Baleen Whale Occurrence in the Waters Off Virginia and North Carolina, U.S.A. From 2001 to 2019NARA Subscribed
Eighteen years of visual survey and strandings data were used to describe baleen whale occurrence along the continental shelf of Virginia and North Carolina, U.S.A. This region experiences heavy anthropogenic use, which poses risks for mortality and injury to baleen whales. Between 2001 and 2019, six species of baleen whales were recorded, and whales occurred year‐round. The total number of (on‐ and off‐effort) sightings and s...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Phylogeography and bindin evolution in Arbacia , a sea urchin genus with an unusual distributionNARA Subscribed
Among shallow water sea urchin genera, Arbacia is the only genus that contains species found in both high and low latitudes. In order to determine the geographical origin of the genus and its history of speciation events, we constructed phylogenies based on cytochrome oxidase I and sperm bindin from all its species. Both the mitochondrial and the nuclear gene genealogies show that Arbacia originated in the temperate zone of th...
Transcriptional and biochemical signatures of divergence in natural populations of two species of New Zealand alpine PachycladonNARA Subscribed
New Zealand is diverse in alpine and subalpine environments, a consequence of Late Tertiary tectonic and climatic change. However, few studies have sought to evaluate the importance of these environments as abiotic drivers in the diversification of plant species. Of particular interest is the Late Tertiary radiation of Pachycladon , an endemic New Zealand genus of alpine cress. Here we report observations on genome‐wide levels...
The South Island, New Zealand, endemics Lepidium sisymbrioides and L. solandri are accepted at species rank. L. solandri Kirk is reinstated and includes L. matau Petrie in synonymy, and L. kawarau is reduced to synonymy of L. sisymbrioides . Twenty‐nine floral and vegetative morphological characters were measured and used for analyses of character variation and principal components analysis. Leaf characters proved to be the mo...
Growth habit, vegetative, floral characters, and molecular data support the recognition of Ranunculus haastii and R. piliferus at species rank, rather than as intraspecific taxa at the rank of subspecies. Therefore, R. piliferus is a new combination at species rank for plants previously known as R. haastii subsp. piliferus. R. acraeus is a new species distinguished from R. piliferus by its finely crenate leaf and bract margins...
Markers derived from amplified fragment length polymorphism gels for plant ecology and evolution studiesNARA Subscribed
We describe the types of polymerase chain reaction (PCR) markers that we have isolated using amplified fragment length polymorphisms (AFLP) in closely related taxa from diverse plant genera. With these markers, both inter‐ and intraspecific differences have been identified. The characterization of the nucleotide sequences and fragment length polymorphisms of such AFLP‐derived PCR markers is promising for investigating the ecol...
