Mate fidelity and coloniality in waterbirds: a comparative analysis

1998

Increased opportunities for information are one potential benefit of sociality. We apply this idea to the advantages of colonial breeding in bird species that are typically monogamous within a breeding season but often form new pair-bonds in subsequent seasons. Individuals may benefit from nesting in colonies at high density by identifying good-quality potential alternative mates among their neighbours. The opportunities for finding a better mating option are likely to increase with colony size and density. We tested this prediction with a comparative analysis of the association between mate fidelity and coloniality in waterbirds (wading birds and seabirds), where there is wide variation in…

Helminth Communities in Audouin's Gulls, Larus audouinii from Chafarinas Islands (Western Mediterranean)

1999

A survey of intestinal helminth communities of Audouin's s gulls Larus audouinii, from their breeding colonies in Chafarinas Islands, western Mediterranean, Spain was conducted to determine the abundance and species diversity of intestinal parasites of these birds. The sample of 58 gulls harbored intestinal helminth infracommunities composed of species that are gull generalists, including the digeneans Cardiocephalus longicollis, Knipowitschiatrema nicolai, Condylocotyla pilodora, and Aporchis massiliensis, and the cestode Tetrabothrius cylindraceus. Two nematodes are waterfowl generalists (Cosmocephalus obvelatus and Paracuaria adunca), whereas the digenean Acanthotrema armata is an Audoui…

Pesticide residues in some Baltic animals - a review of selected literature

1975

ABSTRACT During the last few years, considerable efforts have been devoted to the tracing of halogenated hydrocarbons, particularly DDT and PCB, and of mercury in Baltic animals. These investigations have already produced some important generalizations, which may be summarized as follows: (1) The concentrations of halogenated hydrocarbons and mercury in the tissues of Baltic animals are in general higher than those found in the corresponding species on the west coast of Sweden and in the Norwegian waters. (2) The highest levels of DDT compounds seem to occur in the animals of the southern Baltic and the Sound (oresund). (3) The highest contents of methylmercury in the Baltic fish occur in c…

Sources of variation in survival and breeding site fidelity in three species of European ducks

2002

Summary 1  We used long-term capture–recapture–recovery data and a modelling approach developed by Burnham (1993) to test a priori predictions about sources of variation in annual survival rates and fidelity within a population of individually marked females in three species of European ducks from a breeding ground study site in Latvia. 2  True annual survival was higher for diving ducks (tufted duck 0·72, common pochard 0·65) and lower for northern shoveler (0·52). Survival of female diving ducks was positively correlated with mean winter temperatures at Western European wintering areas, the relationship being much stronger for pochard. 3  We present the first unbiased estimates of breedin…

Origins and originality : Authenticity in the media representation of Julie Fowlis

2018

This article examines the ways in which Scottish Gaelic singer Julie Fowlis is constructed ‘authentic’ in the media. Two narratives that I call ‘narrative of origins’ and ‘narrative of professionalism’ construct her authenticity as a representative of the folk music scene. Fowlis represents the new Gaelic speaker, but is presented in terms of stereotypical imagery connected to Scotland, which portrays tradition as stagnant, quaint and in need of preservation. However, she is also presented as a professional artist, remaking and reinterpreting the tradition of a living culture that she represents. Thus, here authenticity ascribed on the artist is viewed as a cultural memory device, built on …

Yksilöllisen oppimisen mallin soveltuvuus yläkoulun 7. luokan lajintuntemuksen opetukseen

2017

Suomalaisen koulujärjestelmän uudistuksia ohjaamaan astuivat elokuussa 2016 voimaan uudet valtakunnallisen perusopetuksen opetussuunnitelmien perusteet, jotka korostavat konstruktivistista oppimiskäsitystä ja tulevaisuuden osaamiseen valmentavia tietoja ja taitoja. Biologian opetuksen tehtävänä on kartuttaa oppilaan luonnontuntemusta yhteisöllisiä ja toiminnallisia opetusmenetelmiä hyödyntäen. Sen tulee myös ohjata oppilaiden luonnontieteellisen ajattelun kehitystä vuorovaikutuksessa muiden oppilaiden kanssa. Tämän tutkimuksen tavoitteena oli tutkia matemaatikko Pekka Peuran kehittelemän yksilöllisen oppimisen mallin soveltuvuutta lajintuntemuksen opetukseen biologian oppiaineessa yläkoulun…
