An experimental test on the effects of dispersal from different habitat sources on community structure. [PDF]

Ecology
Abstract Biological interactions, disturbances, and demographic stochasticity often drive population declines and local extinctions. Dispersal can counterbalance these drivers by rescuing small populations or facilitating recolonization. Using freshwater zooplankton in experimental mesocosms, we tested three hypotheses: (1) isolated sites would ...

Synthesis and In Vitro Activity of Hypofuran B and Analogs Against Plasmodium Falciparum and Trypanosoma Cruzi. [PDF]

ChemMedChem
Hypofuran B, drynaran, and a series of analogs are obtined by crossed aldol condensation from furfural dereivatives. Compunds are tested for in vitro activity agaisnt Trypanosoma cruzi and Plasmodium falciparum. Best results are obtained Against P. falciparum, with IC50 values ranging from 5,35 to 10,35 µg mL−1.

Designing Atomically Precise and Robust COF Hybrids for Efficient Photocatalytic CO₂ Reduction. [PDF]

Small
The rational design of a novel covalent organic framework (COF)‐based hybrid CO2 photocatalyst allows for the atomistic level‐resolution of immobilized Rhenium(I) centers in the porous structure. The ReI‐decorated dibenzochrysene COF shows outstanding photocatalytic performance with a CO production rate of 1.16 mmol g−1 h−1 and long‐term photostability

Surface Charge Modulation in Covalent Organic Frameworks for Controlled Pt-Photodeposition and Enhanced Photocatalytic Hydrogen Evolution. [PDF]

Small
This study demonstrates that the photocatalytic hydrogen evolution efficiency of COFs can be effectively controlled by modulating surface charge via post‐synthetic linkage conversion from imine to amide. This unique interfacial modification approach switches the surface charge of COFs and introduces a shift in the reaction mechanism of the in situ Pt ...

The Weight of Genetic Drift: A Pedigree-Based Evaluation of the Breton Horse Population in Brazil. [PDF]

Vet Med Int
The genetic diversity of Breton horses in Brazil is a critical concern, mainly due to the small population size and low number of births per year. Given that the inbreeding was overlooked by breeders for multiple generations, we estimated the genetic diversity of this population utilizing pedigree‐based measures of population diversity. A total of 1394

Ultrasound of the Lacrimal Gland in Healthy Shih Tzu Dogs and with Dry Eye Disease. [PDF]

Vet Med Int
Dry eye disease (DED) is a very common disease in dogs, especially that of immune‐mediated origin, with Shih Tzu dogs being some of the most affected. In this study, ultrasound changes of the orbital lacrimal gland (LG) were described in healthy Shih Tzu dogs and those diagnosed with different intensities of DED.

GIS-based G × E modeling of maize hybrids through enviromic markers engineering. [PDF]

New Phytol
Summary Through enviromics, precision breeding leverages innovative geotechnologies to customize crop varieties to specific environments, potentially improving both crop yield and genetic selection gains. In Brazil's four southernmost states, data from 183 distinct geographic field trials (also accounting for 2017–2021) covered information on 164 ...

Physiology and production of cherry tomato cultivars in a hydroponic system using brackish water [PDF]

Revista Brasileira de Engenharia Agrícola e Ambiental, 2021
Agricultural production has become a challenge in arid and semi-arid regions due to the scarcity of water for irrigation, so brackish water is commonly used.

COMBINATION OF Azospirillum brasilense AND Bradyrhizobium japonicum IN THE PROMOTION OF INITIAL CORN GROWTH

Revista de Agricultura Neotropical, 2021
Biological formulations used as inoculants are increasingly present in grasses, especially in corn. Positive results in promoting plant growth, with different associations with diazotrophic bacteria, show these capacities of interaction to act as plant ...
