Despite their growing urban populations, seagulls are considered endangered in the UK. Seagulls are monogamous and mate for life, returning to the same nesting sites every year. They have several adaptations that help them thrive, including the ability to excrete salt via glands above their eyes after drinking seawater, sharing incubation duties, and possessing superior night vision compared to humans.

Clarias batrachus, commonly known as the walking catfish or Thai catfish, is a species of air-breathing catfish. Here's some information about the reproduction, breeding techniques, hormonal usage, and related aspects of Clarias batrachus:
1. Sexual Dimorphism: Male and female walking catfish can be distinguished based on certain physical characteristics. Males tend to have a larger size, broader head, and more prominent spines on their pectoral fins compared to females.
2. Breeding Conditions: Walking catfish are known to breed during the rainy season or when there is an increase in water levels. They typically prefer warm water temperatures.
3. Spawning Behavior: Walking catfish are nest builders, and males exhibit paternal care. The male constructs a nest by digging a depression in the substrate, often in muddy areas or among aquatic vegetation.
4. Hormonal Induction: In aquaculture settings, hormonal induction is commonly used to synchronize and stimulate breeding in walking catfish. Hormones like human chorionic gonadotropin (hCG), luteinizing hormone-releasing hormone analogs (LHRHa), or synthetic hormone analogs are used to induce ovulation in females and spermiation in males. The dosage and timing of hormone administration depend on factors such as fish size, maturity, water temperature, and breeding objectives.
5. Breeding Tank Setup: Prepare suitable breeding tanks or ponds for walking catfish reproduction. The tanks should have appropriate water conditions, including a temperature range of 25-30°C (77-86°F), pH around 7, and good aeration to ensure oxygen supply.
6. Hormone Injection: Hormonal injection is typically performed on female walking catfish to induce ovulation. The hormone is administered through intramuscular or subcutaneous injections. It is important to handle the fish carefully during the injection process to minimize stress and ensure proper dosage delivery.
7. Spawning Technique: After hormone injection, the female walking catfish is introduced into the male's nest. The male initiates courtship behavior by circling, nudging, and wrapping his body around the female. This stimulates the release of eggs by the female and sperm by the male for fertilization.
8. Nest Construction and Preparation: Male walking catfish construct nests by excavating depressions in the substrate. They may create tunnels leading to the nest for protection. Nests are usually built in shallow waters, often in muddy areas or among aquatic vegetation.
9. Egg Collection and Incubation: Once the eggs are fertilized, they adhere to the nest walls. The male walking catfish guards the nest and ensures adequate oxygenation of the eggs by fanning them with his pectoral fins. During incubation, maintain suitable water conditions and temperature for the eggs to develop.
Larval Rearing: After hatching, the walking catfish larvae have external gills and can breathe atmospheric air. Provide appropriate rearing conditions, including water quality, temperature.
BIOLOGY OF DUGONG Dugong dugon, also known as sea cows is a marine mammal.
It is one of four living species of the order Sirenia, which also includes three species of manatees.
It is the only living representative of the once diverse family Dugongidae; its closest modern relative, Steller’s sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
The bighead carp is a species of freshwater fish, one of several Asian carps. It is one of the most intensively exploited fishes in aquaculture, with an annual worldwide production of over three million tonnes in 2013, principally from China.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

be endangered in the UK, given a Red
Status by the RSPB.
4. 2. SEAGULL
LIFESPAN
Seagulls can live a long life, with reports
of lifespans ranging from 35 – 49 years
old. On top of that, urban gulls tend to live
5% longer than their coastal cousins.
6. 4. HIGH NEST
FIDELITY
The Herring Gull are well known for
having a high nest site fidelity. Once they
have a place to breed they return to it
year after year.
7. 5. SALTY SUPER
POWERS
When seagulls are forced to drink sea
water they have a super power that allows
them to excrete the dangerous salt levels
through glands above their eyes.
8. 6. SHARED

The incubation of seagull chick eggs is
actually shared between the pair of mating
birds. Well done dads!

European seagulls have extremely good
vision in daylight and superior vision to
humans during the night time.

PART 2
New studies have now shown that seagulls
are also capable of seeing ultraviolet light,
another new super power!
11. 9. GULLS ARE
GALLUS
GRIFTERS
Seagulls are omnivore opportunists! They
scavenge on landfill sites, gnaw through
plastic bags and steal the eggs of their fellow
gulls and other species.
12. 10. IRISH
DANCING
SEAGULLS
European seagulls have been observed Irish
dancing! They rhythmically drum their feet on
the ground to vibrate worms and other
sources of food out of the soil. They are
sometimes known as ‘worm charmers’.
