Data from: Determinants of tree cover in tropical floodplains
In uplands, water availability and fire limit tree cover, differentiating between tropical forest, savanna, and grassland biomes. In contrast, we know less about tropical floodplain tree cover determinants, although these habitats similarly include near-treeless grasslands, moderately treed savannas, and forests. Using GIS and remotely sensed data from 13 large tropical and sub-tropical floodplain ecosystems on five continents, we show that floodplain tree cover increases with climatic water balance (= rainfall - potential evapotranspiration) and decreases with frequent fire, as in uplands. Additionally, in floodplains, higher elevations and steeper slopes have higher tree cover, likely because these areas escape the worst inundation. Moreover, the effects of fire and topography are stronger in wetter regions. More prolonged and frequent flooding also reduce tree cover in climatically wetter floodplains but increase it in drier ones, although the effects are surprisingly weak compared to those of water balance, fire, and topography. Opposite to uplands, sandier soils have lower tree cover, likely because the benefits presented by deep tree roots in uplands are less important in floodplains with abundant water. While outright wetland conversion proceeds globally, floodplain tree cover faces other anthropogenic threats, like changing fire frequency and dam construction, especially in wet climates.

Comparative transcriptomics of tropical woody plants supports fast and furious strategy along the leaf economics spectrum in lianas
<p>Lianas, climbing woody plants, influence the structure and function of tropical forests. Climbing traits have evolved multiple times, including ancestral groups such as gymnosperms and pteridophytes, but the genetic basis of the liana strategy is largely unknown. Here, we use a comparative transcriptomic approach for 47 tropical plant species, including ten lianas of diverse taxonomic origins, to identify genes that are consistently expressed or downregulated only in lianas. Our comparative analysis of full-length transcripts enabled the identification of a core interactomic network common to lianas. Sets of transcripts identified from our analysis reveal features related to functional traits pertinent to leaf economics spectrum in lianas, including upregulation of genes controlling epidermal cuticular properties, cell wall remodeling, carbon concentrating mechanism, cell cycle progression, DNA repair and a large suit of downregulated transcription factors and enzymes involved in ABA-mediated stress response as well as lignin and suberin synthesis. Altogether, these genes are known to be significant in shaping plant morphologies through responses such as gravitropism, phyllotaxy and shade avoidance.</p>
