The phenomenon of homing by salmonid fishes to natal sites for breeding is well established, but the chemicals in rivers that they learn as juveniles and identify as adults are not fully determined. Dissolved free amino acid (DFAA) profiles have been hypothesized to allow salmonids to distinguish their natal river from others nearby. To evaluate this hypothesis, we sampled DFAAs in spring and autumn (when juveniles learn and adults return, respectively) from 3 rivers in New England, USA, that support the landlocked Atlantic Salmon, Salmo salar Linnaeus, 1758. We used 3 approaches to determine the level of consistency between seasons and difference between rivers that would be needed for DFAA to support imprinting and subsequent homing for reproduction: hierarchical cluster analysis, statistical difference tests, and equivalence tests. DFAAs were not detected in the water column of the study rivers, but sediment porewater samples yielded DFAAs at measurable concentrations. Hierarchical cluster analysis, difference testing, and equivalence testing all indicated that some combinations of sediment porewater DFAA concentrations differed among rivers and were similar between spring and autumn within a river. Specifically, equivalence tests revealed subsets of sediment porewater DFAAs that were seasonally equivalent within each river, and none of the seasonally equivalent DFAAs were common among all 3 rivers (i.e., each river had a unique DFAA profile). However, exceptions detected in the cluster analysis and equivalence testing raise questions regarding the extent to which DFAAs might be sufficient for salmon imprinting and homing. Thus, DFAAs may fulfill some of the hypothesized prerequisites as salmon imprinting and homing odor cues, but our lack of understanding of salmon discriminatory abilities and limited DFAA data preclude definitive conclusions about the sufficiency of DFAAs alone as homing cues.

Environmental DNA (eDNA) is a powerful conservation tool that has made significant advancements in the past decade. Since its initial application in 2008 to detect invasive tadpoles, eDNA has become popular for finding rare and invasive species that are otherwise difficult to detect through traditional field sampling methods. This study sought to determine a detectable range of eDNA for an aggressively invasive aquatic plant species, Hydrilla verticillata (L. f.) Royle, as well as to understand how stream discharge affects eDNA detection distance. To do so, we surveyed downstream of a large reservoir, which is separated from its distributary by a dam. Hydrilla verticillata is present in the reservoir but absent in the distributary. We used correlation analysis to understand the relationship between transportation distance and detection. We also built upon a model developed by Pont et al. (2018) to assess the relationships between stream discharge and eDNA detection distance, as well as to compare this relationship for our plant-based eDNA study with previous animal-based studies. By utilizing this natural system and surveying at different points downstream of the known population, this study detected H. verticillata eDNA nearly 5 km from the source population. This study, which is the 1st known instance of correlating plant eDNA to animal eDNA detection ranges, suggests the genetic material of both kingdoms are similarly detectable in flowing freshwaters and supports other studies that suggest discharge is a strong predictor of the detectable distance of eDNA.
