Effects of beach remourishment on the benthic macrofauna and the fishes of the nearshore zone at Sebastian Inlet State Recreation Area [PDF]

, 1987
Approximately 100,000 cubic yards of sand was transported to the ocean beach to renourish the eroded beach front during the period December 1985 through May 1986.

Measuring Complexity in an Aquatic Ecosystem

, 2013
We apply formal measures of emergence, self-organization, homeostasis, autopoiesis and complexity to an aquatic ecosystem; in particular to the physiochemical component of an Arctic lake. These measures are based on information theory.

The last glacial-interglacial cycle in Lake Ohrid (Macedonia/Albania): testing diatom response to climate [PDF]

, 2010
Lake Ohrid is a site of global importance for palaeoclimate research. This study presents results of diatom analysis of a ca. 136 ka sequence, Co1202, from the northeast of the lake basin.

Effect of acidification on leaf litter decomposition in benthic and hyporheic zones of woodland streams [PDF]

Water Research, 2012
Anthropogenic acidification has deleterious effects on both structure and functioning of surface water ecosystems. This study examined how it may affect the leaf decomposition rate and the community structure and activity of decomposers in both benthic and hyporheic zones of five headwater streams along an acidification gradient from highly acidic (pH ...

Microbialite cathodoluminescence: A tool for investigating palaeoredox conditions, alteration histories and primary textures across time

The Depositional Record, EarlyView.
Microbialites are common throughout the rock record and key to our understanding of Earth history, yet a relatively common microscopy technique—cathodoluminescence (CL)—has not previously been leveraged to understand them. In this contribution, we examine microbialites of varying ages (modern to Proterozoic) with CL and report on the patterns and ...

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

An ecological and methodological assessment of benthic gross primary production in northern lakes

Ecosphere, 2022
Benthic gross primary production (GPP) is often the most important part of aquatic food webs in northern lakes, which are gradually warming and receiving increased terrestrial colored dissolved organic carbon loadings due to global change.

The control of hydrogen sulfide on benthic iron and cadmium fluxes in the oxygen minimum zone off Peru [PDF]

Biogeosciences, 2020
Sediments in oxygen-depleted marine environments can be an important sink or source of bio-essential trace metals in the ocean. However, the key mechanisms controlling the release from or burial of trace metals in sediments are not exactly understood ...

Carbonate microfacies and transgressive‐regressive sequences of Oxfordian shallow‐water limestones (Korallenoolith, Lower Saxony Basin)

The Depositional Record, EarlyView.
The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

Assessing pressure drivers on the benthic ecosystem in the coastal zone of Western Messinia, Greece

Estuarine, Coastal and Shelf Science, 2022
The Messinia region, located in the South – West of the Peloponnese, Greece, is an ecologically valuable area comprising of several important coastal habitats (including coastal lagoons, seagrass meadows, and Mediterranean rhodolith beds) eliciting its inclusion in the Natura 2000 network.
