  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • Phenotypic Landscape Inference Reveals Multiple Evolutionary Paths to C4 Photosynthesis
    RESEARCH ARTICLE elife.elifesciences.org Phenotypic landscape inference reveals multiple evolutionary paths to C4 photosynthesis Ben P Williams1†, Iain G Johnston2†, Sarah Covshoff1, Julian M Hibberd1* 1Department of Plant Sciences, University of Cambridge, Cambridge, United Kingdom; 2Department of Mathematics, Imperial College London, London, United Kingdom Abstract C4 photosynthesis has independently evolved from the ancestral C3 pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear. Here we show that the polyphyletic appearance of C4 photosynthesis is associated with diverse and flexible evolutionary paths that group into four major trajectories. We conducted a meta-analysis of 18 lineages containing species that use C3, C4, or intermediate C3–C4 forms of photosynthesis to parameterise a 16-dimensional phenotypic landscape. We then developed and experimentally verified a novel Bayesian approach based on a hidden Markov model that predicts how the C4 phenotype evolved. The alternative evolutionary histories underlying the appearance of C4 photosynthesis were determined by ancestral lineage and initial phenotypic alterations unrelated to photosynthesis. We conclude that the order of C4 trait acquisition is flexible and driven by non-photosynthetic drivers. This flexibility will have facilitated the convergent evolution of this complex trait. DOI: 10.7554/eLife.00961.001 Introduction *For correspondence: Julian. The convergent evolution of complex traits is surprisingly common, with examples including camera- [email protected] like eyes of cephalopods, vertebrates, and cnidaria (Kozmik et al., 2008), mimicry in invertebrates and †These authors contributed vertebrates (Santos et al., 2003; Wilson et al., 2012) and the different photosynthetic machineries of equally to this work plants (Sage et al., 2011a).

  • Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
    UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation.

HERBST (Hawaii Biological Survey, Bishop Museum, 1525 Bernice St., Honolulu, HI 96817–2704, USA; email: [email protected]) These previously unpublished Hawaiian plant records report 16 new state (including nat- uralized) records, 25 new island records, and 14 nomenclatural and taxonomic changes that affect the flora of Hawai‘i. The ongoing incorporation of the state Endangered Species Program herbarium developed by the Hawaii Department of Land and Natural Resources, Division of Forestry and Wildlife (DLNR/DoFaW), into the BISH herbarium has brought to light a number of voucher specimens from the 1970s and 1980s that are first records for the state or for particular islands. These records supplement information published in Wagner et al. (1990, 1999) and in the Records of the Hawaii Biological Survey for 1994 (Evenhuis & Miller, 1995), 1995 (Evenhuis & Miller, 1996), 1996 (Evenhuis & Miller, 1997), 1997 (Evenhuis & Miller, 1998), 1998 (Evenhuis & Eldredge, 1999), and 1999 (Evenhuis & Eldredge, 2000).

  • Biodiversity in Forests of the Ancient Maya Lowlands and Genetic
    Biodiversity in Forests of the Ancient Maya Lowlands and Genetic Variation in a Dominant Tree, Manilkara zapota (Sapotaceae): Ecological and Anthropogenic Implications by Kim M. Thompson B.A. Thomas More College M.Ed. University of Cincinnati A Dissertation submitted to the University of Cincinnati, Department of Biological Sciences McMicken College of Arts and Sciences for the degree of Doctor of Philosophy October 25, 2013 Committee Chair: David L. Lentz ABSTRACT The overall goal of this study was to determine if there are associations between silviculture practices of the ancient Maya and the biodiversity of the modern forest. This was accomplished by conducting paleoethnobotanical, ecological and genetic investigations at reforested but historically urbanized ancient Maya ceremonial centers. The first part of our investigation was conducted at Tikal National Park, where we surveyed the tree community of the modern forest and recovered preserved plant remains from ancient Maya archaeological contexts. The second set of investigations focused on genetic variation and structure in Manilkara zapota (L.) P. Royen, one of the dominant trees in both the modern forest and the paleoethnobotanical remains at Tikal. We hypothesized that the dominant trees at Tikal would be positively correlated with the most abundant ancient plant remains recovered from the site and that these trees would have higher economic value for contemporary Maya cultures than trees that were not dominant. We identified 124 species of trees and vines in 43 families. Moderate levels of evenness (J=0.69-0.80) were observed among tree species with shared levels of dominance (1-D=0.94). From the paleoethnobotanical remains, we identified a total of 77 morphospecies of woods representing at least 31 plant families with 38 identified to the species level.
