Tree Rings in the Tropics: Insights Into the Ecology and Climate Sensitivity of Tropical Trees

Tree Physiology, 2016
Tree-ring studies provide important contributions to understanding the climate sensitivity of tropical trees and the effects of global change on tropical forests. This chapter reviews recent advances in tropical tree-ring research. In tropical lowlands, tree ring formation is mainly driven by seasonal variation in precipitation or flooding , and not in

An Estimate of the Number of Tropical Tree Species [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2015
Significance People are fascinated by the amazing diversity of tropical forests and will be surprised to learn that robust estimates of the number of tropical tree species are lacking. We show that there are at least 40,000, but possibly more than 53,000, tree species in the tropics, in contrast to only 124 across temperate Europe ...

Consequences of defaunation for a tropical tree community

Ecology Letters, 2013
AbstractHunting affects a considerably greater area of the tropical forest biome than deforestation and logging combined. Often even large remote protected areas are depleted of a substantial proportion of their vertebrate fauna. However, understanding of the long‐term ecological consequences of defaunation in tropical forests remains poor.

Phenology of temperate trees in tropical climates

International Journal of Biometeorology, 2005
Several North American broad-leaved tree species range from the northern United States at approximately 47 degrees N to moist tropical montane forests in Mexico and Central America at 15-20 degrees N. Along this gradient the average minimum temperatures of the coldest month (T (Jan)), which characterize annual variation in temperature, increase from ...

More trees in the tropics

Area, 2004
Repeat photography is the process of rephotographing the same scene that appears in an earlier photograph. As a methodology, repeat photography is a valuable tool for investigating and assessing landscape change. Beyond the disadvantages of scale, composition, areal coverage and temporal punctuation, the method is useful.

TOWARDS A CLASSIFICATION OF TROPICAL FRUIT TREES

Acta Horticulturae, 1986
The classification reveals a pattern in the confusing multitude of tree crops; its usefulness is enhanced because of similarities in ecology and fruitfulness of the species within a class. The contrast between the fruitful, continuously growing single-stemmed species and the rather unfruitful, rhythmically growing branched species is striking.

Tropical consensus trees

Consensus trees serve as a means to summarize tree data in the context of phylogenetic studies. Geometrically, they can be conceptualized as location statistics within the space of phylogenetic trees. This thesis is centered on novel approaches to consensus methods that harness the tropical convexity inherent to the tree space.
