Shifting in the shadows: Morphofunctional variations of Miconia sellowiana Naudin (Melastomataceae) associated with cave environments. [PDF]
Cave environments filter plant traits, selecting thinner, smaller leaves with reduced photosynthetic and vascular structures. Abstract Caves present unique ecological conditions that influence the distribution and adaptation of species, yet studies on cave‐associated vegetation remain limited.

Assessment of hybrid geoids in Chile and Spain, combining GGM and GNSS/Leveling observations
This research presents the results for analyses done to five geopotential global models (GGM), comparing them with ground data from GNSS and leveling in heterogenic zones from the geodetic perspective, in Chile and Spain.
