4. explain the methods at a level that provides a concrete picture of what the authors spent their time doing, and also gives a sense of where the data come from, or what the variables are.

5. explain the major finding in a way that connects with the main question or hypothesis, and,

6. identify the contribution that this article makes to the scientific context in which it is embedded.

Explanation / Answer

2. In this article the authors are questioning that the predictions of phenology based only in isolated events, like first date of flowering of one species, are accurate, they want to use a bigger database that gives us a more global information of this phenomena.

3. the main question is if we use a database of 60 species that were present on the last 50 years, instead of fewer species, in a shorter amount of time,and with the measurement of only the first date of flowering: are we going to find different patterns of phenology than studies with smaller amount of data and this way find a major magnitude of shifts in the timing of flowering?

4. They used a database from the Rocky Mountain Biological Laboratory. They measure the number of flowers, the number of influorescences, the annual rate of flowering and they also calculate co-flowering between species to find patterns of flowering and community level annual phenology.

5. The answer to the hypothesis is that as predicted, the patterns are a lot more complex when all this data is considered and not just the phenological firsts, that there are independent shifts between species in first, peak and last flowering and that there is a great amount of phenological changes through time in individual species.

6. The main contribution to ecology is the importance of studying phenology as a whole: throughout time, between species and throughout the whole process of flowering and not just the beginning.
