You see, diversity is good for you . . . .

Woolly mammoths may have died off because of lack of genetic diversity, rendering them susceptible to disease and climate change. . . .

Rabbit sexual harrassment

Yesterday evening, I saw two rabbits in our backyard, which is not uncommon in the spring.  How sweet, I thought, they're playing together.

I was filling the tub for my son's bath, so I had some time to relax and watch the rabbits.  One of the rabbits kept sneaking up from behind on the other one, sniffing the other one's butt, and then . . . was it trying to mount the other rabbit?

The second rabbit did not appreciate these advances, and spun around quickly.  The first rabbit actually stood up briefly on his back legs in a defensive posture.  The second rabbit then moved away and started nibbling on grass.  The first rabbit again crept up and attempted to engage in the same behavior as before, prompting the same reaction from the second rabbit.

I started wondering, do rabbits engage in sexual harrassment?

Random question of the day

This question actually came up in a conversation I had with a colleague (I asked the question):

If you had to choose one or the other, would you rather eat a ratburger or an insectburger?

Surprisingly, that colleague and another one that I polled had trouble deciding.  Maybe it's just me, but I'd think it's a really easy choice -- rats are still mammals, not too different from rabbits (which I've eaten once before), whereas insects are bugs (ick!).

Call me a speciest if you must . . . .

If we could eliminate insects from the world without messing up the food chain, I'd be all for it.  But it appears that the Endangered Species Act doesn't just protect charismatic mammals like elephants and bears and lions, but also picture-wing flies:

Picture-wing flies are about two to three times the size of common house flies and are considered harmless to humans. Other species of picture-wing flies are found outside Hawaii.

The flies are named for the intricate markings on their clear wings and are known for their elaborate performances when protecting their territory or courting a mate.

Two to three times the size of common house flies?!?  Yuck!

"Kill the wabbit, kill the wabbit. . . ."

While raking leaves this afternoon, I noticed a dead rabbit in our backyard.  I didn't get very close, but it didn't seem to have suffered any fatal wounds, so perhaps it died of old age, disease, or internal trauma.  In any event, is it a biohazard?  Do I just bag it up and dispose of it with the trash?  Or do I call Animal Control or some such equivalent city department?

See wildlife in Botswana!

Is it okay to feed these zoo animals?

The London Zoo has a new species on display . . . homo sapiens:

The scantily-clad volunteers will be treated as animals and kept amused at the central London zoo with games and music.

Bringing elephants home?

I used to joke about this, but apparently some scientists are serious about a proposal to repopulate North America with large African mammals:

The scientists say that not only could large tracts of North America act as breeding sanctuaries for species of large wild animals under threat in Africa and Asia, but that such ecological history parks could be major tourist attractions.

"Africa and parts of Asia are now the only places where megafauna are relatively intact, and the loss of many of these species within this century seems likely," the team, led by Josh Donlan from New York's Cornell University, said.

"Given this risk of further extinction, re-wilding of North American sites carries global conservation implications," the team wrote in Wednesday's issue of the science journal Nature.

Maybe some of the Asian mammals can live in that stupid Coralville indoor rainforest project. . . .

I'm not going to complain about sleep deprivation anymore

Not after reading about what dolphin and killer whale parents go through:

Sleep-deprived mothers of newborn babies should spare a thought for bottlenose dolphins and killer whales.

A study has shown the young of those two species do not sleep at all during the first month of life. They are active 24 hours a day -- and their mothers have learned to cope.

That's just scary.  Though I note that the study concludes that the "mothers" have learned to adapt.  Does that mean that dolphin and killer whale dads don't share equally in the raising of the little ones?

Exhausted

I've just had 7 hours of committee or faculty meetings in the last 29 hours.  I'm too wiped out to blog about much, but here are some quick links:

- Judge tosses Lynndie England's plea: This isn't meant to be any defense of England if she did what she is accused of doing (and what the pictures seem to substantiate), but I noticed that an earlier version of this story had a picture of her with her baby.  The plea, had it been accepted, would have capped her sentence at something less than 11 years, but the cap was secret.  Still, presumably there was some significant prison time involved.  I can't imagine being kept from my little guy for any amount of time like that. . . .  What a true punishment, if she's convicted in her court-martial.

- My son the tease: My baby son has a new trick where he extends his finger food like he's going to give it to me, actually touches my palm, and then quickly takes the food back, smiles and chortles, and then eats it.  Where do babies learn things like this?

- "American Idol," what's wrong?: Ann Althouse has it right; this is the worst season of "American Idol."  It's been too many weeks of boring songs sung boringly to be anything but the fault of the performers.  They're not bad, but they just aren't good the way that Kelly, or Fantasia, or even Clay and Reuben were.

- "24": still loving the ending of the last episode.

- Kevin Brown looks done as a major league pitcher.  I had drafted him in the 14th round of my fantasy baseball league, but I cautiously kept him on the bench until he showed me something.  All he showed me was that he was throwing batting practice in the first inning of his starts.  I cut him even before yesterday's debacle and added Erik Bedard of the Orioles.  At least Brown didn't cost me anything other than the opportunity cost of whoever I could've picked and the roster spot; I didn't get saddled with any of his outings.

UPDATE: Another random thought:

- Why is it never charismatic mammals thought to be extinct that are rediscovered?  Instead, it's three species of snails. . . .
