Fish and Zooplankton Community Responses to the Cessation of Long-Term Invasive Eurasian Watermilfoil (Myriophyllum spicatum) Chemical Treatments in a North-Temperate, USA Lake

open access: yesFishes, 2022
2,4-Dichlorophenoxyacetic acid (2,4-D) is commonly used to control invasive aquatic macrophytes, including Eurasian watermilfoil (Myriophyllum spicatum) (EWM). Potential influences of 2,4-D on non-target organisms are poorly understood; however, research

Go big or … don't? A field-based diet evaluation of freshwater piscivore and prey fish size relationships. [PDF]

open access: yesPLoS ONE, 2018
Body size governs predator-prey interactions, which in turn structure populations, communities, and food webs. Understanding predator-prey size relationships is valuable from a theoretical perspective, in basic research, and for management applications ...

Invasive smallmouth bass (Micropterus dolomieu): history, impacts, and control [PDF]

open access: yesManagement of Biological Invasions, 2013
In this review, we (i) describe smallmouth bass (Micropterus dolomieu Lacepede, 1802) invasions past, present, and future; (ii) summarize the impact that this species can have on native communities; and (iii) describe and discuss various options for control. M. dolomieu are invasive throughout much of the United States, southern portions of Canada, and

Predicting sport fish mercury contamination in heavily managed reservoirs: Implications for human and ecological health.

open access: yesPLoS ONE, 2023
Mercury (Hg) is a concerning contaminant due to its widespread distribution and tendency to accumulate to harmful concentrations in biota. We used a machine learning approach called random forest (RF) to test for different predictors of Hg concentrations

Application of a Lipopolysaccharide (LPS)-Stimulated Mitogenesis Assay in Smallmouth Bass (Micropterus dolomieu) to Augment Wild Fish Health Studies

open access: yesFishes, 2023
The utility of a functional immune assay for smallmouth bass (Micropterus dolomieu) lymphocyte mitogenesis was evaluated. Wild populations in the Potomac River have faced disease and mortality with immunosuppression from exposure to chemical contaminants

Endocrine and scavenging cell functions of a juvenile fish heart atrium: Fine structure aspects and translating conjectures

open access: yesTranslational Research in Anatomy, 2023
Background: The atrium of the juvenile teleost, smallmouth bass, Micropterus dolomieu Lacépède showed a pigmented endocardium. Our goal was to use fine structure to survey this fish heart tissues and verify the content responsible for this shrouding and ...
