Chris Grinter tarafından, on March 25th, 2010 I came across the full-text PDF of the amphibious moth article and extracted the tree showing the radiation of this species group and probable evolution of the amphibious traits. Interesting to note the case shape, and each moth is endemic to its own volcano in the Hawaiian archipelago.
This is a Bayesian analysis of a three gene phylogeny constructed with EF1-alpha, CAD and COI. If anyone wants a copy of the paper, send me a note. Pulled from: Rubinoff D., Schmitz P., Bir endemik tarafından birden fazla su istilası, karasal, Hawaii güvesi radyasyonu. PNAS Mart 2010.

Kurulan din ile yanlış bir şey…
You can read all about his story from the NY Times. Bence bu bütün istismar skandalı ile ilgili korkutucu bir şey (scandalsssss) kilise aslında bu şeytanın işi olduğuna inanmasıdır – bireysel insan değil çarpık zihinleri. Evet, “the Devil is at work inside the Vatican”, so why punish a man who just needs the devil vanquished? Oh wait, they don’t even exorcise priests because it is just a “temptation” with young, deaf, boys. Then how is it that these priests who are so easily tempted left in positions of power? The answer is easy… just like any government, the Catholic church is profoundly incompetent.

Hawaii diğerine inanılmaz hayvan – a completely amphibious caterpillar (Mart ayında yayınlanan 22 PNAS). Birkaç su Lepidoptera olsa, hepsi suya sınırlı tutmak solungaçları var (dinle bak, Biz larva dönemi hakkında sadece bahsediyoruz). Onların dere kurursa, böylece tırtıl yapar. The novel adaptation in these insects is the ability to live comfortably, and apparently indefinitely, on dry land veya submerged in fresh water – a trait distinctive to these 12 new species of Hyposmocoma (Cosmopterigidae). This is unique not only to Insects, but to all known animals. Var, Elbette, amphibians. But unlike these caterpillars they require moisture to survive and often desiccate rapidly. Hyposmocoma thrive in desert like conditions, or submerged for weeks. Not only were 12 different species discovered (that are also the first known caterpillars to eat snails), but it even appears as if this amphibious ability has evolved three separate times. Clearly the selective pressures on small lepidoptera in these areas are extreme.
The Lepidoptera as a whole have evolved a full range of adaptations, including species that are parasitic, detritivorous, fungivorous, endophagous, carnivorous (also on Hawaii), aquatic and now fully amphibious. Hummm, sounds like a bad song (to this music). açıkça, leps are cooler than any other order.
Perhaps if I were Rubinoff I may have named one moth Hyposmocoma aquamana. Elbette, Aquaman was pretty worthless on the land… so maybe it should have been H. potioaquamana (potio- coming from the Latin for superior or more effective).

Bahar Kuzey Kaliforniya'ya geldi ve güveler kanat vardır. Ben hafta sonu Sierra eteklerine kadar hızlı bir gezi aldı ve Amerikan Nehri üzerinde dik yamaçlara kadar gezmiş. Yukarıdaki resimde Xanthothrix ranunculi f. albipunkta (Noctuidae: Stiriinae). Güzel bir California haşhaşının üzerinde oturuyor. ev sahibi bitki, ancak, olduğunu Coreopsis stillmanii ve orta vadi boyunca güneye bakan yamaçlarda küçük serpantin toprak parçaları halinde yetişir.. Burada bir ksantotriks ev sahibi üzerinde oturmak.
Bu güve başlangıçta bir tür olarak tanımlandı. x. Düğünçiçeği içinde 1925 (form kabaca bugün alt türlere eşittir), ve sonra tamamen unutulmuş ve şimdiye kadar görülmemiş 1990. Alt ailenin büyük bir revizyonunun dışında bırakıldı, bu nedenle bir alt tür veya tam tür olarak meşru statü bilinmiyor.. Bizi izlemeye devam edin.
Chris Grinter tarafından, 19 Mart, 2010 Benim favori dizi henüz başka taksit, basının dahi. This article comes from ABC news, kim bu tırtıl belirleyebilir? It is decidedly DEĞİL a gypsy moth.
Fellow entomology blogger Myrmecos had a similar story last week.

The monarchs have started their spring migration north and you might even see one soon (Heyecan verici değil yıl boyunca sakinleri vardır nerede FL veya HI yaşıyorsanız, veya CA ayrı kışlama noktalar var nerede). Meksika'da kış konumlarından Ancak raporlarda kasvetli; with possibly the lowest population size since the colonies were discovered in 70’s. A few bad storms in and along the butterfly’s route, coupled with habitat fragmentation and logging, has probably killed 50-60% of the mexican monarch population (according to reports below).

Is this anything special to be concerned about? I don’t particularly think so. Weather was the key player in this year’s record low population, and I can imagine the butterflies have seen numbers this bad before us humans were around to count them. I will bet anything on the population making a recovery in the years to come, no need to run around screaming, the monarch will be in your garden this summer and next.
Monarchs are pretty and kids love them, so it doesn’t take a stretch of the imagination to figure out why so much effort is put into monitoring them. But as a lepidopterist, nothing is as boring as yet another report on the “plight” of the monarchs Zzzzzzzzzzzz. I tend to believe there are more pressing issues to be concerned about, such as the accelerating rate of biodiversity loss in the face of scientific ignorance. Monarchs do play an important role as a public mascot and even as a figurehead species that help preserve precious habitat – but let’s use them as a foot in the door for further education. Evet, the Monarch Butterfly Fund, is striving for habitat protection and sustainability. A good thing. I understand that this achieves a positive outcome, but why only in the name of the monarch? This seems like a spectacular opportunity for science education that is just rounded down to “save the monarch”. These forests serve as much more than a shelter to one butterfly species and even more than “an important carbon sink and oxygen generator”.
My interpretation.
Instead I suggest this. It is by far, orders of magnitude, more interesting:

Chris Grinter tarafından, on March 13th, 2010 As if educational standards weren’t bad enough in this country, Texas has decided to make them worse. A recent push from a conservative school board has re-written history, literally. The logic may be a bit difficult to follow, but they have attempted to “balance” history by injecting more conservative ideals (dinle bak, no one is a historian on the board). What is to be changed:
- Adding confusion on separation of church and state – (evet, we know it’s not literally in the constitution. Doesn’t mean it doesn’t exist.)
- Discussing how christian ideals helped to found our country.
- Conservative resurgence in the 80’s and 90’s, including the Moral Majority and the NRA.
- Discussing the violent nature of some civil rights movements and republican support of congressional civil rights votes.
- Adding that Germans and Italians were interned as well, not just the Japanese during WWII.
- Adding how senator McCarthy was correct in being paranoid over communism.
- Replacing the word “capitalism” ile “free-market enterprise”.
- Removal of Thomas Jefferson from sections of the book.
This entire change is ghastly. I don’t have a problem mentioning some republican presidents and their positive role in history, or the role of the GOP. History may be written by the victors, but it should strive towards fair and balanced. The alterations made above are absolute bullshit and only serve to further their conservative, religious, agenda. What really pisses me off is the alteration of the civil rights movement and Japanese internment. Just because a bunch of old, fat, white men in congress realized they better pass civil rights laws does not mean they should deserve credit for it. Ve, are they really expecting us to believe that internment was not focused on the Japanese? That entire chapter in our US history is undeniably horrible and shameful, it was also fueled by racism. I do not understand how supporting bigotry and racism is considered a conservative value. Why must they unashamedly, and ignorantly, re-write history to further their agenda? The poisoning of the GOP and conservative values by religion is all to clear in this case. The bread and butter of religious fundamentalism is inculcating the youth. This strategy is very successful when you encourage large families and insane devotion. Now that the majority of conservatives are religious they are spinning their webs onto our children (iyi, your children).
The worst is yet to come. Texas and California are the largest textbook markets in the country. If they pass legislation mandating the alteration of texts then the publishing companies must fall into line. Since printing different versions of books for different states is financially unfeasible, then only ONE book gets printed for US schools. If Texas successfully adds this BS to the history books then every public school in the US gets force fed (or as republicans like to say – rammed down our throats) these books.
What is a conservative today if not religious? What is coming next: insertion of more “balanced” ideals of global warming, cloning and evolutionary biology. Bizi izlemeye devam edin.
Fail to Texas.
