Abiotic and biotic factors determine success or failure of individual organisms, populations and species. The early life stages are often the most vulnerable to heavy mortality due to environmental conditions. The deer ked (Lipoptena cervi Linnaeus, 1758) is an invasive insect ectoparasite of cervids that spends an important period of the life cycle outside host as immobile pupa. During winter, dark-coloured pupae drop off the host onto the snow, where they are exposed to environmental temperature variation and predation as long as the new snowfall provides shelter against these mortality factors. The other possible option is to passively sink into the snow, which is aided by morphology of pupae. Here, we experimentally studied passive snow sinking capacity of pupae of L. cervi. We show that pupae have a notable passive snow sinking capacity, which is the most likely explained by pupal morphology enabling solar energy absorption and pupal weight. The present results can be used when planning future studies and when evaluating possible predation risk and overall survival of this invasive ectoparasite species in changing environmental conditions. ...

Warming temperatures and ectoparasitic sea lice impair internal organs in juvenile Atlantic salmon Medcalf, Kate E.; Hutchings, Jeffrey A.; Fast, Mark D.; Kuparinen, Anna; Godwin, Sean C. (Inter-Research, 2021)As a consequence of climate change and open net-pen salmon farming, wild Atlantic salmon Salmo salar are increasingly likely to encounter elevated temperatures and parasite abundances during their early marine migration. ...

Effects of predation pressure and resource use on morphological divergence in omnivorous prey fish Scharnweber, Kristin; Watanabe, Kozo; Syväranta, Jari; Wanke, Thomas; Monaghan, Michael T; Mehner, Thomas (BioMed Central, 2013)Background. Body shape is one of the most variable traits of organisms and responds to a broad array of local selective forces. In freshwater fish, divergent body shapes within single species have been repeatedly observed ...
