Lakes are classified by thermal mixing regimes, with shallow waterbodies historically categorized as continuously mixing systems. Yet, recent studies demonstrate extended summertime stratification in ponds, underscoring the need to reassess thermal classifications for shallow waterbodies. In this study, we examined the summertime thermal dynamics of 34 ponds...
Co-occurrence models fail to infer underlying patterns of avoidance and aggregation when closure is violated
Robert Charles Lonsinger
2022, Ecology and Evolution (12)
Advances in multi-species monitoring have prompted an increase in the use of multi-species occupancy analyses to assess patterns of co-occurrence among species, even when data were collected at scales likely violating the assumption that sites were closed to changes in the occupancy state for...
Failure to achieve recommended environmental flows coincides with declining fish populations: Long-term trends in regulated and unregulated rivers

2022, Freshwater Biology (67) 1631-1643
Dams can be operated to mimic components of the natural flow regime to minimise impacts on downstream ecosystems. However, infrastructure, societal needs, water management, and catchment runoff constrain which and when flow regime attributes can be mimicked.We compared fish assemblage responses, including native and non-native species, over 2 decades...
Exposure and effects of bioaccumulative contaminants of emerging concern in tree swallows nesting across the Laurentian Great Lakes
Christine M. Custer, Thomas W. Custer, Paul M. Dummer
2022, Report, Contaminants of emerging concern in the Great Lakes: Science to inform management practices for protecting the health and integrity of wildlife populations from adverse effects
Contaminants of emerging concern (CECs) are a loosely defined group of chemicals whose wide-spread usage or presence in the environment has occurred more recently or for which there has been relatively little research done until recently. Many of these CECs are not currently regulated. The National Toxicology Program within the...

2022, Open-File Report 2022-1041
The 2012 Little Bear Fire resulted in substantial loss of vegetation in the Eagle Creek Basin, south-central New Mexico, which has been expected to cause a variety of hydrologic responses that could influence geomorphic change to North Fork Eagle Creek. To monitor geomorphic change, surveys of a downstream study reach...

Towards continuous streamflow monitoring with time-lapse cameras and deep learning
Amrita Gupta, Tony Chang, Jeffrey Walker, Benjamin Letcher
2022, Conference Paper, COMPASS '22: ACM SIGCAS/SIGCHI Conference on Computing and Sustainable Societies (COMPASS)
Effective water resources management depends on monitoring the volume of water flowing through streams and rivers, but collecting continuous discharge measurements using traditional streamflow gauges is prohibitively expensive. Time-lapse cameras offer a lowcost option for streamflow monitoring, but training models for predicting streamflow directly from images requires streamflow data to use as labels, which are often...
Climate change risks to global forest health: Emergence of unexpected events of elevated tree mortality worldwide
Henrik Hartmann, Ana Bastos, Adrian Das, Adriane Esquivel-Muelbert, William M Hammond, Jordi Martínez-Vilalta, Nate G. McDowell, Jennifer S. Powers, Thomas A. M. Pugh, Katinka X. Ruthrof, Craig D. Allen
2022, Annual Review of Plant Biology (73) 673-702
Recent observations of elevated tree mortality following climate extremes, like heat and drought, raise concerns about climate change risks to global forest health. We currently lack both sufficient data and understanding to identify whether these observations represent a global trend towards increasing tree mortality. Here, we document events of sudden...
Ventilation systems in wetland plant species

2022, Diversity (14)
Molecular oxygen and carbon dioxide may be limited for aquatic plants, but they have various mechanisms for acquiring these gases from the atmosphere, soil, or metabolic processes. The most common adaptations of aquatic plants involve various aerenchymatic structures, which occur in various organs, and enable the throughflow of gases. These...

Pamela L. Nagler, Ibrahima Sall, Armando Barreto-Muñoz, Martha Gómez-Sapiens, Hamideh Nouri, Sattar Chavoshi Borujeni, Kamel Didan
2022, Journal of the American Water Resource Association (JAWRA) (58) 746-784
Revitalization of the Colorado River delta riparian corridor and increasing riparian plant greenness and water use may be accomplished by added water and restoration efforts to offset declines measured since 2000 by Landsat. We use the two-band Enhanced Vegetation Index (EVI2; a proxy for greenness) and evapotranspiration (ET, mm/day) using...
Depositional controls on detrital zircon provenance: An example from upper Cretaceous strata, southern Patagonia

Claudia Ines Galli, editor(s)
2022, Frontiers in Earth Science (10)
Understanding how depositional environments within a sedimentary system redistribute and sequester sediment is critical for interpreting basin-scale provenance trends. However, sedimentary source-to-sink models commonly examine temporal changes and do not consider how variation in sedimentation processes across a dispersal pathway may result in contrasting provenance signatures. In this paper, we...
Using mollusks as indicators of restoration in nearshore zones of south Florida's estuaries
G. Lynn Wingard, Bethany Stackhouse, Andre Daniels
2022, Bulletin of Marine Science (98) 351-380
Current south Florida ecosystem restoration efforts are focused on restoring more natural freshwater flow through the wetlands and into the estuaries to reestablish natural salinity gradients, particularly in the nearshore zones. Indicator taxa are used to monitor and assess restoration progress and the current...
