CONSIDERAÇÕES SOBRE A ZONA HIPORREICA NA INTERAÇÃO ÁGUA SUPERFICIAL – ÁGUA SUBTERRÂNEA

Revista Águas Subterrâneas, 2011
O conhecimento das interações entre água superficial e água subterrânea devem ser exploradas no intuito de entender suas interligações, já que, a taxa de recarga e a qualidade da água subterrânea dependem fortemente dos mananciais de superfície.

Estudio de la fracción de materia orgánica de mayor remoción en el proceso de coagulación-floculación usando agua superficial

Nexo, 2011
In this work, we performed the separation of natural organic matter (MON) present in the raw water that supplies two water treatment plants, one from river (Boaco) and one from lake (Juigalpa), in two types: hydrophobic, formed by the fractions very ...

Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Evaluating the sustainability of mineral water consumption using multi‐scale hydrogeophysics in Caxambu, Brazil

Near Surface Geophysics, Volume 24, Issue 3, Page 234-251, June 2026.
Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
