Hydrological seasonality is a major driver of ecosystem metabolism in tropical nonwadeable rivers

open access: yesLimnology and Oceanography, EarlyView.
Abstract Studies of annual patterns of ecosystem metabolism in rivers have primarily been conducted in temperate ecosystems, and little is known about metabolic regimes of tropical rivers. We estimated ecosystem metabolism in four nonwadeable rivers in southern México that varied in size and the extent of human disturbance.

Variable phenology but consistent loss of ice cover on 1213 Minnesota lakes

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Lake ice cover is declining globally with important implications for lake ecosystems. Ice loss studies often rely on small numbers of lakes with long‐term data. We analyzed variation and trends in ice cover phenology from 1213 lakes over 74 yr (1949–2022) in Minnesota (USA), during which ice cover duration declined at a rate of 2 d per decade (

Revisiting k: Time‐varying stream litter breakdown rates

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Litter decomposition is usually modeled with the negative exponential model, which assumes constant proportional mass loss. We assessed this assumption and its interpretive consequences using 145 stream litter mass loss time series and process‐based simulations.

High-resolution mapping of reciprocal translocation breakpoints using long-read sequencing

open access: yesMethodsX, 2019
Long-read nanopore sequencing enables direct high-resolution breakpoint mapping on balanced carriers of reciprocal translocation. The mean sequencing depth on the translocated chromosomes to achieve accurate mapping of breakpoints ranged from 2.5-fold to

Identifying conditions associated with outliers produced by three different chlorophyll fluorometers: A comparison of instrumentation and development of correction formulae

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Measurements of chlorophyll concentration reported by fluorometers (fChl) are used in environmental research and monitoring, as inputs to models, and in the interpretation of remote sensing data. Researchers and managers benefit from understanding how to interpret and ensure the accuracy of fChl data collected by in situ fluorometers. Although
