Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

Soil Metabarcoding Helps Identify Recalcitrant Taxa From Chaparral Seed Banks

open access: yesJournal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Soil seed banks preserve plant diversity, but traditional germination methods often miss dormant or hard‐to‐germinate species. Our study tested metabarcoding as an alternative, finding that DNA‐based sequencing was more reliable than RNA and that water treatments influenced sequencing results.

Earthworm abundances in endophyte-infected tall fescue pastures in Northwest Arkansas [PDF]

open access: yes, 2008
The ecology of organisms that co-evolve within an ecosystem is likely to be distinct from that involving organisms recently introduced into an area. To better understand the relationship of earthworms with endophyte-infected tall fescue, earthworms in ...

Nutrient addition and herbivore exclusion alter plant traits and biomass via distinct mechanisms: intraspecific variability vs species turnover

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2251-2262, March 2026.
Summary Soil nutrients and vertebrate herbivory are key ecological factors with opposite and interactive effects on grassland plant traits and biomass. Partitioning trait changes into species turnover and intraspecific change provides a mechanistic linkage between trait shifts and biomass responses.

Nucleolar dominance arises in Spartina homoploid hybrids and persists after allopolyploidization

open access: yesThe Plant Journal, Volume 125, Issue 5, March 2026.
Significance Statement Evolution of nucleolar dominance in Spartina anglica since its origin c. 150 years ago. mC, cytosine methylation; NOR, nucleolar organizer regions. rDNA resides within the NORs. Spartina anglica C.E. Hubbard presents an iconic allopolyploid species that formed only 150 years ago, spreading worldwide since then.
