Flowers Vs Pollinator Essay

Improved Essays
Introduction Flowers and pollinators have co-evolved over thousands of years creating the physical characteristics that you see within flowers and pollinators throughout the world. Flower type, shape, color, odor, nectar and even structure in some way are related to pollinators and the need to attract pollinators for reproduction. A major gap of understanding floral evolution starts with the role of the pollinators (Parachnowitsch & Kessler, 2010). Characteristics of flowers can be used for the prediction of specific pollinators. Flowers and pollinators each have their own specific goals and their goals do not technically overlap despite their involvement with each other. Flowers want to maximize their chances of reproducing, continuing their …show more content…
Bike trail (Location #1) next to Guy west bridge and a Secluded Area (Location #2) that is about 50 ft off from the bike trail and is approximately 200m from location #1. Location #1 was positioned at 38 33’ 49” N 121 25’ 10”W and Location #2 was located at 38 33’ 42” N 121 25’ 2” W. The two sites experience Mediterranean and semiarid climate with riparian vegetation. Data was collected through October 2014. Telegraph Weed, Heterotheca grandiflora is a perennial plant that is native to California. Telegraph Weed is one of the few plants that blooms in the fall and giving the best opportunity to study flower number and pollinators …show more content…
Location #1, 10am and 3pm, and Location #2 10am and 3pm. During each time frame, 5 trials was conducted. 10 trails per location and 20 trials total. Telegraph weed comes in many different heights and number of flower displays. Manipulation of three plants in each location was done in order to display the correct number of flower displays. Three display categories were formed, small, medium and large. Small was 5, medium was 10 and large was 20 flowering displays. Displays that were fully flowering were kept and any partial displays were removed in order to be consistent as possible through all trials. Each trial was conducted for a complete 30 minutes. The number of landings by pollinators was collected through each trial. A landing was considered to be a pollinator landing on the telegraph weed, No minimal interaction time was assigned that needed to be met by the

    Bambara groundnut is believed to be autogamous and floral reproduction starts 30 to 35 days after sowing and may continue until the end of the plant’s life (Directorate Plant Production, 2009; Swanevelder, 1998). Flowers are normally carried in pairs on short peduncles by a pedicle which arises from the axis formed by the petioles and the stem (Doku, 1968). Flowers formed on the same peduncle do not open simultaneously, although they will open within a 24 hours interval. Delayed flower opening may be as a result of photoperiod, low temperatures and cloudy skies (Massawe et al., 2003). It has been reported that in Bambara groundnut fertilization takes place on the same day as anthesis (Linnemann and Craufurd, 1994).…

    All three transects at each site were studied at the same time on one day. The transects were studied to look for visiting pollinators at the flowers during each of the 30 minute periods. There were four 30 minute periods beginning at 0900, 1200, 1500 and 1800. During the start of each period an observer would walk for 2 and half minutes down each transect and recorded any of visitors on the study plants. This process was then repeated five more times (Barthell, 2001, 1872).…

    In separate jars, 10mL, 20mL, 30 mL, and 40mL, was added after being measured in a beaker. The dependent variable was the time it took for the solution to return to a clear color, after being shaken for 15 seconds to turn it into a dark blue. After being shaken, the time it took to return to clear was taken on a stopwatch and recorded. For each trial sever factors were kept constant: the type of solution, beaker, type of jars, duration of shaking, and the person timing. The control from the experiment was the average from all 12 trials.…

    The number of ants being captured each day will be calculated by the difference between the initial amount provided (50) and the final amount of ants left after each day. The number of ants left will be recorded at the same time for all subjects so all of the plants will have the same time to capture preys. The length and width of each lid will be measured, and the surface area will be calculated. I will conduct 3 trials in this experiment, each time with 3 subjects differing in the lid size, ranging from large to small surface area. And after the time span of one month, the total amount of ants captured in one week along with the average amount of ants being captured per day will be calculated for each subject and the data recorded will be compared.…

    On 8th day ten seedlings from three replicates were chosen randomly for measurements of shoot and root growth, fresh weight of the seedlings, disease incidence, and vigour index. Vigour index was calculated by using the following formula as described by Abdul Baki and Anderson (1973): Vigour index = (Mean root length + Mean shoot length) × Germination (%) Triggering of Induced Systemic Resistance Leaf samples (1g) were collected from each treatment on zero…

    Each session was completed in about 20 minutes. Perception Span measured the speed and span of recognition and Eye-Hand Coordination measured reaction time. Go/No Go also measured reaction time while the Reaction Time assessment measured central eye-hand reaction and response time. After analysis and subject feedback, the researchers made modifications to the equipment, instructions and protocols in order to improve the reliability of the tests. In Phase II, 36 subjects (20 men, 16 women) who had not participated in Phase I were recruited.…

    Now you will place one raisin in each beaker and set a timer for 10 minutes. After timer goes off you will then take tweezers and remove each raisin from the water, blot it dry, and weigh them. Record the data in your chart. You repeat this every 10 minutes for a total of 30 minutes. So you should have a weight for each raisin at 10 minutes, 20 minutes, and 30 minutes.…

    On Lab Quest Mini, the collection rate was set record data every four seconds for a period of 420 seconds (7 minutes). We weighed 30 grams of spinach using a digital scale; we allowed time for the spinach to breathe for 3 minutes while fluffing the spinach up between trials and rotated the spinach out every third trial. For each trial, the spinach was placed in a sealed container with the CO2 and O2 sensors. We began collecting data as soon as the lid was sealed on and the light was turned on. Light filters included two bottles of water placed in front of the light as a filter.…
