1. Anolis cristatellus and A. cooki are both trunk-ground anoles that live on Puerto Rico. A. cristatellus lives in a shady, forest environment, while A. cooki lives in an open, sunny environment. What is an adaptive explanation for why the dewlap of one species evolved to be brighter and that of another species darker? The A. cristatellus has a brighter dewlap and the A. cristatellus has a darker dewlap since the dewlap is a piece of skin that male anole lizards uses to attract females. Dewlap…

Austrian pine (Pinus nigra) tolerates well both hot and colder temperatures, also drought. This is due to the dense horizontal root system that goes deeper than most Pinus species'. (Magyar 1960) As a tree that feels itself home mostly in continental mountain ranges and the Mediterranean climate, its home range stretches from Iberia through the Alps to the Taurus mountains in Asia Minor. It is medium to fast growing with a pyramidal crown. It is mostly resistant to breakage. (Gilman-Watson,…

Pollination syndromes in large flowered plants. The land is more beautiful when it is that season of the year when flowers are scattered everywhere. Flowers are sunshine, food and medicine for the soul. A flower is sometimes called a bloom or blossom, it is the only reproductive structure found in flowering plants. Its biological function mostly it is to outcome reproduction through a mechanism of the amalgamation of sperm with eggs. They may go through what is called outcrossing and selfing. In…

Why are they Endangered? There are various reasons why the Amur leopard is endangered, such as the destruction of their habitat, hunting and inbreeding. Firstly the prime area in which the Amur leopard lives is the forests of Eastern Asia. These forest areas are often purposefully burnt down by the local villagers to help the profitable growth of ferns. These ferns are a very popular ingredient in local Chinese and Russian cuisine. The forest fires are the largest contributor to the Amur…

Plant Material Collection Fully grown whole plants of Tribulus terrestris Linn. were collected from different localities of Chennai, Tamilnadu. The fruits were separated out from the plants and washed in running tap water to remove adhering dirt and soil particles and dried first under shade in room temperature and secondly in a hot-air oven for complete drying at 50-60˚C. The dried fruits were made into coarse powder by grinding and stored in labelled bottles for further study and…

saprophytic fungi cause decay and decomposition in various bodies of dead animals and plants. Due to their property of decomposition they convert various complex compounds into simple compounds by secretion of certain types of enzymes. Some of these simple compounds are then absorbed by soil which results in the formation of humus. Certain fungi produce associations with the roots of plants and helps them in taking up of nutrients. This association is called Mycorrhizal Association. They…

carrots, lettuce, apples, etc. All the products are fed lizards must be previously well washed.

For almost eight million years, humans lived in small bands or groups that were mostly family based, mobile, and almost had no specialization of skills. But for the last ten thousand years humans have been living in states; densely populated, economically complex, socially unequal, governmentally controlled, unstable, and urban civilizations. There are many positives to living in such a manner, but this way of living does have some negatives as well and can be a less satisfying way to live.…

the main producer is plant that plays a very significant roles in order to sustain the growth population. Basically, plant producing their own food by undergo photosynthesis in the help of sunlight energy. The next trophic level which is herbivore will consume it and proceed to next food web. This phenomena lead to determine either the growth rate in certain ecosystem or habitat is higher or lower. For example paddy plants, it is only life once, which means once the paddy plants harvest it will…

refers to the general geographical area and includes vegetation types such as Forest, Nama Karoo, Succulent Karoo and Thicket Biomes. The fynbos biome only covers about 6, 7 % of South Africa and has the highest number of plant species than any other biome in our country. About 7 500 plant species are found within the fynbos biome. Figure 1: Map of the fynbos biome Apart from its uniqueness, the fynbos biome is also very threatened…
