GEOMETRY, ALLOMETRY AND BIOMECHANICS OF FERN LEAF PETIOLES: THEIR SIGNIFICANCE FOR THE EVOLUTION OF FUNCTIONAL AND ECOLOGICAL DIVERSITY WITHIN THE PTERIDACEAE

Herbaceous plants rely on a combination of turgor, ground tissues and geometry for mechanical support of leaves and stems.Unlike most angiosperms however, ferns employ a sub-dermal layer of fibers, known as a hypodermal sterome, for support of their leaves.The sterome is nearly ubiquitous in ferns, but nothing is known about its role in leaf biomec

In this study, a focused investigation of the potential for the King Salmon (KS) SuperDARN HF radar to monitor high-velocity flows near the equatorial edge of the auroral oval is undertaken.Events are presented with line-of-sight velocities as high as 2km/s, observed roughly along the L-shell.Statistically, the enhanced flows are shown to be typica

IntroductionPathogen introduction and transmission at the farm, regional, or national level are associated with reduced animal welfare and negative impacts on herd economics.Ongoing infectious disease surveillance, active or passive, is therefore of high importance.For optimal resolution, each pig is sampled individually, for example by collecting

There is a worldwide need for mental health interventions to address the mental health needs of children under 12 who are returning to school in the post-COVID-19 environment.The basic characteristics of child-focused, post-crisis interventions are currently unknown, but they are essential for developing high-quality, Grill Door Hinge expedient RTC

Abstract Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the novel coronavirus disease 2019 (COVID-19), which is characterized by a diverse clinical picture.Children are often asymptomatic or experience mild symptoms and have a milder disease course compared to adults.Rectal shedding of SARS-CoV-2 has been observed in
