Species impact
 

We'll say humans have impacted the global ecosystem the most.

What species is second?

Although I like the idea otherwise.

This thread may not work.

I couldn't decide if you meant currently or historically, so I was waffling ... and too lazy to look them up.
Besides, I'm not Sklanskalian, I have lots of 31% opinions that I won't bet on.

I'm thinking current and species because otherwise cyanobacteria and algae would take it down.

I also edited my previous post.

Penelope, Purkinje, Kraepelin. and Nala agree with you. I do too, as long as we're talking about the Rduke ecosystem.

It will certainly be a domesticated species. Probably cattle.

This is a really hard question, but I'm going to say E Coli. Aside from its direct impact on many ecosystems and possible role in animal evolution, it's been used by humans to support research and technology that has had a signficant impact on, arguably, everything.

A clear choice didn't pop up for the people having the conversation that inspired this thread. One of the things I was thinking of is not what affects the ecosystem but what prevented humans from affecting the ecosystem. For example, malaria was, and is, really an impediment to developing the kinds of nature obliterating civilization seen outside of the tropics. So one of the Plasmodiums could be a reasonable choice. But then, maybe we just need to consider one of the Anopheles mosquitoes as the species here, since they are the vector.

I still feel like I'm missing something obvious.
