The document discusses exhibit design at the Milwaukee County Zoo, providing details on how exhibits are designed and engineered to be safe for both animals and visitors. Glass windows for lion exhibits are rigorously tested to withstand the force of a charging lion. Hippo viewing windows require 5 layers of strong glass. Exhibits aim to immerse visitors in natural habitats while keeping predators and prey safely separated. Design considerations are also discussed for aviaries, penguin exhibits, giraffe and orangutan enclosures, and reptile exhibits. The goal is for visitors to view animals in a safe but naturalistic environment that inspires conservation.
The document summarizes adaptations of various animals to their environments. It describes physical adaptations like shells, claws, and feathers that help leatherback turtles, polar bears, and egrets survive. It also outlines behavioral adaptations such as mating rituals and hunting techniques that allow zebras, platypuses and gray foxes to find mates and catch prey. The document covers adaptations for environments like oceans, tundra, forests, and deserts.

The zoo also features exhibits for penguins, bears, great apes, animals along the river's edge, and big cats and hoofed animals.
Bibliography Of An Argumentative Essay About ZoosBeth Salazar
Zoos have both positive and negative impacts on animals and society. Positively, zoos educate the public about wildlife and conservation, and many endangered species have been saved from extinction through zoo breeding programs. However, keeping wild animals in captivity can deprive them of freedom and natural behaviors. While zoos aim to care for animals, some question if enclosures can meet all of their complex needs. There is ongoing debate around the ethical issues of animal captivity for entertainment and public education.

The lion enclosure at Auckland Zoo is much smaller than the range lions have in the wild, and consists of grassy hills, trees, and rocks rather than the open savannah habitat lions typically live in. The climate and ability to hunt/access food and water are also very different for lions at the zoo compared to in the wild. While toys and other items are provided for stimulation, the living conditions, social structures, and behaviors of the lions differ significantly from what would be seen in the natural environment.
The giraffe enclosure also provides a habitat that diverges substantially from what would be found in the wild savannah. It is mostly bare earth with few trees, the climate and access to food/water vary greatly

10 Incredible Animals That Survived Extinction.pdfDiegoMorais62
There are many fascinating species in the world. However, a number of species are going extinct as a result of habitat loss and human activity. Then, efforts are made to find the extinct species. The last members of rediscovered species are currently being studied by scientists and conservationists for strategies to conserve them. Here are a few examples of species that were considered to have vanished only to reappear.
Warmer weather could mean more jellyfish sightings in UK waters according to experts. Jellyfish populations increase when conditions are favorable, acting as "thermometers of the oceans." Higher numbers are also expected in Spanish beach resorts. Eight types of jellyfish have been spotted in UK surveys since 2003.
- The author went scuba diving and observed octopuses in their natural habitat, which fascinated them and prompted an assignment on the morality of consuming octopuses.
- Through their observations, the author realized octopuses have highly intelligent and complex capabilities, contrary to common misconceptions that view them as unintelligent or harmless.
- The author has shifted their view to supporting octopuses due to their intelligence and sentience, rather than viewing them as mere food.
The document discusses spiders and spider silk. It describes how spiders produce silk from specialized glands to make webs, egg sacs, draglines, and more. Spider silk is remarkably strong, stronger than steel on a weight basis. The document explores how some cultures have used spider silk and discusses modern scientific efforts to recreate synthetic spider silk through recombinant DNA technology. This research aims to develop new high-performance materials. However, the Quran describes a spider's web as the "flimsiest of houses," seeming to contradict the scientific findings on silk strength. The document resolves this by explaining spiders produce different types of silk for different purposes, and the silk used in webs is weaker than dragline silk.

The town of El Valle de Antón, in central Panama, sits in the mid.docxchristalgrieg
The document describes the disappearance of amphibian populations around El Valle de Antón in central Panama. It details how golden frogs and other endemic species were once abundant in the area but have now disappeared from the wild due to an emerging infectious disease. The El Valle Amphibian Conservation Center was established to try to preserve what remains of endangered species like the Panamanian golden frog through captive breeding programs. However, many species have already gone extinct before conservation efforts could begin.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
1. Animal Exhibits
Standing within inches of a lion, the only thing between
youand hundreds of pounds of muscle, claws and fangs is
a. pa.ne of glass. Is that glass lion-proof? you wonder. It is,
indeed, says Dr. Bruce Beehler, a Deputy Director of the
Milwaukee County Zoo. "We put the windows through
rigorous lab testing. We calculated it would have to with-
stand the worst-case-scenario force of a 500-pound lion
running headfirst into the glass at 30 miles per hour; and
ire used a steel beam to simulate the force of a full-on
Themba charge." Themba is the Zo'o's adult male lion.
The thickness of glass is an obvious aspect of designing
exhibits for Zoo animals and for` safety. For Happy, a 5,500-
pound hippo, it took five layers of sturdy glass laminated
with plastic to create a viewing window, the strongest piece
of glass in the Zoo. But a lot of what makes for good exhibit
design is outside the public's view (like lab tests for glass
strength). In general, an exhibit's design should seem so
natural that visitors don't even think about it, says Dr. Beehler.
"We want them to pay attention to the animals."
Yet we thought Zoological Society members might
want to go behind the scenes and learn some of the "secrets"
to creating a great zoo. So here's a design tour just for you:
Go natural: The Milwaukee County Zoo was a pioneer
in 1961 when it opened on Blue Mound Rd. That's because
it displayed many of the animals outdoors in natural-looking
environments instead of in metal-bar cages that were used
at the Washington Park Zoo (our Zoo's predecessor). It was
another 15 to 20 years before this idea became the norm for
most modern zoos. The goal is to make visitors feel they are
in the same natural habitat as the animal. Some people call
the idea ``immersion." "The predator-prey exhibits are great
examples," says Dr. Beehler. He's referring to the Zoo exhibits
where predators seem to be in the same area as their prey
(but are actually separated by moats that zoogoers often can't
see). The seven main predator-prey exhibits are: lions over-
looking antelope and zebra, tigers and camels, cheetahs and
impala, jaguars and tapirs, polar bears and seals, Alaskan
brown bears and moose, grizzly bears and elk.
Immerse yourself: You can actually be inside an exhibit
at the Herb & Nada Mahler Family Aviary. Enter through
the aviary's east do`or, go past the penguins and you enter
the free-flight exhibit. Here you're surrounded by birds that
swoosh through the air, walk on the ground and perch on
rocks walls and in trees. And what's that smell? That's the
natural odor of birds that feed heavily on fish, says Alexwaier,
the Zoo's bird curator. Now here are some secrets of this
exhibit's design:
• Two large pumps circulate water throughout the entire
exhibit, even up high to allow for a waterfall. "The waterfall
adds to the feng shui of the exhibit," says Waier. "When
it's not working, you realize something's missing."
• All water in the exhibit is drained daily,
• Sticks and grasses are regularly placed throughout
the exhibit so birds can naturally forage for
nest-building materials.
•Naturalsunlightstreainingintotheexhibitisfromskylights.
2. Power to the penguins: Now head back to the aviary's
rockhopper and gentoo penguin exhibit. It might look like
a mere penguin aquarium, but it's actually one of the most
complex exhibits to operate. Did you know it requires:
• Two powerful chillers (and backups for safety).
One keeps the air cold. The other keeps the water cold.
• Lighting that mimics the length of daylight during Antarctic
seasonal changes. In spring the days are getting shorter
in the exhibit. "This keeps penguins in their molting
and breeding cycle," says Waier.
• Two types of water filters: a sand filter and diatomaceous
earth filter (commonly found in swimming pools).
Giraffe closeup: One important aspect of exhibit design is
economical use of space. A good example of this is the Millercoors
Giraffe Experience. In 2006 the exhibit was nearly doubled in size
by using viewer-friendly horizontal cables to separate giraffes from
the public. If moats had been used to surround the new space, there
would have been little room left for giraffes! The new design also
included a 6-foot-high viewing deck to put visitors at eye level
with the animals. The indoor quarters that housed the giraffes
were expanded to create a public
indoor space. You are now in
the same airspace as the ap
giraffes, and instead of glass
and metal mesh, the only
visual separation between
the public and the giraffes
are the cables. This provides
a much more intimate view.

Other design features:
• The indoor exhibit floor is
cushioned to give giraffes
a comfy place to lie down.
• A moveable wall inside one off-exhibit stall allows animal-care
staff to get close to giraffes safely, to provide routine medical
care and training.
• Skylights fill the indoor exhibit with natural sunlight.
Watch for flying snakes: While giraffes are the Zoo's tallest
animals, small animals like reptiles also require specially designed
exhibitsthatcatertotheirn'eeds.Considertheornateflyingsnake
exhibit in the Aquatic & Reptile Center (ARC). ``It's an arboreal
snake. So we use raised branches%to keep them above the ground,"
says Jessica Munson, ARC area supervisor. "Compare this to the
rhinoceros viper exhibit to the right, which is designed for a
terrestrial snake. It doesn't need elevated branches. So its exhibit
has few climbing places." The ornate flying snake exhibit contains
more than meets the eye, such as:
• An ultraviolet light plus a heating light to mimic the sun's
full spectrum while keeping the coldblooded reptile warm.
• Eighty-degree drinking water, which the snake prefers.
• Misters installed in the ceiling to maintain appropriate
moisture and humidity levels. "All of the reptile exhibits
have misters," says Munson.
3. Follow the direction of Jessica Munson's snake hook and
you'll see an ornate flying tree snake on a branch near the
top of the exhibit.
M.J. the orangutan detached a misting hose,
took off the nozzle and sprayed zoogoers
with water.
• The large aquariums use a special "glass" made of acrylic laminated between
two thin pieces of glass. "Acrylic is a good insulator but scratches easily," says
Craig Berg, reptile and aquarium aurator. "Glass is difficult to scratch but is a
poor insulator and fogs up easily during summer. We are one of the few zoos
to use this special type of glass."
Great-ape geniuses: Some people might call orangutans the geniuses
of figuring out how to dismantle an exhibit. These endangered great apes
possess three key traits: incredible strength, high intelligence and never
ending patience. It's understood that if a great-ape exhibit is ``orang-proof,"
it can contain any species of great ape.
Take M.J., the Zoo's female orangutan. "She's very mischievous," says Trish
Khan, Zoo area supervisor for primates. "We can't give M.J. any large branches
because she'Il immediately strip them of leaves and use them as tools and hook
items to bring them closer to her." M.J. has been known to devise tools from
blankets, sticks and leaves. Other great apes can make and use tools, too. But
"a chimp will lose patience while an orang will think and think about a problem,"
says Khan. Perhaps the most famous example of M.J. outwitting the zookeepers
was when she detached a hose from its misting nozzle and began spraying
zoogoers with water. "I had put the hose through PVC pipe and covered part
of the hose nozzle with it," says Khan. "But M.J. managed to detach it and
started spraying people, even using her fingers to create a more powerful
spray of water." Onlookers thought it was great fun.
Tight is not enough: Here are some secrets to housing the orangutans:
• Each screw inside the exhibit has a special locking nut that makes it harder
to loosen. "They can still loosen them," says Khan, "and when they do, they
hang onto them and use them to trade for treats."
• Orangutans like to swing from fire hoses and in hammocks, but everything
has to be industrial-strength. And chains and padlocks are needed to connect
hammocks to the fire hoses. If the fire hoses were tied together, the orangutans
would untie the knots.
• The floor is heated to keep these hotrmclimate primates comfortable in winter.
Animals all around you: Immersion doesn't occur only when you view
an animal in a natural exhibit. According to Dr. Beehler, a walk through the
zoological gardens is an exercise in immersion writ large. "You have flamingos
just feet away," he says. "Peacocks and peahens share the curved walkways.
Waterfowl live on placid Lake Evinrude and the ponds. It's a beautiful setting."
Plus, the+Zoo's woods include wild hawks, owls, fox, chipmunks, bats, songbirds
and more. A zoo, he adds, is more than just a collection of animals and erfuibits.
"It'speoplecomin8toseetheaniinals.Itisourjobtomakevisitorsfeelwelcome,
safe, comfortable and to give them `a sense of wonder, learning and empathy
with animals." The ultimate goal of a zoo, says Dr. Beehler, is to inspire people
o want to save the animals in the wild. Thus, zoo exhibits and their myriad
are a means to that noble end.
