Pollinator seed mixes are phenologically dissimilar to prairie remnants

open access: yesRestoration Ecology, Volume 33, Issue 3, March 2025.
Native seed mixes are widely available to create pollinator habitat. One approach to understand the efficacy of pollinator seed mixes is to compare them to species found in high‐quality natural areas. Using plant species presence data from published lists, we compared weekly blooming richness between 196 seed mixes explicitly designed to support ...

Phosphorous fertilization and soil pH affect the growth of deciduous trees in a temperate hardwood forest

open access: yesEcosphere, Volume 16, Issue 2, February 2025.
Abstract Forest ecosystems with altered nutrient limitations are a common legacy of acidic deposition in North America. Continued acidic deposition has lowered soil pH and revealed phosphorus (P) limitations in many temperate forest ecosystems. Previous studies exploring P limitations or co‐limitations are often short term, and thus may potentially ...
