Popis: | Vegetated areas such as seagrass beds provide food and essential habitat for many fish and invertebrate species. In particular, many economically important fishes depend on seagrass beds as nursery grounds. In recent decades, there has been a rapid decline in seagrass coverage due to the development of coastal areas worldwide, altering these ecosystems and their community structure. Within Tampa Bay (Florida’s largest estuary), seagrass coverage and water quality underwent a decline followed by a recovery over the past three decades; these changes may have altered the community structure of seagrass-associated fauna. We examined the diets of juvenile Spotted Seatrout Cynoscion nebulosus, a common estuarine predator, to assess whether documented changes in water quality and habitat were reflected in their trophodynamics. Stomach contents of Spotted Seatrout from Tampa Bay were sampled during three different studies conducted in 1981–1982, 1991–1992, and 2005–2013. We analyzed data from these studie... |
