Concepts

Pikas as island species restricted to talus habitat and high alpine mountain tops

Correlation between canopy growth in one year and stem growth in the following year rather than the same year

Intricate networks of veins built from lignified xylem and phloem tissue that serve multiple functions including transport of water and sugars, mechanical support, and herbivory resistance

The minimal PAR required by the plant to absorb more carbon dioxide than it is releasing, found at the x intercept of the PI curve

Hypothesis that social relationships provide direct emotional and behavioral aid that encourages healthy lifestyle changes

The concept that masculinity is performed and constructed rather than innate, revealed through character staging and cultural fabrication

The principle that mass cannot be created or destroyed, applied to nutrient cycling as consumption - growth - egestion = excretion

A theoretical framework that derives universal SAR formulae from information theory principles

Student perceptions of the quality of relationships and support received from research mentors

Rate of energy expenditure or metabolic activity in plant species

Plastic particles smaller than 5 mm that result from fragmentation of larger plastic pieces

Pulverized waste rock not containing useful ore, typically deposited as slurry or fine dust, often containing toxic metals and chemicals

Physical limitations imposed by body structure that affect foraging efficiency and resource use

Activities related to building and maintaining nests, including burrow digging and gathering nest materials

Colors that stimulate multiple cone types simultaneously but cannot be produced by monochromatic light, such as purple

Controlled studies that alter nutrient availability to test ecological responses

A framework to investigate how organisms optimize nutrient acquisition in complex environments by targeting specific nutrient compositions

Fat content and biomass composition of ant nests as food resources for bears

Uses small mammals as a food source to rear young

Barriers that can be impediments to individuals participating in outdoor recreational activities, often reflected in sociocultural issues

Life cycle strategy where organisms take more than one year to complete development

Visual detection capability to the sides while foraging that can be blocked by obstructions

A measure of asymmetry in the distribution of phenological activity timing, quantified as the Fisher-Pearson standardized third-moment coefficient

A behavior in which an organism uses a host, typically of a different species, as a means of transportation
