Convict cichlid

choose the way they mate, depending on what is best for the species, and there can be a mixture of the species for the intermediate phenotypes versus the extreme phenotypes (Ng & Williams, 2014). In each of the three studies the species (the convict cichlid fish (Amatitlania siquia), bridge spider (Larinioides sclopetarius), and dioecious mangrove snail (Littoraria ardouiniana))

young compared to the surrounding lakes in the region. Despite this, the haplochromine cichlid fish that inhabit this lake have shown rapid evolution. The lake was formed by a combination of tectonic movement and river water reversal of an “ancient drainage system” in the Pleistocene. The lake is also shallow compared to others in the area (a maximum depth of 69 meters), so it is unlikely that the resident cichlids could have survived in pools during the lake’s desiccation in the late Pleistocene (Coyne

Phenotypic Plasticity Phenotypic plasticity is when a genotype of an organism displays different phenotypes due to the conditions of the environment. It is important to understand why different organisms respond differently to changes in the environment and the ways they adapt to these changes. This paper focuses on whether these adaptations are due to either phenotypic plasticity or local adaptation. Since nothing is ever perfect, the paper also concentrates on the constraints of phenotypic plasticity

increasingly alienated population to form in the U.S., which can be broadly classified in the dual areas of lasting effects and impacts to the family unit. First, the lasting effects of high incarceration rates are that they impact the rights of the convict, particularly African Americans. For example, noted civil rights attorney Michelle Alexander posits that the long term effects of mass incarceration operate to deny black Americans the future right to volte, the ability to obtain public benefits

Setting Up Your Aquarium Aquarium Size Matters When it comes to keeping African Cichlids you want to make sure that you have an aquarium that is big enough for the fish. A basic 20 gallon/~75 liter tank is not quite big enough to successfully keep your fish. While I have read that a 25 gallon/~95 liter tank is sufficient, I would not go with anything less then 29 gallons/~110 liters. The first cichlid tank I setup over 20 years ago was a 30 gallon/~113 liter flat back hexagon tank. The aquarium

Fishkeeping. Often portrayed in the media as one of two extremes: incredible, aquarium-worthy tanks with intricate setups and many species, or a lone goldfish in a bowl. While neither are particularly accurate, it shows what the general, uninformed public sees as fishkeeping. In reality, there are two types-freshwater and saltwater, with each requiring commitment and care. There are, however, major differences. Freshwater tanks require far less maintenance, and are nowhere near as delicate as a saltwater

Ultrastructural data on the spore of Myxobolus dermatobius Ishii, 1915 (Myxosporea: Myxobolidae) infecting eye of Nile-tilapia (Oreochromis niloticus) in Egypt NOSSEUR M . EL-SAYED Department of Parasitology , Faculty of Veterinary Medicine, Zagazig University, Egypt.

chance of success for inmates once they have finished their sentence, and this keeps them from further burdening an already straining system. The Bureau of Prisons spends a large amount of money housing, feeding, and attempting to rehabilitate convicts. Given the current laws in place, it is hard to offset the costs required to run those prisons. Residents participating in halfway house programs are extremely low cost when compared to those inmates residing in the prison system. The differences

Returning Ex-Convicts exiled into our Society Imagine having a next door neighbor is an ex-convict; which is defined as “a former inmate in prison” (ex-con). According to Bonita Veysey, the editor of How Offenders Transform their lives ‘‘This year, over 600,000 people will be released from prison, and many millions will be returning to their communities from shorter stints in jails’’(2). With this statement, would you feel comfortable continuing to live in your neighborhood? Or immediately pack

Speciation and Evolution of Cichlids in East Africa Dr. Hoeh WIC Matthew S. Holcomb March 2, 2015   Introduction The East-African cichlids are a rather interesting and diverse group of fish, and have caught the eye of many scientists particularly because of the speed, diversity, and convergent patterns of their radiation (Yong-Hwee et al. 2012). For instance, there are 500+ species in just one lake, Lake Victoria, and an estimated 2,000+ species in total. The fish in lake Victoria, which is estimated
