What to know about Forest floors reveal overlooked seed dispersers: Slugs, beetles and crabs spread viable seeds

A review led by The University of Hong Kong, published in Trends in Plant Science, highlights the role of small invertebrates like slugs, beetles, and crabs in seed dispersal. The research suggests these animals provide a critical mechanism for plant regeneration, particularly in ecosystems where larger animal dispersers have declined.

Forest floors reveal overlooked seed dispersers: Slugs, beetles and crabs spread viable seeds Swati Mestri Scientific Editor Robert Egan Senior Editor A review led by the School of Biological Sciences at The University of Hong Kong (HKU) has revealed that…

Why it matters

Led by Professor Si-Chong Chen from the School of Biological Sciences, the review, published in Trends in Plant Science, synthesizes global evidence showing that invertebrates such as slugs, earthworms, beetles, crickets and crabs can consume seeds and later…

Common ground

The findings highlight an important but underappreciated pathway of seed dispersal that may help sustain plant regeneration, especially in fragmented or degraded ecosystems where larger animal dispersers are declining.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Claim 1: “the review, published in Trends in Plant Science, synthesizes global evidence showing that invertebrates such as slugs, earthworms, beetles, crickets and crabs can consume seeds and later excrete them while they remain viable.”
CORROBORATED
Web sources explicitly list slugs, earthworms, beetles, crickets, and crabs as invertebrates that can disperse seeds, and reference the review's focus on these vectors.
