  abstract = {{A}im {P}alms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. {B}eing monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. {W}e quantified global patterns of tree palm relative abundance to help improve understanding of tropical forests and reduce uncertainty about these ecosystems under climate change. {L}ocation {T}ropical and subtropical moist forests. {T}ime period {C}urrent. {M}ajor taxa studied {P}alms ({A}recaceae). {M}ethods {W}e assembled a pantropical dataset of 2,548 forest plots (covering 1,191 ha) and quantified tree palm (i.e., >= 10 cm diameter at breast height) abundance relative to co-occurring non-palm trees. {W}e compared the relative abundance of tree palms across biogeographical realms and tested for associations with palaeoclimate stability, current climate, edaphic conditions and metrics of forest structure. {R}esults {O}n average, the relative abundance of tree palms was more than five times larger between {N}eotropical locations and other biogeographical realms. {T}ree palms were absent in most locations outside the {N}eotropics but present in >80% of {N}eotropical locations. {T}he relative abundance of tree palms was more strongly associated with local conditions (e.g., higher mean annual precipitation, lower soil fertility, shallower water table and lower plot mean wood density) than metrics of long-term climate stability. {L}ife-form diversity also influenced the patterns; palm assemblages outside the {N}eotropics comprise many non-tree (e.g., climbing) palms. {F}inally, we show that tree palms can influence estimates of above-ground biomass, but the magnitude and direction of the effect require additional work. {C}onclusions {T}ree palms are not only quintessentially tropical, but they are also overwhelmingly {N}eotropical. {F}uture work to understand the contributions of tree palms to biomass estimates and carbon cycling will be particularly crucial in {N}eotropical forests.},
