The Roger Revelle Commemorative Lecture Series was created by the Ocean Studies Board of the National Academies in honor of Roger Revelle to highlight the important links between ocean sciences and public policy. Dawn J. Wright, the eighteenth annual lecturer, spoke on April 28, 2017, at the Smithsonian National Museum...
Spotted wing drosophila, Drosophila suzukii, is a devastating invasive pest of small and stone fruits in the Americas and Europe. To better understand the population dynamics of D. suzukii, we reviewed recent work on juvenile development, adult reproduction, and seasonal variation in life history parameters including the abiotic/biotic factors that...
Basaltic volcanism provides a window into the Earth’s mantle. Seeing through this window requires seeing through the processes of magma genesis and evolution that distort the view. Radiogenic isotope ratios, and to a lesser extent incompatible elements and stable isotope ratios, allow us to see through these distortions and infer...
The Asian vinegar fly Drosophila suzukii (spotted wing Drosophila [SWD]) has emerged as a major invasive insect pest of small and stone fruits in both the Americas and Europe since the late 2000s. While research efforts have rapidly progressed in Asia, North America, and Europe over the past 5 years,...
Nuclear pore complexes (NPCs) are huge assemblies formed from ~30 different nucleoporins, typically organized in subcomplexes. One module, the conserved Nup82 complex at the cytoplasmic face of NPCs, is crucial to terminate mRNA export. To gain insight into the structure, assembly, and function of the cytoplasmic pore filaments, we reconstituted...
Escape from parasites in their native range is one of many mechanisms that can contribute to the success of an invasive
species. Gnathiid isopods are blood-feeding ectoparasites that infest a wide range of fish hosts, mostly in coral reef habitats.
They are ecologically similar to terrestrial ticks, with the ability...
This article argues that the international criminal justice system fails to sufficiently address conflict-related sexual violence in two critical ways: [1] by advocating a pro-prosecution, “end impunity” approach (defined as holding perpetrators accountable through criminal, civil, administrative or disciplinary proceedings) which applies the prevailing Euro-American model of justice designed to...
Epigenetic variation is likely to contribute to the phenotypic plasticity and adaptative
capacity of plant species, and may be especially important for long-lived
organisms with complex life cycles, including forest trees. Diverse environmental
stresses and hybridization/polyploidization events can create reversible heritable
epigenetic marks that can be transmitted to subsequent generations...
