Economic zoology deals with minimizing the harmful effects of animals and maximizing their beneficial effects. Animals provide important economic benefits like food, fiber, labor, and byproducts. Cattle, pigs, sheep, goats, horses and donkeys are economically useful livestock. Pearls, gelatin, and musk are valuable animal byproducts. However, some animals can also cause economic harm through diseases like foot and mouth, Chagas disease, anthrax, and rabies. These diseases infect livestock and humans, causing symptoms like fever, blisters, irregular heartbeat, and neurological issues. Effective control and prevention of diseases is important in economic zoology.
This document will help you and will clear your concepts about the terms of Orthogenesis, Allometry & Adaptive Radiations, which are usually studied in evolution.
When a perfectly harmless animal resembles in its colour and shape, with a well protected species, the phenomenon is called mimicry.
The concept of mimicry was first given by H. W. Bates in 1862.
Mimicry is an important feature of organism which protect the animals against enemies. Mimicry often used as self defense which increases the survival value of organisms.

Taxonomy: Taxonomy is the science of defining and naming groups of biological organisms on the basis of shared characteristics.
The classification of organisms is according to hierarchal system or in taxonomic ranks (eg; domain, kingdom, phylum class, order, family, genus and species) based on phylogenetic relationship established by genetic analysis.
Taxonomic Collection : Biological collection are typically preserved plant or animals specimens along with specimen documentations such as labels and notations.
Dry Collection - Dry collections consist of those specimens that are preserved in a dry state.
Wet Collection - Wet collections are specimens kept in a liquid preservative to prevent their deterioration.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
1. Basic Concepts In Economic Zoology
Economically Harmful and Useful Animals
2. Economic Zoology
Combination of two words = Eonomic+Zoology
Economics:
“Study of resources and expenditures of a country.”
Zoology:
“Study of structure, physiology, development and classification of
animals.”
Economic Zoology:
“Deals to minimize harmful effects of animals and to enhance their
useful effects in the society to improve our living by getting
benefits from them.”
Significance of Economic Zoology:
• Animals are good source of food (meat,milk,egg,sea food)
• Animals are useful for livestock and domestic purposes e.g cattle,
sheep, pigs, goats, horses, donkeys, and mules; other animals, such
as buffalo and camels for agricultural purposes.
3. Economically Useful Animals:
1. Cattle
• Make up the largest livestock group worldwide. Among those
prominent in beef and milk production .
• Cattle are sometimes used as draft animals, particularly in
small-scale farming and in less developed regions.
• The most widely consumed meat is beef, the flesh of
mature cattle that normally weigh from 450 to 540 kg
and yield between 55 and 60 percent of their weight in meat.
2. Pigs
• Have been raised for their meat (pork) since ancient times.
• For other marketing purposes as lard, bacon, or pork.
• The pig is the world’s second largest provider of meat. When
taken to slaughter, pigs generally weigh between 90 and 135
kg and provide about 70 to 74 percent of weight in meat.
4. 3. Sheep
• Were among the first animals to be domesticated.
• Sheep are raised for the fleece or wool, meat (mutton and
lamb) and to a lesser degree for milk.
• Meat from lambs and sheep is produced on a much smaller
scale than either beef or pork.
4. Goats
• Are raised for their milk , meat, and to make leather and wool.
5. Horses
• First intensively domesticated in Central Asia, are bred not only
as livestock but also for riding, show, and racing.
6. Donkeys
• Donkeys and mules , the hybrids formed by crossbreeding a
male donkey and a female horse, are used as work animals for
farming, transportation and to obtain by-products.
5. Other By-Products
1. Pearls:
• Pearls are made by living creatures called
mollusks mainly marine oysters and freshwater
mussels.
• Mollusks commonly have a soft, un-segmented
body and a hard exterior shell, such snail
• These animals live in marine and freshwater
habitats as well as on land.
• Pearls are used for ornamental purposes mainly
jewelry.
6. 2. Gelatin:
• An insulating layer of fat under the skin of
whales and other large marine mammals or
other terrestrial animals such as pig, bear etc
are used as a source of oil.
• Gelatin is a collagen protein, a translucent,
colorless, flavorless food ingredient,
commonly derived from animal body parts by
boiling skin, tendons, ligaments, and/or bones
with water. It is usually obtained from cows or
pigs.
• Used in cosmetics, baking, paints etc
7. 3. Musk:
• It was a name originally given to a substance
with a strong odor obtained from a gland of
the male musk deer.
• The substance has been used as a popular
perfume fixative since ancient times and is
one of the most expensive animal products in
the world.
• They include glandular secretions from
animals such as the musk deer.
4. As decomposers of debris and recycling of
essential substances to the environment.
8. Economically Harmful Animals:
Some common diseases caused by animals.
• Snakes.
• Dogs (rabies) (Kills 59,000 per year)
• Assassin Bugs (Chagas disease) (Kills 10,000 per year)
• Scorpions. (Kills 3,300 humans per year)
• Crocodiles. (Kills 1,000 humans per year)
• Elephants. (Kills 600 humans per year)
• Hippos. (Kills 500 humans a year)
• Lions. (Kills 200 humans per year)
• Ascaris roundworms (2,500)
• Tapeworms (2,000)
9. Economically Harmful Animals:
1. Foot and mouth disease (FMD): (Viral disease)
• It is a severe, highly contagious viral disease of
livestock that has a significant economic impact.
• The disease affects cattle, swine, sheep, goats
and other cloven-hoofed ruminants.
• Affected animals have a high temperature, which
is followed by the development of blisters chiefly
in the mouth and on the feet.
10. Signs of Foot and Mouth in Cattle
• slobbering and smacking lips
• shivering
• tender and sore feet
• reduced milk yield
• sores and blisters on feet
• raised temperature
11. 2. Chagas disease: (Parsitic disease)
• Chagas disease is an inflammatory, infectious disease
caused by the parasite Trypanosoma cruzi.
• This parasite is found in the feces of the triatomine
bug. This bug is also known as the "kissing bug.“
• These insects can become infected by this parasite
when they swallow blood from an animal that is
infected with the parasite.
Transformation to Humans:
• The parasites can then enter your body through your
eyes, mouth, a cut or scratch, or the wound from the
bug's bite.
12. • Eating uncooked food contaminated with feces
from bugs infected with the parasite.
• Getting a blood transfusion or an organ
transplant from someone who was infected with
the parasite.
• Being accidentally exposed to the parasite while
working in a lab.
• Spending time in a forest that contains infected
wild animals, such as raccoons and opossums.
13. Acute phase
• The acute phase of Chagas disease, which lasts for weeks or
months, is often symptom-free. When signs and symptoms do
occur, they are usually mild and may include:
• Swelling at the infection site
• Fever
• Fatigue
• Rash
• Body aches
• Eyelid swelling
• Headache
• Loss of appetite
• Nausea, diarrhea or vomiting
• Swollen glands
• Enlargement of your liver or spleen
14. In some cases, if the infection isn't treated, Chagas disease will
advance to the chronic phase.
Chronic phase
• Signs and symptoms of the chronic phase of Chagas disease
may occur 10 to 20 years after initial infection, or they may
never occur. In severe cases, Chagas disease signs and
symptoms may include:
• Irregular heartbeat
• Heart failure
• Sudden cardiac arrest
• Difficulty swallowing due to enlarged esophagus
• Stomach pain or constipation due to enlarged colon
15. 3. Anthrax: (Bacterial disease)
• Anthrax Anthrax, a highly infectious and fatal disease of
cattle, is caused by a relatively large spore- forming
rectangular shaped bacterium called Bacillus anthracis
Symptoms:
• Very occasionally some animals may show trembling, a
high temperature
• Difficulty breathing, collapse and convulsions before
death.
• After death blood, may not clot, resulting in a small
amount of bloody discharge from the nose, mouth and
other openings
16. 4. Rabies (Viral Disease):
• Rabies is a dangerous virus that causes brain
inflammation in humans and other mammals. Animals
carrying the infection can spread rabies to human
through bites and scratches.
• Rabies virus gets into your body when the saliva (spit)
of an infected animal gets into an open wound (usually
from a bite).
• It moves very slowly along nerves into your central
nervous system (your brain and spinal cord). When it
reaches your brain, the damage causes neurological
symptoms. From there, rabies leads to coma and
death.
17. Symptoms of rabies
• Fever.
• Tiredness (fatigue).
• Bite wound burning, itching, tingling, pain or numbness.
• Cough.
• Sore throat.
• Muscle pain.
• Nausea and vomiting.
• Diarrhea.
Neurological symptoms of rabies
• Neurological symptoms of rabies are either furious or
paralytic. Furious rabies symptoms may come and go with
periods of calmness in between.
