We monitored the decomposition of mixed leaf litter (Quercus spp., Carya spp., and Pinus echinata) in a Missouri Ozark forest eight years after experimental harvest. Leaf littermass losses and changes in carbon chemistry (extractive, acid soluble, and acid insoluble fractions) were measured over 32 months in field incubations to determine the effects of litter composition and standmanipulation ...
Ecohydrology 2017;e1825. https://doi.org/10.1002/eco.1825 Abstract Topography may mitigate drought effects on vegetation along a hillslope gradient through redistribution of soil moisture. We examined the interaction of topography, climate, soil moisture, and transpiration in a low‐elevation, mixed‐hardwood forest in the southern Appalachian Mountains. The effects of meteorological variation (w...
Woodland management strategies are increasingly focused on reducing non-native plant species. However, changing the species profile of a habitat can have highly disruptive effects on local ecosystems. An isolated woodland containing a population of the northern wood-ant Formica lugubris ZETTERSTEDT, 1838 was used as a case study to predict the effects on the ants of proposed woodland management...
Truffles are hypogeous ectomycorrhizal (EM) fungi belonging to the genus Tuber. Although outplanting of truffle-inoculated host plants has enabled the realization of productive orchards, truffle cultivation is not yet standardized. Therefore, monitoring the distribution of fungal species in different truffle fields may help us to elucidate the factors that shape microbial communities and influe...
Alteration of the fire regime in upland oak–hickory (Quercus L. spp.–Carya Nutt. spp.) forests Central Hardwood Region is a major factor for current shifts species’ composition and oak recruitment regeneration failures. The reintroduction into these ecosystems requires better understanding effects on co-occurring competitors. First-order (i.e., during immediately after) red maple (Acer rubrum L...
Abstract Numerous forests in the eastern United States have been degraded due to past exploitative timber harvesting known as high grading. High graded forest stands may not improve without active rehabilitation and require targeted silvicultural treatments. This study focuses on mixed-oak (mixed-Quercus spp.) aims develop a model that can identify grading determine modifications management rec...
Chloroplast DNA (cpDNA) is frequently used for species demography, evolution, and species discrimination of plants. However, the lack of efficient and universal markers often brings particular challenges for genetic studies across different plant groups. In this study, chloroplast genomes from two closely related species (Quercus rubra and Castanea mollissima) in Fagaceae were compared to explo...
