The ethnobotanical importance of the family Piperaceae is recognized mainly for its medicinal properties. A total of 106 species of two genera of this family (Piper and Peperomia) have been collected in Oaxaca, but only 18 are recorded in scientific publications as medicinal, edible, veterinary, or ritual plants. The objectives of this study are to describe the traditional knowledge and uses of the Piperaceae in areas of high biocultural diversity of Oaxaca and to analyze the relationship between its geographic distribution with ethnobotanical records among ethnic groups. Fieldwork was carried out between 2013 and 2016, and voucher specimens were reviewed in Mexican herbaria. Two multivariate analyses were applied to compare the geographic distribution of Piperaceae with ethnobotanical knowledge in Oaxaca. A total of 13 species of Peperomia, and 7 of Piper were collected, besides some unidentified species of both genera. Seven use categories were registered, with medicinal and edible being the most important. A high percentage (65%) of the species is named in at least one native language. Most species have a single use, mainly medicinal. Peperomia has been collected in Oaxaca since 1980, while Piper since 1960. Multivariate analysis indicated the existence of a differentiated ethnobotanical knowledge of this family among ethnic groups, related to the geographic distribution of species. This study evidences that ethnic groups, who maintain areas of higher biodiversity, obtain these species mainly from the wild, from specific microenvironments; hence, conservation practices must be reinforced for them, as for all ecosystems in general.

“…Moreover, seed retention time in the digestive tract can influence the seed coat because the greater the retention time, the greater the mechanical and chemical abrasion to the seed coat which can lead to variable germination efficiency (Barnea et al 1991;Traveset 1998). Seed retention times were noted to range from 12 to 45 min to several hours for some other species of the genus Pteropus (Funakoshi et al 1993;Shilton et al 1999;De Carvalho-Ricardo et al 2014). According to the fruit species ingested seed retention time went from 37 to 181 min in a New Zealand frugivorous pigeon, Hemiphaga novaeseelandiae, (Clout and Tilley 1992;Wotton et al 2008), and would be about 30 min for a New-Caledonian dove, Ptinolopus greyii, when eating Ficus spp.…”

“…Then seeds were quickly placed on water-wet cotton (humidity 100 %) in transparent Petri dishes. Four replicates of 25 seeds each (pooled from different individual plants and different individual animals) were tested for each treatment (Tassin et al 2010;De Carvalho-Ricardo et al 2014) except for R. exulans, for which very few seeds were obtained from the faeces (n = 12 for Ficus and n = 9 for Freycinetia). There were six ingested seed treatments: R. rattus, R. exulans, P. ornatus, P. tonganus, P. vetulus, and D. goliath.…”

Comparative effects of native frugivores and introduced rodents on seed germination in New-Caledonian rainforest plants.Abstract Native frugivores play an important role in native plant community dynamics by participating in seed dispersal. Today many island forests are invaded by introduced omnivores, such as rats, but their role in dispersing native plants is still little known. Here, we evaluated whether native seeds from New-Caledonian rainforests can germinate after passing through an invasive rat digestive tract and compared seed germinability and germination time between seeds ingested by invasive rats and native frugivores. We offered native fruits of Ficus racemigera and Freycinetia sulcata to the rats Rattus rattus and R. exulans, three flying foxes Pteropus spp. and the pigeon Ducula goliath. Our results showed that seeds can germinate after passing through an invasive rat digestive tract, and suggest that rats can disperse seeds of both plant species. However, invasive rats may be less efficient than native frugivores, as more seeds were destroyed when passing through rat digestive tracts than through native frugivores, and because germinability was lower and germination time was longer for seeds passing through invasive rats than through native frugivores. The reduced efficiency of rats may result from their generalized diet, the structure of their digestive tract, and/or their feeding behavior. In New-Caledonian rainforests, dispersal services on both plant species are likely well fulfilled by flying foxes and Ducula pigeons, but rats do not seem to be as efficient dispersers. Consequently, management measures to protect native frugivores should help to conserve seed dispersal services.

“…The species is an important seed disperser of smallseeded pioneering plants, such as fi gs, and for economically valuable species such as Iroko (Milicia excelsa). Similar to other species of frugivorous bats [1,7], it is thought that handling by Eidolon does not harm, or even enhances, the germination of seeds. Eidolon is also one of the few migratory African bat species, probably following the waxing Correspondence and waning of food resources.…”
