Published: June 28, 2022

Phenology has emerged as key indicator of the biological impacts climate change, yet role functional traits constraining variation in herbaceous species' phenology received little attention. Botanical gardens are ideal places which to investigate large numbers species growing under common conditions. We ask whether interspecific plant is influenced by differences traits. recorded onset, end, duration and intensity initial growth, leafing out, leaf senescence, flowering fruiting for 212 across five botanical Germany. measured traits, including height, absolute specific area, dry matter content, carbon nitrogen content seed mass accounted relatedness. Closely related showed greater similarities timing phenological events than expected chance, but had a high degree explanatory power, pointing paramount importance life-history strategies. Taller plants later flowered, fruited underwent senescence later. Large-leaved shorter durations. Taller, large-leaved differ their more competitive smaller, small-leaved species. assume warming will change communities' hierarchies with consequences biodiversity.

Macrophenology: insights into the broad‐scale patterns, drivers, and consequences of phenology

American Journal of Botany, Journal Year: 2021, Volume and Issue: 108(11), P. 2112 - 2126

Published: Nov. 1, 2021

Abstract Plant phenology research has surged in recent decades, part due to interest phenological sensitivity climate change and the vital role plays ecology. Many local‐scale studies have generated important findings regarding physiology, responses, risks associated with shifts plant phenology. By comparison, our understanding of regional‐ global‐scale been largely limited remote sensing green‐up without ability differentiate among species. However, a new generation analytical tools data sources—including enhanced products, digitized herbarium specimen data, public participation science—now permits investigating patterns drivers across extensive taxonomic, temporal, spatial scales, an emerging field that we call macrophenology. Recent highlighted how affects dynamics at broad including species interactions ranges, carbon fluxes, climate. At cusp this developing study, review theoretical practical advances four primary areas macrophenology: (1) global phenology, (2) within‐species changes as they mediate species' range limits invasions regional scale, (3) broad‐scale variation leading ecological mismatches, (4) between ecosystem processes. To stimulate future research, describe opportunities for macrophenology address grand challenges each these areas, well recently available sources enhance enable research.

Convergent Strategies for Leaf Traits in Tree Species From Divergent Habitats

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Plant trait expressions and their trade-offs reflect the responses long-term ecological adaptation to environmental gradients. However, how such help plants acclimate a new environment remains poorly understood, which is fundamental preset for plants' survival under global change scenario. By comparing trait-trait relationships of 4403 tree species from different climatic regions variation in 746 that have been transplanted tropical botanical garden several decades, our results reveal convergent but consistent alteration trees common environment. The trends enhance capability buffering impacts climate through allocating more resources growth tolerance. We propose altered may be key mechanisms underlie stability resilience species.

Exploring biocultural diversity in urban ecosystems: an ethnobiological perspective

Ethnobiology and Conservation, Journal Year: 2023, Volume and Issue: 12

Urban ecosystems differ from non-urban ones in the strong and rapid biocultural dynamics generated by interactions between people different cultures, at large spatial temporal scales, very fast rates. This opinion piece explores concept of urban ethnobiology as a critical field research that investigates complex dynamic systems exist environments. We argue humans other life forms are influenced characteristic set social, cultural, political factors linked to environments, such infrastructure development, population density, governance structures. emphasize need for an interdisciplinary approach brings together experts fields study inherent complexity these systems. By examining sociocultural shape way biodiversity is perceived, used, managed, we can gain deeper insights into dimensions socio-cultural areas.

Societal Impact Statement Botanic gardens play a crucial role in addressing global environmental challenges by providing unique setting for long‐term plant studies and engaging the public climate change awareness. Our review highlights underuse of these gardens' living collections monitoring impacts, revealing significant gaps data phylogenetic diversity. The Witness Tree Project at Trinity College Garden will enhance research engagement through open‐access protocols. This initiative not only advances scientific understanding but also fosters community involvement education, promoting collective effort towards mitigating impacts. Summary are ideal settings on responses to change, extensive outreach visitor opportunities.
