| Abstract |
- Changes in phenology induced by climate change occur
across the globe with important implications for ecosystem functioning
and services, species performance and trophic interactions. Much of the
work on phenology, especially leaf out and flowering, has been conducted
on woody plant species. Less is known about the responses in phenology
of herbaceous species induced by global change even though they
represent a large and important part of biodiversity worldwide. A
globally co‐ordinated research effort is needed in order to understand
the drivers and implications of such changes and to predict effects of
global change on plant species phenology and related ecosystem
processes.
- Here, we present the rationale of the PhenObs
initiative ‐ botanical gardens as a global phenological observation
network. The initiative aims to collect data on plant phenology in
botanical gardens which will be used alongside information on plant
traits and site conditions to answer questions related to the
consequences of global change:
A.What is the variation in plant phenology in
herbaceous species across the growing season and in response to changes
in climate?
B.How can plant phenology be predicted from species’
trait composition, provenance, position and extent of the distribution
range and species’ phylogeny?
C.What are the implications of this variation with
respect to species performance and assembly, biotic interactions (e.g.
plant‐pollinator interactions) as well as ecosystem processes and
services under changing land‐use and climate? - Here, we lay out the development of a straightforward
protocol that is appropriate for monitoring phenology across a vast
diversity of growth forms of herbaceous species from various habitats
and geographic regions.
- In order to focus on a key number of stages necessary to
capture all aspects of plant species phenology, we analysed
associations between 14 phenological stages. These data were derived
from a two‐year study on 199 species in four German botanical gardens.
- Based on the relationships of the phenological stages,
we propose to monitor three vegetative stages (“initial growth”, “leaves
unfolding” and “senescence”) and two reproductive stages (“flowers
open” and “ripe fruits”) to fully capture herbaceous species phenology.
