  1. NOT so harmless...

    Excerpt: "Introducing #KareniaMikimotoi

    "The species responsible for recent events in #SouthAustralia beaches, #KMikimotoi, causes harmful #algal blooms in #Asia, #Europe, #SouthAfrica and #SouthAmerica, as well as #Australia and #NewZealand. These blooms all caused fish deaths, and some also caused #breathing difficulties among local #beachgoers.

    "The most drastic of these K. mikimotoi blooms have occurred in China over the past two decades. In 2012, more than 300 square kilometres of abalone farms were affected, causing about A$525 million in lost production.

    Explaining the toxic effects

    "Microalgae can damage the gills of fish and shellfish, preventing them from breathing. This is the main cause of death. But some studies have also found damage to the gastrointestinal tracts and livers of fish.

    "Tests using fish gill cells clearly show the dramatic toxic effect of K. mikimotoi. When the fish gill cells were exposed to intact K. mikimotoi cells, after 3.5 hours more than 80% of the fish cells had died.

    "Fortunately, the toxin does not persist in the environment after the K. mikimotoi cells are dead. So once the bloom is over, the marine environment can recover relatively quickly.

    "Its toxicity is partly due to the algae’s production of 'reactive oxygen species', reactive forms of oxygen molecules which can cause the deaths of cells in high doses. K. mikimotoi cells may also produce lipid (fat) molecules that cause some toxic effects.

    "Finally, a very dense bloom of microalgae can sometimes reduce the amount of dissolved oxygen in the water column, which means there is less oxygen for other marine life.

    "The human health effects are not very well known but probably relate to the reactive oxygen species being an irritant.

    "K. mikimitoi cells can also produce 'mucilage', a type of thick, gluey substance made of complex sugars, which can accumulate #bacteria inside it. This can cause 'sea foam', which was evident on beaches last week.

    "A question for many people is whether increasing water temperatures make blooms of K. mikimotoi more likely.

    "Another concern is whether nutrient runoff from farms, cities and #aquaculture could cause more harmful algal blooms.

    "Unfortunately, for Australia at least, the answer to these questions is we don’t know yet. While we know some harmful algal blooms do increase when nutrient runoff is higher, others actually prefer fewer nutrients or colder temperatures.

    "We do know warmer water species seem to be moving further south along the Australian coastline, changing #phytoplankton species abundance and distribution.

    "While some microalgal blooms can cause bioluminescence that is beautiful to watch, others such as K. mikimotoi can cause skin and respiratory irritations.

    If you notice discoloured water, fish deaths or excessive sea foam along the coast or in an estuary, avoid fishing or swimming in the area and notify local primary industry or environmental authorities in your state."

  11. Here is your lunchtime read - my latest for #LWOS. #Habs rookie camp opens tomorrow and here are the storylines to watch.

  12. Idyllic rural NSW is a hotspot for motor neurone disease

    "Our recent mortality paper shows that if you live in rural and regional Australia, you are 40 per cent more likely to die from motor neurone disease. This cannot be genetic."
    "Much attention will be focused on MND hotspots which include regional centres such as Griffith, Leeton, Wagga Wagga and Narrandera in the Riverina where rates of the degenerative illness are estimated to be five to seven times the national average. Other areas of concern include Tamworth, Coffs Harbour and Port Macquarie." >>

  13. 🏒🥅 “Fire us up, Marty!”

    This was a fun club to watch last year. This year, I don’t count them out as serious trouble for any club competing for the Cup. That includes my Oilers. It definitely includes the Panthers (Marty and the Habs had their number during the regular season last year.)

  14. So, the waters off the Maine coast have been warming up (it was very warm when I last waded in the waters in May). Seems
    Karenia mikimotoi has appeared here as well. I expect to see it return with warming waters... Also, this article claims it's less toxic that Red Tide (a cousin) -- but from what I just read in the ABC News article, I would disagree with that! @anne_twain @Tooden

    From WHOI:

    "Karenia mikimotoi

    - Globally distributed, can cause mass die-offs of shellfish, crustaceans, echinoderms and fish
    - Karenia mikimotoi produces several toxic compounds, blooms can also lead to anoxic conditions
    - First bloom in Maine occurred in 2017, with a second bloom in 2019
    - Karenia mikimotoi is also found in Massachusetts waters

    "What is Karenia mikimotoi?

    "In recent years, the genus Karenia has made the news in the United States as a result of the massive #RedTides caused by #KareniaBrevis [That's the one I know about]. These blooms have caused widespread fish and wildlife mortalities and impacted public health in Florida leading to significantly disrupted tourism and fisheries industries which have cost local economies millions of dollars in damages on an almost annual basis.

    "Compared to this notorious HAB species, its sister species, Karenia mikimotoi, is less toxic [!!! Ummmm....] but more globally widespread with blooms reported in Ireland, Norway, India, Japan, Korea Australia, South Africa, Alaska, Texas, and the east coast of the U.S. The blooms of this species can stretch many kilometers, persist for multiple months, and reach concentrations of several million algal cells per liter.

    "There have not been confirmed reports of direct impacts to human health by #KareniaMikimotoi, but blooms of this species can cause large-scale mortality events of marine fauna such as shellfish, echinoderms, crustaceans, and fish. Karenia mikimotoi has been shown to produce several toxic compounds as well as reactive oxygen species, but toxicity is highly variable by strain and the factors contributing to mortality events are still not entirely understood. Although overall concentrations of toxins in K. mikimotoi appear to be relatively low, there is evidence that their effect may be enhanced when the cells come into direct contact with fish gills. Anoxic conditions can also occur when K. mikimotoi cells die in large numbers and subsequent breakdown by bacteria deplete oxygen in the surrounding waters. These anoxic events have also contributed to die-offs."

    What is the history of Karenia in the Northeast?

    "Karenia mikimotoi was first isolated from a coastal lagoon near Woods Hole, MA in 1957 and classified at that time as Gyrodinium aureolum. Since this time, large scale blooms of K. mikimotoi appear to be an emerging problem in New England, with the first occurrence in Maine reported in August, 2017. This bloom was concentrated in the Fore River, Portland Harbor, and parts of the Harpswell coastal waters, and coincided with a die-off of softshell clams in Brunswick, ME. This mortality event cost fishermen $250,000, but a direct causal link between the bloom and shellfish mortality was not established. In August 2019 another bloom occurred in Casco Bay, with no mortalities recorded. Karenia mikimotoi is periodically found in Massachusetts waters, usually in the summer and early fall."

  15. TOP 10 NHL, POINTS
    Is there a pattern viz a clubs’ “hitting percentage” and its success measured as points? It certainly isn’t the obvious one…

  16. It’s December 25. Who has most goals today in the NHL? Majority of those who voted got it right.

    Check #HNOMpoll for my most recent pro hockey question…

  17. 🏒🥅 Hottest goalies since Dec 1 🔥
    Is your guy here? Things are changing as the season matures, as teams either gel or fumble their way towards the year end, mid-season.

    ps. As I said earlier, I’m a fan of goalies. I have a too-thin skin when fans (& pundits) talk “soft goals” and “trade the goalie.”

  18. Only four NHL teams in league history have come back from a three to zero game deficit to win the playoff series.

    The 1942 Maple Leafs did so, defeating the Red Wings to win the Cup. This is the only "reverse sweep" to occur in the Stanley Final.

    The 1975 NY Islanders dynasty did it in the Quarter-Final round against the Pittsburgh Penguins.

    The 2010 Philadelphia Flyers came back from 3-0 to eliminate the Boston Bruins in the Semi-Finals.

    The 2014 LA Kings usurped the San Jose Sharks in the Western Conference Final, They beat the Rangers in the final to capture their second Cup in three seasons. They won three game sevens and set a record for most wins facing elimination in a single season... They won seven.

    Can the Dallas Stars become only the fourth team to accomplish the feat? I say not but, my prognostication is not great this playoff year. The Lightning and Hurricanes are golfing and the Panthers are in the Stanley Cup Final so, what do I know. I was correct predicting that the Bruins would succumb to the "President’s Trophy Curse" but, not until the second round. It's definitely an off year around the board.

    Not that I like it but, Florida will win the Cup. The glass slipper seems to fit and it's definitely been their year, Just ask around Boston and Toronto.
