Endometrial luminal epithelial cells sense embryo elongation in the roe deer independent of interferon-tau†
(2019)Biology of ReproductionNumerous intrauterine changes take place across species during embryo development. Following fertilization in July/August, the European roe deer (Capreolus capreolus) embryo undergoes diapause until embryonic elongation in December/January. Embryonic elongation prior to implantation is a common feature among ungulates. Unlike many other ruminants, the roe deer embryo does not secrete interferon-tau (IFNτ). This provides the unique opportunity ...Journal Article -
Dynamic changes in cerebral and peripheral markers of glutamatergic signaling across the human sleep–wake cycle
(2019)SleepSleep and brain glutamatergic signaling are homeostatically regulated. Recovery sleep following prolonged wakefulness restores efficient functioning of the brain, possibly by keeping glutamatergic signaling in a homeostatic range. Evidence in humans and mice suggested that metabotropic glutamate receptors of subtype-5 (mGluR5) contribute to the brain’s coping mechanisms with sleep deprivation. Here, proton magnetic resonance spectroscopy ...Journal Article -
A Minimal Model for the Latitudinal Diversity Gradient Suggests a Dominant Role for Ecological Limits
(2019)The American NaturalistThe latitudinal diversity gradient (LDG) is one of Earth’s most iconic biodiversity patterns and still one of the most debated. Explanations for the LDG are often categorized into three broad pathways in which the diversity gradient is created by (1) differential diversification rates, (2) differential carrying capacities (ecological limits), or (3) differential time to accumulate species across latitude. Support for these pathways has, ...Journal Article -
Carbon neutral expansion of oil palm plantations in the Neotropics
(2019)Science AdvancesAlternatives to ecologically devastating deforestation land use change trajectories are needed to reduce the carbon footprint of oil palm (OP) plantations in the tropics. Although various land use change options have been proposed, so far, there are no empirical data on their long-term ecosystem carbon pools effects. Our results demonstrate that pasture-to-OP conversion in savanna regions does not change ecosystem carbon storage, after ...Journal Article -
Mechanistic reconstruction of glycoprotein secretion through monitoring of intracellular N-glycan processing
(2019)Science AdvancesN-linked glycosylation plays a fundamental role in determining the thermodynamic stability of proteins and is involved in multiple key biological processes. The mechanistic understanding of the intracellular machinery responsible for the stepwise biosynthesis of N-glycans is still incomplete due to limited understanding of in vivo kinetics of N-glycan processing along the secretory pathway. We present a glycoproteomics approach to monitor ...Journal Article -
What the Proportional Recovery Rule Is (and Is Not): Methodological and Statistical Considerations
(2019)Neurorehabilitation and Neural RepairIn 2008, it was proposed that the magnitude of recovery from nonsevere upper limb motor impairment over the first 3 to 6 months after stroke, measured with the Fugl-Meyer Assessment (FMA), is approximately 0.7 times the initial impairment (“proportional recovery”). In contrast to patients with nonsevere hemiparesis, about 30% of patients with an initial severe paresis do not show such recovery (“nonrecoverers”). Hence it was suggested ...Journal Article -
Symplasmic phloem unloading and radial post-phloem transport via vascular rays in tuberous roots of Manihot esculenta
(2019)Journal of Experimental BotanyCassava (Manihot esculenta) is one of the most important staple food crops worldwide. Its starchy tuberous roots supply over 800 million people with carbohydrates. Yet, surprisingly little is known about the processes involved in filling of those vital storage organs. A better understanding of cassava carbohydrate allocation and starch storage is key to improving storage root yield. Here, we studied cassava morphology and phloem sap flow ...Journal Article -

Novel excitations near quantum criticality in geometrically frustrated antiferromagnet CsFeCl3
(2019)Science AdvancesThe investigation of materials that exhibit quantum phase transition provides valuable insights into fundamental problems in physics. We present neutron scattering under pressure in a triangular-lattice antiferromagnet that has a quantum disorder in the low-pressure phase and a noncollinear structure in the high-pressure phase. The neutron spectrum continuously evolves through critical pressure; a single mode in the disordered state becomes ...Journal Article -
A global synthesis reveals biodiversity-mediated benefits for crop production
(2019)Science AdvancesHuman land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield–related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for pollination; biological pest control; and ...Journal Article
