Hi Andreas and mastwatchers,


There have been several efforts to study the impact of dipterocarp winged fruit on their distance of dispersal. Bu don't forget that the vast majority rarely fall in a wind, and then only into the main canopy a few metres beneath. So studies of the comparative influence of winged versus winglessness on the fate of the embryo (trapped in the canopy versus dropping through (and then what?), survival, predation etc.) deserves study as well.

Dear all,

This movie was absolutely stunning! We have been working on understanding how the geometry of these flying fruits influence their flight (https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.122.024501<https://urldefense.proofpoint.com/v2/url?u=https-3A__journals.aps.org_prl_abstract_10.1103_PhysRevLett.122.024501&d=DwMGaQ&c=WO-RGvefibhHBZq3fL85hQ&r=QF7wtoDqCqPx93omg7bDZoXToRGpzsmD2pgreRf9a74&m=oEo1ZmDAtLb1DWViFO2kYJvttzDwwUn2NgZs9xNRjkc&s=yRfX3IQEdkRjsXw56pIl9QRoY70NNi19ALjC8c8aeb4&e=>).
Amazing to see this fruiting and fascinating flight!

Thanks for sharing.

Best,
Andreas.

Hi Cam and all,

I just returned from south India and saw some dip fruiting in the forest reserves in Kerala.  Being seasonal forest its perhaps a bit less relevant to the Borneo fruiting - but it would be interesting to link these cycles climatically and genetically at some point!

Cheers
Chris

Thanks all, for the forest news from across Borneo (and beyond).

It seems the Gunung Palung mast was big: definitely biggest since Feb
2010, and maybe bigger than that one. Peak fruit fall was several weeks
ago. Dipterocarp flowering started in late Sept 2018. I¡¯ll post more
details when I know them.

Best,

Cam
