The Philippines in the Chemical Global Value Chain

This report uses the Duke CGGC global value chain (GVC) framework to examine the role of the Philippines in the global chemical industry and identify opportunities for the country to upgrade. The Philippine chemicals sector is growing rapidly alongside economic expansion and a revival in manufacturing. By 2013, the chemicals sector as a whole accounted for 6.7% of GDP. Chemicals exports reached US$2.2 billion in 2014, approximately 3.5% of the country’s export basket. The sector’s expansion has outpaced both global and regional trade; with a compound annual growth rate of 13% since 2007, three times as fast as global exports, and twice as fast as Asian regional exports. Participation in the export market is based primarily on commodity products in the oleochemicals and petrochemicals sub-sectors. Within these segments, exports are driven by a small number of products, with the top 10 accounting for approximately threequarters of all exports. While the country is a small player in the global chemicals trade, accounting for just 0.2% of exports in 2014, it has generally been successful in carving out a presence in these niche products, and is one of the global leaders in most of its top product categories.

Eco-evolutionary trophic dynamics: loss of top predators drives trophic evolution and ecology of prey.

Ecosystems are being altered on a global scale by the extirpation of top predators. The ecological effects of predator removal have been investigated widely; however, predator removal can also change natural selection acting on prey, resulting in contemporary evolution. Here we tested the role of predator removal on the contemporary evolution of trophic traits in prey. We utilized a historical introduction experiment where Trinidadian guppies (Poecilia reticulata) were relocated from a site with predatory fishes to a site lacking predators. To assess the trophic consequences of predator release, we linked individual morphology (cranial, jaw, and body) to foraging performance. Our results show that predator release caused an increase in guppy density and a "sharpening" of guppy trophic traits, which enhanced food consumption rates. Predator release appears to have shifted natural selection away from predator escape ability and towards resource acquisition ability. Related diet and mesocosm studies suggest that this shift enhances the impact of guppies on lower trophic levels in a fashion nuanced by the omnivorous feeding ecology of the species. We conclude that extirpation of top predators may commonly select for enhanced feeding performance in prey, with important cascading consequences for communities and ecosystems.
