  1. Good tips, thanks for the info. That's what I figure with the tunes too, ultimately bot allowing seedlings to get rootbound is the best approach. Do you make your own media? Or what the native mix from somewhere like ANL be adequate? Given this first stage will be a trial, I'm really looking for optimal success rates to help guarantee that it will be scaled up.
  2. Also, any input on whether those tubes with internal ribs really do promote beneficial root development?
  3. That's right, Skellum, it'll be a diverse range of species from grasses and groundcovers through to trees. I was hoping you'd reply, @waterboy 2.0. That's exactly what I was thinking, grow them hard to reduce mortality later. Shade is definitely a consideration for understory species. What do you think of a tunnel with wire mesh, and shade at one end, to protect from animals? Pallets or pallets on crates as benches?
  4. Interested in hearing how you're using your still air box / how you've made it. I expect that if technique is your problem, using a laminar flow hood will not help you much.

    Logged on for the first time in a while and tried to send a PM to another member. Unfortunately, the dialogue box for the message body appears to be broken. The dialogue boxes for the recipient name and subject are fine, and can be written in, but the message box isn't present. Can this be fixed, please?

    I tried that, but the field is still not there, just a message that it needs content in it.

    Pleurotus nebrodensis

    Hey Will, if this is the culture you received from me many years ago, I've always questioned whether it really is Pleurotus nebrodensis. If memory serves me correctly, I received the culture from Paul (speedy); I'm not sure how he came to the conclusion it P. nebrodensis. Interestingly, looking into it again now, I see Aloha Medicinals sells a culture of it (and uses one of my photos without permission - seems to be a few sites doing that with my photos), originating from China. This article discusses some of the relevant taxonomy if you're interested. Anyway, good to see you're enjoying the fruits of your labour!

    Post your track of the day

    Can't believe this thread is still going. I almost feel bad for starting it. It's become an immense, unwieldy beast, squandering bandwidth on a site that has historically, and continues to, struggle to meet server costs.
  12. Couldn't agree more. Entheogenesis is an incredible collaboration, which brings together people from all walks of life, and with a very diverse set of backgrounds, interests, and approaches to the questions and subjects discussed at these events. Hard to believe how many years have passed since the last outdoor event. I'll be there 100%.

    Ephedra in Kyrgyzstan & Tajikistan

    The latter, but I knew they would be around and was looking for them the whole time. There were many other beautiful and interesting plants in the region too, but I decided only to post photos of the Ephedra species. And for the record, so that others don't ask, I did not collect any seed.
  14. Been a long time aince I last felt the compulsion to post here, but this article is just so incredible that I had to share it here. Hope some of you find it as much of an incredible read as I did. Bread Wheat Genome Contains “Shocking” Plot Twist By Jennifer Frazer | July 18, 2014 "Wheat P1210892" by Copyright © 2007 David Monniaux - Own work. Licensed under CC BY-SA 3.0 via Wikimedia Commons. Yesterday scientitsts announced in a quartet of papers in the journal Science that the draft genome of bread wheat -- Triticum aestivum -- had been decoded and mapped. Together with barley, wheat is the crop on which civilization rose in the Fertile Crescent and Egypt some 10,000 years ago. With theses grasses and the help of wild yeast, humans created bread and beer and have rarely looked back (Prohibition and the current gluten-free fad being notable exceptions). I covered the story over at National Geographic. The content of the genome was not a surprise, Robert Bowden, supervisory research plant pathologist at the U.S. Department of Agriculture's Hard Winter Wheat Genetics Research Unit in Manhattan, Kansas, told me. What was unexpected, he said, was what the genome told scientists about the evolution of wheat, as detailed in a second paper released concurrently with the genome by Marcussen et al. In the genome, "we found pretty much what were expecting," Bowden said. "The second paper was the one was the one that was kind of shocking, because we thought we understood a lot about the evolution of wheat.” Indeed, scientists did understand a lot about the evolution of wheat. But they didn't know everything, hampered by a lack of wheat fossils and by the intractably large and repetitive wheat genome, which had resisted sequencing. You can read more about that story over at Nat Geo. For example, scientists had known for some time that wheat is a triple "polyploid", a hybrid of three parent species of wheat who through two accidents of biology had merged two genomes into one to produce emmer or durum wheat (used primarily for pasta today, though probably for different purposes by the ancients), and then two into three to produce bread wheat with a genome three times as big as that of its ancestral genomes. You can read more about this process in a blog post I wrote about polyploidy in plants here. But without a map of the genome, answering questions about how the three parent species of wheat were related to each other (they were presumably close relatives) was difficult to impossible. Then along came the draft wheat genome, and suddenly lots of things were possible. Thomas Marcussen, Odd-Arne Olsen, and Simen Sandve of the Norwegian University of Life Sciences and their colleagues in Norway, Germany, and the UK initially set out to date the two known polyploidy events and find out how the three wheat parents were related to one another – a topic that had been controversial for some time due to the fossil and genome void. They expected a bifurcating tree in which two of the parent species -- they were not sure which two -- were more closely related to each other than the third. Instead, they discovered a more complex situation. Instead of two hybridizations in wheat's past, there now appeared to be three. “We really couldn't make a model that look liked a normal bifurcting tree based on our data,” Sandve said. “We had to try to make it into a network to make an evolutionary model that would fit the data.” Wheat parents Triticum urartu and Aegilops speltoides were equally closely related to Parent #3 Aegilops tauschii and more closely related to A. tauschii than to each other. That could only make sense if the ancestors of T. urartu and A. speltoides had hybridized to produce the ancestor of A. tauschii via a process called monoploid hybridization. This type of hybridization can only take place between two very closely related species. It happens when a normal egg cell from one species meets a normal sperm cell from another and the species are not so distantly related that the sperm can't fertilize the egg. A familiar example is the production of a mule from the mating of a donkey to a horse -- two different species. In that case, the mule is usually infertile, but in the case of wheat, A. tauschii was evidently good to go. In short, the wheat family tree is beginning to look distressingly similar to the Hapsburgs'. "It's complicated": The convoluted family tree of wheat. AA = T. urartu, BB = Ae. speltoides, and DD = Ae. tauschii. AABB = emmer/durum wheat (T. turgidum), and AABBDD= modern bread wheat, T. aestivum. The first speciation event is homoploid hybrid, the second two are polyploid (as seen by chromosome copy increase). Images show extant wheat closely related to respective species. The circles indicate dates of hybridizations in millions of years ago. The lines connecting A and B to D are what's new here. Fig. 3 from Marcussen et al 2014. Click image for source. The discovery fits with other data in plants like sunflowers that seem to show that this type of direct hybridization that seems to have produced A. tauschii – called homoploid hybridization – may be more common in plants than previously thought, Sandve said. Bowden said he was taken aback by these results. “Instead of there being two speciation by hybridization events in the evolution of wheat, there's three, which is shocking. I don't think anybody was expecting that,” he said. “If it's true, and I think it is true, it's a really really unexpected result and shows the power of this method of analysis and leveraging all the data that [the draft genome] produced.” He said they would have to rethink how they approached mining the A. tauschii genome for useful traits for new wheat varieties. Although it no doubt still contains valuable traits, it is no where near as old or independent of the T. urartu and A. speltoides subgenomes as they had thought, the said. In addition, from an evolutionary perspective, he said, it's intriguing that the ancestral T. urartu and A. speltoides genomes hybridized twice in two different ways – once to make homoploid hybrid A. tauschii, and once in polyploid fashion to produce emmer/durum wheat (T. turgidum). “It's very interesting that these two different kinds of event happened with the same two species to start with,” he said. “and it also says 'Wow, this is not very rare. It happened three times just in the evolution of wheat!'” Source.

    Potting Mix Poppers

    Not this species. Probably a Parasola or Coprinellus species, maybe another Coprinopsis species, hard to say. C. atramentaria is considerably more robust than the mushrooms pictured.

  19. I'm pretty sure I've eaten D. kutejensis, though didn't realise it at the time. Thought it was just a different cultivar of D. zibenthinus. Maryoto, does D. kutejensis have quite a thin layer of flesh around the seed? And a small fruit comparatively? Would love to try those other species. I've eaten Artocarpus integer (cempedek) in Borneo, which was delicious.

    Ebola. Latest developments thread.

    This is the only article you need to read on the subject, i.e. stop taking shit out of context and calm down. Transmission is only possible through contact and in the unlikely event that it did spread to somewhere like Aus or the US, it would not spread far. We have very effective containment protocols in place. The irrationality of people is absurd sometimes. Terrifying Ebola 'facts' for enhanced scaremongeringThe current Ebola outbreak in West Africa is the worst in recorded history, but it has also led to an outbreak of media scaremongering that really isn’t helping. So to pre-empt further hysteria, here are some terrifying-but-unlikely ‘facts’ about Ebola that may be gracing the front pages soon Even reading about Ebola in posts like this might be dangerous … why are you still reading this? … Good god, STOP! Photograph: David Levene Ebola is no laughing matter. Let’s make that clear from the start. It is a deeply unpleasant and dangerous disease, with a fatality rate of up to 90%. In lay terms, for every 10 people who get it, only 1 survives, making it among the most lethal diseases known to man. There is no known cure or vaccine (although experimental drugs are being tried). The onset is sudden, but the incubation period ranges from 2 to 21 days, so if you’ve got it you won’t know straight away. And the symptoms are, frankly, horrific. Even the initial symptoms are unpleasantly flu-like (proper flu, not “don’t want to admit it’s just a cold” flu). Muscle pain, weakness, headache, sore throat, Ebola can cause all of these. And that’s just for starters. It quickly moves on to causing vomiting, diarrhoea, rash, impaired kidney and liver function, and sometimes both internal AND external bleeding. This blood loss invariably leads to death. These details aren’t from some blog written by a paranoid hypochondriac obsessed with worst-case scenarios. They are from the World Health Organisation Ebola factsheet, almost a textbook definition of a “reliable source”. All in all, the Ebola outbreak is awful, and those suffering from it deserve all possible support and sympathy for what they’re going through, while those trying to tackle the problem deserve all manner of praise and respect. However, despite all the dreadful things about this outbreak, if you go by media coverage, the worst thing about it is that it might end up affecting people in the UK, US or similarly developed wealthy nations. And we can’t have that now, can we. Actually, perhaps that’s a bit harsh. Thanks to 24-hour rolling news and the internet, those of us in the developed world are constantly spoiled for choice when it comes to hearing about how absolutely awful things are happening to people in other countries. With such a constant bombardment of bleak information, it is perhaps to be expected that people will prioritise and preferably want to hear about things that may directly impact their lives. But much of the media seems to have readily descended into scaremongering to gain readers/traffic, and we know how dangerous scaremongering can be. Some media sources have tried to present a calm, rational, reflective report of the Ebola situation. Kudos to them. But sadly, many others haven’t been so restrained. Such scaremongering and provocative reporting can only harm public understanding and potentially jeopardise the effectiveness of any response to an actual occurrence of the disease, as some have noticed. As well as this, paranoia coupled with poor understanding leads people to act irrationally. I say this as someone who knows people who, during the early stages of the 2009 Mexican swine flu scare, cancelled a planned trip to a Chiquito restaurant in Cardiff, a Mexican themed eatery half a planet away from the affected area. There’s “cautious”, and there’s … whatever you’d call this. However dangerous it may be, Ebola can (at present) only be contracted by exchanging fluids with an infected sufferer, through the mouth, eyes, nose or other access point to inside the body. Ebola is a tenacious virus and strict precautions must be taken when dealing with it. However, you’re not going to get it just because you were on the same landmass as someone who has it. Having said all this, if the mainstream media will insist on scaremongering about Ebola, here are some terrifying “facts” about Ebola that they could use, with my blessing. Better they use those than scapegoat innocent people, I guess. The Ebola virus can be up to 14,000 nanometres in length. That’s surprisingly large for a virus, but still too small to see with the naked eye. But if it were the size of a car, it could kill you if dropped on you from even a modest height! Ebola is not the deadliest virus known to mankind in terms of number of overall deaths caused, but if it ends up causing more deaths than the deadliest virus known to mankind, then Ebola would be the deadliest virus known to mankind! Some have reported that the Ebola outbreak could be much worse than is believed due to the full number of cases not being reported. However, if you’re basing conclusions on information we don’t have, there’s no limit to how many people might have Ebola. You, the one reading this, could have it right now! We don’t have any information to suggest otherwise, so who’s to know? Vox recently reported that if the supercontinent Pangaea were to reform today, the US would border the Ebola epidemic locations, which would obviously make it easier for the virus to spread. While this may be true, we can take comfort from the fact that, if all the continents on Earth were to suddenly rearrange themselves, the resultant geological, environmental and societal devastation would achieve apocalyptic levels several times over, so a localised (if deadly) virus would be way down on the list of concerns for whatever is left of the human race at this point. Ebola is believed to be carried by fruit bats, and the wastes or meat from such bats is believed to have caused the current outbreak. Bats are common throughout the world, and some are believed to be vampires in disguise, and vampires can sneak into your bedroom and drink your blood as you sleep. If the vampire that bites you transforms into an Ebola-carrying bat, then this would be a sure-fire way of contracting Ebola. You can’t be too careful, after all. If you laid out all the recorded victims of Ebola end-to-end, the end result would be so horrific as to defy description, and you’d probably be arrested and/or placed in a high-security psychiatric facility for having done such a grotesque thing. Some have claimed that homeopathy can be used to treat Ebola, but there is no scientific evidence to support such a claim. This still applies if you replace “Ebola” with TB or Aids or influenza or bronchitis or Sars or bird flu or swine flu or rhinovirus or Legionnaires’ disease or Parkinson’s or Huntington’s or gout or athletes foot or gum disease or gallstones or ME or cerebral palsy or kidney stones or heatstroke or arrhythmia or hypotension or hypertension or basically anything that is inconsiderate enough to be an actual illness with a biological mechanism.
