Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Crop insurance and irrigation behavior: The conditional role of pumping costs

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Excessive water use for irrigation can accelerate the depletion of water resources, undermining agriculture's resilience to weather‐related shocks. Understanding how farmers make water use decisions is essential for developing effective water management policies.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Transcript modification: A potential nutrient‐conserving strategy for polyploid plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Due to greater cell and nucleic acid nutrient requirements, polyploids have been hypothesized to be more constrained than related diploids in terms of cell synthesis and biomass accumulation when soil nutrients are limited. Methods Here, we grew autotetraploid and diploid Solidago gigantea plants in soils enriched or limited with ...

The biogeography of the Amazonian tree flora

open access: yesCommunications Biology
We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover.

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

A large phylogenetic tree for euphyllophytes

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Molecular datasets for estimating phylogenetic trees increasingly include more species and gene regions, and trees are often constructed using backbone phylogenies, subtrees, and other techniques to address the challenges of large dataset size.

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.
