Spatial variability of short-term effect of tillage on soil penetration resistance
(Taylor & Francis, 2019-04)
The effect of tillage on soil properties varies within field due to spatial variability of soils. Mapping changes of soil penetration resistance (PR) would be useful to understand and assess tillage practices to alleviate ...
The scale dependency of spatial crop species diversity and its relation to temporal diversity
(National Academy of Sciences, 2020-10-20)
Increasing crop species diversity can enhance agricultural sustainability, but the scale dependency of the processes that shape diversity and of the effects of diversity on agroecosystems is insufficiently understood. We ...
Spatially explicit inference for open populations: Estimating demographic parameters from camera-trap studies
(Ecological Society of America, 2010-11-01)
We develop a hierarchical capture-recapture model for demographically open populations when auxiliary spatial information about location of capture is obtained. Such spatial capture-recapture data arise from studies based ...
Assessing spatial genetic structure from molecular marker data via principal component analyses: a case study in a Prosopis sp. fores
(Scientific Research Publishing, 2014-01)
Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, ...
Spatial analysis of vicariance: A method for using direct geographical information in historical biogeography
(Wiley Blackwell Publishing, Inc, 2011-12)
Based on Hovenkamp's ideas on historical biogeography, we present a method for analysis of taxon history, spatial analysis of vicariance, which uses observed distributions as data, thus requiring neither predefined areas ...
Morphometric classification and spatial distribution of Philippine volcanoes
(Elsevier Science, 2021-10)
The Philippine Island Arc has a large number of volcanoes with diverse morphologies, making it an ideal location to study the factors controlling the morphology and spatial distribution of island arc volcanoes. We have ...
Occurrence and spatial distribution of organochlorine pesticides in the southwest Buenos Aires using the freshwater snail Chilina parchappii as environmental biomonitor
(Elsevier, 2020-01)
Organochlorine pesticides are highly toxic compounds for biota and humans that have been used for sanitary and phytosanitary purposes for many years in Argentina and the world due to their low cost and versatility. Despite ...
Suspension feeders as natural sentinels of the spatial variability in food sources in an Antarctic fjord: A stable isotope approach
(Elsevier Science, 2020-08)
We examined the effect of glacial melt-related retreat environmental conditions on the spatial heterogeneity of food sources for Antarctic nearshore marine benthic communities of Potter Cove, a representative fjord on King ...
Phylogeographical spatial diffusion analysis reveals the journey of Geoffroy's cat through the Quaternary glaciations of South America
(Wiley Blackwell Publishing, Inc, 2020-02)
Leopardus geoffroyi is a small feline with a widespread distribution in a broad array of habitats. Here we investigate its evolutionary history to characterize the phylogeographical patterns that led to its present ...
