Niche differentiation can lead to coexistence of plant species by partitioning limiting resources. Light partitioning promotes niche differentiation in tropical humid forests, but it is unclear how niche partitioning occurs in tropical dry forests where both light and soil resources can be limiting. We studied the adult niche of four dominant evergreen (cycad, palm) and drought-deciduous (legume, oak) species co-occurring along environmental gradients. We analyzed light intensity and soil… Expand
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. Expand
Leaf nutrient concentrations associated with phylogeny, leaf habit and soil chemistry in tropical karst seasonal rainforest tree species
The results suggest that stabilizing selection combined with the biochemical constraints could select the locally adapted evergreen and deciduous species with sufficient phylogenetic variations to produce leaf nutrient concentrations and certain nutrient combinations that should be well-fitted in tropical karst environments. Expand
Drier tropical forests are susceptible to functional changes in response to a long-term drought.
It is found that drier tropical forests have increased their deciduous species abundance and generally changed more functionally than forests growing in wetter conditions, suggesting an enhanced ability to adapt ecologically to a drying environment. Expand
A trait-based approach to the conservation of threatened plant species
Abstract Traditionally the vulnerability of threatened species to extinction has been assessed by studying their environment, genetics and population dynamics. A more comprehensive understanding ofExpand
Resilience of seed production to a severe El Niño‐induced drought across functional groups and dispersal types
It is suggested that ENSO-induced drought mediates the establishment of functional groups and dispersal types suited for early successional conditions with more open canopies and reduced competition among plants. Expand
Plant functional trait structure in two fog deserts of America.
Abstract Regions with similar environmental determinants are known to produce the independent evolution of similar features in unrelated species. This hypothesis is pervasive in ecology evolution andExpand
Understanding and predicting frost-induced tropical tree mortality patterns.
Investigating the effects of two major local factors, topography and forest successional type, on climate-induced tropical tree mortality patterns using an observational and modeling approach found higher occurrence probabilities of frost-induced tree mortality at lowland forests can be explained by the strong influence of elevation on temperature distribution.

The Accumulated Response of Deciduous Liquidambar formosana Hance and Evergreen Cyclobalanopsis glauca Thunb. Seedlings to Simulated Nitrogen Additions
The results indicate that the deciduous L. formosana would be more susceptible to elevated N availability even if both species received similar N allocation, which may be attributed to the lower water potential at 50% of conductivity lost for C. glauca, which enables higher hydraulic safety at the cost of a weak increase in Amax.

Structural diversity as a predictor of ecosystem function
Biodiversity is believed to be closely related to ecosystem functions. However, the ability of existing biodiversity measures, such as species richness and phylogenetic diversity, to predictExpand
Characterizing Canopy Openness Across Large Forested Landscapes Using Spherical Densiometer and Smartphone Hemispherical Photography
Canopy openness is an important forest characteristic related to understory light environment and productivity. Although many methods exist to estimate canopy openness, comparisons of theirExpand


Leaf phenology is associated with soil water availability and xylem traits in a tropical dry forest
To understand the environmental drivers of variation in leaf phenology and xylem function, the relation of soil water potential to topographic metrics derived from a digital elevation model was explored and evergreen species had lower xyleM specific conductivity than deciduous species. Expand
Functional traits determine trade-offs and niches in a tropical forest community
The trait-based biophysical model explains how functional traits cause functional divergence across species and whether such divergence contributes to niche separation along resource gradients. Expand
Distinct Leaf‐trait Syndromes of Evergreen and Deciduous Trees in a Seasonally Dry Tropical Forest
It is suggested that deciduous and evergreen trees could respond to differential water availability and herbivory in their respective habitats by converging on distinct leaf-trait syndromes. Expand
Enhancing Ecosystem Function through Conservation: Threatened Plants Increase Local Carbon Storage in Tropical Dry Forests
The role of plant diversity, particularly of rare species, in ecosystem functioning (e.g., carbon storage) has been mostly studied in temperate systems with little practical application to theExpand
Cost-benefit relationships in deciduous and evergreen leaves of tropical dry forest species
Leaves of six deciduous and four evergreen species were analysed to compare their construction and maintenance costs, maximum CO2 assimilation capacity (Amax) and potential (instantaneous) NUE and WUE, and it was hypothesized that they should have contrasting strategies underlying their nitrogen-use efficiency (NUE) and water- use efficiency (WUE).

Light-dependent leaf trait variation in 43 tropical dry forest tree species.
Overall plasticity was modest and rarely associated with juvenile light requirements, adult stature, or ontogenetic changes in crown exposure, and short-lived pioneers had the highest trait plasticity. Expand
Leaf traits show different relationships with shade tolerance in moist versus dry tropical forests.

For forests differing in rainfall seasonality, there is a shift in the relative importance of functional leaf traits and performance trade-offs that control light partitioning, whereas in the seasonally deciduous forest leaf traits underlying the growth trade-off between low and high light might become important.

Coordinated evolution of leaf and stem economics in tropical dry forest trees.
Across biomes, rather than a fundamental trade-off underlying a single axis of trait covariation, the relationship between leaf and stem economics is likely to occupy a wide space in which multiple combinations are possible. Expand
Adaptive significance of evergreen vs. deciduous leaves : solving the triple paradox
A generalized optimality model is outlined to account for evergreen dominance and other patterns in leaf longevity and phenology, based on maximizing whole-plant carbon gain or height growth, and building on recent advances in the understanding of the quantitative relationships of leaf photosynthesis, nitrogen content, and mass per unit area to leaf life-span.

Drought tolerance as a driver of tropical forest assembly: resolving spatial signatures for multiple processes.
The ability of drought-tolerance traits, other physiological traits, and commonly measured functional traits to predict the spatial patterns expected from the assembly processes of habitat associations, niche-overlap-based competition, and hierarchical competition was compared. Expand
