“Yarp, Yarp, Yarp” – Mother-in-law bird


Some people get a “bee in their bonnet”;

I have a bird on the brain.

 

It’s a bird I first heard while up in the hill farmland over Hawkes Bay, long before I saw it. It has a distinctive call. ‘Yarp, yarp, yarp, yarp…’ I asked one of the local farmers about it. He named it the ‘Mother-In-Law’ bird – really, the Spur-Wing Plover.

The farming community did not approve of it, as it is a ground nesting bird, making its scrape in the centre of an open space. It is also extremely protective of its scrape, at which one partner of the other is always in attendance, if not covering the clutch of eggs.

If any person or farm beast approaches too closely, they will rise and swoop ferociously at the intruder,  screaming, and trying to rake their spurs – complete with poison glands – across any part they can swipe over.

I saw a couple in Palmerston North, in the front grounds of the Research complex. For weeks they strutted around their scrape. Staff there mentioned how the groundkeeper never mowed their real estate, leaving them a wide berth. One Monday morning, there was only one. I learned from a scientist there that they mate for life, and if one is killed, the other will stay around their site for years before giving up. I would see the lone mate on the peak of the roof, and hear it calling to its spouse. I fell in love with the bird, right then.

The next time I saw them was in Masterton, in a new housing area on what had been a football club’s ground. I left the car to move closer to the scrape, over which the pair were already wheeling. And, yes, they swept over towards me. They didn’t rake me – I’d lowered my head, and turned back to the car.

Now in Rotorua, I’ve heard a pair flying over our house during the evening, just around sun down, every autumn.

‘Yarp, yarp, yarp, yarp…’ I love their call. It’s as if one is calling to the other ‘Come on, I’m taking you home’, while the spouse calls back ‘I’m coming, I’m coming’.

20170523_124346I know where they go. I’ve seen their scrape one year, in an open green space between a clothing outlet and a large hotel. The space is so wide, truckers have, in summer, parked their rigs there for the public to see them up close, and rides are given to special children.

20170523_124438Last year, I didn’t see the Plovers – only their abandoned scrape, after a week-end’s ‘paddock bashing’ by hoons spinning across their nesting site that autumn. I only saw the mess of their scrape – two shattered shells, abandoned.

The marks of their tyres are still there now, along with the marks of a go-cart, being ridden by a child under Dad’s supervision, during summer when the plovers would have been back in farmland.

2017-05-23 12.51.44Today I caught some pictures of the couple.
They seem to have chosen a nesting site a little
closer to the hotel, but still with a
clear space for lookout duty all around them.

They may start their family.

That is a freaking CAT prowling around!

They may get through the autumn and winter
without being disturbed, or killed. I hope so.

Cole’s Funny Picture Book 1


Cole was a book dealer in Melbourne, whose “Book Arcade” was the biggest book outlet of its day.

Cole published two Picture Books for children, and one included a section titled Smoking Land (among other sections titles as, for example, Naughty Girls, Boys’ Names, Puppy Land, School Land…).

The Gutenberg Press has converted the Coles Funny Picture Book 1; from this I rediscovered some of the (now, fairly horrendous) rhymes written for children in 1879.

First 2017 prompt :: YEAR


Well, the Daily Prompt folks have delighted me, by not making 1st January’s prompt “Resolutions”. Thanks for the common sense, good folk. It would have been too easy, too over-done, too lazy … for any  to really give a toss about. So … “Year” – ‘A Year Of…’, ‘A Year For…’, ‘A Year In…’, ‘A Year With…’ – endless possibilities here. (You can probably tell I’m desperately thinking as I write this.) What will I wrap ‘Year’ around? Well, regardless of it being too obvious, it’s my view on 2017; plans? promises? problems? (Nah, not problems-let’s keep it positive.) politics? (Nah, not politics-let’s keep it positive. Did someone just say that?)  It’ll definitely be a year of remembrances and anniversaries, some light, some dire…

Amateur Orchid Care–3rd From the Top


In response to The Daily Post’s writing prompt: “Third From the Top.” (March 25th)

In the Reader’s “Blogs I Follow”, from the third post in the list, work the third sentence into your own post.  So I pop to the reader (often forgotten, sorry), and there, third from top, is Avalon-Media. And the third sentence is:
“From creating to storing, the following tools are not essential for making your own herb and spice blends, these tools are not just practical but convenient and useful.”
I am Not a Cook, so this will take some “working”, methinks.

I’m an amateur Orchid lover, and only a few years ago realised for how long I’d been touched by orchids. Firstly at age eighteen in 1970, boarding with a beloved aunt, Edie – a Master jeweller – who had orchids in her garden, and every Monday throughout the year would take a spike of blooms into her store, to create a corsage for every woman brought in by her fiancé to purchase their engagement and later their wedding ring. Now, with an extending collection, I can call myself an Orchid Amateur.

One of the distinctions between an Orchid Amateur and an Orchid Enthusiast: Enthusiasts want to know the whole scientific name, from Genera down to variety. We Amateurs don’t bother–we like the blooms, and don’t really care that the lack of the name won’t win us any prizes.

I joined the Orchid & Bromeliad Society in our new city, and have joined in on trips to visit shows in other towns, nurseries, a native orchid reserve, and attended demonstrations of care practices. I’ve fallen for Bromeliads, especially Bilbergias and Tillandsias.
But I’ve learned Cymbidium orchids are my best success stories in terms of blooming and easy care.

From creating baby orchids (observed and learned only, not practised) to displaying blooms, the following tools are not essential for having success with your orchid as an amateur, but these ‘tools’ are not only practical but convenient and useful.”

  1. The right place. Cymbidiums need coolness in winter when not in flower, so the bulb can be shocked into realising it will have to bloom come late spring. A place on the polar side of the house is best. This is subject to the next point…
  2. The right medium. Cymbidiums can be established in the ground–if you live in a warm climate. Otherwise, a bark or pine chip mix, in pots you can move. (Check the bag for warnings about using a dust mask, please.)
  3. Feed specific to orchids’ needs. My Dad (this horrified our society president) only ever fed his Cyms with the rinsings from an empty milk bottle.
    Commercial products do give you a more balanced feed, but seek advice on how strongly to mix it, and when, how often, and how to apply it – it all depends on the variety.
    Basically, Nitrogen feed leaves, Potash feeds roots, Potassium feeds blooms.

  4. Shelter from summer’s extreme heat. Under the eaves, under a shade-cloth affixed to the fence and draped over a frame work will do. A car-port is perfect. One friend had the local sail maker create a covering shaped to fit her rotary clothesline–it worked, but interfered on laundry day.
  5. Deterrents for bush cockroaches, slaters (known as pill bugs in the US?), earwigs, and other diners on roots, bulbs and flowers. (Copper tape around the top edge of a pot apparently “fritzes” snails and slugs trying to cross it on their way to eat the petals, but it can be expensive.)
  6. A place in the house. When my Cyms start to open their first blooms (late spring to summer), I shift the pots into my bath room. Actually, into the bath tub. Once finished flowering, I move them back outside.
  7. A rubber, raised-edge mat. I use one which was designed for the garage, to collect any leaking car oil. It sits inside the bath tub, and prevents staining from the bark colouring when watering the plants. In the bathroom (which has plenty of natural light) I can check them every day, they are not too hot in summer, and I can select one to put on display.
  8. Old wire coat hangers and wire cutters. (Huh?) Use these to form pieces of the coat hanger into sticks with a curved hook on one end, to be rammed into the pot beside a new flower spike to force it to grow upwards. Sideways growing spikes get too heavy to support the weight of their blooms, which end up dropping down to the soil and become ragged. (It’s possible to buy these ready made, btw.)
  9. Secateurs – and a sterilising liquid. Use these to clip dead flower spikes ‘way down at their base. Don’t try pulling them out, as they’re likely to tear the plant apart, or out of the soil. Sterilise the secateurs between plants – avoid spreading disease.
  10. Spare pots. Recycle old ones, by all means–but sterilise them.
  11. A hooked garden hand-fork. When the time comes to lift a potted orchid to either repot for health or to divide and repot when crowded, this makes it much easier to gently separated the tangled roots from clinging bits of old potting mix.
  12. A piece of broom handle. Use this to tamp down the newly potted plant’s medium to secure it firmly.
  13. A camera. What’s the point of working hard to help your Cymbidiums to flower well if you can’t brag about it?

Foetal Damage caused by Marijuana?


Foetal Damage caused by Marijuana?
A gleaning of extracts from various sources, all credited.

All extracts retrieved on 8th October 2014.
This is a personally biased selection of articles. I will not apologise for my bias. If my bias disturbs or annoys you, then move on to another blog.
I am aware there are both many more articles, and many more scientific articles out there, just as there are many article proposing there is no harm at all to a developing foetus from parents’, especially mothers’, use of marijuana or THC in any of its forms before conception, during pregnancy or after birth while breastfeeding.
I do not subscribe to the concept of marijuana use not harming an unborn child – I have had too many children of marijuana-using parents in my classrooms, seen their poor cognitive abilities, poor assessment results, poor attention spans, inability to develop abstract thinking. Such children are just as difficult to educate as children with FAS.
New Zealand’s “Green Party” lost my political interest when I learned they support legalisation of marijuana.

From :: Why Cannabis Must Remain Illegal
http://www.drugwatch.org/resources/publications/articles/195-why-cannabis-must-remain-illegal.html
WHAT IS CANNABIS?
This so-called soft drug is a toxic narcotic (UN 1961 Single Convention Amended in 1972).

It has no medical benefits (see http://www.eurad.com…Research).
A single joint is composed of more than 400 different chemicals, all of them toxic.
On combustion these multiply into about 2,000 equally poisonous chemicals.
Cannabis is different from alcohol, heroin or other drugs because it is fat-soluble.
This causes it to be absorbed into the brain and other fatty organs of the body where it is stored for months in both the chronic and so-called recreational user, resulting in the person becoming stupefied.
It is only very slowly released from the body, which explains the absence of severe withdrawals.
This lulls the person into believing that he or she is not addicted.
While in the body the toxins are attacking every cell, system, and organ present, with the brain sustaining the most damage, as it is one-third fat.

The chemicals in cannabis adversely affect the central nervous system, cardiovascular, respiratory, and immune systems.
Foetal damage is incurred in pregnant women, and a rare form of leukemia can be caused in infants.
Cannabis is a highly carcinogenic drug.
American studies have shown cellular damage to the lungs of cannabis smokers, who smoke two joints of cannabis a day, to be as harmful as the damage caused by 28 tobacco cigarettes.
APOPTOSIS
Decreases in sperm production and increases in abnormal forms caused by THC have been recently attributed to a biological phenomenon known as “apoptosis” of the cell.
Apoptosis is the process of programmed cell death occurring over hours and days, in successive stages, resulting in the fragmentation of DNA and the disintegration of the cell.
It is a fundamental process emphasized in the first report on the human genome (2001).
Apoptosis is controlled by an important cluster (home box) of genes, which order the self-destruction, or suicide of the cell. (Nahas)
An incorrect assumption of some scientists was that recreational usage of cannabis would not produce apoptosis.
They failed to take into account the distribution of THC throughout the body and it’s lengthy storage in fat depots and subsequent slow release in the same active form as when first ingested.

After a single cannabis cigarette, 50% of its THC is stored in fat depots for five days. It will take 30 days for its complete elimination. If one smokes one joint every two days, one will store ten times more than the initial dose of THC after ten days and 30 times more after 30 days. Such amounts have been scientifically proven to induce apoptosis of sperm cells and of lymphocytes. (Nahas)

The fat-soluble smoke in cannabis damages the brain, respiratory tract, immune system and the unborn foetus.
Users cause damage to society through family breakdown, road accidents, and violent acts.

From :: Cannabis: Good For Pain, but bad for your health?
Dr Thomas Stuttaford, The Times, 24th October 2005
http://www.thehempire.com/index.php/cannabis/news/4569

Cannabis has an adverse effect on the reproductive system in men and women.
In women it may cause ovulatory and menstrual irregularities, and in men can cause testicular atrophy with a marked reduction in sperm count.
The babies born to cannabis-smoking couples are, on average, shorter, have a lower birth weight and reduced head circumference, and after delivery are more restless and nervous.
As children they have an appreciably higher incidence of one form of leukaemia, have poorer memories and verbal ability as toddlers, and do less well in intelligence tests up to the age of 9.
In rodents there is an increased incidence of foetal abnormalities and stillbirths in those given cannabis.
Similarly, a long-term project evaluating the effect of cannabis on rhesus monkeys, either before or during pregnancy, showed that it quadrupled the death rate of babies in utero or soon after birth. There was also a higher incidence of congenital neurological deformities.
Although there have been reports of similar findings in humans, a relationship between cannabis and foetal abnormality is difficult to prove.

Pregnancy
Using cannabis products may have a harmful effect on foetal growth.
Tetrahydrocannabinol (THC) passes through the placental barrier, causing higher carbon monoxide levels in blood circulation than smoking.
Study results indicate that foetal exposure to cannabis products may cause permanent changes in the function of the developing central nervous system.
Breastfeeding
THC, the active ingredient in hashish and marijuana, accumulates in breast milk.
The accumulated levels found in breast milk can be 10-fold to concentrations detected in maternal circulation. Regular exposure to THC can have a harmful effect on the development of the child’s central nervous system, and therefore mothers using cannabis products should never breastfeed their babies.

From :: Smoking Cannabis During Pregnancy Could Affect Foetal Brain Function
by Karthika on June 18, 2008 at 5:37 PM, Women Health News
http://www.medindia.net/news/smoking-cannabis-during-pregnancy-could-affect-foetal-brain-function-38164-1.htm

Women who smoke cannabis during pregnancy may be putting their developing foetus in danger, revealed an experimental study involving mice.
The study conducted by the research team at the University of Aberdeen also stressed that some of the prescribed drugs, including some to treat obesity, could also have detrimental effects in the womb.
Focusing on the importance of molecules produced naturally in the brain and how certain nerve cells recognise and connect with each other, the research claimed that anything that disrupts this process, like cannabis smoking, could affect brain function.
The researchers said that the brain molecules called endocannabinoids behave in the same way as tetrahydrocannabinol (THC) from cannabis, and affect the same receptors and signalling systems in the brain.
However, they stressed that this signalling process should occur unhindered, so that the brain can develop normally.
“Our findings highlight that the integrity of this signalling system should be maintained and not disrupted if the brain is to develop normally,” BBc quoted Prof Tibor Harkany, recruited to the University of Aberdeen as part of the Scottish Universities Life Sciences Alliance (Sulsa), as saying.
He added: “Anything that disrupts this process such as cannabis smoking or certain drugs that interfere with this signalling system could ultimately affect the brain’s functionality.”
“Our initial findings showed the importance of these naturally occurring molecules in guiding the growth and connections of nerve cells in the developing brain,” said Jan Mulder, first author of the study and Alzheimer’s Research Trust fellow at the University of Aberdeen’s Institute of Medical Sciences.
He added: “Now we demonstrate the extent of this signalling system and that complex network of neurons – the backbones of higher cognitive functions – do not develop normally when endocannabinoid signalling is disturbed.”
Cannabis is considered to be one of the most widely used drugs by women at reproductive age, and earlier studies have pointed out that babies born to mothers who took cannabis while they were pregnant, experienced problems with physical activity.
The new study is published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS)

http://cannabisvictim.blogspot.co.nz/

In a letter published in NZ Herald 4 June 1997 Dr K.M. Ewen, MB ChB, FRCS, FRACS (retd), stated:
Cannabis indifference
I am amazed and dismayed by the superficial debate by our politicians about cannabis.
Successive Ministers of Health and of Social Welfare have failed to address this problem adequately.
Cannabis is a fat-soluble drug which lodges in all tissues, especially the brain.
It has a “half life” of about 7 days and therefore anyone who smokes it at least weekly has a steadily rising blood level.
It has all the bad properties of alcohol excess and thus [properties of] the “foetal alcohol syndrome” as it crosses the placenta readily.
Brain damage occurs in the foetus more severely than in adults and affects the higher centers involving conscience, moral behaviour, short-term memory and later long-term memory.

From :: Marijuana: Prenatal and Postnatal Exposure in the Human
Katherine Tennes, M.A., Nanci Avitable, M.A., Carol Blackard, M.D., Cecilia Boyles, M.A., Bernice Hassoun, B.S., Larry Holmes, M.S., and Marie Kreye, Ph.D.
http://archives.drugabuse.gov/pdf/monographs/monograph59/048-060_Tennes.pdf

Recent studies of prenatal exposure to marijuana have produced presumptive evidence that marijuana has an adverse effect on growth and development of the fetus.
Two investigators (Linn et al. 1983; Gibson et al. 1983) reported a decrease in birth weight and an increase in malformations in marijuana-exposed infants, but differences between marijuana users and nonusers were not statistically significant when confounding factors were taken into account.
Hingson et al. (1982) reported that woman who used marijuana during pregnancy delivered infants with a mean birth weight 105 grams lighter than infants of nonusers, and the infants were five times mere likely than infants of nonusers to have features compatible with Fetal Alcohol Syndrome.

Infant Outcomes
Heavy marijuana use was found to be associated with an increase in male over female offspring, a finding previously reported by Fried (1982).
Women who reported smoking marijuana three times a week or more throughout pregnancy (N = 31) gave birth to 61% males and 38% females as compared with 50% males and 49% females among nonusers (N = 498). Among fathers who were reported to be chronic smokers of more than one ‘joint” a day, the ratio was 67% males to 33% females (table 3).
Intrauterine Growth
Multivariate analyses of the impact of marijuana on three measures of fetal growth—birth weight, length aid head circumference—did not yield uniform results.
Infant length was the only measure influenced by marijuana when confounding variables were taken into account.
Of eight variables, accounting for 22% of the variance in length, marijuana (total amount used during the first trimester) entered the regression on the fourth step (table 4).
Other confounding variables considered in the regression that did not reach significance were: mother’s age, parity, Hispanic race, socioeconomic status, caffeine, alcohol, hash, amphetamines, aid cocaine.
As calculated from the unstandardized p-coefficients, the reduction of .55 centimetres in length, attributable to
smoking an average of three joints a day during the first trimester, was roughly comparable to the reduction of .48 centimetres attributable to smoking one-and-a-half packs per day of cigarettes
Postnatal Outcomes
Of 39 infants with major malformations recorded in the infants’ medical records, 12 (31%) were children of marijuana users...
Discussion
The findings in this investigation are consistent with other studies that have reported a trend toward or a significant reduction in fetal growth associated with exposure to marijuana during gestation (Hingson et al. 1982: Linn et al. 1983; Gibson et al. 1983).

From :: Marijuana Impacts Fetal Brain Development During Pregnancy
Thomas Carranante
http://www.scienceworldreport.com/articles/12454/20140127/marijuana-impacts-fetal-brain-development-during-pregnancy.htm

Despite making favorable headlines throughout the United States following legalization in Washington and Colorado, marijuana is still regarded as a direct cause for the endangerment of fetal brain development.
Professor of Developmental Neurobiology, Tibor Harkany of the Karolinska Institutet in Sweden, published his findings in this month’s issue of the EMBO Journal.
He stated that the consumption of cannabis during pregnancy directly affects the development of nerve cells of the cerebral cortex, the part of the brain that orchestrates higher cognitive functions and drives memory formation.
In the study, cannabis (scientifically known as “delta-9-tetrahydrocannabinol” or “THC”) was tested on mice and human brain tissue in order to see how it affected an unborn fetus. Specifically, the scientists found that THC negatively impacted the operation of the structural platform between nerve cells. This primarily involves how the nerve cells will develop and function.
If the nerve cells don’t fully develop, then they will not connect properly–if at all.
“Even if THC only would cause small changes, its effect may well be sufficient to sensitize the brain to later stressors or diseases to provoke neuropsychiatric illnesses in those affected in the future,” says Professor Harkany in this EurekAlert! article. “This concerns also the medical use of Cannabis, which should be avoided during pregnancy.”
In addition to Professor Harkany’s researchers in Sweden and Austria, researchers from the United States, Germany, Finland, and the United Kingdom participated thanks to funded grants from the Scottish Universities Life Science Alliance, the Swedish Research Council, Hjarnfonden, the Novo Nordisk Foundation, the Welcome Trust, and the National Institutes of Health.
The researchers arrived at the conclusion that “these developmental deficits may evoke life-long modifications to the brain function of those affected” (found in the same article *) and [marijuana] should be avoided altogether during pregnancy.

* From :: Cannabis during pregnancy endangers fetal brain development
http://www.eurekalert.org/pub_releases/2014-01/ki-cdp012314.php

An increasing number of children suffer from the consequences of maternal drug exposure during pregnancy, and Cannabis is one of the most frequently used substances.
This motivated the study, published in the EMBO Journal, cunducted in mice and human brain tissue, to decipher the molecular basis of how the major psychoactive component from Cannabis called delta-9-tetrahydrocannabinol or THC affects brain development of the unborn foetus.
The study highlights that consuming Cannabis during pregnancy clearly results in defective development of nerve cells of the cerebral cortex, the part of the brain that orchestrates higher cognitive functions and drives memory formation.
In particular, THC negatively impacts if and how the structural platform and conduit for communication between nerve cells, the synapses and axons, will develop and function.
Researchers also identified Stathmin-2 as a key protein target for THC action, and its loss is characterized as a reason for erroneous nerve growth. It is stressed that Cannabis exposure in experimental models precisely coincided with the fetal period when nerve cells form connections amongst each other.
According to study leader Professor Tibor Harkany, who shares his time between Karolinska Institutet and the Medical University Vienna in Austria, these developmental deficits may evoke life-long modifications to the brain function of those affected.
Even though not all children who have been exposed to Cannabis will suffer immediate and obvious deficits, Professor Harkany warns that relatively subtle damage can significantly increase the risk of delayed neuropsychiatric diseases.
“Even if THC only would cause small changes its effect may well be sufficient to sensitize the brain to later stressors or diseases to provoke neuropsychiatric illnesses in those affected in the future”, says Professor Harkany.
“This concerns also the medical use of Cannabis, which should be avoided during pregnancy

Damned Scarey Seeing This…


When hospitalized with a neurological condition diagnosed as Stiff Person’s Syndrome, I would often go into a spasmic shut down. Often these would lead to me passing out completely, lying unconscious for – must ask hubby as I wasn’t timing myself, that’s for sure.

Quite a few times, I was told, I was “out” and so unresponsive nurses expected me to die. I was warned that without supervision at home I could die after passin unconscious.

I think it may have been during those near final “outages” that I saw these two “screens” – just like the old 8-bit computer screens of the early 80s, and the final dot of light when black-n-white teles were switched off.

Termination 1

… then …

Termination 2

… and … The pin-point of light goes out.

This was me,  passing out.

wonder if it will also be me, dying.

What can we expect, do you think?
