Di Chris Grinter, il 25 marzo, 2010 Mi sono imbattuto il full-text PDF dell'articolo falena anfibia e estratto l'albero che mostra la radiazione di questo gruppo di specie e probabile evoluzione delle caratteristiche anfibie. Interessante notare la forma del caso, e ogni falena è endemica al proprio vulcano dell'arcipelago hawaiano.
Si tratta di una analisi bayesiana di una filogenesi tre gene costruito con EF1-alfa, CAD e COI. Se qualcuno vuole una copia della carta, Mi inviare una nota. Tirato da: Rubinoff D., Schmitz P., Più invasioni acquatiche da un endemico, terrestre, Radiazioni falena hawaiana. PNAS marzo 2010.

Niente di sbagliato con la religione stabilita…
Puoi leggere tutto sulla sua storia dal New York Times. Penso che la cosa più spaventosa di questo scandalo tutto abuso (scandalo) è che la chiesa crede realmente che questa è l'opera di satana – non le menti contorte dei singoli esseri umani. Sì, “il Diavolo è all'opera all'interno del Vaticano”, quindi perché punire un uomo che ha solo bisogno che il diavolo sia sconfitto? Oh aspetta, non esorcizzano nemmeno i sacerdoti perché è solo un “tentazione” con i giovani, sordo, ragazzi. Allora come mai questi sacerdoti, così facilmente tentati, hanno lasciato in posizioni di potere? La risposta è facile… proprio come qualsiasi governo, la Chiesa cattolica è profondamente incompetente.
Di Chris Grinter, il 25 marzo, 2010 For all those who abstained from voting (I want to assume some readers must have known the identity of our mystery caterpillar, but were too lazy to comment), here is the answer (after the break).

Another amazing animal from Hawaii – a completely amphibious caterpillar (published in the March 22 PNAS). While there are a few aquatic Lepidoptera, all of them have gills that keep them restricted to the water (mind you, we are talking only about the larval stage). If their stream dries up, so does the caterpillar. The novel adaptation in these insects is the ability to live comfortably, and apparently indefinitely, on dry land o 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. Esistono, Certo, 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). Chiaramente, leps are cooler than any other order.
Perhaps if I were Rubinoff I may have named one moth Hyposmocoma aquamana. Of course, 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).

Spring has come to northern California and moths are on the wing. I took a quick trip up to the Sierra foothills over the weekend and hiked up the steep slopes above the American River. Above is pictured Xanthothrix ranunculi f. albipuncta (Noctuidae: Stiriinae). It happens to be sitting on a beautiful california poppy. The hostplant, tuttavia, è Coreopsis stillmanii and grows in small patches of serpentine soils on southern facing slopes along the central valley. Qui è un Xanthothrix sitting on the host.
This moth was originally described as a form of X. ranunculi in 1925 (form roughly equals subspecies today), and then completely forgotten about and unseen until 1990. It was left out of a major revision of the subfamily, so the legitimate status as a subspecies or full species remains unknown. Stay tuned.
Di Chris Grinter, on March 19th, 2010 Yet another installment of my favorite series, the genius of the press. This article comes from ABC news, who can identify this caterpillar? It is decidedly NON 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 (not exciting if you live in FL or HI where there are year-round residents, or in CA where there are separate overwintering spots). Reports from their winter locations in Mexico however are dismal; 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. Scommetto qualsiasi cosa sulla ripresa della popolazione negli anni a venire, 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. Sì, gli 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:

Di Chris Grinter, 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 (mind you, no one is a historian on the board). What is to be changed:
- Adding confusion on separation of church and state – (sì, 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” with “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. E, 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 (well, 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. Stay tuned.
Fail to Texas.
Di Chris Grinter, on March 10th, 2010 I post someone else’s. Came across this series in a PZ Myers lecture, pretty entertaining and you should go check out Mr. Deity yourself.
