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 ...

Abstract The biogeochemical fate of terrestrial dissolved organic carbon (tDOC) in aquatic environments is a poorly understood part of the carbon cycle. In nature, tDOC undergoes photochemical and microbial degradation simultaneously. However, photochemical and microbial degradation are generally quantified separately, and nonlinear interactions ...

Effects of Silvopasture Establishment on Aqueous and Gaseous Soil N Losses at the University of New Hampshire Organic Dairy Research Farm [PDF]
The expansion of local agriculture in the New England region is putting increased pressure on farmers to expand their arable land base. While clear-cutting is a traditional method of converting forested land to agriculture, it is known for having ...

Abstract All organisms contain carbon, nitrogen, and phosphorus in widely ranging amounts and proportions. Integrating existing datasets enables quantification of this variation at global scales. Such efforts could leverage ecological stoichiometry theory, the study of elemental supply and imbalances in ecological interactions, to connect ecological ...

Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

This article analyses future projections of ocean properties for a region of the south‐west Pacific Ocean encompassing the New Zealand Exclusive Economic Zone under different climate change emission scenarios. Projections are updated and expanded from previous assessments using a “best” ensemble comprising both CMIP5 and CMIP6 earth system models.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Potential Impacts of Climate Interventions on Marine Ecosystems
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...
