Species distribution models (SDMs) are increasingly applied in conservation management
to predict suitable habitat for poorly known populations. High predictive performance of
SDMs is evident in validations performed within the model calibration area (interpolation),
but few studies have assessed SDM transferability to novel areas (extrapolation), particularly
across large spatial scales...

There is a lack of consensus regarding the roles of sulfide saturation versus volatile degassing on the partitioning of Cu and Ag during differentiation and eruption of convergent margin magmas. Because of their oxidized character, volatile-rich magmas from the Eastern Manus Back-arc Basin (EMBB) only reach sulfide saturation following magnetite-driven...
