Abstract
Imagine going to a garden store and buying every kind of vegetable seed packet for sale. Sow them all in a patch of bare ground, and then try to predict which particular species will be harvestable at the end of the season. Even the best ecological science is stymied by this simple challenge. An open problem is predicting or controlling the dynamics of communities, whether they are vegetable gardens or tropical forests.
The goal of this work is to develop biodiversity theory that can link across scales from individuals to communities to ecosystems. A more predictive ecological science could 1) delineate the processes and mechanisms that operate at or across different spatial scales and 2) generate falsifiable predictions for biodiversity dynamics in specific systems over time. To begin to address these aims, I will test two key ideas: first, that organisms' physiology needs to be built in to models of population growth; and second, that the matching between physiology and environment is not necessarily optimal, because of disequilibrium caused by lagged responses of organisms to rapid change. Over the next five years I will expand and test these ideas in a set of long-term study sites spanning the lowland tropics of Malaysia to the high alpine of Colorado.

Planned Impact
The primary beneficiaries of this work will be the international academic ecology community, as detailed under the 'Academic beneficiaries' subsection. Briefly, this work will provide a set of conceptual ideas and immediately usable models / software tools that will enable more robust thinking in community ecology.
The predictive modeling approaches pioneered by this proposal will provide benefits for land-management agencies and other groups interested in predicting or managing species' distributions under changing climates or external disturbance. Extrapolating species response to novel conditions remains an ongoing but highly practical challenge in ecology.
The project will also provide training and educational benefits for several students both in and out of the UK. The fieldwork in the United States, Malaysia, Ghana, and Peru will involve several local research assistants who will likely be masters' students from their respective countries. I will be able to provide additional training and international contacts for these students. Within the UK, I will supervise several students engaged in laboratory work to analyze samples collected for these projects. This work will provide valuable research experience that will increase these students' competitiveness for future jobs or research careers.
Lastly, the project will impact the public through engagement with this research. I will share photographs and short essays about my research through international photo competitions and my outreach blog (bblonder.wordpress.com). I have previously won several competitions and had images featured in journals such as BMC Ecology and newspapers such as The Guardian. My blog receives 20-50 visitors per day, primarily from Europe but also from a range of other countries.

Description | I have successfully completed the major data objectives relevant to this grant, i.e. establishment and monitoring of long-term plant demography plots in the Colorado alpine zone, as well as intensive collection of functional traits in that Colorado site and in a disturbance gradient in Malaysian Borneo (datasets D1 and D2 of the Case for Support). These datasets have been analyzed answer Q3 of the proposal. I am developing theory for disequilibrium dynamics. I have published in American Naturalist a key paper sketching methods for inferring how invasions may occur in plant communities via 'holes' in niche or trait hypervolumes, and have also published another paper relevant to the theory of how traits mediate community assembly, published at Ecology, and another paper focused on how community composition (in terms of traits or niches) can track environmental change, or fail to, which is now published in Ecology Letters. Three other papers further develop concepts for community assembly based on niches. These projects address Q2 and Q4 of the proposal. Ongoing work I am leading is also using a range of empirical datasets to test some of these ideas, including plant ecophysiology data from Peru and Borneo, plant pollen assemblage timeseries from North America, contemporary plant community composition time series from North America, bird morphology data at global scale, and global-scale plant composition and paleoclimate time series data. These studies are ongoing and will address a range of questions relevant to how quickly communities can respond to climate change, how predictable their responses are, and whether organisms' traits are useful predictors of these responses. Three papers addressing Q4 have now been published. Separately I have published theory for leaf energy balance (addressing Q5) with an American collaborator, and another still in review. Other trait and microclimate data (also relevant to Q5) has now been collected from Borneo and are now published. This work has also supported research experiences for several students, including three co-supervised masters students (two of whom received a distinction last year for their finished theses), four summer undergraduate research students (both from under-represented Native American backgrounds). The overall impact in the three years of this grant is to have built much of the key theoretical apparatus to succeed with the grant's major objectives, and to have published several empirical studies testing theoretical predictions or demonstrating the utility of the grant's core ideas. Most of the key theory papers are out, and the major empirical datasets are now published. Additional projects relevant to the grant are largely completed and are in review at journals. I feel that the project's goals will be realized once these papers have been published. |
Exploitation Route | The theory and concepts I am developing are likely to shape the way in which modeling of future climate change responses and species invasions will be carried out. These concepts/tools are implemented in freely available R software and can be easily made relevant. |

Description | The pathways to impact funding is supporting at least 300 hours of environmental education teaching in the United States by a graduate student, and has also supported the development of an extensive set of inquiry-based environmental education resources to be shared and implemented in the US and UK. These materials have now been piloted with a group of 20-30 geography teacher trainees in the UK, 30 teachers in the USA, and are also being implemented this year in a series of two one-week programs reaching approximately 100 US-based students. Further curriculum development has supported the production of a guide to best practices in mentoring and inquiry-based teaching that will shortly be made publicly available, advertised to teachers, and presented at international meetings. As of 2023 we had a book accepted for publication by Routledge on place-based science education, the majority of whose content was developed by me during this award. This book is anticipated to have a large impact on secondary school education. |

Title | Data from: Linking microenvironment modification to species interactions and demography in an alpine plant community |
Description | Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co-occurring alpine plants, we (1) determined the extent of species-specific microclimate modification by comparing temperature and soil moisture between vegetated and non-vegetated microsites for several focal species. We (2) determined how vital rates (survival, growth, fecundity) of all species varied in response to aboveground and belowground vegetative overlap with inter- and intraspecific neighbors as proxies for microenvironment modification. For (1), surface temperatures were buffered (lower maximums and higher minimums) and soil moisture was higher below the canopies of most species compared to non-vegetated areas. For (2), vegetative overlap predicted the most vital rates, although the effect varied depending on whether aboveground or belowground overlap was considered. Vital rate response to microenvironment-modification proxies (vegetative overlap) was also frequently context-dependent with respect to plant size and macroclimate. Microenvironment modification and spatial overlapping of individuals are key drivers of demography and species interactions in this alpine community. |
