The bittern, Botaurus stellaris (L.), is a Red Data list species in the UK with currently approximately 30 breeding males restricted to a few wet reedbeds, the majority of which are located in the East Anglian region of England. Although having a div...

Is water temperature an adequate predictor of recruitment success in cyprinid fish populations in lowland rivers? (2003)
Journal Article
Nunn, A., Cowx, I., Frear, P., & Harvey, J. (2003). Is water temperature an adequate predictor of recruitment success in cyprinid fish populations in lowland rivers?. Freshwater biology, 48(4), 579-588. https://doi.org/10.1046/j.1365-2427.2003.01033.x

1. Higher than average ambient water temperature in the first year of life may be responsible for strong cohorts of adult cyprinid fish. Whilst temperature explains much of the variation in year-class strength (YCS), however, it is not the only influ...

Recruitment patterns of six species of cyprinid fishes in the lower River Trent, England (2002)
Journal Article
Nunn, A. D., Cowx, I. G., & Harvey, J. P. (2002). Recruitment patterns of six species of cyprinid fishes in the lower River Trent, England. Ecology of freshwater fish, 11(2), 74-84. https://doi.org/10.1034/j.1600-0633.2002.t01-1-00001.x

Fisheries data were collected for six species of 0-group cyprinid fishes from eight sites in the lower reaches of the River Trent, England, between May and October 1999 inclusive, using a micromesh seine net. Recruitment and growth patterns were obse... Read More about Recruitment patterns of six species of cyprinid fishes in the lower River Trent, England.
