The following description of the inoculation process at Dorena is excerpted from pages 72 and 73 of the Whitebark Pine Restoration Strategy for the Pacific Northwest Region. 2009–2013 (available here: ecoshare.info/uploads/documents/WPB_Strategy_PNW_093008cl...):
"The Dorena Genetic Resource Center (Dorena), a component of the regional genetics program of Pacific Northwest Region (and a partner with the regional Forest Health Protection group), has established protocols for blister rust resistance testing of whitebark pine. These protocols are based on those developed and successfully used for screening of western white pine (P. monticola) and sugar pine (P. lambertiana) over the past 5 decades (Danchok et al. 2003).
Resistance testing involves inoculation of young (usually 2-year-old) seedlings with spores of C. ribicola and evaluation of seedlings for up to 5 years after inoculation. Inoculation usually takes place in late August or during September (which coincides with time of natural infection in the field). Seedlings are moved into a climate-controlled inoculation chamber. Temperature within the inoculation chamber is maintained at around 16.7° C (62° F) and relative humidity at 100 percent.
Ribes spp. are the alternative host for C. ribicola, and spores from infected Ribes spp. are necessary to infect the pines. Ribes spp. leaves infected with C. ribicola at the telial stage are collected from forests in Oregon and Washington or from the Ribes garden at Dorena. The Ribes leaves are placed on wire frames above the seedlings, telial side down. Spore fall is monitored until the desired (target) inoculum density of basiospores is reached for each box; the Ribes leaves are then removed. After the target inoculum density is reached for the last box, the temperature is raised to 20° C, and the seedlings are left in the inoculation chamber for approximately 48 hours to ensure spore germination and infection of the pine needles.
Following inoculation, the seedlings are transported outside. The seedlings are evaluated over a period of 5 years for the presence of disease symptoms and mortality. The first symptoms to develop are needle lesions, or ‘spots.’ These are typically assessed approximately 9 months and 1 year after inoculation. Presence and number of stem symptoms along with mortality is assessed annually for 5 years after inoculation."

The Mallard, or Wild duck (Anas platyrhynchos[1]), probably the best-known and most recognizable of all ducks, is a dabbling duck which breeds throughout the temperate and sub-tropical Americas, Europe, Asia, New Zealand (where it is currently the most common duck species), and Australia.
The male birds have a bright green head, while the female's is light brown. The Mallard lives in wetlands, eats water plants, and is gregarious. It is also migratory. The Mallard is the ancestor of all domestic ducks, and can interbreed with other species of genus Anas.[2] This interbreeding is causing rarer species of ducks to become genetically diluted.
The Mallard is 56–65 centimetres (22–26 in) long, has a wingspan of 81–98 centimetres (32–39 in), and weighs 0.9–1.2 kilograms (32–42 oz). The breeding male is unmistakable, with a bright green head, black rear end and a yellowish orange (can also contain some red) bill tipped with black (as opposed to the dark brown bill in females), and is also nature's most feared duck. The female Mallard is light brown, like most female dabbling ducks. However, both the female and male Mallards have distinct purple speculum edged with white, prominent in flight or at rest (though temporarily shed during the annual summer moult). In non-breeding (eclipse) plumage the drake becomes drab, looking more like the female, but still distinguishable by its yellow bill and reddish breast.
In captivity, domestic ducks come in wild-type plumages, white, and other colours. Most of these colour variants are also known in domestic Mallards not bred as livestock, but kept as pets, aviary birds, etc., where they are rare but increasing in availability.
A noisy species, the male has a nasal call, the female has a "quack" stereotypically associated with ducks.[3]
The Mallard is a rare example of both Allen's Rule and Bergmann's Rule in birds. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds. Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimize heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. Examples of this rule in birds are rare, as they lack external ears. However, the bill of ducks is very well supplied with blood vessels and is vulnerable to cold.

I will probably delete this explanation later.
I had genetic testing today to see if I have a genetic mutation that might explain why I developed breast cancer at such a young age. Between you and me and the lamp post, I don't think I have the mutation but I wanted to rule it out because if it turns out I have it, I will probably have my ovaries removed.
Nobody else in my family has had this test because they don't trust the insurance companies. But in my case the "cat is already out of the bag" for me because I am sure I would never get insurance anyway because of my "history".
btw this photo was a bitch to take in my dark apartment and no flash. One handed shooting here with a mono-pod and a 1.8 .
this is the crazy tree I told you guys about from the golf course around the corner from our house... I dont get it...

An international team of scientists led by University of Hawaiʻi at Mānoa researcher Joanne Yew may have discovered a new and effective way to control insect pests that are a threat to agriculture and humans. Yew and her team identified a gene in vinegar flies responsible for the insect’s waterproof coating, which provides them protection from microbes and environmental stress. They nicknamed the gene spidey and announced the findings in a recently published study in PLoS Genetics.

Planted tanoak seedlings. Field trial to examine genetic variation in resistance to Sudden Oak Death (Phytophthora ramorum) in tanoak, Douglas-fir, coast redwood, and Port-Orford-cedar. Established near Brookings, Oregon.
More about the project from Richard Sniezko:
A field trial was established in southern Oregon, near Brookings, in March 2019 to examine genetic variation in resistance to Phytophthora ramorum (pathogen causing Sudden Oak Death) in tanoak, as well as susceptibility of conifers Douglas-fir, coast redwood, and Port-Orford-cedar. The trial was a joint effort between USFS (Dorena Genetic Resource Center, FHP), OSU, and ODF.
900 tanoak (Notholithocarpus densiflorus) seedling ‘families’ from 55 Oregon parent trees (and bulked lots) were planted in a field trial to assess genetic resistance to Phytophthora ramorum (pathogen causing sudden oak death, SOD), and to correlate with results of seedling inoculation testing done at Oregon State University. Douglas-fir (Pseudotsuga menziesii), coast redwood (Sequoia sempervirens), and Port-Orford-cedar (Chamaecyparis lawsoniana) seedlings were also planted to test conifer susceptibility.

CAOFEIDIAN GENETIC CITY 曹妃甸进化城
CHINA’S MOST AMBITIOUS ECOCITY YET!
中国最有抱负的生态城！展览-论坛-总规
Urban China is booming...but still without any real vision. Now the
green city is on the agenda across the nation this must change. The
project Caofeidian–Genetic City is China’s most ambitious response to
the triple-challenge of explosive growth, environmental pressure, and
healthy human desires for the future. A project that exposes the
current green models will not suffice.
中国的城市建设如火如荼……关于城市的远见卓识却仍然缺位。当绿色城市已登上国家的议事日程表之时，这必须被改变。曹妃甸进化城项目是在中国最有抱负的探索，它试图同时回应三重挑战——城市的爆炸性增长、环境的压力以及人类对未来的欲望。一个暴露目前绿色城市模式不可持续的项目。
CAOFEIDIAN ECOCITY – GENETIC CITY
Caofeidian is a new coastal city next to Tangshan in Northern China.
While currently empty, the population is anticipated to rapidly exceed
1 million. Caofeidian Ecocity is part of a $50bn industrial zone
including a deep water port, some of the largest steel production
plants in the world, and expansive oil refineries. This is the
economic thrust behind the large-scale local urbanization.
How to build a new sustainable city is the most compelling problem
facing planners today. To tackle this, for Caofeidian the DCF proposed
a radical new evolutionary design method. Ten world renowned
architecture practices were asked to plan not all at once, but in
relay to achieve a proposal for Caofeidian Genetic City in the year
2040. Evolving through stages, this evolutionary process simulates a
city with an organic inner logic.
曹妃甸生态城 – 进化城
曹妃甸是位于华北地区邻近唐山市的一座新兴海滨城市。虽目前仍然空旷，但曹妃甸的城市人口将很快过百万。曹妃甸生态城是投资500亿美元工业区的一部分，有大型深水港，还有名列世界前茅的钢铁厂。这些都将是当地城市化背后的经济推力。
如何缔造全新的可持续的城市将是城市规划者今天需要迫切解决的问题。动态城市基金会向曹妃甸提出了激进的全新的进化设计方法，以探索这一问题的解决。十家世界知名的建筑事务所受邀参与了这一次规划，他们不是同时进行，而是以接力的方式为曹妃甸进化城2040年的总规提出不同时间段的方案。通过在不同时期的演变，这一进化过程试图模拟城市天然的生长逻辑。
EXHIBITION
The results of the Genetic City project will be exhibited at the
Shanghai World Expo in a stunning multimedia installation. A 45m long
screen provides a 360° continuous animated panorama of the new eco
city. Step by step, in interviews and presentations the progression of
the city growing with time, is presented.

North Park phacelia grows on barren sandy soils in North Park, Colorado near the town of Walden. In this photo, botanists are taking genetic samples of the species to analyze its genetic similarity to other Phacelia species in Colorado.
Photo credit: USFWS
...........................................................................
BACKGROUND:
North Park phacelia (Phacelia formosula) is a member of the waterleaf family (Hydrophyllaceae) is found in “North Park” of north central Colorado, near the small town of Walden. The bright purple flowers and lobed leaf margins make this species easy to spot in July and August. The plant is a biennial, surviving for one year as a rosette of leaves before flowering and dying the following year. The plant is found on barren exposures of the Coalmont Formation that are easily eroded (see the habitat pictures). Roughly 16,000 individuals are known from six separate populations and the entire species is known from an area measuring roughly 10 miles in either direction (north to south, east to west).
The species was discovered, at one location, in 1918 by the Colorado botanist, George Osterhout. Additional sites were not located until 1979. Because of the limited distribution, small population sizes and threats to the species, North Park phacelia was listed as endangered under the Endangered Species Act in 1982. Threats to the species today include: heavy livestock use, off-road vehicle traffic, oil and gas development, residential development, a lack of regulatory mechanisms, and potential effects from climate change.
Genetic and taxonomic research into the species’ relationships with close relatives in Larimer and Grand counties is underway. Further locations of these Phacelia are being sought to better understand these relationships.
Several populations of North park phacelia occur either partially or wholly on private and State lands. Conservation actions on these properties are voluntary. Funding is available to landowners wanting to conserve the species. Please contact Gina Glenne or Ellen Mayo at 970-243-2778 for further information on this species and ways that you can help with conservation and recovery.

There are somewhere between 50 and 60 native orchid species in the UK.
I say it like that because as genetic sequencing is used, what was once a separate species becomes a sub-species of something else.
And then with the availability of orchid plants and seeds on the net, the "chance" discovery of more and more exotic species becomes ever more likely.
Of the top of my head, these are the species I have yet to see.
1. Narrow Lipped Helleborine 2. Creeping Lady's Tresses 3. Irish Lady's Tresses 4. Lesser Twayblade 5. Coralroot 6. Bog Orchid 7. Irish Spotted Orchid 8. Small White Orchid 9. Dense Flowered Orchid (though seen on Rhodes) 10. Dune Helleborine (though seen both Tyne and Lindisfarne(though the latter was a separate species in 2014)) 11. Ghost Orchid. (of course) 12. Pugsley's Marsh orchid
And until yesterday, Red Helleborine.
Some are rare due to geographical location limitations, and some are low in actual numbers, some, both. The Ghost I probably won't see, but of the others, the blandly names Small White Orchid might prove to be the most difficult.
The Red Helleborine was never that common, but since the war its best sites have been built on, and what sites are left have at times poorly managed. Most years less than five plants flower, some years just one. So, the chance to see one of the sites, and as it turns out the only one with flowering spikes this (and last) year was too good to turn down, and after the hours put in last week, I thought I would claw some back this week by taking Tuesday off.
It would mean having the car all day, and driving to the Chilterns and back in one day, but what the heck? The trip was arranged by the Hardy Orchid Society, I put my name down and was accepted.
We were up at five, Jools made drinks and then had a shower, I dragged my body out of bed, got dressed and got all my shit together.
We left at quarter to six, me dropping Jools off on Hythe seafront, and then heading back to the motorway before taking the M25 south round London. I knew it would be tough, but I had four and a half hours for a two and a half hour drive.
Should have been enough.
I won't lie, travelling along the M25 and then round the M25 is not pleasant. Even in glorious sunshine. Traffic was stop/start for over an hour, and then the sat nav declared that the motorway ahead was closed.
I said to the sat nav, if that were true, I'm sure the matrix signs would have mentioned it.
The motorway is closed, it said.
Again.
So it came to pass that I was travelling at between 60 and 70mph along what the car told me was a closed motorway. So, I had no estimated time for arrival, only that the alternative routes were to take much longer than I had.
So, once the car agreed with me that the motorway wasn't closed after all, and with the expected delays taken into account, I would still get to the site with an hour to spare.
Good news.
It was great to turn off the M25 at the junction after Heathrow, head to Oxford, but have enough time to be able to stop at High Wycombe services for a comfort break, then call in at Greggs for not one, but two sausage rolls for second breakfast.
I was boosted by their energy for the last half an hour drive to a lay by in a wood, where the warden was already waiting.
As time went on, more and more cars arrived, so soon over a dozen folks had arrived, and at half ten we had our brief and we walked into the woods.
Because there was a clay pigeon shoot on at the landowner's estate, it was like being in a warzone, but walking carefully down the chalk slope through dense woodland, we came to a stockade, and on the other side were two weedy looking spikes with glorious pink flowers.
One hundred and seventy nine. Red Helleborines.
We took turns to take shots, some took a few, other apparently took hundreds.
I suppose I should mention I was recognised by the organiser, Richard, and a couple who asked: did we meet at Homefield Wood where you pointed out orchids we should look at?
I'm ready for my close-up, Mr. DeMille Yes, that was me.
And another couple when I said I bumped into a friend of us both at Goring railway station on the way to Hartstock, they said they were in the minibus waiting for their driver, Duncan, to take them somewhere else.
Small world.
Is the orchid world.
After 90 minutes we were done, so we walked back to our cars, and with it being after midday, I knew I had to make tracks to head back to Kent.
So, programmed the sat nav for home, and away I zoomed.
I had no idea what the traffic would be, but the matrix signs told me the southern way round would be delayed by an hour at least, so I went clockwise round via the Ma, A1, M11 and A12 to Dartford.
There were no delays, and arrived at the bridge in good time. So the plan then was to call in at The Larches to check on the Broad Leaved Helleborines. Dashing down the M20 then up Detling Hill, turning off onto Pilgrim's Way, parking at the side of the road.
The site was very dry indeed, and I found just one spike in the whole of the large clearing, none under the two lonely trees at the top, nor between them and the path beside the wood.
Along the path I found maybe a dozen spikes of good size, about two weeks from flowering. PLenty of Ringlets about too, but none settled long enough for me to take shots. So, having looked for the orchids, I walked back to the car, and with over two hours to kill before I had to pick up Jools, I thought I would go to Hothfield to look at the Heath Spotted Orchids again, and at the Keeled Skimmers which I knew now was their only Kent site.
I was hot and hungry, but told myself I would call in at a garage once I had these last shots for some pop and crisps, so was happy to park on the main road, grab the camera and set off through the wood.
Into the fenced off area, and the overgrown birch was even worse than in May when I was here last, though there were a few Heath Spotted spikes, not as numerous as in previous years.
But onto the boardwalk I stood for over half an hour watching the Keeled Skimmers flying, baking, mating, egg laying. It was like an air show, and wonderful.
A lady came to see what I was taking shots off, and she pointed out the orchids growing in the dried out mud.
I see those too at Blean Woods, she said.
No you didn't, I said as nicely as I could.
I then pointed out the difference between CSO and HSO, the lip shape, patterns and PH of the ground, and she was amazed. As she was at the dragonflies too.
I had my shots of orchids and dragons, so walked back up the hill to the car park, then drove to the main road and down to the garage where I filled the car and bought a bottle of lemon Fanta and two bags of paprika crisps. Which I ate driving into Ashford, then along the M20 driving to Hythe.
I was an hour early, and I had toyed with the idea of going to a pub, but decent ones are thin on the ground in Hythe, so I sat on the prom for half an hour, looking at the sea and the slight waves lapping at the stony beach, while teens swore at each other in what they though was a really funny and grown up way.
I drove to the factory and waited for knocking off time, the hooter went and they all came tumbling out, I picked Jools up, and we drove through the town and up and over the down to junction onto the motorway, then back home.
Phew, what a long and tiring day.
Home I warm up some pasta sauce, heat some gnocchi, and within ten minutes we were sitting down to eat.
Not great, but good enough.
I even resisted the lure of wine. Oh no I didn't. I had three glasses. It was the night before I had squash.
Tanoak infected with SOD. Field trial to examine genetic variation in resistance to Sudden Oak Death (Phytophthora ramorum) in tanoak, Douglas-fir, coast redwood, and Port-Orford-cedar. Established near Brookings, Oregon.
More about the project from Richard Sniezko:
A field trial was established in southern Oregon, near Brookings, in March 2019 to examine genetic variation in resistance to Phytophthora ramorum (pathogen causing Sudden Oak Death) in tanoak, as well as susceptibility of conifers Douglas-fir, coast redwood, and Port-Orford-cedar. The trial was a joint effort between USFS (Dorena Genetic Resource Center, FHP), OSU, and ODF.
900 tanoak (Notholithocarpus densiflorus) seedling ‘families’ from 55 Oregon parent trees (and bulked lots) were planted in a field trial to assess genetic resistance to Phytophthora ramorum (pathogen causing sudden oak death, SOD), and to correlate with results of seedling inoculation testing done at Oregon State University. Douglas-fir (Pseudotsuga menziesii), coast redwood (Sequoia sempervirens), and Port-Orford-cedar (Chamaecyparis lawsoniana) seedlings were also planted to test conifer susceptibility.
