Metazoans of redoxcline sediments in Mediterranean deep-sea hypersaline anoxic basins
(2015)The deep-sea hypersaline anoxic basins (DHABs) of the Mediterranean (water depth similar to 3500 m) are some of the most extreme oceanic habitats known. Brines of DHABs are nearly saturated with salt, leading many to suspect ... -

MicroRNAs control mRNA fate by compartmentalization based on 3 ' UTR length in male germ cells
(2017)Post-transcriptional regulation of gene expression can be achieved through the control of mRNA stability, cytoplasmic compartmentalization, 3' UTR length and translational efficacy. Spermiogenesis, a process through which ... -

miR-124 Regulates the Phase of Drosophila Circadian Locomotor Behavior
(2016)Animals use circadian rhythms to anticipate daily environmental changes. Circadian clocks have a profound effect on behavior. In Drosophila, for example, brain pacemaker neurons dictate that flies are mostly active at dawn ... -

Mitochondrial O-GlcNAc Transferase (mOGT) Regulates Mitochondrial Structure, Function, and Survival in HeLa Cells
(2017)O-Linked N-acetylglucosamine transferase (OGT) catalyzes O-GlcNAcylation of target proteins and regulates numerous biological processes. OGT is encoded by a single gene that yields nucleocytosolic and mitochondrial isoforms. ... -

Molecular evolution of DNMT1 in vertebrates: Duplications in marsupials followed by positive selection
(2018)DNA methylation is mediated by a conserved family of DNA methyltransferases (Dnmts). The human genome encodes three active Dnmts (Dnmt1, Dnmt3a and Dnmt3b), the tRNA methyltransferase Dnmt2, and the regulatory protein ... -

Mollusc fisheries and length-weight relationship in Tonle Sap flood pulse system, Cambodia
(2018)Molluscs are important for ecological function, livelihoods and fisheries, but are often forgotten in research and management. Here, we investigated intra-annual variation in the landing and growth patterns of three mollusc ... -

Netrin1-DCC-Mediated Attraction Guides Post-Crossing Commissural Axons in the Hindbrain
(2015)Commissural axons grow along precise trajectories that are guided by several cues secreted from the ventral midline. After initial attraction to the floor plate using Netrin1 activation of its main attractive receptor, DCC ... -

Nitrogen and Phosphorus Uptake Dynamics in Tropical Cerrado Woodland Streams
(2018)Pollution abatement through phosphorus and nitrogen retention is a key ecosystem service provided by streams. Human activities have been changing in-stream nutrient concentrations, thereby altering lotic ecosystem functioning, ... -

Opening the file drawer: Unexpected insights from a chytrid infection experiment
(2018)Infection experiments are critical for understanding wildlife disease dynamics. Although infection experiments are typically designed to reduce complexity, disease outcomes still result from complex interactions between ... -

Orienting the Interaction Compass: Resource Availability as a Major Driver of Context Dependence
(2016)Life on earth is enormously diverse, in part because each individual engages in countless interactions with its biotic and abiotic environment during its lifetime. Not only are there many such interactions, but any given ... -

Overstory-derived surface fuels mediate plant species diversity in frequently burned longleaf pine forests
(2017)Frequently burned low-latitude coniferous forests maintain a high-diversity understory. Longleaf pine (Pinus palustris Mill.) forests and woodlands have exceptionally high diversity at fine scales and very frequent fire ... -

Patterns of Spatial Distribution of Golden Eagles Across North America: How Do They Fit into Existing Landscape-Scale Mapping Systems?
(2017)Conserving wide-ranging animals requires knowledge about their year-round movements and resource use. Golden Eagles (Aquila chrysaetos) exhibit a wide range of movement patterns across North America. We combined tracking ... -

Phylogenetic Distribution of CMP-Neu5Ac Hydroxylase (CMAH), the Enzyme Synthetizing the Proinflammatory Human Xenoantigen Neu5Gc
(2018)The enzyme CMP-N-acetylneuraminic acid hydroxylase (CMAH) is responsible for the synthesis of N-glycolylneuraminic acid ( Neu5Gc), a sialic acid present on the cell surface proteins of most deuterostomes. The CMAH gene is ... -

Phytochemical diversity drives plant-insect community diversity
(2015)What are the ecological causes and consequences of variation in phytochemical diversity within and between plant taxa? Despite decades of natural products discovery by organic chemists and research by chemical ecologists, ... -

Position Matters: Network Centrality Considerably Impacts Rates of Protein Evolution in the Human Protein-Protein Interaction Network
(2017)The proteins of any organism evolve at disparate rates. A long list of factors affecting rates of protein evolution have been identified. However, the relative importance of each factor in determining rates of protein ... -

Positive Selection and Centrality in the Yeast and Fly Protein-Protein Interaction Networks
(3/28/2016)Proteins within a molecular network are expected to be subject to different selective pressures depending on their relative hierarchical positions. However, it is not obvious what genes within a network should be more ... -

Protein structural disorder of the envelope V3 loop contributes to the switch in human immunodeficiency virus type 1 cell tropism
(2017)Human immunodeficiency virus type 1 (HIV-1) envelope gp120 is partly an intrinsically disordered (unstructured/disordered) protein as it contains regions that do not fold into well-defined protein structures. These disordered ... -

Quantification of mesocosm fish and amphibian species diversity via environmental DNA metabarcoding
(2016)Freshwater fauna are particularly sensitive to environmental change and disturbance. Management agencies frequently use fish and amphibian biodiversity as indicators of ecosystem health and a way to prioritize and assess ... -

Rates of niche and phenotype evolution lag behind diversification in a temperate radiation
(2019)Environmental change can create opportunities for increased rates of lineage diversification, but continued species accumulation has been hypothesized to lead to slowdowns via competitive exclusion and niche partitioning. ... -

Resurrection and re-description of Plethodontohyla laevis (Boettger, 1913) and transfer of Rhombophryne alluaudi (Mocquard, 1901) to the genus Plethodontohyla (Amphibia, Microhylidae, Cophylinae)
(2018)The systematics of the cophyline microhylid frog genera Plethodontohyla and Rhombophryne have long been intertwined, and their relationships have only recently started to become clear. While Rhombophryne has received a lot ...
