PLoS 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

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 ...

Gravel washing as a lacustrine spawning habitat restoration method for smallmouth bass
Aquatic Living ResourcesSmallmouth bass (Micropterus dolomieu) spawn on gravel and cobble in the littoral zone of lakes that may become degraded by the presence of fine sediments and decomposing organic matter.

Ecosphere, 2021 Dam‐mediated biological invasions are a serious problem all over the world. Once established in reservoirs, the invasive species have catastrophic impacts on the river ecosystems downstream, and thus, rapid monitoring of invasive species is an urgent ...

Climate change simulations predict altered biotic response in a thermally heterogeneous stream system. [PDF]
PLoS ONE, 2014 Climate change is predicted to increase water temperatures in many lotic systems, but little is known about how changes in air temperature affect lotic systems heavily influenced by groundwater.

A framework for investigating fish population density responses to habitat fragmentation
Oikos, Volume 2026, Issue 11, November 2026.Globally, fish populations that rely on rivers are being fragmented by in‐stream barriers, but it is unclear how pervasive any negative population responses to fragmentation are. We developed a modeling framework for estimating density responses of fishes upstream and downstream of in‐stream barriers and applied it to learn how low‐head dams have ...

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 ...

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.
