If excel says so, it MUST be true...

The answer:
With density dependent growth models, an experimental population grows till it reaches a carrying capacity of 40 individuals at which time birth and death rates are the same.

What student found:
With density dependent growth models, an experimental population grows till the population size reaches 100000 individuals at which time 70000 die for no particular reason.

At least they are stable...

Students were asked to model population size over time to see at what level population numbers stabilize.

"Our population stabilizes at -0.25 individuals"

So what is that? a quarter of a zombie antelope?

Scary, but true...

An actual conversation that I overheard during a laboratory exercise involving the metabolism of a goldfish between a student (S) and a lecturer (L):


S: Ma'am, we've got a problem...


L: Yes?


S: Well, we're supposed to weigh our goldfish before we start the experiment, right?

L: Yes...

S: Well...we forgot to, so now our experiment is ruined!

L:

S: What should we do?

L: Well, how were you going to weigh the fish before?

S: We were going to weigh a jar of water, put the fish into it, weigh it again and take the difference...

L: So why don't you just do that?

S: What?! You mean we can do that? Even though we were supposed to weigh the fish first?!

L: Well, do you think that the fish is going to lose that much weight during the course of the experiment...?

S: No...

Mosses are small in size and lack vascular tissues. That is why they generally small in size.

Deforestation increases precipitation...?

From an essay on recent floods in China and how these event are related to global climate change...

"Human induced global warming is expected to increase precipitation. This is caused mainly by deforestation that can have a big impact as upland forests can soak up lots of water, but as humans destroy these areas, the water has more land it can run to."


Seriously!? You learn something new everyday.
