Remoção da citotoxicidade no ensaio de atividade estrogênica (YES) para amostras de sedimento lagunar: Métodos de extração e efeito matriz [PDF]

open access: yesRevista DAE, 2023
A poluição de sistemas aquáticos com contaminantes emergentes é uma crescente preocupação. Dentre estes, os desreguladores endócrinos (DE) são substâncias que podem alterar o sistema endócrino de seres vivos até em baixas concentrações.

Quantification of red soil macropores affected by slope erosion and sediment using computed tomography

open access: yesVadose Zone Journal, Volume 22, Issue 6, November/December 2023., 2023
Abstract Soil structure is an important factor interacting with soil erosion and sediment processes. However, few studies have focused on the relationship between soil macroporosity and soil erosion across different terrains. The aim of this study was to quantify and compare soil properties and macroporosity characteristics in collapsing gully areas ...

Long‐term hydrological and biogeochemical datasets from a Mediterranean forest site (Montseny, NE Spain)

open access: yesHydrological Processes, Volume 37, Issue 5, May 2023., 2023
Hydrological and biogeochemical datasets made available in the Zenodo platform for two catchments in Montseny (Catalonia, Spain) for the period 1978–2018. Abstract We present here, and make freely available, two long‐term datasets on the hydrology and hydrochemistry of two small catchments totally or partially covered by holm oak (Quercus ilex) forests.

Digitizing the coral reef: Machine learning of underwater spectral images enables dense taxonomic mapping of benthic habitats

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 2, Page 596-613, February 2023., 2023
Abstract Coral reefs are the most biodiverse marine ecosystems, and host a wide range of taxonomic diversity in a complex spatial community structure. Existing coral reef survey methods struggle to accurately capture the taxonomic detail within the complex spatial structure of benthic communities.

Meta‐analysis of ecosystem services associated with oyster restoration

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Restoration of foundation species promises to reverse environmental degradation and return lost ecosystem services, but a lack of standardized evaluation across projects limits understanding of recovery, especially in marine systems. Oyster reefs are restored to reverse massive global declines and reclaim valuable ecosystem services, but the ...

Amphibian loss alters periphyton structure and invertebrate growth in montane streams

open access: yesJournal of Animal Ecology, Volume 91, Issue 11, Page 2329-2337, November 2022., 2022
This paper demonstrates that amphibian loss increases periphyton biomass, causes shifts in algal assemblages and reduces invertebrate growth. It highlights the importance of protecting amphibians in order to maintain normal stream ecosystem functioning, especially in nonforested streams where periphyton in the main energy resource.

Prioritizing forest management actions to benefit marine habitats in data‐poor regions

open access: yesConservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract Land‐use change is considered one of the greatest human threats to marine ecosystems globally. Given limited resources for conservation, we adapted and scaled up a spatially explicit, linked land–sea decision support tool using open access global geospatial data sets and software to inform the prioritization of future forest management ...

Identificação de poluentes orgânicos em água, sedimento e nível trófico secundário em estuário tropical [PDF]

open access: yesRevista DAE, 2022
Poluentes orgânicos foram identificados em diferentes matrizes ambientais: água, sedimento e organismos de nível trófico secundário. A identificação ocorreu em nove sites ao longo de três zonas, durante os meses de dezembro de 2017 e junho de 2018 em ...

Assessment of Fractures in Excavation Damaged Zone around Roadways of an Iron Mine Using Optical Televiewer Detecting Method

open access: yesAdvances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
The properties of the excavation damaged zone (EDZ) are critical to the stability of the surrounding rock masses of the chamber, roadway, and dam, and fractures in the EDZ also affect the properties of the EDZ. In this paper, the fractures in the EDZ of an underground iron mine roadway were tested using borehole television (BTV).

Exposición a químicos disruptores endócrinos obesogénicos y obesidad en niños y jóvenes de origen latino o hispano en Estados Unidos y Latinoamérica: una perspectiva del curso de la vida

open access: yesObesity Reviews, Volume 22, Issue S5, Octubre 2021., 2021
Resumen En el 2019, en seguimiento a un taller dirigido por el Global Health Studies del Fogarty International Center sobre el tema de la prevención de la obesidad infantil y las sinergias de investigación que surgen a través de las colaboraciones transfronterizas, convocamos a un grupo de expertos de Estados Unidos y Latinoamérica para que realizaran ...
