Sooty mangabeys are Old World primates from the Upper Guinea Rainforests of West Africa. They suffer from habitat degradation due to deforestation and hunting for the bush-meat trade. Tiwai Island and adjacent small islands are a small protected area surrounded by the Moa River that is known for its high diversity of primate species. We evaluated the occupancy and abundance of sooty mangabeys on Tiwai Island and the surrounding islands using camera traps during 2008–2011. Over two seasons, we obtained a naïve occupancy rate of 0.77 for Tiwai Island but only 0.19 for surrounding smaller islands. We used Abundance-Induced Heterogeneity …

The contiguous grasslands of the Sandhills region in Nebraska, USA, provide habitat for two sympatric, grassland-obligate species of grouse, the greater prairie-chicken (Tympanuchus cupido pinnatus) and the plains sharp-tailed grouse (Tympanuchus phasianellus jamesi). Collectively referred to as prairie grouse, these birds are monitored and managed jointly by wildlife practitioners who face the novel challenge of conserving historically allopatric species in shared range. We reconstructed region-wide and route-specific prairie grouse population trends in the Sandhills, using a 63-year timeseries of breeding ground counts aggregated from old reports and paper archives. Our objective was to repurpose historical data …

The cross-scale resilience model suggests that system-level ecological resilience emerges from the distribution of species’ functions within and across the spatial and temporal scales of a system. It has provided a quantitative method for calculating the resilience of a given system and so has been a valuable contribution to a largely qualitative field. As it is currently laid out, the model accounts for the spatial and temporal scales at which environmental resources and species are present and the functional roles species play but does not inform us about how much resource is present or how much function is provided. In …
Impacts Of Strategic Grazing And Fire On Soil Seed Bank Heterogeneity In Mixed-Grass Prairie, Kassidy Weathers, Lan Xu, Patricia Johnson
Impacts Of Strategic Grazing And Fire On Soil Seed Bank Heterogeneity In Mixed-Grass Prairie, Kassidy Weathers, Lan Xu, Patricia Johnson
Natural Resource Management Faculty Publications
Native plant communities in the Northern Great Plains evolved under periodic fire and substantial grazing pressure from native herbivores, two main drivers maintaining the heterogeneity of grassland ecosystems. However, contemporary management practices focus on maximizing livestock production through fire suppression and uniform grazing strategies, resulting in decreased vegetation heterogeneity, species richness, wildlife habitat, and biodiversity. Objectives of this study were to evaluate and compare the effectiveness of patch-burn grazing (PBG) and winter-patch grazing (WPG) managements on soil seed bank heterogeneity in terms of species 1) richness, 2) composition, 3) abundance, and 4) diversity. Two soil cores (10-cm dia × 10-cm …

Long-billed Curlews (Numenius americanus) are shorebirds of high conservation concern in North America. Populations have declined in the last 150 yr primarily due to habitat loss and conversion. We conducted a 2-yr study to estimate the density and statewide abundance of breeding Long-billed Curlews in Nebraska during 2008 and 2009. Surveys were conducted during the prenesting period in April when Long-billed Curlews were likely to be detected. We used a simple random sample of roadside survey routes (N = 39), each consisting of 40 5-min point-counts at 800-m intervals. We modeled detection probability and found that wind …

Impacts Of House Mice On Crops In Australia - Costs And Damage, Peter R. Brown, Grant R. Singleton
Impacts Of House Mice On Crops In Australia - Costs And Damage, Peter R. Brown, Grant R. Singleton
Human Conflicts with Wildlife: 2002 Symposium
Rodents cause serious losses to crops in many different parts of the world. The house mouse (Mus domesticus, Schwarz and Schwarz 1943) is a serious pest to agriculture in Australia. The impacts of house mouse damage to crops in Australia were examined. Plagues of mice (>1,000 mice/ha) cause enormous economic and social stress to rural communities in Australia. The mouse plague in 1993/94 caused about US$60 million in damage to crops, intensive livestock industries, and rural communities. The impact of mouse plagues is generally well understood, but there is a dearth of knowledge about the relationship between …
