C1
plant or organisms selectiveness on a mutualist partner or parasitic host refers to ____________
Specificity
Is Nutrient Deficiency or Precipitation an Abiotic Stressor?
Precip
Broadly, instances where one species benefits from another species is an example of another are referred to as ______________________.
Positive Interactions
The ability to cope with short-term deviations to abiotic and biotic stress is also known as _______________________?
Stress Resistance (plasticity acceptable)
The Yucca Moth x Plains Yucca is relationship that is of high specificity for each species, which then we refer to them as __________________.
Specicialists
We discussed three major players in the act of stomatal closure. Absicsic acid, was one of these players which is considered a Phyto________.
hormone
_________ - __________ are plants that provide benefit to smaller plants (e.g., microhabitat, shade), typically in more arid environments
An unfavorable condition which affects a plant's growth, development, or metabolism is called ____________
Stress
While Stress refers to the set of conditions that drive animals away from equilibrium, _________ refers to the induced change brought on by stress.
Strain
Plant-Plant interactions where all parties involved receive benefit from the other.
Mutualisms
As environmental stress increases, we typically see a shift from plant's competing with each other to facilitation, which is generally known as the _________ - ______________ Hypothesis
Stress Gradient
Dependency, is a concept that describes how much a plant depends on what___________ from who _________?
goods and services (resources)---mutualist parnter
90% of vascular plants depend on nutritional mutualisms with what biotic organisms? Be Specific.
Nitrogen-fixing bacteria
_____________ - ______________ is triggered when a receptor protein comes into contact with a hormone, triggering reactions that produce secondary messengers and a signaling cascade throughout the cell to solicit a behavioral response
signaling transduction
Relationships between mutualistic partners with low specificity means that the species is probably a __________________.
Generalist
Plant Mutualisms are typically associated with 3 major relationship types: Which are?
Defense, Dispersal, Nutritional
Terpenes, among other allelopathic chemicals, are also called _____________ chemicals, which are released by plants in response to elements of stress.
Semio
These plants can photosynthesize on their own, but require some resources from a host plant.
Hemiparasites
Ultimately, this phenomena keeps stomata open, but will dissipate when signaling cascades solicit stomata to close, which is _________ - ___________.
Turgor Pressure
Insects responding to semiochemicals released by plants after acts of herbivory to come to aid the plant is an example of _______________?
Defense Mutualism
Based on the level of dependency with a mutualist partner, plant-plant mutualisms can range from being __________ mutualisms which are essential for survival or ___________ mutualisms which are not.
Obligate & Facultative
Facilitation differs from ____________, in that we don't whether one plant receives benefit from the other, but at least one plant does. Typically there is no visible signs of stress from the plant we don't know the condition on.
Commensalism
These chemicals ____________, are typically released from a plant following ___________ damage which solicits a response from nearby insects
Semiochemicals & Phytophagus
Like disturbance, the duration, severity, and frequency of stress will influence how a plant responds to stress. However, plants generally only have a few options. Proximal Acclimation is an option for low severity, immediate changes within an environment. But what are the other two options?
Ultimate Adaptation or Death
Broadly, the mutual filter hypothesis states that the lack of biotic mutualisms in a given area will limit what?
Establishment of a plant community.
