Batrachochytrium dendrobatidis

The ability of Batrachochytrium dendrobatidis to grow in amphibian and non-amphibian hosts such as zebrafish (Liew et al. 2017), cray fish (McMahon et al. 2013), reptiles (Kilburn et al. 2011), and waterfowl (Garmyn et al. 2012) is well documented. There are also records of the survivability of B. dendrobatidis in the sediments and water (Kirshtein et al. 2007). In this study, we showed that B. dendrobatidis has the potential to form a biofilm which ensures its survival in the environment without

invasive species. However, there may be a way to cease the harm caused by invasive species using genetic modification. One example of an invasive species is Xenopus laevis, or the African clawed frog. These frogs carry a fungus called Batrachochytrium dendrobatidis. Chytrid fungus infects amphibians with chytridiomycosis by attacking the part of a frog’s skin that contains keratin. Frogs use their skin to

Not all amphibians are affected by chytrid fungus the same way. Susceptibility of B. dendrobatidis in amphibian hosts depends upon the particular species immune system make up; some species have antimicrobial peptides and mutualistic bacteria that fight epidermal infections (Stockwell, Storrie, Pollard, Clulow, & Mahony, 2014, p.397). And there

There is a deadly fungus called Batrachochytrium dendrobatidis, Bd for short, that has been wiping out populations of frogs all across the world. Bd has caused dozens of extensions over the past four decades and leaving behind very few survivors. Also in the 1980s the frogs faced a similar problem with this chyrid fungus that wiped out four frog species. However, there are two frogs, the whistling tree frogs and the alpine tree frog, that are doing better than scientists predicted. The whistling

Our planet is currently suffering its Sixth Great Extinction, a time in which a various species of organisms are disappearing at an unprecedented rate (Collins and Crump xv). The most rapidly disappearing groups of organisms are amphibians, and over 200 of these species have been brought to extinction since the year of 1970 (Save the Frogs). One of the largest causes of their rapid declines is the spread of the lethal disease chytridiomycosis, a fungal disease largely spread by humans (Whittaker

Agalychnis callidryas, or the red-eye leaf frog, is one of the most recognizable frogs in the world with its dorsal, lime-green skin, lateral cobalt-blue stripes, orange toes, and large red eyes (Ge et al. 2014). This Hylidae-family frog typically lives in humid, tropical rainforests in Central America (Boman 2002), and has a high population density in the lowland forests of Costa Rica (Ge et al. 2014, Wang et al. 2015). Since this frog belongs to the class Amphibia, its skin possesses many important

Cloud forests are very diverse ecosystems, but very vulnerable to disturbances. Although these forests are patchily distributed across only 1% of Earth’s landscape, they support high levels of endemism, which requires a delicate balance of environmental and ecological factors (Doumenge, Gilmour, Pérez, & Blockhus, 1995). However, increasing technology and human population growth have initiated many ecological disturbances worldwide (Fabry, & Lapointe, 2015). Cloud forests are particularly susceptible

measures are not taken, the loss of biodiversity would be catastrophic. Chapter one begins by describing the golden frogs in the town of El Valle de Antón, and how they were beginning to disappear. The frogs disappeared due to a fungus called Batrachochytrium dendrobatidis. This fungus has spread around the world at a lightning-quick rate, killing all sorts of amphibious organisms at an unnatural rate. The cause of the rapid spreading of the fungus has been theorized to be due to humans inadvertently spreading

The corroboree frog is a native Australian frog found in the mountain ranges of the Kosciusko national park. There are two variations of the frogs inside the species these include the northern corroboree frog (NCF) and the southern corroboree frog (SCF). Historically scientist named these frogs based on where they were found in the Kosciusko national park. The NCF lives in the northern parks of Kosciusko national park, Namiadgi National park and Rinabella national park, as seen in the image below

Our species changes the world every day. We are Homo sapiens. In our past we have forced species into extinction through hunting. We knowingly and unknowingly transport non-native organisms around the world. Some of those non-native organisms we introduce become invasive and create a hazard to a regions native species. As humans we have managed to change the climate of the entire planet and even though the climate change has been slight, we have come to learn that an increase of a few degrees can
