לקליפורניה אלה קריאה, במיוחד אלה בדרום, לפקוח עין לעכביש קטן זה יפה, Latrodectus geometricus – האלמנה החומה. Arachnologists באוניברסיטת קליפורניה בריברסייד עוקבים ההתפשטות של מינים פולשים זה. באופן אירוני מתברר שלא יהיה מסוכן כמו האלמנה השחורה האם שלנו. אף על פי כן, זה לא מכאן בסביבה אלה חלקים (יש אמר במבטא הדרומי הכי טוב שלך). אם אתה מוצא את דגימה, במיוחד אם אתה לא בלוס אנג'לס / כתום / מחוזות SD, אתה צריך קשר צוות בUCR. שתף את זה!עם קוריאה על הסף של מלחמה חמה, אסון אקולוגי חסרת תקדים ופרופורצית התסיסה האזרחית בג'מייקה (מישהו harshed הרך שלהם) – רק שם כמה מכותרות של היום ממקורות אחרים – CNN לוקח את הזמן כדי לנפח את עמודו הראשון.
I usually get a little excited when I come across articles like this because I always have hopes for something so ridiculous it has to be discussed. Thankfully CNN is run by teams of drunken marmosets who like to fling crap at us. Before the Skeptical Moth epoch I would share links to cover page stories on the findings of bigfoot, chupacabra and aliens with just a few friends or spread it around facebook. Now I can ridicule CNN on a google archived medium. I just do not understand the point of this article. John Blake doesn’t discuss an explanation for this phenomenon, offer an opinion, or ask any questions. בטוח, he asks if God really cares who wins, but that question isn’t any more valid than asking if my dog (also fictional) cares what kind of car I drive (unless of course it is psychic! Seriously…people believe this). When I read articles like this I feel as if I am grading papers in a high school english class. There is no journalistic integrity, intelligent opinion or factual basis for the scribbling – there are just pretty pictures and words illustrating them. Setting the whole prayer and faith issue aside; athletes have always been known for their superstitions (another). ה “acceptance speech” phenomenon undoubtedly falls under this category. After achieving a statistically small outcome (לראות hot hands), they are afraid of forgetting God in fear of magically losing their ability (not necessarily consciously). For some reason Blake restrains this article to only sports – perhaps he is intentionally playing into the massive demographic of American sports loving, bud-light swilling, christians – but clearly this is a reoccurring theme. At any awards ceremony God, Jesus or Allah is usually at the top of the thank-you list. Forget all that hard work and talent you might have, it was something or someone else. Abandoning all rational thought to a mystical being is a dangerous thing. This mindset is the same one that allows addicts to blame anyone but themselves (even if addiction is in part hard-wired), believe in faith healing, start a holy war, or let the Catholic church blame the devil. CNN is flashing the lights and jingling the keys over the faces of their readers. Usually I leave it up to FOX news to insult my intelligence, but I am glad to know I have a choice in this market. שתף את זה!
פעם אחת במופע לכל החיים, א bilateral gynandromorph. בתמצות, תקלה במהלך התמיינות תאים יוצרת דפוסי כרומוזום סימטריים, מה שמוביל לביטוי מין סימטרי בחרקים הבוגרים. אם לא לחץ על הקישור, לעשות זאת, זה תיאור מעולה עם כמה תמונות מדהימה. חזור לפרפר. I was in the field this March just above the middle fork of the American River on the hunt for Xanthothrix, with me was Brian Hansen and Bob Patterson. Bob and I were on a mission, to locate a remote patch of Coreopsis high on serpentine soils, and to find our rare little moth. Brian came along to enjoy the day and explore the butterfly fauna. While Bob and I hiked ahead anxious to see if the days hike would be worth it, Brian stopped frequently to net passing leps. It was probably less than an hour out from the car when we hear form behind us on the trail “Hey guys… I think I just caught a gynandromorph!!!” אישור, I was skeptical. Bob and I approached to see Brian holding a little blue in his hand, which unmistakably, was a bilateral gynandromorph. I was blown away. Bob has over 50 years of experience as an avid lepidopterist and has never seen one of these in the wild. To make this feat even more impressive, this small blue butterfly is one of the commonest insects in the American west in the spring. היום, they were puddling in great numbers along the trail, and I hadn’t even stopped to blink at one. Brian just netted a one in a million catch. Perhaps it is the curse of a jaded lepidopterist that will keep me from such once in a lifetime discovery; but I know I will be looking closer at even the commonest butterfly as it wings by me. So as you can see the butterfly is exactly half male and half female (the right side is female). If you look very closely you can even see a perfect vertical line bisecting the body if the insect (looks like a photoshop edit almost), gynandromorphism after-all is expressed throughout the entire body and even the genitalia are contorted into strange shapes. The specimen is in Brian Hansen’s personal collection, and you can find the images hosted on the Butterflies of America website.

כמובן, it was named Phallus drewsii. This comes form the list of the top 10 species named ב 2009, נענה על ידי אוניברסיטת אריזונה (אינה רשימה טובה מאוד אם 7 של המינים החדשים שלי לא היו שם…). While I tend to avoid phallic and O’Keeffesque botany, this one I couldn’t resist because it was named after someone from my own institution. ד"ר. Robert Drewes now has a small phallic fungi named after him (with permission). Taxonomy humor at work. שתף את זה!
Has just been posted over at חיפושיות בבוש. Go over and explore the latest moth carnival, a gathering of blogs that have featured moths in one way or another over the last month or so. שתף את זה!News in from India, a butterfly photographer has been kidnapped. A local park official who was visiting the north eastern province Arunachal Pradesh was taken at night by a gang of armed youth-rebels. Efforts to find him have been hampered by the weather and remote terrain. India has recently become one of the most difficult countries to conduct research in, and now we are all reminded of its continuing history of violence. Often it is within the remote and wild portions of a developing country that harbors both stunning biodiversity and militant dissidents. While in Ecuador my group kept an eye out for Columbian FARC rebels who may have strayed across the border; thankfully it was only a minute possibility they would be there in the first place, and nothing was seen. I think some of my most harrowing field work has been along the US-Mexican boarder states and in Mexico itself. Drug runners would rather shoot you before asking you to move out of their way, and roaming banditos were responsible for a murder of a colleagues friend in Oaxaca years ago. לא מפתיע, the lure of untapped biodiversity keeps pulling us in. Stay safe in the field! שתף את זה!Over a long weekend I’ll be out in the field. Stay tuned for incredible stories (no hype here…). While I’m away enjoy the following from other excellent bloggers:

למי שאינם מודעים, ספר חדש להכות את השוק בסוף השנה שעברה. “עשים של מערב צפון אמריקה“, פאוול וOpler. רק ב $95 זה שווה כל אגורה (או $75 לספר האלקטרוני, אבל אני שונא את הספרים אלקטרוניים). It’s a remarkable tome and the first of its kind for the western states. Not only is it a spectacular reference, but it sets the bar for all insect books. לא, not every moth in the west is in there (that would break my desk and wallet at over 6,000 מינים), but almost one of every genus and common or remarkable species has a photograph, life history and distribution. Most importantly it covers microlepidoptera. I grew up on the eastern counterpart, Moths of Eastern North America by Covell. I had two copies, one for the field and one for my desk – and had to replace the field copy at least once. It was a great book, but Powell and Opler have run laps around it. The other good news is you can now access all 1,228 moth illustrations and corresponding data online for חינם. Go to CalPhotos and search for Powell, או click here. The nice part about this is the somewhat smaller microlep photos in the book are available in high-resolution for better identification. Beautiful addition to the reference and easier than sending everyone a CD. שתף את זה! |
