An estimate of the number of tropical tree species. [PDF]

open access: yesProc Natl Acad Sci U S A, 2015
SignificancePeople 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.

A catastrophic tropical drought kills hydraulically vulnerable tree species [PDF]

open access: yesGlobal Change Biology, 2020
AbstractDrought‐related tree mortality is now a widespread phenomenon predicted to increase in magnitude with climate change. However, the patterns of which species and trees are most vulnerable to drought, and the underlying mechanisms have remained elusive, in part due to the lack of relevant data and difficulty of predicting the location of ...

Consistent patterns of common species across tropical tree communities [PDF]

open access: yesNature
AbstractTrees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge.

Soil nutrients influence spatial distributions of tropical tree species [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
The importance of niche vs. neutral assembly mechanisms in structuring tropical tree communities remains an important unsettled question in community ecology [Bell G (2005) Ecology 86:1757–1770]. There is ample evidence that species distributions are determined by soils and habitat factors at landscape (<10

Biodiversity shapes tree species aggregations in tropical forests

open access: diamondNature Precedings, 2008
AbstractSpatial patterns of conspecific trees are considered as the consequences of biological interactions and environmental influences. They also reflect species interactions in plant communities. However, biological attributes are often neglected while deliberating the factors shaping species distributions.

Flood tolerance of four tropical tree species [PDF]

open access: yesTree Physiology, 1999
Many seasonally flooded habitats in the tropics are dominated by one or a few tree species. We tested the hypothesis that the inability to tolerate flooding restricts most species from becoming established in flood-prone habitats. We compared morphological and physiological responses to flooding in seedlings of Prioria copaifera Griseb., a species that

Tropical and subtropical Asia's valued tree species under threat [PDF]

open access: yesConservation Biology, 2022
Abstract Tree diversity in Asia's tropical and subtropical forests is central to nature‐based solutions. Species vulnerability to multiple threats, which affect provision of ecosystem services, is poorly understood. We conducted a region‐wide, spatially explicit assessment of the vulnerability of 63 socioeconomically important tree ...

Effect of Bonding on the Structure and Properties of Nanocellulose Films

open access: yesBioResources, 2022
In this study, cellulose nanofibers (CNF) were obtained by chemical pretreatment using a rubberwood substrate. Different forms of drying were used to prepare three CNF film variants.

Third-Generation Sequencing Reveals LncRNA-Regulated HSP Genes in the Populus x canadensis Moench Heat Stress Response

open access: yesFrontiers in Genetics, 2020
Long non-coding RNAs (lncRNAs) regulate plant responses to abiotic stresses. However, the short reads produced by second-generation sequencing technology make it difficult to accurately explore full-length transcripts, limiting the study of lncRNAs.
