Prey selectivity by juvenile Atlantic cod Gadus morhua in three coastal habitat types. / Ljungberg, Peter; Nilsson, Anders; Persson, Anders.. In: Marine Ecology Northwest Atlantic eelgrass meadows are also home to predatory native and invasive crab species (Able et al., 2002; Garbary et al., 2014; Neckles, 2015; Matheson et al., 2016). We investigated the possibility that crabs can prey on Gonionemus, and the potential impact of Gonionemus prey on crab predators.

Juvenile Chum salmon and juvenile Chinook Predator–prey interactions in a restored eelgrass ecosystem: strategies for maximizing success of reintroduced bay scallops (Argopecten irradians) Eelgrass has thick, creeping rhizomes with many roots and nodes. Predators. Migratory waterfowl such as brants, redheads, widgeons, black ducks and Canada geese feed on eelgrass, as do green turtles. Although they do not feed on eelgrass, cownose rays destroy eelgrass beds in many areas as they root through bottom sediments for their prey.

Eelgrass is one of the world's most widespread marine macrophytes and grows in coastal locations around the northern hemisphere including our study location, San Diego Bay, CA, USA. are limited. We surveyed predation intensity on common prey (live amphipods and gastropods) in communities of eelgrass (Zostera marina) at 48 sites across its Northern Hemisphere range, encompassing over 37° of latitude and four continental coastlines. Eelgrass (Zostera marina) is a key foundation species in estuaries and coastal seas across the northern hemisphere (30° to 67° latitude), and thus provides a unique opportunity to test latitudinal gradients in ecological processes within communities of a single habitat‐forming species, minimizing potential confounding factors in prior biogeographic studies.
