Body size adaptions under climate change: Zooplankton community more important than temperature or food abundance in model of a zooplanktivorous fish
Ljungström, Anna Jeja Gabriella; Claireaux, Marion; Fiksen, Øyvind; Jørgensen, Christian (Journal article; Peer reviewed, 2020)One of the most well-studied biogeographic patterns is increasing body size with latitude, and recent body size declines in marine and terrestrial organisms have received growing attention. Spatial and temporal variation ... -
Degrees of change: between and within population variation in thermal reaction norms of phenology in a viviparous lizard
Cunningham, George D.; While, Geoffrey M.; Olsson, Mats; Ljungström, Anna Jeja Gabriella; Wapstra, Erik (Journal article; Peer reviewed, 2020)As the earth warms, populations will be faced with novel environments to which they may not be adapted. In the short term, populations can be buffered against the negative effects, or maximize the beneficial effects, of ... -
Parent-offspring conflict over reproductive timing: ecological dynamics far away and at other times may explain spawning variability in Pacific herring
Ljungström, Anna Jeja Gabriella; Francis, Tessa; Mangel, Marc; Jørgensen, Christian (Peer reviewed; Journal article, 2019)Timing of reproduction may be of crucial importance for fitness, particularly in environments that vary seasonally in food availability or predation risk. However, for animals with spatially separated feeding and breeding ... -
Planktivorous fish and environmental change: using mechanistic modelling to explore the underpinnings and general validity of expected responses
Ljungström, Anna Jeja Gabriella (Doctoral thesis, 2020-03-13)The living conditions of marine and terrestrial organisms are currently changing at a rapid pace due to human activities. To predict how this will affect them, and hence to develop appropriate management and conservation ... -
Poleward distribution of mesopelagic fishes is constrained by seasonality in light
Langbehn, Tom; Aksnes, Dag Lorents; Kaartvedt, Stein; Fiksen, Øyvind; Ljungström, Anna Jeja Gabriella; Jørgensen, Christian (Journal article; Peer reviewed, 2022)Aim: Mesopelagic fishes have a near-global distribution in the upper 1,000 m from tropical to sub-Arctic oceans across temperature regimes. Yet, their abundance decreases poleward and viable populations seem excluded from ... -
Quantitative genetics of breeding coloration in sand lizards; genic capture unlikely to maintain additive genetic variance
Lindsay, Willow R.; Bererhi, Badreddine; Ljungström, Anna Jeja Gabriella; Wapstra, Erik; Olsson, Mats (Journal article; Peer reviewed, 2023)Sexual selection on fitness-determining traits should theoretically erode genetic variance and lead to low heritability. However, many sexually selected traits maintain significant phenotypic and additive genetic variance, ...
