The Herring Song

For all the fish that are in the sea, the herring is the fish for me!  These are the words of a song my mother used to sing, and the whole family would join in the chorus.  But how many fish are in the sea? 

Estimates of the numbers of fish in the oceans vary, of course. How could it be an exact measure? One figure given by scientists places the number of fish in the ocean at 3,500,000,000,000.  That is a lot of fish? 

So, what about 'the fish for me', the herring? Archaeologists counting herring bones  along North America's west coast recently found evidence that herring that had been abundant for thousands of years. 

 Like so many, they are in decline due to overfishing.  Herring collapse has signifcant knock-on effects both for humans and for ecological balance.  Over time, there have been serveral periodic collapses.  Sometimes the recovery has been slow. 

Herring is the fish for me could be a standard for seabirds, With loss of fish such as herring, the seabird population is dramatically affected.  This is certainly so for the Western Grebe that dive for carp, herring, mollusks, crabs, and amphibians, such as salamanders.  But not only does the Western Grebe suffer from loss of a major fish source, it's breeding is also impacted by human activity.  Little wonder then that the population of the Western Grebe is in decline.  

A broader food chain is also detrimentally affected by overfishing.   Killer whales eat seals that eat herring. By blowing bubbles,  Humpback whales confuse the fish before eating them. 

So, is this what the Herring song is about? Not exactly.  The song my mum sang was about the uses we could put herring to.

Prioritising people in nursing care.

There has been in recent years concern that care in the NHS has not been sufficiently 'patient centred', or responsive to the needs of the patient on a case basis. It has been felt in care that it as been the patient who has had to adapt to the regime of care, rather than the other way around. Putting patients at the centre of care means being responsive to their needs and supporting them through the process of health care delivery.  Patients should not become identikit sausages in a production line. The nurses body, the Nursing and Midwifery Council has responded to this challenge with a revised code of practice reflection get changes in health and social care since the previous code was published in 2008. The Code describes the professional standards of practice and behaviour for nurses and midwives. Four themes describe what nurses and midwives are expected to do: prioritise people practise effectively preserve safety, and promote professionalism and trust.

The internet trails of Ants

Ants share, and they are built to do just that.  They walk and talk to cooperate in all they do.  Ants have two stomachs, with the second one set aside for storing food to be shared with other ants.  Ants get pretty intimate when meeting each other.  The ants kiss, but this kiss isn't any ordinary kind of kiss. Instead, they regurgitate food and exchange it with one another.  By sharing saliva and food,  ants communicate.  Each ant colony has a unique smell, so members recognize each other and sniff out intruders. In addition, all ants can produce pheromones, which are scent chemicals used for communication and to make trails. Ants are problem solvers.  We may recall the problems puzzles we were given as children. We look to see if the pieces will fit.  Jiz saw puzzles are much the same but with many contextual factors. First, the picture tells a story. Then, once we know what the image might be, it becomes easier to see which pieces to look for.  Ants lay down trails. Just as we f
