Batrachochytrium dendrobatidis

The Poison Darwin Dart frog derived from the joining of a Darwin frog and a Poison Dart frog. It is classified in domain Eukarya because it contains eukaryotic cells, uses the process cell division to replicate, and it is a multicellular organism. It is in kingdom Animalia because it is a multicellular chemoheterotroph and does not have cell wall (Domain Eukarya 1). In phylum Chordata because the Poison Darwin Dart frog contains a notochord, a hollow nerve cord, pharyngeal slits, and a postanal tail (Phylum Chordata 1). In class Amphibia because frogs live in water when they are tadpoles and their eggs need to develop in water and when they grow can live on land. Order Anura is another name that refers to frogs or toads. Where it lives… These new species of frog can be found mostly in South America and live in areas where the climate is warm or cool. The environments they usually live in are tropical rain forests, swamps, streams, or fields. Characteristics These frogs are usually small and can grow from 2.5 to 3.5 centimeters. It can live from the minimum of three years to a maximum of fifteen years. Their head is triangular shaped, has a pointed snout, and a round body. Frogs do not have a tail only in the tadpole stage which allows them to swim around and transport themselves to different parts of the pond. Their skin is the way they use to breathe and manage their body temperature. Because they are cold-blooded animals, they maintain heat by being under the sun and if…

There has been a large reduction in populations due to the destruction of wetlands/habitats, human development, and the pollution of water introducing climate change and infectious diseases (Rollins-Smith 111). Recently, there have been three pathogens associated with amphibian declines globally: ranaviruses and two species of chytrid fungi from the genus Batrachochytrium (Rollins-Smith 113). “Ranaviruses are aquatic DNA viruses that target a number of cell types causing necrosis and…

The Panamanian Golden Frog proves that size does not matter. The diminutive size was countered by potent defense, as the poison in just one of the frogs could kill about a thousand normal mice (Kolbert, 2014). In addition, their presence has transgressed the animal kingdom as it has left a remarkable impact on the town of El Valle de Antón in Panama. The Panamanian Golden Frog has become a cherished symbol synonymous in the area, as it is associated with good luck and fortune (Kolbert, 2014).…

to amphibians, chytridiomycosis is a fatal skin disease (Berger, 1998) caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd), and is only lethal towards post-metamorphic frogs (Longcore, 1999). With a global distribution of approximately 1000 described species, Batrachochytrium dendrobatidis is phylogenetically distant from other chytrid types, suggesting the recent evolution of the fungus (James, 2006). Lips (1998) provide a description of an explained, abnormal decline in the…

He took samples from frog skin and ran it through an electron scanning microscope. The results brought in information on a fungal infection from a fungus group called Chytrid. The weird thing about this discovery is that this fungus has never been seen before and they can only be found deep underground or in treetops. So they had to create a whole new genome for it. They named it Batrachochytrium Dendrobatidis or Bd. Tests were run on this fungus, and when it was exposed to poison blue dart…

and campgrounds. The rise in temperatures in the Rocky mountain national park in the 20th century. Invasive Species: Cheat grass, or Bromus tectorum, is an invasive plant which is indigenous to Europe, Northern Africa, and Southwest Asia. It restricts the growth of other plants and grasses by dropping its seeds which germinate before the seeds of indigenous plants can. Cheat grass in the Rocky Mountains increases the chance and intensity of fires because its seeds are dropped earlier than…

animal survives, they pose a serious threat to existing populations. Animals in captivity, especially those in animal testing, may have foreign diseases to which wild animals are not immune. If the disease is contagious, it can quickly spread throughout the population that the reintroduced animal encounters and possibly other populations of different species. These diseases may wipe out entire populations, which is counter to what those who advocate for species reintroduction strive for. A study…

range and climate change. Climate change can also influence life cycles of hosts, pathogens, and vectors. For example, Aedes mosquitoes capable of carrying the Rift Valley Fever virus lay eggs in floodwater, which are capable of surviving through dry spells and hatch the next time it rains. As the IPCC has reported, precipitation is likely to increase in the future, which could result in shorter, more frequent endemic cycles. The review also stated that environmental changes could affect the…
