Human perturbations to mercury in global rivers Human perturbations to mercury in global rivers
Mercury compounds are potent neurotoxins that pose threats to human health, primarily through fish consumption. Rivers, critical for drinking water and food supply, have seen rapid increases in mercury concentrations and export to coastal margins since the Industrial Revolution (~1850). However, patterns of these changes remain understudied, limiting assessments of environmental policies...
Shotgun sequencing of airborne eDNA achieves rapid assessment of whole biomes, population genetics and genomic variation Shotgun sequencing of airborne eDNA achieves rapid assessment of whole biomes, population genetics and genomic variation
Biodiversity and its associated genetic diversity are being lost at an unprecedented rate. Simultaneously, the distributions of flora, fauna, fungi, microbes and pathogens are rapidly changing. Novel technology can help to capture and record genetic diversity before it is lost and to measure population shifts and pathogen distributions. Here we report the rapid application of shotgun...
Interpreting a sudden population decline in a long-lived species (Malaclemys terrapin rhizophorarum) Interpreting a sudden population decline in a long-lived species (Malaclemys terrapin rhizophorarum)
Long-term ecological studies are critical for providing insight into population dynamics and detecting population declines, particularly for species of conservation concern. However, spatiotemporal variation and logistical challenges make the identification of sudden population declines difficult. We conducted an in-water capture-mark-recapture study of mangrove diamond-backed terrapins...
