The Snell’s waltzer mouse ( Myo6 sv/sv ) serves as a model for human deafness and vestibular behavioral impairment, caused by a spontaneous 130 bp recessive deletion in the Myo6 gene. In this study, we characterized the auditory and vestibular phenotypes of Myo6 sv/sv mice. These mice exhibit profound hearing loss, with cochlear hair cell stereocilia beginning to fuse soon after birth, ultimately leading to disorganization of...
Keystone species and ecosystem engineers play critical roles in maintaining and enhancing biodiversity by modifying their environment and creating ecological niches that support a wide range of organisms. The gopher tortoise ( Gopherus polyphemus ) is a prime example in the longleaf pine sandhill ecosystems of southeastern United States. Although the gopher tortoise’s positive influence on aboveground biodiversity (especially...
Local Adaptation and Osmoregulatory Mechanisms of the Copepod Acartia tonsa Under Low Salinity StressNARA Subscribed
Salinity—an essential factor shaping marine species distributions—is rapidly shifting due to global change, yet the mechanisms of salinity tolerance and adaptation remain poorly understood. We investigated local adaptation in the calanoid copepod Acartia tonsa , a broadly distributed marine species that thrives in the brackish Baltic Sea. Using a common‐garden design, we compared physiological and transcriptomic responses to l...
Introgression, Phylogeography, and Genomic Species Cohesion in the Eastern North American White Oak SyngameonNARA Subscribed
Hybridization and interspecific gene flow play a substantial role in the evolution of plant taxa. The eastern North American white oak syngameon, a group of approximately 15 ecologically, morphologically and genomically distinguishable species, has long been recognised as a model system for studying introgressive hybridization in temperate trees. However, the prevalence, genomic context and environmental correlates of introgre...
Omega-3 world map: 2024 updateNARA Subscribed
Numerous seabird species are experiencing population declines, and this trend is expected to continue or even accelerate in the future. To understand the effects of environmental change on seabird populations, long-term studies are vital, but rare. Here, we present over four decades (1978–2020) of population dynamic and reproductive performance data of Wilson’s Storm Petrels ( Oceanites oceanicus ) from King George Island (Isl...
Populations on the edge of a species' distribution may represent an important source of adaptive diversity, yet these populations tend to be more fragmented and are more likely to be geographically isolated. Lack of genetic exchanges between such populations, due to barriers to animal movement, can not only compromise adaptive potential but also lead to the fixation of deleterious alleles. The south‐eastern edge of chimpanzee...
Global phylogeography of ridley sea turtles (Lepidochelys spp.): evolution, demography, connectivity, and conservationNARA Subscribed
Globally distributed marine taxa are well suited for investigations of biogeographic impacts on genetic diversity, connectivity, and population demography. The sea turtle genus Lepidochelys includes the wide-ranging and abundant olive ridley ( L. olivacea ), and the geographically restricted and ‘Critically Endangered’ Kemp’s ridley ( L. kempii ). To investigate their historical biogeography, we analyzed a large dataset of mit...

Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals and the mobilisation of substantial resources. While the reasons are varied, investments in both research and conservation of freshwater biodiversity lag far behind those in the terrestrial and marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five research...
