Seasonally dry tropical forests are dominated by deciduous and evergreen tree species with a wide range of leaf phenology. We hypothesized that Piscidia piscipula is able to extend leaf senescence until later in the dry season due to deeper and more reliable water sources than Gymnopodium floribundum, which loses leaves earlier in the dry season. Physiological performance was assessed as timing of leaf production and loss, growth, leaf water potential, depth of water uptake determined by stable… 

Seasonal water use strategy of Cyclobalanopsis glauca in a karst area of southern China

Subtropical evergreen and deciduous broadleaved mixed forests occur on shallow soils or even barren areas with carbonate bedrock in karst areas of southern China. The nature of seasonal water sources

Consequences of drought severity for tropical live oak (Quercus oleoides) in Mesoamerica.

Evidence for linear trends toward aridification with increases of return periods of drought for October SPEI-24 declining from 42 to 6 yr in Costa Rica and from 21 to 7 yr in Honduras and recent occurrence of multiyear droughts from 2013 to 2016 is found.

Rooting depth, water relations and non-structural carbohydrate dynamics in three woody angiosperms differentially affected by an extreme summer drought.

The data support the hypothesis that drought-induced tree decline is a complex phenomenon that cannot be modelled on the basis of single predictors of tree status like hydraulic efficiency, vulnerability and carbohydrate content and highlight the role of rooting depth in seasonal progression of water status, gas exchange and NSC.

Leaf habits and their relationship with leaf and wood traits in tropical dry forests

This work has reviewed the literature focusing mainly on tropical dry forests and relationships among leaf habits (evergreen and deciduous) and other leaf and wood traits and provides a meta-analysis of these traits from Neotropics.

Vineyard water relations in a karstic area: deep roots and irrigation management

Plant ecology of tropical and subtropical karst ecosystems

Substantial areas of tropical forests, including those within nine tropical biodiversity hotspots, contain karst landscapes that have developed on soluble carbonate rocks. Here, we review how the

Drought Survival Strategies of Tropical Trees

Little is known about the role of photosynthetic stems or cuticular conductance during extreme extended drought, making these processes a high priority for a complete understanding of tropical tree physiology during drought.

Common Species Maintain a Large Root Radial Extent and a Stable Resource Use Status in Soil-Limited Environments: A Case Study in Subtropical China

Evidence is provided that plants growing in soil-limited environments maintain a stable resource use status along with large radially extended coarse root systems in humid karst regions like southwest China.



Water source partitioning among trees growing on shallow karst soils in a seasonally dry tropical climate

Data indicate that native trees growing on shallow karst soils in northern Yucatan use little or no groundwater and depend mostly on water stored within the upper 2–3 m of the soil/bedrock profile.

Water relations of evergreen and drought-deciduous trees along a seasonally dry tropical forest chronosequence

The rapid development of deep roots appears to be an important strategy enabling evergreen species to overcome seasonal water limitation, whereas, in addition to losing a portion of their leaves, drought-deciduous trees minimize water loss from remaining leaves during the dry season.


Leaf phenology was monitored for 49 woody species (trees and tall shrubs) each month over a 2.5-year period in a humid, wet-dry tropical eucalypt savanna at Solar Village, near Darwin, Australia, consistent with hypotheses that leaf phenology in trees from the wet- dry tropics is largely controlled by endogenous mechanisms.

Leaffall Phenology in a Subtropical Wet Forest in Puerto Rico: From Species to Community Patterns

Leaffall phenology is an important periodical event in forests, contributing to mobilization of organic matter from primary producers to soil. For seasonal forests, leaffall periodicity has been

Partitioning of water resources among plants of a lowland tropical forest

In evergreen shade-tolerant and high-light requiring shrubs and small trees, δD of xylem water was negatively correlated with transpiration rate and leaf water potential indicating that species using deeper, more abundant water resources had both higher rates of water use and more favorable leaf water status.

Coordinated changes in photosynthesis, water relations and leaf nutritional traits of canopy trees along a precipitation gradient in lowland tropical forest

This study links coordinated change in leaf functional traits that affect productivity and nutrient cycling to seasonality in lowland tropical forests with contrasting mean annual precipitation.

Utilization of bedrock water by Brosimum alicastrum trees growing on shallow soil atop limestone in a dry tropical climate

Adult evergreen Ramón (Brosimum alicastrum Sw. Moraceae) trees can thrive on the shallow soils atop limestone of northern Yucatan despite limited soil water storage capacity, and do not require

Linking water sources with foliar nutrient status in upland plant communities in the Everglades National Park, USA

Plant communities within an ecosystem can vary in water source usage and nutrient availabilities, thus permitting community coexistence and diversity. We investigated the differences in water source

Partitioning of soil water among canopy trees in a seasonally dry tropical forest

Comparison of xylem, soil, and groundwater δD values pointed to spatial and temporal partitioning of water resources among several tropical forest canopy tree species during the 1997 dry season, which was associated with leaf phenology.
