  abstract = {{L}arge tropical trees are rightly perceived as supporting a plethora of organisms. {H}owever, baseline data about the variety of taxa coexisting on single large tropical trees are lacking and prevent a full understanding of both the magnitude of biodiversity and the complexity of interactions among organisms in tropical rainforests. {T}he two main aims of the research program "{L}ife on {T}rees" ({LOT}) are (1) to establish baseline knowledge on the number of eukaryote species supported/hosted by the above-ground part of a single tropical tree and (2) to understand how these communities of organisms are assembled and distributed on or inside the tree. {T}o achieve the first goal, we integrated a set of 36 methods for comprehensively sampling eukaryotes (plants, fungi, animals, protists) present on a tropical tree. {T}he resulting {LOT} protocol was conceived and implemented during projects in the {A}ndean {A}mazon region and is proposed here as a guideline for future projects of a similar nature. {T}o address the second objective, we evaluated the microclimatic differences between tree zones and tested state-of-the-art terrestrial laser scanning ({TLS}) and positioning technologies incorporating satellite and fixed base station signals (d{GNSS}). {A} marked variation in temperature and relative humidity was detected along a 6-zones {J}ohansson scheme, a tree structure subdivision system commonly used to study the stratification of epiphytic plants. {S}amples were collected from these six zones, including three along the trunk and three in the canopy. {T}o better understand how different tree components (e.g., bark, leaves, fruits, flowers, dead wood) contribute to overall tree biodiversity, we categorized observations into communities based on {J}ohansson zones and microhabitats. {TLS} was an essential aid in understanding the complex tree architecture. {B}y contrast, the accuracy of positioning samples in the tree with d{GNSS} was low. {C}omprehensively sampling the biota of individual trees offers an alternative to assessing the biodiversity of fewer groups of organisms at the forest scale. {L}arge old tropical trees provide a wealth of microhabitats that encompass a wide range of ecological conditions, thereby capturing a broad spectrum of biodiversity.},
