This paper is a catalog of the Ephemeroptera known from the British Crown Colony of Hong Kong. It includes all known references for each species, along with an indication of the type localities and depositions of type specimens. For each reference the stage (male, female, or nymph) is indicated if relevant. Keys which include the species also are indicated. The recorded distribution for each species is listed. For each genus are given the reference to the original description, information on the type species, and any synonyms. Abbreviations of places of type deposition are as follows: (BMNH), British Museum (Natural History), London; (Cornell), Cornell University, Ithaca, New York; (DEI), Deutsches Entomologisches Institut, Eberswalde; (Hamburg), Zoologisches Staatsinstitut und Zoologisches Museum, Hamburg; (Hsu), personal collection of Y.-C. Hsu [the late Prof. Hsu indicated (personal communication) that because of events in China over the past few decades these specimens should be considered destroyed or lost]; (Utah), University of Utah, Salt Lake City. Although the taxonomic knowledge of the Hong Kong mayflies is still somewhat sketchy, there are substantial ecological studies ongoing at this time. Therefore, in order to facilitate future studies and comparisons of data, I have included in this catalog the "morphospecies" of Dudgeon (1982a, b, 1983, 1984a, b). The reader should be aware that many of the taxonomic assignments of these morphospecies are preliminary and actual placement will have to await future taxonomic studies. This paper is one in a continuing series of catalogs of the Ephemeroptera (cf. Hubbard & Peters 1978, Hubbard & Pescador 1978, Hubbard & Savage 1981, Hubbard 1982a,b)....
This paper updates and summarizes the ant fauna of Alachua County, Florida, with two basic objectives. The first objective is presentation of a current, documented check-list consistent with existing taxonomy and an insight on species groups where taxonomic changes are likely in subsequent revisions. The second objection objective seeks to identify changes in the fauna since Van Pelt’s pioneer survey of 1948, and provide a basis for similar comparisons in the future. The county consists of 902 square miles in north-central Florida and embraces essentially all inland habitats of the northern peninsula. This rich habitat variability is reflected in its ant fauna of 110 species. Few other regions of comparable size and latitude support a larger ant diversity also documented in part for greater than 50 years. A review of the earlier work, current taxonomic authorities, and questionable or rejected records precede the new list....
The only lists of Hydrophiloidae (Coleoptera: Hydrophilidae, Helophoridae, Hydrochidae, and Hydraenidae) from the mid-Atlantic region are Ulke (1902) who reported 46 species from the District of Columbia and Matta (1974) who presented keys and short descriptions for the 49 aquatic species of Hydrophilidae of Virginia. The following checklist records 103 species (75 aquatic) from Maryland. Comparable lists of aquatic species for other states are as follows: 53 species recorded from Florida by Young (1954); 20 species recorded from Ithaca, New York by Swenson (1982); 67 species from North and South Carolina by Brigham (1982); and 47 species from Illinois by Wooldridge (1967). Hatch (1965) recorded 128 species (of all habitats, 102 aquatic) from the Pacific Northwest; and 88 species (67 aquatic) reported from New York by Leng (1928)....
The only published checklist of the Hydradephaga from the Maryland area is Ulke (1902) who records 65 species from the District of Columbia. The present paper lists 121 species as occurring in Maryland. Comparable lists for other states are as follows: Young (1954), 120 species from Florida; Folkerts (1978), 120 species from New York; and Brigham (1982) and Sanderson (1982), 115 species from North and South Carolina. Some of the identifications are questionable until generic revisions are completed. This is especially true of Hydroporus and Gyrinus....
The generic name Brachycoryna was first published by Guerin-Meneville (1844) who at that time also described B. pumila which was the only included species (type species by monotypy). The locality data given by Guerin's material is "Carthagene" (Cartagena, Columbia). Guerin correctly receives authorship of Brachycoryna since a single combined description of a new genus and new species published before 1930 is considered an "indication" for each name (Intern. Code 2001. Nomen., Article 12). Some authors (Weise, 1911 a,b; Papp, 1953) had assigned authorship to Baly (1885) who published the first generic description and reported B. pumila from Mexico, Guatemala, and Nicaragua. There have only been two other generic descriptions published: Weise (1911b) and Monros and Viana (1947)....
Descriptions of species in the genus Sclerosococcus are primarily based on the female morphology (McKenzie 1958, Lambdin 1980). The lack of descriptions for males is attributed to their brief seasonal appearances (lasting only a few hours) and their small size that makes collection of adult specimens difficult. As a result, adequate descriptions for only a few males of Asterolecaniidae are available for comparisons. Of those species where males are known, most descriptions are of the tests or general morphological aspects (Russell, 1941). The most comprehensive descriptions for adult males in the family were provided for Asterolecanium proteae (Giliomee 1968) and for two species of Grammococcus (Miller and Lamdin 1978). The genus Sclerosococcus contains 4 species known from the Neotropical Region where they feed on bromelid hosts. Until now, no reference was made as to the existence of males of the species. My objective was to provide a description of the adult male of this rare species to better define the taxa. Measurements and illustration were made by microscopic examination of the allotype male. Terminology used to describe the external morphology, with few exceptions, was adapted from Theron (1958). All measurements are presented in micrometers....
The genera Paratella and Sephena were established by Melichar (1902) for complexes of species having distribution principally in New Guinea. However, three of Melichar’s new species of Paratella, i.e., fumaria, fusconigra and modesta, were known only from localities in Australia and/or New Zealand. Kirkaldy (1906) described Sephena argue, cinerea and rubida from specimens collected in Australia. He commented that they had the appearance of Paratella while having the characters of Sephena assigned by Melichar. Melichar (1923) and Metcalf (1957) each retained the above named species in Paratella and Sephena The type specimens of the species named above were examined in connection with my research on Kirkaldy and Melichar types, results of which are given in articles that have been submitted for publication elsewhere. To avoid duplicate citation of new synonymies, all synonymies given in this article should be considered to have prior designation by Medler, in press....
Mit Erscheinen dieses Hefts von "Egge-Weser" besteht das Lehrgebiet Tierökologie im Studiengang Landespflege der Uni-GH Paderborn drei Jahre. Lehre, Sammlung und Lehrpark Das Lehrprogramm verläuft im Wesentlichen unverändert wie bei GERKEN (1984) beschrieben. Ergänzend wurde ein Vorlesungsteil 'Hydrobiologie' eingebaut, der zugleich als Serviceleistung für Studenten des Studiengangs Wasserwirtschaft jeweils im Wintersemester angeboten wird. Teile unserer im Aufbau befindlichen Lehrsammlung werden zurzeit für eine allgemein zugängliche Ausstellung aufbereitet, der auch ein größeres Aquaterrarium angegliedert sein wird. Der Auf- und Ausbau der Sammlung wird wesentlich von Spendengeldern (vor allem Höxteraner Firmen) getragen. Im Lehrpark wurden die Arbeiten zur Herrichtung verschiedener Kleingewässer fortgesetzt, wozu unter anderem Spenden von Ton, Kalkmergel und Buntsandsteinbruch wertvolle Hilfe leisteten. An Kleingewässern stehen somit im Rohausbau je ein Buntsandstein-, Kalkmergel-, Lehmund Hilston-Teich zur Verfügung. Nach Möglichkeit soll 1986 ein Torfschlamm-Teich hinzukommen. Die Pflege der Teiche erfolgt durch Mitarbeiter der Ökologischen Arbeitsgemeinschaft unserer Hochschule. Ein bis zu fünf Meter breiter Streifen um die Teiche ist spontan ankommender Vegetation 'reserviert'. Das übrige Umfeld wird als 1-2-schürige Extensivwiese gepflegt....
Annuelle und perenne Pflanzen unterscheiden sich in ihren Überlebensstrategien dadurch, dass erstere einem Rhythmus von "Katastrophen", wie mechanischen Störungen oder klimatisch ungünstigen Perioden, durch "katastrophale" Änderungen ihres Lebenszustandes ausweichen. Die Perennen begegnen den "Katastrophen" durch physiologische Anpassungen. Man könnte diese beiden unterschiedlichen Antwortmuster als "differenzierend" und "integrierend" umschreiben. Anhand eines kleinen Datensatzes (43 Aufn.) von Mauervegetation aus dem mediterranen Teil des atlantischen NW-Spaniens wird exemplarisch gezeigt, wie diese unterschiedlichen Strategien verwendet werden, um einige Aspekte des "Gesamtsystems" Mauervegetation zu interpretieren....
