Beavers

The beaver and the capybara are the world's largest rodents. But beavers are related more closely to squirrels. Typical contributions include questions about this semi-aquatic animal's defensive behaviors, geographic ranges, keystone roles in pond building and wetland health, survival threats, and troubled interactions with people.

Why does the root need root hairs for the uptake of water and minerals?

Root hairs increase the surface area of the root for greater absorption of water and minerals. This allows the root to access a larger volume of soil for nutrients and water uptake, contributing to the plant's overall growth and nutrition.

What basic need do beavers satisfy when they build their dams?

Beavers build dams to create a safe habitat by flooding an area to protect themselves from predators, regulate water levels, and store food for the winter. By building dams, beavers can access food more easily and create a sheltered environment for their family.

Do river otters kill beavers?

This information is according to information from Wikipedia

Mammals are rarely consumed by river otters and are not a major dietary staple.Mammals that are preyed upon by otters are characteristically small or are a type species found in riparian zones.[The few occurrences of mammals found in the river otter's diet include: Muskrats (Ondatra zibethicus); Meadow Voles (Microtus pennsylvanicus); Eastern Cottontails (Sylvilagus floridanus); and Snowshoe Hares (Lepus americanus).

There are varying records of otters preying upon beavers (Castor canadensis). Otter predation on beavers has been reported in the southern boreal forest of Manitoba.Trappers in Alberta, Canada commonly assert that otters are major predators of beavers.A 1994 river otter study reported findings of beaver remains in 27 out of 1,191 scats analyzed.However, many other studies did not report any findings of beaver remains in the scat sampled.

(Scat is animal droppings)

Other web sites also say that river otters will sometimes kill muskrats or beavers to take over their dens/lodges. Survival of the fittest.

Many zooflagellates live in lakes and streams where they?

Many zooflagellates live in lakes and streams where they play important roles in the ecosystem as primary consumers, feeding on bacteria and algae. They are a key component of the food web, transferring energy to higher trophic levels through predation by other organisms. Some zooflagellates are also parasitic, infecting a variety of hosts in aquatic environments.

What symmetry does a beaver have?

Beavers, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

What animal has over 300 bones in its backbone?

A snake has more than 300 vertebrae in its backbone, allowing for exceptional flexibility and agility in movement.

Do beavers build their dams at night?

We have Beavers on our property. After repeatedly tearing the dams down, within the next few days they will be rebuilt. I walk the property each day and have noticed that the only construction done is always done at night. I can't say that in an environment where there are not any people that they only build at that time. Around our house in the North Ga Mountains our Beavers do.

If a beaver builds a dam is that primary or secondary succession?

The beaver building a dam would be considered a form of secondary succession because the beaver is altering an existing ecosystem rather than colonizing a new, barren area. The dam creates new habitat and changes the environment, allowing for new species to establish and thrive.

What animals live in the same ecosystem as a beaver?

Animals that live in the same ecosystem as a beaver include otters, muskrats, ducks, geese, frogs, fish, and various bird species. These animals often rely on similar aquatic habitats and resources provided by the beaver's activities such as dams and lodges.

Do beavers have bilateral symmetry?

Yes. Beavers, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

The temperature regulating center of vertebrate in animals is located in the?

The temperature regulating center in vertebrate animals is located in the hypothalamus of the brain. This area helps to maintain homeostasis by detecting changes in body temperature and initiating appropriate responses to regulate it. The hypothalamus can signal for processes like sweating, shivering, or changes in blood flow to help control body temperature.

Where do animals with back bones live?

Animals with backbones, or vertebrates, can be found in various habitats around the world, including forests, grasslands, deserts, mountains, rivers, lakes, and oceans. They have adapted to thrive in different environments based on their physical characteristics and behaviors.

Why did Eddie brigatti leave the rascals?

Eddie Brigatti left The Rascals in 1970 due to creative differences and a desire to pursue a solo career. He wanted to explore different musical styles and felt that his time with the band had come to an end.

What animals have a back bone?

Around 3% of animals are vertebrates (animals that have a backbone). This includes approximately 64,000 species.

Examples of animals that have a backbone are; sharks, reptiles, mammals and birds.

Will a beaver pond become a meadow overtime?

Over time, a beaver pond may transition into a meadow if the beavers abandon the area or if the dam is breached, allowing the water to drain. As the water recedes, sediment accumulates, providing a substrate for vegetation to grow. This can lead to the formation of a meadow as the ecosystem evolves.

If He has a total of 11 snakes and elephants in stock The animals that he has in stock have a total of 12 legs How many of his animals are snakes?

Let's denote the number of snakes as "S" and the number of elephants as "E". Since there are a total of 11 animals in stock, we know that S + E = 11. Given that the total number of legs is 12, snakes have no legs and elephants have 4 legs each. Thus, 4E = 12. Solving the system of equations, we find S = 11 - E = 11 - (12/4) = 11 - 3 = 8.Therefore, there are 8 snakes in stock.

Are beavers herbivores?

Herbivore, because they eat only plants

The beaver eats tree bark and cambium, the soft tissue that grow under the bark of a tree. They especially like the bark of willow, maple, birch, aspen, cottonwood, beech, poplar, and alder trees. Beavers also eat other vegetation like roots and buds and other water plants. The beaver has a specialized digestive system that helps it digest tree bark.

Could a glacier leave behind petrified wood?

No, a glacier would not be able to leave behind petrified wood. Petrified wood forms when wood is buried underground and minerals slowly replace the organic material, a process that takes thousands to millions of years. Glaciers can transport and erode materials, but they do not create petrified wood.

Why is the beaver important?

Beavers are important for their role in ecosystem engineering. They create wetland habitats that benefit a wide variety of plant and animal species, help control flooding by building dams, and improve water quality by filtering pollutants. Their activities contribute to the overall health and biodiversity of ecosystems.

How does fungi help the environment?

Fungi help the environment by eating bad or harmful bacteria and by protecting the good or harmless bacteria.

Fungi are heterotrohic organisms with thick chitin wall. Fungi finds a place in fermentation technology, antibiotic production, production of enzymes used in genetic engineering and other processes, bioactive production etc. Apart from these beneficial uses the fungi also produces many diseases and cause both animal and plant loss.

How does a beaver move a tree to his dam?

A beaver will chew down a tree near water using its strong teeth. It then uses its powerful body to drag the tree to the dam site by swimming while pushing or pulling the tree along the water's surface. Once the tree reaches the dam, the beaver will strategically position and secure it in place using mud, rocks, and other materials to strengthen the dam structure.

What is the proper name for EDTA and what is it?

Answer

EDTA is ethylenediamine tetraacetic acid. It's a strong chelating agent. It has many uses including:

  • Industrial cleaning: complexation of Ca2+ and Mg2+ ions, binding of heavy metals.
  • Detergents: complexation of Ca2+ and Mg2+ (reduction of water hardness).
  • Photography: use of Fe(III)EDTA as oxidizing agent.
  • Pulp and paper industry: complexation of heavy metals during chlorine-free bleaching, stabilization of hydrogen peroxide.
  • Textile industry: complexation of heavy metals, bleach stabilizer.
  • Agrochemicals: Fe, Zn and Cu fertilizer, especially in calcareous soils.
  • Hydroponics: iron-EDTA is used to solubilize iron in nutrient solutions.

More specialised uses of EDTA are:

  • Food: added as preservative to prevent catalytic oxidation by metal ions or stabilizer and for iron fortification.[citation needed]
  • Approved by the FDA as a preservative in packaged foods, vitamins, and baby food.
  • Personal care: added to cosmetics to improve product stability.[citation needed]
  • Oil production: added into the borehole to inhibit mineral precipitation.[citation needed]
  • Dairy and beverage industry: cleaning milk stains from bottles.[citation needed]
  • Flue gas cleaning: removal of NOx.
  • Dentistry as a root canal irrigant to remove organic and inorganic debris (smear layer).[citation needed]
  • Soft drinks containing ascorbic acid and sodium benzoate, to mitigate formation of benzene (a carcinogen).[citation needed]
  • Recycling: recovery of lead from used lead acid batteries.

Medicine:

  • EDTA is used in chelation therapy for acute hypercalcemia, mercury poisoning and lead poisoning[4].
  • Combined with chromium, EDTA is used to evaluate kidney function. It is administered intravenously and its filtration into the urine is monitored. This method is considered the gold standard for evaluating glomerular filtration rate, Cr-EDTA's sole way out of the body is via glomerular filtration as it is not secreted or metabolised in any other way.
  • Used as anticoagulant for blood samples
  • In veterinary ophthalmology EDTA may be used as an anticollagenase to prevent the worsening of corneal ulcers in animals.
  • Some laboratory studies also suggest that EDTA chelation may prevent collection of platelets ([or plaque] which can otherwise lead to formation of blood clots and prevent blood flow) on the walls of blood vessels [such as arteries]. These ideas are theoretical, however. [3]

In laboratory science, EDTA is also used for:

  • Scavenging metal ions: in biochemistry and molecular biology, ion depletion is commonly used to inactivate metal-dependent enzymes which could damage DNA or proteins
  • Complexometric titrations.
  • Buffer solutions.
  • Determination of water hardness.
  • EDTA may be used as a masking agent to remove a metal ion which would interfere with the analysis of a second metal ion present
  • An anticoagulant in medical and laboratory equipment.
  • A preservative (usually to enhance the action of another preservative such as benzalkonium or thiomersal) in ocular preparations and eyedrops. See "les conservateurs en opthalmologie" Doctors Patrice Vo Tan & Yves lachkar, Librarie Médicale Théa.
  • A titrant used to determine nickel concentration in an electroless nickel plating bath.
  • In metallography to remove staining due to etchants. Metal oxides are removed by gently swabbing with EDTA and rinsing in water.

Can you give us some information about beavers?

Beavers like to chew things especially wood and they also need some twigs so that they can build their homes.They also need lots of mud and water to build their homes the entrance to their homes are under water and the home is over the water beavers eat fish and I think they eat scallops.Inside their home there is a tunnel and then a main room!

How do you kill beavers?

you just shoot in the head with a fricking 12 gage.

It as illegal to kill beavers in most locations that they are found. To answer the question - you should not kill beavers!

There is a new solution I came across that a company is working on it is called The Beaver Defeater. It will keep beavers from building dams in critical areas such as culverts to stop the damages of Beaver flooding. You can check out the device for yourself at http://www.thebeaverdefeater.com
