Historical anthropogenic stressors affect bird ecology and feather development in neotropical forests

open access: yesOikos, EarlyView.
Fragmentation and habitat loss driven by agricultural expansion have significantly affected bird ecology. Additionally, the growing use of agrochemicals impacts ecosystems and avian communities. Tools such as isotopic analysis provide reliable proxies for assessing organisms' habitat use and diet, and can also reflect environmental alterations, such as

Exploring a Water–Ethyl Acetate System for the Efficient Synthesis of 4‐Aryl Quinolines

open access: yesChemistryOpen, EarlyView.
A sustainable and catalyst‐free method for synthesizing 4‐aryl quinolines is developed using a water–ethyl acetate solvent system under reflux conditions. This approach eliminates hazardous reagents while achieving high yields and purity. The protocol aligns with green chemistry principles, offering an efficient and environmentally friendly alternative

SiO2@Benzothiazole‐Cl@Fc as an Efficient Heterogeneous Catalyst for the Synthesis of 1,3,5‐Trisubstituted Pyrazoles by A3 Coupling

open access: yesChemistryOpen, EarlyView.
This research introduces the preparation and analysis of a newly heterogeneous catalyst developed silica nanospheres supporting a ferrocene‐containing ionic liquid (SiO2@Benzothiazole‐Cl@Fc) for the A3 coupling reaction. The catalyst facilitates the efficient synthesis of 1,3,5‐trisubstituted pyrazoles from aromatic hydrazides, aldehydes, and aromatic ...
