What are some topics or questions that undergraduates or post-baccalaureates would have when they are considering applying to graduate school, particularly in the fields of biology, ecology, natural resources, or related fields in the US or Canada? Are there any publications, websites, blogs, or other resources that provide valuable discussions of such topics or at least a list of possible considerations? I have encountered many examples of resources for individual, specific considerations (e.g., how to apply for a particular fellowship), but I am looking for a more comprehensive inventory of topics, or better yet a general how-to guide.
Note that this answer was given for an earlier version of the question that asked for topics to cover in a workshop for undergraduates. The question is now very different. It wasn't originally a shopping question.
I have a few suggestions, but not a comprehensive answer. And it is broader than biology.
First, see the answer for the US to this canonical question about doctoral admissions. Note that it doesn't work the same for masters degrees.
In addition to the admissions process, make sure students know they maximize their chances of admission if they cast a broad net, in particular, not focusing only on a small set of "top" schools.
Second, if you want to include Canada, make sure you understand that there are differences and what they are.
Spend some time on explaining, not just the application issues, but the main requirements of obtaining a degree such as (in US) the early advanced coursework, preliminary/comprehensive exams, when to choose a professor and a topic and what to expect to have to do for successful research.
In the above, talk about the funding possibilities such as TA and RA and the time and effort that is required for that.
In the modern age you might have to talk about the progression from doctoral study to a suitable position, including postdocs and such. It isn't trivial.
You might even want to bring up the possibility of such things as burnout and how to find help for that if/when it happens.
