Abstract Land‐use and land‐cover change associated with agriculture is one of the main drivers biodiversity loss. In heavily modified agricultural landscapes, grazing lands may be only areas that can provide essential resources for native grassland species. Management decisions, such as choice livestock species, affect extent to which suitable habitat species pollinators. Our study compared how sheep versus cattle herbivory affected floral butterfly abundance across low‐diversity, former...
Abstract Background There is considerable interest in the suitability of farm-flock Katahdin hair sheep breed for large-scale extensive range production systems. Flocking behavior or “flockability”, a measure gregariousness, critical to produce extensive, herded management An evaluation Western U.S. environment compared traditional range-adapted Rambouillet underway. The objective was compare flockability range-reared ewes during summer grazing season using GPS collars. Flockability measured...
ABSTRACT Aims Persistent land use change throughout the North American Great Plains increases need to maintain and improve ecosystem service delivery from remaining rangelands meet production conservation goals. Vegetation structure is an property influenced by management that has site selection implications for wildlife livestock. In this study, we investigated efficacy of patch‐burn grazing increase structural heterogeneity on semi‐arid post‐Conservation Reserve Program (CRP) grasslands in...
Social conflict over rangeland-use priorities, especially near protected areas, has long pitted environmental and biodiversity conservation interests against livestock livelihoods. Social–ecological limits management adaptation creativity while reinforcing social disciplinary divisions. It can also reduce rancher access to land negatively affect wildlife conservation. Communities increasingly expect research organizations address complex dynamics improve opportunities for multiple ecosystem...
Ecologists have used Global Positioning Systems (GPS) to track animals for 30 years. Issues today include logging frequency and precision in estimating space use travel distances, as well battery life cost. We developed a low-cost (~US$125), open-source GPS datalogger based on Arduino. To test the system, we collected positions at 20-s intervals several 1-week durations from cattle sheep rangeland North Dakota. tested two questions of broad interest ecologists who collars animal movements:...
