| The respiration rate (RR) (CO2 production), activation energy (Ea) and Q10 of maleic hydrazide-treated onion bulbs (Allium cepa, cv. Rouge Amposta) at 20.10-6 mol.L-1 (MH1) and 45.10-6 mol.L-1 (MH2) were measured at 4, 10 and 20ºC. Immediately after treatment, the Q10 of MH-treated and control bulbs were not significantly different. After 8 weeks of storage, Q10 of control and both MH-treated bulbs increased and ranged from 2.34 and 2.89. Respiration rate of onions increased during storage, and after 24 weeks, RR values of control, MH1 and MH2 were 0.43, 0.32 and 0.26 mmol CO2.kg-1.h-1 at 20ºC respectively; and 0.26, 0.20 and 0.17 mmol CO2.kg-1.h-1 at 10ºC respectively. At 4ºC, no significant difference was observed between control and MH-treated bulbs.... |

| Se modeló la distribución potencial del bosque mesófilo de montaña (BMM) para los estados de Hidalgo, Puebla y Veracruz, México bajo el escenario A2 de cambio climático (2050 y 2080) con los modelos de circulación general (GCM) CCSM3 y ECHAM5. Se utilizaron técnicas de modelado de hábitat (MH), modelado de nicho (MN) y especies arbóreas estructuralmente importantes y restringidas al BMM. Para caracterizar las condiciones ambientales, se integró un Sistema de información Geográfica (SIG) de 5 variables ambientales, 5 variables de distancia euclidiana y 19 variables bioclimáticas. De la Red Mundial de Información sobre Biodiversidad (REMIB) se obtuvieron 872 registros únicos de 12 especies arbóreas del BMM. Con datos de REMIB y del SIG se ajustaron los MN... |
