The potential distribution and disappearing of Yunnan snub-nosed monkey: Influences of habitat fragmentation
Get PDFAnalysis of environmental variables and organism occurrence records offers insight that can be used to predict potential distribution areas and habitat fragmentation. For large landscapes, modeling is the most convenient and effective way to conduct habitat research. Two species distribution models, BIOMOD2 and FRAGSTATS 4.2, were given data on environmental variables and organism occurrence records as input and used to predict the potential suitable habitat and habitat fragmentation for the Yunnan snub-nosed monkey (Rhinopithecus bieti). Our results estimated the total area of potentially suitable habitat for R. bieti as 7412.82 km2, but only 4164.58 km2 was found to be inhabited by R. bieti. We found that the main land cover type in the potential suitable distribution area of R. bieti was evergreen needle-leaf forest (6153.95 km2, 83.02%). Comparison of inhabited and suitable but uninhabited habitats showed that areas actually inhabited by R. bieti had a lower patch density (PD) and higher largest patch index (LPI) than uninhabited habitats only in evergreen needle-leaf forest. The potential suitable habitats of R. bieti has increased significantly, but the actual distribution has shrunk from 1997 to 2017. Although the government has made great progress in protecting R. bieti, logging that took place before the regulations and the boundary effect of roads and rivers resulted in the local extinction of R. bieti in some potentially suitable areas. In view of this, we propose to establish a national park for Yunnan snub-nosed monkeys. We also suggest protecting the potentially suitable but currently empty habitats for later release of R. bieti. Successfully reintroducing R. bieti into areas where it formerly lived will require continual and careful habitat monitoring.PublishedYe
Raw and post-processed ensemble forecasts of crop reference evapotranspiration over the CONUS produced with NWP
No full textDatabase with raw and post-processed ensembles of summer crop reference evapotranspiration forecasts over the CONUS based on numerical weather predictions (NWP). The forecasts consider single or multi-model NWP from The International Grand Global Ensemble (TIGGE), including the European Centre for Medium-Range Weather Forecasts (ECMWF), the National Centers for Environmental Prediction Global Forecast System (NCEP), and the United Kingdom Meteorological Office forecasts (UKMO).

Authentic Professional Learning: Creating Faculty Development Experiences through an Assessment Institute
Get PDFThis case study analyzes experiences of participants in an Assessment Institute (AI) for faculty development on ePortfolio. In earlier research on the AI, findings showed that focused faculty development increased instructor confidence in teaching and learning with ePortfolio. The present study expanded the initial research by including participant data from a second session of the AI, and exploring the research through a qualitative lens using transformative learning as the framework. Strong support for the use of dialogue and critical reflection in faculty development were found during the research. Our findings suggest that professional development environments that encourage transformative learning by means of discussion, sharing of different perspectives, and reflections on implementation and best practices yield positive results. These factors can inform researchers and practitioners interested in structuring similar faculty development initiatives in the higher education environment.PublishedYe

Frequency of Occurrence and Population-Dynamic Consequences of Different Forms of Density-Dependent Emigration
Get PDFEmigration is a fundamental process affecting species' local, regional, and large-scale dynamics. The paradigmatic view in ecology is that emigration is density independent (DIE) or positive density dependent (1DDE). However, alternative forms are biologically plausible, including negative (2DDE), U-shaped (uDDE), and hump-shaped (hDDE) forms. We reviewed the empirical literature to assess the frequency of different forms of density-dependent emigration and whether the form depended on methodology. We also developed a reaction-diffusion model to illustrate how different forms of DDE can affect patch-level population persistence. We found 145 studies, the majority representing DIE (30%) and 1DDE(36%). However, we also regularly found 2DDE (25%) and evidence for nonlinear DDE(9%), including one case of uDDE and two cases of hDDE. Nonlinear DDE detection is likely hindered by the use of few density levels and small density ranges. Based on our models, DIE and 1DDE promoted stable and persistent populations. uDDE and 2DDE generated an Allee effect that decreases minimum patch size. Last, 2DDE and hDDE models yielded bistability that allows the establishment of populations at lower densities. We conclude that the emigration process can be a diverse function of density in nature and that alternative DDE forms can have important consequences for population dynamics.PublishedYe
