Upstream effects of a reservoir on fish assemblages 45 years following impoundment.

abstract：:This study investigated whether a putative shift in climate regime in the North Atlantic in the 1990s coincided with changes in the growth and recruitment of roach Rutilus rutilus in the north-east of England. The relationships between R. rutilus growth and recruitment and the environment were significantly different ...
