    Trychophrya intermedia on the gills of rainbow trout acclimating to low ambient pH (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 48 (1996), S. 0 
    Details
    ISSN: 1095-8649

    Topics: Biology
    Notes: Rainbow trout under low pH conditions acquire heavy infections with Trychophrya intermedia, not secondary to gill damage, which suggests that the parasite may have a primary effect on gill function in fish Under acid Conditions.

    Plasma cortisol and 17β-oestradiol levels in roach exposed to acute and chronic stress (1999)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 54 (1999), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Plasma cortisol levels were measured as an indicator of physiological stress in roach subjected to brief handling, or to a 14-day period of confinement, and in undisturbed control fish, during winter (water temperature 5° C) and summer (16° C), at which time plasma 17 β-oestradiol levels were also determined. Cortisol levels in undisturbed roach were low (mean 8·1 ng ml−1 at 5° C; 1·4 ng ml−1 at 16° C) and both handling and handling+confinement elevated blood cortisol levels significantly to 400 and 140 ng ml−1, respectively (at 5° C) and 700 and 600 ng ml−1, respectively (at 16) C). Blood cortisol levels had almost returned to baseline within 4 h following handling alone but in fish subjected to handling and prolonged confinement cortisol levels remained elevated for up to 168 h. Differences in baseline and poststress levels of cortisol, and in the rate of recovery from acute stress, were observed at the two different temperatures and the possible factors underlying these differences are discussed. Circulating levels of 17 β-oestradiol were reduced significantly within 24 h of exposure to either acute handling or chronic confinement indicating that the reproductive endocrine system in roach is sensitive to disruption by stressors.

    Invertebrates in salt lakes of the Bolivian Altiplano (1995)
    Springer
    International journal of salt lake research 4 (1995), S. 65-77 
    Details
    ISSN: 1573-8590
    Keywords: invertebrates ; salt lakes ; Altiplano ; Bolivia

    Topics: Biology , Geography
    Notes: Abstract Based upon a short reconnaissance (March 1991), the chemicalnature and principal invertebrate fauna of seven saline lakes on the Altiplano of southern Bolivia are discussed (Lago de Uru-uru, Pastos Grandes, Lago Ramiditas, Lago Hedionda, Lago Cañapa, Laguna Colorado, pool at L. Colorado). Salinities ranged between 4.4 and 156 g L−1. The fauna was depauperate. Except at the lowest salinities (〈5 gL−1), rotifers were absent. At high salinities (〉≈50 g L−1), onlyArtemia, Boeckella poopoensis, ephydrids and a dolichopodid were present.
