Background: Amaranthus is a critical genus from a taxonomic point of view because of its high phenotypic variability, which has led to nomenclatural disorder, misapplication of names, and erroneous species identification. As a whole, floristic and taxonomic studies on this genus are still incomplete. Objectives: The main objective was to record the North American species Amaranthus palmeri in Tunisia for the first time and to point out a second occurrence for Africa. At the same time, we highlight some nomenclatural confusion concerning the name A. palmeri var. glomeratus which appears to be untypified and which should be treated at species rank. Method: The work is based on field surveys, analysis of relevant literature and examination of specimens preserved in the herbaria GH, FI, HFLA, K, MICH, NEBC, NY, MO, P, RO, US, and the Herbarium of Bizerta University. Results: A population of Amaranthus palmeri was discovered in Bizerta Province, representing the first record for the national flora. This record also represents the second record for Africa. Morphological characters, as well as ecological data are provided. Nomenclatural notes are provided for A. palmeri var. glomeratus (lectotype at GH, here designated; isolectotypes at MICH and US), and a new name (A. sonoriensis) is proposed. Conclusion: Amaranthus palmeri is an alien species in Tunisia, growing along roadsides and in public gardens. Future monitoring of the populations found will be necessary to verify possible naturalisation and spreading of A. palmeri in Tunisia. If this happens, actions for eradication of the plants will be necessary.

Abstract Amaranthus spinosus L. (Amaranthaceae s.l.), a species native to the Neotropics, has been found in four localities (Bizerta, Bir Bouregba, Hammamet, and Nabeul) of N. Tunisia. Our discovery represents the first record at national level, and the second one for N. Africa. Morphological characters and ecological data are given. Nomenclatural notes are provided for the name A. diacanthus, which was regarded by some authors as heterotypic synonym of A. spinosus. A neotype is designated in the present paper based on a specimen preserved at LSU.

The study of the variability of 22 morphological characters in 5 populations of Solidago canadensis L. s. l., growing in the city of Minsk and its environs, was carried out. Comparison of the obtained data with previously published information on the nature and range of variability of the North American taxa Solidago subsect. Triplinerviae showed that plants growing on the territory of the Republic of Belarus cannot be unambiguously assigned to any of the North American species by the combination of morphological characters. Compared to North American taxa, the plants of the studied populations have a significantly more powerful habitus (a large average plant height, longer and in many populations broader mid stem leaves, most often a larger inflorescence), intermediate in comparison with S. canadensis s. str. and S. altissima s. str. and significantly different from both North American species, the length of involucres and the length of tubular flowers, significantly longer outer phyllaries, shorter straps of ray florets, larger ovaries of ray florets, but their shorter pappus, a significantly smaller number of disc florets. The disc florets have significantly larger teeth compared to S. canadensis s. str. and S. altissima s. str. The data obtained confirm the point of view of Hildemar Scholz, according to which the invasive goldenrod, which is currently widely distributed throughout Europe, are of European origin. Most likely, they are either stabilized hybrids that arose during breeding due to the crossing of several North American species, or arose as a result of spontaneous mutation and further selection under natural conditions.

Chewing lice were collected from small shorebirds (Charadriformes: Scolopacidae) overwintering in foraging grounds of coastal Ecuador. On 27 occasions at least one louse (3.7%) was collected from six host species. Based on external morphological characters, at least two species of chewing lice could be preliminary identified (family: Menoponidae), including Actornithophilus umbrinus(Burmeister, 1842) and Austromenopon sp. A. umbrinus was found in the Western Sandpiper (Calidris mauri), Least Sandpiper (C. minutilla), Stilt Sandpiper (C. himantopus), Semipalmated Plover (Charadrius semipalmatus) and Wilson's phalarope (Phalaropus tricolor), whileAustromenopon sp. is presumably the first record collected from the Surfbird (Aphriza virgata). These findings indicate that the distribution of these chewing lice species covers at least the regions around the equator (latitude 0°) until the Arctic in the north, but probably also includes the entire winter distribution area of the host species. This is the first study of chewing lice from Ecuador's mainland coast and more research is required to understand the host-parasite ecology and ectoparasitic infection in shorebirds stopping over the region.

The class Echinoidea contains among the best-known echinoderms. The group has left the most complete fossil record of this phylum, and contains about 1000 living species, of which 51 are recorded along the Brazilian coast. Although the first record of echinoids in Brazil was made 369 years ago, the knowledge of this fauna remains quite unsatisfactory from a taxonomic and ecological point of view, particularly in the north and northeastern regions of the country. This study provides the first annotated list of echinoids from northeastern Brazil. The studied material largely belongs to collections of the Federal University of Paraíba (CIPY), Federal University of Sergipe (LABIMAR-UFS), Federal University of Bahia (MZUFBA), University of São Paulo (MZUSP), and National Museum of the Federal University of Rio de Janeiro (MNRJ). Thirty-two species from 29 genera, 18 families, and 10 orders were identified. Descriptions of species are provided. Highest diversities of Echinoidea were encountered for the states of Bahia (19 spp.), Alagoas (11 spp.), Paraíba (10 spp.), Ceará (7 spp.), Rio Grande do Norte (7 spp.), and Pernambuco (6 spp.). On the basis of the data analysed, Maranhão (2 spp.), Piauí (2 spp.), and Sergipe (3 spp.) have the lowest diversity. Sandy substrates and depths below 10 m were the least sampled areas over the continental shelf. Although the studied species are common, some taxonomic problems were encountered and discussed. We also provide ecological information and comments on status of the species from the studied region. As a result of this inventory, we were able to provide the first assessment of the echinoid fauna of northeastern Brazil.

Alcataenia campylacantha (Krabbe, 1869) is redescribed and reported for the first time from pigeon guillemots, Cepphus columba Pallas, in Alaska. Specimens of this cestode were also found in black guillemots, Cepphus grylle (Linnaeus) at Point Barrow, Alaska. There were no substantial differences in morphological characters between populations of this cestode from the North Atlantic and North Pacific basins. Additionally, Alcataenia sp. indet. is reported, with a partial description, from Kittlitz's murrelets, Brachyramphus brevirostris (Vigors), in Alaska. This constitutes the first record of dilepidid cestodes from birds of the genus Brachyramphus Brandt.

An entomological survey was carried out in the municipalities of Juchique de Ferrer and Colipa in the north-central area of the State of Veracruz, Mexico, where some human cutaneous leishmaniasis cases have been recorded. These sampling efforts were undertaken to identify potential vectors of Leishmania species in that area. A total of 123 specimens were obtained, corresponding to one species of the Bruchomyiinae genus Nemapalpus Macquart, and six species of the Phlebotominae genus Lutzomyia França. Additional morphological characters of the poorly known male of Nemapalpus dampfianus Alexander and a description of Lutzomyia leohidalgoi sp. nov., based on male and female characteristics, are presented with illustrations. This is the first record from Veracruz of Nemapalpus dampfianus Alexander, Lutzomyia serrana (Damasceno & Arouck) (species group Verrucarum), Lutzomyia (Psathyromyia) cratifer (Fairchild & Hertig), and Lutzomyia (Helcocyrtomyia) oppidana (Dampf). Lutzomyia (Lutzomyia) cruciata (Coquillett) and L. (Psathyromyia) shannoni (Dyar) are anthropophilic species already known from Veracruz.

The genus Microgecko Nikolskii, 1907 (Gekkonidae) currently includes eight species distributed from western Iran to north-western India and Pakistan. During field research in Iraq, we found a population of the genus near to the Darbandikhan Lake in the north-eastern part of the country. Because members of the genus are characterized by a higher level of morphological and genetic diversity, we investigated the population using both morphological and molecular approaches. The phylogenetic analyses based on a fragment of the mitochondrial marker cytochrome b and morphological characters showed that our investigated population belongs to M. helenae fasciatus. This is the first record of the genus and species for Iraq. Moreover, the phylogenetic structure within M. helenae shows divergences that suggest the elevation of M. h. fasciatus to species level.

Seven new freshwater ameirids were discovered in the Australian subterranean habitats, six of which would fit into the present unsatisfactory diagnosis of the genus Stygonitocrella Reid, Hunt & Stanley, 2003. Two of them were discovered in Pioneer Valley, Queensland, representing the first record of this genus in eastern Australia. Four other species were collected from the Pilbara region in Western Australia, the same region in Australia where the first three representatives of this genus were reported. An additional new species was collected in the Kimberley region in Western Australia and could not be assigned to the revised genus Stygonitocrella, but has some remarkable similarities with species that were in the past considered to be members of this genus. In order to assess the most natural allocation of these ameirid taxa, a revision of the genus Stygonitocrella was made, based on a cladistic approach by using 57 phylogenetically informative morphological characters. The phylogenetic analysis revealed the presence of six monophyletic groups, giving ground for the establishment of six new genera, three of them created to accommodate a single new Australian species: Kimberleynitocrella billhumphreysi gen. et sp. nov. from several bores in the Argyle Diamond Mine and Ord River in the Kimberley region in Western Australia, Gordanitocrella trajani gen. et sp. nov. from three different localities in the Pilbara region in Western Australia, and Lucionitocrella yalleenensis gen. et sp. nov. from a single bore on the Yalleen Station, also in the Pilbara region in Western Australia. All three new Australian genera have a basal position on the phylogenetic tree, because they share several plesiomorphic characters; nevertheless they are well defined by the combination of apomorphic and plesiomorphic features. The generic diagnosis of Stygonitocrella is emended and the genus redefined to include only four species: S. montana (Noodt, 1965) from Argentina (the type species), S. dubia (Chappuis, 1937) and S. guadalfensis Rouch, 1985 from Spain and S. sequoyahi Reid, Hunt & Stanley, 2003 from the United States. The Cuban S. orghidani (Petkovski, 1973) was left as incertae sedis in this genus. The subgenus Fiersiella Huys, 2009 is established as a junior subjective synonym of Stygonitocrella. Generic diagnoses are emended for the monospecific Australian genus Inermipes Lee & Huys, 2002, the monospecific Japanese genus Neonitocrella Lee & Huys, 2002 and the North American genus Psammonitocrella Huys, 2009, that contains two species. The genus Reidnitocrella gen. nov. is erected to accommodate three closely related central Asian species: R. tianschanica (Borutzky, 1972) comb. nov., R. pseudotianschanica (Sterba, 1973) comb. nov., and R. djirgalanica (Borutzky, 1978) comb. nov. Also, after carefully examining the available published information on R. tianschanica another new species is recognized in this genus: R. borutzkyi sp. nov. The genus Eduardonitocrella gen. nov. is erected for the Mexican E. mexicana (Suárez-Morales & Iliffe, 2005) comb. nov. The newly established genus Megastygonitocrella gen. nov. is the largest one in this group of freshwater ameirids, containing the following 11 species: M. trispinosa (Karanovic, 2006) comb. nov. (type species), M. bispinosa (Karanovic, 2006) comb. nov., M. unispinosa (Karanovic, 2006) comb. nov., M. ecowisei sp. nov., M. dec sp. nov., M. pagusregalis sp. nov., M. kryptos sp. nov., M. karamani (Petkovski, 1959) comb. nov., M. petkovskii (Pesce, 1985) comb. nov., M. ljovuschkini (Borutzky, 1967) comb. nov. and M. colchica (Borutzky & Michailova-Neikova, 1970) comb. nov. The first five species are endemic to the Pilbara region in Western Australia, the next two are described from Queensland, M. karamani is known from Slovenia, M. petkovskii from Greece, while the last two species are endemic to the Caucasus. A Tethyan origin for this genus is here hypothesized. New locality data is presented for the first three species, which revealed that M. trispinosa is the most common and widely distributed member of this group (although restricted to a single Australian region), while M. bispinosa and M. unispinosa are short range endemics. A key to species is provided for each polytypic genus, as well as a key to genera of Stygonitocrella s. l.

Guwahati derives its name from the Assamese word “Guwa” means areca nut and “Haat” means market. However, the modern Guwahati had been known as the ancient Pragjyotishpura and was the capital of Assam under the Kamrupa kingdom. A beautiful city Guwahati is situated on the south bank of the river Bramhaputra. Moreover, It is known as the largest city in the Indian state of Assam and also the largest metropolis in North East India. It has also its importance as the gateway to the North- East India. Assamese and English are the spoken languages in Guwahati.  In 1667, the Mogul forces were defeated in the battle by the Ahom forces commanded by Lachut Barphukan. Thus, in a sense Guwahati became the bone of contention among the Ahoms, Kochas and the Moguls during the medieval period.  Guwahati the administrative headquarters of Lower Assam with a viceroy or Barbhukan was made by the Ahom king.  Since 1972 it has been the capital of Assam. The present paper will discuss the changes happened in Guwahati over the period of late 1970s till the present time. It will focus on the behavior of people, transformed temples, Panbazar of the city, river bank of Bramhaputra, old Fancy Bazaar, chaotic ways, festivals and seasons including a fifth man made season etc. It will also deal how over the years a city endowed with nature’s gifts and scenic views, has been changing as “a dirty city”. Furthermore, it will also present the insurgencies that have barged into the city. The occurrence of changes will be discussed through the perspective and point of view of Srutimala Duara as presented in her book Mindprints of Guwahati.

In Austria approximately 70% of the population is connected to sewerage and to biological waste water treatment plants. Whereas the urban areas are already provided with these facilities to a very high extent, effort is still needed in rural areas to meet the requirements of the Austrian legislation. The way, this task should be solved has provoked much controversy. It is mainly the question, whether centralised or decentralised sewage disposal systems are preferable from the ecological and economical point of view, that became a political issue during the last 5 years. The Institute for Water Quality and Waste Management was asked to elaborate a waste water management concept for the Lainsitz River Basin, a mainly rural area in the north of Austria discharging to the Elbe river. Both ecological and economical aspects should be considered. This paper presents the methodology that was applied and the criteria which were decisive for the selection of the final solution.
