Extensive Admixture Among Karst-Obligate Salamanders Reveals Evidence of Recent Divergence and Gene Exchange Through Aquifers.

Karst ecosystems often contain extraordinary biodiversity, but the complex underground aquifers of karst regions present challenges for assessing and conserving stygobiont diversity and investigating their evolutionary history. We examined the karst-obligate salamanders of the species complex in the Edwards Plateau region of central Texas using population genomics data to address questions about population connectivity and the potential for gene exchange within the underlying aquifer system. The species complex has historically been divided into three nominal species, but their status, and spatial extent of species ranges, have remained uncertain.

Clinical helpline: communicating and improving inpatient experience and safety using digital health records.

The clinical telephone helpline discussed here is a communication channel for family members and caregivers whose loved ones are in hospital. It makes full use of the effect families can have on the care experience and complements standard visiting as well as when hospital visits are restricted. The helpline helps to meet family members' health information and emotional wellbeing needs and is a reciprocal patient safety communication channel.
