From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti

open access: yesPest Management Science, Volume 82, Issue 4, Page 3395-3407, April 2026.
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...

Spatial patterns and estimates of global forest litterfall [PDF]

open access: yesEcosphere, 2019
AbstractThe quantitative knowledge of global forest litterfall is very important for understanding the global biogeochemical cycle and evaluating of forest ecosystem services. Our aims are to show the spatio‐temporal patterns of forest litterfall and the variation in different forest types and climate zones in the world.

Litterfall Production and Nutrient Deposition Through Leaf Fallen in three Tamaulipan Thornscrub Communities, North-eastern Mexico

open access: yesInternational Journal of Bio-Resource and Stress Management, 2023
Litterfall and the contents of macro- and micro-nutrients derived from its decomposition contribute greatly to the growth and productivity of forest ecosystem.

Forest health, heart rot disease, and their impact on the source of carbon‐based greenhouse gas fluxes

open access: yesNew Phytologist, Volume 250, Issue 2, Page 921-933, April 2026.
Summary Forest health is critical for sustaining ecosystem services like carbon sequestration. Heart rot, a widespread disease in upland northern hardwood forests, may affect greenhouse gas (CO2 and CH4) fluxes, but its impacts remain poorly measured. Using non‐destructive tomography and direct gas flux measurements, we quantified the effects of heart ...

CARBON BALANCE AND VEGETATION DYNAMICS IN AN OLD‐GROWTH AMAZONIAN FOREST [PDF]

open access: yes, 2004
Amazon forests could be globally significant sinks or sources for atmospheric carbon dioxide, but carbon balance of these forests remains poorly quantified.

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

open access: yesEcography, Volume 2026, Issue 3, March 2026.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Temperature controls bryophyte‐associated nitrogen fixation in super‐humid temperate forests in New Zealand

open access: yesEcology, Volume 107, Issue 3, March 2026.
Abstract Nitrogen (N) fixation performed by certain prokaryotes (diazotrophs) is a key source of new N in pristine ecosystems. Diazotrophs associate with various plants, including bryophytes—the dominant plant group in northern ecosystems such as boreal forests. There, bryophyte‐associated N2 fixation contribute half of total ecosystem N input. However,

RELAÇÃO ENTRE SUCESSÃO SECUNDÁRIA, SOLO E SERAPILHEIRA EM UMA RESERVA BIOLÓGICA NO ESTADO DO RIO DE JANEIRO, BRASIL

open access: yesCiência Florestal, 2018
The nutrient cycling is influenced by the successional stage. However, there is disagreement in relation to the pattern of this dynamic. The present study aimed to evaluate the chemical attributes of the topsoil and litterfall in two abandoned ...

Evaluation of Top‐Down and Bottom‐Up Global Terrestrial Respiration Estimates and Their Mismatch With Model Simulations

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Terrestrial respiration is one of the poorly understood processes in the global carbon cycle. However, expanding observations and machine learning approaches have led to a proliferation of estimates. We compiled total ecosystem and heterotrophic respiration estimates derived from top‐down atmospheric inversions and bottom‐up upscaling of ...

Integrating remote sensing datasets into ecological modelling: a Bayesian approach [PDF]

open access: yes, 2008
Process-based models have been used to simulate 3-dimensional complexities of forest ecosystems and their temporal changes, but their extensive data requirement and complex parameterisation have often limited their use for practical management ...
