Around the world, poison frog populations have been declining due to unknown reasons. Two experiments were conducted promptly in order to find the cause of the disappearances. One hypothesis suggested that the poison frogs are in a decline because of an infectious fungus called chytrid fungus. On the contrary, another hypothesis alludes to the idea that decreasing leaf litter is causing the widespread decline. Although it seems that there are multiple reasons for the decline, it is unquestionable that, according to the data from the experiments, that leaf litter is one of the main components of the decreasing population of poison frogs, having multiple replicates of data is important in finding the answer to the decline, and that there is much more to investigate about this problem. According the data from the experiments, the decreasing amount of leaf litter is a potential threat to strawberry poison dart frogs. This relationship occurs because moist habitats under leaves are essential in keeping the frogs' skin moist. Also, the …show more content…
In the experiment that tested whether leaf litter played a role in poison frog decline, there was ten plots that had no change in leaf litter. The data was fairly consistent until plot number seven appeared to have sixteen frogs in it. This was more than twice of the amount of frogs than any of the other plots with no change in leaf litter. Clearly, this is an outlier in the data and could have thrown off the average amount of strawberry poison dart frogs in leaf litters. If 1,000 frogs had been tested, this outlier would not have made such an impact on the mean. One plot in each condition represents 10% of all the poison frogs that lie in the corresponding treatment's population. This means that out of one million poison frogs, one hundred thousand frogs are being represented in a single
The professor points out that young cane toads and their eggs live in rivers and streams and water flow young toads from one side of the river to the other side. Therefore, the professor adds that even if few of the cane toads could
Why? It’s because, the chemicals goes into the soil and makes runoff from the stormwater, and gets into the water, and pollutes it. The chemicals make the water polluted, which also harms the wildlife. Other things including sediments, dirt, and muck also get in the water
This fungus found on the frogs is capable of moving on its own the fungus generate Microsoft sports with long skinny Tails these poor Pell's themselves through water and can be carried far long distance by streams are in runoffs after rain storms (Kolbert 33). Many since most of them were probably unknown to science (Kolbert p25). Kolbert studied several different theories about and the golden frog species disappearing BD fungus has also since arrived in Panama, from South Africa, and down the eastern coast of Australia, as a crossed into New Zealand, and Tanzania Etc. (Kolbert 30).This Mass extinction of the frog population subsequently shown that BD interferes with the frogs ability to take up critical electrolytes through their skin this is causes them to suffer and heart attack when exposed to light. There has not been no found cure for the BD fungus but know that bleach kills the fungus direct contact to
In this lab we were trying to figure out if Salt Creek and Barker Lake had the correct chemical balances to sustain catfish for the years coming. In order to find this out, we tested the water using a Hach Water Testing Kit. Inside were dissolved oxygen reagent powder pillows 1, 2 and 3 which we added and mixed into our sample water to prepare it for testing. Then we added droplets of Sodium Thiosulphate Solution into the prepared water too see how much dissolved oxygen parts per million were in the water. Our independent variable in this experiment was the 5 different testing sites that we went to for water samples.
Pesticides such as lampricides and chemicals are being used to target invasive species such as purple loosestrife and sea lamprey. Since prevention is not always guaranteed, these lakes should be closely monitored for invasive species and in a case where it occurs rapid eradication should be practiced to prevent their growth and save further
Book Summary In the introductory part of the book, the author defines the word “outlier”. According to the author, an outlier is that person who is different from others. In some chapters, outliers also refers to situations and physical things. The definition provided by the author is the foundation of this book.
It is typically 1.5 to 5 inches in length. This is an issue because it is not native to North America. The treefrogs were brought to North America by ships travelling from the Caribbean. Since there are no predators to the animal the population has been able to spread all the up to North Florida and the Jacksonville region. People have reported that when the Cuban Tree Frogs appear on their property the population of native frogs, toads, lizards, spiders, and insects have severely dropped.
We learn from the individuals introduced so far in ‘Outliers’ that odd occurrences are not random. Whether it’s a Canadian Hockey Team’s high number of players born early in the year or a South Korean airline with a crash rate higher than its competitors, there’s a logical explanation to it. How about migrant Italians of Roseto, PA with above-average health? Who's diets faired no better than their European counterparts in neighborhoods nearby. Further, the successes of Bill Gates, Bill Joy, and other tech moguls, while not obvious, are also explainable.
Correlation isn’t resistant to extreme observations; outliers can have an affect on the
There is only a certain amount of nutrients that the ground supplies for trees, which doesn’t allow every tree to fully grow. The nutrients one tree is using in one area can restrict how much another tree in the same area can grow because of the competition for the minerals. d. They are most likely to be herbivores that feed off of the plant life at the bottom of the ocean because marine producers (seaweed and kelp) grow from the bottom of the ocean, surface marine life would not make good herbivores because plant life (other than algae) is so scarce. e. Insects that are affected by pesticides generally dwell within buildings where small birds that feed on insects can not reach, so the small birds would feed on insects that aren't affected by the pesticide and therefore wouldn’t die from it.
The author enumerates some possible solutions for reducing the number of cane toad, a kind of amphibian native to Central and South America, that was intentionally introduced to Australia to eat harmful insects in that region. The lecturer, however, refutes the proposed suggestions by mentioning some counterclaims, and she believes that they would be unsuccessful and they may bring about some damages to environment. First, the reading asserts that building a national fence would be a practical solution since it prevents the cane toad from entering other new areas like the one that was practiced beforehand. Nonetheless, the professor roles out the probability by mentioning another possibility.
We have learned ever since we were introduced to statistics that outliers don’t just fit in. In Outliers by Malcolm Gladwell, these people gain a new definition: they do fit in. So much, in fact, that people shape their own lives to become an outlier. We idolize them and crave to be as successful as them, while they are really just the same as each one of us. What makes them true outliers is a combination of fate, fortune, and fervor.
An Outlier sounds a lot like an outsider correct, well in my perspective they are one in the same and that is a good thing. The biggest notation I can take from this book is that different is great. In their experiments and analyzations, it appeared to me that those who differed from the majority were more successful. It also reminded me of my freshman Honors Biology class. There was this student that slept basically every day in class and just some how seemed to absorb the knowledge in her slumber.
Dragons have never been considered endangered or even extinct species. They are mainly classified as mythical creatures, legendary monsters, or famous beasts existing throughout the world. Historians, rulers, artists, writers, poets, astrologers, dragonophs, animators, game designers, and even toy makers have been preserving not only the images of diverse dragons, but also details about their names and their incredible transformational powers to hide in obscure places, stay submerged at deep sea levels, soar to great heights, spew fire, and even converse with humans. Although dragons are regarded as rare supernatural beings, there is no scarcity of information about them. Almost all world languages, native American Indian languages as well
Average results are not much reliable in this case, as it cannot explain much about
