Roadside collection of training data for cropland mapping is viable when environmental and management gradients are surveyed
(Elsevier, 2019-08)
Cropland maps derived from satellite imagery have become a common source of information to estimate food production, support land use policies, and measure the environmental impacts of agriculture. Cropland classification ...

Evaluation of species richness estimators in studies of diversity involving two larval digenean communities parasitizing snail hosts
(Springer, 2010-07)
The nonparametric estimators of species richness are some of the most widely used extrapolation methods in studies of biodiversity. These studies need relative large samples to achieve total diversity (including rare ...
Influence of particle size on the conductance of SnO2 thick films
(Elsevier, 2003-03-06)
The electrical response of SnO2 thick films was found to be highly dependent on the grain size. This result can be explained as the consequence of the type of intergranular potential barriers developed at intergrains. ...
Considerations for monitoring population trends of colonial waterbirds using the effective number of breeders and census estimates
(Wiley, 2018-06)
Detecting trends in population size fluctuations is a major focus in ecology, evolution,and conservation biology. Populations of colonial waterbirds have been monitoredusing demographic approaches to determine annual census ...
Osmotic dehydration of Pumpkin (Cucurbita moschata) in sucrose and sucrose-salt solutions. Effect of solution composition and sample size
(Planta Piloto de Ingeniería Química, 2020-06)
Mass transfer during osmotic dehydration (OD) of Anco pumpkin cubes was studied as a function of sample size and composition and concentration of sucrose dehydrating solution. Models of Azuara and Hawkes & Flink were ...
