Long‐term fallows rate best among agri‐environment scheme effects on farmland birds—A meta‐analysis

open access: yesConservation Letters, 2022
Agri‐environment schemes (AES) serve to counteract the ongoing decline of farmland bird populations, but their success remains controversial. We conducted a meta‐analysis to compare standardized effect size estimates among European AES options—classified

Temporal and Spatial Data Mining with Second-Order Hidden Models [PDF]

open access: yes, 2005
In the frame of designing a knowledge discovery system, we have developed stochastic models based on high-order hidden Markov models. These models are capable to map sequences of data into a Markov chain in which the transitions between the states depend

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Influence de la rotation culturale, de la fertilisation et du labour sur les populations de nématodes phytoparasites du sorgho (Sorghum bicolor (L.) Moench) [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2012
Influence of crop rotation, fertilization and tillage on populations of plant parasitic nematodes of sorghum (Sorghum bicolor (L.) Moench). The soil nematodes of three long-term trials (1960, 1980 and 1990) representing the production of sorghum (Sorghum

Implementing potential climate‐smart practices through diverse partnerships

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Solar farms can mitigate negative impacts of whiplash weather on plant communities in a dryland ecosystem

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Utility‐scale solar energy (USSE) development generates novel questions regarding coupling clean energy production with terrestrial ecosystem services (e.g., forage production, pollinator support). We found that a USSE array sited in a fallowed cropland maintained a reseeded native plant community even a decade post‐restoration and that the array ...

Weeds in a changing climate: Competitors or service plants?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

Carbon and Water Budgets in Multiple Wheat-Based Cropping Systems in the Inland Pacific Northwest US: Comparison of CropSyst Simulations with Eddy Covariance Measurements

open access: yesFrontiers in Ecology and Evolution, 2017
Accurate carbon and water flux simulations for croplands are greatly dependent on high quality representation of management practices and meteorological conditions, which are key drivers of the surface-atmosphere exchange processes.

Field margins as rapidly evolving local diversity hotspots for ground beetles (Coleoptera : Carabidae) in northern China [PDF]

open access: yes, 2006
The diversity of carabid assemblages at newly established field margins was compared to the diversity in surrounding fields and woodland habitats at Dongbeiwang village, Beijing.

Targeted herbicide spraying systems: role of nozzle type, number of nozzle activation, nozzle orientation, and boom height on spray coverage and weed control

open access: yesPest Management Science, EarlyView.
Targeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.
