Control of mobile pests frequently requires area-wide management (AWM) that spans commercial and non-commercial habitats. Spatial modelling of habitat suitability can guide investment and implementation of AWM, but current approaches rarely capture population drivers, including local foraging, at an appropriate spatial resolution. To support the de...
BACKGROUND: This study investigated how infestation rates of an important oilseed rape pest, the cabbage seed weevil (Ceutorhynchus obstrictus) and rates of parasitization by its parasitoids are affected by land use, up to 1000 m from 18 focal fields. RESULTS: The mean proportion of C. obstrictus-infested pods per plant was 8% (2–19.5%). Infestatio...
The objective of the study was to classify 80,246 hectares on the right bank of the Paraguay river belonging to the Chaco Humid region. On two occasions, in 2000 and 2016, was interpreted the vegetal cover and the land use of this area. In the year 2000, through the analysis of the satellite image interpretation on a scale of 1:50,000 were delimite...
The need to understand patterns and processes in the marine environment has never been so profound as today, particularly as anthropogenic pressures upon coastal regions are drastically affecting habitats and species across a vast range. One approach to further understand these patterns and processes is through the use of seascape ecology methods. ...
This paper combines remote sensing, environmental modeling, and landscape ecology to investigate the impacts of the expansion of eucalyptus reforestation. Using these techniques, a methodology was developed to analyze and predict future land cover and landscape structure trends. The study area was comprised of the river basin municipalities in Rio ...
The Brazilian Atlantic Forest and Brazilian Savanna (i.e., Cerrado) are classified as World Biodiversity Hotspots. Our goal was to analyze the spatial distribution of endangered species in both habitats within the Mourao River basin, southern Brazil. Forest remnants were mapped using Landsat 8 satellite images applying NDVI medium and landscape met...
Estudos de fragmentos florestais devem incluir a paisagem. Portanto, o objetivo do estudo foi analisar métricas de paisagem de dois fragmentos florestais e a influência dos usos do solo e cobertura vegetal em seu entorno, inseridos na bacia hidrográfica do rio Murundú-Paiol. Foi realizado o mapeamento do uso do solo e cobertura vegetal, para 2018, ...
The southeastern United States is home to the highest amphibian species richness in North America. An often overlooked component of research on factors that drive amphibian geographic distributions is description of species range shape. Broad-scale range disjunction has implications for phylogeography, ecology, and conservation, but descriptions of...

In scenarios of future climate change, there is a projectedincrease in the occurrence and severity of natural disturbances inboreal forests. Spruce budworm (Choristoneura fumiferana)(SBW) is the main defoliator of conifer trees in the North American boreal forests affecting large areas and causing marked losses of timber supplies. However, the impa...

Species distribution models can be made more accurate by use of new "Spatiotemporal Exploratory Models" (STEMs), a type of spatially explicit ensemble model (SEEM) developed at the continental scale that averages regional models pixel by pixel. Although SEEMs can generate more accurate predictions of species distributions, they are computationally ...
