Dominant species identified were Cannabis sativa, Oxalis corniculata, Cynodon dactylon and Digitaria setigera. Cannabis sativa, the most frequently occurring specie of study area, is a wild herb and grows in moist and waste places near houses and along roadsides. It is common weed found throughout of Pakistan (Abbasi et al., 2011). As far as second most dominant species Oxalis corniculata is concerned, it is found in temperate areas having moisture and sunlight like waste places, cultivated lands in loamy soil, gardens, yards, driveways and sidewalk cracks (Abbasi et al., 2011; Eiten, 1955). Another prevalent species, Cynodon dactylon is commonly found in warm and temperate climates of world (Kole, 2011). Natural population are highly tolerant toward soil salinity (Pessarakli, 2007). Cynodon dactylon appeared as most dominant specie with RF of 47.5% followed by Cannabis sativa with RF of 17.9% in Islamabad as stated…
the collection of phytosociological data. One contained site number, name, collection date, length of the site, number of quadrat, name of the individual, etc. which were used for tree, shrub and herb species, whereas other used only for tree species that contained circumference of the tree at breast height (Cbh), canopy and height of the individual tree species. Formats used for the collection of herb, shrub and tree species data List of the sites of the Petlad…
Kishan Patel Section: 008 Pattern: Calcium levels in the soil controls soil pH and species richness within a community Hypothesis 1: Calcium levels in the soil controls soil pH. Prediction: An increase in the calcium levels in the soil will make the soil less acidic. Reasoning: Calcium exists mainly in the soil as exchangeable cations (ca^2+) associated with basic anions, which reacts with soil acidity (H) to neutralize it. Analytical approach: Regression Independent variable: Calcium levels…
When looking at the data provided, the trends of native-species increase in the restored area and the abundance of exotic species seen in the degraded areas provides an idea of how effective the restoration efforts where at restoring them to the reference site. To begin, the data provided in table 5 gives an idea of the distribution of the number of species found at each site, and how much of a contrast is shown between the restored and degraded areas and how they compare to the reference site.…
involving the heavy invasion of species imperfect systems. Biological Invasions, specifically invasive species are exotic species that cause environmental…
flowers Coevolution is a situation where two parties are able to evolve to satisfy each other’s needs. In this particular case we are going to talk about the coevolution of hummingbirds and ornithophilous flowers. Plants are one of the most important species in our world. Mainly it helps us breathe that very fresh air we have today. Although it may seem to be impossible for one to think a simple plant can help us breathe. It is also another species that helps it reproduce and spread. By doing…
RELATIONSHIP BETWEEN SPECIES DIVERSITY AND SIZE Effect of Surface Area on the number of species in biodiversity. Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be. Species diversity is the variety of organisms that make up a community It has two components: • SPECIES RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain…
Results Mammal detection Ground-dwelling mammals triggered 89,581 images or 53.3% of the total images over 3640 camera days. Ten terrestrial mammal species were identified from all study sites (full list in Appendix 1). Swamp Wallaby, Bush rat, and Long-nosed Potoroo triggered most of the images containing terrestrial mammals. Swamp Wallaby, Short-beaked Echidna, Bush Rat and Eastern Grey Kangaroo were widespread over the study area. With the exception of Dusky Antechinus and Long-nosed…
ecosystem. This variety can be between species, within species, and between ecosystems, but in this lab, only the variety between species will be discussed to quantify the biodiversity of the target ecosystem. Biodiversity can be quantified by two main aspects which are species richness, and species eveness. Species richness is the number of species observed per sample of an ecosystem, and if there are a higher amount of different species within one sample of an ecosystem, then that sample is…
Complex, in Rock Hill, South Carolina. The experiment was formed to determine the amount of species richness in both general areas. The hypothesis that was formed stated: that the Winthrop Lake area would have a greater amount of species diversity than the golf course area based on effects of temperature, wind speed, and local habits. When going into these locations groups of six individuals were formed. Two people observed the birds, two people determined the species of the bird, one individual…
