What is it about?
Theory suggests that seed predation - consumption of seeds by animals - will decrease with altitude and latitude, but experimental results are contradictory. We assessed predation on a standard set of 32 seeds species along a 2300-meter gradient on a mountain in Myanmar. Unexpectedly, the pattern of predation changed between the dry and wet seasons, suggesting that previous studies on a few seed species at one time of the year may not give reliable results.

Why is it important?
The number of seed species tested, the long gradient, and the repetition in two seasons are novel.
Perspectives
I was not directly involved in this study, but have visited the study sites. The mountain - Mount Victoria in English, Nat Ma Taung in Burmese, and something else in Chin - is an amazing place and well worth a visit.
