Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations. This is interpreted as indicating a greater proportion of Upper North Atlantic Deep Water (UNADW)...
How do you test a program when only a single user, with no expertise in software testing, is able to determine if the
program is performing correctly? Such programs are common today in the form of machine-learned classifiers. We consider the
problem of testing this common kind of machine-generated program...
A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive
film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating
magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing
acoustic waves, respectively. The magnetization pattern is size-tunable,...
The sustainability of the food system is at the forefront of academic and policy discussions as we face the challenge of providing food security to a growing population amidst environmental uncertainty and depletion, social disruptions, and structural economic shocks and stresses. Crafting a sustainable and resilient food system requires us...
We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic
cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the
opportunity to examine the cascading effects of carnivore–herbivore interactions...
Using spatial autocorrelation analysis, we
examined the within-population genetic structure of
Rhizopogon vinicolor and R. vesiculosus, two hypogeous
ectomycorrhizal (EM) species that are sympatric
sister taxa known to differ in their clonal structure.
We collected 121 sporocarps and 482 tuberculate EM
of both species from a 20 ha forest stand...
Body size is known to correlate with many aspects of life history in birds, and this knowledge can be used to manage and conserve bird species. However, few studies have compared the wintering ecology of sympatric subspecies that vary significantly in body size. We used radiotelemetry to examine the relationship...
The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before
Euro-American settlement.We used the journal entries to assess the influence of humans on wildlife distribution and abundance. Areas with
denser human population, such as the Columbia...
There has been much discussion in the conservation and policy realms of COVID-19 as a zoonotic disease, or a disease transmitted from wildlife to humans. However, wildlife consumption in China is not only a potential source of disease but also a practice embedded in complex beliefs about health. This paper...
Background: Next-generation sequencing and 'omics' platforms are used extensively in plant biology research to unravel new genomes and study their interactions with abiotic and biotic agents in the growth environment. Despite the availability of a large and growing number of genomic data sets, there are only limited resources providing highly-curated...
