Influence of coral and algal exudates on microbially mediated reef metabolism. [PDF]

, 2013
Benthic primary producers in tropical reef ecosystems can alter biogeochemical cycling and microbial processes in the surrounding seawater. In order to quantify these influences, we measured rates of photosynthesis, respiration, and dissolved organic ...

Catchment Influences on Carbon Stable Isotope Variation in Trout; Might It Be Methane?

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Trout stable carbon isotope values vary significantly and appear to relate to catchment characteristics. Low carbon stable isotope values are linked to catchments with low drainage soil and high cover of pasture land use. This is likely to be linked to high levels of methane‐derived carbon entering the stream food web.

Calcareous algae of the Visean-Serpukhovian boundary beds in the Izyayu River section (south of the Chernyshev Uplift) [PDF]

Нефтегазовая геология: Теория и практика, 2023
We consider changes in the composition of the algaflora in the Visean-Serpukhovian boundary interval in the Izyayu River section. A transgressive trend in changing sedimentation conditions - from extremely shallow water at the end of the Visean to ...

Effects of reduced dissolved oxygen concentrations on physiology and fluorescence of hermatypic corals and benthic algae. [PDF]

, 2014
While shifts from coral to seaweed dominance have become increasingly common on coral reefs and factors triggering these shifts successively identified, the primary mechanisms involved in coral-algae interactions remain unclear. Amongst various potential

Hydromagnesite Precipitation in an Ultramafic‐Hosted Alkaline Lake: Insights From Lake Salda for Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Observations on aerophytic cyanobacteria and algae from ten caves in the Ojców National Park

Acta Agrobotanica, 2013
This study, carried out in 2010–11, focuses on species composition and distribution of cyanobacterial and algal communities colonizing ten caves (Biała, Ciemna, Koziarnia, Krakowska, Łokietka, Okopy Wielka Dolna, Sąspowska, Sypialnia, Zbójecka and ...

Calcite covering of sediment as a possible way of curbing blue-green algae [PDF]

, 1992
Natural calcite precipitation in lakes is a well-known control mechanism of eutrophication. In hard-water lakes, calcite deposits on the flat bottoms of shallow lakes and near the shores of deeper lakes resulted from biogenic decalcification during the ...

Depositional Setting of Eastern Sakarya Zone (NE Türkiye): Late Cretaceous–Paleogene Period Biostratigraphy, Sedimentology and Tectono‐Sedimentary Basin Evolution

Basin Research, Volume 38, Issue 3, May–June 2026.
K‐Pg transition and Maastrichtian stage of sedimentary basin evolution of the Eastern Sakarya Zone. ABSTRACT This study reconstructs the late Campanian–Thanetian tectonic and sedimentary evolution of the Eastern Sakarya Zone Basin (Türkiye) during the closure of the Neotethys Ocean, through the integration of tectonic, biostratigraphic and sedimentary ...

Shallow-water carbonate facies herald the onset of the Palaeocene-Eocene Thermal Maximum (Hazara basin, Northern Pakistan)

Journal of Asian Earth Sciences: X
We investigate the Palaeocene succession of the Hazara Basin (Northern Pakistan) to better understand the impact of climate change on marine carbonate-producing organisms.

Colonization, Growth and Productivity of Crustose Coralline Algae in Sunlit Reefs in the Atlantic Southernmost Coral Reef

Frontiers in Marine Science, 2019
One of the most important contributions of crustose coralline algae (CCA) to some coral reefs is their structural role in sunlit habitats, but in the Atlantic southernmost coral reef, Abrolhos, these algae are also important components of living ...
