Matrotrophy is the alternative reproductive method to laying shelled eggs in reptiles. With this maternal strategy, females can supply their unborn offspring nutrients from their own bodies via a placenta for their entire gestation period rather than relying on egg nutrient stores and external incubation (Itonaga et al. 2012). Squamates are known to contain several species that give birth to live young, contrary to the usual shelled-egg method of most other reptilian taxa such as the Crocodilians

The cane toad, also known as rhinella marina, got its bad reputation soon after being released into the Australian ecosystem in 1935 with the expectation that it would control the destructive cane beetle population. However, instead of controlling pests, the cane toad became a pest of its own. About 3,000 cane toads were released in the sugarcane plantations of north Queensland in 1935.

Cane toads, Cane toads earned their bad reputation shortly after being released into the Australian ecology in 1935. They were brought their in order to control the cane beetle population. They turned out to be failures at controlling beetles, but remarkably successful at reproducing and spreading themselves. Cane toads forage at night in a wide variety of habitats. The toad is a ground-dwelling predator, primarily eating terrestrial and aquatic insects and snails. Cane toads need constant

The Everglades is a vast region that stretches from the Kissimmee River to Lake Okeechobee and is filled with a unique and world-famous ecosystem that is exclusive to the rest of the world. It is located in southern Florida and takes up 1.5 million of the land. While there are many diverse species, there are around 500 human inhabitants. This region is one of the largest wetlands in the US and the only existing Everglades in the entire world. Because of this and other pressing factors, about one-fifth

The Shortland Wetlands have became one of the most popular and well-known attractions in Newcastle for its extensive wildlife, many activities and intensive research on conservation of many topics.

There are also other varying biotic factors such as the diversity and quantity of the plants and animals found there. (Tpwd.texas.gov)

My job is to care for the animals in the "Animal Museum" and teach the public (usually toddlers) about them. It was never to feed the large birds of prey that live outside. Staff members are responsible for that, but my supervisor had told me that everyone was too busy running various programs. She herself needed to be somewhere, so she asked me to feed the GNC's

A controversial topic commonly debated among society is the construction of coal mines. Although they potentially contain great economic promise and access to more resources, they also harm the surrounding environment and increase carbon dioxide emissions. A specific example of a possible excavation site is the Galilee Basin, located in western Queensland. The Galilee Basin is an untapped coal reservoir that spans across 247,000 square kilometres of land and is home to five mines approved for

Textbook Answers 1.The cost of sexual production; a. Asexually reproducing populations grow at twice the rate of sexually reproducing populations. This is because every asexual organism has a potential of giving birth however, in sexual populations the male gender cannot reproduce. b. There can be a genetic cost; by reproducing sexually, successful combinations of genes have to divide. c. Sexual requires courtship and mating; spending energy searching for a partner increases the risk of injury
