Fragmentation Of The California Red Legged Frog

Florida has more introduced species of reptiles and amphibians in the wild than anywhere else in the world, causing the native populations to become unbalanced (University of Florida, 2012).

The conquering and development of natural land has in the past, been seen as a mark of human civilization. In the United States, our progress is often measured by growth and development, but should this be re-examined? There are many opinions on the subject of urban sprawl and its effects on wildlife, but one thing is for certain, we are expanding. From 1955 to 2005, urban and suburban areas grew by 300%, however, the population only increased by 75% over the same period (Ewing, Kostyack and Chen). According to NatureServe, a non-profit conservation organization, urban sprawl threatens one of every three endangered species in the United States. NatureServe’s analysis states, “rare and endangered species data shows that three-fifths (60

    Recently, an invasive and lilliputian frog has had a detrimental effect on the Hawaiian environment. Originally from Puerto Rico, the amphibian arrived in Hawaii and spread like a plague. Such a small frog cannot have that big of an impact, right? Wrong. The Coqui frog is a damaging invasive species of the Hawaiian islands due to its lack of natural predators and adaptability, dangerous eating habits, and its easy distribution among the state.

The future of California is pretty good, for the state is projected to see growth in almost every sector of the economy as well as the population, but there are many concerns that must be addressed first in order to see California’s growth come to fruition. International trade and business is one of California’s largest industries and it’s expected to continue increasing, for many emerging economies are also located off of the Pacific Ocean. Growth in the economy is good, but requires resources that California has a limited supply of. The main resource California always needs is water, since most of the state’s population resides in the southern regions, which are arid and receive minimal precipitation annually. The state is planning on improving efficiency and the aqueduct system to increase the water supply while decrease the environmental effects California’s aqueduct’s have on regions like the San Joaquin River Delta. For many years California has been considered a very liberal and left state, which is due to the fact that the state has the toughest environmental legislation in the country. With such strong legislation ensuring the protection of the environment California has become a model state in the fight against climate change, and must remain vigilant for there are numerous species endemic to the state that are found nowhere else on the planet. Though there are numerous other factors’ affecting California’s future these are some of the most interesting areas to

The importance of El Valle De Anton spurred the movement to create systems to preserve frogs worldwide. In Panama a town name El Valle De Anton once deeply respected their golden tree frogs, and ironically they were not disturb when the frogs started disappearing. When the corpses started to pile up, the scientific community began to become concerned and began an effort to preserve the golden frog species and what they found was that frogs from around the world had been plagued by Batrachochytrium dendrobatidis-batrachos (or “Bd” for short). This plague is very hard to stop, as we cannot purge the entire planet of the disease, and the plague spreads incredibly quickly.

The Florida Everglades is the state’s most highly visited park in the state. The Everglades is also home to thousands of animals, reptiles, and plants. Many tourist travels just to get a glimpse of the many exotic reptiles. Although, the Everglades is very beautiful it’s also one of the most endangered parks in the state. The park is endangered from humans and land developments. The state has laws imposed to protect the everglades. In order for people to save and protect the Everglades there are things we have to do on part. Throughout this essay I will go into depth about the different species, human threats, and what we can do to protect one of our

Which amphibian has red eyes, yellow feet, and looks like a leaf? Red Eyed Tree Frogs of course! Because Frogs are amphibians, they spend most of their time in water or wet places. Interestingly, Female will lay their eggs in water, when these eggs hatch they become tadpoles. These baby frogs have many stages such as, developing back legs, growing front legs, becoming a juvenile frog, and finally losing its tail and becoming an adult. Red Eyed Tree Frogs Wake up at dusk and go on the prowl for insects and fruit, which are its main diet. Also, when red eyed tree frogs sleep, they curl their feet and shut their eyes, they look exactly like a leaf, this helps from camouflage from predators. These loveable leaping

Water resources in the state of California have deteriorated drastically as a result of the current drought event in the west coast of the United States. This has resulted in insufficient supplies of water to residents of southern California, as well as the devastation of wildlife and aquatic ecosystems that are characteristic of this area. This policy analysis will provide the context of the issue, as well as possible solutions, followed by a proposed policy plan to reach the policy goal of equitable and reliable water allocation in the state of California, drought resilience, as well as restoration of the destroyed ecosystems.

In 2012 and 2013 Klamath County on the Southern Oregon border declared a drought in April, after a string of fortunate years of heavy rain and snow. In 2014, a drought emergency was declared in February, two months earlier than in 2013, and in 2015 drought was again declared for the county in April( United State Geological Survey 2015). These successive drought declarations are not surprising to anyone who was following the Western water crisis during those years, where the governor of California declared a state of emergency and urban Californians were mandated to find ways to cut their water consumption drastically . In 2012, 10,000 avian mortalities were reported in the Klamath Basin National Wildlife Refuges because of the shut off of water facilities that support wetland habitat for migratory species (Learn 2012.) During those dry years, an article titled Birds are Dying As Drought Ravages Avian Highways ran in National Geographic, featuring Lower Klamath National Wildlife Refuge and putting the struggle of its bird species in a regional context, as long distance flyers found fewer and fewer refuges with the water resources to maintain them( Kay 2015). It was these shocking statistics that first attracted me, as a birder, to the basin as an area of study. However, as I began to wade into the history of the basin and its complicated local politics, I soon realized that I could not disentangle the issues experienced by wildlife and wildlife managers in the

My trip to the La Brea Tar Pits, taught me of the biodiversity that was within California, from the Columbian Mammoths, Shasta Ground Sloth, Dire Wolves, and Sabretooth Cats. The museum emphasized that most of the extinct animals that were on display were extinct due to climate change or hunted by the earliest tribes throughout California and North America. The museum points out that most of these animals were large, but doesn’t show the reason as to why the larger animals went extinct, but the smaller animals survived the extinction. The museum also mentions that night-stalking animals weren’t found in the pits as during the cool temperatures throughout the evening would solidify the asphalt. This extinction was known as the Pleistocene

The mountain yellow-legged frog is declining due to the introduction of trout, contaminants, increased levels of ultraviolet radiation, and the fungal disease, chytridiomycosis. David Bradford, one of the first witnesses to the decline in the late seventies, noticed the species dropping because of the red-leg disease. Because this is a secondary infection, the frog’s immune system was weakened before the disease became existent. The chytrid fungus was first cited in the Sierra Nevada in 2001, brought here from African clawed frogs, but studies have suggested that the disease has been evident since the mid-‘70s. Nearly three decades later, the mountain yellow-legged frog is still declining. Currently, with a ninety-eight percent decline, there

Chapter One details the ancestry of frogs and examines the timeline of amphibians on Earth, as well as the increase in frog extinction rate. Kolbert argues that the observed extinction rates which are exceeding expected background extinction rates suggest that catastrophe is ahead for Earth. Humans are key to the extinction of Panamanian frogs due to their spreading of the Chtrid fungus, which is not native to Panama. Thus, Kolbert sees humans

California’s diverse ecosystems will collapse because the lack of freshwater will no longer be able to preserve life. In the PPIC Water Policy Center’s study “What If California’s Drought Continues?”, the authors note that, “The most acute and severe impacts of this drought so far are on California’s freshwater habitats and forested lands and on the biodiversity they support” (Hanak, et al.). California’s wetland

The Rana pipien is a frog more commonly known by the name Northern Leopard Frog. They are characterized by dark spots on their dorsal side and dorsolateral folds and considered medium sized. This strong jumper is difficult to catch during the day. It emits startling “warning screams” when jumping into the water and when grabbed. The frog may also release urine to discourage potential predator and reduce weight for jumping. The Rana pipien eats a variety of invertebrates. During winter, they often spend it under under submerged logs or rocks in small streams or marshes where large numbers may congregate.
