“…Each of these regions has a floristic diversity that supports beekeeping and meliponiculture, obtaining honeys with diverse physicochemical characteristics and distinctive organoleptic characteristics (IEFYS, 2014) The low deciduous forest is important not only for its particular floristic richness, with more than 50 % of the genera and species identified in lowland forest, but also for its high proportion of endemic species (IEFYS, 2014). Observing a diversity of native plant species, approximately 2 400 species recorded to date, of which 600 are melliferous and 30 of them considered of great beekeeping importance (Castillo et al, 2016). And it is there where the apibotanical cycle, which includes the seasons of pre-harvest from October to December, harvest from January to May and post-harvest from June to September (Alfaro et al, 2010), has a close relationship with environmental conditions, which affect the flowering of plants and honey production, thus presenting wide fluctuations throughout the year (Cruz, 2017).…”

The Melipona beecheii honey has bioactive compounds with high antioxidant activity that influence its colour. This research evaluated the influence of phenolic compounds and flavonoids on the colour and antioxidant activity of M. beecheii honeys. Forty-three honey samples from different site located in the low deciduous forest of Yucatan, Mexico, were extracted during the harvest and post-harvest seasons (2020 – 2021). The Pfund method was used to measure colour, Folin-Ciocalteu method for phenols measurement, aluminum chloride method for flavonoids determination, and ABTS and DPPH IC50 assay to determine antioxidants. The predominant colour of the honey was extra light amber and light amber at both seasons. Phenols ranged from 780 to 1317 mg/kg GAE; flavonoids from 36 to 55 mg/kg CE and antioxidant were 675 to 1161 µmol/kg TEAC by the ABTS and 361.8 to 173.0 mg/mL by the DPPH IC50. Phenols and flavonoids were correlated with colour and radical scavenging activity, indicating the influence of these compounds with the darker colour and higher antioxidant activity of honey. The statistically significant difference (P<0.05) between seasons could be associated with the botanical origin with great diversity of melliferous flora present in the low deciduous forest of the Yucatan Peninsula. Keywords: Antioxidant; colour; flavonoids; honey; Melipona beecheii.

“…En el estado de Yucatán, la selva baja caducifolia se caracteriza por una diversidad de especies de plantas nativas, aproximadamente 2400 registradas a la fecha; 600 de ellas son melíferas y 30 se consideran de gran importancia apícola (13). En esta ecorregión es donde el ciclo apibotánico, que comprende las temporadas de precosecha de octubre a diciembre, cosecha de enero a mayo y poscosecha de junio a septiembre, tiene una estrecha relación con las condiciones ambientales que afectan la floración y la producción de miel (14).…”

Calidad microbiológica y actividad antibacteriana de miel producida por Melipona beecheii en Yucatán, México

et al. 2023

Objetivo. Analizar la calidad microbiológica y actividad antibacteriana en 43 muestras de miel producida por Melipona beecheii, extraída durante las épocas de cosecha (enero a mayo del 2020 y 2021) y poscosecha (junio a octubre 2020) de meliponarios ubicados en selva baja caducifolia del Sureste de México. Materiales y métodos. La calidad microbiológica se determinó evaluando el contenido de mesófilos aerobios totales, coliformes, hongos, levaduras y anaerobios formadores de esporas. Para la actividad antibacteriana, se utilizó el ensayo de difusión en agar con pocillos utilizando concentraciones de miel al 5, 10, 20, 40 y 80%. Resultados. Se observó la presencia de mesófilos aerobios (83.7% de las muestras), coliformes (4.6%), mohos (20.9%) y levaduras (39.5%), con un máximo de 4.5x102, 2.5x10, 9.5x10 y 3.2x103 UFC/g, respectivamente. En ninguna muestra se observó la presencia de formas esporuladas de clostridios sulfito reductores. Con respecto a la actividad antibacteriana las mayores zonas de inhibición se registraron contra Staphylococcus aureus a una concentración de la miel al 80 y 40%, contrario a lo observado con Salmonella var. Typhimurium, Pseudomonas aureginosa y Escherichia coli, en donde la interferencia en el crecimiento bacteriano no fue tan evidente. Conclusiones. No obstante, el crecimiento de mesófilos y levaduras en la mayoría de las muestras, éstas presentaron actividad antibacteriana contra los patógenos referidos, lo cual puede ser atribuido a las interacciones entre microbioma, plantas, abejas y características fisicoquímicas de la miel.

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.
