Comparative Vegetative Anatomy And Systematics Of Oncidiinae (Maxillarieae, Orchidaceae), William Stern, Barbara Carlsward

Faculty Research & Creative Activity

Subtribe Oncidiinae comprises a vegetatively heterogeneous assemblage of species that has persistently been incapable of organization. Anatomy was considered to be a possible means to resolve the perplexity of relationships amongst the constituent taxa. The consistent occurrence of a foliar hypodermis, homogeneous mesophyll, conical silica bodies in stegmata, and ubiquitous fibre bundles in leaves provides a matrix for linking the taxa, as do the parenchymatous pith and O-thickened endodermal cell walls in roots. However, the strict consensus of the 40 genera studied was completely unresolved, suggesting that vegetative characters alone are insufficient to assess the relationships amongst these taxa, a …

Flora And Vegetation Of Coneflower Glacial Drift Hill Prairie Natural Area, Moultrie County, Illinois, Gordon Tucker, Nicholas Owens, John Ebinger

Faculty Research & Creative Activity

The vascular flora of Coneflower Glacial Drift Hill Prairie Natural Area in Moultrie County, east-central Illinois, was studied during the growing seasons of 2002 and 2003. The prairie is located on a steep SW-facing hillside of the Cerro Gordo Glacial Moraine, overlooking the Kaskaskia River Valley and Lake Shelbyville. The flora was documented by general reconnaissance, and the structure of the vegetation was sampled in September 2003 using 0.25 m2 plots placed along two transects. The site supported 164 vascular plant species (including one named hybrid). The native grasses with the highest importance values were Andropogon gerardii (big bluestem) and …

Fungal Spore Dispersal By The Eastern Box Turtle (Terrapene Carolina Carolina), S. Jones, W. Jordan, Scott Meiners, A. Miller, A. Methven

Faculty Research & Creative Activity

Although spores from most macrofungi are wind- or water-dispersed, dispersal may also occur via biotic vectors. The Eastern box turtle (Terrapene carolina carolina) is a facultative mycovore that may play an important role in fungal spore dispersal although, to date, no information exists on fungi occurring in fecal samples of box turtles or on the ecological significance of box turtles as spore dispersal vectors. Consequently, a study of the potential for Eastern box turtles to act as vectors for spore dispersal was initiated by capturing wild turtles and collecting fecal samples. Serial dilutions from fecal samples were made to enumerate …

How Just Is The Union's Area Of Freedom, Security And Justice?:An Assessment Of The Normative Status Of International Fundamental Rights In The Union's Legal Order., Stephen Carruthers

Other resources

This thesis argues that international fundamental rights provide the most appropriate measure of justice for the Union’s area of ‘freedom, security and justice’ (AFSJ). However, it is argued that the normative status of international fundamental rights in Union law is undermined by the pursuit of the objective of autonomy of Union law and deficiencies in the legal mechanisms for giving effect to those rights.

This research analyses the sources and normative status of international fundamental rights in Union law, and in particular the AFSJ, both as currently constituted and under the Constitution, and assesses the robustness and effectiveness of the …

Eastern Bluebirds Eject Brown-Headed Cowbird Eggs, Brian D. Peer, Lyndon R. Hawkins, Edwin P. Steinke, Patricia Blair Bollinger, Eric K. Bollinger

Faculty Research & Creative Activity

The relationship between the Brownheaded Cowbird (Molothrus ater) and its cavitynesting hosts has received little attention because of the assumption that cowbirds rarely parasitize these hosts. We tested the Eastern Bluebird (Sialia sialis), a host that is sometimes heavily parasitized by cowbirds, for egg ejection behavior. Bluebirds ejected 65% of experimentally added cowbird eggs (n = 20), but ejected no experimentally added conspecific eggs (n = 66). This suggests that cowbird parasitism, not conspecific brood parasitism, is the selective pressure responsible for egg ejection in this species. This level of rejection may be conservative because bluebirds nest in dark cavities, …

The Ethics Of Wildlife Control In Humanized Landscapes, John Hadidian, Camilla H. Fox, William S. Lynn

Ecology Collection

The 21st century is witness to an unprecedented and rapid growth of human settlements, from urban centers to wilderness vacation resorts. Concurrent with this has been the growing tolerance and acceptance of many wild animals and humans for one another. This has created an expanding ‘zone’ of human-animal contacts, some number of which invariably result in conflicts. While the vast majority of our interactions with wild animals are undoubtedly benign, it is the conflict between wildlife and people that draws particularly close attention from the public. Animals viewed as vertebrate “pests” range from the small to the large, the timid …

Ethics And Welfare: Pain Perception In Fish, L. U. Sneddon

Aquaculture Collection

Fish welfare is currently a controversial subject with many scientific studies now demonstrating the possibility for fish to experience negative events such as pain, fear and stress. This has important implications in the treatment of fish during commercial and experimental procedures in terms of ethics and welfare. In this review, the evidence for pain perception in fish is considered and the repercussions for the use of fish as a research model as well as in aquaculture and largescale fisheries. These issues are discussed briefly from a welfare and ethical perspective.

Forty-Two Thousand And One Dalmatians: Fads, Social Contagion, And Dog Breed Popularity, Harold A. Herzog

Pets Collection

Like other cultural variants, tastes in companion animals (pets) can shift rapidly. An analysis of American Kennel Club puppy registrations from 1946 through 2003 (N = 48,598,233 puppy registrations) identified rapid but transient large-scale increases in the popularity of specific dog breeds. Nine breeds of dogs showed particularly pronounced booms and busts in popularity. On average, the increase (boom) phase in these breeds lasted 14 years, during which time annual new registrations increased 3,200%. Equally steep decreases in registrations for the breeds immediately followed these jumps in popularity. The existence of extreme fluctuations in preferences for dog breeds has implications …

Exploration And Habituation In Intact Free Moving Octopus Vulgaris, Jennifer Mather

Sentience Collection

Despite the huge numbers of studies published on the learning of cephalopod mollusks, studies on non-associative learning are scarce. We tested non-associative learning (habituation) and exploration in Octopus vulgaris in two different studies using a prey-shaped object (Study A) and inanimate objects and food objects (Study B). Study A consisted of the repeated presentation of a prey-like stimulus, which 23 subjects could only explore visually. In study B, 14 octopuses were presented two Lego blocks (one black and white with a smooth surface, one a blue "snowflake" with a rough surface) and two food items, one preferred (clams) and one …

The Effect Of Housing And Handling Practices On The Welfare, Behaviour And Selection Of Domestic Cats (Felis Sylvestris Catus) By Adopters In An Animal Shelter, N. Gourkow, D. Fraser

Shelter Management and Adoption Procedures Collection

As adult cats can often be difficult to re-home, they may spend long periods in rescue shelters where barren housing and inconsistent handling can reduce their welfare. In this study, 165 adult cats in an animal shelter in Vancouver, Canada, were assigned to four treatments. The Basic Single treatment reflected typical conditions in that particular shelter, with cats handled in an inconsistent manner by various staff and housed singly in relatively barren cages. Three alternative treatments involved more consistent, positive handling by only the experimenter and research assistants, plus three housing conditions: Enriched Single (individual cages with opportunities to perch …

Differential Effects Of Sodium And Magnesium Sulfate On Water Consumption By Beef Cattle, A. S. Grout, D. M. Veira, D. M. Weary, M. A. G. Von Keyserlingk, D. Fraser

Biochemistry Collection

The existing guidelines for maximum sulfate (SO₄) in cattle drinking water are based on Na2SO₄, although many water sources contain greater concentrations of MgSO₄. Two experiments compared the effect of different SO₄ salts on water consumption and fecal DM of cattle. In Exp. 1, 8 yearling heifers (initial BW = 345 ± 8 kg; mean ± SD) were watered twice daily with tapwater or water containing Na₂SO₄ or MgSO₄ at target levels of 1,500, 3,000, or 4,500 mg of SO₄/L for 2-d treatment periods separated by 2 …

Early Ontogenetic Diet In Gray Wolves, Canis Lupus, Of Coastal British Columbia, Heather M. Bryan, Chris T. Darimont, Thomas E. Reimchen, Paul C. Paquet

Biogeography and Ecological Opportunity Collection

Within populations, different age classes often consume dissimilar resources, and provisioning of juveniles by adults is one mechanism by which this can occur. Although the diet of Gray Wolves (Canis lupus) has been studied extensively, the diet of pups is largely unknown. We examined faeces deposited by altricial pups and adult providers during the first two months following birth at two den sites over two years on the central coast of British Columbia, Canada. Pups and adult wolves consumed similar species, and Black-tailed Deer (Odocoileus hemionus) constituted most of the diet for both age groups. Pup and adult diet, however, …

The two main routes, legislation and education, are examined first, followed by practical advice on how to campaign, lobby and use the media to your benefit. Part 3 …

Behaviour Development: A Cephalopod Perspective, Jennifer A. Mather

Interactive Behavior Collection

This paper evaluates the development of behaviour from the viewpoint of the intelligent and learningdependent cephalopod mollusks as a contrast to that of mammals. They have a short lifespan, commonly one to two years, and most are semelparous, reproducing only near the end of their lifespan. In the first two months of life, Sepia officinalis cuttlefish show drastic limitation on learning of prey choice and capture, gradually acquiring first short-term and then long-term learning over 60 days. This is paralleled by development of the vertical lobe of the brain which processes visually learned information. In the long nonreproductive adulthood, Octopus …

“Nuisance” Wildlife Control Trapping: Another Perspective, Brad Gates, John Hadidian, Laura Simon

Wildlife Population Management Collection

Urban wildlife control is a rapidly growing profession in which many practitioners apparently still come from a recreational or commercial trapping background. Perhaps for that reason, much of the “control” in resolving human-wildlife conflicts in cities and suburbs seems to revolve around the use of lethal traps to eliminate “problem” animals. Although some states allow relocation and most apparently allow for nuisance animals to be released on site, the extent to which these practices occur is little known. Further, the biological impacts of continual trapping cycles on urban wildlife populations remain little known as well. An alternative approach to trapping …

Profile: Why Write?, University Relations

Profile (1996-)

We have been doing some careful strategic thinking about UMM's future during the past months. The entire University of Minnesota system has been working on a strategic plan, as has our campus, and, in addition, we are searching for a new chancellor. I find it strange, and unexpected, that as an impending retiree I'm thinking so much about what is to come, and so little about what has been!

Biomass Dynamics Of Tipula (Insecta: Diptera) In Forested Streams Of The Interior Highlands, Arkansas, Samuel B. Mccord, Alan D. Christian, Richard S. Grippo

Journal of the Arkansas Academy of Science

Abundance patterns of aquatic macroinvertebrates that utilize coarse particulate organic matter as a food source are important indicators of non--point source pollution associated with silviculture activities. This group, referred to as shredders, typically decreases in abundance as its food source—primarily leaves—is removed from the ecosystem. We tested whether larval biomass of the crane fly Tipula, a common member of the group, was an effective estimator of shredder abundance. Additionally, we used regression analysis to test whether the length to dry mass relationship of Tipula differed among geographic regions, between seasons, and between years. Results did not indicate significant differences in …

Status Survey Of The Peppered Shiner, Notropis Perpallidus Hubbs And Black, In Arkansas And Oklahoma, Henry W. Robison

Journal of the Arkansas Academy of Science

The peppered shiner, Notropis perpallidus Hubbs and Black, is a small, silvery, upland stream fish found only in southwestern Arkansas and eastern Oklahoma. This fish species was studied from 1999-2001 to determine its distribution, habitat, and conservation status. A total of81 collections was made during the 2-year study; however, only 17 specimens were collected. The present distribution of the peppered shiner in Arkansas and Oklahoma is described as well as the conservation status of this cyprinid in both states.
