It’s complicated: Heterogeneous patterns of genetic structure in five fish species from a fragmented river suggest multiple processes can drive differentiation

Evolutionary Applications, 2021
Fragmentation of river systems by dams can have substantial genetic impacts on fish populations. However, genetic structure can exist naturally at small scales through processes other than isolation by physical barriers.

A NOVEL NON-LETHAL LAPAROSCOPIC APPROACH TO DETECT INTERSEX (TESTICULAR OOCYTES) IN LARGEMOUTH BASS (MICROPTERUS SALMOIDES) AND SMALLMOUTH BASS (MICROPTERUS DOLOMIEU) [PDF]

, 2016
The appearance of testicular oocytes (TO) in wild fish populations has received considerable attention in the scientific literature and public media. Current methods to quantify TO are lethal; instead, a non-lethal alternative was examined.

No fish no problem: Diet plasticity as an invasion driver in Japanese smallmouth bass

Global Ecology and Conservation
Diet plasticity of invasive apex predatory fish is thought to potentially amplify their negative effects on native species. Smallmouth bass (Micropterus dolomieu), an invasive sport fish introduced globally, are a known fish predator that have caused ...

Hyperpigmented melanistic skin lesions of smallmouth bass Micropterus dolomieu from the Chesapeake Bay watershed [PDF]

Diseases of Aquatic Organisms, 2020
Hyperpigmented melanistic skin lesions (HPMLs) of smallmouth bassMicropterus dolomieuare observed in the Potomac and Susquehanna rivers, Chesapeake Bay watershed, USA. Routine, nonlethal population surveys were conducted at 8 sites on the mainstem Susquehanna River and 9 on the Juniata River, a tributary of the Susquehanna River, between 2012 and 2018,

A comprehensive multi-state conditional occupancy model for evaluating interactions of non-native and native species

Frontiers in Ecology and Evolution, 2023
A major challenge in ecology is disentangling interactions of non-native, potentially invasive species on native species. Conditional two-species occupancy models examine the effects of dominant species (e.g., non-native) on subordinate species (e.g ...

How Tough a Passage? Nonnative Fish Entrainment Survivability at a Major Dam in the Western USA

River Research and Applications, Volume 42, Issue 9, Page 1970-1976, November 2026.
ABSTRACT The Colorado River downstream of Glen Canyon Dam (GCD) in the southwest USA demonstrates anthropogenic modification including altered flow and temperature regimes and established nonnative species in upstream reservoirs. Water overallocation and megadrought are contributing to new potential invasion pathways for nonnative fishes through dam ...

An Investigation of the Stomach Contents of Micropterus Dolomieu [PDF]

, 1938
It was the purpose of this study to scientifically analyze the stomach contents of Micropterus dolomieu. The study was based upon 168 stomachs taken from various sized fish caught by hook and line from the streams of Northern ...

Decision support for aquatic restoration based on species‐specific responses to disturbance

Ecology and Evolution, 2022
Disturbances to aquatic habitats are not uniformly distributed within the Great Lakes and acute effects can be strongest in nearshore areas where both landscape and within lake effects can have strong influence.

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

Biological Reviews, Volume 101, Issue 5, Page 2337-2358, October 2026.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.
