1. Short Description of the bird (include scientific name, IUCN assessment, physical features) The Grenada dove, (Leptoltila wellsi) is endemic to Grenada only. According to Oxford Dictinary (2018), define endemism as “the degree which the plants and animal of a particular area are both native and restricted to it”. The ICUN assessment shows, Leptoltila wellsi is critically endangered on the red list. Although its population is small scale it detrimentally decline due to hurricanes, residential…
“A DEVIL, BORN DEVIL UPON WHOSE NATURE, NURTURE WILL NEVER STICK” THE TEMPEST (WILLIAM SHKESPARE) According to Sir Francis Galton (1822-1911), Nature is everything which a man brings with himself to the world while Nature is every influence that affects him after birth. The nature versus nurture debate has been a controversial issue and it can be traced to about 150years ago. In 300BC some philosophers questioned nature vs nurture in human behaviour. A Greek philosopher named Plato (428 BCE –…
Charles Darwin came up with the idea of natural selection which is the genetic change or changes in the frequencies of certain traits in populations due to differential reproductive success between individuals. At the time charles darwin was coming up with the idea of natural selection religion played a big part no one knew of anything different so having a new idea come forth was shocking to people, the idea of natural selection people couldn't even think about happening, everyone just wanted…
various species, with optimal survival traits would outlast and thrive in contrast to those with less beneficial traits. Lamarck, father of evolution theory, would have believed these traits would have been slowly formed due to necessity and bred down through generations. Now, of course, modern technology has greatly enhanced the understanding of genetics, evolution is considered not just to be caused by environment…
2.8 Protected Areas and Wildlife Management Wildlife management has been defined as the attempt to create a balance between the needs of wildlife and that of humans (people) by adopting and using the best strategies proven by science (Fred, 2008). Wildlife management according to Potter (1973) is a unified discipline with an attempt to achieve best results. Wildlife management includes practices such as game keeping, pest control and wildlife conservation. Soule (1986) argued that wildlife…
Kwon-Chung in 1976 has mentioned that C. neoformans exists as two mating types, MATa and MATα which is determined by single locus with diomorphic alleles.(Halliday CL et al, 1999). The MAT locus of C. neoformans is larger and consists of 100 kb having more than 20 conserved genes. These mating types play an important role in sexual development changes. These also play a vital role in epidemiology by knowing the prevalence and virulence of the isolate (Lengeler KB et al, 2000). Based on the…
Thought you knew all there was about rabbits? Think again. In this overview we're going to take a look at 15 facts about rabbits that'll surely tantaliize your mind. 1) Rabbit Symobolism Due to the fact that rabbiits are well known for their prolific reporductive nature, it comes as no surprsie that the rabbit is a symbol of fertiflity in many relgions and cultures.

Importance of Microbes Introduction It was long ago when Man realized that, along with animals and plants, he was also accompanied by some other organisms as well, and though which remained hidden from his eyes. Those organisms were unveiled by Anton Van Leeuwenhoek, who first saw the tiny organisms which accompanied Man through the lenses of microscope. Later it was found out that microorganisms inhabited each and every surface of earth, on man himself, or even inside him, resided under the…
Nature vs. Nurture Donald Hebb once asked "Which contributes more to the area of a rectangle, its length or its width?” (Jasuja, S., Sehgal, thefoxmancometh@ymail.com, 2015, Para. 2). Scientists have been debating for decades on whether nature or nurture has the biggest impact on human development, and until this day there is no definite answer. Is it biology that determines how we turn out to be as individuals, our genes, DNA and family line? If you agree, then you are on the nature side of…
All of whom saw the variation caused by breeding or artificial selection to acquire a desired trait. Darwin just had to puzzle together the missing pieces and voila. He proves evolution. Sounds simple in theory, but the amount of investigation Darwin put forth is astonishing. If you read On the Origin of Species, it feels like a journey as Darwin starts with the simple foundation of his ideas and expands into a masterpiece of scientific…
