Mixed network former effects in oxide glasses: spectroscopic studies in the system (M2O)1/3[(Ge2O4)x(P2O5)1-x]2/3
(American Chemical Society - ACSWashington, DC, 2014-05)
The structure of mixed-network former glasses in the system (M2O)0.33[(Ge2O4)x(P2O5)1-x]0.67.(M = Na, K) has been studied by 31P and 23Na high-resolution and dipolar solid state nuclear magnetic resonance (NMR) techniques, ...
An inverse latitudinal gradient in infection probability and phylogenetic diversity for Leucocytozoon blood parasites in New World birds
(Wiley Blackwell Publishing, Inc, 2020-02)
Geographic variation in environmental conditions as well as host traits that promote parasite transmission may impact infection rates and community assembly of vector-transmitted parasites. Identifying the ecological, ...
Connection, isolation and reconnection: Quaternary climatic oscillations and the Andes shaped the phylogeographical patterns of the Patagonian bee Centris cineraria (Apidae)
(Wiley Blackwell Publishing, Inc, 2020-08)
The joint effect of the Andes as a geographical barrier and the Quaternary glaciations as promoters of genetic divergence remains virtually unexplored in southern South America. To help fill this knowledge gap, in this ...
Nested association mapping of stem rust resistance in wheat using genotyping by sequencing
(Public Library of Science, 2017)
A multivariate geostatistical framework for combining multiple indices of abundance for disease vectors and reservoirs: A case study of rattiness in a low-income urban Brazilian community
(The Royal Society, 2020-09)
A key requirement in studies of endemic vector-borne or zoonotic disease is an estimate of the spatial variation in vector or reservoir host abundance. For many vector species, multiple indices of abundance are available, ...
Biodiversity simultaneously enhances the production and stability of community biomass, but the effects are independent
(Ecological Society of America, 2013-02)
Human domination of the planet is dismantling Earth´s ecosystems one gene, species, and biological trait at a time. To predict the ecological consequences of biodiversity loss, researchers have spent much of the past two ...
On the complementary information provided by satellite images, Lagrangian drifters and a regional numerical model: a case study in the San Matias Gulf, Argentina
(Springer, 2020-06)
Satellite images are of great help to understand the ocean circulation. In coastal regions, high-resolution images of chlorophyll-a (chl-a) concentration deliver a very accurate picture of the coastal currents and jets ...
Integrated ecological modelling for decision support and risk assessment in river water quality management
(2016)
Modelling is an effective tool to investigate or to predict the ecological state of water
resources and the response to natural driving variables or anthropogenic pressures.
Model integration is required to perform ...
