"General Ecology"

Post by GraciousRandomness » October 29th, 2020, 2:29 pm

On the instructions, it asks for the "general ecology" of many species. What do I need to know to have the "general ecology" of a species? Location? Breeding Habits? Appearance? Any suggestions are helpful!

"General Ecology" would refer to anatomy and physiology, distribution, ecological role/niche, life cycle, and feeding habits. You might also be asked about important facts associated with those organisms, such as major outbreaks of Crown of Thorns starfish happening in the Great Barrier Reef.

All of what you and scuffed listed; also any cool facts about the organism. I wouldn't worry too much about researching "general ecology" in particular; rather, just google the organism and try to learn interesting things about it. Ecology is the study of how organisms interact with other organisms and their environment, so any time you see information about how it changes its own ecosystem (sometimes with many far-reaching effects), how its own adaptations allow it to survive in its environment, and how it interacts with other animals, that's ecology! Diet and life cycle are included in these.

Make sure you are familiar with overall ecological concepts so you can apply them to specific organisms and interactions; also get things like whether it's diurnal or nocturnal, or where it lives or what its mating system is.

WQ is a really fun event, and hope you enjoy it!

Hi, I was wondering how would you be able to derive the seasons and latitudes from looking at the cline curves. I saw in a test it showed me this image:

and asked what the season was and what latitude this graph was taken at. So their answer was summer and 60-80N. But how would you be able to derive this and how would it look in different seasons and latitudes?

Thermocline is deepest in the summer because stronger winds cause more mixing, while the lower latitude you are, the more steep the thermocline is (this is because warmer temps nearer the equator cause higher surface temperature, while the temp of the water at the bottom is mostly the same everywhere.
13 degrees Celsius is pretty cold, so it must be near the poles (60-80 degrees). I don't think you can tell which hemisphere it's in, though. To get an idea of what the thermocline looks like in each season, go on google and compare the images.

Hope it helped!

EDIT: oops, I think I messed up the justification for summer. In the poles, pycnocline is mostly determined by salinity because surface water is so cold it's not much warmer than the bottom water. In summer, the surface heats up slightly, so in summer the thermocline is both deeper and crossing a greater temperature gap.
