1 Doc. 8.50 CONVENTION on INTERNATIONAL TRADE
Doc. 8.50 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________ Eighth Meeting of the Conference of the Parties Kyoto (Japan), 2 to 13 March 1992 Interpretation and Implementation of the Convention CRITERIA FOR AMENDMENTS TO THE APPENDICES (The Kyoto Criteria) This document is submitted by Botswana, Malawi, Namibia, Zambia and Zimbabwe. Background The attached draft resolution is intended to replace the existing criteria for listing species in the appendices of the Convention, for transferring species between the appendices and for deletion of species from the appendices. In addition, it incorporates and consolidates the provisions of various other Resolutions relevant to this topic and provides a basis for their removal from the list of Resolutions of the Convention. Since the Berne Criteria (Resolutions Conf. 1.1 and 1.2) have formed the basis for amendments to the appendices of the Convention since 1976, it is necessary to provide substantial justification for their replacement. General issues International trade 1. CITES was established to address international trade in wild fauna and flora. It is unable to influence the survival of species which are not exploited for trade or species which are exploited within States for domestic consumption. Perhaps the greatest threat to species is the loss or fragmentation of habitats in the countries where they occur: this problem has to be addressed through other measures. International trade may be one of the less important factors influencing the survival of the majority of species and this should be recognized. CITES is an international conservation treaty with a circumscribed role limited to those species which are genuinely threatened with extinction, or which could become so, in which there is significant international trade. -

The sensory drive hypothesis states that these 12 traits evolved and vary due to interactions with each other, the environment, and signal 13 receiver. However, interactions between colorful ornaments and courtship behaviors, 14 specifically in relation to environmental variation, remain poorly understood. We studied 15 male iridescent plumage (gorgets), display behavior, and sun orientation during courtship 16 flights (shuttle displays) in broad-tailed hummingbirds (Selasphorus platycercus), to 17 understand how these traits interact in both space and time to produce the perceived 18 coloration of males. We also tested how gorget coloration varies among males based on 19 their plumage, behavioral, and morphological characteristics. In contrast with previous 20 work on other animals, we found that displaying males did not directionally face the sun, 21 but instead displayed on a continuum of solar orientation angles. The gorgets of males 22 who tended to face the sun during their displays appeared flashier (i.e. exhibited greater 23 color/brightness changes), brighter, and more colorful, whereas the gorgets of males who 2 Broad-tailed hummingbird coloration and sun orientation 24 tended to not face the sun were more consistently reflective (i.e. -
Song and Plumage Evolution in the New World Orioles (Icterus) Show Similar Lability and Convergence in Patterns

Here we reconstruct the evolution of song in the New World orioles (Icterus) and compare patterns of vocal evolution to previously reconstructed patterns of change in plumage evolution in this clade. Individual vocal characters exhibit high levels of homoplasy, reflected in a low overall consistency index (CI = 0.27) and retention index (RI = 0.35). Levels of lability in song are comparable to those found for oriole plumage patterns using the same taxa (CI = 0.31, RI = 0.63), but are strikingly dissimilar to the conservative patterns of change seen in the songs of oropendolas (Psarocolius, Ocyalus;CI= 0.82, RI = 0.87), a group closely related to the orioles. Oriole song is also similar to oriole plumage in exhibiting repeated convergence in overall patterns, with some distantly related taxa sounding remarkably similar. -

Santa Rosa 11315, La Pintana, Santiago, Chile. 2 AvesChile (Chilean Ornithologists' Union), Santiago, Chile. E-mail: Cristián F. Estades∙[email protected] Abstract ∙ The Chilean Woodstar (Eulidia yarrellii) is a critically endangered hummingbird of the Atacama desert in northern Chile, with a population estimate of around 320 individuals in 2017. To generate useful information for the design of population-recovery actions, we conducted a study of the nesting ecology of the species between 2006 and 2008. Our specific goals were to provide a quantitative descrip- tion of the species breeding habitat, to describe the basic breeding biology of the species, and to assess the current levels of nesting success. Most of our work was conducted in the valleys of Azapa and Vitor, two of the three last valleys where the species is known to persist. Alt- hough we recorded some juveniles in Azapa, we only observed the species nesting in one site in Chaca (Vitor valley), in a small (1.4 ha) olive grove where 13–20 simultaneous nests were found during the studied breeding seasons. Nesting occurs in September–October, and its tim- ing is apparently synchronized with the flowering of chañar (Geoffroea decorticans). The species has a particularly long breeding period with an average of 48 days (17 d for the egg stage, 31 d for the nestling stage). -

Geographic Variation and Genetic Structure in the Bahama Oriole (Icterus Northropi), a Critically Endangered Synanthropic Species
Geographic variation and genetic structure in the Bahama Oriole (Icterus northropi), a critically endangered synanthropic species Melissa R. Price1,2 , Carl Person3 and William K. Hayes3 1 Department of Natural Resources and Environmental Management, University of Hawai‘i at Manoa,¯ Honolulu, HI, United States 2 Kewalo Marine Laboratory, Pacific Biosciences Research Center, University of Hawaii at Manoa, Honolulu, HI, United States 3 Department of Earth and Biological Sciences, Loma Linda University, Loma Linda, CA, United States ABSTRACT Bird species may exhibit unexpected population structuring over small distances, with gene flow restricted by geographic features such as water or mountains. The Bahama Oriole (Icterus northropi) is a critically endangered, synanthropic island endemic with a declining population of fewer than 300 individuals. It now remains only on Andros Island (The Bahamas), which is riddled with waterways that past studies assumed did not hinder gene flow. We examined 1,858 base pairs of mito- chondrial DNA sequenced from four gene regions in 14 birds (roughly 5% of the remaining population) found on the largest land masses of Andros Island (North Andros and Mangrove Cay/South Andros). We sought to discern genetic structuring between the remaining subpopulations and its relationship to current conservation concerns. Four unique haplotypes were identified, with only one shared between the two subpopulations. Nucleotide and haplotype diversity were higher for the North Andros subpopulation than for the Mangrove Cay/South Andros subpopulation.

2017 City of York Biodiversity Action Plan
CITY OF YORK Local Biodiversity Action Plan 2017 City of York Local Biodiversity Action Plan - Executive Summary What is biodiversity and why is it important? Biodiversity is the variety of all species of plant and animal life on earth, and the places in which they live. Biodiversity has its own intrinsic value but is also provides us with a wide range of essential goods and services such as such as food, fresh water and clean air, natural flood and climate regulation and pollination of crops, but also less obvious services such as benefits to our health and wellbeing and providing a sense of place. We are experiencing global declines in biodiversity, and the goods and services which it provides are consistently undervalued. Efforts to protect and enhance biodiversity need to be significantly increased. The Biodiversity of the City of York The City of York area is a special place not only for its history, buildings and archaeology but also for its wildlife. York Minister is an 800 year old jewel in the historical crown of the city, but we also have our natural gems as well. York supports species and habitats which are of national, regional and local conservation importance including the endangered Tansy Beetle which until 2014 was known only to occur along stretches of the River Ouse around York and Selby; ancient flood meadows of which c.9-10% of the national resource occurs in York; populations of Otters and Water Voles on the River Ouse, River Foss and their tributaries; the country’s most northerly example of extensive lowland heath at Strensall Common; and internationally important populations of wetland birds in the Lower Derwent Valley. -
Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.
