A large, infrequent ecosystem subsidy (cicada carcasses) and warming additively accelerate development and increase growth of larval amphibians

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S332-S351, December 2025.
Abstract Many ecosystems receive resource subsidies that affect productivity and food webs. Ecosystem subsidies vary in quantity, quality, and timing, and effects are often mediated by environmental factors, including temperature. Deposition of periodical cicada carcasses into ponds represents a large, high‐quality, infrequent subsidy.

Comparison of ecosystem processes in a woodland and prairie pond with different hydroperiods [PDF]

open access: yes, 2017
Shallow lakes and ponds constitute a significant number of water bodies worldwide. Many are heterotrophic, indicating that they are likely net contributors to global carbon cycling. Climate change is likely to have important impacts on these waterbodies.

Aquatic Productivity Signals in the Kolyma River (Northeastern Siberia) From O2/Ar Ratios and O2 Triple Isotopologues

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Arctic rivers are intricate water networks that chemically and biologically process carbon before releasing it as carbon dioxide (CO2) into the atmosphere or carrying it to the ocean. Primary producers use inorganic carbon to build biomass at the base of the trophic chain.

The interannual variability of Africa's ecosystem productivity: a multi-model analysis [PDF]

open access: yes, 2008
We are comparing spatially explicit process-model based estimates of the terrestrial carbon balance and its components over Africa and confront them with remote sensing based proxies of vegetation productivity and atmospheric inversions of land ...

Predicting Ecosystem Respiration Under Climate Extremes Requires Varying Parameters

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract Ecosystem respiration (ER) is the second‐largest terrestrial carbon flux, yet ecosystem models often fail to capture its variability under climatic extremes. The increasing frequency and severity of precipitation and drought extremes pose substantial challenges to accurately predicting ER. It remains unclear whether parameters calibrated under

Carbon Consequences of Forest Disturbance and Recovery Across the Conterminous United States [PDF]

open access: yes, 2012
Forests of North America are thought to constitute a significant long term sink for atmospheric carbon. The United States Forest Service Forest Inventory and Analysis (FIA) program has developed a large data base of stock changes derived from consecutive

Shadow Education in the Soviet and Post‐Soviet Eras: A Political‐Economic Analysis of Changing Tides

open access: yesEuropean Journal of Education, Volume 60, Issue 4, December 2025.
ABSTRACT Focusing on the shadow education system of private supplementary tutoring, this paper contains comparisons over time and place in the distinctive circumstances of the Soviet Union and the 15 independent countries that emerged following its collapse in 1991. The paper uses the lenses of politics and economics to understand changing tides in the
