Plasma Testosterone Correlates With Morph Type Across Breeding Substages In Male White-Throated Sparrows, M. B. Swett, Creagh W. Breuner

Biological Sciences Faculty Publications

White-throated sparrows (Zonotrichia albicollis) exhibit a genetic polymorphism that affects plumage and behavior in both sexes. White-striped morphs are more territorially aggressive, whereas tan-striped morphs provision nestlings at a higher rate. We investigated testosterone physiology in this species in an effort to understand hormonal mechanisms for the observed differences in aggression and parental care between the morphs. We found a small but significant difference in plasma testosterone between free-living white-striped and tan-striped males over the course of the breeding season. This difference correlates with previously observed differences in aggressive behavior and suggests that testosterone may mediate these differences. Testosterone remained …

Pestilence, Persistence And Pathogenicity: Infection Strategies Of Bartonella, Michael F. Minnick, James M. Battisti

Biological Sciences Faculty Publications

It has been nearly two decades since the discovery of Bartonella as an agent of bacillary angiomatosis in AIDS patients and persistent bacteremia and 'nonculturable' endocarditis in homeless people. Since that time, the number of Bartonella species identified has increased from one to 24, and 10 of these bacteria are associated with human disease. Although Bartonella is the only genus that infects human erythrocytes and triggers pathological angiogenesis in the vascular bed, the group remains understudied compared with most other bacterial pathogens. Numerous questions regarding Bartonella's molecular pathogenesis and epidemiology remain unanswered. Virtually every mammal harbors one or more Bartonella …

Tri-Trophic Linkages In Disease: Pathogen Transmission To Rainbow Trout Through Stonefly Prey, Sandra M. Adams, Aaron S. Adams, William E. Holben

Biological Sciences Faculty Publications

ABSTRACT Relationships between macroinvertebrates and microorganisms in aquatic environments are only poorly understood despite the fact that many aquatic macroinvertebrates feed on microbial biofilms during some life stage. Better understanding of trophic interactions between microbial biofims, macroinvertebrates, and fish may also help control fish diseases and loss of natural resources. It has also been suggested that pollution, habitat fragmentation, and poor water quality may contribute to increased pathogenesis and mortality in fish. Increased disease incidence is difficult to assess, however, in part because of the complexity of pathogen transmission dynamics. Several environmental pathogens exist whose reservoir(s) and means of transmission …

Neglect Of Genetic Diversity In Implementation Of The Convention On Biological Diversity, Linda Laikre, Fred W. Allendorf, Laurel C. Aroner, C. Scott Baker, David P. Gregovich, Michael M.

Wildlife Biology Faculty Publications

Genetic diversity is the foundation for all biological diversity; the persistence and evolutionary potential of species depend on it. World leaders have agreed on the conservation of genetic diversity as an explicit goal of the Convention on Biological Diversity (CBD). Nevertheless, actions to protect genetic diversity are largely lacking. With only months left to the 2010-biodiversity target, when the 191 parties to the CBD have agreed on achieving a significant reduction of the rate of biodiversity loss, gene-level diversity is still not being monitored, and indicators and thresholds that can be used to devise strategies to conserve this important component …

A Continent-Wide Clone: Population Genetic Variation Of The Invasive Plant Hieracium Aurantiacum (Orange Hawkweed; Asteraceae) In North America, Eli S. Loomis, Lila Fishman

Biological Sciences Faculty Publications

We investigated the population genetic structure of the invasive plant Hieracium aurantiacum (Asteraceae), a facultative apomict. We generated amplified fragment length polymorphism fingerprints for H. aurantiacum samples from across its invasive range in North America (N = 226) and from six other North American native and invasive Hieracium species (N = 60). Almost no genetic variability was found in the North American H. aurantiacum across locations from Alaska and Oregon to Pennsylvania and Ontario (clonal diversity = 0.035). In contrast, other Hieracium species showed a range of clonal diversities (range = 0.154-1.0). The single H. aurantiacum genotype that dominated the …

Bar-Coded Pyrosequencing Reveals Shared Bacterial Community Properties Along The Temperature Gradients Of Two Alkaline Hot Springs In Yellowstone National Park, Scott R. Miller, Aaron L. Strong, Kenneter L. Jones, Mark C. Ungerer

Biological Sciences Faculty Publications

An understanding of how communities are organized is a fundamental goal of ecology but one which has historically been elusive for microbial systems. We used a bar-coded pyrosequencing approach targeting the V3 region of the bacterial small-subunit rRNA gene to address the factors that structure communities along the thermal gradients of two alkaline hot springs in the Lower Geyser Basin of Yellowstone National Park. The filtered data set included a total of nearly 34,000 sequences from 39 environmental samples. Each was assigned to one of 391 operational taxonomic units (OTUs) identified by their unique V3 sequence signatures. Although the two …

Graph Isomorphisms And Matrix Similarity: Switching Between Representations, Thierry Dana-Picard

The Mathematics Enthusiast

A proof whether two graphs (possibly oriented graphs or multigraphs, etc.) are isomorphic or not can be derived by various methods. Some of them are reasonable for small numbers of vertices and/or edges, but not for larger numbers. Switching from iconic representation to a matrix representation transforms the problem of Graph Theory into a problem in Linear Algebra. The support provided by a Computer Algebra System is analyzed, in particular with regard to the building of new mathematical knowledge through a transition from graphical to algebraic representation. Moreover two important issues are discussed: a. the need for more than one …

Ontogeny And Individual Variation In The Adrenocortical Response Of Zebra Finch (Taeniopygia Guttata) Nestlings, Haruka Wada, Katrina G. Salvante, Emily Wagner, Tony D. Williams, Creagh W. Breuner

Biological Sciences Faculty Publications

Numerous studies indicate interspecies variation in the ontogeny of the adrenocortical response in birds; however, little is known about the extent of interindividual variation in avian young. Toward this end, we examined the ontogeny and interindividual variation in the adrenocortical response in zebra finch (Taeniopygia guttata) nestlings. We measured baseline and stress-induced total (bound and free) corticosterone, corticosteroid binding globulin capacity, and resulting estimated free corticosterone levels in nestlings of four different ages ( days 5, 10, 16, and 21). In addition, we investigated the potential correlates of interindividual variation (brood size and mass). Nestlings at days 5 and 10 …

Abundance And Density Of Mountain Plover (Charadrius Montanus) And Burrowing Owl (Athene Cunicularia) In Eastern Colorado, Heather C. Tipton, Paul F. Doherty Jr., Victoria J. Dreitz

Wildlife Biology Faculty Publications

Because of continental-scale declines of grassland birds over the past century, conservation agendas are focused on increasing understanding of grassland bird ecology and habitat associations. Shortgrass prairie is a unique grassland ecosystem maintained, in part, by Black-tailed Prairie Dogs (Cynomys ludovicianus). The Mountain Plover (Charadrius montanus) and western Burrowing Owl (Athene cunicularia hypugaea) are species of conservation concern known to be associated with prairie dog colonies. We estimated abundance of Mountain Plovers and Burrowing Owls in three habitats within the Colorado shortgrass prairie ecosystem— prairie dog colonies, grassland not occupied by prairie dogs, and …

Bushmeat Poaching Reduces The Seed Dispersal And Population Growth Rate Of A Mammal-Dispersed Tree, Jedidiah F. Brodie, Olga E. Helmy, Warren Y. Brockelman, John L. Maron

Biological Sciences Faculty Publications

Myriad tropical vertebrates are threatened by overharvest. Whether this harvest has indirect effects on nonhunted organisms that interact with the game species is a critical question. Many tropical birds and mammals disperse seeds. Their overhunting in forests can cause zoochorous trees to suffer from reduced seed dispersal. Yet how these reductions in seed dispersal influence tree abundance and population dynamics remains unclear. Reproductive parameters in long-lived organisms often have very low elasticities; indeed the demographic importance of seed dispersal is an open question. We asked how variation in hunting pressure across four national parks with seasonal forest in northern Thailand …

What Drives Long-Distance Dispersal? A Test Of Theoretical Predictions, Winsor H. Lowe

Biological Sciences Faculty Publications

Long-distance dispersal (LDD) may contribute disproportionately to species persistence in fragmented landscapes, non-native invasions, and range shifts in response to climate change. However, direct data on LDD are extremely limited, leaving us with little understanding of why it occurs. I used six years of mark–recapture data on the stream salamander Gyrinophilus porphyriticus to test theoretical predictions of how variation in habitat quality affects LDD. Frequency of LDD was quantified using the kurtosis of yearly movement distributions from recaptured animals in a 1-km headwater stream. Temporal and spatial variation in habitat quality were quantified with spatially explicit data on the body …

Global Population Dynamics And Hot Spots Of Response To Climate Change, Eric Post, Jebediah Brodie, Mark Hebblewhite, Angela D. Anders, Julie A. K. Maier, Christopher C. Wilmers

Wildlife Biology Faculty Publications

Understanding how biotic and abiotic factors influence the abundance and distribution of organisms has become more important with the growing awareness of the ecological consequences of climate change. In this article, we outline an approach that complements bioclimatic envelope modeling in quantifying the effects of climate change at the species level. The global population dynamics approach, which relies on distribution-wide, data-driven analyses of dynamics, goes beyond quantifying biotic interactions in population dynamics to identify hot spots of response to climate change. Such hot spots highlight populations or locations within species' distributions that are particularly sensitive to climate change, and identification …
