Early identification can also help improving language outcomes. This first life-history characteristics study of the great hammerhead shark in the central Pacific Ocean suggests that water temperature, the increased presence of prey, but also the lunar cycle may have an influence on hammerhead shark aggregation in the southern Pacific.Īrticle link: Hearing loss negatively impacts children’s language outcomesĭetecting hearing loss in newborns within the first few weeks of life is vital to facilitating early interventions such as amplification devices. The sharks spent around six days a month there for up to five months. They published their results in Frontiers in Marine Science.ĭuring the austral summer months of 20, the researchers observed 55 individuals, all but one of them female, flock to the atoll, representing an unprecedented number. Now, an international team of researchers gained first insights into population characteristics and seasonal occurrence of the sharks in the western Tuamotu archipelago in the southern Pacific Ocean. This region, due to its largely pristine environment, provides a unique opportunity to study shark behavior. Great hammerhead sharks are a highly mobile species, yet little is known about their occurrence and seasonality in the central Pacific Ocean. These findings suggest that the microbial community of grapevines plays a critical role in the expression of the GTD escape phenotype.Ĭritically endangered great hammerhead sharks may run on a lunar calendar They showed that the microbiome make-up of GDT escape vines differed significantly from diseased vines’ microbiota. They investigated disease escape plants, which remain healthy under high disease pressure and found that higher disease resistance is likely due to plants’ microbiome function. Writing in Frontiers in Microbiology, researchers in New Zealand found that certain grapevines are better equipped than others to stay healthy. In vines, grapevine trunk diseases (GDT) can be caused by various fungi that invade and multiply within the plants’ tissues and ultimately lead to a general deterioration of the vine’s woody structures. In the case of plants that humans harvest from, this can lead to crop reduction or failure. Just like people and animals, plants can become sick. Grapevines could owe disease resistance to microbiome structure Their method has great potential for identifying enough individuals and their sex to meaningfully contribute to questions regarding polar bear population biology, the researchers wrote. They sampled 13 polar bear trails and successfully identified sex and identity for six of the animals. Writing in Frontiers in Conservation Science, they investigated the use of environmental DNA – cells which the animals shed when walking – collected from paw-prints in the snow to identify individual polar bears and their sex. Now, a team of researchers in the US has developed a method to keep track of polar bears that might make scientist less reliant on having to capture the bears to get data. More often than not, this is a costly and difficult endeavor, in part because of the remote regions the bears inhabit. To prevent potential human-animal conflicts and to protect the species, polar bear populations must be monitored and managed. The recent loss of sea ice is forcing polar bears – one of the Arctic’s biggest predators – to spend more time on land closer to human settlements. Polar bear identity and sex can be established from paw prints Here are just five amazing papers you may have missed. But with tens of thousands of articles published each year, it’s impossible to cover all of them.
