Study Notes

Tropical Rainforests

Located primarily in India, Brazil, and Central America, with the largest concentration in the Amazon River Basin.
Camouflage is crucial for survival; the Green-Eyed Tree frog has textured skin that mimics tree bark, aiding in predation avoidance.
Mimicry allows animals to imitate venomous species, reducing predation risk; the Margin-winged stick insect adeptly resembles twigs.

Adaptations in Polar Regions

Polar regions, including the north and south poles, experience extreme cold with winter temperatures dropping as low as -37 °C.
Long periods of daylight and darkness can last an entire six months, impacting the ecosystem.
Dense fur in polar bears not only insulates but also helps with camouflage against the snowy backdrop.
Blubber in seals and whales provides insulation and buoyancy, serving as an energy reserve during food scarcity.

Plant Adaptations

Earth hosts around 300,000 plant species, each adapted to their habitats for survival based on light, water, soil, and nutrient availability.

Desert Plant Adaptations

Succulents store water in modified stems and leaves, essential for survival in arid environments.
Cacti have spines to minimize water loss, while deep roots help access underground water.
Dormancy allows seeds to remain inactive until sufficient moisture is available for growth.

Tropical Rainforest Plant Adaptations

Tall trees create competition for sunlight; ground-level plants often bloom in spring when sunlight is more accessible after autumn leaf drop.
Some ground-level plants can photosynthesize effectively in low light conditions.

Aquatic Plant Adaptations

Aquatic plants face challenges like low oxygen and light; many develop to float partially, optimizing for photosynthesis.
Modified stems and roots help absorb nutrients and oxygen directly from water.

Polar Region Plant Adaptations

Sparse vegetation includes sedges, dwarf shrubs, and mosses, typically under 12 inches tall.
Short stature and hairy parts assist in insulation, while permafrost limits deep root penetration in larger plants.

Adaptations Against Herbivory

Plants evolve thorns, spines, and chemical deterrents to protect against herbivore consumption.
Chemicals can create unpleasant tastes or, in severe cases, be toxic to deter grazing.

Biome Definition and Classification

Biomes combine climate, plants, and animals to create distinct habitats classified into terrestrial (land) and aquatic (water) categories.
Terrestrial habitats include forests, grasslands, deserts, and mountains, while aquatic includes freshwater and marine ecosystems.

Types of Plant Adaptations

Annuals/Drought Evaders: Live for a few weeks longer than rains, with small sizes and thick, waxy leaves.
Succulents/Drought Resisting: Store water in roots, stems, or leaves; includes plants like cacti and aloe.
Nonsucculents/Drought Enduring: True xerophytes that endure both external and internal dryness, e.g., Acacia.
Drought Avoiding Plants: Complete life cycles before summer, utilizing brief wet periods.

Halophytes and Mangroves

Halophytes thrive in saline environments; examples include Rhizophora and Avicennia found in marshy coastal areas.
Features of mangrove plants include stilt roots for stability and pneumatophores for gas exchange above water.
Viviparous germination in mangrove plants allows seedlings to stabilize in mud while remaining above water level.

Mesophytes

Grow under average temperature and moisture conditions, positioned between hydrophytes and xerophytes.
Develop robust root systems with well-formed tissues and structures optimized for water absorption and support.
