where organisms adapt to their environments in order to stand a better chance of survival. The diversification of a species in evolutionary terms ….organisms diversify rapidly into a multitude of new forms in response to evironmental niches. The cichlid fish in Lake Tanganyika are a prime example of adaptive radiation as they have evolved parts of their
The Genetic Improvement of Farmed Tilapia (GIFT) Project launched in 1988 has created a massive impact. The keys to success are the right selection of specie, investment in R&D, successful dissemination and partnership strategy. Although challenges still lie ahead, the GIFT project undoubtedly opened up a path to fight the global hunger and poverty through aquaculture. Background Since the Green Revolution took place in the 1970s, genetic improvement of plants and livestock has played an important
all over the world. One type of fish that is the most popular are cichlids. Cichlids are one of the largest vertebrate families in the world. They are most diverse in Africa and South America. Africa, by far, contains the largest amount, but the actual number of species is unknown, with estimates varying between 2,000 and 3,000 (Carleton 2009). Cichlids species sizes range from as small as 2.5 cm to about 1 m in length. Many cichlids play vital roles in things other than the aquarium hobby. The most
Introduction First of all, what is Aquaponics? Aquaponics refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken
The research of pigments has performed an important part in the junction of progress, genes, and developing chemistry. Pigmentation's application as a visible phenotypic marker has resulted in over 100 years of intense research of cover shade stresses in lab rats, thereby creating an impressive record of applicant genes and an knowing of the developing systems accountable for the phenotypic results. Coat shade stresses in lab rats have served as a premier design for learning gene action in a wide
Deep in the sub-Saharan land in Africa, is the country of Malawi. Little was known about this mysterious country until the early 1900s. Now we know Malawi has an abundance of rich culture, filled with fascinating history from prehistoric times to the present. Malawi is spread across 45,747 miles of land (which is about the size of Pennsylvania). It is bordered by three nations. In the north is the country of Tanzania, in the south is Mozambique, and toward the east is the nation of Zambia
“In the creation of the heavens and earth, and the alternation of the night and day, and the ships which sail the seas to people's benefit, and the water which Allah sends down from the sky - by which He brings the earth to life when it was dead and scatters about in it creatures of every kind - and the varying direction of the winds, and the clouds subservient between heaven and earth, there are Signs for people who use their intellect.” (Surat al-Baqara: 164) Fish are one of Allah’s mighty creations
Did you know that the frog species were the first animals with vocal cords? Did you know that seahorses are actually fish not little serpents or mermaids as legend tells us, and that it is the male who becomes pregnant, not the female? Did you know that an area of a rainforest the size of a football field is being destroyed each second? If not, then you should definitively consider making a visit to the National Aquarium in Baltimore. Dramatic architecture and bright outdoor graphics invite you to
Over the years, problems arise that are threatening to us and the environment we live around us. Some problems are more serious and threatening than others. Other problems are easier to deal with and are fixed can be easy with easy solutions. One serious problem that has been an issue for many years is invasive species. Invasive species are defined legally in the United States as “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health”
Rescuing the Everglades INTRODUCTION The Everglades, commonly referred to as the "River of Grass," is the largest remaining sub-tropical wilderness in the lower 48 states. It contains both fresh and saltwater areas, open Everglades prairies, pine rocklands, tropical hardwood forests, offshore coral reefs, and mangrove forests. The broad spectrum of wildlife living in the Everglades includes aquatic birds, mammals, reptiles, and amphibians, of which fifty-six species are endangered or threatened
Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (Müller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has been
Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood. In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages. In the Earth’s history, changes have often occurred in the ecosystems. For example, glaciers and the retreat of glaciers cause wide-spread changes. However, although change is a constant in ecosystems, animals and habitats
The Bogus Logic of The Beak People who have served in the Armed Forces may be familiar with the expression, "If you can't dazzle then with your brilliance, baffle them with your baloney." The Beak of the Finch uses such laughable logic, it is remarkable that anyone would believe it. The book does such a terrible job of presenting a case for evolution and history, that the only logical conclusion is that the book's true intent is to disprove it. Jonathan Weiner, The Beak of the Finch:
