อุ่ย, ดูเหมือนว่าฉันพลาด 'blogoversary' ครั้งแรกของฉัน! จันทร์ที่ 21 เป็นจุดเปลี่ยนหนึ่งปีสำหรับบล็อกของฉัน; และผมมีความสุขอย่างไม่น่าเชื่อว่าจะมีการใช้จ่ายปีที่ผ่านมาใช้งานร่วมกันบางส่วนของเรื่องเล่าของฉันกับทุกท่าน. I’ve somewhat lost track of how many hits I’ve had since I moved everything over to The Southern Fried Science Network, but it’s more than I ever could have ever imagined as a newbie blogger twelve months ago. When I look over the last year a few posts come to mind as my favorite:
Shockingly, stunningly, amazingly; themonarchs are back (but not co-staring Julianne Moore). ตกลง, it’s not that amazing; I pretty much predictedthis would be the case last March when everyone was running around terrified because the butterflies hit an all time low (since counting startedใน 1993). Actually I believe I said “ฉันจะเดิมพันทุกอย่างกับประชากรที่กำลังฟื้นตัวในปีต่อ ๆ ไป…”. ดังนั้น, how about anything = beer, and who’s buying?
Perhaps I am celebrating a bit early. Maybe the news isn’t so good that I can run a victory lap quite yet, but preliminary surveys look like the overwintering populations have doubled this year. That’s a pretty good start, but we still haven’t hit the 18 year average (not an impressive statistic). But don’t misread my intentions – I’m not claiming this one year somehow has proven the decline insignificant. It may or may not be, all we can really say is that it’s just another data point. The fact is that our dataset is very weak and there are factors such as local weather that create massive margins of error. It’s also nearly impossible to extrapolate from what little data we do have. So is the monarch a very good “canary in the coal mine”?
I would say poor at best. How is one insect species that roosts in massive singular colonies a good indicator of our ecosystem? ใช่, they migrate from all reaches of North America, but their recent high mortality rates have nothing to do with the lives they lived outside of Mexico. Perhaps if millions of butterflies died of some strange toxin we could heed the warning, but such was not the case. Those poor monarchs are at the mercy of winter storms that are likely to become more frequent with a warming climate. So can we say that climate change is negatively impacting these animals? Turns out we can’t, at least not yet. If this were to be so then our data is telling us that the1996-1997 seasonwas a really healthy one where clouds of pollution parted and nature rejoiced. Did the 2010 season then become a post apocalyptic blade-runner-esque world where acid rain melted the orange off of butterfly wings? Clearly not. Neither climate nor pollution were drastically different in those years. The monarchs just had a really good year followed by some really bad ones. Maybe we should just find a better canary if we’re trying to blow the whistle on global warming or deforestation.
As a last thought here is a video from the above story. Just as you’d expect, it’s over dramatized and a bit hilarious.
A softball for this GOP challenge. This image comes care of the Victoria Advocate (TX paper) – กับ poorly written article about butterflies. This image flop is pretty easy, but for extra points who can tell me what else is incorrect in the text?
I’ve uploaded a new header as you can see – how does it look? I’m playing around with the settings, but please let me know if the moth on the right gets cropped awkwardly, and what your screen resolution is if that is the case.
หากคุณอาศัยอยู่ใน Yolo, เทศมณฑลโซลาโนหรือแซคราเมนโตที่คุณควรมุ่งหน้าออกไปด้วยเน็ต. ดร.. Art Shaprio has offered for the 40th year hiscabbage white butterfly competition. ถ้าคุณเป็นคนแรกที่จับกะหล่ำปลีขาว (Pieris ออก – invasive) before Dr. Shapiro he will buy you a pitcher of beer! You have to deliver the specimenaliveto the receptionist in the Department of Evolution and Ecology to confirm the identification (I assume to prove you didn’t just save last year’s dead butterfly and cheat).
Over the last 30 years the butterflies have been emerging earlier – two weeks on average now. You better hurry, the first cabbage white of 2010 was collected on January 27th.
For this issue of the genius of the press, who can tell me what’s wrong withบทความนี้? It’s pretty subtle, but a clear mistake, especially for LiveScience.
