North-temperate fishes are subject to significant changes in abiotic and biotic conditions across seasons, which are likely reflected in temporal differences in energy dynamics, reproductive investment, and diet. This study explores seasonal changes in body lipid content, female reproductive investment (GSI), body condition (Fulton’s K), and diet in brook sticklebacks (Culaea inconstans) in Western New York. I expected body lipid content and body condition would decline during the breeding season reflecting energy expenditure for reproduction, and these parameters would increase in the summer and fall prior to the onset of winter. Based on previous studies, I also expected …
