Article Synopsis
- Global rates of biological invasion are rising, negatively impacting native biodiversity and ecosystem services, and hybridization may enhance this by increasing genetic variation and fitness in invasive species.
- The study focused on blowflies in New Zealand, which are believed to have invaded from Australia between 1779 and 1841, analyzing genome-wide SNPs from 154 individuals across 24 populations to assess gene flow and hybridization.
- Results indicated weak genetic structure in New Zealand populations, suggesting high gene flow, with evidence of both interspecific hybridization between species and intraspecific admixture among populations, underscoring the significance of hybridization in the context of biological invasions.
Municipal biosolids are a nitrogen (N)-rich agricultural fertilizer which may emit nitrous oxide (NO) after rainfall events. Due to sparse empirical data, there is a lack of biosolids-specific NO emission factors to determine how land-applied biosolids contribute to the national greenhouse gas inventory. This study estimated NO emissions from biosolids-amended land in Canada using Tier 1, Tier 2 (Canadian), and Tier 3 (Denitrification and Decomposition model [DNDC]) methodologies recommended by the Intergovernmental Panel on Climate Change (IPCC).

Unlike Canada's commercially managed forests that have a long history of inventory and modelling tools, there is both a lack of coordinated data and considerable uncertainty on assessment procedures for urban forest carbon. Nonetheless, independent studies have been carried out across Canada.

A previous study at five Ontario municipal wastewater treatment plants (WWTPs) confirmed that enteric viruses are less susceptible to disinfection than E.

- The study aimed to evaluate the effectiveness of the ED Senior Abuse Identification (ED Senior AID) tool in identifying elder abuse during emergency department visits.
- Researchers conducted the study in three U.S. emergency departments with 916 participants aged 65 and older and used a combination of assessments and expert panel evaluations to confirm cases of abuse.
- Results showed that the ED Senior AID tool had a sensitivity of 94.1% and specificity of 84.3%, indicating it is a reliable screening method for identifying elder abuse, despite some variability in confidence intervals.
