A Review of Angular Leaf Spot Resistance in Common Bean

Crop Science, Volume 59, Issue 4, Page 1376-1391, July-August 2019., 2019
ABSTRACT Angular leaf spot (ALS), caused by Pseudocercospora griseola, is one of the most devastating diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical production areas. Breeding for ALS resistance is difficult due to the extensive virulence diversity of P. griseola and the recurrent appearance of new virulent races.

Evaluation of a novel anti‐mycotoxin agent specific for aquatic species in mitigating aflatoxin B1‐induced changes in Nile tilapia: A comprehensive study

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Aflatoxin B1 (AFB1) contamination of aquaculture feed poses serious health risks to fish and consumers. In this study, the efficacy of a novel anti‐mycotoxin agent specific for aquatic species (AM‐AQ) containing bentonite, sepiolite, and orange peel meal (Citrus Sinensis) in alleviating AFB1 toxicity in Nile tilapia (Oreochromis niloticus) was

Morphological and Genetic Structure of Two Equivalent Astyanax Species (Characiformes: Characidae) in the Region of Paranaíba Arc

The Scientific World Journal, Volume 2019, Issue 1, 2019., 2019
The Astyanax scabripinnis complex is composed of a large number of almost morphological indistinguishable species, including Astyanax paranae and Astyanax rivularis, which exist in the Paraná and São Francisco Basins, respectively, and sometimes are considered subspecies of the A. scabripinnis group or even are cited just as A. scabripinnis.

Heterogeneity and scaling of photosynthesis, respiration, and nitrogen uptake in three Atlantic Rainforest streams

Ecosphere, Volume 8, Issue 9, September 2017., 2017
Abstract Leaves, epilithon, macrophytes, and fine benthic organic material are central ecosystem compartments to food webs and mediate nutrient fluxes in streams. Most estimates of gross primary production (GPP) and ecosystem respiration (ER) are made at a reach scale, averaging across compartments.

Insights on factor analysis applied to multi‐trait and multi‐environment selection of common bean lines

Crop Science, Volume 65, Issue 4, July/August 2025.
Abstract One of the objectives of common bean (Phaseolus vulgaris L.) breeding programs is selection of lines with superior agronomic traits that are adapted to different environmental conditions. Thus, the aim of this study was to verify the applicability of factor analysis as a strategy to assist the selection of common bean lines for multi‐traits in

Recent advancements in aquaponics with special emphasis on its sustainability

Journal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract An aquaponic system which is an integration of hydroponics with aquaculture is sustainable, ecologically friendly, and uses non‐renewable resources with very high efficacy. The increasing trend in aquaponics research demonstrates a growing recognition of its potential to address critical global issues such as food security, water conservation,
