Intertidal Benthic Resources Of The Copper River Delta, Alaska, Usa, Sean Powers, Mary Anne Bishop, Jonathan H. Grabowski, Charles H. Peterson

University Faculty and Staff Publications

The Copper River Delta, Alaska is the largest contiguous coastal wetland system along the West Coast of North America. Vast expanses of tidal mud flats formed by sediments carried by the suspended load of the Copper River serve as a connection between the Gulf of Alaska and the extensive network of wetlands, rivers and sloughs of the delta system. In addition to providing habitat for resident fish, shrimp and crabs, these tidal flats serve as critical feeding grounds for up to 5 million migratory shorebirds as well as an entry and exit corridor for three species of commercially fished salmonids. …

Word Repetition In Danish: "Jeg Mener 'Saeg' Ikke 'Skaeg'" (I Mean 'Funny' Not 'Beard'), Joshua Nash

Word Ways

A notable feature of language is the use of the same word to communicate different meanings. The first example that comes to mind in English is still. I am aware of at least three meanings (1) when something is motionless or at rest, (2) apparatus used to distill alcohol, and (3) the adverb still which means 'as yet' or 'up to this time' (for example, 'are you still there?').

Short-Term And Long-Term Effects Of Vocal Distortion On Song Maintenance In Zebra Finches, Gerald E. Hough, Susan F. Volman

College of Science & Mathematics Departmental Research

Adult zebra finch song is irreversibly altered when birds are deprived of correct feedback by deafening or denervation of the syrinx. To clarify the role of feedback in song maintenance, we developed a reversible technique to distort vocal output without damaging the auditory or vocal systems. We implanted flexible beads adjacent to the syrinx to alter its biomechanics. Immediate song aberrations included low volume, frequency shifts, missing harmonics, and production of click-like syllables. After a few weeks, seven of nine birds stopped producing some syllables. In six of these birds, the gaps left by the silenced syllables gradually shortened, and …

A Biomechanical Comparison Of Three Sternotomy Closure Techniques, David J. Cohen, Lanny V. Griffin

Biomedical Engineering

Background. A biomechanical study of three sternotomy closuretechniques (figure-of-eight stainless-steel wires, PectofixDynamic Sternal Fixation [DSF] stainless-steel plates, and figure-of-eightstainless-steel cables) was conducted to compare strength andstiffness variables in three clinically relevant loading modes(anterior-posterior shear, longitudinal shear, and lateral distraction).

Methods. All tests were conducted on polyurethane foam sternalmodels that simulate the properties of cancellous bone. Eachmodel was divided longitudinally and reconstructed using oneof the sternotomy closure repair techniques. Tests were performedusing a materials testing system that applies a continuouslyincreasing amount of force in one direction to the model untilit catastrophically breaks. A total of six trials of each …

An Ecological And Evolutionary Analysis Of Photosynthetic Thermotolerance Using The Temperature-Dependent Increase In Fluorescence, Charles A. Knight, David D. Ackerly

Biological Sciences

The hypothesis that species inhabiting warmer regions have greater photosynthetic tolerance of high temperatures was tested using the temperature-dependent increase in fluorescence (T-F_o). Congeneric species pairs of Atriplex, Salvia, Encelia, and Eriogonum with desert versus coastal distributions were studied in a common environment and in the field. In addition, 21 species with contrasting microclimate distributions were studied at a field site in a northern California chaparral community. The average July maximum temperature within the current distributions of species was quantified using a geographic information system. Four parameters (T_crit, T_S20, …

Leaf Size, Specific Leaf Area And Microhabitat Distribution Of Chaparral Woody Plants: Contrasting Patterns In Species Level And Community Level Analyses, D. D. Ackerly, Charles A. Knight, S. B. Weiss, K. Barton, K. P. Starmer

Biological Sciences

We examined variation in leaf size and specific leaf area (SLA) in relation to the distribution of 22 chaparral shrub species on small-scale gradients of aspect and elevation. Potential incident solar radiation (insolation) was estimated from a geographic information system to quantify microclimate affinities of these species across north- and south-facing slopes. At the community level, leaf size and SLA both declined with increasing insolation, based on average trait values for the species found in plots along the gradient. However, leaf size and SLA were not significantly correlated across species, suggesting that these two traits are decoupled and associated with …

Biological Implications Of The Weibull And Gompertz Models Of Aging, Robert Ricklefs, Alex Scheuerlein

Biology Department Faculty Works

Gompertz and Weibull functions imply contrasting biological causes of demographic aging. The terms describing increasing mortality with age are multiplicative and additive, respectively, which could result from an increase in the vulnerability of individuals to extrinsic causes in the Gompertz model and the predominance of intrinsic causes at older ages in the Weibull model. Experiments that manipulate extrinsic mortality can distinguish these biological models. To facilitate analyses of experimental data, we defined a single index for the rate of aging (ω) for the Weibull and Gompertz functions. Each function described the increase in aging-related mortality in simulated ages at death …

A Motor And A Brake: Two Leg Extensor Muscles Acting At The Same Joint Manage Energy Differently In A Running Insect, Anna N. Ahn, Robert J. Full

All HMC Faculty Publications and Research

The individual muscles of a multiple muscle group at a given joint are often assumed to function synergistically to share the load during locomotion. We examined two leg extensors of a running cockroach to test the hypothesis that leg muscles within an anatomical muscle group necessarily manage (i.e. produce, store, transmit or absorb) energy similarly during running. Using electromyographic and video motion-analysis techniques, we determined that muscles 177c and 179 are both active during the first half of the stance period during muscle shortening. Using the in vivo strain and stimulation patterns determined during running, we measured muscle power output. …

Cost Of Defense In The Context Of Plant Competition: Brassica Rapa May Grow And Defend, David H. Siemens, Shannon H. Garner, Thomas Mitchell-Olds, Ragan M. Callaway

Biological Sciences Faculty Publications

Theory on costs of plant defense against herbivory in stressful environments predicts that costs should increase when competition is intense. This amplifies a fundamental dilemma that plants are thought to face: allocate limited resources to grow fast enough to compete, or invest these resources in secondary metabolites to maintain defense. We studied costs associated with genetic and environmental variation in secondary metabolite production of Brassica rapa in the presence and absence of the generalist competitor Lolium perenne. We used experimental quantitative genetics (artificial selection) to manipulate genetic variation, and herbivore-induction treatments to produce environmental variation in myrosinase and glucosinolate …

Getting Together In Idaho: A Survey Of Six Collaborative Efforts On Public Lands, Andrus Center For Public Policy

Research and Reports

Collaborative groups -- loosely defined as groups of people working together to achieve a common purpose and share resources – are emerging in Idaho and around the West.ⁱ Collaborative groups often form where there are intense and complex conflicts over natural resource management. Often these conflicts spin off into lawsuits, lost jobs and frequently, fractured community relationships. Many people are turning to each other, believing “there has to be a better way.”

Federal agencies, largely the U.S. Forest Service and Bureau of Land Management (BLM), manage about two-thirds of the land in Idaho. On these federal lands, collaborative partners …

Studies On Use Of Carbon Slurry, A Waste From Fertilizer Plant, In Treatment Of Waste Water, Sanjay Tewari

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

"Non biodegradable materials like heavy metals, refractory organics are not removed during the conventional treatment process. In order to meet the regulatory standards and for safe disposal, it is necessary to go for tertiary treatment. Various tertiary treatment methods include adsorption, membrane separation process, ultra filtration, reverse osmosis etc. Adsorption has been found to be efficient for the removal of most of heavy metals in waste water at lower concentrations. Activated carbon is commonly used adsorbents, however, due to its high cost and loss in regeneration, various low cost adsorbents have been investigated during recent years.

The aim of the …

Relationship Of Effective To Census Size In Fluctuating Populations, Steven Kalinowski, Robin Waples

United States Department of Commerce: Staff Publications

The effective size of a population (N_e) rather than the census size (N) determines its rate of genetic drift. Knowing the ratio of effective to census size, N_e / N , is useful for estimating the effective size of a population from census data and for examining how different ecological factors influence effective size. Two different multigenerational ratios have been used in the literature based on either the arithmetic mean or the harmonic mean in the denominator. We clarify the interpretation and meaning of these ratios. The arithmetic mean N_e / N ratio …

Long-Term Manure And Fertilizer Application Effects On Phosphorus And Nitrogen In Runoff, Bahman Eghball, John E. Gilley, David D. Baltensperger, J. M. Blumenthal

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Long–term manure and fertilizer applications to a soil can increase phosphorus (P) and nitrogen (N) transport in runoff. This study was conducted to determine P and N transport in runoff following long–term (since 1953) manure and fertilizer applications. Duplicate soil samples (32) were collected in 1998 from the top 0.1 m of selected plots of a long–term manure and fertilizer applications field experiment and later placed in 1 m² soil pans in the laboratory. Manure and fertilizer were mixed with 16 of the soil samples, while no treatment was applied to the other half (long–term residual effect). Simulated rainfall …
