Earlier flowering did not alter pollen limitation in an early flowering shrub under short-term experimental warming

open access: yesScientific Reports, 2017
In animal pollinated plants, phenological shifts caused by climate change may have important ecological consequences. However, no empirical evidence exists at present on the consequences that flowering phenology shifts have on the strength of pollen ...

Large-effect flowering time mutations reveal conditionally adaptive paths through fitness landscapes in Arabidopsis thaliana. [PDF]

open access: yes, 2019
Contrary to previous assumptions that most mutations are deleterious, there is increasing evidence for persistence of large-effect mutations in natural populations.

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora [PDF]

open access: yes, 2011
Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites,

The sleeping giant needs coffee: Overlooked areas for integrating plant ecophysiology and evolutionary biology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Interpretations of evolutionary outcomes are limited without incorporation of physiological ecology, and ecophysiological interpretations would benefit from incorporating evolutionary perspectives. Although there has been a rise of studies in the last 20 years between these fields, evolutionary studies that incorporate plant physiology have ...

PHENOLOGY OF FLOWERING IN CULTIVATED HELICONIA CHARTACEA [PDF]

open access: yesHortScience, 1990
Although in florescences of H. chartacea `Sexy Pink' can be harvested year'round in Hawaii, flowering is heaviest during the summer while demand is higher during winter months. The research was directed at identifying influences affecting the timing and rate of flower development, Dissection of apices of pseudostems which began development during June ...

Animal‐mediated seed dispersal: A review of study methods

open access: yesApplications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Reproductive phenology and its drivers in a tropical rainforest national park in China: Implications for Hainan gibbon (Nomascus hainanus) conservation

open access: yesGlobal Ecology and Conservation, 2020
Reproductive plant phenology, such as the seasonal timing of flowering or fruiting, influences many aspects of tropical forest communities, but there are few studies examining potential drivers of phenological patterns, especially in south China.

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.
