Biodiversity Writing Assignment
California Red- Legged Frog The California red- legged frog (Rana draytonii) was the threatened species and was found in the western United States. More than seventy percent of California red- legged frogs have been eliminated from their former extent. Nowadays, this breed is still popular in the Bay area but isn’t much like before (USFWS 2002). In nature, California red- legged frogs are 1.5 to 5 inches in length. Adult females are much longer than males. Their legs are marked by a reddish color. Their back is brown, gray, olive, or reddish brown, marked with black dots (Stebbins 2003).California red-legged frog mates from November to April. Egg masses, which contain about …show more content…

    Why Is The Cane Toads Problematic

    Nobody would have expected just how much damage a palm sized toad could have done. Back in 1935, entomologists were trying to come up with a solution to the beetle infestation which caused the depletion of the sugarcane crop. Reginald Mungomery thought he had the solution by bringing in the cane toad, but eighty years later ecologists are still trying to fix the problem he caused. Mungomery's theory worked in Hawaii with the toads eating the beetles. Unfortunately, the cane toads in Australia ignored them and just lived and reproduced at high rates.…

    Pacific Tree Frog Research Paper

    Frogs and other amphibians are important for several reasons. One reason is that they are an integral part of the food chain, as they serve as both predator and prey (What Do Frogs). Without them, the ecosystems they live in would suffer. For example, frogs feed on pests, such as mice or insects, which infest human homes and consume crops. Without frogs and toads to feed on them, the populations of such pests would grow rapidly. Many of their prey even spread diseases, like mosquitos which spread malaria, so frogs play a direct role in keeping humans healthy. Tadpoles, juvenile frogs and toads, clean waterways by feeding on algae, which cuts down on costs that would otherwise be needed for water filtration (Why We Must). Additionally, frogs also serve as prey for a variety of organisms, from predatory birds, fish, and snakes, to larger insects, other frogs, humans, and more. If frogs die out, all of their predators would have to cope with a lack of food sources as well (What Do Frogs). Furthermore, because amphibians live in both water and land, they play key roles in transferring nutrients between the two. Without them, all organisms in their environments would suffer. Food webs such as this are simply too interconnected for the loss of one creature not to affect the rest, especially not creatures as vital as amphibians (Amphibian…

    Deformed Frogs in Minnesota

    Deformed Frogs in Minnesota

    In the past few years, citizens of Minnesota have discovered deformed frogs scattered throughout the state. There are many speculations as to how the frogs got such deformities. Some scientists believe that its something in the waters of the Minnesota wetlands, other factors could be parasites or ultraviolet radiation. Minnesota is not the only location in the world that has reported deformed animal sightings, but almost three-quarters of the deformed frogs were reported in Minnesota. This is not necessarily because Minnesota contains the most deformed frogs, because scientists are unsure if that is true. Residents of Minnesota are most aware to the problem, so they are basically looking out for the frogs. Deformed frogs are most commonly missing limbs, have extra limbs, or have some bent limbs. Also, there are internal deformities that one would not be able to tell just from looking at the frog. These include digestive and urinary problems, and a slow ability to eat, avoid predators, and move. Because of this most frogs do not survive the winter, and if they do, deformed frogs do not advance on to a second year of living. Deformities do not occur in all frogs, the most common frogs with these malfunctions include the wood frog, American toad, and the northern leopard frog. Since deformed frogs have been found in ponds and both the urban and rural parts of Minnesota, scientists have concluded that well water can produce such malfunctions. Several tests have been preformed on the water that Minnesota residents are drinking and nothing has been found. The Minnesota Pollution Control Agency and the National Institute of Environmental Health Sciences have been performing tests to help solve the problem of deformed frogs in Minnesota.…

    Horned Toad

    The common name “Horned Toad” for Texas Horned Lizards comes from two of its most prominent physical characteristics. Phrynosoma cornutum has two large horns on the center of its head accompanied by lots of smaller horns around it (Bockstanz 2016). It is commonly called a “toad” due to its short flattened body and short legs (Seymour 2016). Spines are found all over the body of the Texas Horned lizard and down its tail (Seymour 2016). Sexual dimorphism between males and females can be seen in two ways, body size with females being larger and the presence of femoral pores on males (Figure2). It has been shown that southern populations of P. cornutum are on average larger that northern populations (Henke & Montemayor 1997). In southern populations…

    California Red Legged Frog

    Another reason the frogs population began to rise again was because they finally figured out staying in large groups helped their survival. Like many other endangered species there is always one rule of survival that always seems to be applied in every environment and that is either adapt or die off and it seems the California red legged frog realized that if they want to stay alive that they need to be in packs and also the land contribution helped the survival of the frogs to where they don’t die off and increase their population, even though some frogs became extinct from not knowing to adapt to the situation.…
