Reptili Appropriate Sexual Selection In Reptiles
Sexual Selection in Reptiles
Turtles, crocodilians, tuataras and squamates, which include the diverse forms of lizards and snakes, are included in the group called Reptilia (Townsend et al., 2004). They are ectoderms and their sexual behavior and mating characteristics have been widely studied and many theories and interesting features have been documented over the years (Martin, 1994; Shine 2003). According to Uller and Olsson (2008) the reptiles have a unique characteristic regarding their sexual selection and mating characteristics, called the post-copulatory sexual selection. There are two important aspects related to post copulatory sexual selection, they are

The reproduction cycle in turtles and lizards vary between weeks to years (Pearse and Avise, 2001). Further, the different components and stages involved in the reproduction process in reptiles have temporal differences. According to Aldridge and Duvall, in reptiles the production of sperm, insemination and fertilization occur separately and are divided by long intervals. This mode of reproduction seems to have vital implications in the evolution process of sexual traits of male and female reptiles, including the selection of storage of sperms and
Shoultz And Russell Button Reptiled Case Summary
224 Words | 1 PagesSteve Shoultz and Russell Button Reptiled this case from top to bottom. Despite stipulated liability, minor car damage, lapses in treatment, inaccurate medical records, and a difficult witness prep; Steve and Russell were able to use the Reptile to convey the hypocrisy and betrayal their client suffered at the hands of their own insurance company. We found out halfway into the article that Steve and Russell decided to forgo $40,000 of the client’s past medical bills. This is in a case where the Plaintiff’s son who was in the strike zone of the impact walked away unscathed. The client walked away unscathed, but for anxiety and pain and suffering.

Without reproduction, life on earth would be terminated, every species would have been extinct by now. It is also said that reproduction is the basis and purpose of all life (Savage, 2016).For a species to continue to exist, it must reproduce.
Elizabeth Roberts God's Laboratory Summary
987 Words | 4 PagesA similar phenomenon was explained in Emily Martin’s The Egg and the Sperm. She discusses how “Western science” explains reproduction in a culturally constructed fashion. The language used to describe gametes and other sexual organs ultimately depicts sperm as “active” and “strong” in contrast to the egg being “passive” and “dormant” (Martin 489-450). The language used by scientists to describe reproductive organs is not chosen to satisfy religious beliefs, but analogously the language represents stereotypical male-female roles. Both cases show how “biology itself is shaped by historical and material processes” (Roberts 115).
Dr. Olivia Judson Book Report
1349 Words | 6 PagesFemales invest more and make few large, expensive eggs. For example, when a male honeybee reaches his climax, he explodes, his genitals ripped from his body with a loud snap. In Chapter 2 of the expense is damnable, almost all individuals of C. Elegans are female hermaphrodites, and a small minority, around one in a thousand, are certain true males, Based on XO sex alles (Hermaphrodites have XX) this would conclude that when self-inseminated, a common worm would lay birth to 300 eggs. In Chapter 3 Fruits of knowledge, this chapter shows the main importance of what are the important female roles when it comes to sexual reproduction. Females in many other species insist on trading sex for food, but in this situation, in species where females swap sex for food, loose females typically eat better and have more offspring.
Glass Frog Research Paper
817 Words | 4 PagesWhen Glass Frogs mate they do it after a rainy season or on a day that is foggy and rainy, They only mate in trees and not on the ground. When they are on the ground they are either meeting with a mate or the female is calling for a mate in a loud croaky sound, After a female has found a mate they then head to the tree to continue the circle of life. (Soft Schools). When mating season comes they only mate at night and the male glass frog chooses the site to mate in the tree, Female is the one who calls for the male to mate with later on. Once they are up in the tree and begin to start amplexing together they can take up to twenty to thirty hours together amplexing in the tree, after that process the to develope the tadpoles can take up to two to three weeks.
Salamander Herping Research Paper
624 Words | 3 PagesIt was the day after a large downpour in Boone, NC and a student in a Herpetology class offered through Appalachian State University’s Biology Department decided to lead a group herping, searching for amphibians and reptiles, in the woods near Hebron Rock Colony. We left at 9 p.m. to drive to the trail and from there, we began to scavenge the side of the road for native species of salamanders. With head lamps and aquarium fish nets, we began to head downhill to a small stream. The proper way to herp is to go at night while it is dark, cool, and wet. It is ideal to go herping immediately after it has rained because salamanders are more likely to be found outside of their burrows because their skin will remain moist in wet conditions.
Leatherback Sea Turtle Research Paper
527 Words | 3 PagesFor this assignment, I chose to research the migratory patterns of one of the largest reptiles on Earth, the Leatherback sea turtle Dermochelys coriacea. The average adult leatherback turtle can weigh up to a thousand pounds and measure from 4-8 feet in length! This great size allows them to tolerate cooler water temperatures than any other sea turtle. D. coriacea have the broadest distribution of all sea turtle species and they can be found throughout the Atlantic, Pacific, and Indian Oceans. This large range is due to the migratory habits of the leatherback turtles, which are pelagic wanderers that swim great distances to tropical and subtropical coastal regions of the world to feed, mate, and nest.

They are called Red Ear Sliders because the have a red stripe going across the side of their head.
Pluton Research Paper
1202 Words | 5 PagesThis freaks Elita74 out. How could this happen, what went wrong? She blames the horrific result on the female’s womb, “there must be something wrong with your womb”. She tried the process again on another female and yet again the same thing occurred. She soon realizes that it is unsafe to have the females be unconscious for such a long period of time every time they ingest one of the eggs; and it is also unhuman to have half human-half frogs.
Horned Lizard Life Cycle
260 Words | 2 PagesThe life cycle of the horned lizard is common to many retiles. Mating begins in late April peaking in June and stopping in July. The type of horned lizard determines if they lay eggs or have live births. The Texas Horned Lizard normally lays eggs. If they are laid they are buried in the sand a few weeks after fertilization where they require an additional few weeks for development prior to hatching.

The Puerto Rican Frog
1008 Words | 5 PagesUnlike other frog were they go thru a free-living tadpole stage, the Puerto Rican Frog is bypassed during development, allowing for the eggs to be laid in dry areas without the needs for standing water. Eggs hatch within 8 weeks reaching reproductive maturity approximately within one year. The genus Eleutherodactylus developes an egg tooth to free the young froglet from the egg.

Essay On Sexual Reproduction
1000 Words | 4 PagesSexual reproduction is most common type of reproduction among the plants and animals. They are of following types; 1) Syngamy: The fusion of gametes takes place completely, if male and female gametes are produced by same cell or organism and both gametes fuse together to form a zygote, this is called as Autogamy, paramecium is its example. Another is Anisogamy in which some organisms produce two types of gametes. Both types of gametes differ from each other in their shape and size and are known as an isogametes or heterogametes. Male gametes are motile and small in size and are known as micro gametes.
