Are There Any Waste Water Treatment Plants Using Algae In The Netherlands?


I’m writing a paper about algae biofuel becoming a realistic option for the Netherlands. Some information seems to be eluding me whether I search online or in journals. I can’t really find any information about waste treatment plants in NL using algae.. information about what they are called, where they are located, which reactor is used, anything about the cost involved , how much biofuel is/could be expected to be produced from a municipal waste water, or the products made from the biomass..biofuel or niche markets and such..
Some other questions I need help with would be;
1)would omega bags work in Zeeland or Ijsselmeer, is there enough sunlight in NL for that to be realistic?
2)How much fuel does the Netherlands use in one year?
3)If algae biofuel were to make a significant impact in Dutch fuel use (replace a certain amount of fossil fuel) how many liters would be needed?
4)How many ha would be needed in NL to fill that requirement?
Thanks!

Role Of Sympatric Speciation In Animal Evolution?


Hi guys
I’m currently working on an essay titled “The Role of Sympatric Speciation in Animal Evolution”
I’ve currently mentioned a few points on habitat differentiation (niche differentiation => temporal isolation => sub-population becoming reproductively isolated => new species)
I’m going to mention polyploidy (however it is insanely more common in plants than animals. Find it difficult to find examples of polyploidy in animals.)
I’m going to mention habitual differentiation (how females will can be very selective of their mates, i.e only go for a certain colour etc.)
Can you guys think of anything else which would fit in nicely? I’m struggling to find examples of sympatric speciation, and I think I’m struggling to find examples of sympatric speciation and not just speciation.
Thanks!
Blue!

What Is An Example Of A Niche In A Pond/freshwater Ecosystem?


In a pond, there are so many different places…
There are niches right at the water’s edge.
There are different ones, just a few feet deeper into the water.
Then there are other niches very deep in the water, and others deep in the soil at the bottom of the pond.
There are niches associated with algae growing underwater and others growing on plants floating in the water.
There could be shady parts of the pond vs sunnier parts, where organisms that prefer one or the other prefer to grow.
If the pond is large enough, it might have an island, effecting creating a barrier from the rest of the shoreline and possibly a very specialized niche…
