The 2011 Philippine Biodiversity Expedition

Banahaw summit  Tropical mountains are like islands, harboring a cool-adapted flora and fauna that is typically very different from that of the surrounding hot lowlands but may be similar to other mountaintops far away.  Most of the early part of my career was spent studying the spiders of mountain islands in Africa, and my discoveries suggest that for spiders Africa’s mountain islands are very old, with their last connections severed long before the Pleistocene, i.e., more than 5 million years ago.  Are Philippine mountain islands equally old, and unique?  The summit of Mt. Banahaw de Lucban is at nearly 1800m, more than 1000m above the base camp.  To study it we must go there, which means hiking.  For me this meant 5 hours of steep, hard climbing, the last 2 hours in pouring rain.  Here Orly and Lando make steady upward progress in the rain and mud.
