Plant physiology

carnivorous plants who use their specialized pitcher-shaped leaves to capture their prey through passive pitfall traps (Bauer, Di Giusto, Skepper, Grafe, Federle, 2012). The adaptation of carnivory in plants is as a result of nutrient-poor habitats in which the fitness of the plants depends on the availability of animal prey in that habitat. Animal prey increases seed production, flower production, and biomass, which are all essential for plant fitness. As a result, carnivorous plants use many…

is a free- floating aquatic plant from the duckweed family, that consists of small, individual thalli (Tkalec et.al, 2001). Lemna are small, fast growing plants and they develop dense mats on ponds, especially when enough light and nutrients are available (Gérard et.al, 2014). Salt is the most toxic substance, as it causes an inhibition of plant growth and a decrease in nutrient uptake (Chang et.al, 2012). Salt stress induces the production of abscisic acid (ABA), a plant stress hormone, which…

SUMMARY The efficacy of abamectin , malathion and three plant oils(olive oil, peanut oil and linseed oil) singly and in three mixture ratios (5:95, 10:90 and 15:85) of the oils and pesticides , were biologically evaluated on cowpea beetle, Callosobruchus maculatus ( Fabricius , 1775) infested cowpea seeds. The activity of abamectin and malathion singly or in mixtures with the three oils were significantly increased, particularly at the higher concentrations. abamectin combinations with olive…

Endangered species are organisms that have such a reduced population that they are threatened with extinction. There are thousands of different species that are included in this list. Millions of years before humans existed, causes of extinction of living things were mostly linked to geological and climate effects (environmental change). Even though, environmental change is still the primary root for the extinction of organisms, but now the process of extinction is accelerated by human…

Fight silverfish in the bedroom Silverfish find ideal living conditions in human habitations. In addition to the bathroom , the bedroom also offers optimal living conditions for the small animals. The insective insects belonging to the insects feel particularly well because of the prevailing temperatures and humidity. Although they are not really harmful to health and in the widest sense even useful, nobody wants to share their home or sleeping with the voracious animals. Often silverfish are…

crustaceans, a variety of fish species, wild life such as the national bird of Trinidad and Tobago, the Scarlet Ibis, Ruschberger’s Tree Boa, caimans and other species of birds both migratory and endangered. There is also a large ecosystem of herbal plants found in the mangroves. Both plan and animal life along with the structure and geographical location are what can be considered the source function of the Caroni Swamp. The sink function of the economy is the environment’s ability to remove…

Most threats facing animals and plants at present can be linked to human influences. Habitat destruction is the greatest contributor to the extinction of species. Human actions which threaten biodiversity can be divided into two categories, deliberate actions and unintentional actions. Many habitats for example, swamps, wetlands, forests and other habitats get destroyed for human consumption and industrial gain. By destroying habitats, many different animals face death because they no longer…

something must be done to eliminate these threats. These strategies could include, - To track down and kill the species, humanely. - To provide rewards to the public for getting rid of them. - To create a poison that is placed on native plants, that isn't harmful to the plant, and only to the species that are to be killed - Put bans on imports of these species, to…

African sulcata tortoise is one of the largest tortoises in the world. Its protruding spurs in its feet have no function at all. These turtles are very easy to maintain with an average weight of 80kg. Since it is large enough, it is not suitable to be kept in the house. The breeding must be outside the house like garden. This tortoise has a longer life than the average human. Sulcata classified as herbivores that eat fruits and vegetables. Here are the characteristics of sulcata. They do not…

Destiny White We all use paper in our everyday lives but do we ever realize what people do so that we have it. Paper companies all around the world cut down many trees that we use to survive. In the text, “The Sumatran Rainforest Will Mostly Disappear Within 20 Years”, John Vidal informs readers about all of the risks that the Rainforest is taking in order to have create paper and other products for the world. Taking away the trees in the Sumatran Rainforest harms animals. Also, cutting down the…
