher and Researcher) Presentations

Overgrazing on Santa Rosa Island led to loss of topsoil in ridgeline groves of endemic island oaks (Quercus tomentella). Restoration specialists attempting to mitigate the impacts of wind and water erosion must determine efficient methods of reestablishing native vegetation. Planting pillows, burlap sacks filled with planting mix and attached to the bedrock substrate, may nurture seedlings long enough for their roots to penetrate the underlying sandstone. Since the island’s ridgeline habitat is often inaccessible during the rainy season, restoration efforts are largely confined to the dry summer months, during which condensed fog is an important source of moisture for ...


The Floral Charms Of Saint John’S: A Survey Of Botanical Communities, Stephen G. Saupe, Paul Melchior 2016 College of Saint Benedict/Saint John's University

The Floral Charms Of Saint John’S: A Survey Of Botanical Communities, Stephen G. Saupe, Paul Melchior

Headwaters: The Faculty Journal of the College of Saint Benedict and Saint John’s University

Saint John’s is a “landscape paradise” in central Minnesota. Although no complete checklist of vegetation exists for the campus, various surveys reveal a diverse flora. This floral wealth is the result of several terrestrial biomes converging on campus — prairie, savanna, deciduous forest, and coniferous forest — as well as diverse aquatic habitats including both lakes and wetlands. A 56-acre restored prairie at the entrance of Saint John’s is dominated by big bluestem and little bluestem. A savanna has been restored to the north and east of the Gemini Lakes and is characterized by bur oaks scattered among prairie grasses ...


Coevolution Of Cyanogenic Bamboos And Bamboo Lemurs On Madagascar, Daniel J. Ballhorn, Fanny Patrika Rakotoarivelo, Stefanie Kautz 2016 Portland State University

Coevolution Of Cyanogenic Bamboos And Bamboo Lemurs On Madagascar, Daniel J. Ballhorn, Fanny Patrika Rakotoarivelo, Stefanie Kautz

Biology Faculty Publications and Presentations

Feeding strategies of specialist herbivores often originate from the coevolutionary arms race of plant defenses and counter-adaptations of herbivores. The interaction between bamboo lemurs and cyanogenic bamboos on Madagascar represents a unique system to study diffuse coevolutionary processes between mammalian herbivores and plant defenses. Bamboo lemurs have different degrees of dietary specialization while bamboos show different levels of chemical defense. In this study, we found variation in cyanogenic potential (HCNp) and nutritive characteristics among five sympatric bamboo species in the Ranomafana area, southeastern Madagascar. The HCNp ranged from 209±72 μmol cyanide* g-1 dwt in Cathariostachys madagascariensis to no ...


Habitat Temperature And Precipitation Of Arabidopsis Thaliana Ecotypes Determine The Response Of Foliar Vasculature, Photosynthesis, And Transpiration To Growth Temperature, William W.

Habitat Temperature And Precipitation Of Arabidopsis Thaliana Ecotypes Determine The Response Of Foliar Vasculature, Photosynthesis, And Transpiration To Growth Temperature, William W. Adams Iii, Jared J. Stewart, Christopher M. Cohu, Onno Muller, Barbara Demmig-Adams

Ecology & Evolutionary Biology Faculty Contributions

Acclimatory adjustments of foliar vascular architecture, photosynthetic capacity, and transpiration rate in Arabidopsis thaliana ecotypes (Italian, Polish [Col-0], Swedish) were characterized in the context of habitat of origin. Temperatures of the habitat of origin decreased linearly with increasing habitat latitude, but habitat precipitation was greatest in Italy, lowest in Poland, and intermediate in Sweden. Plants of the three ecotypes raised under three different growth temperature regimes (low, moderate, and high) exhibited highest photosynthetic capacities, greatest leaf thickness, highest chlorophyll a/b ratio and levels of β-carotene, and greatest levels of wall ingrowths in phloem transfer cells, and, in the Col-0 ...

A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. Th e checklist has far reaching implications and applications, including providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps in our understanding of ...


Endless Symbioses Most Intricate, W. John Hayden 2016 University of Richmond

Endless Symbioses Most Intricate, W. John Hayden

Biology Faculty Publications

Orchids, such as our Wildflower of the Year for 2016, Downy Rattlesnake Plantain (Goodyera pubescens) (Fig. 1), exemplify the interconnectedness of life on Earth. As would be the case for many kinds of plants, pollination comes readily to mind as a prominent example of mutualistic symbiosis. Downy Rattlesnake Plantain is pollinated by bumblebees and other native bees. The bees gain nectar and the orchid gets an efficient means to move pollen from one flower to another; each organism gains benefit from the interaction, the very definition of mutualism. Pollination by bees is widespread among the orchids, but there can be ...

Nishanta Rajakaruna

The increase in usage of heavy metals in different industrial activities causes their existence in effluents. Excessive concentrations of these heavy metals pollute soil and water. Heavy metals cause toxicities and other harmful effects not only in humans and animals but also in plants and soil microorganisms. Heavy metals disrupt many biochemical and physiological activities in bacteria, including growth, development, enzyme and hormone production. Indole acetic acid (IAA) is one of the most important hormones in plants, which is secreted by both bacteria and plants. The present study assessed the effects of Ni, Pb and Cu on the growth of ...


Evolutionary Ecology Of Weeds, 1st & 2nd Editions, Jack Dekker 2016 Retired: Iowa State University-University of Guelph-Michigan State University

Evolutionary Ecology Of Weeds, 1st & 2nd Editions, Jack Dekker

Jack Dekker

2nd Edition, July 2016.  Evolutionary Ecology of Weeds is the story of WHAT, WHY and HOW some plant species invade and occupy habitats ripe for exploitation.  The nature of weeds is the evolution of adaptive traits for seizing and exploiting locally available opportunity.  Weeds are the consequence of human disturbance which creates opportunity spacetime, leaving unused resources eager for invasion by weeds.  The nature of weeds is the story of us, humans.  We created highly successful wild-crop-weed complexes that resist control.  We created them by channeling natural selection, the driver of biological change.  Plants invade by dispersing, colonizing, reproducing and ...


Per Axel Rydberg’S Botanical Collecting Trips To Western Nebraska In 1890 And 1891, Robert B. Kaul, David M. Sutherland 2016 University of Nebraska-Lincoln

Per Axel Rydberg’S Botanical Collecting Trips To Western Nebraska In 1890 And 1891, Robert B. Kaul, David M. Sutherland

Zea E-Books

In the summer of 1891, Per Axel Rydberg and his assistant, Julius Hjalmar Flodman, collected plants in western Nebraska for the United States Department of Agriculture. They collected many first-records for Nebraska as well as some that became type specimens of Rydberg’s and other botanists’ names. In the following autumn and winter, Rydberg made a detailed, typewritten, carbon copied 35-page Report and 37-page List of specimens from that trip; one carbon copy is in the Bessey Herbarium (NEB) at the University of Nebraska–Lincoln. It is these documents that we present here, extensively annotated with our geographic clarifications, original ...


Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius 2016 Augustana College - Rock Island

Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius

Celebration of Learning

Morel mushrooms, Morechella esculenta and M. deliciosa, are known delicacies across the globe, ranging from exquisite dishes in French cuisine to Eastern palates such as Japanese Matsutake. According to literature, true morels diverged as their own genus about 129 million years, again which has led to the development of more than 177 species and have been part of the human diet since their beginning. However, the elusiveness of morels has contributed to the mushrooms infamy for rarity, and has even been known to sell for more than $40 per pound. This project seeks to aid in the search for morels ...

Celebration of Learning

Wisconsin Fast Plant (Brassica Rapa, Brassicaceae) seeds were planted in three six-celled planting chambers. The chambers were filled with standard potting soil under continuous grow-lux lighting. A week after germination, one planting chamber (E1) was supplied with the recommended Miracle-Gro fertilizer solution. Our second experimental chamber (E2) was supplied with 1.5x the eight was 60.4. Our t-tests showed that the height of the control plants vs. E1 was significant (P=.010563), for control plants vs. E2 it was even more significant (P=.008813). However, for E1 vs. E2, our data was insignificant (P=.318883). Our hypothesis was that ...

Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson 2016 California Polytechnic State University - San Luis Obispo

Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson

Master's Theses and Project Reports

It is widely accepted that allelopathy is not only significant, but more or less singular, in the inhibition of understory vegetation in California Eucalyptus globulus (blue gum) plantations. However, there is no published documentation of allelopathy by blue gums against California native species. Here, we present evidence that germination and early seedling growth of five California native species are not inhibited by chemical extracts of blue gum foliage, either at naturally-occurring or artificially concentrated levels. In the greenhouse, seeds were germinated in field-collected soil from mature blue gum plantations and the adjacent native, coastal scrub communities. In petri plates, seeds ...
