HARBACH~ Walter Reed Biosystematics Unit, Department of Entomology, Walter Reed Army Institute of Research, Washington, DC 20307-5100. ABSTRACT. A new subgenus, Peytonulus, of the genus Sabethes Robineau-Desvoidy is estab- lished for seven species previously included in the subgenus Sabethinus Lutz. The subgenus is contrasted with the other subgenera of Sabethes and the type species is illustrated.

Perimetral, 1901, Montese, Belém-PA, Brazil. *Programa de Capacita- ção Institucional (PCI-CNPq). 3Author for correspondence, email: [email protected] Abstract Passiflora echinasteris from a secondary vegetation area on the Great Curve of the Xingu River, in the Brazilian Amazon, is newly described. It belongs to the series Serratifoliae with three other Brazilian species. The new species is illustrated and its affinities with related species are discussed, and a key to the Brazilian species of the series is provided. Key words: Brazilian Amazon, Belo Monte, Passion flower, Xingu River Introduction Passiflora Linnaeus (1753: 955) is a genus that could be easily used to demonstrate the need of taxonomic studies for several further groups of plants in the Amazon. As a result of only a few isolated taxonomic studies in the Brazilian Amazon, the number of new species of Passiflora recently increased as showed by Koch et al. (2013, 2014), as well as the register of new records. During the activities of the project “Survey and Scientific exploration of the Flora of the UHE Belo Monte” in the Xingu region, several individuals of a Passiflora of the series Serratifoliae Killip ex Cervi (1997: 30) were found. -

PhytoKeys 119: 117–136. https://doi.org/10.3897/phytokeys.119.30790 Abstract A new species, Allium albanicum, is described and illustrated from Albania (Balkan Peninsula). It grows on serpentines or limestone in open rocky stands with a scattered distribution, mainly in mountain loca- tions. Previously, the populations of this geophyte were attributed to A. meteoricum Heldr. & Hausskn. ex Halácsy, described from a few localities of North and Central Greece. These two species indeed show close relationships, chiefly regarding some features of the spathe valves, inflorescence and floral parts. They also share the same diploid chromosome number 2n =16 and similar karyotype, while seed testa micro- sculptures and leaf anatomy reveal remarkable differences. -

Listing a Species As a Threatened Or Endangered Species Section 4 of the Endangered Species Act
U.S. Fish & Wildlife Service Listing a Species as a Threatened or Endangered Species Section 4 of the Endangered Species Act The Endangered Species Act of 1973, as amended, is one of the most far- reaching wildlife conservation laws ever enacted by any nation. Congress, on behalf of the American people, passed the ESA to prevent extinctions facing many species of fish, wildlife and plants. The purpose of the ESA is to conserve endangered and threatened species and the ecosystems on which they depend as key components of America’s heritage. To implement the ESA, the U.S. Fish and Wildlife Service works in cooperation with the National Marine Fisheries Service (NMFS), other Federal, State, and local USFWS Susanne Miller, agencies, Tribes, non-governmental Listed in 2008 as threatened because of the decline in sea ice habitat, the polar bear may organizations, and private citizens. spend time on land during fall months, waiting for ice to return.

Activity 3: Six Kingdoms Brochure
Activity 3: Six Kingdoms Brochure Objective: You will demonstrate your knowledge of the six kingdoms of organisms by gathering information (from your class notes, the internet, and the biology textook) and creating a brochure on the six kingdoms in which scientists classify organisms. Your brochure will be organized as follows: 1. Making the Brochure- the brochure is made of one piece of paper. Fold the paper into thirds. 2. Cover- your cover should have a picture and an appropriate title. Your name should be written in the bottom right corner of the cover. 3. Inside the Brochure- inside your brochure, you should have one section for each of six kingdoms. Use the front and back of the paper. Since there will only be five open sections left in the brochure, you should place both the Eubacteria Kingdom and Archaebacteria Kingdom in the same section. You must include the following information for each of the six kingdoms: • Are the organisms unicellular (one cell) or multicellular (many cells) or both? • Do they have a nucleus in their cells? • Do they make their own food or get it from other organisms? • Other important characteristics • A picture or a diagram of sample organisms (one or a few) The Kingdom Fungi The Kingdom Fungi includes some of the most important organisms, both in terms of their ecological and economic roles. By decomposing dead material, they continue the cycle of nutrients through ecosystems. In addition, most plants could not grow without the fungi, or mycorrhizae, that live in their roots and supply essential nutrients. Other fungi provide numerous drugs (such as penicillin and other antibiotics), foods like mushrooms, truffles and morels, and the bubbles in bread (yeast), champagne, and beer. -

The monophyly of the subgenus Leptempis Collin of the genus Empis L. is established on the basis of a male hypopygial character, and the possibility of a close relationship between the subgenera Leptempis Collin, Planempis Frey andKritempis Collin is discussed.

Address for correspondence: Nicolás García, [email protected] DOI https://doi.org/10.1002/tax.12062 Abstract A robust generic classification for Amaryllidaceae has remained elusive mainly due to the lack of unequivocal diagnostic characters, a consequence of highly canalized variation and a deeply reticulated evolutionary history. A consensus classification is pro- posed here, based on recent molecular phylogenetic studies, morphological and cytogenetic variation, and accounting for secondary criteria of classification, such as nomenclatural stability. Using the latest sutribal classification of Hippeastreae (Hippeastrinae and Traubiinae) as a foundation, we propose the recognition of six genera, namely Eremolirion gen. nov., Hippeastrum, Phycella s.l., Rhodolirium s.str., Traubia, and Zephyranthes s.l. A subgeneric classification is suggested for Hippeastrum and Zephyranthes to denote putative subclades. -
