| Abstract |
- Understanding the role of functional traits in
shaping plant phenology is crucial for understanding how organisms adapt
to changing environmental conditions. As climate change alters seasonal
timing and disrupts ecological interactions, identifying relationships
between phenology and traits is essential for predicting species'
responses and potential mismatches.
- While vegetative traits such as plant height and leaf
area are often associated with phenological variation, floral traits,
which are closely linked to reproductive success, remain largely
unexplored, despite their potential to significantly influence
phenology. This study aims to understand the relative influence of
floral and vegetative traits on patterns of species-specific
phenological variation.
- We monitored the year-round phenology (initial
growth, leaf out, onset, peak, end and duration of flowering, fruiting
and senescence) of 68 herbaceous perennial plant species in three German
botanical gardens (Halle, Jena, Berlin). We measured four vegetative
traits—plant height, leaf area, specific leaf area (SLA) and leaf dry
matter content (LDMC)—as well as 12 floral traits related to flower
morphology, flower number, nectar and pollen, with all measurements
conducted for each species in each garden at flowering time. As a basis
for the inclusion of floral traits in studies on phenology–trait
relationships, we used these data to analyse underlying trait
correlations and trade-offs between floral and vegetative traits.
- Analysis of boosted regression trees that accounted
for phylogenetic dependence of the species showed that vegetative
traits, especially vegetative height, were most important for explaining
patterns in reproductive and vegetative phenology. Taller plants showed
later initial growth and later flowering and fruiting compared to
smaller plants, and higher LDMC was associated with later senescence.
Floral traits had an additional relative influence on phenological
patterns but were of minor importance overall.
- Synthesis: Our study confirms that vegetative traits
offer a robust explanatory framework for phenology, while also
emphasizing the value of considering both vegetative and floral traits
in understanding these patterns. Our findings offer a basis for
exploring the functional relevance of rarely measured floral traits,
such as pollen traits, within the plant economic spectrum and in
plant–pollinator interaction studies.
