Big black nemesis, parthenogenesis!?!?
Ol’ Ma Nature, She’s a tricksy one. I found a just-out-of-the-water froglet in my D. pumilio Green 2006 vivarium. Why is that surprising? Long story; here goes… Last summer I got a pair of green pumilio from a friend (and kick-@ss frogger) and within a few weeks I started seeing evidence of breeding activity. In the fall, the friend asked if I had a froglet to spare – he was doing a trade and wanted to include a frog from my pair to get an additional bloodline in the hands of a third breeder. I went to pull the biggest froglet and found a corpse – a few days later I lost what I thought was the female of the pair. I was saddened; I figured that this spring I’d look around for a new female and try again. In late November, I got a little concerned – I hadn’t seen or heard the (supposed) male in over a month – so I went though the viv pretty thoroughly. I found him and heaved a sigh of relief. Yesterday I look in the viv and see a couple of pumilio – one that is smaller than I remember the male being, and a tiny one! For those of you who aren’t dart frog fiends, here’s why I’m shocked – it takes a pair of pumilio to raise a froglet. The pair lay and fertilize eggs on leaves or in leaf litter. When the tads hatch, they are transported to a water-filled bromeliad axil. The female feeds the tadpole special infertile decapsulated eggs (pumilio are known as obligate egg-feeders, along with D. histrionicus and D. lehmanni), often assisted by the male, who will call from tad-containing axils to encourage the female to swing by and feed the kids. If a tadpole is close enough to morphing, it can sometimes make it over the hump if something goes wrong with the food supply, but either I’ve had a tadpole getting along by itself for 3 months or a froglet that I never saw became sexually mature in less than, let’s say, 5 months. Either way, an amazing event. I’m going to call my friend and see if he wants the little guy – it would be good to get another bloodline established in the hobby.
Everybody happy as the dead come home
Big black nemesis, parthenogenesis
No-one move a muscle as the dead come home
Goodbye Brad
Bradford Washburn died last Wednesday. He was 96. To describe him as a legend (at least in New England) doesn’t do him justice. He was a cartographer, a mountaineer, the Director of Boston’s Museum of Science and, of course, a photographer. Of the three who I think of as the holy trinity of New England tech photography (Doc Edgerton, Ed Land and Brad Washburn), he was the one who combined technological achievement with an amazing eye for beauty. A friend of mine ran into Mr. Washburn on the summit of Mount Washington a few years back – Washburn was in his late eighties and still storming around the high places. With respect and admiration – goodbye…
Cell phone strategies
As a measure of how much things have changed – I almost left the ‘cell’ off the title of this post. The lowly land line is that invisible/insignificant. My daughter, who is off on her own, has never – as far as I know – had an old style hard wired phone connection. Enough of that – on to the subject I really wanted to discuss…
Curse you, Steve Jobs! I’ve been thinking about upgrading my cell phone – looking at smartphones like the Motorola Q and the Samsung Blackjack. As I read reviews, it became clear that these phones have a fatal flaw – they lock up and crash. It comes with the territory – with more complexity and with a general purpose OS, Murphy has bigger opportunities for fun and chaos. So, after thinking about it a bit (and admitting that really, what I need a cell phone for is making phone calls) I’d settled on what I’m callling the unix approach – loosely coupled devices, each good at the thing they are supposed to do. A cell, with 3G capabilities for data, to make phone calls on; maybe a Nokia N800 for data/web connectivity; a headset; and so on – all tied together with Bluetooth. Sounds like a plan. Then comes the announcement of of Apple’s jPhone and I’m overwhelmed by techno-covetousness. It’s still very early – I’ll be very interested to see the reviews – but mein Gott, what eye-candy. It is, for sure, pricey, but if it performs as advertised reliably it will be a contender and may knock my plan all to hell. Sounds like Apple is trying to ensure reliability – they may be using what I’ll call the PS/2 software model. Developers will have to get software blessed by Cupertino before it’ll be available (through the iTunes store?) – maybe, again, not a lot of details – it’s pretty clear, though, that the iPhone won’t be an open platform. Time will tell and the cell decision delay is for the best – with the boy going off to college in the fall on one of the 2 US coasts (TBD), there are likely to be more important cell plan considerations – like coverage and minutes.
Later – the Colbert Report on the iPhone – I love the fact that he hits the multiple device v. integrated platform thing:
