A Phylogeny of the Hubbardochloinae Including Tetrachaete (Poaceae: Chloridoideae: Cynodonteae)
Peterson, P.M., K. Romaschenko, and Y. Herrera Arrieta. 2020. A phylogeny of the Hubbardochloinae including Tetrachaete (Poaceae: Chloridoideae: Cynodonteae). Phytoneuron 2020-81: 1–13. Published 18 November 2020. ISSN 2153 733 A PHYLOGENY OF THE HUBBARDOCHLOINAE INCLUDING TETRACHAETE (CYNODONTEAE: CHLORIDOIDEAE: POACEAE) PAUL M. PETERSON AND KONSTANTIN ROMASCHENKO Department of Botany National Museum of Natural History Smithsonian Institution Washington, D.C. 20013-7012 [email protected]; [email protected] YOLANDA HERRERA ARRIETA Instituto Politécnico Nacional CIIDIR Unidad Durango-COFAA Durango, C.P. 34220, México [email protected] ABSTRACT The phylogeny of subtribe Hubbardochloinae is revisited, here with the inclusion of the monotypic genus Tetrachaete, based on a molecular DNA analysis using ndhA intron, rpl32-trnL, rps16 intron, rps16- trnK, and ITS markers. Tetrachaete elionuroides is aligned within the Hubbardochloinae and is sister to Dignathia. The biogeography of the Hubbardochloinae is discussed, its origin likely in Africa or temperate Asia. In a previous molecular DNA phylogeny (Peterson et al. 2016), the subtribe Hubbardochloinae Auquier [Bewsia Gooss., Dignathia Stapf, Gymnopogon P. Beauv., Hubbardochloa Auquier, Leptocarydion Hochst. ex Stapf, Leptothrium Kunth, and Lophacme Stapf] was found in a clade with moderate support (BS = 75, PP = 1.00) sister to the Farragininae P.M. Peterson et al. In the present study, Tetrachaete elionuroides Chiov. is included in a phylogenetic analysis (using ndhA intron, rpl32- trnL, rps16 intron, rps16-trnK, and ITS DNA markers) in order to test its relationships within the Cynodonteae with heavy sampling of species in the supersubtribe Gouiniodinae P.M.

NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms. Contributions go to the Natural Heritage & Endangered Species Fund, which provides a portion of the operating budget for the Natural Heritage & Endangered Species Program.

Tchounwou Received: 23 June 2017; Accepted: 9 September 2017; Published: 12 September 2017 Abstract: Trauma is a transgenerational process that overwhelms the community and the ability of family members to cope with life stressors. An anthropologist trained in ethnographic methods observed three focus groups from a non-profit agency providing trauma and mental health services to Asian Americans living in the San Francisco Bay Area of United States. Supplemental information also was collected from staff interviews and notes. Many of the clients were immigrants, refugees, or adult children of these groups. This report consisted of authentic observations and rich qualitative information to characterize the impact of trauma on refugees and immigrants. Observations suggest that collective trauma, direct or indirect, can impede the success and survivability of a population, even after many generations.

We conducted a herbarium-based study and found that Triodia 17 reproduction is driven by precipitation over 12 months, and that high-yield 18 years corresponded to years of high fire likelihood. -
Exploring Spinifex Biomass for Renewable Materials Building Blocks
Exploring Spinifex Biomass for Renewable Materials Building Blocks Nasim Amiralian A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2014 Australian Institute for Bioengineering and Nanotechnology i Abstract Triodia pungens is one of the 69 species of an Australian native arid grass spinifex which covers approximately 27 % (2.1 million km2) of the Australian landmass. The use of fibrous and resinous components of spinifex has been well documented in traditional indigenous Australian culture for thousands of years. In this thesis the utility of both the cellulosic and resinous components of this abundant biomass for modern applications, and a potential economy for our Aboriginal collaborators, were explored. One part of this study was focused on the optimisation of a resin extraction process using solvent, and the subsequent evaluation, via a field trial, of the potential use and efficacy of the resin as a termiticide. Termiticidal performance was evaluated by re-dissolving the extracted resin in acetone and coating on pine timber blocks. The resin-coated and control blocks (uncoated timber) were then exposed to a colony of Mastotermes darwiniensis termites, which are the most primitive active and destructive species in subterranean areas, at a trial site in northeast Australia, for six months. The results clearly showed that spinifex resin effectively protected the timber from termite attack, while the uncoated control samples were extensively damaged. By demonstrating an enhanced termite resistance, it is shown that plant resins that are produced by arid/semi-arid grasses could be potentially used as treatments to prevent termite attack. -
