Evaluating the role of seagrass in Cenozoic CO2 variations [PDF]

open access: yes, 2016
Marine seagrass angiosperms play an important role in carbon sequestration, removing carbon dioxide from the atmosphere and binding it as organic matter. Carbon is stored in the plants themselves, but also in the sediments both in inorganic and organic

Combined Effects of Land‐Use‐ and Climate‐Driven Stressors on Stream Fungi and Organic Matter Decomposition

open access: yesFreshwater Biology, Volume 71, Issue 5, May 2026.
ABSTRACT Freshwater microbial communities sustain ecosystem functions and services, with aquatic fungi playing a key role in organic matter decomposition and nutrient transfer. However, the combined effects of multiple stressors on stream fungal biodiversity and functioning remain poorly understood.

Response of marine and freshwater algae to nitric acid and elevated carbon dioxide levels simulating environmental effects of bolide impact [PDF]

open access: yes
One of the intriguing facets of the Cretaceous-Tertiary extinction is the apparently selective pattern of mortality amongst taxa. Some groups of organisms were severely affected and some remained relatively unscathed as they went through the K/T boundary.

Palaeoecology of corals and stromatoporoids in a late Silurian biostrome in Estonia [PDF]

open access: yes, 2014
A middle Ludlow biostrome at Katri, western Estonia, the richest accumulation of corals and stromatoporoids in Estonia, is partly exposed in a coastal section ca. 1 m high, 150 m long. The fully marine biostrome consists of 5 layers of skeletal carbonate,

Chamber‐by‐Chamber Measurements of Planktonic Foraminiferal Mg, Sr, and Na to Ca Ratios With Femtosecond LA‐ICP‐MS

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

DISTRIBUITION OF CRUSTOSE CORALLINE ALGAE (CORALLINALES, RHODOPHYTA) IN THE ABROLHOS REEFS, BAHIA, BRAZIL

open access: yesRodriguésia
The crustose coralline algae have an important structural role in coral reef crests, as observed for some Atlantic reefs. In this work the distribution and abundance of crustose coralline algae and their relation to other benthic reef organisms were ...

Impacto de depredadores y niveles de recursos sobre rasgos fisiológicos de Fissurella crassa (Archeogastropoda [PDF]

open access: yes, 2015
Indexación: Web of Science; RedalycThe effects of predators on the density of prey and their resources have been widely studied; however, there is little evidence on the effects of the predators in conjunction with the availability of resources on the ...
