Tropical Deciduous Forests Video Lecture - Class 9

[Music]
tropical deciduous forests also known as
Monsuno forests are found in a belt
along the equator between the tropics of
cancer and Capricorn as well as the
humid subtropical they are also found in
parts of Africa India South America
Central America and small islands in the
Pacific tropical deciduous forests
experience eighty to ninety percent
humidity throughout much of the year and
the average temperature is thirty
degrees Celsius year-round one of the
most defining characteristics of Monsuno
forests is their seasonality as
temperatures begin to warm the
Intertropical Convergence zone shifts
resulting in a period of high
precipitation in those regions in the
winter if the ITCZ changes again and
this results in a period of china's
during this dry period many trees shed
their leaves as an adaptation to
conserve water when most people think of
a monsoon they think of a torrential
downpour of rain but a monsoon is
actually a shift in the direction of air
masses during the summer maritime
equatorial and tropical air masses
travel from the ocean onto land as the
temperature rises when the air masses
arrive on land they are lifted by either
convection or convergence of air which
leads to precipitation particularly in
India orographic uplift is a large
factor in promoting rainfall as air
travels to India is uplifted by the
Himalayan mountains causing cloud
formation and precipitation in the
winter high-pressure zones may inhabit
the area and inhibits most precipitation
causing a period of jealousy due to the
dry season tropical deciduous forests
have a lower biodiversity than tropical
rainforests but they'll let that fool
you
tropical deciduous forests can have up
to 200 different species in one hectare
the dominant vegetation that occupies
tropical deciduous forests are called
rain green fauna because trees leaf out
during the first heavy rains following
the dry season and display a lush green
growth typically Liana's epiphytes a
teak bamboo and other ferns and shrubs
consist of the dominant vegetation in
this region due to the lack of
precipitate
the forest is not as dense as a tropical
rainforest this means that trees do not
grow as closely together and therefore
continuous canopy is never developed
this allows more light to reach this
forest floor or a dense undergrowth can
begin to form these forests are also
home to monkeys deer large cats such as
the Bengal tiger parrots and other
various birds and insects many trees
such as the cheek tree have developed
numerous methods to conserve water as a
result of the dry season a large
majority of trees drop their leaves
because having leaves is very costly
when water resources are limited a large
amount of moisture can be lost through
evaporation so the trees lose their
leaves in order to conserve as much
water as possible another adaptation
that the vegetation is owner ghana is
the development of waxy surfaces and
drip tips on the leaves of many plant
species found in monsoon or forest this
promotes drainage when precipitation
levels are high and prevents the growth
of bacteria many of the trees are also
adapted to wild wild fires as well the
bark on the majority of the trees found
in tropical deciduous forests this
thicken course and is able to withstand
extreme heat from wildfires and the
roots of most trees extend deep into the
soil in order to have access to the
groundwater much like the rainforest
habitat fragmentation is a large issue
that tropical deciduous forests are
experiencing today's one side you
suggested that as habitats become more
fragmented it will be less efficient for
birds to move from one habitat to
another and therefore seed dispersal
will decrease this could lead to less
regeneration and more extinction as a
result in order to combat this we need
to create corridors and safe passages
that facilitate dispersal in the
northwestern gasp of India the World
Wildlife Foundation has created a
conservation landscapes as a result of
land clearing through conservation
practices the WWF has been able to
conserve these landscapes to the best of
their ability tropical deciduous forests
are a very special bond that exists on
the earth today they are home to
thousands of species you can't find
anywhere else in the world and are a
valuable asset to the biodiversity of
the planet considering the threats posed
on the tropical deciduous forests we
must do everything we can to combat the
degradation
is very unique biome
