Effects of Ligula intestinalis on habitat use, predation risk and catchability in European minnows

JOURNAL OF FISH BIOLOGY, Issue 4 2001
J. Museth
The frequency of infection with Ligula intestinalis (Cestoda) in European minnow Phoxinus phoxinus, in a subalpine lake in Eastern Norway, did not differ between vegetated shoreline, exposed shoreline and non-vegetated localities >50 m from the shoreline. There was no difference in the vertical distribution of infected and uninfected individuals. The frequency of infection was higher among minnows in brown trout Salmo trutta stomachs than among those obtained by gillnets and minnow traps, suggesting that brown trout selectively preyed on infected minnows. Prevalence of infection decreased with increasing fish size, probably due to selective mortality among parasitized individuals. Within a given length-class, minnows captured by different sections of multi-mesh gillnets showed a significant increase in the frequency of infection with increasing mesh-size. Apparently, parasitized individuals had a higher catchability in gillnets due to increased girth caused by the plerocercoid in the body cavity. This may partly explain why the observed prevalence of infection was several times higher among minnows captured by gillnets than by minnow traps. [source]

Functional outcome and health-related quality of life 10 years after moderate-to-severe traumatic brain injury

ACTA NEUROLOGICA SCANDINAVICA, Issue 1 2009
N. Andelic
Objectives,,, To describe the functional outcome and health-related quality of life (HRQL) 10 years after moderate-to-severe traumatic brain injury (TBI). Material and methods,,, A retrospective, population-based study of 62 survivors of working-age with moderate-to-severe TBI injured in 1995/1996, and hospitalized at the Trauma Referral Center in Eastern Norway. Functional status was measured by the Glasgow Outcome Scale-Extended (GOS-E). HRQL was assessed by the SF-36 questionnaire. Results,,, The mean current-age was 40.8 years. The frequency of epilepsy was 19% and the depression rate 31%. A majority had good recovery (48%) or moderate disability (44%). Employment rate was 58%. Functional and employment status were associated with initial injury severity in contrast to HRQL. Study patients had significantly lower scores in all SF-36 dimensions when compared with the general Norwegian population. Conclusion,,, At 10-years follow-up, our study population is still in their most productive years and affected domains should be considered in long-term follow-up and intervention programs. [source]

The new neighbour: Experiences of living next door to people suffering from long-term mental illness

INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 1 2003
Arild Granerud
ABSTRACT The transition from hospital to community care for people with long-term mental illness is of growing concern. The aim of the present study was to illuminate if and how people with long-term mental illness have affected their neighbourhood after re-establishing themselves in apartments of their own. Nineteen neighbours of group homes for people with long-term mental illness, in seven different communities in eastern Norway, have been interviewed. The grounded theory procedures as well as the constant comparative method were employed to analyse the findings. From the data, one main category was identified: the need for information. [source]

Masting and trophic cascades: interplay between rowan trees, apple fruit moth, and their parasitoid in southern Norway

OIKOS, Issue 3 2004
Akiko Satake
We analyzed berry production in rowan, Sorbus aucuparia L., in southern Norway and examined the ramifying effects of rowan masting on the dynamics of the dominant seed predator and its parasitoid. The apple fruit moth, Argyresthia conjugella Zeller, is a pre-dispersal seed predator of rowan. The larva of the apple fruit moth rely on rowan berries, which in turn is attacked by the parasitoid wasp, Microgaster politus Marsh. We found classic masting in rowan: berry production varied across years (the mean coefficient of variation=1.02) and was spatially synchronized at large scale (the averaged correlation coefficient=0.67). Berry production represented a two-year cycle in western but a three-year cycle in eastern Norway. The abundance of the moth and the parasitoid also varied across years and were spatially synchronized. The degree of spatial synchrony decreased and cyclicity became obscure with increasing trophic level. We attempted to assess two different components to the predator satiation, functional and numerical satiations, based on a simple population dynamics model. The observed pattern of seed predation testified that both of functional and numerical satiations were at work in this system. In a comparison at different locations, rowan trees with more variable berry production were more effective in reducing losses to the seed predator. The parasitoids also seemed to experience satiation through the fluctuation in their host abundance. These results show that rowan masting has an adaptive foundation, which impacts the dynamics of higher trophic levels. [source]
