Extensive transcriptional variation poses a challenge to thermal stress biomarker development for endangered corals.

abstract：:Facilitated by the intensification of global trading, the introduction and dispersal of species to areas in which they are historically non-native is nowadays common. From an evolutionary standpoint, invasions are paradoxical: not only non-native environments could be different from native ones for which introduced in...
