Bats can also play an important role in maintaining the genetically continuity of plant population and have considerable conservation value. There are two families of nectar feeding bats which are pteropodidae, occur throughout tropical and subtropical regions of Africa and phyllostomidae which inhibits tropical and subtropical regions of America (Fleming et al., 2009). Hummingbirds are considered to have the highest dusk or soon after, are large, white or pale yellow in colour, have odour and produce large quantities of nectar Flower for bird produce ample pollen and nectar as reward (Momose et al., 1998). Flowers of the bat-pollinated species were dull-coloured, emitted odour, opened in the evening, and had wide apertures and rigid pedicels, which positioned them beyond the foliage (Muchhala, 2006). Non flying mammals tend to pollinate plants with robust flowers, dull coloration, copious amount of nectar and exerted styles and stamen (Carthew and Goldingay, 1997 as cited in Jensen et al., 2001).
Background The point of this analysis is to compare the abundance of Stonefly Nymphs in rifles vs. Poles. EXPLAIN The Plecoptera are an order of insects, commonly known as stoneflies. There are around 3,500 species worldwide, with new species still being discovered. Plecoptera are found in both the Southern and Northern Hemispheres and the populations are quite distinct. All species of Plecoptera are intolerant of water pollution and their presence in a stream or still water is usually an indicator of good or excellent water quality.
The last error that may have occurred due to tape. Though caution was emphasized, and extreme carefulness had been placed in the taping process, some tape may have gotten inside the bottle, and fruit flies may have been stuck to it, which had skewed data. The lab manual from College Board, which states, “The common fruit fly….feeds on the fungi of rotting fruit,” (College Board 2004) reinforces the hypothesis clearly, and depicts chi square values with values such as 18.75. Experiments performed in UC Davis show that “fruit flies are regularly trapped….by yeast, and “the chemicals released by microbes…. [attracted] more flies.” (Garvey 2014) Some ways to improve the lab are to make sure that the error sources are fixed.
Both of these sloths can be found in nearly all elevations with the three-toed going up to 2400 m and the two-toed being seen as high as 3,300 m (Wainwright). While both kinds are found in primary forest, secondary forests, and subtropical lowlands, the three-toed is much more commonly seen. This is due to the fact that the three-toed is active during the day and night, while the two-toed is mostly nocturnal (Wainwright). Both sloths spend nearly all of their time in the tree canopy and for the most part they do not prefer specific species of trees. Three-toed and two-toed sloths have little muscle mass and low heart rates, so they do prefer to be in taller trees in which they can bask in the sun in order to maintain a warmer body temperature (Jung, Apostolopoulos).
Tropical forests refer to a very wet place which experiences heavy rainfall either throughout the year or seasonally. These forests are usually located near the equator where there is an abundance of sunlight and warmth. The temperatures here are usually uniformly high registering between 20 to 35°C. As a result of the high rainfall and sunlight, tropical forests are evergreen all year round (WWF, 2016). Besides beautifying the area its located in with greenery, tropical forests have many other key roles in this globe.
iv. Ara et al. (2014) collected fish larvae by using bongo nets with mesh size 500 µm, mouth diameter 0.3m and length 1.3m (Figure 2) in daylight. A flow meter (hydro-bios) was attached to the net in order to determine the volume of the water filtered. The bongo net, then towing 30 minute sub-surface from each station.
The combination of three main types of grasslands which is tropical, temperate and polar lead to low average precipitation and fluctuations of average temperatures. Discussion There is three types of grasslands -tropical, temperate and polar grassland which will be discussed one by one except polar grassland because we don’t have one in South Africa. What is tropical grasslands? Tropical grassland is an area which has warm temperatures, adequate rain fall except during dry season. Tropical grassland consist of herds which grazing grass and some browsing animals that feed on a broad different tropical plants such as buffalo, kudu, 2 waterbuck, warthog, zebra, giraffe, rhinoceros, wildebeests etc.
Rainforest Rainforest contains approximately two-third of the world’s plant and animal species. It has one of the world’s most spectacular ecosystem. The name ‘rain’ forest, indicates that it receives high rain fall throughout the year. Not limited to that, the trees also release water to the atmosphere by transpiration, forming dense clouds that surround the forest. Hence, even on non-raining days, the forest remains warm and humid.
1.1 INTRODUCTION The butterfly is an insect from Order Lepidoptera. They are known as the second largest order of arthropods and most easy to find and identified (Alarape et.al, 2015). It includes in two groups of Lepidoptera, which is Rhopalocera group while another group is moths under Heterocera. The butterfly is a day-flying (diurnal) insect and usually brightly colored and often exposed to sunshine which can distinguish them with moths. The butterfly has two pairs of large wings which covered with scales and sometimes got hairs (Abang, 2006).
These forests are important for our survival as they are not only a natural home for many animals but also crucial for maintaining the average temperature of the planet and checking carbon dioxide levels which have been increasing to a disturbing level. With the Homo sapiens expanding their territory, the existence of many such significant forests is becoming a concern. We have on this earth some of the largest and densest forests, of which some are those which haven’t even been stepped upon yet by humans and God only knows what mysteries they have concealed in them. 10. Sinharaja Forests, Srilanka sinharaja forests, srilanka Sinharaja rainforests are the most prominent rain forest of Srilanka and are located in its south-west lowland wet zone.
