Dragon Flies so colourful

Wildlife This year at Harbour-front Trail, Cootes Paradise and the great lakes are few and far between.The lack of snow-pack , Spring rains has left the water level three feet less than last year, therefore less wildlife and fewer Images. Last year there was over 12 Signets born in Hamilton Harbour, this year due to the City of Hamilton oiling swan eggs and Canadian geese eggs there was only one signet born, all because they say the swans are causing e-Coli Bacteria and making it dangerous for people to swim in the water. I am against the oiling of eggs because the swans sit on the eggs for three Months without any offspring. People complain to the city that there is too much Canadian geese  droppings where they walk. The wildlife was here before us, please leave Mother Nature alone, Humans think they can control everything they come in contact with. Now look at the world we live in, nothing for children too be amazed and nothing to learn, It is like a Silent Spring-Shame- Shame

Readers at pics4twitts send me images quite often, Lois McNaught also walks the Harbour-front trail  Daily and has the same observations as most regulars, “where have all the wildlife gone?”

eight eggs and only one signet-city oils eggs Hamilton.

Dragon fly

Dragonflies

Usually living near water, the dragonfly is one of earth’s creatures that are not only very useful, but also beautiful. They belong to thee insect group Odonata. Dragonflies come in varied colors; their bodies often blue, green, purple, and even bronze. Their wings seem to shimmer as if made of silver, especially when under the moonlight.

Dragon Fly

 Starting out life as small nymphs underwater, they grow to be approximately three inches long, with a wingspan averaging two to five inches in width. While this may seem large for an insect, keep in mind that as they have evolved from pre-historic times, they have gotten considerably smaller. Evidence shows that at one point in time they may have had a wingspan of over two “˜feet’! One very interesting fact of the dragonfly is his six legs. Each of the legs is covered in short bristles. Using their bristle-covered legs to form an oval shaped basket allows them to scoop insects, such as mosquitoes, right out of the air. Dragonflies not only eat mosquitoes; they also keep the fly population and other flying insects under control.

The Bee and the Butterfly

Surprisingly, dragonflies will spend only a very short part of their life span as actual dragonflies. They will live as nymphs for up to four years, shedding their skin up to fifteen times, yet when they finally mature into adults, the dragonfly stage, they will survive only a few months.

Dragonflies have fascinated modern man for years. They have become the basis of both legends and old wives tales. One such old wives tale refers to a dragonfly as a “˜darning needle’. An old legend tells of people who would wake up after falling asleep outside to find their ears and eyes sewn shut by these crafty insects. If dragonflies were seen swarming over a doorway, it was said to foretell of heavy rains on the way.

For as long as man and dragonflies have coexisted, people have mistaken dragonflies for fairies. “˜Fairy tales’ have been told of little people fluttering about worldwide. Upon closer inspection, the fairies are found to be groups of dragonflies.

How many eyes does a dragonfly have?

How many eyes does a dragonfly have? They have two main eyes, but each of these eyes are made up of approximately 20,000 to 25,000 tinier eyes, allowing them to zero in on the flying insects that are their daily meals.

Cootes Paradise

One fine morning, girl, I’ll wake up
Wipe the sleep from my eyes
Go outside and feel the sunshine
Then I know I’ll realize
That as long as you love me, girl, we’ll fly

Hamilton Harbour June

 

And on that mornin’ when I wake up
I’ll see your face inside a cloud
See your smile inside a window
Hear your voice inside a crowd
Calling, “Come with me baby and we’ll fly”

Life abounds

 

And on that mornin’ when I wake up
We’ll go outside and live our dreams
I’ll buy you candies made of stardust
And little dolls dressed up in moonbeams
And everywhere we go we’ll laugh and sing
I’ll kiss you morning, noon and night
And all the universe will smile on us
‘Cause they know that our love is finally right

small obstacles

Yeah, we’ll fly to the east, we’ll fly to the west
There’ll be no place we can’t call our own
Yeah, we’ll fly to the north, we’ll fly to the south
Every planet will become our home

Construction of a Replica Baltimore Clipper

The classified advertisement, placed by the City in the Baltimore Sun on September 24, 1975, seeking proposals to design and construct the first Baltimore Clipper to be built in 150 years, stated that the ship was to be “an authentic example of an historic Baltimore Clipper. The ship is to be between 85′ and 90′ on deck, fully operable, capable of being sailed, and equipped with replica cannon. Construction materials, methods, tools, and procedures are to be typical of the period.” In a word, the ship was to be a replica, built by hand with traditional materials and methods as far as practicable.

Pride of Baltimore

The design/construction contract was awarded to the International Historical Watercraft Society, a corporate designation of master shipwright Melbourne Smith of Annapolis. Smith had extensive experience with traditional ship repair and construction and was an ideal candidate for the task. Design of the vessel was the responsibility of noted naval architect, Thomas Gillmer, long-time professor of naval architecture and engineering at the US Naval Academy in Annapolis.

Crew hard at work

 

The vessel was built during 1976-77 in the open-air Clipper Shipyard on the west shore of the Inner Harbor adjacent to the Maryland Science Center. Work proceeded seven days a week and was followed closely by thousands of Baltimoreans and visitors who watched with fascination as the ship emerged from her keel in the makeshift yard.

Getting ready to cast-off too Montreal

 

Most of the work was done by hand using traditional methods and tools – the adz, the caulker’s hammer, a ship’s saw. Some of the experienced shipwrights were from Central America, associates of Melbourne Smith in a Belize shipyard where they had built and repaired boats for the Caribbean trade. Others were experienced sailors and hands from Maryland who wanted to share in this once-in-a-lifetime opportunity of building an “old style” ship in the traditional way. A master blacksmith, or rather a shipsmith, set up shop on site and forged thousands of special fittings for the vessel. By the time of launch, just ten months after the keel was laid, fifteen devoted craftspeople made up the building crew.

Pride of Baltimore 2

 

 

Pride of Baltimore was launched on February 27, 1977 by “Big Red,” a huge floating crane from the Bethlehem Shipyard that lifted the bare hull like a toy and gently placed her in the water. The traditional bottle of champagne was cracked against her hull by then Congresswoman (now Senator) Barbara Mikulski. But much work remained to be done. Forty tons of fixed ballast were packed along the keel below deck. Ballast consisted of specially molded iron pigs and cubes, as well as ten tons of traditional Belgian paving stones that had been part of Baltimore streets – and had probably arrived from Europe as ballast in 19th century sailing vessels! The two masts and spars of Douglas fir from Oregon were shaped and stepped, and the rigging put in place.

Unrolling sails 1

A major compromise with authenticity occurred late in the ship’s construction process as a result of the incredible excitement stirred by the arrival and visit of six “tall ships” from around the world to the Inner Harbor during the City’s 1976 July 4th Bicentennial Celebration. Sensing that Pride of Baltimore could awaken the same kind of excitement in other ports, City Council authorized an additional $50,000 for a diesel engine for Pride of Baltimore to enable her to travel to distant places and maneuver in crowded ports. Hence, an 85 horsepower Caterpillar propulsion system was sandwiched into the vessel after launch.

On May 1, 1977, Pride of Baltimore was commissioned by Mayor Schaefer in the name of the citizens of Baltimore and Maryland, most of whom, it seemed, were dockside participating in the ceremony.

Her topside was painted black with green anti-fouling paint below the waterline. Her unmistakable signature was a result of her steeply raked masts (17 degrees), the broad white stripe along the exterior gunwale, and her flowing white banner atop the mainmast. With her gaff rigged fore and mainsails set and her square foretop sail raised, Pride of Baltimore was a beautiful and unforgettable reminder of Baltimore’s proud maritime heritage.

Goodwill Ambassador to the World

Women in there environment

During her nine years at sea, between her maiden voyage to Bermuda, New York, and Nova Scotia in 1979 to her final European voyage in 1986, Pride of Baltimore extended the hand of friendship to countless visitors. She visited ports along the Eastern Seaboard from Newfoundland to the Florida Keys, the Great Lakes, the Caribbean Sea and the Gulf of Mexico, and the West Coast of America as far north as British Columbia. On her final voyage, she visited European ports in the Irish Sea, the North Sea, the Baltic Sea, the English Channel, and the Mediterranean – the first Baltimore Clipper to be seen in those waters in 150 years. Altogether, she logged over 150,000 miles, equal to six times around the globe. She sailed further in nine years than most sailing vessels travel in their lifetimes. No museum ship was Pride, but a true Ambassador for Baltimore and Maryland.

A City is Stunned by the Loss of her Pride

On the morning of May 19, 1986, the early morning quiet of the McGeady family home in Severna Park was shattered by the insistent ringing of the telephone. The caller was Joe McGeady who reported that he was calling from the deck of the Norwegian tanker TORO approximately 250 north of Puerto Rico. Pride of Baltimore had been struck and sunk by a violent squall (what the US Coast Guard later called a microburst squall) some four days earlier. The captain and three crew members were missing and presumed dead.

The word spread quickly – to the staff and Board of Pride of Baltimore, Inc., to the families of survivors and those lost at sea, to the news media. In the following days as reports came out, the residents of the City and State watched and prayed with stunned disbelief as the details became known. During a dramatic news conference with the recently rescued survivors at Glen L. Martin Airport a few days later, it was confirmed that Pride of Baltimore had sunk on May 14, having capsized in 80 mile per hour winds that developed suddenly and with no warning. The vessel had been struck and sunk so quickly that there had been no time to radio for help. Eight crew members climbed into a five by five foot rubber life raft where they floated helpless for four days and seven hours with little food or water. The captain and three crew members did not emerge from the wreckage and were presumed lost. Although the survivors saw six vessels during their ordeal, only the TORO spotted them. That was at night – the ship saw an SOS signaled with a flashlight.

Those lost were:

Armin Elsaesser, 42, Captain
Vincent Lazarro, 27, Engineer
Barry Duckworth, 29, Carpenter
Nina Schack, 23, Seaman

The tragedy brought an abrupt end to the adventures of a noble sailing vessel – but not an end to her mission. As the minister at a memorial service for the drowned crew members reminded his audience, “Those who go down to the sea in ships feel particularly close not only to nature, but to God.”

A permanent memorial to the original Pride of Baltimore has been erected in the Inner Harbor on Rash Field. The memorial consists of the characteristic raked mast of a Baltimore Clipper along with the names of those lost in the tragedy carved into pink granite. The memorial reminds those who visit it of the precariousness of life at sea, a lesson the citizens of this great port city once knew well but had long forgotten.

Genetic Diversity of Mute Swans and Egg Clutch Size

TUESDAY MARCH 1 2011

Busking

 

Researcher Anne Charmontier, from England, has devoted most of her professional career investigating Genetic Diversity of Mute Swans as a wild and avian bird population. Along with other researchers Charmontier published in American Naturalist a 25-year study regarding Egg Clutch Size entitled “Mute Swan Population Helps Explain Evolutionary Question.” In this study the scientific question was – Why does a population’s average clutch size differ from the most productive clutch size ? Charmontier and the other researchers hypothesis was supported in this study results that (a) recent relaxation on food constraints, and, (b) an increase of protection from predators, both may have helped the Mute Swans to Evolve towards a Larger Clutch Size. In her work, Charmontier has studied and published data on (1) Evolutionary response to egg clutch size, (2) Individual variation in rates of Senescence: Natal Origin Effects in wild bird populations, (3) Seasonal Changes in Male/Female Mute Swans, (4) Climate Changes in wild bird population; (5) Genetic Models of Mate Choice in the wild; (6) Variations in Breeding Behaviour; and, her current work in 2,011 is entitled (7) “Age-Dependent Genetic Variations in the Life-History Traits of Mute Swans.” Other researchers measured the eggs and hatching mass in birds and reptiles. They found in birds the most important factor affecting hatching mass (HM) was the initial egg mass (IEM) at laying the egg. They also found a physiological link between (IEM) and (HM) which contrast the observed relationship between egg mass and the incubation period. The results of this study, for birds and reptiles, showed “significant implications for the interrelationships between (IEM) and Embryonic Growth (of the Cygnet within the egg in swans).” Another study of 1,525 bird species and 201 reptile species investigated initial egg mass (IEM) and incubation period (IP). Their statistical ANOVA tables demonstrated that for bird eggs incubation period is NOT determined in large part by egg mass. And this study’s results allowed for new scientific questions to be proved by researchers. Two of these questions include (1) Ecological and Physiological Factors affecting the Length of Incubation Period, and, (2) The Rates of Embryonic Growth for different taxa (animal kingdoms) and habitats. In light of these studies considering Embryonic Growth within the Mute Swan’s egg, how do you feel about some people spraying the eggs with corn oil so they won’t grow and the pen Mute Swan would sit on those eggs forever with no cygnets hatching ?

Heterozygosis is dissimilar pairs of Genes or in a Cell the loss of normal function of one allele (different forms) of a Gene. Genetic variations from Genes are important in zoology and nature in general ! In Mute Swans and other animals body proportions can change depending where particular master Hox Genes are active. The same Hox Gene – Hox C6 – switches on at different points along the body. The Hox Gene marks the beginning of the Thorax, therefore, different species end up with necks of varying lengths…a long neck in the goose…and a much longer neck in Mute Swans, according to National Geographic’s “Fins to Wings.” In the Journal of Zoology March 2,011 issue includes a study on “Genetic Diversity in Birds associated with (1) Body Mass (BM), and (2) Habitat Type (HT) [aquatic or terrestrial] in 76 Avian Bird Species.” These variables were chosen because (BM) and (HT) are predictors of Genetic Variation which is very similar in birds. The results of this study show Terrestrial birds have a greater Genetic Diversity than Aquatic species. And, these results were interpreted from published data of other vertebrates that suggest the “Patterns of Genetic Diversity in Birds” depends on two relationships, namely (1) Bird Evolutionary effective POPULATION SIZE , determined in part by Ecological and Environmental features, and, (2) on the Rate of Molecular Evolution. J. L. Quinn stated in the Journal of Evolutionary Biology that “Evolutionary Biologists increasingly use pedigree-based quantitative Genetic Methods to address questions about the Evolutionary Dynamics of Traits in wild bird populations: data depth (number of years) and completeness (number of observations). The results of J.L. Quinn’s study showed by using long-term studies of the Great Tit and Mute Swan Estimated Breeding Values in the Great Tit were NOT influenced by data depth; but, Breeding Values WERE INFLUENCED by data depth (number of years) in the Mute Swans. This influence in Breeding Values by Data Depth was probably due to the differences in pedigree structure between the Mute Swan and Great Tit. At Chicago’s Field Museum of Natural History, Sushma Reddy published in Science “Genetic Sequence of 169 Birds.” In the study results Reddy indicated “Flamingoes and some other aquatic birds did not evolve from water birds, instead, they adapted to life on the water.” Along the same line of thinking, Evolution Diary states “New bird family tree reveals same odd ducks.” The Mute Swan (Cygrus olor) is a species of swan, and thus a member of the duck, goose and swan family Anatidae. E. Marjorie Northcote, Cambridge University, England study indicated “Limb bones of Mute Swans from Neolithic [the last part of the Stone Age - not a time frame, but state of the culture] to the Bronze Age in Cambridgeshire PEAT were larger than that of a recent sample when compared biometrically.” That means, a study of biological phenomena, such as, measuring physical characteristics, such as, Limb Bones of Mute Swans.

Mute Swans 6,000 years old are found in post-glacial PEAT beds at East Anglia in England. Despite the Eurasian origin of Mute Swans, its closest relatives are the Black Swan of Australia and the Black-Necked Swan of South America. The Mute Swan is constantly criticized for stealing Trumpeter Swan, native to Canada, nesting sites. Conversely, in a List Of Animals Displaying Homosexual Behaviour it included Black Swans. This listing stated: “The Black Swan (Cygnus Atratus) is a large waterbird that breeds mainly in the southeast and southwest regions of Australia. An estimated 1/4 of all Black Swan pairings are homosexual and they STEAL NESTS, or form temporary threesomes with females to obtain eggs, driving away the female after she lays the egg.” The Stealing of Nests seems to be a family trait in both Mute and Black Swans. . For many years Black Swans have been on the River Thames in Stratford, Ontario and there were a pair at White Chapel Pond in Hamilton, Ontario. The International Union For Conservation Of Nature (IUCN) founded in 1963, Red |List or Threatened Species is the world’s most comprehensive inventory of the global conservation status of plant and animal species. The (IUCN) is also the world’s main authority on the conservation status of species. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. Joseph Travis, Presidential Address of the American Society of Naturalists stated: “Ecology and Evolutionary Biology are fundamental processes that unfold from a variety of histories. The task of our science is to match the question to organisms, or systems. For many scientist, the organism leads to the question when we observe (participant observation) some of nature’s striking phenomena.”
