Links: Plants Send for Help and Changing El Ninos

Tobacco Hornworm Caterpillar (A. Williams)
To start off today, we have a cool story that outlines one example of an evolutionary arms race. We usually see examples of predator/prey races, but it occurs in herbivore/plant interactions as well! Tobacco plants calling predatory insects to their aid when being eaten by caterpillars? If that isn't an extremely cool instance to evolutionary warfare, I don't know what is!

Plants send SOS signal to insects.

One of the worrisome unknowns about climate change is the effect on the Earth's oceans. We've been able to predict what we think might happen, rising sea levels, changes in currents and temperatures, etc., but until it happens, it's hard to tell what will actually occur. Well, it's happening, so the data is starting to come in. NASA (National Aeronautics and Space Administration) and NOAA (National Oceanic and Atmospheric Administration) have teamed up to study the effect of climate change on El Ninos. The findings show effects, of course, but what these effects mean for those that are influenced by the phenomenon aren't known yet.

El Ninos are growing stronger, NASA/NOAA study finds.

  1. color echoes in consciousness. the thing moves, but in time slices, not really, but stationary, no problem. I like the nice square size, because... no problem. the.l
    now you know, and you can fite have the battel.
