Spatial ecology of two emblematic deep-sea crustaceans in the Salas y Gomez, Nazca and Juan Fernandez ridges Southeast Pacific.

ABSTRACT: The Salas & Gómez, Nazca, and Juan Fernández ridges are among the least studied regions on the planet. Ecological knowledge of deep-sea organisms inhabiting islands and seamounts along these ridges is limited. Using various sources, including published data and in situ information from five scientific expeditions in the region, we analyzed the spatial ecology of Paromola rathbuni and Projasus bahamondei, two mobile species of benthic megafauna. Random Forest models detected different combinations of abiotic variables affecting species distribution. The distribution of P. bahamondei was primarily influenced by dissolved oxygen, longitude (W), and temperature. The distribution of P. rathbuni was mainly explained by longitude (W), followed by depth, temperature, and oxygen. Generalized Linear
