Plant biodiversity drivers in Brazilian campos rupestres : insights from phylogenetic structure
(2017-12-19) - Journal article,
Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil’s campos rupestres (rupestrian grasslands) ...
Synthesis centers as critical research infrastructure
(2017-08) - Journal article,
Synthesis centers offer a unique amalgam of culture, infrastructure, leadership, and support that facilitates creative discovery on issues crucial to science and society. The combination of logistical support, postdoctoral ...
Disassortative mating prevails in style-dimorphic Narcissus papyraceus despite low reciprocity and compatibility of morphs
(2015-09) - Journal article,
Evolution to reduce inbreeding can favor disassortative (inter-morph) over assortative (intramorph) mating in hermaphroditic sexually polymorphic plant species. Heterostyly enhances disassortative pollination through ...
The role of edaphic environment and climate in structuring phylogenetic pattern in seasonally dry tropical plant communities
(2015-03-23) - Journal article,
Seasonally dry tropical plant formations (SDTF) are likely to exhibit phylogenetic clustering owing to niche conservatism driven by a strong environmental filter (water stress), but heterogeneous edaphic environments and ...
Rapidly evolving genes and stress adaptation of two desert poplars, Populus euphratica and P. pruinosa
(2013-06-11) - Journal article,
Understanding which genes have evolved rapidly with the recent tree speciation in arid habitats can provide valuable insights into different adaptation mechanisms. We employed a comparative evolutionary analysis of expressed ...
Green plants in the red : a baseline global assessment for the IUCN Sampled Red List Index for Plants
(2015-08-07) - Journal article,
Plants provide fundamental support systems for life on Earth and are the basis for all terrestrial ecosystems; a decline in plant diversity will be detrimental to all other groups of organisms including humans. Decline in ...
Do species conservation assessments capture genetic diversity?
(2014-12) - Journal article,
The best known system for classifying threat status of species, the IUCN Red List, currently lacks explicit considerations of genetic diversity, and consequently may not account for potential adaptation of species to future ...
Models incorporating chromatin modification data identify functionally important p53 binding sites
(2013-06) - Journal article,
Genome-wide prediction of transcription factor binding sites is notoriously difficult. We have developed and applied a logistic regression approach for prediction of binding sites for the p53 transcription factor that ...
