Methane and Nitrous Oxide Reshape the Air‐Water Greenhouse Gas Budget of a Tropical Estuarine Delta

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Estuaries are important sources and sinks of greenhouse gases (GHGs), yet assessments of their radiative balance often focus primarily on carbon dioxide (CO2), with less attention given to methane (CH4) and nitrous oxide (N2O). We combine measurements of CH4 and N2O air‐water fluxes with concurrent CO2 data in a tropical estuarine delta ...

Preservation Factors during Cretaceous Oceanic Anoxic Events in the Espírito Santo Basin, Southeast Brazil

open access: yesGeosciences, 2022
The oceanic anoxic events (OAEs) are characterized by enhanced accumulation of organic matter in marine sediments. However, there is still an ongoing debate regarding the interplay between production and preservation during these events.

Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Caracterización geoquímica de la ruptura sedimentaria entre los yesos de la unidad salina e intermedia de la cuenca de Madrid

open access: yesEstudios Geologicos, 1989
En el Terciario de la Cuenca de Madrid existen dos unidades sedimentarias de carácter yesífero. Ambas unidades están constituidas por yesos con diferentes características, aunque su separación es dificil en diversos afloramientos debido a intensos ...

Probiotics mitigate thermal stress- and pathogen-driven impacts on coral skeleton

open access: yesFrontiers in Marine Science, 2023
Threats leading to a reduction in coral populations are apparent worldwide. Several different approaches have been tested to accelerate the adaptation of corals to a changing climate. Here, we evaluated the skeleton structure, crystal habit, and chemical

Bromelicolous Habit and Phoresy of Ostracoda in a Species of Treefrog From the Brazilian Cerrado

open access: yesAustral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Some plants develop phytotelmata, specialized structures that retain water and form small aquatic ecosystems harbouring diverse organisms. Bromeliads (Bromeliaceae) are classic examples, as their leaf axils provide suitable habitats for bacteria, algae, protozoa, invertebrates and vertebrates, including anurans.

Consistent Microbial Assembly in the Rhizosphere of Crop Wild Progenitors

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 4, April 2026.
ABSTRACT Aim Microbiome rewilding seeks to harness plant‐microbe interactions for sustainable agriculture, assuming that ancestral microbial partners have been lost during domestication and geographical spread. Designing microbiome rewilding strategies requires a quantitative and predictive understanding of the fundamental ecological processes ...

Autoorganización geoquímica: una alternativa sinergética en la modelización de sistemas geológicos. Revisión de principios básicos

open access: yesEstudios Geologicos, 1989
La autoorganización geoquímica es el reflejo de la aplicación de una Ciencia más amplia, la Sinergética, al campo de la Geología. Se trata de una línea de investigación abierta muy recientemente y, por tanto, su planteamiento se encuentra todavía ...
