Schiedea waiahuluensis (Caryophyllaceae), an enigmatic new species from Kaua'i, Hawaiian Islands and the first species discovered by a drone collection system

Autor: Warren L. Wagner, Stephen G. Weller, Ann K. Sakai, Ben Nyberg, Kenneth R. Wood

Publikováno v: PhytoKeys, Vol 247, Iss , Pp 111-121 (2024)

During a survey by the National Tropical Botanical Garden drone team, an enigmatic Schiedea was observed in December 2021on steep, rocky cliff faces of the Waiahulu Valley in the Waimea Canyon of Kaua'i. Subsequently, another survey was conducted in

Schiedea haakoaensis, a new facultatively autogamous species of Schiedea sect. Mononeura (Caryophyllaceae) from the Hawaiian Islands

Autor: Warren L. Wagner, Stephen G. Weller, Ann K. Sakai, Tom DeMent, Josh VanDeMark

Publikováno v: PhytoKeys, Vol 210, Iss , Pp 135-141 (2022)

In 2016 during a survey for potential fencing of the Ha‘akoa unit on windward Mauna Kea, Hawai‘i Island (Hawaiian Islands) a single plant of the genus Schiedea was discovered. No species of the genus had ever been known to occur in this area, and

Floral Scent Composition and Fine-Scale Timing in Two Moth-Pollinated Hawaiian Schiedea (Caryophyllaceae)

Autor: John M. Powers, Roger Seco, Celia L. Faiola, Ann K. Sakai, Stephen G. Weller, Diane R. Campbell, Alex Guenther

Publikováno v: Frontiers in Plant Science, Vol 11 (2020)

Floral scent often intensifies during periods of pollinator activity, but the degree of this synchrony may vary among scent compounds depending on their function. Related plant species with the same pollinator may exhibit similar timing and compositi

Genetic potential for changes in breeding systems: Predicted and observed trait changes during artificial selection for male and female allocation in a gynodioecious species

Publikováno v: American journal of botany, vol 109, iss 11

PremiseEvolution of separate sexes from hermaphroditism often proceeds through gynodioecy, but genetic constraints on this process are poorly understood. Genetic (co-)variances and between-sex genetic correlations were used to predict evolutionary re

What determines the evolutionary trajectories of wild plant species? Approaches to the study of quantitative fitness-related traits

Autor: Susan J. Mazer, Ann K. Sakai, Stephen G. Weller, Eugenio Larios

Publikováno v: American journal of botanyREFERENCES. 109(11)

Wild plant species provide excellent examples of qualitative traits that evolve in response to environmental challenges (e.g., flower color, heavy metal tolerance, cyanogenesis, and male sterility). In addition to such discrete characters, a dazzling

Variation in floral volatiles across time, sexes, and populations of wind-pollinated Schiedea globosa

Autor: John M. Powers, Ann K. Sakai, Stephen G. Weller, Diane R. Campbell

Publikováno v: American journal of botanyREFERENCES. 109(2)

Floral scent is a key aspect of plant reproduction, but its intraspecific variation at multiple scales is poorly understood. Sexual dimorphism and temporal regulation of scent can be shaped by evolution, and interpopulation variation may be a bridge

The effects of introduced ungulates on native and alien plant species in an island ecosystem: Implications for change in a diverse mesic forest in the Hawaiian Islands

Autor: Wendy Kishida, David H. Lorence, Stephen G. Weller, Ann K. Sakai, Ken Wood, Michelle Clark, Natalia Tangalin, Timothy Flynn

Publikováno v: Forest Ecology and Management. 409:518-526

In island ecosystems, where endemic species have long been viewed as competitively inferior and more susceptible to herbivory relative to continental species, the impacts of invasive species may be especially pronounced. The sensitivity of island spe

The intersection of basic research and conservation: a 30-year study of the Critically Endangered Schiedea adamantis (Caryophyllaceae) on Lē‘ahi (Diamond Head Crater), Hawai‘i

Autor: Marie M. Bruegmann, Susan Ching Harbin, Greg Mansker, Weigang Yang, Ann K. Sakai, Talia Portner, Stephen G. Weller

Publikováno v: Oryx. 52:479-488

We report on how a long-term study of the reproductive biology of the Critically Endangered Schiedea adamantis (Caryophyllaceae), one of Hawai‘i's rarest plant species, was leveraged for conservation purposes. Our major goals were to provide seeds

We present a Bayesian method for characterizing the mating system of populations reproducing through a mixture of self-fertilization and random outcrossing. Our method uses patterns of genetic variation across the genome as a basis for inference abou
