Darwin’s Finches
Ask the kids to read about and conduct research on the Galapagos finches Darwin observed. Darwin observed that the beaks of various finches varied. He also observed that each variety of beaks was best suited for handling a particular kind of food. Darwin was aware that the finches came originating from South America's continent, but the ones he observed on the islands were distinct from those he had previously seen there. Darwin questioned why these finches changed once they reached the Galapagos Islands. Test the capacity of various beaks to obtain various foods with your kids. Give kids toothpicks, little bird seeds, huge bird seeds (sunflower seeds), foam packing peanuts, metal binder clips, tweezers, and spoons to depict various beak varieties. Have the student experiment with the various instruments to see which one goes best with which foods.

Predict which mechanism of reproductive isolation played a role in trumpeter speciation in the Amazon basin. Note: Trumpeters cannot fly across large rivers.
Habitat isolation is likely to be most relevant in the case of trumpeters in the Amazon basin.
If trumpeters can not cross rivers, then they would be able to mate with trumpeters on the same side of the river but not on the other side- a form of prezygotic isolation.
what are trumpeters?
The term "trumpeter" comes from the deep, booming territorial call of these chicken-sized, long-necked, hunch-backed, small-headed, short-tailed, dark-plumed, long-legged birds that wander the jungle floors of South America.The land of South America that now the Amazon River and its tributaries drain is recognized as the Amazon basin.

---------------- is the finest material can be blasted more than 20 kilometers into the atmosphere and carried much farther downwind than the larger blocks which fall to earth on the volcano itself.
Pyroclastic materials are classified according to their size, measured in milli meters: dust (less than 0.6 mm [0.02 inch]), ash (fragments between 0.6 and 2 mm [0.02 to 0.08 inch]), cinders (fragments between 2 and 64 mm [0.08 and 2.5 inches], also known as lapilli), blocks (angular fragments greater than 64 mm), and bombs (rounded fragments greater than 64 mm).
The fluid nature of a pyroclastic flow is maintained by the turbulence of its internal gases. Both the incandescent pyroclastic particles and the rolling clouds of dust that rise above them actively liberate more gas. The expansion of these gases accounts for the nearly frictionless character of the flow as well as its great mobility and destructive power.
Pyroclastic flow, in a volcanic eruption, a fluidized mixture of hot rock fragments, hot gases, and entrapped air that moves at high speed in thick, gray-to-black, turbulent clouds that hug the ground. The temperature of the volcanic gases can reach about 600 to 700 °C (1,100 to 1,300 °F). The velocity of a flow often exceeds 100 km (60 miles) per hour and may attain speeds as great as 160 km (100 miles) per hour.

The property rights approach to environmental issues often becomes highly relevant in cases involving endangered species.
The approach based on property rights postulates that if exclusive property rights are correctly established, the public good of maintaining high environmental quality may be converted into a private good, and the best possible distribution of environmental resources will be accomplished.
The protection of people's property rights is an efficient method for preserving and rehabilitating endangered animals. It is more likely that recovery will occur if these animals are owned by someone who will benefit in some way from their growth. But if endangered species are nothing more than a burden, any kind of financial incentive to preserve them is met with fierce opposition.

In the chesapeake bay and other bodies of water, what is a result of phytoplankton population increases?
Dead zones are created by hypoxia and the bacterial decay of dead phytoplankton.
What are the effects of excess phytoplankton population?The Chesapeake Bay, like many other bodies of water, is overrun with nutrients, which results in a type of pollution called eutrophication. Every spring, sewage treatment facilities, farms, and lawns release large amounts of nitrogen and phosphorus into the Bay. These nutrients fuel the growth of algae as the water warms up in the summer, resulting in blooms that deplete the water's oxygen content and create sizable "dead zones" where fish, crabs, and other aquatic life find it challenging to survive. During these times, some of the mud's surface layers and portions closer to the bottom may become anoxic, meaning there is no oxygen present at all.

Strengthening some synapses and weakening others establishes neural circuits that contain memories; the low-frequency stimulation of synaptic inputs to a cell can decrease their strength in a phenomenon known as long-term depression.
The effect of long-term depression can arise from neural effect of synapses. The synaptic impulses start to decrease gradually when a person is suffering from long-term depression. This decreased neural synapses arise from long-term exposure to stress that is chronic. It can also stem from anxiety. The continuous exposure of the neurons to stress and anxiety can also lead to degeneration and depletion of the cells present in the nervous system. Also the cortisol levels rise during depression and it is regulated by the hippocampus. This leads to a delay or restriction in the developing neurons inside the brain.
