Impacts of climate change on flowering phenology and production in alpine plants: The importance of end of flowering

, 2020
Changes in the seasonal timing of plant flowering are hypothesized to alter the number of flowers plants produce, which contributes to reproductive success.

Higher‐latitude spring‐flowering herbs advance their phenology more than trees with warming temperatures

Journal of Ecology, 2022
The phenologies of co‐occurring trees and spring‐blooming understory herbs in northeastern North American hardwood forests appear to be regulated by different environmental drivers – air temperature and soil temperature/snowpack, respectively ...

Phylogenetic Patterns among Tropical Flowering Phenologies

The Journal of Ecology, 1995
1 The ability of phylogenetic, water stress and 'shared-pollinator' hypotheses to explain flowering times was tested for the flora of Barro Colorado Island, Panama. Both quantitative (217 species) and qualitative (1173 species) flowering data were used.

A phenological mid-domain effect in flowering diversity

Oecologia, 2004
In this paper, we test the mid-domain hypothesis as an explanation for observed patterns of flowering diversity in two sub-alpine communities of insect-pollinated plants. Observed species richness patterns showed an early-season increase in richness, a mid-season peak, and a late-season decrease. We show that a "mid-domain" null model can qualitatively

Phenology of Entomophilous Flowers

Ecology, 1924
The statements made here are based upon observations, from i884 to 19I3, of 470 indigenous and 54 introduced entomophilous flowers. Twentythree more native and seven introduced species, with an average of five days, are excluded as fragmentary. The time of each flower includes early dates for early seasons and late dates for late seasons, and is ...

Heteroblasty and the Evolution of Flowering Phenologies

International Journal of Plant Sciences, 1999
Flowering phenologies have rarely been examined from a developmental perspective. The production of a flower or inflorescence, however, is an integral part of the ontogeny and architecture of an organism. As a result, basic features of plant developmental morphology have the potential to define options for variation in phenology and to determine, in ...

Long‐term trends in global flowering phenology

New Phytologist
Summary Flowering phenology is an indicator of the impact of climate change on natural systems. Anthropogenic climate change has progressed over more than two centuries, but ecological studies are mostly short in comparison. Here we harness the large‐scale digitization of herbaria specimens to investigate temporal trends in flowering phenology at a ...

Context-dependent conflicting selection on flowering phenology

Proceedings of the Royal Society B: Biological Sciences
Climate change will affect precipitation and water availability in natural plant populations, potentially influencing phenology, fitness and natural selection. To examine how water availability affects non-pollinator- and pollinator-mediated selection on flowering phenology in Primula tibetica

Year clustering analysis for modelling olive flowering phenology

International Journal of Biometeorology, 2012
It is now widely accepted that weather conditions occurring several months prior to the onset of flowering have a major influence on various aspects of olive reproductive phenology, including flowering intensity. Given the variable characteristics of the Mediterranean climate, we analyse its influence on the registered variations in olive flowering ...

Growth controls over flowering phenology response to climate change in three temperate steppes along a precipitation gradient

Agricultural and Forest Meteorology, 2019
Our understanding of how simultaneous climate warming and changing precipitation influence plant phenology in grasslands is still limited. As part of a field transplant experiment, this study was conducted to explore the flowering phenology of the ...
