Total obliteration of kinematically produced aqueous primary structures is consistent with high aerobic levels in the water column and within the upper part of the sedimentary column as attested by the rich epifauna (Brenchley and Harper, 1998).
The objectives of this project were to determine if: 1) bioaccumulation of copper, cadmium, and lead occurs in seagrass, epiphytes, and epifauna, 2) metal levels are higher in samples from a more impacted site, and 3) trophic transfer of copper occurs from epiphytes to snails in the laboratory.
How many of the following can you define: epifauna, sesile, crevices, infauna, substrate, planktonic, lecithotrophic, demersal, foraminiferan protozoans, macrofauna, meiofauna, abyssal plain, continental shelf, oscillate, flotsam and jetsam.
During the winter and early spring, seaweed assemblages on hard substrata support very high densities of mobile epifauna, dominated by the suspension-feeding amphipods Caprella penantis and Jassa marmorata (formerly J.
The rapid response of macrocrustacean epifauna to a bloom-forming planktonic diatom shows an unexpectedly strong coupling of planktonic primary production to benthic secondary production.
Measurements of short-term turnover of epifauna within seagrass beds using an in situ staining method.
I removed encrusting algae and epifauna from coral samples before freezing them in liquid nitrogen in the field.
Otra alternativa para el estudio de estas comunidades son los experimentos de campo en los cuales, a traves del establecimiento de diferentes substratos artificiales que semejan las raices del mangle rojo, se abordan temas de interes tales como la colonizacion y la sucesion por la epifauna.
Predator exclusion nets have been found to create a "reef effect" by enhancing abundance of both macroalgae and epifauna (Powers et al.
In southern Brazil, spawning occur also from spring to summer (Haimovici & Ignacio, 2005) in coastal waters and pelagic eggs and larvae are carried passively into the Patos Lagoon Estuary (PLE) where they recruit to the bottom with 20-30 mm total length (Weiss, 1981) and feed actively on infauna and epifauna as juveniles (Goncalves et al.
The effects of these newly arrived, specialized, fast-growing predators will then gradually ripple through the benthic epifauna, altering species interactions and potentially changing community composition as they consume large patches of their prey, some of which, such as sponges, can be very long-lived.
