Abstract: RESUMENEl método cuantitativo de reacción en cadena de la polimerasa (qPCR), seguido por análisis de curvas de disociación, fue desarrollado para la detección rápida y simultánea de la composición botánica en mieles de la Península de Yucatán, México. Cinco muestras de miel ciclo apícola 2013 y cinco del 2014, se caracterizaron para definir el contenido de cinco especies de plantas de importancia apícola; Viguiera dentata, Gymonopodium floribundum, Piscidia piscipula, Acacia angustissima y Mimosa bahamensis.

Background and Research Aims Human activities seeking to satisfy various needs have resulted in deforestation and other forest cover change processes. The Natural Protected Areas are among the most efficient instruments to contain forest loss. The compensation from conservation is not sufficient to compete with land uses with higher economic rent, such as timber extraction and food production. This study summarizes the evidence and identifies research gaps on forest processes caused by productive activities in Mexico’s Calakmul Biosphere Reserve. Methods We systematically reviewed the scientific literature investigating forest processes caused by the productive activities in the Calakmul, including the transition zone. We calculated the frequencies of codes on forest processes and productive activities in the entire sample (53), evaluated each code’s significance in the qualitative synthesis and interpretation, and summarized the measurements of forest processes considering only the primary studies (46). Results Deforestation was the most commonly investigated process. Traditional agriculture initially caused deforestation, while livestock and conventional agriculture became more dominant recently with the agricultural intensification policies. Few articles investigated forest degradation experiencing a steady increase from fallow shortening and selective logging. Also, few studies identified forest recovery resulting from long fallows and core zone delimitation. No publications evaluated the forest cover impact of sustainable initiatives. Conclusion The tendency to quantify deforestation on a regional scale masks presence of other forest processes. The rural development programs in Calakmul did not include the environmental perspective, while participation in sustainable initiatives was low. The understanding of productive activities at the local level will allow differentiation of the long-term from temporary forest dynamic. Implications for Conservation To assure resilient and inclusive growth in Calakmul, the reduced-impact logging, sustainable agricultural intensification, improved fallows, and beekeeping should be supported with monetary resources that cover the transaction costs of unsustainable livestock breeding and industrial agriculture.

Pollen Types Reveal Floral Diversity in Natural Honeys from Campeche, Mexico

et al. 2022

View full text Add to dashboard Cite

The Yucatan Peninsula, located in southern Mexico, is a central honey-producing region with extraordinary biodiversity of melliferous plants. Approximately 900 plant species have been described as being a source of nectar and pollen for bees and other pollinators. They provide ecosystem services that help to keep plant biodiversity high and mitigate the effects of climate change. This study aimed to reveal the diversity of the pollen content in honey through a melissopalynological analysis of 22 honey samples collected in February–August 2021 from the north-central area of Campeche, Mexico. The extraction of pollen from the honey was carried out using standard methods for melissopalynological analysis. The honeys were classified by botanical origin to determine their floral sources and a diverse spectrum of 19 pollen types from 13 families was identified. Only eight were predominant: Milleria quinqueflora, Gymnopodium floribundum, Terminalia buceras, Amaranthus spinosus, Zea mays, Talisia floresii, Guazuma ulmifolia, and Croton icche. Our research shows the high quality of the honey analyzed and highlights the diversity and critical role of local melliferous flora and crops in beekeeping development in southern Mexico. The results in this study are useful for confirming the botanical origins of honey, generating information for designing nature conservation and agroecosystem management strategies, and increasing the knowledge of beekeepers in Campeche, Mexico.
