Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

Wildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

An Extended Kriging Method to Interpolate Near-Surface Soil Moisture Data Measured by Wireless Sensor Networks

Sensors, 2017
In the practice of interpolating near-surface soil moisture measured by a wireless sensor network (WSN) grid, traditional Kriging methods with auxiliary variables, such as Co-kriging and Kriging with external drift (KED), cannot achieve satisfactory ...

Regional Prediction of Soil Nutrient Availability and Management Using Portable X‐Ray Fluorescence Spectrometry

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable x‐ray fluorescence (pXRF) spectroscopy has emerged as a rapid and cost‐effective technique for soil elemental analysis; however, its application for predicting available nutrients and supporting agronomic decision making remains insufficiently evaluated under field conditions.

Kriging for Interpolation in Random Simulation [PDF]

Whenever simulation requires much computer time, interpolation is needed. There are several interpolation techniques in use (for example, linear regression), but this paper focuses on Kriging.This technique was originally developed in geostatistics by D ...

Environmental drivers influencing the ambrosia beetle community: The primary role of geographic and climatic drivers in chestnut‐growing areas

Agricultural and Forest Entomology, EarlyView.
Ethanol‐baited traps were placed in cultivated chestnut orchards (a) and mixed environments with assorted tree composition (b), over a 2‐year monitoring period in two valleys (NW Italy). A total of 118,286 ambrosia beetles was collected, representing six species.

A New Approach to Transforming Airborne Electromagnetic Data into Models of Sediment Type

Groundwater, EarlyView.
A new methodology provides the relationship needed to transform electrical resistivity measurements from airborne electromagnetic surveys to sediment type. By accounting for the physics of the measurement and the quality of the driller's logs used in developing the transform, the method improves the accuracy of derived sediment type models.
