Vaasan lyseon kirjasto

Vaasan ensimmäinen suomenkielinen oppikoulu, Vaasan suomenkielinen yksityislyseo,vuoteen 1973 Vaasan lyseo, perustettiin vuonna 1880. Kirjaston toiminta saatiin alkuun paikallisten lahjoitusten turvin. Lahjoittajia olivat mm. kauppiaat A. Hartman ja Oskar Hartman, oikeusneuvosmies J. Kr. Svanljung sekä hovioikeudenneuvos Oskar Rewell. Kirjastoa voi luonnehtia akateemiseksi. Kirjastossa on luonnollisesti oppikirjoja, erityisesti filologian, historian ja luonnontieteiden alalta mutta myös yleisteoksia ja lähdekirjallisuutta opettajien tarpeita varten. Suurimpia aihekokonaisuuksia ovat Suomen historia ja uskonto. Suomen sisällissotaan liittyvää kirjallisuutta on yli 200 nimekettä. Vuonna 1963 kirjastossa oli 9.520 kirjaa, joista 1.911 kuului oppikirjakokoelmaan. Noin 2.500 niistä oli painettu ennen vuotta 1900. Nykyinen kirjasto käsittää noin 4.800 nidettä (120 hyllymetriä), 145 aikakauslehteä ja sarjajulkaisua, karttoja, kuvateoksia ja erillisen kokoelman väitöskirjoja. Valtaosa kirjoista ovat suomenkielisiä. Pieni osa on ruotsin- ja saksankielisiä. Yksittäisiä kirjoja on myös latinan, kreikan, englannin, ranskan ja venäjän kielillä, lähinnä kaunokirjallisuutta. Kirjasto, josta vuosien kuluessa oli tullut historiallinen kokoelma, siirrettiin koulun remontin alta Pohjanmaan museon varastoon 1990-luvulla ja sieltä 2004 Tritoniaan. Kirjat on järjestetty aiheenmukaisiin luokkiin aakkosjärjestyksessä. Luokitus noudattaa pääpiirteissään yleisten kirjastojen luokitusjärjestelmää. Kirjastosta on aiheenmukainen korttiluettelo. Vaasan lyseon entiset oppilaat -yhdistys myönsi rahoitusta kirjakokoelman luettelointiin v. 2015-2016.

Ekenäs seminariums bibliotek

Ekenäs seminarium skötte den finlandssvenska folkskollärarinneutbildningen åren 1871-1974. Seminariets bibliotek flyttades, då skolan upphörde 1974, till Österbottens högskolas bibliotek och därifrån till Tritonia 2001. Samlingen består av ca. 8.000 böcker (207,6 hyllmeter) från olika ämnesområden med betoning på pedagogik, religion, historia och skönlitteratur. Över 90% av litteraturen är på svenska. Samlingen utgör ett intressant tidsdokument över den litteratur som användes i lärarutbildningen från medlet av 1800-talet till grundskolans införande. I samlingen ingår även en stor mängd årsberättelser från olika skolor, skolstatistik och protokoll från olika nationella lärarmöten samt pedagogiska tidskrifter. I samlingen finns även ett litet antal böcker och tidskrifter från Nykarleby seminarium, den finlandssvenska folkskollärarutbildningen, som även den upphörde 1974. Böckerna är ordnade ämnesvis enligt SAB (Sveriges allmänna bibliotek) i huvudklasser och inom dessa i alfabetisk ordning. Samlingen är inte katalogiserad i Tria.

Vaasan tyttölyseon kirjasto

Vaasan tyttökoulun kirjasto kattaa Vaasan suomalaisen tyttökoulun (1891 – 1951) ja Vaasan tyttölyseon (1951 – 1971) säilyneet kirjakokoelmat, yhteensä noin 1700 nimekettä. Näistä vajaa puolet kuuluu opettajien kirjastoon ja hiukan yli puolet oppilaiden kirjastoon. Opettajien kirjastossa tiedon alueet ovat laajasti edustettuina. Tärkeitä aloja ovat luonnollisesti kouluhallinto ja kasvatus sekä koulun oppiaineet. Eniten kirjoja on historian ja yhteiskuntatieteiden aloilta, mutta myös luonnontieteiden ja humanisten alojen kirjallisuutta on runsaasti. Mukana on lisäksi esimerkiksi 1910-luvun alun väitöskirjoja mm. lääketieteen ja oikeustieteen aloilta. Historiallisesti kiinnostavaa aineistoa ovat mm. 1900-luvun ensimmäisten vuosikymmenien naistenlehdet, joilla tuettiin naisten aktiivista osallistumista yhteiskunnallisiin toimintoihin. Opettajille hankittua kaunokirjallisuutta on noin 50 teosta. Oppilaiden kirjastossa yli puolet aineistosta on kaunokirjallisuutta. Tämä kokoelma tarjoaa kiinnostavan kuvan eri vuosikymmenien tyttökirjoista, erityisesti 1940-1960-luvuilta. Oppikirjoissa vahvimpana alana on suomen kieli ja suomalainen kirjallisuus. Pieni osa oppikirjoista on tarkoitettu nimenomaan tyttökouluille. Toukokuussa 2010 siirrettiin opettajien lainakirjaston ja oppilaskirjaston aineistot Tritoniaan. Aineisto on luetteloitu Tritonian tietokantaan Triaan. Pohjanmaan liitto on tukenut kokoelman luettelointityöt.

Samlingen omfattar ca 50 hm och är ordnad enligt undervisningsämne med flest böcker inom modersmålet, matematik samt historia och samhällslära. Samlingen är till största del okatalogiserad.

Trends in fish prey capture by common terns following zebra mussel invasion : do terns track fish species abundance? /

The Common Tern (Sterna hirundo) is a ground nesting colonial seabird. Terns rely primarily on small prey fishes which they obtain through plunge diving for their survival as well as the survival of their offspring during the breeding season. The zebra mussel (Dreissena polymorpha) is a small bivalve mollusk that invaded North American waters in the late 1980's. Through its suspension feeding, the zebra mussel has the ability to alter the entire aquatic ecosystem, ultimately leading to a reduction in pelagic organisms including small prey fish. The objective of the study was to determine what (if any) indirect effects the invasion of the zebra mussel has had on fish prey captured by terns. The study took place in two separate two-year periods, 1990-91 and 1995-96 on a concrete breakwall off the north shore of Lake Erie near Port Colborne, Ontario. Daily nest checks revealed clutch initiation dates, egg-laying chronology, hatching success and morphological egg characteristics (length and breadth). Behavioural observations included time each sex spent in attendance with its brood, the frequency of feeding chicks and the prey species composition and size fed to chicks as well as to females (courtship feeding). Egg sizes did not differ between study periods, nor did feeding rates to chicks, suggesting that food was not a limiting resource. Terns spent less time with their broods (more time foraging) in the 1995-96 period. However, they also had significantly larger broods and fledged more offspring. The time of each individual foraging trip decreased, suggesting that fish were easier to obtain in 1995 and 1996. Lastly, kleptoparasitism rates decreased, suggesting that the costs of foraging (time, energy) actually decreased as fewer birds adopted this strategy to compensate for what I assumed to be a lack of available food (fish). The only significant difference between the periods of 1990, 1991 and 1995, 1996 was a change in diet. Terns delivered significantly fewer rainbow smelt and more emerald shiner in 1995 and 1996. However, the average size of fish delivered did not change. Thus, there was little impact on prey captured by Common Terns in Lake Erie since the invasion of the zebra mussel.

A new genus and new species of fan worms (Polychaeta: Sabellidae) from Atlantic and Pacific Oceans-the formal treatment of taxon names as explanatory hypotheses

Members of Parasabella minuta Treadwell, 1941, subsequently moved to Perkinsiana, were collected during a survey of rocky intertidal polychaetes along the state of Sao Paulo, Brazil. Additional specimens, which are referred to two new species, were also found in similar habitats from the Bocas del Toro Archipelago, Caribbean Panama, and Oahu Island, Hawaii. A phylogenetic analysis of Sabellinae, including members of P. minuta and the two new species, provided justification for establishing a new generic hypothesis, Sabellomma gen. nov., for these individuals. Formal definitions are also provided for Sabellomma minuta gen. nov., comb. nov., S. collinae gen. nov., spec. nov., and S. harrisae gen. nov., spec. nov., along with descriptions of individuals to which these hypotheses apply. The generic name Aracia nom. nov., is provided to replace Kirkia Nogueira, Lopez and Rossi, 2004, pre-occupied by a mollusk.

Utilização da Berberina na Identificação dos Mastócitos do Molusco Anomalocardia brasiliana

Berberine is an alkaloid used as a fluorochrome in the identification of heparin and DNA. Enerback, 1974, described the technique used until today to study granules rich in heparin of vertebrate mast cells. Santos et al., 2003, studied mast cells of the mollusk Anomalocardia brasiliana using biochemical and histological analysis. This work used the fluorescent dye berberine technique to improve characterization of these cells. Mollusk organs (ctenidium and mantle) were processed with routine histological techniques. Tissue sections were treated with berberine 0,02% in redistilled water acidified to pH 4, by the addition of citric acid for 20 minutes. The visualization was made through fluorescence microscopy with ultraviolet region emission. The mast cell fluorescence had a strong yellow color, where cell nuclei appeared more greenish. This result was very similar to the ones reported before. Mast cells are location at the epithelium surface is the same in both organs, mantle and ctenidium. The fluorescence was easily observed in the granules. Therefore, this technique showed to be good and sensitive to study mast cell of invertebrates

Avaliação da atividade turística sobre a composição e a distribuição das macroalgas marinhas nos recifes de Pirangi (Rio Grande do Norte, Brasil)

The reef area of Pirangi beach has been experiencing antropogenic actions, mainly due to tourism activity. In order to evaluate these effects, surveys on seaweeds were conducted at nine stations located over the fringing reef. Benthic community (seaweeds/corals) were identified using the photoquadrat method, with 50 meters random transects located paralleled to the coast. The general categories evaluated in each transect were: rock, sand, seaweeds, corals and mollusks. Data achieved were processed at Coral Point Count with Excel Extensions software. A total of 30 seaweed species, 5 coral species and 1 mollusk species were identified. There was a high dominance of short algae at stations with high tourism pressure, whereas frondose algae usually occurred at places without human interference. Seaweeds with the highest percent cover were composed by Sargassum vulgare (59%), Caulerpa racemosa (47%) and Dictyopteris delicatula (33%). Cluster analyses considering benthic organisms revealed five benthic features: (1) submersed area characterized by a diversified marine flora; (2) area with dominance of Caulerpa racemosa and presence of Millepora alcicornis; (3) area with high cover of Sargassum vulgare; (4) trampling area characterized by bare rocks, short algae and Zoanthus sociatus and (5) area with high coverage of Palythoa caribaeroum. Obtained data suggest that the studied area has been damaged by tourism activities. Furthermore, observed differences in algal communities may be a good indicator of ecosystem health of Pirangi reefs

Ecologia humana e manejo participativo da pesca do búzio Anomalocardia brasiliana (Gmelin, 1791) (Bivalvia: Veneridae) na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão (RN)

Coastal and marine protected areas are created to protect habitat, avoid biodiversity loss, and to help maintain viable fisheries. However, most of these areas in tropical countries occurs in impoverished regions and directly affect the livelihood and survival of coastal communities which directly depend on fisheries and shellfisheries. Therefore, socioeconomic and conservation goals overlap. In this context, fishers should have a central place in resource management. They are critical resource users and their behavior directly affects the system. Shellfish resources are important sources of food, employment and income to fishing communities in Latin America. But despite its widespread use for food and income, there is an urgent need of more research on shellfish management. This research discusses the artisanal fisheries of Venus clam (Anomalocardia brasiliana) (Gmelin, 1791) (Bivalvia: Veneridae) in Brazil, and points out strategies to improve the system. Venus clam is a small and commonly exploited species for food and income on the Brazilian coast. This research was carried out at Ponta do Tubarão Sustainable Development Reserve (Brazilian Northeast coast), where there was no information available about who harvest, where or how much Venus clam has been harvested, despite this resource being exploited for generations. Clam fishery follows the pattern of socio-economic invisibility that general clam exploitation has in Brazil. Methods used were interviews, participatory monitoring and focal follow observation from January 2010 to May 2011. Results include: (a) the identification of shell fishers, (b) how harvest and meat processing are performed (mollusk beds, time spent, gross and net production), (c) the analisis of shell fisher income and their economic sustentability, and (d) the involvement of shell fisher families in data gathering and analyses for the first time. Based on the acquired knowledge, we propose a new institutional arrangement for clam fishery including co-management, fisheries agreement, compensatory arrangements and improvements for the Venus clam value chain such as the establishment of a minimum price for clam meat. This research also includes two other results: a general description for Venus clam harvesting in the Brazilian Northeast coast and a specific discussion about co-management of Venus clam in Brazil. The first one was possible through the meeting of several shell fisherwomen from other states during activities promoted by People of the Tides (PoT) project. PoT was an international initiative aiming to develop coastal communities that depend on mollusk for their livelihood. The second one is a comparison between PoT and Venus clam management at Pirajubaé Marine Extractive Reserve (Santa Catarina). It evaluates the success and failures of these only two initiatives involving co-management of A. brasiliana in Brazil

Permian bivalves of the Taciba Formation, Itarare group, Parana basin, and their biostratigraphic significance

A small and poorly diversified bivalve fauna from Taciba Formation, Itarare Group, Parana Basin (State of Santa Catarina, Mafra Municipality), is described in this paper for the first time, based on new findings. The fauna is recorded in a 30 cm thick interval of fine sandstone locally at the top of Taciba Formation, in the Butia quarry. The studied fossil-bearing sand-stone bed is a marine intercalation recording a brief eustatic rise in sea-level, probably following glacier retreat and climate amelioration at the end of a broad glacial scenario. The fauna is mainly dominated by productid brachiopods, which are not described here, and rare mollusk shells (bivalves and gastropods). Two bivalve species were identified: Myonia argentinensis (Harrington, 1955), and Aviculopecten multiscalptus (Thomas, 1928). The presence of Myonia argentinensis is note-worthy since this species is also present in the Baitaca assemblage found in marine siltstones (Baitaca assemblage) of the Rio do Sul Formation, cropping out at the Teixeira Soares region, Parana State. This species is also recorded in the bivalve fauna from the Bonete Formation, Pillahinco Group, Sauce Grande Basin, Buenos Aires Province, in Argentina. Hence, the marine bivalves of the Taciba Formation are associated with the transgressive event that characterizes the Eurydesma fauna, indicating a Late Asselian-Sakmarian age for the bivalve fauna. Presence of the Myonia argentinensis megadesmid species reinforces the Gondwanic nature of the studied fauna.
