Wallace's Flying Tree Frog South East Asia By Landon Batte About Wallace's Flying Frog Wallace's Flying Frog is a frog first described by
Alfred R. Wallace. Wallace's Flying Frog can be
found on the Malay Peninsula and Western Indonesia.
Their large eyes, large eardrums, long limbs, and very
webbed toes are characteristics of this frog. It has loose
skin that allows it to jump from tree to tree, almost as if it were flying. Habitat of Wallace's Flying Frog These fascinating creatures live in the mid- canopy level of the dense rainforests of Malaysia and Borneo. Living in this level of the rainforest is no problem for these frogs. Due to the fringes of skin on their limbs, they are able to glide from branch to branch with ease. They descend to the forest floor for special occasions, such as mating. Rainforests are full of biodiversity, especially in the canopy section. There is a range of plants, bugs, birds, and other things that inhabit the canopy. Wallace's flying frog certainly does live in a very interesting environment. Determining if it's a Wallace's Flying
Frog and its niche At first glance, this frog may look like a lot
of other flying frogs. What makes Wallace's
Flying Frog distinguishable is its larger size,
from 80-100mm; webs are jet black at the base;
large toe pads which help for landing and sticking
to branches; and they have large eyes, eardrums, and long
limbs. This can still be confused with other
species, but the fringes of skin between its limbs
tend to be more orange in color. The niche of
this frog is to keep control of bug populations in its
environment. By eating bugs, this frog is able to
help maintain a good population of bugs. If they
did not, or any other species like it did not, then
the bug population would be too high and would
have negative effects on the environment. An up-close of the frogs' webbed toes The frogs eat bugs as its niche in its environment Mating Habits The mating habits of this frog is interesting. They
use their fringes of skin to safely descend to the
forest floor and mate and lay eggs. However, these
frogs depend on mating and laying eggs in the
wallowing holes of the asian rhinoceros. The asian
rhinoceros population is almost extinct which is
negatively affecting Wallace's flying frog. Genetic Variations There are not any very major genetic variations
among the species; shade of the skin and size of
body, legs, and skin fringes vary. However, if longer
limbs, a larger body, and larger skin fringes can
help these frogs jump even further, then this may
be a very important variation. If the environment
is changed so even these frogs have a hard time
jumping around, then evolving so they have an
easier time is important. They may even need to
become smaller in size depending on what the
change in the environment is like. Even difference
in size, something that may not seem like such a
big deal in this species at first, can be very important. Related Species A closely related species to Wallace's
Flying Frog is the Chinese Gliding Frog.
It is similar to Wallace's Frog as it glides
from tree to tree almost as if flying. It is
mainly green with a white underside, and
are about 4 inches in length. Another closely
related species is Helen's Flying Frog. It also
glides from tree to tree as if it were flying.
They are also green with a white underside
and also seem to have black webbing like
Wallace's frog. Helen's Flying Frog Chinese Gliding Frog Disaster: Human Pollution Rainforests, in which these unique frogs live, are very important to Earth. They do many great things for the world, such as absorbing great amounts of CO2 from the air. However, the carelessness of human pollution and habitat destruction threatens rainforests. When toxic products and waste are dumped into the forests, it has negative impacts; nutrients for plants are lost, erosion occurs, etc. In a place with so much biodiversity, everything is connected with each other. If plants don't have nutrients to grow, then a population will be affected because another population can't complete its niche. All of this can affect Wallace's Flying Frog. If plants can't get nutrients then living in the trees may be more difficult. If deforestation occurs, then they will have almost no where to go. There would be a limited resource of clean water and nutrition in a polluted area, causing negative impacts. Also, depending on what type of pollution it is can cause some sources to be more limited than others. i.e. if it's air pollution then trees and other plants will have less nutrients, but water will still be a resource available. Chinese Gliding Frog There is a difference in color
between these two frogs. These individuals have different sizes and other characteristics. Rhacophorus dennysi Air Pollution Air pollution is the type of pollution that I think could be the biggest threat to Wallace's Flying Frog. When bad gasses get into the air, it decreases the ability for the trees of the rainforests to take in CO2. If plants can't do this properly, then they will start to loose life. If trees start to be affected, then living in the canopy would not be the most ideal place for these frogs. They are well adapted to gliding from tree to tree, but if pollution changes the environment then they will have to adapt to living other places: the forest floor and the water. This... How Will Adaptation Work? Wallace's Flying Frog has great adaptations for living in the canopy region. However, these adaptations wouldn't be very necessary for frogs who mainly live on the ground and in water. How will they adapt to their new environment? Living on land and in the water, they would want to have powerful legs for hopping far and swimming very fast. Frogs that are already larger and have more powerful legs than other individuals will most likely survive. Over time, their larger size and more powerful legs will become a more common trait. Something that may not seem like such a big difference between the individuals of the species can actually turn out to be a big thing. Even something like having a little more webbing can make a big difference; the more webbing the better they can swim. A darker color can also be a trait to better survive. It's darker on the rainforest floor than up in the canopy, so a harder to spot, dark color can come in handy. They would also lose some traits over time. Now on the ground, they wouldn't really have so much need to have extra skin fringes or extra padded toes; they wouldn't be jumping from tree to anymore. Over time, Wallace's Flying Frog could become larger, gain more powerful legs, and become a darker color so they can adapt to their new environment. this larger and more powerful
individual would have a better
chance than the others in their
new environment. Wallace's Flying Frog is now a more darker, earthy color and has more powerful legs that will help it survive better in its new environment. Asian Rhino This... Can cause this. The frog with the larger body and legs will more
likely survive than the others. A darker color will be more helpful
in its new, darker environment.
