Pirmadienis Drugelis

ANSWER: This wasn’t easybut this large and beautiful moth was from Australia and is in the family Xyloryctidae (Philarista sp.). We have a handful of representatives of this group here in the US and Ted MacRae over on Beetles in the Bush has a few great photographs of them. Somehow I think we . . . → Skaityti daugiau: Pirmadienis Drugelis

Chiricahua multidentata (Geometridae)

This Monday’s moth is a spectacular species from the mountains of ArizonaChiricahua multidentata, a Geometrid. The only known location for this species is at the very top of the Chiricahua mountains above 9,000 pėdos (which was just bruned to a crisp). Hopefully the fire was not . . . → Skaityti daugiau: Pirmadienis Drugelis

I’ll keep the ball rolling with Arctiinae and post a photo today of Ctenucha brunnea. This moth can be common in tall grasses along beaches from San Francisco to LAalthough in recent decades the numbers of this moth have been declining with habitat destruction and the invasion of beach grass (Ammophila arenaria). Tačiau . . . → Skaityti daugiau: Pirmadienis Drugelis

Aš ruošiuosi išlaikyti kamuolys valcavimo su šios serijos ir pabandyti padaryti jį labiau įprastas. Aš taip pat sutelkti dėmesį į išryškinti naujas rūšis kiekvieną savaitę nuo masinių kolekcijų čia Kalifornijos mokslų akademijos. Tai turėtų duoti man pakankamai medžiagą… bent kelis šimtus metų.

Richardas Bransonas yra idiotas

 

Šaltinis: Vikipedija

Pasirodo, Richardas Bransonas turi naują idėją; kad išgelbėtų žieduodegį lemūrą (Lemur catta) by importing them to his private British Virgin Island. Kaip nurodoma straipsnyje, Bransonas išleido milijonus svarų ir metų pastangas paversti salą “the most ecologically . . . → Skaityti daugiau: Richardas Bransonas yra idiotas

Paslaptis atskleista

Gerai – a few apologies for not having full images *yet* of the larvae in question (I will in a few days!). Over the weekend I was out with a group of Berkeley students on Mount Hamilton and PhD candidate Meghan Culpepper collected a few species of Scaphinotus and a some larvae! So the specimen . . . → Skaityti daugiau: Paslaptis atskleista

Pasaulinės rūšių įvairovės įverčiai

This recent article in the American Naturalist has taken a second look at some of the famously inflated species estimates, some going high as 100 million (Erwin, 1988). Estimates conducted by the authors indicate that projections above 30 million have probabilities of <0.00001. Their estimated range is more likely to be between 2.5 ir . . . → Skaityti daugiau: Pasaulinės rūšių įvairovės įverčiai

Aquamoth part 3

A continuation of the aquamoth series, this time with video from Science Friday! Taip, I have to link it because wordpress won’t embedThanks Ted, figured it out!

Aquamoth part 2

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 . . . → Skaityti daugiau: Aquamoth part 2

Aquamoth!

Another amazing animal from Hawaiia 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. . . . → Skaityti daugiau: Aquamoth!
