Recurrent hybridization and recent origin obscure phylogenetic relationships within the ‘white-headed’ gull (Larus sp.) complex
Sarah A. Sonsthagen, Robert E. Wilson, Terry Chesser, Jean-Marc Pons, Pierre-Andre Crochet, Amy Driscoll, Carla Dove
2016, Molecular Phylogenetics and Evolution (103) 41-54
Species complexes that have undergone recent radiations are often characterized by extensive allele sharing due to recent ancestry and (or) introgressive hybridization. This can result in discordant evolutionary histories of genes and heterogeneous genomes, making delineating species limits difficult. Here we examine the phylogenetic relationships among a complex group of...
Differential heating in the Indian Ocean differentially modulates precipitation in the Ganges and Brahmaputra basins
Md Shahriar Pervez, Geoffrey M. Henebry
2016, Remote Sensing (8) 1-16
Indo-Pacific sea surface temperature dynamics play a prominent role in Asian summer monsoon variability. Two interactive climate modes of the Indo-Pacific—the El Niño/Southern Oscillation (ENSO) and the Indian Ocean dipole mode—modulate the amount of precipitation over India, in addition to precipitation over Africa, Indonesia, and Australia. However, this modulation is...
Large along-strike variations in the onset of Subandean exhumation: Implications for Central Andean orogenic growth
Richard O. Lease, T.A. Ehlers, E. Enkelmann
2016, Earth and Planetary Science Letters (451) 62-76
Plate tectonics drives mountain building in general, but the space-time pattern and style of deformation is influenced by how climate, geodynamics, and basement structure modify the orogenic wedge. Growth of the Subandean thrust belt, which lies at the boundary between the arid, high-elevation Central Andean Plateau and its humid, low-elevation...
Loads of nitrate, phosphorus, and total suspended solids from Indiana watersheds
Aubrey R. Bunch
2016, Proceedings of the Indiana Academy of Science (125) 137-150
Transport of excess nutrients and total suspended solids (TSS) such as sediment by freshwater systems has led to degradation of aquatic ecosystems around the world. Nutrient and TSS loads from Midwestern states to the Mississippi River are a major contributor to the Gulf of Mexico Hypoxic Zone, an area of...
