I found this is the back yard early in the morning after rain the previous day. I guessed it was some type of fungus, turns out to be a species of plasmodial slime mold called Fuligo septica, commonly known as scrambled egg slime or dogs vomit slime mold!
It really was odd looking, bright yellow, soft and spongy to the touch and underneath it’s really slimy, like a slugs belly.
Slime molds are bizarre and fascinating things, they were initially classified as a type of fungus but this was found to be incorrect. They are now thought of as sitting under the Amoebozoa taxonomic group, a sister group of fungi and animals.
Slime moulds often exist as single cells, but in times of food scarcity they clump together to become a visible gelatinous mass. In this form they can move about as one and are even seen to change shape and function as well as exhibit sensitivities to environmental hazards and food sources. One scientist John Tyler Bonner, observed that they are “no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviours that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains.”
The sea level, rainfall and temperature climate pages have been updated with the latest data from the BOM. As per usual temperature and rainfall are almost up to date but sea level is more than a year behind with the latest reading from December 2013. Why is this?
Always interesting to see how the most recent weather extremes stack up against the last century or so of readings. This most recent summer that felt so hot was nothing special if you look back only 15 years or so, but the longer term trend is clear for sea level and temperature. But not rainfall.
ABC radio has some really good shows, including a whole bunch of science shows. They offer an awesome podcast feed that combines all their science programs plus any scientific segments from other shows into one. ABC hides this feed really well, whenever I have to reload my podcasting app (with my luck with phones, way to often!) it takes ages to locate the feed again.
Well I finally found it, so here it is for the next time I need it, and for anyone else that may enjoy this gem that the ABC hides so well.
Ku-Ring-Gai library has been posting old photos from the area ( including some from Garigal ) to it’s Flickr account . What a great way to make access to it’s archives more convenient. I didn’t even know the library had the photos until I came across one of their online postings by fluke when searching for pictures of Bungaroo.
There are well over 1000 photos in their stream, and they seem to post a new batch every few weeks. Having lived in the area for a while I’ve found it addictive to browse through them and recognize familiar locations back when they were a rugged frontier.
Unfortunately many of the photos are not labeled making them hard to identify, and also hard for people to discover when searching. ( I was lucky to be searching for one of the few photos with a label. ) I wrote to the library asking them if they had any information on the unlabeled photos. They do! They are working on linking the images back to the library catalog and then posting some of the information back to their Flickr stream. Apparently a large and time consuming job, not something that will be done anytime soon. But they did give information on how to search the catalog for information on each photo myself!
Go to http://library.kmc.nsw.gov.au
Click on the “Find information” link on the left hand side and chose catalog. Next, select the advanced search. In the fourth drop down menu labelled “Dewey class”, change this to “Call number”. Type in “photo” in the field along with the last four digits of the flickr photograph title and press search.
For example for the photo labelled “0044593“. Follow the above sets and type in photo 4720.
