Bootstrap estimation of resource selection probability functions [PDF]

, 2013
Resource selection functions (RSFs) are used for quantify how animals are selective in the use of the habitat period or food. A Resource Selection Probability Function (RSPF) can be estimated if N, the total number of units in the population, and n1 the ...

The influence of a conservation‐based grazing program on greater sage‐grouse habitat selection

Conservation Science and Practice
Understanding how vegetation management affects animals' habitat selection patterns is critical for comprehensive conservation planning. As part of a decade‐long study (2011–2019) of 486 adult female sage‐grouse in central Montana, we investigated how a ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
