Weedy Seadragon genomics reveal highly distinct populations

Charismatic, iconic and Instagram-friendly, the weedy seadragon is a favourite with divers and snorkellers. The first genomic study of east coast Australian seadragon populations can now reveal “weedies” from NSW, Victoria and Tasmania are significantly different. The study, published in PLOS ONE, also reveals that Victorian weedy seadragons may form a subspecies which has […]

The University of Reading led an international team of scientists in considering the effect of brain size for the first […]

Dynamic risk management in cell populations

Dynamic risk management by cell populations. In the absence of environmental signals, uncertainty about the environment is high (middle panel) and the population of E. coli cells were found to demonstrate strong diversity in their sensory response (indicated by broad distribution of response coefficient K_(1/2) in lower panel), enabling responses to many different signals (schematized […]

How air pollution affects homeless populations — ScienceDaily

When air quality worsens, either from the smoke and ozone of summer or the inversion of winter, most of us stay indoors. But for individuals experiencing homelessness, that’s not always an option. In a new study, researchers from the University of Utah document the effect of air pollution on people experiencing homelessness, finding that nearly […]

Bark beetle outbreaks benefit wild bee populations, habitat — ScienceDaily

When southern Rocky Mountain forests are viewed from a distance these days, it may not look like much is left. Large swaths of dead, standing Engelmann spruce trees tell the tale of a severe regional spruce beetle epidemic in its waning stages. But among those dead trees, researchers have found good news. Zoom-in to the […]
