Color Change of Gemstones by Exposure to Gamma Rays
2015 International Nuclear Atlantic Conference - INAC 2015 São Paulo, SP, Brazil, October 4-9, 2015 ASSOCIAÇÃO BRASILEIRA DE ENERGIA NUCLEAR - ABEN ISBN: 978-85-99141-06-9 COLOR CHANGE OF GEMSTONES BY EXPOSURE TO GAMMA RAYS Giovanna L. C. de Lima1 and Fernando S. Lameiras2 1 Centro de Desenvolvimento da Tecnologia Nuclear (CDTN) Campus da UFMG - Pampulha Av. Antônio Carlos 6627 31270-901 Belo Horizonte, MG [email protected] 2 Centro de Desenvolvimento da Tecnologia Nuclear (CDTN) Campus da UFMG - Pampulha Av. Antônio Carlos 6627 31270-901 Belo Horizonte, MG [email protected] ABSTRACT A gem is appreciated by collectors and, when polished, widely used for jewelry manufacturing. For example, when quartz naturally or artificially acquires a color it becomes a gemstone (smoky quartz, morion, citrine, amethyst, or prasyolite). The presence of chromophore elements in a quartz sample was analysed by Fourier transform infrared spectrometry (FTIR). With a semi-quantitative analysis of the absorption FTIR spectra, it was possible to predict if colorless quartz has the potential to develop color when exposed to ionizing radiation and heat. Specific absorption bands show the presence of chromophore elements in quartz such as aluminum, iron, hydrogen, sodium, or lithium. Considering the ratio of the heights of the absorption bands of these elements, it was possible to predict the color quartz can develop. Samples of irradiated dark and light violet fluorites were analyzed by FTIR and energy-dispersive X-rays spectroscopy. The light violet samples has higher content of calcium relative to fluorine, as well higher content of hydroxyl, probably replacing fluorine in crystal lattice. -
Distribution and Population Density of the Endangered Cauca Guan Penelope Perspicax
Bird Conservation International (2006) 16:299–307. ß BirdLife International 2006 doi: 10.1017/S0959270906000475 Printed in the United Kingdom Distribution and population density of the Endangered Cauca Guan Penelope perspicax GUSTAVO H. KATTAN, ADRIANA LEO´ N, GERMA´ N CORREDOR, WILLIAM BELTRA´ N and MO´ NICA PARADA Summary The original 24,900 km2 distribution of the Cauca Guan Penelope perspicax is currently reduced to less than 750 km2. In addition, forest within this range is fragmented and populations are isolated. We conducted surveys to determine the presence of the Cauca Guan at several locations within its present range, and mapped all known localities with guan records. Cauca Guan populations are confirmed to occur at only four sites, and the guan is absent from several localities with historic records. Some sites where the Cauca Guan is potentially present are highlighted. In particular, the possible existence of populations on the Pacific slope of the Andes requires confirmation, since a large habitat block is available. Population density estimates were obtained in two protected areas. In Yotoco Forest Reserve (559 ha) we estimated 8.6 guans km22. At Otu´ n-Quimbaya Flora and Fauna Sanctuary (489 ha), guans fed seasonally on leaves of Chinese ash Fraxinus chinensis, an exotic tree planted in a revegetation programme. Seasonal densities in ash plantations were over 100 guans km22, whereas in mixed forest, mean density was 41.6 birds km22. Ash has apparently become a key resource for this population. Although these two populations are within protected areas and have relatively high densities, they are small and isolated and require continued monitoring. -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

DOI: http://dx.doi.org/10.15446/abc. v25n1.77442 ABSTRACT Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families. -

Breeding Biology of Yellow-Browed Antbird Hypocnemis Hypoxantha
Daniel M. Brooks et al. 156 Bull. B.O.C. 2016 136(3) Breeding biology of Yellow-browed Antbird Hypocnemis hypoxantha by Daniel M. Brooks, Pablo Aibar, Pam Bucur, Ron Rossi & Harold F. Greeney Received 17 February 2016 Summary.—We provide novel data concerning the nests, eggs and parental care of Yellow-browed Antbird Hypocnemis hypoxantha based on two nests in eastern Ecuador and Peruvian Amazonia, one of which was video-taped. Both adults participated in incubation, with earliest and latest feeding events at 06.11 h and 17.22 h, respectively. Feeding behaviour is described, with intervals of 1–114 minutes (mean = 38.3 minutes) and tettigoniid cicadas the primary prey. Nestlings frequently produced faecal sacs (interval range = 4–132 minutes, mean = 37.8 minutes) immediately following food delivery, and the sac was always carried from the nest by an adult. Two events involving a parent bird being chased from the nest are described, the first involving a male Fulvous Antshrike Frederickena fulva. Systematics are discussed in light of nest morphology and architecture. Yellow-browed Antbird Hypocnemis hypoxantha is a distinctive Amazonian thamnophilid that comprises two currently recognised subspecies: nominate hypoxantha in western Amazonian lowland and foothill forests from southern Colombia south to central Peru, and H. h. ochraceiventris in south-east Amazonian Brazil (Zimmer & Isler 2003). Generally found below 400 m, the nominate subspecies occasionally ranges as high as 900 m (Zimmer & Isler 2003, Ridgely & Tudor 2009). The species’ reproductive biology is almost completely unknown (Zimmer & Isler 2003). Willis (1988) provided a cursory description of a nest with nestlings from Colombia, but included few details of the nest and no description of the eggs or behaviour. -

Figs are potential keystone resources that sustain frugivore communities during periods of scarcity, but studies have produced contradictory results. Over 1 y we monitored the phenology of 206 trees of five Ficus species in a Colombian cloud forest, to test whether figs produced fruit during periods of low overall fruit availability. We also measured fig tree densities in 18 0.5-ha plots and made 190 h of observations at 24 trees of three species to determine whether figs were abundant and consumed by a large proportion of the local frugivores. The five species produced fruit year-round but fig availability varied monthly by orders of magnitude. Fig trees reached comparatively high densities of 1–5 trees ha−1 and were consumed by 36 bird species (60% of the local frugivore assemblage) and three mammal species. -

Yet, it was still too early to experience the real explosion of bird song, which usually happens after dawn. Then, after 05:30 AM, the chorus started when a vocal Great Kiskadee broke the morning silence, followed by the scratchy notes of two Hoffmann´s Woodpeckers, a nesting pair of Inca Doves, the ascending and monotonous song of the Yellow-bellied Elaenia, and the cacophony of an (apparently!) engaged pair of Rufous-naped Wrens. This was indeed a warm welcome to magical Costa Rica! To complement the first morning of birding, two boreal migrants, Baltimore Orioles and a Tennessee Warbler, joined the bird feast just outside the hotel area. Broad-billed Motmot . Photo: D. Ascanio © Victor Emanuel Nature Tours 2 The Best of Costa Rica, 2019 After breakfast, we drove towards the volcanic ring of Costa Rica. Circling the slope of Poas volcano, we eventually reached the inspiring Bosque de Paz. With its hummingbird feeders and trails transecting a beautiful moss-covered forest, this lodge offered us the opportunity to see one of Costa Rica´s most difficult-to-see Grallaridae, the Scaled Antpitta.
