Delayed Self-Pollination as the Primary Reproductive Strategy in <i>Cypripedium shanxiense</i> S. C. Chen: Observations From Beijing Songshan National Nature Reserve. [PDF]

Plant Environ Interact
ABSTRACT Studying the pollination biological characteristics of the rare and endangered plant Cypripedium shanxiense S. C. Chen will provide a scientific basis for formulating conservation strategies for the species. This study investigates the flowering phenology, pollination insects, and the process of pollination and fruiting of C. shanxiense at the

Mating strategies of Vitex negundo L. var. heterophylla (Franch.) Rehder (Lamiaceae): A mixed mating system with inbreeding depression. [PDF]

Ecol Evol
We evaluated reproductive success through artificial pollination to explore the reproductive characteristics of Vitex negundo var. heterophylla for the first time. From the results of fruit set, there is a mixed mating system dominated by outcrossing in V. negundo var.

The impacts of flowering phenology on the reproductive success of the narrow endemic Nouelia insignis Franch. (Asteraceae). [PDF]

Ecol Evol, 2021
Natural population of Nouelia insignis exhibited high flowering synchrony with relatively stable flowering duration, and the flowering time fluctuated greatly between years depending on the rainfall 5 months before flowering. The pollination of N. insignis required pollinators, and insect activities might play a very important role in the pollination ...

Towards a better understanding of the relationships between pollinators, human well‐being, and medicine plants in the Great Lakes Region of Eastern North America

PLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 842-851, November 2023., 2023
A diversity of values is needed to maximize the effectiveness of conservation planning, including policies and programs. The results of the United Nations Biodiversity Conference (COP 15) in Montreal, Canada, highlight the importance of a shift towards recognizing multiple ways of knowing in ecology and conservation.

Pollination mode and reproductive system of Sanguisorba minor and Sanguisorba officinalis

Plant Species Biology, Volume 38, Issue 4, Page 171-179, July 2023., 2023
Within one plant clade, often species with different pollination modes (e.g., wind and insect pollination) exist. We investigate the pollination and reproductive strategies of Sanguisorba minor and Sanguisorba officinalis and document remarkable differences between the two species.

Beyond pollen:ovule ratios: Evolutionary consequences of pollinator dependence and pollination efficiency for pollen and ovule production in angiosperms

American Journal of Botany, Volume 110, Issue 6, June 2023., 2023
Abstract Premise The relative per‐flower production of ovules and pollen varies broadly with angiosperm mating systems, with outcrossing types commonly producing more pollen grains per ovule than selfing types. The evolutionary causes of this variation are contentious, especially the relevance of pollination risk.

Reproductive biology of the biofuel plant Jatropha curcas in its center of origin [PDF]

PeerJ, 2016
In this work, we studied the main characteristics of flowering, reproductive system and diversity of pollinators for the biofuel plant Jatropha curcas (L.) in a site of tropical southeastern Mexico, within its center of origin. The plants were monoecious

Strong conservatism of floral morphology during the rapid diversification of the genus Helianthemum

American Journal of Botany, Volume 110, Issue 5, May 2023., 2023
Abstract Premise Divergence of floral morphology and breeding systems are often expected to be linked to angiosperm diversification and environmental niche divergence. However, available evidence for such relationships is not generalizable due to different taxonomic, geographical and time scales.

Is there a hybridization barrier between Gentiana lutea color morphs? [PDF]

PeerJ, 2015
In Gentiana lutea two varieties are described: G. lutea var. aurantiaca with orange corolla colors and G. lutea var. lutea with yellow corolla colors. Both color varieties co-occur in NW Spain, and pollinators select flower color in this species.

The best of two worlds: ecology and evolution of ambophilous plants

Biological Reviews, Volume 98, Issue 2, Page 391-420, April 2023., 2023
ABSTRACT Ambophily, the mixed mode of wind and insect pollination is still poorly understood, even though it has been known to science for over 130 years. While its presence has been repeatedly inferred, experimental data remain regrettably rare. No specific suite of morphological or ecological characteristics has yet been identified for ambophilous ...
