Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.Abstract We investigated temporal changes in operational Fe pools and their association with soil organic carbon (SOC) fractions in an estuarine soil affected by the deposition of iron‐rich mine tailings over 6 years in Southeast Brazil. Sequential Fe extractions revealed a 56% decrease in Fe extracted with citrate–bicarbonate–dithionite alongside a 50%

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.Habitat complexity and grazing by invertebrate molluscs shaped community structure and ecosystem functioning on eco‐engineered substrates through distinct mechanisms. Increasing structural complexity increased invertebrate species richness with limited effects on macroalgae and carbon flux, while grazer exclusion had strong effects on macroalgal ...

Survival and Behavior of Amphibians in a Seasonally Flooded Tropical Forest
Biotropica, Volume 58, Issue 4, July 2026.How do tropical amphibians survive seasonal flooding? A three‐year capture–mark–recapture study in Costa Rica revealed species‐specific responses to flood events, with flooding reducing apparent survival in some species while others persisted through behavioral adaptations and use of arboreal refugia.

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Coupling landscapes and river flows to restore highly modified rivers
Water Resources Research, 2019 Modifications to landscapes and flow regimes of rivers have altered the function, biodiversity, and productivity of freshwater ecosystems globally. Reestablishing geomorphological and hydrological conditions necessary to sustain ecosystems is a central ...

Impacts of the 2014 severe drought on the Microcystis bloom in San Francisco Estuary
Harmful Algae, 2017 The increased frequency and intensity of drought with climate change may cause an increase in the magnitude and toxicity of freshwater cyanobacteria harmful algal blooms (CHABs), including Microcystis blooms, in San Francisco Estuary, California. As the fourth driest year on record in San Francisco Estuary, the 2014 drought provided an opportunity to ...

Trends in the Sediment Yield of the Sacramento River, California, 1957–2001
San Francisco Estuary and Watershed Science, 2004 Human activities within a watershed, such as agriculture, urbanization, and dam building, may affect the sediment yield from the watershed. Because the equilibrium geomorphic form of an estuary is dependent in part on the sediment supply from the ...

Predicting Sediment Bulk Density for San Francisco Estuary
San Francisco Estuary and Watershed ScienceSediment bulk density (ρdry) and particle size are two important parameters for predicting sediment bed erosion. ρdry, however, is difficult to measure accurately. The units of ρdry have not been consistently reported in the literature, leading to confusion, particularly in the calculation of sediment budgets that typically require integrating mass ...
