sandlóa, lóuþræll, and lóa

  

A few shorebird photos from Iceland.  Above, sandlóa (in Icelandic) or Common Ringed Plovers (Charadrius hiaticula).  (I really enjoyed hearing their calls.)

Next, a juvenile lóuþræll or Dunlin (Calidris alpina):

 

 

  

And two different views of lóa or European Golden-Plovers (Charadrius apricaria).  Although they were often feeding in grassland sites, we also saw them roosting among rockweeds.

Micro Macro

  

During a beach walk yesterday (17 August 2024), Eric and I came across quite a few Giant Kelp (Macrocystis pyrifera) juveniles, including this very young individual (above) with a very small holdfast and one single blade. 

Most of these juvenile kelps were a little bit larger, but still early in their development.  Here's an example:

 

 

Below, two images show a closer view of the holdfast and the developing blades.  You can see the blades starting to split and the floats just starting to develop (as small swellings at the base of the blades):

 

 

 

 

 

I appreciated coming across these Giant Kelp juveniles and learning more about how they develop.

P.S.  I'm including one more photo just for fun.  The floats are little larger in this individual, and I hadn't noticed at the time, but you can see my reflection in the floats.  A self-portrait in kelp!

 

 

 

P.P.S.  Regarding the title of this post — In casual conversation, we sometimes shorten the scientific name of Giant Kelp, Macrocystis, to "Macro."  And because I am highlighting small individuals in this post, I thought it would be fun to play on those two names = Micro (small) Macro (Macrocystis).

Kelp toes

  

Tiny little kelp toes -- close-up of a Bull Kelp (Nereocystis luetkeana) holdfast attached to a rock.  Washed ashore in Bodega Bay on 27 July 2024.

A local network?

  

Net-of-Cords Kelp (Dictyoneurum californicum) 

Note the interesting reticulated or network-like patterning.  The blade was in the process of splitting into two through the center.

Dictyoneurum has a distinctive holdfast -- strap-shaped, with haptera (branching root-like structures) on both sides.

 

 

[This kelp had washed ashore, so I placed it on a rock to take a photo, but this kelp lives much lower in the intertidal zone.]

Summer gold

Birds of a different feather

  

A few more miscellaneous bird photos from Hawai'i for you...

Above, a kōlea, or Pacific Golden-Plover (Pluvialis fulva), all dressed up for the breeding season and departing soon for the Arctic tundra.

 

 

 

Close-up of a nēnē , or Hawaiian Goose (Branta sandvicensis), endemic to the Hawaiian Islands.

 

 

 

 

A distant photo, but these were my first kioea, or Bristle-thighed Curlews (Numenius tahitiensis).

 

 

 

Also distant, but fun to see a pueo, or Hawaiian Short-eared Owl (Asio flammeus sandwichensis).

 

 

 

An ‘ūlili, or Wandering Tattler (Tringa incana) on a nice bed of limu kala. (I think this might be Sargassum aquifolium, formerly S. echinocarpum, but feel free to correct me!)  This endemic species is the state seaweed of Hawai'i and an important alga used in cultural practices by native Hawaiians.

 

 

 

‘Ā, or Brown Booby (Sula leucogaster).

Thanks for tuning in for some special guests from Hawai'i!

A bigger anchor

 

 

I was leading a walk about seaweeds today and we encountered a few of these Bull Kelp (Nereocystis luetkeana) holdfasts attached to small rocks.  The rocks likely served as anchors when the kelp was small, but once they grew larger these rocks just weren't heavy enough to keep the kelp in place.

 

 

 

Fun to see the little kelp "feet," but maybe next time the microscopic stage of the kelp will find a larger rock.  You know the famous quote, "You're gonna need a bigger boat anchor."  ;)
