The taiga, also known as the boreal forest, is a large belt of coniferous forests located in cold northern latitudes. It covers 11% of the Earth's surface, including most of Canada, Alaska, Scandinavia, and Russia. The taiga has a subarctic climate with long, cold winters and short, cool summers. It is dominated by coniferous trees like spruce, fir, and pine that are adapted to the cold climate. The taiga supports a diverse range of wildlife including birds, herbivores like moose and caribou, and predators such as wolves. However, threats from logging and hunting have negatively impacted some animal populations.
A distinct ecological community of plants and animals, living together in a particular climate, is called as a "biome." There are 9 kinds of Biomes are present in the world. This module explains the Tundra(Arctic and Alpine) Biome.

Solution
Land Biomes
These are the 8 different land biomes in order from coldest to warmest
Tundra
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning
treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little
precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a
nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by
biological fixation, and phosphorus is created by precipitation. It is also the driest biome next to
the desert.
Characteristics of tundra include:
Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations
Coniferous Forest (also known as Taiga)
The Coniferous Forest is a forest of Conifers (too much to handle, isn\'t it?). A Conifer is a tree
that produces its seeds in cones. The Pine tree is the most common example. Conifer leaves
conserve water with the thick, waxy layer that covers their leaves, also known as needles. The
vegitation in the Coniferous forest is small in size, but large enough to feed the vast herbivore
population. Most of these animals survive the brutal winters by migrating or hibernating.
Average Annual Rainfall- 14-29.5 in.
Average Temperatures in the Summer- 57.2°F
Average Temperatures in the Winter- 14°F
Deciduous Forest (also known as temperate forest)
Deciduous forests can be found in the eastern half of North America, and the middle of Europe.
There are many deciduous forests in Asia. Some of the major areas that they are in are southwest
Russia, Japan, and eastern China. South America has two big areas of deciduous forests in
southern Chile and Middle East coast of Paraguay. There are deciduous forests located in New
Zealand, and southeastern Australia also.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. The taiga can be found in areas in the
Northern Hemisphere
4. Largest vegetation on earth
Taiga is the Russian word for forest
Belt of coniferous forest
Located in high latitudes of the northern
hemisphere
Sunlight hits the surface of the earth and scatters
Results to large temperature differences as seasons
progresses
Covers 11% of the earth’s terrestrial surface
5. What is Ecotone?
An ecotone is a transition area between two
biomes but different patches of the landscape,
such as forest and grassland
6. 4 major vegetation zones
Forest tundra ecotone
Open stands of spruce lichens and moss
Open boreal woodland
Lichens and black spruce
Main boreal forest
Continuous strand of spruce
Pines
Boreal mixed forest ecotone
Boreal forest grades into mixed forest
12. Summer
Strong
seasonal variation
Summers are short, cool and moist
(24-hr average temp is 10 °C or more) lasts 1–3
months and always less than 4 months.
Temperature range in the summer gets as low as -7°
C (20° F).
The high in summer can be 21° C (70° F). The
summers are mostly warm, rainy and humid.
Influenced by northern hemisphere location
13.
14. Winter
Winters are prolonged, harsh and dry w/ long lasting
snowfall
The winter temperature range is -54 to -1° C (-65
to 30° F).
15.
16. Precipitation
The total precipitation in a year is 30 - 85 cm
(12 - 33 in)
The forms the precipitation comes in are
rain, snow and dew.
Most of the precipitation in the taiga falls as
rain in the summer.
17. Permafrost
Perenially
frozen subsurface that may be
hundreds of meters deep
Upper layer thaw in summer
Refreezes in winter
Develops when ground temp is below O˚C
18.
19.
20. Impervious to water
Waterremains and moves above it
Ground thus stays soggy even though precipitation is
low
This enables plants to exist
Accumulated organic matter protect the
permafrost
Shading and insulation
Reduces warming and retard thawing of the soil in
summer
23. The type of soil is called Pozol
are the typical soils of coniferous, or boreal
forests
sandy and excessively drained
poor soils for agriculture
Taiga soil tends to be young and poor in
nutrients.
It lacks the deep, organically enriched profile
present in temperate deciduous forests.
24. Since the soil is acidic due to the falling pine
needles, the forest floor has only lichens and
some mosses growing on it.
25.
26. Effect of permafrost to soil
Vegetationand organic debris impede the thawing of
the permafrost and act to conserve it
Permafrost chills the soil
Retarding the growth of both above ground and below
ground parts of plants
Limits activity of soil microorganisms
Diminishes aeration and nutrient content of soil
The colder the soil becomes, the closer to the surface
the permafrost moves, and the more shallow the soil
becomes
27. The effect becomes more pronounced the closer the
permafrost is to the surface of the soil
This contributes to the formation of shallow root
systems by plants
This is in order to get more water from the surface
28. Lichens retain soil moisture through the
growing season, encouraging the growth of
trees on sites that would otherwise be too dry.
30. Decomposition
Because of cool temperatures decomposition
is slow in the taiga.
Undecayed vegetation builds up on the forest
floor, making it feel like a sponge.
Since decomposition is slow, the soil is thin
and lacking in nutrients.
Trees grow taller where warmer temperatures
allow for faster decomposition or by streams
and rivers which carry nutrients from higher
ground.
32. Fires are reoccurring events in the taiga
During periods of drought, fires can sweep
over hundreds of thousands of hectares.
All boreal species, both broadleaf trees and
conifers are well adapted to fire
Unless too severe, fire provides a seedbed for
regeneration of trees
33.
34.
35. The Taiga appears as an endless sweep of
sameness – a blanket of spire-shaped
evergreens over the landscape.
The boreal forest conifers fall into 3 growth
forms (1) the spire-shaped spruces and fir.
(2) The open, thin, light-penetrating upper
canopy of pines and (3) the deciduous larch.
36. Only a thick carpet of mosses
grows in the dense shade of
spruce, while lichens grow
under pine.
37. Conifers are well suited to
the cold taiga environment.
The narrow, needlelike leaves
with their thickened cuticles
and sunken stomata reduce
transpiration and assist in
moisture conservation during
periods of summer drought
and winter freeze.
38. The dark green color of spruce
and fir needles helps the
foliage absorb maximum heat
from the sun and begin
photosynthesis as early as
possible.
Conical shape - promotes shedding of
snow and prevents loss of branches.
Evergreen habit - retention of foliage
allows plants to photosynthesize as soon
as temperatures permit in spring, rather
than having to waste time in the short
growing season merely growing leaves.
39. Black spruce (ability to tolerate
wet soils and occupies
cold, north-facing slopes and
bottomlands)
White Spruce and Birch
grow on permafrost-free
south-facing slopes.
40. For some species, wildfires (with return
times of between 20–200 years) are a
necessary part of the life cycle in the
taiga; some, e.g. Jack Pine have cones
which only open to release their seed
after a fire, dispersing their seeds onto
the newly cleared ground.
42. Insects play a critical role
as pollinators, decomposers, and as a part of
the food web.
Many nesting birds rely on them for food.
BIRDS
More than 300 species of birds have
their nesting grounds in the taiga. Siberian
Thrush, White-throated Sparrow, and Black-
throated Green Warbler migrate to
this habitat to take advantage of the long
summer days and abundance of insects found
around the numerous bogs and lakes.
43. Siberian Thrush
Black-throated Green Warbler
White-throated sparrow
44. Birds also feed and extract conifer
seeds from cones, thus helping in
the dispersal of seeds of trees.
45. The Taiga is home to a number of
large Herbivorous mammals, such
as moose and reindeer/caribou. Some areas of the more
southern closed boreal forest also have populations of other
deer species such as the elk (wapiti) and roe deer.
