In northeast Brazil, the capuchins have a food source limited to hard shelled fruits and seeds. As a survival adaptation they learned how to make use of the available sources by the use of stone tools. Interestingly enough, they don’t just use any old rock that they can find. The capuchins make sure that their “hammers” are the perfect size to swing with but are also made out of a hard enough material- such as quartzite. Sandstone is usually used as an anvil. The perfect tools don’t just go to…
and timing of rainfall in a season. Once flowering occurs, the yucca moth pollinates neighboring Joshua trees while laying its eggs inside the flower. Without this moth the Joshua tree could not reproduce, nor could the moth, whose larvae needs the seeds as nutrient. This connection between the Joshua tree and yucca moth is a clear example of a symbiotic relationship. This crucial exchange could be in jeopardy with the impending climate change. Climate change will affect the timing of the…
Results Effects of cultivar genotypic diversity on weeds In overall, the total density of weeds grown in genetically diversified wheat plots was significantly (P ≤ 0.01) lower than that in the monocultures (Figure 2). Weeds grown under monocultures of Shiroodi and ERWYT 91-11 showed the highest density, 33.33 and 30.17 plant m-2 respectively. However, the lowest weed density, 18.67 plant m-2, was observed where these two genetically diversified cultivar/line grew together in a mixture (Figure…
II. Nature is not a Museum The gymnosperms are often called ‘Living Fossils’, or are dismissed as being primitive. Gymnosperms are indeed ancient: originating in the carboniferous period (Bowe, Coat, & dePamphilis, 2000). They can be divided into four monophyletic groups: ginkophytes, gnetophytes, cycads, and the largest of the four (with more than 600 extant species), conifers. Conifers account for the greatest diversity amongst the gymnosperms. This diversity might pale in comparison to that…
produces seeding the second. For root production the plant is grown as an annual. Low temperatures, as well as various stress factors, will sometimes cause flower production to be initiated, particularly in certain selections of some varieties. Bolting to seed in spring is possible in carrot plantings grown over the winter period. 2. ADAPTABILITY 2.1 CLIMATIC…
Methods: To start this experiment place four seeds in four separate petri dishes with a damp paper towel. Once the seed germinates and the plant has begun to sprout, move the seeds to four separate pots, and add soil. Once the plants have begun to sprout take the measurement of each plant and record your data for day zero. Next, take three glass containers of greatly varying volumes (41,4185cm3, 2,250cm3, and 602cm3 were used). Before the plants are placed underneath these containers, give…
Ziziphus mauritiana and the Muzarabani community. Wild fruits are widely managed and utilised in different parts of the world. In semi-arid region the dependence on the fruits vary from region to region. In semi-arid regions which are prone to natural hazards like Muzarabani have for years relied on wild fruits’ like Ziziphus mauritiana despite, the reliance of the people of the muzarabani community on Ziziphus mauritiana , serious academic considerations of Ziziphus mauritiana as is an…
My phage has the wonderful name of Lorge. This name is very special because it offers information about the phage right away. I also chose this name because the first word that Tracy said when she saw my phage was, “Wow, it’s huge!” To get this wonderful phage I collected the soil sample from the flower pots across the street outside of Bessey Hall. I got the sample at the start of class on September 11, 2017. It was a clear day that was 60 degrees, with a depth of about 4cm below the surface of…
