Green Turtle Feeding on Terrestrial Leaves Reveals Energy Pathway From Land to Sea. [PDF]

Ecol Evol
We report on an adult male green turtle (Chelonia mydas) feeding on fallen leaves from a terrestrial tree, frangipani (Plumeria rubra), in the waters of Cabuyal in northern Costa Rica. This observation suggests that male turtles may feed during reproductive periods and illustrates a novel pathway for the transfer of energy from land to sea.

Maternal negative affect moderates behavioral and physiological synchrony in Latinx and Black mother–child dyads

Developmental Psychobiology, Volume 65, Issue 5, July 2023., 2023
