Status of Pasil Reef Marine Sanctuary in Cogtoug Bay. Philippines

open access: yesJPAIR, 2008
The status of corals and reef fish resources inside Pasil ReeJ Marine Sanctuary in Cogtong Bay, Bohol, Philippines was surveyed using 50m Lille Intercept Transect method to obtain percent coral cover. The coral reef fish populations in the sanctuary were

Sea Ice Dynamics Drive Benthic Microbial Communities in McMurdo Sound, Antarctica

open access: yesFrontiers in Microbiology, 2021
Climate change is driving dramatic variability in sea ice dynamics, a key driver in polar marine ecosystems. Projected changes in Antarctica suggest that regional warming will force dramatic shifts in sea ice thickness and persistence, altering sea ice ...

The nitrogen isotope effect of benthic remineralization-nitrification-denitrification coupling in an estuarine environment [PDF]

open access: yes, 2011
The nitrogen (N) stable isotopic composition of pore water nitrate and total dissolved N (TDN) was measured in sediments of the St. Lawrence Estuary and the Gulf of St. Lawrence.

Habitat differences in deep-sea megafaunal communities off New Zealand: implications for vulnerability to anthropogenic disturbance and management

open access: yesFrontiers in Marine Science, 2016
Research on benthic communities in the deep sea has focused largely on habitats in isolation, with few studies considering multiple habitats simultaneously in a comparable manner. The present study aimed to determine the structural differences in benthic

Chemically Mediated Microbial “Gardening” Capacity of a Seaweed Holobiont Is Dynamic

open access: yesMicroorganisms, 2020
Terrestrial plants are known to “garden” the microbiota of their rhizosphere via released metabolites (that can attract beneficial microbes and deter pathogenic microbes). Such a “gardening” capacity is also known to be dynamic in plants.

Chilling damage to mangrove mollusk species by the 2008 cold event in Southern China

open access: yesEcosphere, 2016
The frequency, duration, and intensity of extreme cold events are widely regarded as primary constraints on the upper latitudinal limits of mangroves. Little data are available on the consequences of recovery (or lack thereof) of non‐floristic components

Impacts of land-based pollutants on water chemistry and benthic macroinvertebrates community in a coastal lagoon, Lagos, Nigeria

open access: yesScientific African, 2020
Tropical coastal waters are prone to increased influx of pollutants from land during the rains. The effects of pollution influx on the water and macrobenthic fauna of a coastal lagoon, Lagos, Nigeria were investigated.

Effects of hypoxia on benthic macrofauna and bioturbation in the Estuary and Gulf of St. Lawrence, Canada [PDF]

open access: yes, 2010
The bottom water in the 4300 m deep Lower St. Lawrence Estuary (LSLE) is persistently hypoxic in contrast to the normoxic bottom waters in the Gulf of St. Lawrence (GSL). We photographed the seabed at 11 stations in the Estuary and Gulf of St.

Classification and Mapping of Benthic Biotopes in Arctic and Sub-Arctic Norwegian Waters

open access: yesFrontiers in Marine Science, 2020
In this paper, we describe the species composition of biotopes occurring in a wide range of environments and present their geographic distribution based on results from quantitative analyses of video-records collected as part of the Norwegian seabed ...

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

open access: yesAdvanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...
