: butterflies, pink and lavender with contrasting color in the middle, large, flat, landing platform, nectar offered as a reward (not pollen), nectaries in long tubes (butterflies have long tongues) o Phalaenophilous : moths, white, showy night opening flowers, strong, sweet scents, long tubular nectary’s o Sapromyophilous : flies, brown or orange flowers, strong scent of rotting flesh or dung; no reward (just a trick); high latitude/high elevation or early spring o Ornithophilous : birds, large, showy, red, or orange; long tubes, often without a landing platform, odorless, nectar as a reward o Chirophilous : bats, large, showy white or light colored flowers, bell shaped, nectar as reward Life Strategies What makes a plant “successful”? o Growth, maintenance, reproduction What is a plant “allocation strategy”? o Individuals have limited resources to devote to success so they have to adopt strategies for allocating resources What is an “allocation tradeoff”? Can you provide an example? o Plants cannot dedicate all resources to all things to they have to select one to focus more on such as more focus on reproduction o Example- Poa Annua (annual bluegrass) What is the “multiple limitation hypothesis”? o Plants are flexible in root:shoot ratios therefore each resource is equally limiting; plants may aquire excess resources and they’re still limited What do these words mean: annual, biennial, perennial, monocarpic, semelparous, polycarpic, iteroparous? o Annual : a plant in which the life cycle is completed in one year or less o Biennial : a semelparous plant that flowers after two or more years o Perennial : a plant in which the life cycle is completed in more than one year o Monocarpic : reproducing in a single bout in a lifetime o Semelparous: reproducing in a single bout in a lifetime o Polycarpic : reproducing in more than one bout in a lifetime o Iteroparous: reproducing in more than one bout in a lifetime How is allocation related to both longevity and likelihood of herbivory? o Longevity- the longer a plant is likely to survive, the more likely it is to invest in the cost of maintenance What is r/k theory, and how does it apply to plants? Can you provide examples of each? o r-selected species: shorter lived, higher population density (sheetgrass) o K-selected species: longer lived, low reproductive effort (giant sequoia) What is the CSR theory? What does each letter stand for and mean? o CSR theory: o C= competition competitive o S=stress tolerating

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
