A dynamic species distribution model of Glossina subgenus Morsitans: The identification of tsetse reservoirs and refugia por Visser, Mark H. de, Messina, Joseph P., Moore, Nathan J., Lusch, David P., Maitima, Joseph

“…To aid control efforts we have constructed the Tsetse Ecological Distribution Model (TED Model). The TED Model is a raster based dynamic species distribution model that predicts tsetse distributions at 250 m spatial resolution, based on habitat suitability and fly movement rates, at 16‐day intervals. …”

Movement and Distribution of Ammonium-N Following Deep Placement of Urea in a Wetland Rice Soil por Savant, N.K., De Datta, S.K.

“…With time, the NH4+‐N tended to move downward more than upward from the placement sites, probably because of the mass flow of percolating water.In another experiment, the movement and spatial distribution of NH4+‐N were studied following application of 2‐g supergranules of urea (SGU) and sulfur‐coated supergranules of urea (SC‐SGU) at a depth of 10 cm in transplanted and cultivated wetland fallow plots. …”

Assessing the impact of rice price stabilization policies in Bangladesh: Results from a stochastic spatial equilibrium model por Minot, Nicholas, Hossain, Shahadat, Kabir, Razin, Dorosh, Paul A., Rashid, Shahidur

“…Although Bangladesh has largely liberalized international trade in rice, it maintains a public food distribution system to stablize prices, distributing an average of 2 million tons of rice per year at a cost of almost US$ 800 million per year. …”

Using a spatially precise approach to analyse the occurrence of Usnea longissima in relation to present and past stand structure por Josefsson, Torbjörn

“…To maintain biodiversity in managed forests, long-term trends in forest structure and ecological processes must be understood since these have a decisive influence on the distribution of many forest species, especially epiphytic lichens. …”

Spatial analysis of Fasciola hepatica prevalence in sheep flocks from Córdoba, Argentina using GWR and IDW models por Ahumada, María Del Rosario, Denegri, David, Caffe, Gabriel, Hick, Michel V.H., Paz, Juan Mariano, Aguilar, Santiago, Celis Pirard, Clara, Motta, Carlos

“…The overall prevalence was found to be 46 %, with the highest values observed in the Cruz del Eje and Pocho departments (74 %). Spatial analysis utilizing Inverse Distance Weighted (IDW) interpolation revealed a heterogeneous distribution, with a higher prevalence concentrated in the northern re gion. …”

Spatial rice yield estimation based on MODIS and Sentinel-1 SAR data and ORYZA crop growth model por Setiyono, Tri, Quicho, Emma, Gatti, Luca, Campos-Taberner, Manuel, Busetto, Lorenzo, Collivignarelli, Francesco, García-Haro, Francisco, Boschetti, Mirco, Khan, Nasreen, Holecz, Francesco

“…Results from this study indicate that the approach of assimilating MODIS and SAR data into a crop growth model can generate well-adjusted yield estimates that adequately describe spatial yield distribution in the study area while reliably replicating official yield data with root mean square error, RMSE, of 0.30 and 0.46 t ha−1 (normalized root mean square error, NRMSE of 5% and 8%) for the 2016 spring and summer seasons, respectively, in the Red River Delta of Vietnam, as evaluated at district level aggregation. …”
