Can't draw any conclusions from that. Data is only as good as study design, sample size, statistical methods used in analysis of data. Who published the results and what journal it was published in....
That's a good start, Jm. Of course, we could be a bit more specific about the criterion, unless it's to our advantage to be vague. I'd hope it applies to both sides of a discussion.
With wildlife competing for less habitat, I'd wonder also if any species that're on an upswing have done so to the disadvantage of others. I'd also wonder about things like rooting animals such as feral pigs in some areas that weren't around in appreciable numbers at times in the past.
