Musky Rat-kangaroos can be classified as frugivo res because fr ui ts and seeds accounted fo r the bul k of their diet th roughout the year (Chapter 3). In addi tion, they scatterhoarded many fruits and seeds, to the benefit of at least some species of plants (Chapters 8 & 9). They consumed most of the available frui ts which had a fleshy pericarp or ani but also included the seeds of some species that did not. They ate fruits from over half the species producing fruits on my study site, many of those they did not eat were wind dispersed, housed in hard, indehiscent pods or had furry. dehiscent pods. In addition, some fleshy drupes were not consumed. Like many other frugivores, Musky Rat-kangaroos supplemented their diet from other sources, particularly when the seasonal availabil ity of fruits is at its min imum (see Terborgh 1983). During the late wet, co ld an d early dry seasons, when frui t abundance was mini mal, their search effort was random with respect to fr ui t fall s (Figure 3.8; Table 3.2).

  • (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.

We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.

In order to characterize the inflorescence and further knowledge of this family, a morphoanatomical study was carried out of the palm S. inajai in a green area of the Campus of the Federal University of Amazonas - UFAM, Manaus, Amazonas. The inflorescences are branched to one order, pedunculate, and interfoliar, measuring 62-82 cm in length, with woody bracts with longitudinal grooves on the external surface, and flowers in triads. The number of flowers to each inflores- cence varies from 5,904 to 17,316 for staminate flowers, and from 180 to 3,528 for pistillate flowers. Staminate flowers with six anthers and one vascular bundle each; three-lobed pistillodium, vascularized pistillodium. Its pistillate flowers have six staminodia joined to form a circle, syncarpic, tricarpellary, trilocular gynoecium, one ovule to each locule, synascidiate in the ovary, and plicated above.

  • Stem Anatomy in the Spiny American Palm Bactris (Arecaceae-Bactridinae)
    Hoehnea 42(3): 567-579, 1 tab., 4 fig., 2015 http://dx.doi.org/10.1590/2236-8906-18/2015 Stem anatomy in the spiny american palm Bactris (Arecaceae-Bactridinae) Tracy Monique Magellan1,4, P. Barry Tomlinson2 and Brett A. Huggett3 Received: 11.02.2015; accepted: 07.05.2015 ABSTRACT - (Stem anatomy in the spiny american palm Bactris (Arecaceae-Bactridinae)). Bactris trunks are made entirely by long sustained primary growth so that mechanical properties develop progressively as the trunk matures. Anatomical features vary throughout the stem so that one small sample is a limited representation. This limits the use for stem histology with systematic purposes. We examined stem anatomy in 17 out of 73 species representing all major sub-generic groups. Stem features do not associate well with the subdivision of the genus. Distinctive structural and developmental features: are the presence of fiber strands independent of the vascular tissues, the modified ground parenchyma with a late formation of air-lacunae, and the early inception of the mechanically significant outer central cylinder. Cell expansion and fiber wall thickening develop as the stem ages, but vary in their expression in stems of different diameter. Our example thus provides an explanation for the difficulty of identifying the systematic position of fossil palm stems. Keywords: biomechanics, fiber development, primary growth, stem anatomy RESUMO - (Anatomia de caule na palmeira espinhosa americana Bactris (Arecaceae-Bactridinae)). Os caules de Bactris são totalmente construídos por um longo e contínuo crescimento primário, de tal modo que as propriedades mecânicas se desenvolvem de maneira progressiva enquanto o caule amadurece. Os aspectos anatômicos variam ao longo do caule, e por isso uma amostra pequena acaba sendo uma representação limitada.
