ABSTRACT Copepods are one of the most abundant invertebrate groups in seas and oceans a significant food source for marine animals. also particularly sensitive to elevated temperatures. However, it is relatively unknown how internal microbiome influences copepod susceptibility warming. We addressed this fundamental knowledge gap by assessing key life history traits (survival, development, reproduction) changes tropical calanoid Acartia sp. response warming (26°C, 30°C, 34°C). Copepod microbiomes were analyzed using high throughput DNA sequencing V1–V9 16S rRNA hypervariable regions. performance was better at 30°C than 26°C, as indicated faster higher growth rate, fecundity. these parameters strongly decreased 34°C. recorded 1,262,987 amplicon sequence reads, corresponding 392 total operational taxonomic units (OTUs) 97% similarity. Warming did not affect OTU numbers biodiversity indices, but substantially changed relative abundance three major phyla: Proteobacteria, Actinobacteria, Bacteroidota. The thermophilic opportunistic Proteobacteria Bacteroidota increased under extreme temperatures (34°C) while Actinobacteria reduced. Changes bacteria might be related reduced growth, survival, reproduction Profiling functional role all bacterial temperature change will fundamentally advance our mechanistic understanding copepods and, more generally, invertebrates climate.
