Is it wise to use a Generalized Linear Model (GLM) to investigate trends in abundance over time? Not sure if this would be considered as being a "stupid" question, but I am still very new to statistical analyses. I have population abundance data and I wish to determine whether the trend in abundance (abundance values = counts) over time (time=years) shows an increasing/declining trend. Should (or rather, can) I make use of a GLM to investigate the trend in abundance over time (ie dependent variable = abundance value, independent variable=year (ie time)) ? Or is there perhaps a "better" alternative?
Thanks again :)

I don't know your specific problem, but seem that you can make a model in this fashion:
$$counts = time \beta$$
So if there is significance in your model you can analyze the signal of beta and another stuff.
