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, Год журнала: 2021, Номер 108(11), С. 2112 - 2126

Опубликована: Ноя. 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, Год журнала: 2025, Номер 31(3)

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, Год журнала: 2023, Номер 12

Опубликована: Июнь 5, 2023

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.

Botanic Garden Tourism, Social Value, Health, and Well-Being

Journal of Zoological and Botanical Gardens, Год журнала: 2024, Номер 5(2), С. 187 - 199

Опубликована: Апрель 28, 2024

Many botanic gardens are flourishing, and many others can learn from those leading the way; at same time, all form new allegiances informed by service research. We developed this paper to plant seeds for different stakeholders interested in putting a spotlight on garden tourism opportunities. It is response call action across sector greater public engagement, challenge awareness disparity, ensure vitality viability of sector. Our commentary considers positive, transformative making, marketing, management, development. recommend holistic, integrated services via ecosystemic thinking collaborative partnerships with non-traditional design sustainable ecosystems. envisaged that research will spur more responsible, ethical, moral enterprise opportunities drive change meeting development goals good plants, people, planet.

Societal Impact Statement Long‐term phenology data is crucial to elucidate the effects of climate change on plants, but such efforts are lacking in tropics. Historical records at Singapore Botanic Gardens and ongoing phenological monitoring have allowed us study leafing behaviour its association with changing rainfall patterns over nine decades equatorial Singapore. We found that trees our tropical site changed between 1927 2022. This was made possible by assiduous past present record‐keeping, demonstrates potential botanical gardens as sentinels environmental change, which especially important Summary Understanding impacts a requires long‐term rare took advantage availability historical weather ask whether has an exceptionally long period about decades, these changes associated supposedly aseasonal Records leaf flush intervals from 1939 were compared against calculated present‐day conducted since 2016.

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. However, use multi‐year has been thoroughly assessed. paper first reviews projects conducted institutions over three continuous years, that fewer than 1% botanic arboreta globally engage research. There is notable lack diversity, with 3% angiosperm 35% gymnosperm families represented. Monitoring efforts mainly focus phenology pathology, limited attention other subjects like traits. Moreover, no have linked impacts plants urban green space research, despite locations many gardens, structured guidelines exist establishing programmes.

Digital repeat photography is currently applied mainly in geophysical studies of ecosystems. However, its role as a tool that can be utilized conventional phenology, tracking plant's seasonal developmental cycle, growing. This study's main goal was to develop an easy-to-reproduce, single-camera-based novel approach determine the flowering phases 12 woody plants various deciduous species. Field observations served binary class calibration datasets (flowering and non-flowering stages). All image RGB parameters, designated for each plant separately, were used features models' parametrization. The training data subjected transformations achieve best classifications using weighted k-nearest neighbors algorithm. developed models enabled at 0, 1, 2, 3, 5 onset day shift (absolute values) 2 plants, respectively. For 9 presented method duration estimation, which valuable yet rarely parameter phenological studies. We found suitable despite their petal color flower size, until there considerable change crown during stage.
