about the species
Megalorchestia californiana, the long-horned beach hopper, is a terrestrial amphipod found along sandy beaches of the California coast. It occupies the upper intertidal and supratidal zones, where it feeds on stranded kelp and other organic debris, contributing to nutrient transfer between marine and terrestrial systems. This species is adapted to dynamic coastal environments and is sensitive to beach disturbance, making it an important component of California’s sandy beach ecosystems.
why species was selected
This species was selected because it is widespread along the California coast and closely tied to beach ecosystem function. Its limited dispersal and sensitivity to habitat alteration make it valuable for assessing population connectivity and genetic responses to coastal development, recreation, and climate-driven shoreline change.
