Abstract Reproduction is a fundamental biological process for the survival and continuity of species. Examining changes in reproductive strategies offers valuable insights into how animals have adapted their life histories to different environments. Since reproduction one most energy-intensive processes female animals, nutrient scarcity expected interfere with ability invest gametes. Lately, new model study adaptation limitation has emerged; Mexican tetra Astyanax mexicanus . This fish species exists as two morphs, surface river morph cave-dwelling morph. The dark, biodiversity, nutrient-limited cave environment consequently evolved an impressive starvation resistance. However, limitations this remains poorly understood. Here, we compared breeding activities maternal contributions between laboratory-raised cavefish. We found that cavefish produce clutch sizes eggs larger yolk fish, indicating greater deposition embryos. To systematically characterize compositions, used untargeted proteomics lipidomics approaches analyze protein lipid profiles 2-cell stage embryos increased proportion sphingolipids fish. Additionally, generated transcriptomic ovaries using combination single cell bulk RNA sequencing examine differences contribution. genes essential hormone regulation were upregulated follicular somatic cells evaluate whether these contribute abilities under natural-occurring stress, induced starved Remarkably, maintained breed starvation, whereas largely lost ability. identified insulin-like growth factor 1a receptor ( igf1ra ) potential candidate gene mediating downregulation ovarian development genes, potentially contributing starvation-resistant fertility Taken together, investigated , which will provide adaptations environments extreme deficit.

The ecological and genetic changes that underlie the evolution of host-microbe interactions remain elusive, primarily due to challenges in disentangling variables alter microbiome composition. To understand impact host habitat, genetics, evolutionary history on microbial community structure, we examined gut microbiomes river- three cave-adapted morphotypes Mexican tetra,
