Forest Stand Structure and Primary Production in relation to Ecosystem Development, Disturbance, and Canopy Composition [PDF]

, 2016
Temperate forests are complex ecosystems that sequester carbon (C) in biomass. C storage is related to ecosystem-scale forest structure, changing over succession, disturbance, and with community composition.

Elevated carbon dioxide and ozone alter productivity and ecosystem carbon content in northern temperate forests [PDF]

, 2014
Three young northern temperate forest communities in the north‐central United States were exposed to factorial combinations of elevated carbon dioxide ( CO 2 ) and tropospheric ozone (O 3 ) for 11 years.

Multidimensional Diversity Identifies Mountains as Key Refugia for Caudata in China

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We identified 14 critical refugia as conservation gaps, emphasizing mountain ecosystems' buffering capacity for Caudate species. Our findings highlight the urgency of adaptive conservation strategies targeting climate refugia and expanding PA networks. ABSTRACT Climate change is reshaping biodiversity patterns, yet conservation planning for amphibians,

Distinct environmental controls on above- and below-ground net primary productivity in Northern China’s grasslands

Ecological Indicators
Grasslands, which cover approximately 40 % of the global land surface, are crucial to the global carbon cycle due to their substantial carbon storage capacity and sensitivity to environmental changes.

Dependence of Biological Activity on the Surface Water Fraction of Planets

, 2019
One of the unique features associated with the Earth is that the fraction of its surface covered by land is comparable to that spanned by its oceans and other water bodies.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Trends in North American net primary productivity derived from satellite observations, 1982-1998 [PDF]

, 2002
Net primary productivity (NPP) in North America was computed for the years 1982–1998 using the Carnegie‐Ames‐Stanford approach (CASA) carbon cycle model.

Global patterns of woody residence time and its influence on model simulation of aboveground biomass [PDF]

, 2017
Woody residence time (τw) is an important parameter that expresses the balance between mature forest recruitment/growth and mortality. Using field data collected from the literature, this study explored the global forest τw and investigated its influence

Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the tropical and the subtropical Atlantic representative of different water bodies (NE Brazil shelf,
