Residence time (τ) is the average amount of time that particles spend in an ecosystem. Often estimated from the ratio of volume to flow rate, τ equates the physical environment with dynamics of growth. Here, we propose that τ is key to understanding relationships...

The adaptative bleaching hypothesis (ABH) states that, depending on the symbiotic flexibility of coral hosts (i.e., the ability of corals to “switch” or “shuffle” their algal symbionts), coral bleaching can lead to a change in the composition of their associated...

Mesophotic coral ecosystems (MCEs, reefs 30–150 m) are understudied, yet the limited research conducted has been biased towards large sessile taxa, such as scleractinian corals and sponges, or mobile taxa such as fishes. Here we investigate zooplankton communities...
