Seed and seedling traits have strong impacts on establishment of a perennial bunchgrass in invaded semi-arid systems

Publications Posted on: October 02, 2019
Many restoration projects use seeds to found new populations, and understanding phenotypic traits associated with seedling establishment in disturbed and invaded communities is important for restoration efforts world-wide. Focusing on the perennial grass Elymus elymoides, a native species common to sagebrush steppe communities in the Western United States, we asked if seed and seedling traits could predict field establishment.

Handbook of standardized protocols for collecting plant modularity traits

Publications Posted on: September 26, 2019
Plant modularity traits relevant to functions of on-spot persistence, space occupancy, resprouting after disturbance, as well as resource storage, sharing, and foraging have been underrepresented in functional ecology so far. This knowledge gap exists for multiple reasons. First, these functions and related traits have been considered less important than others (e.g., resource economics, organ-based traits).

Does burn severity affect plant community diversity and composition in mixed conifer forests of the United States Intermountain West one decade post fire?

Publications Posted on: September 14, 2019
Background: Wildfire is an important ecological process in mixed conifer forests of the Intermountain West region of the USA. However, researchers and managers are concerned because climate warming has led to increased fire activity in recent decades.

Rodent seed predators and a dominant grass competitor affect coexistence of co-occurring forb species that vary in seed size

Publications Posted on: September 26, 2018
Propagule size and number often vary by several orders of magnitude among co-occurring plant species. Explaining the maintenance of this variation and understanding how propagule size contributes to coexistence remain a central challenge for community ecologists.

Emergence and early survival of early versus late seral species in Great Basin restoration in two different soil types

Publications Posted on: October 07, 2015
Comparing emergence and survival probabilities, early seral natives generally outperformed late seral natives when growing with exotics and had earlier emergence timing, although results differed among functional groups and soil types. In contrast, survival probabilities did not differ between the early and late seral mixes when growing without exotics.

First-year establishment, biomass and seed production of early vs. late seral natives in two medusahead (Taeniatherum caput-meducae) invaded soils

Publications Posted on: October 03, 2014
Re-seeding efforts to restore or rehabilitate Great Basin rangelands invaded by exotic annual grasses are expensive and have generally achieved limited success. There is a need to identify new strategies to improve restoration outcomes.

A multi-trait test of the leaf-height-seed plant strategy scheme with 133 species from a pine forest flora

Publications Posted on: April 04, 2012
Plants are multifaceted organisms that have evolved ecological strategies for sustaining populations in resource-limited environments (Grime 1979; Craine 2009). Plant strategies can be quantified by measuring functional traits (Grime et al. 1997; Reich et al. 2003), which are the properties of plants that impact plant fitness (Violle et al. 2008) and ecosystem processes (Lavorel & Garnier 2002).

Integrated reclamation: Approaching ecological function?

Publications Posted on: September 25, 2009
Attempts to reclaim arid and semiarid lands have traditionally targeted plant species composition. Much research attention has been directed to seeding rates, species mixes and timing of seeding. However, in order to attain functioning systems, attention to structure and process must compliment existing efforts. We ask how to use a systems approach to enhance reclamation success.
