Metamorphosis
This document discusses insect metamorphosis. It explains that there are two types: incomplete metamorphosis, which has three stages (egg, nymph, adult), and complete metamorphosis, which has four stages (egg, larva, pupa, adult). Incomplete metamorphosis involves an insect growing gradually from nymph to adult, while complete metamorphosis involves a dramatic physical change between life stages. Examples of insects that undergo each type of metamorphosis are provided.
BIOLOGY
This document provides a lesson plan and content for a unit on mammalian diversity. The lesson plan outlines 5 lessons covering introductions to the three major lineages of mammals, their phylogenetic relationships, primates, living primates, and a unit test. The content section defines key terms like monotremes, marsupials, eutherians, and describes characteristics and examples within each group. It also discusses primate characteristics and adaptations, provides classification of living primates into 3 main groups, and depicts phylogenetic trees of primate and mammal relationships. Diagrams are included to illustrate concepts.
Western lowland gorillas by isaiah fipps
Western lowland gorillas live in troops of up to 30 individuals in the rainforests of Central Africa. Each troop is led by a dominant silverback male who organizes the group's activities as they travel within their home range. Female gorillas give birth to one infant after a 9 month pregnancy and carry their young on their backs for the first few years. Gorillas communicate through displays of strength from the silverback and generally avoid conflict unless disturbed. They eat a variety of plant parts and fruits found in their native habitat.
Immature stages of insects and Its types (Classification)
Life cycle of an insect can be complete or incomplete which posses different stages in the biology. If it is complete metamorphosis, it consists of egg, larvae, pupa and adult or incomplete metamorphosis with egg, nymph and adult. In the case of insects with complete development show complete metamorphosis with all immature stages that vary in size, shape and form or structure i.e., egg larvae and pupae differing each individually. Hence, different types of egg, larvae and pupae are described in this PPT (Basic Classification)
Mammals 10 4-roumenova_bojkov_damyanov
This document provides information about mammals in 3 paragraphs or less. It discusses key mammalian characteristics like mammary glands, hair, and differentiated teeth. It also outlines mammalian reproduction, noting placental and non-placental types. Finally, it briefly explores human interactions with mammals like eating them, obtaining dairy, and using fur.
Bees!
There are over 20,000 known species of bees that play a vital role in pollinating many important food crops through transporting pollen from plant to plant. Honey bees live in large colonies consisting of a single queen, many female worker bees, and male drones. The queen lays eggs and produces pheromones to control the hive, workers care for larvae, collect nectar and pollen, and produce wax for the hive. Drones exist only to mate with queens. Bees communicate through dancing and scents, and their wings beat over 11,000 times per minute, producing their distinctive buzz.
Ant ppt
The document discusses various topics related to ants. It begins by describing the anatomy of ants, including their three body segments - the head, mesosoma, and gaster. It then discusses ant colonies and their social structures, noting they have different jobs based on age. Some ants cultivate fungi or store food. Fire ants are described as invasive in the US, with reddish bodies and venomous stings. The document concludes with examples of forensic uses of pavement ants and possible human-caused ant deaths.

Froggys
Amphibians like frogs and toads are some of the earliest living vertebrates that evolved during the Devonian period. Many amphibian types went extinct over time, but those still living today include frogs, toads, salamanders and newts. Frogs are commonly used in laboratories to study anatomy, behavior and evolution. Their reproduction involves external fertilization of jelly-like eggs. As tadpoles, they have tails and gills but later develop lungs and legs to live on land as adults. Frogs play an important role as predators in the food chain, eating insects.

Mammals
Mammals are named after their mammary glands, which produce milk to feed their young. They are classified into three main groups: monotremes, which lay eggs; marsupials, which carry their young in pouches; and placentals, which carry young in the womb. Placental mammals are further divided into 11 orders based on characteristics like diet, habitat, locomotion and teeth. Some key orders include insectivores, bats, rodents, rabbits, armadillos, whales, dugongs, elephants, carnivores like dogs, hoofed animals, and primates.
Social behavior in termites
Termites live in complex colonies found in regions around the world. They communicate chemically through pheromones and live in castes that work cooperatively. The colonies contain a king and queen that lay eggs, supplementary royalty, wingless workers that build and maintain the nest, soldiers that defend the colony, and proboscideans that have elongated heads. Termites digest wood and plant material with the help of symbiotic protozoa.
Morphology and adaptations of immature stages of hemiptera
A guide to the fascinating world of hemipteran insects which includes bugs, hoppers, scales and sucking insects (with pictures)
what is pupa.?
Pupa is the inactive life stage that occurs between larva and adult for insects that undergo complete metamorphosis. During the pupal stage, the larval structures break down and adult structures grow from imaginal discs. Pupation allows the insect to transition from its larval form to its adult wings and other structures. The pupa is non-feeding and usually motionless. When development is complete, the adult insect emerges from the pupal case by splitting it open. The duration of the pupal stage varies between species and depends on temperature.
Metamorphosis, Diapause and its types; immature stages of insects
1. The document discusses metamorphosis, diapause, and immature stages in insects. It describes the different types of metamorphosis including ametamorphosis, hemimetabolous, and holometabolous.
2. It explains diapause as a period of arrested development and lists examples of diapause occurring in different insect life stages. Facultative and obligatory diapause are also described.
3. The types of eggs laid by insects are outlined, including singular eggs and egg masses. Different immature stages are also covered, such as larvae, nymphs, and their characteristics.
Insect metamorphosis
This document discusses the different types of metamorphosis, insect eggs, larvae, and pupae. There are four main types of metamorphosis: ametabola (no metamorphosis), hemimetabola (incomplete metamorphosis), paurometabola (gradual metamorphosis), and holometabola (complete metamorphosis). Insect eggs can be laid singly or in groups, and come in different shapes and structures. Larvae are generally oligopod, polypod, or apodous. Pupae fall into the categories of obtect, exarate, or coarctate. The document provides examples and details on the characteristics of each type
B34 ppt primate evolution ch 16
Primates evolved over time, developing traits like opposable thumbs and binocular vision. Early hominids like Australopithecines exhibited traits of both apes and humans, while later groups including Homo sapiens, Neanderthals, and Cro-Magnons showed increasingly human-like characteristics. Primate evolution involved adapting to life in trees as well as walking on two legs.
Origin and Evolution of Mammals
The document discusses the origin and evolution of mammals. It describes two main theories for the ancestry of mammals - through amphibians or reptiles. While amphibian ancestry was proposed, reptilian ancestry is now widely accepted based on fossil evidence. Many characteristics of early mammal-like reptiles called therapsids were mammalian. True mammals first appeared in the Jurassic period but remained small until after the extinction of dinosaurs. When ecological niches opened up in the Cenozoic era, mammals underwent adaptive radiations into various forms through modifications of limbs, teeth and other features for different habitats like trees, ground, burrows, water and air. Convergent evolution also led to similarities between unrelated mammals adapting to the same nic
Musth In Elephants
Musth is a periodic condition in male elephants characterized by highly aggressive behavior and increased reproductive hormones. During musth, an elephant's testosterone levels can increase up to 60 times normal levels. Elephants in musth become unpredictable and dangerous as they seek out females in estrus. Proper management of musth elephants requires chaining them securely during this time to prevent potential attacks on humans or other elephants.
233 prosimians
1. The document discusses the taxonomy and characteristics of several primate families found in Madagascar, Africa, and Asia, including lemurs, lorises, galagos, pottos, and tarsiers.
2. Many species are nocturnal and solitary foragers, while others live in pairs or groups. Diet varies but includes insects, fruit, and gum/resin.
3. Many species are threatened by habitat loss and face an uncertain future unless conservation efforts are improved.
Insect’s development
This document defines key terms related to insect growth and development stages. It describes the three main types of metamorphosis - hemimetabolous (incomplete), holometabolous (complete), and ametabolous (no change). Complete metamorphosis involves four distinct stages - egg, larva, pupa, and adult. Incomplete metamorphosis involves nymphs that resemble adults. The document provides examples of insects that undergo each type of metamorphosis and describes the characteristics and functions of each life stage.

A for ant
Ants are social insects that live in colonies and have evolved over 100 million years. There are over 12,000 known ant species worldwide. Ant colonies consist of a queen, workers, sometimes soldiers, and males. The queen lays eggs while workers feed and care for larvae. Ants go through life stages of egg, larva, pupa, and adult. They have an exoskeleton, antennae, and jaws. Leafcutter ants cultivate fungus by cutting leaves and growing fungus gardens underground.

Termites colony and society
Termites live in highly organized colonies with different castes. Workers forage for food and feed other members. Soldiers defend the nest. Reproductives are winged or wingless. Colonies communicate chemically through pheromones to coordinate tasks and defense. When mature, winged reproductives swarm and shed wings to start new colonies.
Vertebrates and invertebrates
Animals are grouped into two categories: vertebrates, which have a vertebral column or backbone, and include animals like camels, crocodiles, ducks, elephants, giraffes, frogs, lions, rats, snakes, and turtles. The second group is invertebrates, which do not have a backbone and includes animals such as bees, ants, cockroaches, house flies, prawns, jellyfish, crabs, butterflies, octopuses, snails, worms, and starfish.
Type of larvae and pupa in insect
This document discusses the different life stages of insects: eggs, larvae, and pupae. It describes the various types of eggs insects lay, such as sculptured, rounded, floating, pedicellate, ootheca, egg rafts, and egg pods. The document outlines the three main types of larvae - oligopod, polypod, and apodous - and provides subtypes examples. It also discusses the three types of pupae: obtect, exarate, and coarctate. The pupal stage is usually inactive and enclosed in a protective cocoon.

Carcass
Carcass beetles, also known as hide beetles, are scavengers that feed on the dry remains of dead animals. They have a bumpy, warty appearance and can hide by covering themselves with dirt. Carcass beetles are found worldwide and include over 300 species. They are important in forensic investigations, as their presence on burned bodies can help estimate time of death. Rove beetles and carrion beetles also assist in estimating the post-mortem interval based on their life cycles and presence at carcasses at different stages of decomposition. Both larvae and adults of these beetle families feed on carrion and maggots.

The platypus uses its sensitive snout to detect tiny movements of prey in rivers and streams, as its skin covers its eyes and ears when it dives. It is one of few mammals that lays eggs. Wallabies are marsupials where tiny babies live in their mother's pouch to feed and grow until around 10 months old. Dolphins are powerful swimmers that can reach speeds over 20 mph with their streamlined shape, strong tail flukes, and steering flippers, though they usually swim at 5 mph. Bats have built-in radar called echolocation that helps them fly and hunt in darkness by emitting high-pitched noises.
Cool things about insects!
Insects have a three-part body, three pairs of legs, compound eyes, and one pair of antennas. Their compound eyes are made of thousands of tiny lenses that allow them to see 360 degrees, though not details. Insects lay eggs in various locations and have life cycles from one day to 50 years. They use camouflage and mimicry, and come in a wide range of sizes and populations. While some insects are harmful, many are beneficial as pollinators, and their study contributes to our understanding of biodiversity.
Comparative study of life history strategies in HEMIMETABOLA INSECTS
This document summarizes the life cycles of several hemimetabolous (incompletely metamorphosing) insects including cockroaches, grasshoppers, stick insects, praying mantises, termites, dragonflies, and damselflies. It describes the key stages of egg, nymph/naiad, and adult for each group. Reproduction, development, and defenses at each life stage are discussed. Diagrams illustrate the life cycles and differences between dragonfly and damselfly naiads and adults. The genetic and physical bases of adult coloration and behavioral defenses of naiads are also summarized.
5.Baunc.Spiders
Spiders have an abdomen and cephalothorax, eight legs with seven segments each, and pedipalps on their heads. They digest liquidized food that they get by pumping enzymes into prey or grinding food with their pedipalps. Males transfer sperm to females through a courting process. Spiders breathe through book lungs or tracheal systems and have various sensors like eyes and hair to navigate their environment. They are important for controlling insect populations.
Butterflies2
Butterfly wings are made of a thin membrane covered with colorful scales that provide strength and stability. A butterfly's scales are pigmented to produce various colors and patterns. During development, butterflies go through stages as an egg, larvae, pupa, and finally adult. As adults, butterflies use their wings and flight to search for mates, food, and migrate. Their colorful wings and patterns provide camouflage and warnings to deter predators.
Rabbits
Rabbits are small mammals found worldwide in habitats like meadows, woods, and grasslands. There are over 50 rabbit species, including European rabbits known for living in underground burrows. Rabbits have powerful back legs for hopping, large ears for detecting predators, and eat plant matter through a digestive process of excreting two types of feces - one which is immediately reingested to further extract nutrients.
Monarch Butterflies
Monarchs go through four life stages: egg, larva, pupa, and adult. As larvae, they molt five times before forming a chrysalis. Inside the chrysalis, the caterpillar transforms into an adult butterfly. Adult monarchs have black veins that help them glide and migrate. Each fall, monarch butterflies migrate thousands of miles from the northern United States and Canada to spend the winter in central Mexico, returning north in the spring to lay eggs and repeat their life cycle.
How young animals grow up?
Young animals grow up
If the zygote can grow in and interact with a suitable environment, it contains all the information required to create a new organism. It stands to reason that some aspects of embryology must be considered when studying the development of behaviour. For instance, the way the nervous system's fundamental structure is built, but we must go much further than this.
Young animals grow up
It is entirely possible to argue that in some animals, behavioural development continues throughout life. Long after an animal is independent, its behaviour may still change. Learning could therefore be seen as a form of development, and young animals occasionally learn a lot as they grow. But in this section, we'll focus on other behavioural changes that frequently occur early in life, often quickly and dramatically.
It is important to understand that young animals must always be fully functional creatures capable of acting appropriately in their own worlds. They cannot simply be incomplete creatures or inadequate stages on the path to adulthood.
Some animals are protected during their early development by an eggshell or uterus or by watchful parents, but others are free-living and must care for themselves completely. Young animals may develop into miniature adults as they grow in size over time, but in order to keep up, their behavioural responses must also adapt.
Although young cuttlefish (Sepia) start out and continue to be carnivores, at first, they can only kill tiny crustacea that are disregarded as prey once the cuttlefish has grown. As they grow closer to adult size, they move on to food that is bigger and bigger, which requires a change in the behaviour patterns used to find and catch prey.
Even more drastic behavioural and morphological changes may occur in some cases because some young animals live entirely different lives than do adults. Tadpoles are herbivores that swim and breathe like fish before changing into land-dwelling carnivorous frogs or toads.
Eristalis tenax, an aquatic filter-feeding rat-tailed maggot that breathes through a long snorkel tube at its back, transforms into a flower-feeding hoverfly (see Fig. 2). Young and adult require almost entirely different behavioural repertoires for these life histories.
Rat-tailed maggot | Flower-feeding hoverfly
These alterations mean that development frequently has to produce patterns that only function for a portion of an animal's life before disappearing. The specific coordinated movements that cockroaches use to emerge from their individual eggshells as well as the protective case that bundles a group of eggs together were both described by Provine in 1976. These movements, which are only observed on this one occasion, consist of a series of reversed waves of contraction along the body from the tail to the head.
They appear at the exact right time, at the end of the egg stage's development, and are used to propel the young cockroach nymph into the following growth

This document provides an overview of honey bees and apiculture (beekeeping). It discusses the composition of honey bee colonies including the queen bee, drone bees, and worker bees. It describes the life cycle and development of honey bees from eggs to larvae to pupae. Key aspects of beekeeping covered include the history of scientific study of bees, common bee species, honey extraction methods, and bee pasturage (plants used for nectar and pollen).
Chapter 26 notes Arthropods.ppt
Arthropods are invertebrates with segmented bodies and jointed appendages that include insects, arachnids, crustaceans, and others. They have an exoskeleton, a segmented body, and bilateral symmetry. Arthropods have well-developed senses including compound eyes, taste and smell receptors. They undergo molting to grow, have open circulatory systems, and many reproduce sexually with internal or external fertilization. The largest class is Insecta, which undergo complete or incomplete metamorphosis from egg to adult.
Butterfly
This is my first slide show presentation in IT1 subject and it is entitled BUTTERFLY. I hope for those people who wants to able to view i wish you will like it.
Prehensile Tail Research Paper
This document summarizes a research paper on prehensile tails. It discusses how prehensile tails are an adaptation that helps creatures thrive by allowing them to grasp objects. While many monkeys share a common ancestor and have prehensile tails, the structure of tails differs between reptiles and fish who also possess them, suggesting they evolved separately. Prehensile tails are an example of an analogous adaptation rather than a homologous one.
Insect metamorphosis
This document discusses the different types of metamorphosis, insect eggs, larvae, and pupae. There are four main types of metamorphosis: ametabola (no metamorphosis), hemimetabola (incomplete metamorphosis), paurometabola (gradual metamorphosis), and holometabola (complete metamorphosis). Insect eggs can be laid singly or in groups, and come in different shapes and structures. Larvae are generally oligopod, polypod, or apodous. Pupae are either obtect, exarate, or coarctate. The document provides examples and details on the characteristics of each type.
Aerial mammals.pptx
This document discusses different types of aerial locomotion in animals, including gliding and flapping flight. It provides examples of gliding mammals like flying squirrels and flying lemurs that can glide between trees. Their bodies are adapted with parachute-like membranes between their limbs that allow gliding. The document also describes bats as the only true flying mammals that flap their highly adapted wing membranes to fly. Bats have skeletal, muscular and sensory adaptations like echolocation that allow sustained flapping flight and navigation in darkness.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation

Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

- 1. Strange events Chapter 14 50 Misclaneous MOBILITY One characteristic feature of animals is their motility or mobility ; In fact over millions of years they have evolved many varieties of means of moving around to suit their respective circumstances ; And some of them display really very interesting and notable ability. NOTABLES The caterpillars of moths and butterflies have 3 pairs of true legs called ‘ walking legs’ at the front (on thorax) and 6 pairs of false feet at the back (on abdomen) to move in a rippling fashion ;some even spin a carpet of silk to help them to move over smooth surfaces .
- 2. Strange events 51 STRANGE MAMMALS Mole rat is a mammal that behaves like a bee living in underground colonies dominated by a queen which alone gives birth to young ,others acting as subordinates looking after her and her babies like worker bees and capable of excavating in a regimented way . DUCK BILLED PLATYPUS is a mammal that lays eggs. Kangaroo is one which nurtures semi developed embryo in an external pouch .
