Further evidence for endozoochory in a mycoheterotrophic orchid Cyrtosia septentrionalis: seed dispersal by the masked palm civet Paguma larvata
Cyrtosia septentrionalis, an orchid species, is notable for its sausage‐shaped red fleshy fruits, which can reach up to 10 cm in length. Previous research identified frugivorous and omnivorous birds, especially the brown‐eared bulbul Hypsipetes amaurotis (Pycnonotidae, Passeriformes), as key seed dispersers of C. septentrionalis in natural habitats. This finding challenges conventional belief that orchid seeds are primarily wind‐dispersed. Moreover, given the rarity of specialized co‐evolutionary relationships between fruits and frugivores, C. septentrionalis may also rely on mammals for seed dispersal in certain regions.We aimed to explore the fruit consumption habits of animals other than birds. Motion sensor‐equipped cameras were used to observe interactions with the fruits of C. septentrionalis and assess the viability of seeds post‐consumption.The observations revealed three animal species consuming the fruits, with the masked palm civet Paguma larvata (Viverridae, Carnivora) identified as a dominant consumer in the investigated population. Microscopy analysis of seeds retrieved from P. larvata faeces indicated that the seeds remained intact and viable after passing through the digestive system of this carnivorous mammal.The above discovery suggests a potential role for carnivorous mammals in seed dispersal of C. septentrionalis, alongside birds, thus broadening our understanding of the complex seed dispersal strategies employed by orchids.
期刊介绍:
Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology.
Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
