The document provides a comprehensive overview of possums in Canberra, Australia, including their biology, behavior, role in the ecosystem, and the issues caused by them entering urban roofs. It discusses how possums are attracted to roofs for shelter and food sources. While possums are celebrated in Canberra, their presence in roofs can lead to structural damage through gnawing, scratching and nesting. The document examines factors that influence possum infestations and provides tips for humane management and coexistence between possums and humans in the city.
Raccoons are omnivorous nocturnal mammals that are well-adapted to urban environments where they find food and shelter. They can cause damage by entering attics and chimneys to nest, and by feeding on garden fruits and vegetables. Management of raccoon problems involves habitat modification to reduce food and shelter, exclusion methods to block access to buildings, and trapping by professionals when needed. Raccoons are intelligent animals that can learn to avoid scare devices and repellents.
Several species of carpenter ants can damage wood structures. The document identifies the two most common in California, Camponotus modoc and Camponotus vicinus, which construct extensive tunnel networks that can compromise structural integrity. It provides details on identifying characteristics, colony dynamics, damage signs, and integrated pest management strategies for prevention and control. Nonchemical approaches include exclusion, sanitation and moisture control, while chemical treatments involve locating nests and applying baits or insecticides directly into galleries.
The Economic Importance of the Diatoms - 1917 Albert MannNualgi.org
This document discusses the economic importance of diatoms, which are microscopic algae. It summarizes several uses of diatoms, including as a polishing powder due to their high abrasiveness, in toothpowder due to their abrasiveness, as an additive to extend flour for starving people, and most importantly as an absorbent in the production of dynamite. It also notes their value in oceanography for determining ocean currents due to their ability to be transported long distances while retaining characteristics indicating their origin.
Australian Indigenous Architecture -Its Forms And EvolutionAndrew Molina
This document summarizes the evolution of Aboriginal architecture in Australia from pre-colonial times to the present. It identifies three major periods: (1) classical Aboriginal architecture prior to colonization, characterized by impermanent shelters adapted to local environments and weather; (2) acculturated architecture from the 19th-20th centuries, as Aboriginal people incorporated new materials into pastoral, mission and settlement camps while retaining cultural practices; and (3) outstation architecture from the 1970s onward, including self-constructed town camps made of scrap materials that maintained Aboriginal identity and autonomy despite poverty. The document examines shelter types, construction techniques, spatial organization and cultural meanings across these periods to argue that Aboriginal architecture constitutes an evolving tradition challenging non
Though not considered an immediate risk to museum collections, subterranean termites are a significant pest for historic structures. Termite colonies can cause extensive damage before being noticed, ranging in size from a few hundred to several hundred thousand termites. Control efforts are challenging due to factors like termite adaptability, building intricacies, and limitations of control methods. Colonial Williamsburg takes a holistic approach to minimize termite damage to over 600 buildings, using in-house and contract resources categorized by risk and priority.
The document discusses possums in Canberra, Australia. It aims to dispel the common misconception that possums attack humans by exploring their behavior and interactions with people. Possums are actually gentle, timid creatures that avoid conflict and pose minimal threats. While rare conflicts can occur if possums feel threatened, understanding their behavior can promote peaceful coexistence. With simple steps like managing food sources, residents can safely share urban spaces with these marsupial neighbors.
Slugs damage many common garden and ornamental plants, leaving large ragged holes. The most damaging slugs in western Washington are the grayish Deroceras reticulatum and the 3-4 inch long orange to black Arion ater. Slugs lay small clusters of 1/8-1/4 inch eggs that hatch after a few weeks. Cultural controls like removing habitat, trapping, and barriers such as copper fencing around plants are most effective at reducing slug populations. Chemical controls should be a last resort due to risks to pets and wildlife.

Increasing amounts of plastic pollution in oceans is allowing barnacles to disperse to new areas by hitching rides on floating plastic debris. Barnacles can survive for much longer on plastic rafts compared to natural rafts like wood or plants. This plastic-assisted dispersal has already led to at least one barnacle species becoming invasive. Areas most at risk of invasion are the tropics and southern pole, where plastic pollution is introducing non-native species that could overrun endemic wildlife. Studies have found barnacles frequently colonizing plastic debris along coastlines. To reduce further dispersal, efforts should focus on reducing sources of plastic pollution entering the oceans.

Biology transport in animals and plants by dr. martin otundo richardMartin Otundo
This document discusses transport in plants and animals. It begins by explaining that transport is the movement of substances within an organism and that both excretory products and nutrients need to be transported for cells to survive. Higher organisms have more complex transport systems compared to simpler organisms like amoebas where diffusion plays a larger role due to their large surface area to volume ratio. The document then focuses on different transport systems in plants, including uptake of water and minerals in roots and long distance transport through vascular bundles. It describes the roles of xylem and phloem and processes involved like transpiration.
This document provides information on identifying and managing common garden snails and slugs. It discusses the most common snail and slug pests in California gardens, including the brown garden snail and gray garden slug. It describes their life cycles, feeding behaviors, and ideal hiding places. The document recommends an integrated pest management approach using multiple control strategies, such as removing hiding places, choosing resistant plant varieties, handpicking, traps, barriers, and baits as part of a cultural control program.
This document discusses various ways that insects have inspired and influenced human culture. Some key points include:
- Insects have historically been an important food source for humans and are still eaten in many cultures today.
- Designs for products like water bottles and buildings have been inspired by how insects collect water or regulate temperature.
- Advances in solar panels and tires have been influenced by studying butterfly wings and honeycomb structures.
- Insects have also inspired art, fashion, weapons development, and even helicopter design. Their intricate biological systems continue to amaze scientists.

Deer can damage gardens and landscaping by eating plants and rubbing their antlers on trees. The document discusses deer biology and behaviors, as well as methods for deterring deer such as fencing, repellents, and planting deer-resistant plants. Fencing is the most effective exclusion method, with fences needing to be 7-8 feet tall or taller on slopes. Individual plant protectors can also be used to shield small trees or shrubs. Regular inspection and repairs are important to maintain fence and protector effectiveness over time.
ANTI-TERMITE TREATMENT: NEED OF CONSTRUCTION INDUSTRYA Makwana
Termites popularly known as white ants cause considerable damage to wood works,
furnishing etc. of buildings. The Latin name Isoptera means "equal wing" and refers to the
fact that the front set of wings on a reproductive termite is similar in size and shape to the hind
set. Termites are social and can form large nests or colonies, consisting of very different
looking individuals (castes). There are more than 2,500 different types of termites in the world.
In some country the loss caused due to termites is estimated to be as high as 10% of the capital
outlay of the building. Anti-termite treatment is therefore necessary so that damages are either
reduced or stopped together. Through regular inspections, a termite specialist can help
identify common hot spots for activity and warning signs for a termite infestation, plus share
tips to help keep termites at bay. Termites can fit through cracks as thin as an average business
card (1/32 inch) so proper maintenance is crucial to seal up any gaps around the foundation
and roof/eaves. To identify the termite and its uniqueness, the life cycle of termite is necessary
to understand. Anti- termites are used to combat the problem. There are combinations of
methods depending on what sort of damage is done by the termites. The treatment has to be
implemented at the time of construction for effective and permanent solution.
ANTI-TERMITE TREATMENT NEED OF CONSTRUCTION INDUSTRYScott Faria

Methods discussed include pre-construction site preparation, soil treatment, and installing structural barriers.
Carpenter ants seminar work by Uwamose martinsUwamose MNO
Carpenter ants are social insects, with colonies made up of several different forms or “castes”. They are so-called carpenter ants because of their habit of chewing wood to create nest sites. They do not eat wood, like termites, but excavate it with their strong, saw-like jaws to create random galleries where they nest. They play ecosystem roles particularly by aiding in the decomposition of decaying tees. Carpenter ants belong to the subfamily Formicinae (Genus: Camponotus)

17) M.Here you see several examples of fossil mollusks. Mollusks are one of the most successful animal groups and include animals such as clams, snails, octopus, and squid. They have a large muscular foot and often secrete protective shells. M1. Examine the two fossil bivalves (clams). Both of these animals live by filtering food out of the water while sitting either on the seafloor or buried in the sediment. Why might burrowing help a clam? If a clam was sedentary and sitting exposed on the sea floor, what adaptations would be useful? M2. Examine the three fossil snails. Snails can fill many different roles within an ecosystem including scavenger, predator, herbivore, and even parasite. Which of these three shells is most likely to be a predator? Why did you come to that conclusion? M3. Now look at the two fossil ammonites, which are an extinct group of mollusk. These are relatives of squid and octopi that had elaborate shells with internal chambers, which can be seen in the specimen preserved as a mold. Examine the shape of the internal chambers, what function could the internal chambers serve? (make a hypothesis).
18) Sample N. Here are examples of Lophophorates including brachiopods (shells) and colonial bryozoans (stick-like). These are both animals that were extremely abundant in ancient oceans, but are much less common today. They are grouped together based on sharing a soft-tissue tentacled structure surrounding their mouth called a lophophore. Students often confuse these organisms with other animals (clams or coral), what features can you see that separate them from these groups?
19) Sample O. Arthropods (insects, spiders, crabs, and others) are the most diverse group of animals on the planet today. They have a distinctive exoskeleton and segmented bodies. Their exoskeletons are composed of chiton, which is an organic material rather than a mineral (protein). How would a skeleton made of protein alter their chance to become a fossil? Examine these examples of fossil trilobites, which are an extinct group of marine arthropods. They are common fossils in ancient rocks compared to other arthropods. Why might that be?
20) Sample P. These are examples of fossil echinoderms (sea stars, sea urchins, and relatives). Echinoderms have an internal skeleton, a variation on 5-fold symmetry, and a water vascular system with tube feet (used for locomotion and feeding). P1: These are examples of crinoids (feather stars or sea lilies). These animals are often confused with plants, but they are animals that filter the sea water with delicate arms. Think of them as a starfish atop a long stem. Crinoids were extremely abundant in the past, but are rare in the ocean today. Their stems could range in length from a few inches to over 100 feet! Why might a long stem benefit a filter feeding marine organism? P2: These are two examples of fossil echinoids, including sea urchin and a sea biscuit. Examine the sea urchin and notice it is covered with bumps wher.

harmoniously with these endearing creatures.
The Fascinating Life of Possums.
A. Exploring the Possum Species in Canberra
Canberra is home to various possum species, each with its unique characteristics and
habitats. Common possum species found in the region include:
● The Common Brushtail Possum (Trichosurus vulpecula).
● The Sugar Glider (Petaurus breviceps).
● The Greater Glider (Petauroides volans).
Understanding the diversity of possum species in Canberra is essential for appreciating
their role in the local ecosystem and their adaptation to urban environments.
The Common Brushtail Possum, for instance, is one of the most iconic and widely
recognized possum species in Canberra. Its bushy tail and grayish fur make it a
frequent visitor to suburban gardens and parks. On the other hand, sugar Gliders are
smaller and have a remarkable ability to glide through the air, making them a captivating
species to encounter.
B. Adaptations and Survival Strategies
Possums have evolved remarkable adaptations and survival strategies that have
allowed them to thrive in both natural and urban environments. From their unique
3. dentition for omnivorous diets to their prehensile tails for climbing, possums have
various biological features that make them highly adaptable and resourceful creatures.
One of the most striking features of possums is their dentition. They have sharp incisors
and molars that are well-suited for an omnivorous diet. This means they can feed on
various foods, including leaves, fruits, insects, and even small vertebrates. Their
adaptability in diet is a key factor in their ability to thrive in diverse environments.
C. The Role of Possums in Ecosystems
Possums play a crucial role in Canberra’s ecosystems. They are seed dispersers,
helping to regenerate native vegetation by spreading seeds through their feces.
Additionally, they serve as prey for various predators, contributing to the intricate web of
interactions within the local food chain. Understanding the ecological importance of
possums sheds light on the need for responsible coexistence in urban areas.
Moreover, possums are a valuable food source for predators such as owls, foxes, and
domestic cats. Their presence in the food chain helps maintain the balance of
predator-prey relationships in the ecosystem.
Peculiar Habits of Possums in Urban Areas
A. Why Do Possums Enter Roofs?
The question of why possums seek shelter in roofs and buildings is common. We will
explore the various factors that drive possums to invade urban structures, including
protection from predators, temperature regulation, and the availability of food sources.
Possums enter roofs primarily for shelter and protection. In their natural habitat, they
nest in tree hollows, but they often find roofs and attics suitable alternatives in urban
4. areas. These enclosed spaces offer protection from predators such as foxes and
domestic cats, making roofs attractive for possums seeking safety.
B. Attracted to Urban Delights: Food, Water, and Shelter
Urban environments offer possums an array of resources. From fruit trees in gardens to
open garbage bins, possums can access abundant food sources in cities.
C. Climbing Abilities: How Possums Gain Roof Access
Possums are renowned for their exceptional climbing abilities. We will discuss how
these marsupials navigate urban landscapes and access roofs, shedding light on their
agility and adaptability.
Possums are built for climbing and are incredibly agile when navigating trees, buildings,
and other structures. Several key features facilitate their climbing prowess:
1. Prehensile Tails: Possums possess long, prehensile tails that are highly flexible
and muscular. These tails act as a fifth limb, providing balance and grip when
climbing.
2. Sharp Claws: Possums have sharp claws that allow them to grip onto surfaces
effectively. These claws are handy for scaling trees and vertical surfaces like
walls and roofs.
3. Strong Hind Limbs: Their powerful hind limbs enable them to leap from branch
to branch and make agile jumps. This strength in their hind legs is also crucial for
their gliding abilities in species like the Sugar Glider.
4. Nocturnal Vision: Possums have adapted to low-light conditions and possess
excellent night vision, helping them navigate in the dark when they are most
active.
These adaptations make possums highly proficient climbers, enabling them to easily
access roofs and attics. Their ability to scale walls and roofs makes them particularly
challenging to deter once they have established a presence.
5. Understanding the Potential Damage Caused by Possums.
1. Structural Impact on Roofs
● Gnawing and Scratching: Roof Material Damage
Possums have sharp teeth, and they aren’t shy about using them. They may gnaw on
roof materials, including wood, shingles, and metal. Over time, this behaviour can lead
to significant structural damage, compromising the integrity of roofs.
The constant gnawing and scratching of possums can result in unsightly holes and
weakened roofing materials. In some cases, this damage can lead to water leaks,
which, if not addressed promptly, can cause further harm to the structure of the building.
● Damaged Gutters and Downpipes
Possums are known to explore and chew on various parts of a roof, including gutters
and downpipes. Their activity can lead to blockages and damage, potentially causing
water runoff issues during rainfall.
● The Risk of Water Leaks and Mould
Roof damage caused by possums can create entry points for water, especially during
rainstorms. Water leaks can lead to dampness and moisture accumulation within the
building’s structure.
2. Disrupted Insulation and Electrical Wiring
6. Possums nesting in roofs can disrupt insulation, reducing energy efficiency in homes.
Moreover, they may gnaw on electrical wiring, posing serious fire hazards.
Possums are known to make nests in roof cavities, often using available insulation
materials for bedding. This nesting behavior can compress insulation, reducing its
effectiveness and leading to increased energy consumption for heating and cooling.
Furthermore, possums occasionally chew on electrical wiring found in roof spaces. This
poses nums can carry various pathogens, including parasites and bacteria, that pose
health risks to humans. We will explore these health concerns and ways to mitigate
them.
1. While possums are not typically carriers of diseases that directly harm humans,
they can be reservoirs for parasites and pathogens that may pose health risks
under certain conditions.
Homeowners must take measures to prevent and address possum infestations to
minimize the health risks.
Assessing the Significance of Possum Damage in Canberra.
A. Prevalence of Possum Infestations
To understand the scope of the problem, we will examine the prevalence of possum
infestations in Canberra, drawing from local reports and data.
Possum infestations in Canberra are not isolated incidents; they are relatively common
due to the coexistence of urban and natural environments. The prevalence of possum
infestations can vary depending on factors such as the season, geographic location,
and the availability of suitable nesting sites.
7. B. Roof Types and Vulnerability to Damage
Certain roof types and materials may be more susceptible to possum damage. We will
explore which roofs are most vulnerable and why.
The vulnerability of roofs to possum damage can depend on several factors, including:
1. Roof Material: Some roofing materials, such as wooden shingles or tiles, may be
more prone to damage than metal or concrete roofs. Possums can easily scratch
and gnaw through wooden materials, making them more susceptible to
infestations.
2. Access Points: The design and condition of a roof can influence possum
access. Roofs with multiple entry points, gaps, or openings are more likely to be
invaded.
3. Proximity to Natural Habitats: Homes located near natural habitats or green
spaces where possums dwell are at a higher risk of infestation. Possums often
venture into nearby residential areas in search of food and shelter.
4. Roof Accessibility: The ease with which possums can climb and access a roof
also plays a role. Homes with overhanging branches, adjacent trees, or walls that
provide a foothold for climbing are more vulnerable.
5. Seasonal Patterns: Possum infestations may be more common during specific
seasons. For instance, possums may seek out secure nesting sites during
breeding seasons, increasing the likelihood of roof infestations.
Understanding these factors can help homeowners assess their risk of possum
infestations and take proactive measures to prevent them.
