Native insects and pathogens are an important part of a healthy forest ecosystem, but when environmental and biological conditions favor their development into outbreak status they can cause significant losses to forests. Several of these insects and pathogens, such as bark beetles and root diseases, have had extensive impacts forests in western and southern forests. Forest Health Protection along with state, Federal and Tribal partners survey, monitor and manage infestations of these native pest outbreaks.

An invasive species is an alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health (Executive Order 13112). Species invasions are one of the main ecological consequences of global changes in climate and land use. Most invasions over the past several centuries have involved species transported directly or indirectly by humans. Forest Health Protection will continue to work very closely with its partners to manage native and non-native pests and reduce the flow of non-native invasive forest pests into the U.S. Forest Health Protection's vision is that the Forest Service will maintain a robust program that protects the nation's forests from extraordinary levels of damage from both native and non-native invasive insects, pathogens, and plants through the continued implementation of an integrated system of prevention, eradication, management, and restoration.

Forest Health Monitoring is a national program designed to determine the status, changes and trends in indicators of forest health on an annual basis. This program collects information from a wide variety of sources including ground surveys, aerial detection and remote sensing. Forest Health Monitoring data is utilized by researchers who use it in detailed investigations into specific issues, by managers who develop strategies to deal with forest health issues, and by the public at large in order to better understand the processes that drive these natural systems. Forest Health Monitoring provides an updated synopsis of the state of our nation's forested lands, and serves as the repository of records regarding forest condition over time.

Proteins are composed of amino acids that are required for the build of our tissues. The proteins in our regular diet help the growth, repair, and also maintenance of body tissues. The body can convert proteins to glucose to regulate blood glucose levels to meet the required energy levels.
Proteins are available in different quantities in different foods, including dairy, poultry, seafood, meat, beans, peas, nuts, seeds, products, and other dairy products.
Proteins are organic compounds that include amino acids joined by amide bonds. The body does not synthesise the essential amino acids.
Amino acids are organic compounds that consist of nitrogen, carbon, hydrogen, and oxygen atoms. Our body desires twenty different amino acids to grow and perform properly. At the same time, all twenty of those are vital for your health.
Out of 20, there are 9 essential amino acids; each of them performs a variety of vital jobs in your body. These amino acids are as follows:
I) Phenylalanine
Your body turns this aminoalkanoic acid into the neurotransmitters aminoalkanoic acid, dopamine, epinephrine, and noradrenaline. Phenylalanine plays an integral role in the performance of proteins and enzymes and also the production of alternative amino acids.
ii) Valine
Three branched-chain amino acids mean branching far from one aspect of its molecular structure. Valine is a supporting source to stimulate muscle growth and the regeneration process associated with energy production.
iii) Threonine
Threonine is the principal part of structural proteins, like scleroprotein and albuminoid. It conjointly plays a task in metabolism and immune operation.
iv) Tryptophan
Tryptophan essential amino acid could be a precursor to monoamine neurotransmitters. This neurochemical regulates your appetite, sleep, and mood.
V) Methionine
Methionine acid plays a crucial role in metabolism and detoxification. It's conjointly necessary for tissue growth and also for the absorption of metal.
VI) Leucine
Leucine is important for supermolecule synthesis and muscle repair. It conjointly helps regulate blood glucose levels, stimulates wound healing, and produces growth hormones.
VII) Isoleucine
Isoleucine essential amino acid is concerned with muscle metabolism and is heavily targeted in muscle tissue. It's conjointly vital for immune operation, Hb production, and energy regulation
VIII) Lysine
The essential amino acid plays a major role in supermolecule synthesis, metallic element absorption, and also in the production of hormones and enzymes. It's jointly vital for energy production, immune function, and also the production of scleroprotein and albuminoid.
IX) Histidine
The human body uses histidine to give neurochemicals that are very useful to immunologic responses, proper digestion, sexual activity, and maintaining sleep cycles. Histidine is also required for protecting barriers that surround your entire nerve cells.
Micronutrients
Micronutrients support the body's metabolism. Dietary minerals typically are trace parts, salts, or ions like copper and iron. Several minerals are required to regular human metabolism.
Vitamins are composed of organic compounds required for the body. They sometimes act as coenzymes or cofactors for numerous proteins within the body.
The second main chemical constituent of the plasma membrane is protein. Integral proteins are encapsulated in the plasma membrane and might stretch a part or all of the membrane and act as pumps or channels that help in the movement of particles inside and outside of the cell. Peripheral proteins are present on the internal areas or exterior of the plasma membrane, attached to either phospholipid molecules or to integral proteins. Integral and peripheral proteins both acts as enzymes, as constructural bonds for cytoskeleton fires, or as a component of recognition sites of the cell.
Receptors are the recognized sites on the membrane that are sites for attachments for materials that collaborate with the cell, and each receptor is formed to attach to a particular material. The attachment of a particular material to its receptor on the plasma membrane accelerates activities inside the cell, like stimulating enzymes engaged in metabolic pathways. These metabolic pathways are important for giving energy to the cell, preparing substances for the cell or toxins for discarding or breakdown of the cell's waste. In addition, neurotransmitters and extracellular hormones attach to receptors of the plasma membrane that transfer a signal into the cells to molecules inside the cell. Viruses use some recognition sites as attachment points. Howbeit they are largely specified, disease-causing organisms like the virus may emerge to misuse the recognition sites to enter inside the cell by imitating the particular substance that is meant to be bound with the receptor. This particularity aids in the explanation of why HIV (Human Immunodeficiency Virus) or the hepatitis virus conquers only particular cells.
These large hairy spiders are facing threats to their survival, primarily due to habitat destruction. As humans clear forests for various purposes, tarantulas lose their homes and food sources, pushing some species toward extinction.
Additionally, the exotic pet trade poses another danger. The high demand for pet tarantulas leads to their capture from the wild, resulting in declining populations. In response to the declining population, the US Fish and Wildlife Service decided to protect 11 species already considered threatened and endangered.
These species are the following: Poecilotheria formosa, Poecilotheria hanumavilasumica (endangered), Poecilotheria metallica (critically endangered and highly sought after in the global pet trade), Poecilotheria miranda, Poecilotheria rufilata, Poecilotheria striata, Poecilotheria fasciata, Poecilotheria ornate (near threatened), Poecilotheria pederseni, Poecilotheria smithi (vulnerable), and Poecilotheria subfusca (near threatened).
Conservation efforts also focus on captive breeding programs to meet the demand for pet tarantulas without harming wild populations.

Healthy forests provide ecological services like air purification, water filtering, climate modulation, and flood and erosion control. They also produce better economic yield.
September 22 is World Rhino Day, an annual commemoration of the five species that share our planet - the Black, White, Indian, Javan, and Sumatran rhinos.
This event reminds us of these creatures' challenges, including habitat loss and poaching. More importantly, it encourages collective action to save these vital members of our global ecosystem.
Not only about rhinos, but this day also catalyzes necessary conversations about biodiversity, underscoring the invaluable role each species contributes to our ecological balance.
Mothers carry their babies in utero for a 17-month gestation period, and they give birth every three to 10 years until becoming menopausal around age 40. They are exceptionally protective of their offspring, and often adolescent females are recruited to assist in caring for calves. Mothers will nurse their babies for up to two years, forming a bond so strong that if a mother dies, the mortality rate of her sons increases. Orcas are some of the affected mammals in the ocean due to pollution, and the contaminants make their way into breastmilk, increasing the mortality rate of all young to 50% within the first year.
This fun flower looks more like a carnival toy than a creation of nature. Also known as the Catherine-wheel Pincushion, this is the most exquisite of the “firework pincushion” flowers. Not many flowers can compare to a bed of blooming Protea Pinwheels. The coolest fact about this flower is that it’s interconnected with fire. In the wild, Protea Pinwheels are perfectly suited to adapt to harsh climates. The best time for Protea Pinwheels to bloom is after a fire, when the adult plants, rodents, and other insects that would impede their growth have been destroyed. Protea Pinwheels ensure their continued existence by producing little fruit that is collected and eaten by ants. The ants do not eat the seeds, which remain dormant underground until there is a fire at which time the seeds are cued to begin germination.
Since winter comes early to Kanazawa, the yukitsuri is put up
in November. It starts with the famous Karasaki Pine in
Kenrokuen Garden.
The trees that are suppported are pines, azaleas, and fruit
trees. First a pole is propped up near the trunk of a tree and
rope is hung from it and attached to the ground, forming a
teepee-like shape. This process is especially important for
evergreen trees because they are so delicate.
There are three types of yukitsuri.
Ringo-tsuri: five ropes attached to one pole are
placed close to the trunk of a tree, and
a special decorative rope is attached to
the top of the pole.
Miki-tsuri: used to support young trees such
as pine and cherry. The rope is attached
directly to the top of a tree and hangs
directly into the lower branches of the
tree giving it proper support.
Shibori: used on shrubs such as bush clovers
and azaleas. Rope is used to gather all
the branches into a bottle-like shape.
This method is used to protect the plants
from snow piling up on the ground around
them.
The most popular method is Ringo-tsuri, and all the famous and
older trees in Kenrokuen Garden are supported in this manner.
Female hippos are called cows. They give birth to babies every 2 years. They usually give birth to one young at a time. Then they enter their group under the leadership of a strong man. They do this to escape from more ferocious animals including lions, hyenas, crocodiles.
স্ত্রী প্রজাতির জলহস্তীদের গাভী বলা হয়। এরা ২ বছর পর পর বাচ্চা জন্ম দিয়ে থাকে। এরা সাধারনত একবারে একটি বাচ্চা জন্ম দিয়ে থাকে। এরপর এরা কোন শক্তিশালী পুরুষের নেতৃত্বে তাদের গ্রুপে ঢুকে পড়ে। সিংহ, হায়েনা, কুমির সহ আরও হিংস্র প্রানীর হাত থেকে রক্ষা পাওয়ার জন্য এরা এমন করে থাকে।
