Chrysis Linnaeus, 1761 is a large, cosmopolitan and diverse genus in this family (Chrysidinae, Chrysidini), with over 1100 described species and subspecies and many more to be discovered. A list of twelve species of the genus Chrysis collected in the Fars Province of Iran is presented. Specimens were collected by Malaise traps during 2013-2017. The specimens were identified based on morphological characters mentioned in different taxonomic keys and their original descriptions. Six species: Chrysis amneris Balthasar, 1953, Ch. dawahi Strumia, 2011, Ch. diacantha diacantha Mocsáry, 1889, Ch. laeta Dahlbom, 1854, Ch. santschii Linsenmaier, 1959 and Ch. taurica Mocsáry, 1889 are newly added to the Iranian wasp fauna.

  • 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.

  • List of Animal Species with Ranks October 2017
    Washington Natural Heritage Program List of Animal Species with Ranks October 2017 The following list of animals known from Washington is complete for resident and transient vertebrates and several groups of invertebrates, including odonates, branchipods, tiger beetles, butterflies, gastropods, freshwater bivalves and bumble bees. Some species from other groups are included, especially where there are conservation concerns. Among these are the Palouse giant earthworm, a few moths and some of our mayflies and grasshoppers. Currently 857 vertebrate and 1,100 invertebrate taxa are included. Conservation status, in the form of range-wide, national and state ranks are assigned to each taxon. Information on species range and distribution, number of individuals, population trends and threats is collected into a ranking form, analyzed, and used to assign ranks. Ranks are updated periodically, as new information is collected. We welcome new information for any species on our list.

    Abstract Marcot, Bruce G. 1995. Owls of old forests of the world. Gen. Tech. Rep. PNW- GTR-343. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. A review of literature on habitat associations of owls of the world revealed that about 83 species of owls among 18 genera are known or suspected to be closely asso- ciated with old forests. Old forest is defined as old-growth or undisturbed forests, typically with dense canopies. The 83 owl species include 70 tropical and 13 tem- perate forms. Specific habitat associations have been studied for only 12 species (7 tropical and 5 temperate), whereas about 71 species (63 tropical and 8 temperate) remain mostly unstudied. Some 26 species (31 percent of all owls known or sus- pected to be associated with old forests in the tropics) are entirely or mostly restricted to tropical islands. Threats to old-forest owls, particularly the island forms, include conversion of old upland forests, use of pesticides, loss of riparian gallery forests, and loss of trees with cavities for nests or roosts. Conservation of old-forest owls should include (1) studies and inventories of habitat associations, particularly for little-studied tropical and insular species; (2) protection of specific, existing temperate and tropical old-forest tracts; and (3) studies to determine if reforestation and vege- tation manipulation can restore or maintain habitat conditions. An appendix describes vocalizations of all species of Strix and the related genus Ciccaba. Keywords: Owls, old growth, old-growth forest, late-successional forests, spotted owl, owl calls, owl conservation, tropical forests, literature review.

  • The Impact of Locomotion on the Brain Evolution of Squirrels and Close Relatives ✉ Ornella C
    ARTICLE https://doi.org/10.1038/s42003-021-01887-8 OPEN The impact of locomotion on the brain evolution of squirrels and close relatives ✉ Ornella C. Bertrand 1 , Hans P. Püschel 1, Julia A. Schwab 1, Mary T. Silcox 2 & Stephen L. Brusatte1 How do brain size and proportions relate to ecology and evolutionary history? Here, we use virtual endocasts from 38 extinct and extant rodent species spanning 50+ million years of evolution to assess the impact of locomotion, body mass, and phylogeny on the size of the brain, olfactory bulbs, petrosal lobules, and neocortex. We find that body mass and phylogeny are highly correlated with relative brain and brain component size, and that locomotion strongly influences brain, petrosal lobule, and neocortical sizes. Notably, species living in 1234567890():,; trees have greater relative overall brain, petrosal lobule, and neocortical sizes compared to other locomotor categories, especially fossorial taxa. Across millions of years of Eocene- Recent environmental change, arboreality played a major role in the early evolution of squirrels and closely related aplodontiids, promoting the expansion of the neocortex and petrosal lobules. Fossoriality in aplodontiids had an opposing effect by reducing the need for large brains. 1 School of GeoSciences, University of Edinburgh, Grant Institute, Edinburgh, Scotland, UK. 2 Department of Anthropology, University of Toronto Scarborough, ✉ Toronto, ON, Canada. email: [email protected] COMMUNICATIONS BIOLOGY | (2021) 4:460 | https://doi.org/10.1038/s42003-021-01887-8 | www.nature.com/commsbio 1 ARTICLE COMMUNICATIONS BIOLOGY | https://doi.org/10.1038/s42003-021-01887-8 hat ecological and evolutionary factors affect brain size striking differences between living sciurids and aplodontiids raise in mammals?

A recently excavated site, CA-SAC-47, provides direct evidence of subsistence strategies in the form of faunal and plant remains. This faunal assemblage is compared to direct evidence of subsistence from Delta sites SAC-42, SAC-43, SAC-65, SAC-145, and SAC-329. The results and implications of this direct evidence are used to address site variability and resource selectivity. ___________________________________, Committee Chair Mark E.

This booklet was prepared with funds from the Forest Service Celebrating Wildflowers program, whose goals are to serve our nation by introducing the American public to the aesthetic, recreational, biological, ecological, medicinal, and economic values of our native botanical resources. By becoming more thoroughly acquainted with local plants and their multiple values, we hope to consequently in- crease awareness and understanding of the Forest Service’s management undertakings regarding plants, including our rare plant conservation programs, invasive plant man- agement programs, native plant materials programs, and botanical research initiatives. This booklet is a trial booklet whose purpose, as part of the Celebrating Wildflowers program (as above explained), is to increase awareness of local plants. The Modoc NF Botany program earnestly welcomes your feedback; whether you found the book help- ful or not, if there were too many plants represented or too few, if the information was useful to you or if there is more useful information that could be added, or any other comments or concerns. Thank you. Forest J. R. Gauna Asst.
