Variation in plant traits and phylogenetic structure associated with native and nonnative species in an industrialized flora

Autor: Samantha J. Worthy, Travis D. Marsico, Rima D. Lucardi, Lauren E. Whitehurst, Kevin S. Burgess

Publikováno v: NeoBiota, Vol 77, Iss , Pp 101-123 (2022)

Industrialized sites are hotspots for nonnative species because of continuous anthropogenic disturbance and nonnative propagule rain resulting from hitchhikers exchanged through global trade. Investigating plant traits and the phylogenetic structure

Comparative transcriptomics of tropical woody plants supports fast and furious strategy along the leaf economics spectrum in lianas

Autor: U. Uzay Sezen, Samantha J. Worthy, Maria N. Umaña, Stuart J. Davies, Sean M. McMahon, Nathan G. Swenson

Publikováno v: Biology Open, Vol 11, Iss 7 (2022)

Lianas, climbing woody plants, influence the structure and function of tropical forests. Climbing traits have evolved multiple times, including ancestral groups such as gymnosperms and pteridophytes, but the genetic basis of the liana strategy is lar

Site‐specific impacts of a major hurricane on alpha and beta diversity in tropical forest seedling communities

Autor: Samantha J. Worthy, Vanessa E. Rubio, Kirstin Staiger, Boris Ngouajio, Jie Yang, Nathan G. Swenson

Publikováno v: Ecosphere, Vol 12, Iss 7, Pp n/a-n/a (2021)

Abstract Large scale disturbances are known to impact the alpha and beta diversity of communities. However, whether these disturbances increase or decrease diversity is often debated. The goal of this study was to quantify how the diversity of the se

Functional perspectives on tropical tree demography and forest dynamics

Autor: Samantha J. Worthy, Nathan G. Swenson

Publikováno v: Ecological Processes, Vol 8, Iss 1, Pp 1-11 (2019)

Abstract Disentangling the processes that drive population, community and whole forest structure and dynamics is a challenge. It becomes a grand challenge in the tropics where there are a large number of species, small population sizes, less research

Distribution and Community Assembly of Trees Along an Andean Elevational Gradient

Autor: Samantha J. Worthy, Rosa A. Jiménez Paz, Álvaro J. Pérez, Alex Reynolds, Jennifer Cruse-Sanders, Renato Valencia, John A. Barone, Kevin S. Burgess

Publikováno v: Plants, Vol 8, Iss 9, p 326 (2019)

Highlighting patterns of distribution and assembly of plants involves the use of community phylogenetic analyses and complementary traditional taxonomic metrics. However, these patterns are often unknown or in dispute, particularly along elevational

Germination responses to experimental rainfall timing identify potential vulnerability to climate change across a clade of California wildflowers

Autor: Samantha J. Worthy, Arquel Miller, Sarah R. Ashlock, Eda Ceviker, Julin N. Maloof, Sharon Y. Strauss, Johanna Schmitt, Jennifer R. Gremer

The timing of germination, driven by seasonal cues, is critical for the life cycle of plants. Variation among species in germination responses can reflect evolutionary processes and adaptation to local climate and can reveal vulnerability to changing

Decomposing intraspecific phenotypic variation: implications for species and functional diversity

Autor: Samantha J. Worthy, María N. Umaña, Caicai Zhang, Luxiang Lin, Min Cao, Nathan G. Swenson

Background and AimsResearchers have a long history of seeking an explanation for and understanding of diversity patterns. High-dimensional trait-based trade-offs have been hypothesized as being important for maintaining species and functional diversi

Phytochemical diversity, endemism and their adaptations to abiotic and biotic pressures in fine roots across a climatic gradient

Autor: Yazhou Zhang, Samantha J. Worthy, Shijia Xu, Yunyun He, xuezhao Wang, Xiaoyang Song, Min Cao, Jie Yang

Phytochemicals are greatly ignored in trait-based ecology. Especially, the adaptations of phytochemicals to abiotic and biotic pressures in the rhizosphere are less understood. Here, we measured the metabolomics of fine roots and their rhizosphere mi

Leaf gene expression trajectories during the growing season are consistent between sites and years in American beech

Autor: U. Uzay Sezen, Jessica E. Shue, Samantha J. Worthy, Stuart J. Davies, Sean M. McMahon, Nathan G. Swenson

Transcriptomics, the quantification of gene expression, provides a versatile tool for ecological monitoring. Here, we show that through genome-guided profiling of transcripts mapping to 33,042 loci, gene expression differences can be discerned among
