Beyond cichlid diversification: environmental drivers of biodiversity across the Nicaraguan lake system

Abstract The Nicaraguan lake system, comprising two Great Lakes and several isolated crater lakes, is a natural laboratory for investigating how environmental heterogeneity and isolation shape biodiversity and a classic model for Midas cichlid diversification. We asked whether la...

Phagocytosis of microbial symbionts supports embryonic nutrition in the sponge Halichondria panicea

Abstract Animals associate with microbial symbionts that play crucial roles in their nutrition and development, yet their function during gametogenesis and embryogenesis remains poorly understood. Here, we investigate host–symbiont dynamics throughout the reproductive cycle of th...
