Photosynthesis and water relations of savanna tree species differing in leaf phenology.
Ernesto Medina,Marta Francisco +1 more
TL;DR: Godmania macrocarpa Hemsley, a deciduous tree characteristic of fire protected areas of the savanna region of central Venezuela, was more drought tolerant, allocated more N to leaves and had consistently higher photosynthetic rates than Curatella americana L., a ubiquitous species growing successfully within the grasslands of tropical American savannas.
Journal ArticleDOI
Spatial variability of soil nutrients in disturbed riverine mangrove forests at different stages of regeneration in the San Juan River Estuary, Venezuela
Victor H. Rivera-Monroy,Robert R. Twilley,Ernesto Medina,E. Barry Moser,Leonor Botero,Ana Marta Francisco,Evelyn Bullard +6 more
TL;DR: In this article, the effect of forest disturbance on nutrient spatial distributions was evaluated in two mangrove sites (B7 and B9) dominated by the rhizophora mangle along the San Juan River, Venezuela.
Halophytism in plants of the Caribbean coast of Venezuela: halophytes and halotolerants
TL;DR: To determine their degree of halophytism it was analyzed the mineral composition and stable isotopes (13C, and 15N) of leaf material and associated soils of leaves of Syria and Iraq.
Halofitismo en plantas de la costa caribe de venezuela: halófitas y halotolerantes
TL;DR: In this paper, the mineral composition and stable isotopes (13C, and 15N) of leaf material and associated soils were analyzed to determine their degree of halophytism.
Journal ArticleDOI
Isotopic signatures and nutrient relations of plants inhabiting brackish wetlands in the northeastern coastal plain of Venezuela
TL;DR: In this paper, soil, water, and plants along a 1.5 km transect located near the confluence of the Guanoco and San Juan Rivers (Sucre and Monagas States, Venezuela) were analyzed to test the hypotheses that mangrove distribution is strongly associated with salinity of interstitial water and they occupy areas where tidal influence and sediment dynamics determine a relatively open N cycle.
