Honey bee colony losses are a major concern in the USA and across the globe. Long-term data on losses
are critical for putting yearly losses in context. US colony loss surveys have been conducted yearly since the winter
of 2006–2007. Here, we report the results from the eighth annual survey...

Research in warm-climate biomes has shown
that invasion by symbiotic dinitrogen (N₂)-fixing plants can
transform ecosystems in ways analogous to the transformations
observed as a consequence of anthropogenic, atmospheric
nitrogen (N) deposition: declines in biodiversity, soil
acidification, and alterations to carbon and nutrient cycling,
including increased N losses through nitrate...

Polycomb Repressive Complex 2 (PRC2) function and DNA methylation (DNAme) are typically correlated with gene repression. Here, we show that PRC2 is required to maintain expression of maternal microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) from the Gtl2-Rian-Mirg locus, which is essential for full pluripotency of iPSCs. In the absence...

To determine how well DNA barcodes from the chloroplast region perform in forest dynamics plots
(FDPs) from global CTFS-ForestGEO network, we analyzed DNA barcoding sequences of 1277 plant
species from a wide phylogenetic range (3 FDPs in tropics, 5 in subtropics and 5 in temperate zone)
and compared the rates...

The Leguminosae has emerged as a model for studying angiosperm plastome evolution because of its striking diversity of structural rearrangements and sequence variation. However, most of what is known about legume plastomes comes from few genera representing a subset of lineages in subfamily Papilionoideae. We investigate plastome evolution in subfamily...

Eukaryotic ribosome biogenesis involves ~200 assembly
factors, but how these contribute to ribosome
maturation is poorly understood. Here, we
identify a network of factors on the nascent 60S subunit
that actively remodels preribosome structure. At its hub is
Rsa4, a direct substrate of the force-generating ATPase
Rea1. We show that...

Drosophila suzukii (Spotted Wing Drosophila) has recently become a serious invasive pest of fruit crops in the USA, Canada, and Europe, leading to substantial economic losses. D. suzukii is a direct pest, ovipositing directly into ripe or ripening fruits; in contrast, other Drosophilids utilize decaying or blemished fruits and are...

Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013,...

Sodium-ion batteries are emerging as a highly promising technology for large-scale energy
storage applications. However, it remains a significant challenge to develop an anode with
superior long-term cycling stability and high-rate capability. Here we demonstrate that the
Na⁺ intercalation pseudocapacitance in TiO₂/graphene nanocomposites enables high-rate
capability and long cycle life...

Large-scale poisoning events are common to scavenging bird species that forage communally,
many of which are in decline. To reduce the threat of poisoning and compensate for other persistent threats,
management, including supplemental feeding, is ongoing for many reintroduced and endangered vulture
populations. Through a longitudinal study of lead exposure...

invaders, but less is known about which processes
determine the differential success of invasions. In this
