Interactive effects of arrival date, territory quality and male polyterritorial behaviour on the mating system of the sedge warbler Acrocephalus schoenobaenus – a path analysis

Wojciech Bielański, Adam Ćmiel & Tadeusz Zając
Classical models predict that male fitness is based on resources monopolized and invested in reproduction, and/or on individual quality providing offspring with sexually attractive traits or viable genes. However, these factors are frequently correlated, making their relative influence on male fitness difficult to describe and quantify. We analysed the relative influence of the main features of the sedge warbler's (Acrocephalus schoenobaenus) breeding system, i.e. age, arrival date, territory quality, male sexual activity (song and polyterritorial...

Cross-latitude behaviours in an adult damselfly Calopteryx splendens

Maria J. Golab
The study organism was the temperate damselfly Calopteryx splendens. The behavioural expressions along 3 latitudinal regions was studied and a body size was measured. Activity (patrol flights and male chases) was the only behaviour feature positively associated with latitudinal gradient. Courtship effort was highest in the central region, whereas boldness (immobility, time to return and first move) values were highest in the north but did not differ between central and south. In the southern region,...

Data for 'Phenological shifts in a warming world affect physiology and life history in a damselfly'

Mateusz Raczyński, Robby Stoks, Frank Johansson, Kamil Bartoń & Szymon Sniegula
In this analysis we studied, in laboratory conditions, the impact of warming and hatching dates on key life history and physiological traits in a cannibalistic damselfly, Ischnura elegans. Larvae were reared in groups from hatching to emergence through one or two growth seasons, depending on the voltinism. Larvae were equally divided by hatching dates (early and late) and temperature treatment (current and warming). Early and late hatched groups were not mixed. This data set includes:survival...
