Roxanne Hastings: A Life Exploring Nature's Minute Marvels and Vast Horizons

1956 – 2016

Botanist, moss expert, and photographer who bridged science and art

A Legacy in Moss and Microscope

Roxanne Hastings (28 June 1956–2 June 2016) dedicated her life to deciphering nature's quietest stories—from the minute mosses clinging to desert rocks to the spiritual boundaries shaping human connection with land. Her career spanned 26 years at the Royal Alberta Museum, where she served as curator of botany and acting head of life sciences before retiring in 20151 . Hastings became a renowned North American expert on the taxonomy, systematics, and biogeography of the widespread desert moss genus Grimmia, contributing significantly to our understanding of these resilient yet overlooked organisms1 .

This tribute celebrates Hastings' dual legacy as both a meticulous scientist and creative spirit, whose work bridged the gap between specialized botanical research and the human experience of place and belonging.

During her tenure, she co-curated the Wild Alberta Gallery, helping to create exhibits that translated complex ecological relationships into engaging public experiences1 . As curator of botany, she oversaw the preservation and study of the museum's plant collections, ensuring these valuable scientific resources would remain available for future research.

Post-Retirement Work

Even after her retirement from the museum in 2015, Hastings continued her scientific work as a visiting scholar with the Cryptogamic Herbarium in the University of Alberta's Department of Biological Sciences, where she maintained her research on moss systematics1 . This dedication to her field demonstrates a lifelong commitment to scientific inquiry that extended well beyond conventional career boundaries.

Groundbreaking Research on Grimmia Moss

Hastings established herself as a North American expert on the genus Grimmia, a group of mosses particularly adapted to survive in harsh desert environments1 . Her specialized work focused on:

Taxonomy

Identifying and classifying different species within this challenging genus

Systematics

Understanding the evolutionary relationships between Grimmia species

Biogeography

Mapping the distribution patterns of these mosses across landscapes

Her expertise in these areas filled important gaps in our understanding of how these seemingly fragile organisms not only survive but thrive in some of North America's most demanding habitats.

In-Depth Look: A Key Experiment in Plant Ecology

While Hastings built her reputation on moss research, her scientific curiosity extended to broader ecological questions. Her collaborative work on plant competition, exemplified by a 2016 study published in Plant Ecology, provides a compelling case study of her rigorous approach to ecological investigation.

Methodology: Untangling Competition and Seed Limitation

The research addressed a fundamental question in ecology: why do native annual plants typically exhibit low abundances in grasslands invaded by exotic species? Hastings and her colleagues designed a sophisticated field experiment to test two competing hypotheses:

  1. Competition: Established exotic grasses directly suppress native annuals through resource competition
  2. Seed limitation: Native annual populations are limited by inadequate seed dispersal rather than competition
Experimental Design

The researchers established multiple experimental field plots where they manipulated both competition from exotic grasses and seed availability of native annuals.

Results and Analysis: Revealing Complex Ecological Interactions

The experiment yielded nuanced insights into grassland ecology. The key findings revealed:

Table 1: Native Annual Plant Responses to Experimental Treatments
Treatment Germination Rate Survival to Reproduction Seed Production
Control (no manipulation) Low Moderate Low
Grass removal only Moderate increase Significant increase Moderate increase
Seed addition only Significant increase No significant change Moderate increase
Grass removal + seed addition Highest increase Highest increase Highest increase

The data demonstrated that both competition and seed limitation operate simultaneously to influence native annual populations. The most dramatic responses occurred in plots where both exotic grasses were removed and native seeds were added, suggesting these factors interact synergistically.

Table 2: Relative Impact of Ecological Factors on Native Annuals
Factor Impact on Establishment Impact on Reproduction Overall Significance
Competition with exotics High Moderate High
Seed availability Moderate Moderate Moderate
Microsite suitability Low High Moderate
Interaction of factors Very high Very high Very high

Hastings' analysis provided valuable insights for restoration ecology, suggesting that effective management requires addressing multiple constraints simultaneously. This research exemplified her ability to design experiments that captured ecological complexity while yielding practical conservation implications.

The Scientist's Toolkit: Essential Research Materials and Methods

Hastings' research, particularly on desert mosses, required specialized equipment and methodologies. The following toolkit represents essential materials she would have utilized throughout her scientific career.

Beyond the Laboratory: The Photographic Journey

Perhaps less widely known but equally significant was Hastings' creative pursuit through photography. In her retirement, she embarked on an ambitious personal project titled "Boundaries and Borderlands," which examined spatial and spiritual boundaries in Europe and Asia1 .

This photographic exploration represented a natural extension of her scientific work, which had always concerned itself with how organisms inhabit and adapt to different environments, territories, and ecological niches. Where her scientific research mapped the distribution of moss species across physical landscapes, her photography sought to document the intangible boundaries that shape human existence and spiritual practice.

The project demonstrated Hastings' remarkable capacity to synthesize different ways of knowing, bridging the empirical precision of science with the expressive potential of art.

This interdisciplinary approach characterized her lifelong commitment to understanding the many ways life—both plant and human—inhabits, divides, and connects across spaces physical and conceptual.

A Lasting Legacy: Mosses, Museums, and Meaning

Roxanne Hastings' multifaceted career leaves behind a rich legacy that continues to inspire scientists, museum professionals, and artists alike. Her contributions to bryology advanced our understanding of some of the planet's most resilient yet understudied plants.
