Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

Journal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

End‐to‐End Convolutional Neural Networks Training on Stable Diffusion Deepfake Imagery for Precise Early Weed Detection

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT The integration of optical sensor systems with advancements in artificial intelligence for image processing presents a promising avenue for the broader implementation of site‐specific weed management (SSWM). Convolutional neural networks (CNNs) have significantly advanced the field of weed detection.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling

Molecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Vibrational Order, Structural Properties, and Optical Gap of ZnO Nanostructures Sintered through Thermal Decomposition

Journal of Nanomaterials, Volume 2014, Issue 1, 2014., 2014
The sintering of different ZnO nanostructures by the thermal decomposition of zinc acetate is reported. Morphological changes from nanorods to nanoparticles are exhibited with the increase of the decomposition temperature from 300 to 500°C. The material showed a loss in the crystalline order with the increase in the temperature, which is correlated to ...
