Network of networks: Time series clustering of ameriflux sites by Reed, David E., Chu, Housen, Peter, Brad G., Chen, Jiquan, Abraha, Michael, Amiro, Brian, Anderson, Ray G., Arain, M. Altaf, Arruda, Paulo, Barron-Gafford, Greg A., Bernacchi, Carl, Beverly, Daniel P., Biraud, Sebastien C., Black, T. Andrew, Blanken, Peter D., Bohrer, Gil, Bowler, Rebecca, Bowling, David R., Forsythe, Brandon R., Posse Beaulieu, Gabriela, Zona, Donatella

“…While net radiation and temperature showed latitudinal clus­ tering as expected, flux variables revealed a more uneven clustering with many small (number of sites < 5), unique groups and a few large (> 100) to intermediate (15–70) groups, highlighting the significant ecological regulations of ecosystem fluxes. Many identified unique groups were from under-sampled ecoregions and biome types of the International Geosphere-Biosphere Programme (IGBP), with distinct flux dynamics compared to the rest of the network. …”

Staying close: short local dispersal distances on a managed forest of two Patagonian Nothofagus species by Sola, Georgina Giselle, El Mujtar, Veronica Andrea, Gallo, Leonardo Ariel, Vendramin, Giovanni Giuseppe, Marchelli, Paula

“…We aimed to determine the effect of logging on gene flow distances in two Nothofagus species from temperate Patagonian forests having high ecological relevance and wood quality. Therefore, a total of 778 individuals (mature trees and saplings) of Nothofagus alpina and N. obliqua, from a single plot managed 20 years ago (2.85 hectares), were mapped and genotyped at polymorphic nuclear microsatellite loci. …”

Plants vs. Streams: Their groundwater‐mediated competition at “El Morro”, a developing catchment in the dry plains of Argentina by Jobbagy Gampel, Esteban Gabriel, Lorenzo, Santiago, Buono, Nicolás, Páez, Ricardo, Diaz, Yésica, Marchesini, Victoria, Nosetto, Marcelo Daniel

“…Close to the deepest (20 m) and most active incisions, groundwater level and greenness declined and stream baseflow showed no seasonal fluctuations, hinting decoupling from evapotranspiration. Intense ecological and geomorphological transformations in this catchment exposed the interplay of five mechanisms governing evapotranspiration/streamflow partition including (i) unsaturated uptake and both (ii) riparian and (iii) distributed uptake from the saturated zone by plants, as well as (iv) deepening incisions and (v) sediment deposits over riparian zones by streams. …”

Evolutionary Genomics of Staphylococcus aureus Reveals Insights into the Origin and Molecular Basis of Ruminant Host Adaptation by Guinane, Caitriona M., Ben Zakour, Nouri L., Tormo-Mas, María A., Weinert, Lucy A., Lowder, Bethan V., Cartwright, Robyn A., Smyth, Cyril J., Lindsay, Jodi A., Gould, Katherine A., Witney, Adam, Hinds, Jason, Bollback, Jonathan P., Rambaut, Andrew, Penadés, José R., Fitzgerald, J. Ross

“…henotypic biotyping has traditionally been used to differentiate bacteria occupying distinct ecological niches such as host species. For example, the capacity of Staphylococcus aureus from sheep to coagulate ruminant plasma, reported over 60 years ago, led to the description of small ruminant and bovine S. aureus ecovars. …”
