This study addresses the urgent need to understand the impacts of climate change on coastal ecosystems by demonstrating how to use the SWAT+ model to assess the effects of sea level rise (SLR) on agricultural nitrate export in a coastal watershed. Our framework for incorporating SLR in the SWAT+ model includes: (1) reclassifying current land uses to water for areas with elevations below 0.3 m based on SLR projections for mid-century; (2) creating new SLR-influenced land uses, SLR-influenced crop database, and hydrological response units for areas with elevations below 2.

Evaluating the forthcoming impacts of climate change is important for formulating efficient and flexible approaches to water resource management. General Circulation Models (GCMs) are primary tools that enable scientists to study both past and potential future climate changes, as well as their impacts on policies and actions. In this work, we quantify the future projected impacts of hydroclimatic extremes on the coastal, risk-prone Tar-Pamlico River basin in North Carolina using GCMs from the Sixth International Coupled Model Intercomparison Project (CMIP6).

Article Synopsis
  • Trypanosoma cruzi, a parasite reliant on heme, regulates its heme levels by adjusting the expression of a specific protein called TcHRG when exposed to free heme in culture.
  • The study found that TcHRG responds similarly to both bound (hemoglobin) and free heme, located near the flagellar pocket and mitochondria.
  • Interestingly, despite the absence of endocytosis, parasites can still acquire heme from hemoglobin, suggesting that TcHRG plays a key role in breaking down hemoglobin to extract heme from outside the cell through the flagellar pocket.

is a zoonotic protist pathogen that infects up to one third of the human population. This apicomplexan parasite contains three genome sequences: nuclear (65 Mb); plastid organellar, ptDNA (35 kb); and mitochondrial organellar, mtDNA (5.9 kb of non-repetitive sequence).
