Raws li kuv paub hais tias koj twb pom tej yam uas tau ntsiag to awfully ncig tuaj txog ob lub hlis tas los no. Feem ntau lub ib hlis ntuj kuv tau tes koj tawm, ntawm San Francisco rau Chicago. Tu lub foundation uas txhawb kuv ua hauj lwm rau lub xeev California Academy of Sciences muaj tej tawv nyiaj hu ua thiab kuv txoj hauj lwm yog sis txiav. Ntxiv no ntawm cov CAS tsuas meant muaj tsis muaj txoj kev rau kuv nyob rau lub tsev khaws puav pheej – xws li yog cov tshawb nrhiav nyiaj txiag ephemeral ntiaj teb no. Kuv mam li nco tus phooj ywg amazing uas kuv muab thiab qhov zoo nkauj California toj roob hauv pes, plaub lub xyoos meej flies uas nyob rau hauv ib lub eeb. Tsis muaj ib tug tsis ntseeg kuv mam li nrhiav tau ib yam dab tsi tsis dhau distant yav tom ntej (Yog koj paub tej yam qhia rau kuv paub!). Hauv lub meantime kuv yuav tsom rua xyaum nrog kuv Diam duab iav thiab tau cov thawj ua uas tau raug dai deb dhau lawm ntev.

Caij nplooj ntoos hlav/cua daj cua dub caij yog ze kaum ntawm no nyob rau hauv Chicagoland thiab kuv xav hais tias nws muaj kev ruaj ntseg hais scenes li no tseem yog ib tug tshaj plaws ntawm cov nqi. Nyob rau ubno tuned, neej tshiab, thiab uas kuv yuav tsum tsiv mus nyob tom ntej!

Lub teb chaws npauj lub limtiam 2012

Tus thawj xyoo Lub teb chaws npauj lub limtiam yuav muab qhov no lub caij ntuj sov, July 23-29, 2012! Qhov no yog cov kev tshwm sim thawj thiaj nyob hauv Teb Chaws Asmeskas (tias nrov nyob rau hauv cov UK kuj yog ib zaug) thiab yog ib tug los qhia kom neeg taub hau rau sab nraud thiab tshawb lawv cov fauna ntau overlooked npauj. Teb Chaws Asmeskas muaj ntau haiv impressive npauj nrog nyob 11,000 muab piav txhij txhua hom, feem ntau ntawm uas neeg tsis tau npe ob tug. Ua ib tug pej xeem yog ib kev kawm qhov yuav muaj nrog tus neeg uas xa tawm cov ntaub ntawv (duab los yog lub npe) ntawm npaub nyob rau hauv tej thoob lub teb chaws. Yog koj nyeem no blog koj tej zaum muaj txaus txaus siab koom! No daim ntawv qhia teev sijhawm uas tseem tab tom sau npe – muaj ib yam ntawm koj thaj chaw? Hu rau tus neeg ntawd tau thiab koom tau rau hauv! Kuj muaj ntau ntau ntawm kev teev koj cov kev tshwm sim. Kuv mam li mus sau npe rau ob peb hlis thaum twg kuv paub tseeb qhov twg kuv mam li muab, tiam sis koj yuav suav tau rau hauv nws qab BYOB (npias yog ib daim teb zoo mov).

Coincidentally hauv lub limtiam npauj hnov nrog cov Lepidopterists’ Haiv neeg los sib tham yog li no xyoo nyob Denver, Colorado. Lawm, sawv daws yuav tsum taws tawm thaum hmo ntuj mus nrhiav npaub. Yog hais tias koj nyob Denver thiab xav pom nws yog peb tsis, thov mus tuav ib txog kuv, Kuv yuav zaum tau tuaj koom lub rooj sab laj no xyoo.

Pov npav rau Shark kev txuag!

Koj txog haujlwm network blogger David Shiffman nyob hauv lub laps kawg ntawm ib $10,000 ntawv sib tw. Cov nyiaj yuav tsis tsuas yug tus David blogging nyob rau yav qab teb Fried Science, tab sis yuav tau tshawb fawb shark kev txuag (nrog rau ib tug contest mus rau npe rau shark nws yuav tag nrog rau cov nyiaj txiag). Mus ib pliag thiab pov npav rau nws, Thaum txhua 24 teev! Nws yog tam sim no nyob hauv cov hlau lead uas muaj ib tug dlej %3 paj tau paj, Peb cia nws ua li ntawd mas.

Tus npauj npaim tooj liab hauv Disguise

Rau cov intents thiab purposes no zoo li ib tug npauj npaim xiav (raws li nyob rau hauv subfamily Polyommatinae)… heev heev, xiav tom qab tag nrho. Tab sis cov kev xav raws li xim yuav ua rau koj sibtsoo lawm; thaum nws puv no npauj npaim no yeej yog ib hom tooj liab. Yog hloov maj mam sib txawv hauv koojtis zoo lawm thiab ntshe venation, tiam sis thaum kuv xub pom cov butterflies kuv assumed lawv muaj ib hom kev ncua Plebejus icarioides (uas tau tseem ya hauv no qhov chaw nyob rau hauv toj siab Kaibab). Tab sis, ces kuv pib pom cov poj niam butterflies (hauv qab) interacting nrog cov kev nyuaj siab vim thiab ces nws dawned rau kuv – tooj xiav – Lycaena heteronea austin (Lycaenidae: Lycaeninae)!

Cov subspecies no tau muas thaum chiv thawj nyob hauv 1998 yog lub caij, yawm suab George T. Austin raws li L L. heteronea rutila. Tiv thaiv kab mob ntawd tiam sis rutila = los rutilus, nws tau tom qab txiav rutila yog tsis tau thiab tus subspecies lub npe yog hloov mus austin ntawm yawm ntawm George.

Yoov rau hauv Reno: ESA 2011

Kuv twb cia li rov qab los ntawm lub xyoo Entomological Society of America sib tham nyob hauv Reno, Nevada! Nws yog ib lub rooj sab laj ntau tshaj thiaj nyob hauv lub ntiaj teb, nrog nyob 4,000 attendees ntawm tag nrho cov mus taug kev kab tshawb nrhiav lub neej. Kuv nyiam nyob hauv lub systematics no, evolution thiab biodiversity hais lus – Kuv mam li sim mus recap rau ob peb tug cov lus nthuav xov fascinating kuv kawm lawm ob peb lub asthiv tom ntej.

Kev ceeb toom xyov yog lub chaw hais lus muab los ntawm cov kab acclaimed blogger, Tiam sis tus ntxhais! Yog zoo mus ntsib nws kiag thiab hnov txog nws tus kheej yaam puab paub ua ib blogger. Kuv xav kom koj saib tau cov cua ntsawj ntshab ntawm nws hais lus muaj koj tus kheej, Yog hais tias koj twb tsis!

zoo siab koj lub hnub yug, Carl Sagan.

Peb yuav tsum tau tag nrho cov nquam paj nquam nruas no ib hnub nrog ib tsab cai kev kawm los yog skepticism. Cog lub noob rau kev nug thiab kev xaav, los yog muab lub caij rau broaden tus kheej horizons. Yog kev ua ntej yuav kaj ntug no sawv ntxov thiab saib cov hnub qub ploj qab ntawm lub tshav microscopic kaj thaum sawv ntxov. Nws coj mus mloog kuv kawm ntawv qib qis kawm kev kawm thiab cov scratchy VHS recordings ntawm peb pheej saib Cosmos.

Diversification ntawm npaub nrog cov hniav

ResearchBlogging.orgYog txhua leej txhua tus yuav paub tus txheem qauv rau ib tug npauj los yog npauj npaim – zoo li tej khaub plev kom mus zoo raws cov kua paj ntoo nws nkaum hauv paj. Feem coob ntawm cov Lepidoptera muaj diversified alongside cov tawg angiosperm hlav, cov feem miv thiab ntau txog lub neej nyob rau ntiaj teb ib qhov. No paradigm tiam sis tsis muaj feem xyuam rau cov Micropterigidae, uas sawv cev tsis tas cov feem basal lineage ntawm cov Lepidoptera, tiam sis yog ib tug ntawm peb tsev neeg uas tau khaws cia mandibles kev sib tsoo paj ntoos los yog tej noob kab mob thiab khi bryophytes, ntau cov plhaws los yog ho nphav kiag li ib cov menyuam kab txoj party. Cov kev xav ua raws li cov pab pawg no ntau haiv tau raws lub hnub nyoog loj heev ntawm tus lineage (110 lab lub xyoo) thiab ib buildup ntawm ancient genera. A tsis ntev los no tus ntawv hom Japanese cov Micropterigidae Yume Imada thiab nws lug txhawb cov miv nyob Kyoto University muab pov thawj mus cuag thiab siv molecular sim lub hypothesis ntawm allopatric speciation tsis muaj niche ua haujlwm rua kev.

Tus sau phau ntawv mus rau 46 localities hla tus Japanese archipelago thiab sau tag nrho 16 paub tias hom twg, ob peb hom tshiab, thiab ib tug genus tshiab heev tejzaum nws. Nrhiav cov npaub rau cov qus yog tsis nyuaj ntawd xwb yog koj paub tias yuav ua li cas thiaj nrhiav tau lub vaj tsev thiab ua licas thiaj tsis lov tawm pob zeb nplua; tab sis thaum koj pom tias qhov nqaij ntawd lub npaub kuj yog pab. Micropterigidae muaj unsurprisingly txuam nrog lawv bryophytes, uas tshwm sim hauv noo yeej raws ntws thiab dej ntws. Qhov tsw xwm ntawm ib pliag thiab qeeb tsiv tsiaj hauv twb raug rho tawm lends xwb los allopatric speciation. Muaj ntau lub microlepidoptera ya NW nyuam qhuav off of cov tswv tsev cog thiab txawm tias lawv yeej ua li lawv tsis paub tias mus ntev distance dispersal. Thaum uas feem ntau cov genera thiab hom yog kiag li cais nyob rau Nyiajpoom teb muaj ntau zaus ob peb qhov chaw uas cov genus Paramartyria tshwm sim li ntawm coob txog Issikiomartyria. Thaum tseem tsis paub precisely li cas cov hom yuav partition lawv cov kev pab ntawd nws yog mas tej zaum yuav sib txawv nyob hauv koj lub neej mus temporal. Ntawm no nyob rau hauv xeev California muaj yog ib ruam tag vastly complex ntawm Apodemia butterflies comprise ib handful ntawm hom thiab (tau mas) subspecies uas yog partitioned rau tib tsob zaub thaum lub caij nplooj ntoos hlav thiab nplooj ntoos zeeg yuav nteg qe caij.

Impressively, txhua micropterigid sau raws li cov tau nyob rau lub Conocephalum conicum hom liverwort, tis ntawd tau kaum plaub txog lwm bryophyte hom muaj nyob hauv tus vaj tsev tib. Nws twb raug ntev to taub tias cov neeg Esxias Micropterigidae tej yam ua kua rau liverworts, tab sis, raws li qhov lawv party things twb yeej tsis tau quantified. Pub tus cwj pwm zoo nkaus li ib yam yuav hla tas nrho cov hom surveyed, cov kab lia grazing nyob rau saum lub bryophytes haus cov khaubncaws sab nraud povtseg nqaij sab sauv.

Phylogenetic tsom ntawm qhov COI, 18S thiab noob EF-1α generated mas zoo tib yam ntoo uas siv ntau txoj kev analytical. Nws zoo nkaus li uas lub teb Japanese genera thiab cov Conocephalum txaus siab monophyletic clade noj daim ntawv uas zoo li tus dej (hauv ntsuab). Hauv ntej, tawg rau ntawm tus tswv tsev qhia tseeb Micropterigidae coincide nrog rau kev sib cais, uplift, thiab cov kev rho tawm ntawm tus Japanese landmass roughly 20 lab lub xyoo dhau los. Nws yuav tsis tau yooj yim tshaj tawm tias tus Japanese Micropterigidae rau ntau haiv yuav tsuas yog li qub yog tias koj yog nws tus kheej lub hypothesis; thiab nws tseem yog ib lees Disease fact niaj hnub ntawd allopatric speciation muaj ntau feem dua ib zaug xav. Tiamsis quantifying no theories thiab piav li cas thiab vim li cas thiaj zoo li no yog raws nraim li cas cov kev kawm uas yog hais txog.

Tus ntawd yog li cas tus hais tias huas, txoj cai? Ob lub lis piam dhau los kuv Vej 5th txhua xyoo National Geographic BioBlitz dhau hauv Saguaro National Park nyob Tucson, Arizona. Nws yog ib tug yawm keb kom tau rov qab mus ua teb thiab yog thawj zaug kuv sau Arizona nyob rau lub caij nplooj zeeg. Temps twb tseem thawb rau lub mid 90, tiam sis tej yam uas yuav tsum tau qhuav thiab cov abundance uas caij monsoon impressive ploj mus ntev heev. Nyob rau hauv tag nrho kuv npauj lug txhawb cov miv thiab kuv sau ib ncig 140 hom Lepidoptera, 56 cov uas tau microleps! Sadly ho muab nkawd tias cov miv ob kab ib tug nyob deb thiab ob peb inbetween, los yog lwm yam kev paab entomology tsis ua tib zoo tally txhua yam lawv pom. Tsuas 190 raws tau suav nyob rau hauv tag nrho – peb poob rau vascular nroj tsuag (325 hom) thiab txawm hu ua fungi (205)!

 

Ntawm no yog ib tug Thaum luv luv nrog kuv ua ib tiag tiag tsev pheebsuab kub nrog cov me nyuam kom ntau (leej twg yuav tsum tau muab kuv no no kuv tam sim no muaj). Saib tsam kuv qus kwv yees uas tus tau 15,000 hom hauv Teb Chaws Asmeskas no rau cov ntshav sab, tab sis nws tsis yog tsis yooj yim sua.
