Congratulations, Doctor Ojascastro! James successfully defended his dissertation against wily attackers and earned massive Ph.D! James’s dissertation is truly interdisciplinary, combining community ecology, global change biology, and ethnography all to examine the long history and contemporary conservation needs of the practice of papermaking around the world. His main thesis advisor was Dr. Robbie Hart, but …

Beyond climate? Factors determining fruiting and flowering phenology across a genus over 117 years
Kelsey is very happy to have published her article on flowering and fruiting phenology across the entire genus of Leavenworthia, a taxon with some very highly-endemic species! Moreover, her research has been highlighted by the American Journal of Botany, and featured in a mini-documentary and a press release by Washington University in Saint Louis! To …

Adaptive capacity of small mammals of western North America
Climate change vulnerability assessments have to-date focused primarily on exposure and sensitivity, with adaptive capacity relatively overlooked. In a new paper, an army of mammalogists (and Adam) completed an assessment of the adaptive capacity of several iconic mammals of western North America. Of note, the American pika (Ochotona princeps) has reduced adaptive capacity at the …

Biosphere 2 Biogeography!
This past week, past lab member Lauren and lab lead Adam attended the NSF-funded B2B Workshop at Biosphere 2, in Arizona! Intellectual stimulation and plans for research were had by all.
How should we model rare species’ niches and distributions?
Constructing species distribution models (SDMs) and ecological niche models (ENMs) for very rare species is a very hard challenge–and these are the species for which knowing their distributions and niches would help the most! Recently, Kelley Erickson and I completed an assessment of state-of-the-art methods for modeling rare species in community contexts. In this analysis, …

Matthew Austin’s phenology work featured in multiple news outlets, including USA Today!
Matt’s findings that climate change has induced not only a change in phenology but also a change in reproductive strategy from more to less selfing in the common blue violet, Viola sororia, has been featured by not only USA Today, but also St. Louis’s FOX2 TV and Washington University in Saint Louis’s Climate Change Program! …

Using imprecisely located presences in SDMs
We’ve developed a new, simple, common-sensical method for using imprecisely georeferenced occurrence data in species distribution modeling and other biogeographic analyses! Collectively, imprecise records reflect thousands of years of person-work in collection, curation, and digitization, and yet they are routinely discarded by biogeographers before analysis because of the fear that their error will propagate through …

enmSdmX on CRAN
I’m pleased as punch to announce that enmSdmX, a set of tools in R for implementing species distribution models (SDMs) and ecological niche models (ENMs), is now available on CRAN! The package includes functions found (nearly?) nowhere else for bias correction, spatial cross-validation, model evaluation, raster interpolation, biotic “velocity” (speed and direction of movement of …

Goodbye (for now) to our summer REUs!
We have been honored to serve as the summer home for three wonderful undergraduates in the Garden’s Research Experience for Undergraduates program! Marina, Catherine, and Evelyn explored illegal trade in vulnerable plants, the role of phenology in invasions, and how bees respond to urban environments, respectively. Thank you to all of you an engaging experience, …

Climate change alters plant mating systems
Matthew Austin‘s new open access paper in the American Journal of Botany on how climate has affected plant mating systems is making waves! Using herbarium specimens, Matt found that over the last 100 years, the rate of cleistogamy (asexual flowering) has decreased among Viola sororia, the common blue violet. This change was predicted by increases …
