Basal resources form the foundation of aquatic food webs, transferring energy from primary producers to higher trophic levels. Understanding how these resource pathways change over space and time to support consumers improves our understanding of food-web function. However, resource use in wetland habitats can be complex, given a wide diversity of available basal sources and environmental conditions. We investigated how differences in geomorphology across eight wetland sites influence the relative contribution of basal resources, including phytoplankton, periphyton, macrophytes, and detritus, to the energetic pathways supporting young-of-year (YOY) Northern Pike (Esox lucius) an important wetland predator. Given their generalist feeding behavior, known habitat use over ontogeny, and role as apex predators, YOY Northern Pike serve as an ideal organism for evaluating how basal resource contributions differ across wetland types. Eight nursery sites were selected: seven in the Thousand Islands region of the Upper St. Lawrence River and one in Cranberry Lake, located in Adirondack Park (both New York, USA). These sites span a gradient of wetland geomorphic types (protected and open coastal embayment, drowned river mouth, and palustrine) and aquatic plant invasion impact. We used stable isotope analysis of δ¹³C and δ¹⁵N and Bayesian mixing models to identify energetic pathways providing dominant support for YOY Northern Pike. Preliminary results suggest variation in the isotopic composition of basal resources across wetland types, with resources in coastal embayments being more enriched in ¹³C compared to those of drowned river mouth wetlands (mean ± SD δ¹³C = −20.8 ± 7.39‰ vs. −28.6 ± 2.96‰). Additionally, YOY Northern Pike trophic niche size was higher in drowned river mouth wetlands when compared to coastal embayments (total area = 9.6 vs 3.2), suggesting a diversified use of resources within these habitats. Investigating basal resource variation among nursery habitats provides insight into how energy moves through wetland food webs, how trophic pathways differ among habitat types, and how basal production ultimately supports higher trophic levels. Additionally, incorporating YOY Northern Pike introduces a tertiary consumer into nursery food-web analyses, linking basal resources to the energetic support of a top predator during a critical early life stage.
