Falcataria Moluccana Molucca Albizia Fabaceae
Falcataria moluccana Molucca albizia Fabaceae Forest Starr, Kim Starr, and Lloyd Loope United States Geological Survey--Biological Resources Division Haleakala Field Station, Maui, Hawai'i January, 2003 OVERVIEW Falcataria moluccana has been widely planted throughout the world for ornament and reforestation. It was first introduced to Hawai'i in 1917 by Joseph Rock (Little and Skolmen 1989). In Hawai'i, F. moluccana has been planted by the hundreds of thousands for ornament and reforestation. Trees are attractive and the wood is useful for a variety of things from furniture making to canoe building. However, trees are spreading from initial plantings to adjacent pastures, forests, and disturbed areas. Because of its widespread distribution throughout the state coupled with its popularity, perhaps the best approach currently would be to control the tree in certain sites where it is not wanted, such as natural areas, pastures, and farmland. Seeds tend to fall nearby and trees do not disperse over a long distance (miles), except when people move the tree to a new area. If this dispersal trend were to change, such as if a vector to spread the trees further arrived or if it was planted again on a grand scale to new areas, the tree may become a bigger problem. TAXONOMY Family: Fabaceae (pea family) (Wagner et al. 1999). Latin name: Falcataria moluccana (Miq.) Barneby and Grimes (Herbarium Pacificum Staff 1998). Synonyms: Paraserianthes falcataria (L.) I. Nielsen (Wagner et al. 1999), Albizia falcataria (L.) Fosberg, A. falcata (L.) Backer (Little and Skolmen 1989). Common names: Molucca albizia (Little and Skolmen 1989). Taxonomic notes: There seems to be a lot of name changing and rearranging that has occurred within this complex. -

(OUV) of the Wet Tropics of Queensland World Heritage Area
Handout 2 Natural Heritage Criteria and the Attributes of Outstanding Universal Value (OUV) of the Wet Tropics of Queensland World Heritage Area The notes that follow were derived by deconstructing the original 1988 nomination document to identify the specific themes and attributes which have been recognised as contributing to the Outstanding Universal Value of the Wet Tropics. The notes also provide brief statements of justification for the specific examples provided in the nomination documentation. Steve Goosem, December 2012 Natural Heritage Criteria: (1) Outstanding examples representing the major stages in the earth’s evolutionary history Values: refers to the surviving taxa that are representative of eight ‘stages’ in the evolutionary history of the earth. Relict species and lineages are the elements of this World Heritage value. Attribute of OUV (a) The Age of the Pteridophytes Significance One of the most significant evolutionary events on this planet was the adaptation in the Palaeozoic Era of plants to life on the land. The earliest known (plant) forms were from the Silurian Period more than 400 million years ago. These were spore-producing plants which reached their greatest development 100 million years later during the Carboniferous Period. This stage of the earth’s evolutionary history, involving the proliferation of club mosses (lycopods) and ferns is commonly described as the Age of the Pteridophytes. The range of primitive relict genera representative of the major and most ancient evolutionary groups of pteridophytes occurring in the Wet Tropics is equalled only in the more extensive New Guinea rainforests that were once continuous with those of the listed area. -
Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al. -
Serianthes Nelsonii Seed Germination and Seedling Behavior Are Minimally Influenced by Chemical and Light Treatment
horticulturae Communication Serianthes nelsonii Seed Germination and Seedling Behavior are Minimally Influenced by Chemical and Light Treatment Thomas E. Marler College of Natural and Applied Sciences, University of Guam, Mangilao, Gu 96923, USA; [email protected]; Tel.: +1-671-735-2100 Received: 20 March 2019; Accepted: 12 April 2019; Published: 16 April 2019 Abstract: The role of seed imbibition and light during germination are not known for the critically endangered Serianthes nelsonii Merr. Scarified seeds were pre-soaked in gibberellic acid (GA3) up to 300 mg/L and nitrate solutions of 3000 mg/L to determine if germination was influenced by these treatments. Scarified and imbibed seeds were incubated in high red:far red and low red:far red light to determine the influence of light quality on germination traits. The GA3 and nitrate treatments did not influence germination percentage or timing, but did increase the height of newly emerged seedlings. Moreover, GA3 extended the longevity of cotyledons and shortened the window of time that seedlings required to resume height growth. These growth responses were not sustained, and all seedlings reached heights of 30 cm at a similar number of weeks. The light treatments did not influence any of the germination response traits. The results indicate that imbibing seeds with chemical solutions and providing light in a range of light quality treatments exerted a minimal influence on S. nelsonii seed germination behaviors. Imbibing seeds with water and germinating in darkness is sufficient for achieving the germination of this endangered tree species. Keywords: endangered species; Guam; imbibition; priming 1. Introduction The seed-to-seedling transition is an important phenological transition and every plant species exhibits a unique suite of requirements for germination and seedling establishment [1–3]. -
Evolution of Endosperm Developmental Patterns Among Basal Flowering Plants

All rights reserved. 1058-5893/2000/16106S-0005$03.00 EVOLUTION OF ENDOSPERM DEVELOPMENTAL PATTERNS AMONG BASAL FLOWERING PLANTS Sandra K. Floyd1 and William E. Friedman Department of Environmental, Population, and Organismic Biology, CB 334, University of Colorado, Boulder, Colorado 80309, U.S.A. A phylogenetically based comparative investigation of endosperm development was undertaken in a sample of 13 basal angiosperm taxa. The specific goals were to (1) provide a full developmental analysis of all aspects of endosperm in each species, (2) compare patterns among taxa to determine phylogenetic character distri- bution, (3) reconstruct the ancestral developmental pattern for angiosperms, and (4) explore scenarios of ontogenetic evolution that occurred during the early radiation of flowering plants. Five taxa, Acorus calamus, Cabomba caroliniana, Ceratophyllum demersum, Drimys winteri, and Platanus racemosa, are described in detail. Data from an additional eight taxa were analyzed and compared with these five. Endosperm ontogeny can be conceived of as a series of stages (characters) during which differential patterns of development occur among taxa (character states). We discovered that differential developmental fate of chalazal and micropylar domains is a common pattern among the endosperms of all basal angiosperm taxa and suggest that this may be a feature of endosperm development in all angiosperms. Differential development of chalazal and micropylar domains in endosperm in basal angiosperms also bears a marked similarity to what occurs in angiosperm embryos. This may have implications for understanding the evolutionary origin of endosperm. Basal angio- sperms also exhibit variable endosperm developmental characters, indicating that significant ontogenetic trans- formation occurred during the early radiation of the clade, although magnoliid taxa exhibit a high degree of conservation in endosperm characters. -

Angiosperms) Julien Massoni1*, Thomas LP Couvreur2,3 and Hervé Sauquet1
Massoni et al. BMC Evolutionary Biology (2015) 15:49 DOI 10.1186/s12862-015-0320-6 RESEARCH ARTICLE Open Access Five major shifts of diversification through the long evolutionary history of Magnoliidae (angiosperms) Julien Massoni1*, Thomas LP Couvreur2,3 and Hervé Sauquet1 Abstract Background: With 10,000 species, Magnoliidae are the largest clade of flowering plants outside monocots and eudicots. Despite an ancient and rich fossil history, the tempo and mode of diversification of Magnoliidae remain poorly known. Using a molecular data set of 12 markers and 220 species (representing >75% of genera in Magnoliidae) and six robust, internal fossil age constraints, we estimate divergence times and significant shifts of diversification across the clade. In addition, we test the sensitivity of magnoliid divergence times to the choice of relaxed clock model and various maximum age constraints for the angiosperms. Results: Compared with previous work, our study tends to push back in time the age of the crown node of Magnoliidae (178.78-126.82 million years, Myr), and of the four orders, Canellales (143.18-125.90 Myr), Piperales (158.11-88.15 Myr), Laurales (165.62-112.05 Myr), and Magnoliales (164.09-114.75 Myr). Although families vary in crown ages, Magnoliidae appear to have diversified into most extant families by the end of the Cretaceous. The strongly imbalanced distribution of extant diversity within Magnoliidae appears to be best explained by models of diversification with 6 to 13 shifts in net diversification rates. Significant increases are inferred within Piperaceae and Annonaceae, while the low species richness of Calycanthaceae, Degeneriaceae, and Himantandraceae appears to be the result of decreases in both speciation and extinction rates. -
Bi-Pinnate Compound Serianthes Nelsonii Leaf-Level Plasticity Magnifies Leaflet-Level Plasticity
biology Communication Bi-Pinnate Compound Serianthes nelsonii Leaf-Level Plasticity Magnifies Leaflet-Level Plasticity Benjamin E. Deloso and Thomas E. Marler * Western Pacific Tropical Research Center, College of Natural and Applied Sciences, University of Guam, UOG Station, Mangilao, GU 96923, USA; [email protected] * Correspondence: [email protected] Received: 18 August 2020; Accepted: 20 September 2020; Published: 13 October 2020 Simple Summary: Trees are not able to move in order to avoid stressful conditions. Therefore, trees have developed elaborate methods for modifying their organs to benefit the tree under prevailing conditions. For low light and high light conditions, most studies have looked at how the leaf blade is modified. We have shown that the entire leaf should be observed for modifications rather than just the leaf blade. Abstract: Numerous leaf traits exhibit developmental plasticity in response to irradiance, an attribute that maximizes performance in the prevailing light. The use of leaflets to represent whole leaf traits of tree species with compound leaves is common in the acclimation literature. These methods ignore the potential for whole leaf plasticity to augment leaflet plasticity. We grew Serianthes nelsonii plants in incident light ranging from 6% to 100% of sunlight and quantified numerous leaflet and leaf traits to determine plasticity index (PI: (maximum-minimum)/maximum)) of each. Leaflet acclimation such as changes in length of palisade mesophyll occurred as expected. However, leaf-level morphometric traits such as rachillae insertion angle also exhibited acclimation potential. The leaf-level plastic behavior enabled acclimation approaches that simple-leaved species do not possess. We illuminate the need to look at the entire leaf when quantifying acclimation potential of tree leaves, and indicate that the historical use of leaflets to represent species with compound leaves under-estimated the acclimation potential when compared to species with simple leaves.
