We investigated vegetation structure, seasonal water use and leaf deciduousness in a seasonally dry forest of Dzibilchaltún, Mexico. Legumes, species which tend to dominate these forests, have an array of water-saving traits. We explored whether legume species had reduced water use under similar growth conditions as other non-legume species of this(More)
In seasonally dry environments maintaining year-round production of silvopastoral systems can be challenging due to drought effects on vegetation. Different tree species native to dry forests may show contrasting strategies to deal with drought, which could impact silvopastoral productivity. We assessed the differential effect of drought on seedlings of(More)
Studies of metapopulations of epiphytic bromeliads have been useful to test dispersal limitations and niche effects on the distribution of species, but most studies have been done in wet forests. To advance understanding of these processes in dry environments and using additional microclimatic data, we examined the horizontal distribution, vertical(More)
Functional Diversity is considered an important driver of community assembly in environmental and successional gradients. To understand tree assembly processes in a semideciduous tropical forest, we analyzed the variation of Functional Richness (FRic), Functional Divergence (FDiv), and Functional Evenness (FEve) of small vs. large trees in relation to(More)
Atmospheric nitrogen deposition poses a major threat to global biodiversity. Tropical epiphytic plants are especially at risk given their reliance on atmospheric sources of nutrients. The leaf, pseudobulb, and root carbon and nitrogen content, C:N ratio, as well as the nitrogen isotopic composition were studied for individuals of Laelia speciosa from a city(More)
Epiphytic orchids from dry forests of Yucatán show considerable photoprotective plasticity during the dry season, which depends on leaf morphology and host tree deciduousness. Nocturnal retention of antheraxanthin and zeaxanthin was detected for the first time in epiphytic orchids. In tropical dry forests, epiphytes experience dramatic changes in light(More)
