Fabaceae emerge as amongst the most embolism-resistant tree families in Amazonia. Forests in the Brazilian and Guiana Shield regions, where Fabaceae abundance is high, are expected to have greater drought resistance than Western Amazon forests.
Large-scale patterns of tropical forest embolism resistance mapped across space and angiosperm phylogeny.
Combining measurements across the Amazon with 100s of floristic samples, Julia Tavares & colleagues report remarkable variation in vulnerability to drought.

Wood density matters.
Intraspecific environmental effects strongly track interspecific patterns (r = 0.83) but are 70–80% smaller.

#newspecies discovered deep in the swamps of the Peruvian Amazon, and named Zamia urarinorum in honor of the indigenous people of the area, who, of course, already knew it.

A study in Nature Ecology & Evolution shows the long-term changes in tree species diversity across tropical forests in the Andes and Amazon. go.nature.com/45FPc1M 🌍 🧪
New study shows that historical #deforestation has substantially altered regional #precipitation over the southern #Amazon basin, with #climate models underestimating this effect. www.nature.com/articles/s41...
Each square metre of Amazon forest produces 300 litres of rainfall a year.
The plants of the Brazilian Amazon create rainfall worth US$20 billion annually.

🌳💧The Brazilian Legal Amazon region delivers rainfall generation worth US$20 ± 7 billion annually, with each meter squared of forest contributing 300 L of water per year.

Es fundamental conservar los bosques remanentes donde la Amazonia contacta con los Andes. Solo si permanecen en pie podrán ofrecer refugio a las especies de las tierras bajas adyacentes.

We all love trees. But lianas are beautiful too!
Cross-sections reveal the pattern of xylem tubes, reflecting the stem space dedicated to transporting water skywards and phylogenetic variation in a liana community.
Really important for so many things. "The value of patient observation compounds over time but remains invisible to short-term metrics" has profound implications.
Why long-term science is needed in a short term world.

How much temperate rainforest could there be in the UK and Ireland, and where? Despite campaigns calling for restoration in both countries, these questions have been difficult to answer. In our new paper we assess the evidence base 🌏🧪🌐🌳🌲 1/9

Brazil’s Santo Antônio dam on the Madeira River has cut fish populations by up to 90% in parts of Amazonas and Rondônia, a new community-led study finds.
Species like pirarucu and tambaqui have largely vanished. “The Madeira River stopped flowing,” one fisher said.

There are so many fucked up things with the current administration that it's hard to focus on one but this recent move is basically a death sentence for the planet. I've been involved with more boots on the ground actions over the years than I can count and this really bums me out.

The sheer size of the tropics is underestimated by many.
