Most of studies in ecology are observational not experimental.
Perhaps, perhaps not. Depends on who you ask. The point is really moot - if
your system is amenable to manipulation, a proper experiment is invaluable.
Most field ecologists are dealing with systems that are not easily
Popper changed his view about evolutionary theory a little later in his long
career. He also noted that the course of scientific theory is like Darwinian
evolution: mutations (theories) and natural selection.

I think that while learning to study science, the hypothesis testing
format provides a framework in which a student can easily think more
deeply about the topic at hand and avoid presumptions of what will
happen. I agree with your assessmen tof AIC and of ecology in
general. We are all just

Thanks to everyone who responded to my questions about game cameras. I
received some very interesting and enlightening responses!
Ecology without hypotheses has been dismissed (sometimes derided) as natural
history, but even natural history requires one hypothesis. Reporting an
observation requires 0 confidence that an observation is meaningful, can be
communicated, and can be interpreted. There are also tacit hypotheses
Hi Chris and all, I actually think that it's a mistake to diminish the
role of p-values. My opinion on this (stongly influenced by the
writings of Rob Peters) is that there is only one way to demonstrate
understanding and that is through prediction. And predictions only
demonstrate

Hi everyone,
I ran an experiment this fall that tested Chinook salmon survivorship in
artificial redds. The redds were housed in 25 chambers made of 8 PVC tees
and other components that ensured an even delivery of flow throughout the
tee. Water was delivered and regulated by a gravity-feed system

You folks are much better equipped to comment on this.
Have read several articles on the issuesome, where the people involved were
even trying to stave (think it is still a word?) off future and larger
earthquakes. I know some recent movies have used this issue, and usually they
suggest

I wonder if you mean Alpha values?
p-values are what they are and only tell you how likely the
relationship expressed in your statistical test is to be repeated.
The alpha value is an apriori set value used in decision theory. If
you set alpha to 0.05, then you state that if the p /= 0.05bla
