We use data from a representative sample and a sample of convenience to investigate how willingness to pay (WTP) for increased cultural (recreational) use of an ecologically unique site differs across the two groups. We find mixed evidence of differences in WTP estimates between the two samples depending on the survey attribute. Where differences exist, the most effective selection correction mechanism is the ordered probit with weights. Our results suggest caution about extrapolating...AuthorsSonja Kolstoe, Brian Vander Naald, Alison CohanKeywordsSourceEcosystem Services. 55(1): 101420.Year2022
- Savannas cover a fifth of the land surface and contribute a third of terrestrial net primary production, accounting for three-quarters of global area burned and more than half of global fire-driven carbon emissions1,2,3. Fire suppression and afforestation have been proposed as tools to increase carbon sequestration in these ecosystems2,4. A robust quantification of whole-ecosystem carbon storage in savannas is lacking however, especially under altered fire regimes. Here we provide one of the first direct estimates of whole-ecosystem carbon response to more than 60 years of fire exclusion...AuthorsYong Zhou, Jenia Singh, John Butnor, Corli Coetsee, Peter B.

- \International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated fungi and insects is needed. We present records of endophytic fungi and insects in twigs of 17 angiosperm and gymnosperm genera, from 51 locations in 32 countries worldwide. Endophytic fungi were characterized by highthroughput sequencing of 352 samples from 145 tree species in 28 countries. Insects were reared from 227 samples of 109 tree species in 18 countries and...AuthorsIva Franić, Simone Prospero, Kalev Adamson, Eric Allan, Fabio Attorre, Marie Anne Auger-Rozenberg, Sylvie Augustin, Dimitrios Avtzis, Wim Baert, Marek Barta, Kenneth Bauters, Amani Bellahirech, Piotr Boroń, Helena Bragança, Tereza Brestovanská, May Bente Brurberg, Treena Burgess, Daiva Burokienė, Michelle Cleary, Juan Corley, David R.

- The longevity of a single 22.4 Mg·ha-1 application of dolomitic limestone at four northern hardwood stands was evaluated over 30 years (1986–2016) to determine whether changes in soils, foliage, and tree growth were sustained on the unglaciated Allegheny Plateau in northern Pennsylvania, USA. In limed plots, soils, sampled to 45–55 cm depth, and sugar maple (Acer saccharum Marsh.) and black cherry (Prunus serotina Ehrh.) foliage had significantly (P ≤ 0.05) greater concentrations of calcium (Ca) and magnesium (Mg) through 2016 compared with samples from unlimed plots. Ca and Mg capitals...AuthorsRobert P. Long, Scott Bailey, Stephen Horsley, Thomas J. HallKeywordsSourceCanadian Journal of Forest ResearchYear2022
- The plains spotted skunk (Spilogale interrupta) is of conservation concern because of widespread population declines and is being considered for listing under the United States Endangered Species Act. Although the taxon is relatively rare and difficult to study, recent research and reports provided some information about spotted skunks in Arkansas and Missouri, USA. Using this information, we employed full and simplified multivariate species distribution models to evaluate cover type associations and identify regions of high predicted presence for plains spotted skunks. The simple model...AuthorsSummer H. LaRose, Maggie P. MacPherson, Damon B. Lesmeister, H. Mundy Hackett, Roger W. Perry, D. Blake Sasse, Matthew E.

- Fire is a key determinant of vegetation structure and composition in ecosystems worldwide and is therefore an important management tool. The “pyrodiversity hypothesis”, which postulates that biodiversity will increase as fire diversity increases, remains largely untested for pollinators, a group of high conservation concern. We tested the relationship between pollinator diversity and pyrodiversity based on a decade of burn history in Florida, as well as testing other parameters, including burn frequency, the percentage of area burned during the year of sampling, canopy openness, and...AuthorsMichael Ulyshen, J Kevin Hiers, Scott Pokswinksi, Conor FairSourceFrontiers in Ecology and the EnvironmentYear2022
- Invasive non-native woody shrubs pose a major threat to forested ecosystems in many parts of the world and there is an urgent need for research on the restoration and recovery of these areas. We studied patterns of tree growth and regeneration 13 years after the experimental eradication (by chainsaw or mulching machine followed by herbicide treatments) of Ligustrum sinense Lour. (Chinese privet) from riparian forests in Georgia, United States. We also followed the recovery of bee and butterfly populations using sites with no history of privet invasion as a reference. By the end of the...AuthorsMichael Ulyshen, Scott Horn, James HanulaKeywordsSourceFrontiers in Ecology and EvolutionYear2022
- Restoration of savanna ecosystems within their historic range is expected to increase provision of ecosystemservices to resident human populations. However, the benefits of restoration depend on the degree to which ecosystems and their services can be restored, the rate of restoration of particular services, and tradeoffs in services between restored ecosystems and other common land uses.We use a chronosequence approach to infer multi-decadal changes in ecosystem services undermanagement aimed at restoring fire-dependent pine savannas, including the use of frequent prescribed fire,...AuthorsCinnamon M.

- The increased abundance of historically rare native tree species is symptomatic of land-use change, which causes ecosystem regime shifts. I tested for an association between mean agricultural area, a proxy for land-use change, and native tree species. I first modeled agricultural area during the years 1850 to 1997 and the historical and current percent composition of tree genera, along with the dissimilarity and difference between the historical and current composition, for the northern part of the eastern U.S. I then modeled agricultural area and current genera and species for the eastern...AuthorsBrice HanberryKeywordsSourceLand. 11: 161.Year2022
- Ancient giant sequoias Sequoiadendron giganteum (Lindl.) J. Buchholz are highly valued trees with limited distribution. They are the most massive trees on earth, and they have exceptional longevity (>3,000 years). Given their extraordinary resilience to wildfire, insects, and disease, most managers hoped giant sequoias would be resistant to anthropogenic change. However, the warming climate and fire exclusion-caused fuel build-up has dramatically increased the amount of high-intensity wildfire in giant sequoia groves since 2015. To better understand recent wildfire effects on large, legacy...AuthorsKristen L. Shive, Amarina Wuenschel, Linnea J. Hardlund, Sonia Morris, Marc D. Meyer, Sharon M.
