New Plant Found in Andes
Supports up to 50 Species, Researchers Say

Specialist herbivore Eios feeds on P. kelleyi
Researchers working in the Ecuadorian Andes have discovered a new species of black pepper plant
that is a nexus of biodiversity. The plant, named Piper kelleyi
, supports roughly 40 to 50 insect species, the scientists estimate, many of which are entirely dependent on the plant for survival. P. kelleyi
produces chemical compounds that are known to deter most herbivores, but a single type of caterpillar has adapted to overcome the toxicity of the plant's defenses. That caterpillar, in turn, is preyed upon by species of wasps and flies dependent on that specific caterpillar species — and ultimately the plant — for survival. Altogether, an assemblage of up to 50 species of herbivorous and predatory insects are dependent on P. kelleyi
, the researchers report in the journal PhytoKeys
. Many of these insect species have never been studied, but researchers believe the toxic compounds produced by plants like P. kelleyi
drive the evolution of new species of herbivorous and predatory insects.
