References Abstract The ways in which fires affect biodiversity are considered using examples from the semi-arid mallee, the cold Tablelands of Tasmania, the woodlands of the Australian Capital Territory ACT and coastal heathlands of mainland southeastern Australia. In the mallee, many plant species lie hidden in the soil as propagules - rather than being apparent as mature plants.
Messenger As we age, the smooth skin of childhood gives way to all sorts of mysterious lumps and bumps.
In a high-UV environment like Australia, we need to be very alert to the possibility of skin cancers. But most of the skin lumps we develop will be benign.
Here are some of the most common, and how to tell them apart. Moles Moles, or naeviare the most common skin lesions. They can be brown, black, pink, the same colour as the surrounding skin, or even blue if the melanocytes are clustered deep in the dermal inner layer of the skin.
Most moles are flat but they can also be raised. Banksia case study some people have moles at birth, they usually begin to appear during childhood and keep developing through to your 40s, when they start to slowly disappear again.
The number of moles you have is partly controlled by genetics, but is also influenced by your environment. Lots of sun exposure leads to more moles, and so can using certain medicationssuch as those that suppress your immune system. Many more look like moles in their early stages. If the lesion is asymmetrical, multi-coloured or has other signs of melanoma, the doctor will excise it for further testing.
UQ Having many moles is the strongest predictor of a high melanoma risk, so people with many moles are often advised to have regular skin checks with a dermatologist. For the rest of us, self-examinations are recommended.
As a follow-up to Tuesday’s post about the majority-minority public schools in Oslo, the following brief account reports the latest statistics on the cultural enrichment of schools in Austria. Vienna is the most fully enriched location, and seems to be in roughly the same situation as Oslo.

Abstract Since , evidence has accumulated that suggests boron is a safe and effective treatment for some forms of arthritis. Enlightenment botany was replete with sexual symbolism―to the extent that many botanical textbooks were widely considered pornographic. Carl Linnaeus's controversial new system for classifying plants based on their sexual characteristics, as well as his use of language resonating with erotic allusions, provoked intense public debate over the morality of botanical study.
Seborrhoeic keratoses Seborrhoeic keratosessometimes inelegantly called senile warts or barnacles, are another common benign skin lesion. These are considered part of the normal skin ageing process. These wart-like growths can begin to appear in your 30s and 40s.
They can erupt suddenly after a sunburn or a bout of dermatitis, or gradually appear for no discernible reason. If many itchy seborrhoeic keratoses erupt suddenly, it is occasionally a sign of an internal cancer. Very rarely, basal or squamous cell carcinomas arise within a pre-existing seborrhoeic keratosis.
Seborrhoeic keratoses themselves are harmless, but can be prolific — some people have hundreds — and they increase in number as the years go by. Some people develop lots of seborrhoeic keratoses, both big and small.
Their colour ranges from pale yellow to black. They can be waxy, warty or scaly, and anywhere between 1mm and several centimetres across. Those that are dark and large can look alarming, but when seen under a dermoscope they usually have a characteristic brain-like or banksia-like appearance and are easily distinguished from skin cancers.
If in doubt, your doctor will take a biopsy to investigate further, since a melanoma can occasionally simulate a seborrhoeic keratosis. Seborrhoeic keratoses can be annoying if they snag on clothes or get in the way of your razor, and some people find them unsightly. In these cases they can be removed by freezingcutting them offburning, laser surgery, chemical peels or excision with scalpel or scissors.
UQ Cysts A cyst is a round lesion made of a capsule filled with keratin the structural material that makes up the outer layer of our skinsebum the oil from our skinfluid or pus-like material. Firm or squishy to the touch, they are totally benign.
Sometimes cysts form when injured skin gets tucked in to form a pocket and the maturing and dying skin cells build up inside it. Other cysts are formed when epidermal cellsnormally found on the surface of the skin, proliferate in the deeper dermis and fill up in a similar way.As we age, the smooth skin of childhood gives way to all sorts of mysterious lumps and bumps.
