Ecological Facts
APES 2015 - 2016
Fact # 1 - Tarsiers
Habitat
 Mostly found in the regions of South East Asia where
there is high precipitation and therefore abundant wide
leafed trees where they commonly dangle.
Habitat
 Tarsiers always cling to trees 2 – 3 meters and more above
ground to avoid predators, to intercept preys and the fact
that these organisms cannot walk – they can only hop due to
the anatomy of their hind legs.

Population Decline
Logging  Habitat Loss
 Higher exposure to Predator
 Lower food gain
DEATH
 Stress
 Suicide
 Low population
 Less group protection
In case of an attack by a predator on any one
of them, all the tarsiers nearby come together
to take on the predator.
Fact # 2 – Panda Bears
Habitat
 Giant pandas live in large bamboo forests on humid and
relatively high mountains — about 1,200 to 3,100 meters
(4,000 to 10,000 feet) above sea level.
 The elevation where they thrive supports the 42 different
species of bamboos that Giant pandas strictly and
selectively eats.

Fact # 3 – Bee
Hummingbirds
Habitat
 Primarily found within mature forests and at forest edges,
where there are plenty of bushes, lianas and epiphytes. It is
also known to inhabit mountain valleys, swamplands and
gardens, and is occasionally recorded in open country.
 They are named as the smallest birds in the world (females
– 6.1 cm, males – 5.5 cm) and depend only on the nectar of
flowering plants (angiosperms).
 These birds DO NOT migrate because of
their strict diet which is determined
by the amount of rain and temperature.

Bottom Line?
 The most fascinating organisms in this planet are highly
dependent on ABIOTIC factors.
 Humans generally messes up this Biotic – Abiotic
dependence/interrelation.
Your Task:
 Refer to your textbook, pages 89 – 90
 Write your answers ONLY on a separate sheet of paper
 Do/Answer the following:
1. What is a certain species’ niche?
2. Describe as detailed as you can, your own niche.
3. Justify whether you are a Generalist or a Specialist species.
4. Read ‘Cockroaches: Nature’s Ultimate Survivors’ – pg 90, then
answer the Critical Thinking at the bottom of the
“spotlight” box.
(Continue on the next slide)
Your Task: (continuation)
5. Explain by citing evidences (from the text) why it is most
likely that cockroaches will thrive longer and survive in a
polluted wasteland such as the planet Earth than Homo
sapiens.
6. Summarize cockroaches niche.
Note: Please write clearly. Do not proceed to Period 2 activity
until you finish this task!
