According to people living in the surrounding communities, the studied plants are considered toxic, with occasional cases of children intoxication caused by seed ingestion. The polylectic behavior of stingless bees has been reported in previous work, and this is due to the different sources of pollen that they forage for food.

Insect flower visitors and pollinators To determine insect pollinators and visitors, observations were made on ten inflorescences from independent plants, from — h at intervals of 10 min.
The second group only gathered eight accessions, the majority from the population of Istmo. In the second analysis of hierarchical ascendant classification dendrogram or cluster analysis 90 accessions from the Chiapas state were studied and our results showed five groups Fig. Charlesworth Charlesworth D. It has been hypothesized that sex chromosomes evolved from autosomes and have required at least two evolutionary events for the transition from hermaphroditism to dioecism Charlesworth, The relationship between populations and centroids were plotted in Fig.
Male flowers started opening two days after the female flowers, and lasted up to 13 days, with the highest peaks between days 8 and Characteristics of physic nut, Jatropha curcas L. Governing Through Slavery in Colonial Quito.
Accessions from central Chiapas were mostly in Group A orange. In female flowers occasional variation was found in the number of ovules two, three or four. Flowers regularly opened over an average period of 15 days Fig.

We found two Veracruz accessions in another group, whose ancestors might be shipped ccurcas Port of Veracruz to the Old World, to be the source of all African and Asian Jatropha.

Yasuhisa Yushio, and Mr. The reviewer NO declared a shared affiliation, with no collaboration, with one of the authors MY to the handling Editor. Case Studies from the Drylands of Latin America. We identified three genetic groups in Mesoamerica, whose distribution revealed a distinct geographic cline. In our study, we found some Group B accessions from Veracruz and Guatemala were genetically close to Curcaz and Asian accessions Supplementary Table 7.
Characterization and preservation of a diverse collection of Jatropha accessions, including those from Mesoamerica, is the key step to develop them.
Ruiz Ruiz M. The aim of this study was to characterize the pollination process katropha J. All data analyses were performed based on the genotype data matrix.
