Evidence of Nitrogen and Phosphorus Limitation in Longleaf Pine Savanna Understories

Alyssa L. Young, Kathryn J. Bloodworth, Sally E. Koerner

ABSTRACT Due to anthropogenic pressures, only 3% of the historic extent of the biodiverse longleaf pine ecosystem remains, much of which is degraded. Fire is necessary for maintaining longleaf pine savanna structure, function, and biodiversity; however, it also creates resource constraints, as …

Characterizing the Drivers of Northern Mixed-Grass Prairie Plant Community Composition

Shelley Bennett, Kathryn J. Bloodworth, Sarah J.M. Alley, Elizabeth Blake et autres

Northern mixed-grass prairies are recognized for their high biodiversity but are becoming increasingly threatened by conversion to agricultural rangeland. To determine how grazing by cattle or reintroduced bison may impact these plant communities, we examined the primary drivers of northern mixed-grass prairie …

Global impoverishment of natural vegetation revealed by dark diversity

Meelis Pärtel, Riin Tamme, Carlos P. Carmona, Kersti Riibak et autres

. In the sampled regions with a minimal human footprint index, an average of 35% of suitable plant species were present locally, compared with less than 20% in highly affected regions. Besides having the potential to uncover overlooked threats to biodiversity, dark …

Global impoverishment of natural vegetation revealed by dark diversity

Kimberly J. Komatsu, Marie Konečná, Ene Kook, Lotte Korell et autres

Anthropogenic biodiversity decline threatens the functioning of ecosystems and the many benefits they provide to humanity. As well as causing species losses in directly affected locations, human influence might also reduce biodiversity in relatively unmodified vegetation if far-reaching anthropogenic effects trigger local …

Plant size, latitude, and phylogeny explain within-population variability in herbivory

Moria Robinson, Philip G. Hahn, Brian D. Inouye, Nora Underwood et autres

Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system is thought to influence most aspects of plant-herbivore biology, from ecological stability to plant defense evolution. Our understanding of …

Effects of white‐tailed deer exclusion on the plant community composition of an upland tallgrass prairie ecosystem

Kathryn J. Bloodworth, Mark E. Ritchie, Kimberly J. Komatsu

Abstract Questions Grasslands support ecosystem services, promote diversity, and assist in carbon sequestration. However, grasslands worldwide are diminishing in area, and understanding the drivers shaping the remaining grasslands is critical for their maintenance. The North American tallgrass prairie covers approximately 13% of …
