Passion fruit, a tropical species cultivated across various nations, faces challenges in expanding its cultivation areas due to several constraints, including total crop losses, caused by the fruit woodiness virus. In Brazil, this condition is attributed to the cowpea aphid-borne mosaic virus (CABMV), and currently, no passion fruit cultivars are resistant to this virus. This study integrates classical breeding and molecular a...

Aspergillosis is a disease caused by species of fungi of the genus Aspergillus sp. and is important for wild birds. A female budgerigar ( Melopsittacus undulatus ) presenting with dyspnea, apathy, anorexia, ruffled feathers, and drowsiness with abnormal tail movements, suggesting respiratory distress, was treated in the emergency room at the Center for Wildlife Medicine and Research. The animal died and the body was sent to th...

The seasonality of forage production is one of the main challenges in semi-arid regions, where environmental conditions limit agricultural productivity. One promising option is the use of elephant grass ‘BRS Capiaçu’, together with deficit irrigation. This study evaluated the impact of different irrigation depths with brackish water (50%, 75%, 100% and 125% of the reference evapotranspiration – ET 0 ) on the productive, physio...

Process-based agro-hydrological models are essential tools for assessing crop growth and yield under contrasting management and environmental conditions. This study assessed the performance of the coupled Soil-Water-Atmosphere-Plant and World Food Studies Simulation Model (SWAP–WOFOST) to simulate cotton ( Gossypium hirsutum L., cv. FiberMax 975 Wild Strike ® ) growth and yield under tropical Cerrado conditions in western Bahi...

Adopting resilient practices is crucial to balancing food production and crop sustainability in semiarid regions. Therefore, adopting systems that provide greater stocks of water, carbon, and nutrients at the soil-plant interface is crucial. The objective of this study was to assess water, carbon, and nutrient stocks in the soil-plant systems of irrigated forage crops in the semiarid region of Brazil. The study was conducted i...

In the face of climate change, agricultural modelling combined with experimental research is essential for predicting yields in diverse climatic scenarios. This study calibrated, validated and applied the AquaCrop model for forage sorghum under future climate scenarios in a semi‐arid region between 2020 and 2022. Meteorological data, soil moisture, canopy cover and crop productivity were collected. Model performance was evalua...

Background: The stink bug complex is one of the most damaging pests of soybean, reducing yield and seed quality. Genetic resistance remains the most sustainable and effective management strategy, but its quantitative inheritance and labor-intensive field phenotyping make its implementation in breeding programs challenging. Objective: This study explored high-throughput phenotyping (HTP) using unmanned aerial vehicles (UAVs) eq...

Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles, water replenishment, use of soil cover and production arrangements based on the main cr...

This study aimed to evaluate the agronomic performance, crop evapotranspiration (ET c ), crop coefficients (K c , K cb and K e ) and yield response factor (K y ) of three forage cactus clones—Orelha de Elefante Mexicana (OEM), Miúda (MIU) and IPA Sertânia (IPA)—grown in a semiarid environment. Four experiments involving different irrigation strategies and the use of mulch were conducted between 2012 and 2020. The OEM clone pre...

Salmonid species have increasingly been established in South America for aquaculture and recreational fishing purposes. This study provides the first scientific record of the Chinook salmon ( Oncorhynchus tshawytscha ) in the Patos Lagoon (32°S), the world's largest choked coastal lagoon. The specimen was a female with 770 mm (total length), 3992.1 g, estimated age of 6 years and an advanced sexual maturation stage. Based on m...
