Role of propagule pressure and priority effects on seedlings during invasion and restoration of shrub-steppe

Creator:: Schantz, Merilynn C., Sheley, Roger L., and James, Jeremy J.
Abstract:: Plant invasion and restoration outcomes are largely driven by the timing and magnitude of seed dispersal, and by the performance of dispersed species in an environment. Because seed dispersal controls recruitment of newly arriving species and facilitates safe site occupation, assembly will differ depending on seed dispersal processes and variable...

Do key dimensions of seed and seedling functional trait variation capture variation in recruitment probability?

Creator:: Larson, Julie E., Sheley, Roger L., Hardegree, Stuart P., Doescher, Paul S., and James, Jeremy J.
Abstract:: Seedling recruitment is a critical driver of population dynamics and community assembly, yet we know little about functional traits that define different recruitment strategies. For the first time, we examined whether trait relatedness across germination and seedling stages allows the identification of general recruitment strategies which share core functional attributes...

Seed and seedling traits affecting critical life stage transitions and recruitment outcomes in dryland grasses

Creator:: Larson, Julie E., Sheley, Roger L., Hardegree, Stuart P., Doescher, Paul S., and James, Jeremy J.
Abstract:: 1. Seeding native plants is a key management practice to counter land degradation across the globe, yet the majority of seeding efforts fail, limiting our ability to accelerate ecosystem recovery. 2. Recruitment requires transitions through several seed and seedling stages, some of which may have overriding influences on restoration outcomes....

Ecosystem effects of shell aggregations and cycling in coastal waters: an example of Chesapeake Bay oyster reefs

Creator:: Waldbusser, George G., Powell, Eric N., and Mann, Roger
Abstract:: Disease, overharvesting, and pollution have impaired the role of bivalves on coastal ecosystems, some to the point of functional extinction. An underappreciated function of many bivalves in these systems is shell formation. The ecological significance of bivalve shell has been recognized; geochemical effects are now more clearly being understood. A...

Abstract:: Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased phosphorus inputs degraded water quality and reduced central basin hypolimnetic oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms and contributed to the extirpation of important benthic macroinvertebrate...
