What is a biocrust? A refined, contemporary definition for a broadening research community

Bettina Weber, Jayne Belnap, Burkhard Büdel, Anita J. Antoninka, more

Biological Reviews > 97 > 5 > 1768 - 1785

Studies of biological soil crusts (biocrusts) have proliferated over the last few decades. The biocrust literature has broadened, with more studies assessing and describing the function of a variety of biocrust communities in a broad range of biomes and habitats and across a large spectrum of disciplines, and also by the incorporation of biocrusts into global perspectives and biogeochemical models...

Community composition influences ecosystem resistance and production more than species richness or intraspecific diversity

Matthew A. Bowker, M. Cristina Rengifo‐Faiffer, Anita J. Antoninka, Henry S. Grover, more

Oikos > 130 > 8 > 1399 - 1410

Biodiversity describes the variety of life and may influence properties and processes of ecosystems, such as biomass production and resistance to disturbance. We investigated the effects of multiple facets of biodiversity – species richness and composition of the community, and intraspecific diversity in two key species – on both production and resistance of experimentally‐assembled biological soil...

A practical guide to measuring functional indicators and traits in biocrusts

Max Mallen‐Cooper, Matthew A. Bowker, Anita J. Antoninka, David J. Eldridge

Restoration Ecology > 28 > S2 > S56 - S66

Biocrusts are multifunctional communities that are increasingly being used to restore degraded or damaged ecosystems. Concurrently, restoration science is shifting away from the use of purely structural metrics, such as relative abundance, to more functional approaches. Although biocrust restoration technology is advancing, there is a lack of readily available information on how to monitor biocrust...

Inoculation and habitat amelioration efforts in biological soil crust recovery vary by desert and soil texture

Akasha M. Faist, Anita J. Antoninka, Jayne Belnap, Matthew A. Bowker, more

Restoration Ecology > 28 > S2 > S96 - S105

As dryland degradation continues, it is increasingly important to understand how to effectively restore biocrust communities. Potential techniques include the addition of biocrust inoculum to accelerate biocrust recovery. Enhanced erosion typical of degraded environments creates a challenge for these approaches, due to loss by wind or water and burial by saltating particles. To retain and protect...

Improving field success of biocrust rehabilitation materials: hardening the organisms or softening the environment?

Matthew A. Bowker, Anita J. Antoninka, Peter F. Chuckran

Restoration Ecology > 28 > S2 > S177 - S186

Drylands are a widely degraded biome characterized by low productivity and high abiotic stress. Biological soil crust (biocrust) inoculants hold promise as a rehabilitation material in drylands, useful for boosting ecosystem functions including stabilization of eroding soil surfaces. However, biocrust materials cultivated ex situ by humans inconsistently establish under field conditions. We tested...

Towards a predictive framework for biocrust mediation of plant performance: A meta‐analysis

Caroline A. Havrilla, V. Bala Chaudhary, Scott Ferrenberg, Anita J. Antoninka, more

Journal of Ecology > 107 > 6 > 2789 - 2807

Understanding the importance of biotic interactions in driving the distribution and abundance of species is a central goal of plant ecology. Early vascular plants likely colonized land occupied by biocrusts — photoautotrophic, surface‐dwelling soil communities comprised of cyanobacteria, bryophytes, lichens and fungi — suggesting biotic interactions between biocrusts and plants have been at play...

Insolation and disturbance history drive biocrust biodiversity in Western Montana rangelands

Rebecca A. Durham, Kyle D. Doherty, Anita J. Antoninka, Philip W. Ramsey, more

Plant and Soil > 2018 > 430 > 1-2 > 151-169

Background and Aims Biological soil crust (biocrust) communities, though common and important in the intermountain west, have received little research attention. There are gaps in understanding what influences biocrust species’ abundance and distributions in this ecoregion. Climatic, edaphic, topographic, and biotic forces, in addition to anthropogenic disturbance can all influence the biocrust. ...

Biocrust moss populations differ in growth rates, stress response, and microbial associates

Kyle D. Doherty, Matthew A. Bowker, Anita J. Antoninka, Nancy C. Johnson, more

Plant and Soil > 2018 > 429 > 1-2 > 187-198

Aims A growing body of research supports the feasibility of biocrust rehabilitation. Identifying populations of key species that are amenable to cultivation and that are resilient in rehabilitation contexts would advance the efficacy of these technologies. Here we investigate the growth and stress response of the cosmopolitan biocrust moss, Syntrichia ruralis. Methods We sampled populations of S. ruralis...

Corrigendum to “The hidden Serengeti—Mycorrhizal fungi respond to environmental gradients” [Pedobiol. J. Soil Ecol. 58 (5–6), September–November (2015) 165–176]

Rapid ex situ culture of N-fixing soil lichens and biocrusts is enhanced by complementarity

Matthew A. Bowker, Anita J. Antoninka

Plant and Soil > 2016 > 408 > 1-2 > 415-428

Background and aims Rehabilitation of biological soil crusts (biocrusts) in degraded drylands may facilitate ecosystem recovery. In order to rehabilitate biocrusts, ex situ culture methods for biocrust organisms must be optimized so that biocrusts may be grown in sufficient quantities to be reintroduced into degraded areas. Our goal was to improve these culture methods. Methods We cultured six biocrust...

The hidden Serengeti—Mycorrhizal fungi respond to environmental gradients

Anita J. Antoninka, Mark E. Ritchie, Nancy C. Johnson

Pedobiologia - Journal of Soil Ecology > 2015 > 58 > 5-6 > 165-176

Mycorrhizas influence plant productivity, community composition, nutrient dynamics and soil structure, yet the factors determining the abundance and diversity of these symbioses in natural ecosystems are poorly understood. We studied arbuscular mycorrhizal (AM) fungi (Glomeromycota) in long-term grazed and un-grazed plots at eight sites forming natural gradients of soil properties and rainfall in...
