Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.
The hybrid zone may change depending on the fitness strength and the reproductive barriers of the hybrids.
Answer:
In a fair test two or more things are compared. In order for a test to be fair or scientifically sound, children are required to ensure only one thing (this is called a variable) is changed.
For example, if testing which material is the most waterproof by pouring liquid onto a selection of different materials, in a fair test only the type of material (the component you are testing) should be changed. Therefore all other elements (the type of liquid used, the amount of liquid used, the distance the liquid is poured from, the speed at which it is poured and the size of the material) must remain the same each time the test is carried out. It would be unfair or an unscientific test if, for example, 1000ml of water were poured onto a piece of foil and 2ml of milk poured onto a piece of foam – you would not be able to fairly compare the materials.
hope this will help you!!!.....
Natural Selection helps animals survive in their habitats and they have adaptations to help them survive better.
Answer:
Prokaryotes have the most primitive and simplest form of the cellular structure. This advantage the prokaryotes advantages over the eukaryotes in quick reproduction and easy adaptation to any new environment. ... An advantage of eukaryotic cells over prokaryotic cells include compartmentalization in the form of organelles.
