Special mention of a few native New Zealand Frogs is made.
Why do animals need to breathe?
Breathing is important to organisms because cells require energy (oxygen) to move, reproduce and function. Breath also expels carbon dioxide, which is a by-product of cellular processes within the bodies of animals.
Respiration is the process of releasing energy from food and this takes place inside the cells of the body.
The process of respiration involves taking in oxygen (of air) into cells, using it for releasing energy by burning food, and then eliminating the waste products (carbon dioxide and water) from the body.
Respiration is essential for life because it provides energy for carrying out all the life processes which are necessary to keep the organisms alive.
The energy produced during respiration is stored in the form of ATP (Adenosine Tri- Phosphate) molecules in the cells of the body and used by the organism as when required.
KEY POINTS
Life started in an anaerobic environment in the so called ‘primodial broth’ (a mixture of organic molecules.
Subsequently, oxygen strangely enough became an crucial factor for aerobic metabolism especially in the higher life forms.
The rise of an oxygenic environment was an important event in the diversification of life.
It evoked a dramatic shift from inefficient to sophisticated oxygen dependent oxidizing ecosystems.
Anaerobic fermentation, the metabolic process that prevailed for the first about 2 billion years of the evolution of life, was a very inefficient way of extracting energy from organic molecules. Ex: A molecule of glucose, e.g., produces only two molecules of ATP (≈ 15 kCal) compared with 36 ATP molecules (≈ 263 kCal) in oxygenic respiration.
Aerobic metabolism must have developed at a critical point when the partial pressure of oxygen rose from an initial level to one adequately high to drive it passively across the cell membrane.
Respiration is a complex and highly integrated biomechanical, physiological, and behavioral processes.
The transfer of O2 occurs through a flow of tissue barriers and compartments by diffusion down a partial pressure gradient, which drops to about zero at the mitochondrial level.
Acquisition of molecular oxygen (O2) from the external fluid media (water and air) and the discharge of carbon dioxide (CO2) into the same milieu is the primary role of respiration.
The respiratory system is a biological system consisting of specific organs and structures.

There are main 5 classes of living echinoderms:
crinoids (sea lilies and feather stars); asteroids (STARFISH); ophiuroids (brittle stars); echinoids (SEA URCHINS, etc); and holothuroids (sea cucumbers).
Echinoderms have been well preserved as FOSSILS; all existing classes and several others now extinct were present in the Ordovician (505-438 million years ago). They may have originated in the Precambrian (over 570 million years ago).
Common name : sea lilies, Sea Stars(STARFISH), sea urchins, sea cucumbers, and brittle stars.
Habitat
Echinoderms occupy all habitats including coral reefs, mangroves, seagrass and soft-bottom areas.
Except for a few species which inhabit brackish waters, all echinoderms are benthic organisms found in marine environments. Echinoderms inhabit depths ranging from shallow waters at tide lines to the deep sea.(Barnes, 1987; Brusca and Brusca, 2003; University of Alabama Center for Communication and Educational Technology, 2000; Waggoner, 1999)
Habitat Regions
• temperate
• tropical
• polar
• saltwater or marine
Aquatic Biomes
• brackish water
Other Habitat Features
• intertidal or littoral
GeoGraphy and eco-system
Geographic Range
Mainly a marine group, echinoderms are found in all the oceans. (Brusca and Brusca, 2003)
BIOGEOGRAPHIC REGIONS
• arctic ocean
• indian ocean
• atlantic ocean
• pacific ocean
• mediterranean sea
Eco-system
Sea urchins are among the main herbivores on reefs and there is usually a fine balance between the urchins and the kelp and other algae on which they graze. A diminution of the numbers of predators (otters, lobsters and fish) can result in an increase in urchin numbers causing overgrazing of kelp forests with the result that an alga-denuded "urchin barren" forms.

Ecosystem Roles
Echinoderms are usually intricate parts of their ecosystems. Many asteroids are keystone species. Sea urchins, if not controlled by predators, may overgraze their habitat. Asteroids have several commensals, including polychaetes that feed on leftovers from the sea star's prey items. (Barnes, 1987; Brusca and Brusca, 2003)

Olé Pedersen, Patricia De Luca and Heather LeFevre presented this content at Cannes on June 21, 2011. The workshop was one of 20, selected from hundreds of entries as part of the festival conference. Participants learned the philosophy behind and practiced making cultural movements.
Organisms have different methods of reproduction. To tell the truth, these different reproductive methods are the factors that divide animals into two categories: viviparous and oviparous animals. But more on that in a bit, here's a blog on the many different animals that lay eggs!
Do you want to know about animals that lay eggs?
Nature's way of maintaining the ecological balance on earth is something special. For example, Mother Nature has endowed living animals with the ability to go through the process of labor to directly give birth to their own kind.
Whereas, oviparous animals lay eggs that give birth to young as soon as they hatch.
Now, if you are stuck wondering because nature has allocated different reproductive processes to different animals, then we are just as clueless as you!
However, you can acknowledge the fact that every process created by nature is purposeful. For example, if nature has given birds the ability to lay eggs to produce their offspring, it may be for their own benefit.
The main reason for this is that birds cannot fly while carrying the weight of their young. By laying their eggs in a remote location, they thereby safeguard both themselves and their offspring.
We also understand how interested you are in learning about the ovoid animal species.
So, read on to know more about the complex egg-laying process and a description of the top 13 animals that lay eggs.
Animals That Lay Eggs
If we were to list all oviparous animals, you would get tired of reading the never-ending list!
A large number of prominent species in the animal kingdom are oviparous, including insects, birds, amphibians, reptiles, fish and even some mammals.
So, if you are ready to know about 13 animals that lay eggs, connect with us!
Birds
Birds are the first members of our list of animals that lay eggs. Birds are the most lively and colorful species of the animal kingdom, somewhat related to the ancient family of reptiles, the dinosaurs.
They are a very unique creation of nature because they are the only animals with feathers that are known to exist on Earth. These warm-blooded vertebrates are also known to be closest to reptiles due to the rough shape of their feet.
The largest birds alive today are the North African ostriches, which can reach 9 feet in height and weigh up to 350 pounds. The ostrich egg is the largest of any other bird species.
On the other hand, the smallest extant birds are Cuban native hummingbirds weighing less than 3 grams.
Also, the bird's feathers make them stand out among every other species.
However, having wings does not guarantee a bird's ability to fly. There are several flightless birds, including penguins, kiwis and ostriches, which, although they have wings, cannot fly due to some evolution that took place over the years.
Also, bird eggs have a hard shell that ensures safety and are laid in secluded areas like bird nests, such as a treetop or an abandoned room. The parents fulfill the responsibility of taking care it...

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

2. Frogs are Amphibians…
Frogs belong to a group of animals called amphibians. (am-fib-ee-anz).
Amphibian means two-lives. Frogs begin their lives in the water as eggs and
then tadpoles and when they are fully developed they live on land. Scientists
believe that there are more than 4,000 different kinds of amphibians on Earth.
Toads, newts, salamanders and caecilians (blind worms) are also members of
the amphibian group.
3. Frogs are cold-blooded…
Frogs are cold-blooded which means that their bodies are the
same temperature as the air or water around them. When they
are cold they will lay in the sun to warm up and when they get too
warm they will go into the water to cool their bodies off.
4. Where do
frogs live?
Frogs are found all over the
world, and in every climate,
except Antarctica. They can be
found near any, and every, body
of fresh water but prefer ponds,
lakes, and marshes, because the
water doesn’t move very
fast. Frogs cannot live in the sea
or any salt water.
Scientists have found frogs
fossils that date back to the
Jurassic period over 140 million
years ago.
6. Jelly covered
Eggs…
Frogs begin their lives as
tadpoles that are hatched in
the water from tiny jelly-
covered eggs. The mother
frog can lay thousands of
eggs at one time. Imagine
having thousands of brothers
and sisters!
Tadpoles don't have eggs but frogs
have eggs that turn into tadpoles then
The jelly has an awful taste, frogs.
which protects the eggs from Frog eggs look look little jelly like
predators until they are ready sacks with little black dots in the
to hatch. middle.
7. Tadpoles…
Tadpoles are born with gills, just like a fish, so that they can breathe
under water. They have a big head and a long tail. They definitely do
not look like frogs, yet! Tadpoles have a tough life. It’s a good thing
they are fast swimmers to escape the many other creatures that hunt
them in the ponds and lakes. They are a favorite food to fish and
water beetles.
8. Metamorphosi
s
Metamorphosis is the change
of shape during an animal’s
life. During metamorphosis
the tadpole will develop back
legs first, then front legs.
Around 6 weeks of life the
mouth starts to widen.
Sometime around 10 weeks
the froglet’s, as it is now
called, eyes start to bulge out
and the tail begins to shrink
and eventually disappear.
When the lungs finish
developing the froglet makes
it’s way onto the land and, Ta-
da! It’s a frog!
9. Tadpole with legs to
Froglet…
After four weeks, the tadpole The tadpole's gills disappear and
grows two hind, or back, legs. its lungs grow stronger.
The tadpole's gills move inside its Two front legs grow where the
body. gills were.
10. What do
they eat?
Frogs are carnivores, which
means that they will eat meat.
Small to medium sized frogs
eat insects such as flies,
mosquitoes, moths and
dragonflies. Larger frogs will
eat larger insects like
grasshoppers and worms.
Some large frogs will even eat
small snakes, mice, baby
turtles, and even other
smaller frogs!
11. What about that tongue..?
Frog’s tongues are attached to the front of their mouths rather than at the
back like humans. When a frog catches an insect it throws its sticky tongue
out of it’s mouth and wraps it around its prey. The frog’s tongue then snaps
back and throws the food down its throat.
12. Characteristic
s
Frogs have very good
eyesight. They bulge out the
sides of their heads in order
for the frog to see in nearly all
directions.
Frogs also have an amazing
sense of hearing. You can
often tell the difference
between a male and female
frog by the size of their
eardrum, which can be seen
behind their eyes. If the
eardrum is smaller than the
eye, the frog is a female. On
males their eardrum is the
same size as the eye.
13. Characteristic
s
Frogs have very powerful
back legs and webbed feet
that help them jump great
distances, as well as, swim.
Frogs even use their legs to
dig, or burrow, underground
for hibernating (although not
all frogs hibernate!)
Every different species of frog
has his or her own look. They
come in many colors, patterns
and sizes.
17. Predators
…
Frogs have many predators.
Animal predators include
birds, fish and reptiles.
Some frogs are very good at
camouflaging themselves so
that they blend in with their
environment, making it harder
for their enemies to find
them. Some frogs can
change the colour of their skin
depending on its
surroundings.
18. Human
Danger…
Humans have become a
major danger for amphibians
of all types. Water pollution is
causing many deformities in
frogs as well as poisoning
them, and loss of habitat
through the building of roads
and houses.
In some countries, frog’s legs
are considered a delicacy,
which means that people love
to eat them! Eew!
(Pictured is the native Maud
Island Frog)
19. New Zealand Native
Frogs
New Zealand has 4 native frog species.
Frogs are declining everywhere in the world. More than most creatures,
frogs are sensitive to disease, pollution, chemical poisons and
environmental changes, as they absorb many things through their sensitive
skin.
New Zealand’s, Hamilton's frog (pictured) is the most critically endangered
species, with less than 300 individuals remaining.
