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

The Effects of Crop Insurance Subsidies and Sodsaver on Land-Use Change

Journal of Agricultural and Resource Economics, 2016
It is well known that insurance market information asymmetry can cause socially excessive cropping of yield-risky land. We show that crop insurance subsidies can cause the same problem absent information failures. Using field-level yield data, we find an

Assessing prioritization measures for a private land conservation program in the U.S. Prairie Pothole Region

Conservation Science and Practice, 2023
Private land conservation has become an important tool for protecting biodiversity and habitat, but methods for prioritizing and scheduling conservation on private land are still being developed.

Agricultural activities lead to sediment infilling of wetlandscapes in the Canadian Prairies: Assessment of contributions by tillage, water and wind erosion

Geoderma, 2023
Soil erosion and sediment delivery models have been increasingly employed in studies of catchment sediment dynamics in current years. These models are also used to represent the spatial interaction of soil erosion and sediment transport processes ...

Soil carbon dynamics in drained prairie pothole wetlands

Frontiers in Environmental Science
Drainage leads to trade-offs between crop production efficiency and wetland conservation, with complex impacts on ecosystem services. In North America’s Prairie Pothole Region, wetland drainage is widespread, often to increase the available land for ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Cognitive and institutional barriers to effective natural resource management under global change

Conservation Biology, EarlyView.
Abstract Many of the most challenging decisions facing natural resource managers today can be understood as time dependent. The concept of time‐dependent decisions is useful when considering natural resource management decisions that are characterized by nonstationarity in the underlying ecological system, uncertainty surrounding key ecological ...

A predictive model for seasonal pond counts in the United States Prairie Pothole Region using large-scale climate connections

Environmental Research Letters, 2020
The Prairie Pothole Region (PPR), located in central North America, is an important region hydrologically and ecologically. Millions of wetlands, many containing ponds, are located here, and they serve as habitats for various biota and breeding grounds ...

Functional dispersion of wetland birds, invertebrates, and plants more strongly influenced by hydroperiod than each other

Ecosphere, 2022
The relative role of biological and abiotic filters in the assembly of co‐occurring taxa is of broad interest to ecologists. While some authors point to biological interactions (e.g., competition) as the stronger driver of ecological selection, others ...
