Fine-scale habitat use by black-footed ferrets (Mustela nigripes) released on black-tailed prairie dog (Cynomys ludovicianus) colonies in New Mexico
Black-footed ferrets (Mustela nigripes) are among the most endangered animals in North America. The dependency of ferrets on diminishing prairie dog {Cynomys spp.) colonies for prey and shelter has been detrimental to their ... -
Eco-physiological drivers of geographic range limits in two closely related euryhaline fish species
A fundamental goal in evolutionary ecology is to understand the problem of why species occur in some environments and not others. Indeed, a general pattern in nature is that many organisms occupy only a subset of the total ... -
Three-dimensional reconstruction and finite element modeling of anuran middle ear biomechanics
The ancestors of modern-day amphibians were the first vertebrates to evolve a middle ear for land-based hearing. Today's amphibians retain a simple and effective middle ear structure similar to those of their ancestors, ... -
Selenium transport in plants with a special focus on selenium hyperaccumulators
The aims of this thesis are to synthesize current knowledge of selenium (Se) transport and metabolism in plants and improve understanding of Se transport in a class of plant species known as Se hyperaccumulators (HAs). ... -
Dataset associated with “An in-frame deletion mutation in the degron tail of auxin co-receptor IAA2 confers resistance to the herbicide 2,4-D in Sisymbrium orientale”
The natural auxin indole-3-acetic acid (IAA) is a key regulator of many aspects of plant growth and development. Synthetic auxin herbicides such as 2,4-D mimic the effects of IAA by inducing strong auxinic signaling responses ... -
Loss and integration: tracing the functional replacement of mitochondrial tRNA genes
To view the abstract, please see the full text of the document. -
Soil nematode community response to climate change and associated alterations to precipitation and vegetation
Understanding of the belowground grassland response to climate change is much more limited than aboveground responses. This disparity in knowledge is partially due to the vast diversity in species in belowground ecosystems ... -
Are you what you eat? Assessing intracellular effects of supplemental lipid within mouse (C2C12) skeletal muscle cells
The expression of myoglobin, an oxygen-binding protein, facilitates aerobically-powered dives by effectively distributing a finite oxygen supply during breath-hold dives in marine mammals (Costa 2004, Kanatous et al. 1999, ... -
Effects of genome expansion on transposable element diversity in salamanders, The
Transposable elements (TEs) are repetitive sequences of DNA that replicate and proliferate throughout genomes. Taken together, all the TEs in a genome form a diverse community of sequences, which can be studied to draw ... -
Protein interactors of AtSR1 mRNA during salt stress
To survive adverse conditions, plants must respond physiologically to biotic and abiotic stresses. Stressors are detected via primary sensors in the cell wall and plasma membrane to elicit a host of secondary signals, such ... -
Dataset associated with: "Intentional mentoring should increase inclusivity in ecology"
High quality mentoring relationships can be pivotal to recruitment, retention, and long-term persistence in ecology majors and careers. The graduate-undergraduate student mentoring relationship can become uniquely important ... -
Dataset associated with “NSF Noyce Phase II: Empowering Scholars and STEM Teachers” project
The CSU Noyce program was supported by the National Science Foundation Noyce Program. Funding supported undergraduate majors in science, technology, engineering, and mathematics majors who were also enrolled in CSU’s ... -
Prickly puzzle, A: phylogeny and evolution of the Carduus-Cirsium group (Cardueae: Compositae), and untangling the taxonomy of Cirsium in North America
Generic delimitations within the cosmopolitan Carduus-Cirsium group (i.e., "thistles") have a long history of taxonomic confusion and debate. We present the most comprehensive molecular phylogeny of the group to date to ... -
Inter-individual variation within social groups: how metabolic rate shapes the pace of life
Metabolic rate (MR) is often cited as the fundamental rate which determines the rate of all biological processes by shaping energetic availability for the various physiological, behavioral, and life-history traits that ... -
Temporal examination of myoglobin and myosin heavy chain expression patterns in vitro
Myoglobin is a hemoprotein expressed in vertebrate muscle that is typically known to follow an established oxidative muscle fiber type, found in aerobic muscles. However, more recent evidence has demonstrated changes in ... -
What in your right mind would make you do that?? Proximate and ultimate mechanisms of plasticity in mating strategies by the Trinidadian guppy (Poecilia reticulata)
All animals must make decisions every day and often these decisions are directly linked to fitness outcomes, meaning better decisions are expected to be associated with higher fitness. Rapid decisions between alternative ... -
Initiation and regulation of iron economy in Arabidopsis thaliana chloroplasts
Iron (Fe) is biologically important for all organisms because of its role as a protein cofactor which provides redox and catalytic functions. Fe cofactors come in 3 different forms (Fe-S clusters, heme, and non-heme Fe). ... -
Data associated with "The importance of extreme rainfall events and their timing in a semi-arid grassland"
Climate change is intensifying the hydrologic cycle globally, increasing both the size and frequency of extreme precipitation events, or deluges. Arid and semi-arid ecosystems are expected to be particularly responsive to ... -
Identification of a gene that makes-plants-gigantic-1: characterization of mpg1, a novel mutant of rice
The growing world population has been putting considerable strain on energy and food demands. To address the ever-growing need to meet these demands and service the global populous, emphasis has been placed on developing ...
