Opportunist organisms rafted across the Pacific on plastic

Since World War II, fiberglass and plastic — which are stronger, lighter and require less maintenance than wood — have become the materials of choice for coastal infrastructure like docks. An unforeseen consequence of this transition, however, is that when structures built from these durable materials break free from their moorings and drift out to sea, they can serve as resilient rafts for opportunistic organisms.

Message in a bottle gourd

For about the last 10,000 years, bottle gourds (Lagenaria siceraria) have been cultivated the world over for food and crafted into canteens, instruments and other utilitarian goods. But just how they became globally ubiquitous by the Early Holocene has long been a subject of debate among anthropologists and archaeologists. Some scientists thought the plant migrated with humans from Africa to Asia and, eventually, across the Bering land bridge to the Americas. But a new study suggests it’s unlikely the plants would have survived the long trek through harsh Arctic conditions, and instead offers a different globe-tripping hypothesis for everyone’s favorite dried fruit-turned-drinking vessel.
