Assessment of farmer’s knowledge and attitudes toward fungi and mycotoxin conta...
Bila, João; Macuamule, Custódia; Bombe, Amina; Ribeiro, Maria Isabel; Venâncio, Armando; Afonso, Sandra; Rodrigues, PaulaIn Mozambique, 80% of the population directly depends on agriculture as a source of food and income. However, some of the most produced food crops, such as maize, rice and peanuts, are easily contaminated by fungi and mycotoxins. The naturally high prevalence of mycotoxins can be aggravated by the high vulnerability and lack of knowledge of the farmers. The aims of this study were to assess the knowledge and pe...

Evolution and genetic architecture of sex-limited polymorphism in cuckoos
Merondun, Justin; Marques, Cristiana I; Andrade, Pedro; Meshcheryagina, Swetlana; Galván, Ismael; Afonso, Sandra; Alves, Joel M; Araújo, Pedro M.Sex-limited polymorphism has evolved in many species including our own. Yet, we lack a detailed understanding of the underlying genetic variation and evolutionary processes at work. The brood parasitic common cuckoo (Cuculus canorus) is a prime example of female-limited color polymorphism, where adult males are monochromatic gray and females exhibit either gray or rufous plumage. This polymorphism has been hypo...
Aflatoxin Contamination of Various Staple Foods from Angola and Mozambique
Matusse, Cláudio; Lucamba, Zelda; Bila, João; Macuamule, Custódia; Sampaio, Ana; Afonso, Sandra; Venâncio, Armando; Rodrigues, PaulaAflatoxins constitute a significant risk in staple foods produced in African countries. This research aimed to analyze the total aflatoxin (AFT) contamination of various staple foods in Angola and Mozambique. A total of 233 samples of corn, peanuts, beans, rice, and cassava flour collected from farmers or local markets from the province of Cuanza Sul, Angola, and the provinces of Gaza and Inhambane, South Mozam...
Comparing the sensitivity of aquatic organisms relative to Daphnia sp. toward e...
Afonso, Sandra; Ferreira, Verónica; Moreira-Santos, MatildeInterest on aromatic and medicinal plants (AMP)-based products, especially crude extracts (CE) and essential oils (EO), has increased over recent years due to their bioactive and biopesticide properties, though a variety of these compounds is environmentally damaging. Aquatic organisms can easily be exposed to the toxicological risks of AMP-based products, but research exploring existing ecotoxicity data to non...

Composts obtained by mixing hop leaves with wheat straw or farmyard manure impr...
Afonso, Sandra; Pereira, Ermelinda; Arrobas, Margarida; Rodrigues, M.A.; Choupina, AltinoHop (Humulus lupulus L.) leaves are rich in nutrients, particularly nitrogen (N). After harvest, they can be recycled through composting for use as a soil amendment. In this study, we report the effect of composts obtained from mixtures of hop leaves with other organic materials (wheat straw, farmyard manure, and ash from hop stems) at different ratios on soil properties and microbial diversity. Data on total N...
Isolation of filamentous fungi from different food matrices from Angola and Moz...
Vale-Dias, Teresa; Matusse, Cláudio; Carvalho, Susana; Silva, Beatriz; Soares, Célia; Lucamba, Zelda; Afonso, Sandra; Venâncio, ArmandoAgriculture remains the main economic activity in most African countries. However, crops are often contaminated with fungi that can cause diseases or produce mycotoxins, which is a major concern to food safety and security. Little is known about the mycotoxigenic fungi contaminating the most relevant staples in Mozambique and Angola. The aim of this work was to isolate and identify fungi from three food commodi...

A Network-DEA model to evaluate the impact of quality and access on hospital pe...
Afonso, Sandra; Ferreira, Diogo; Figueira, J. R.The relationship between efficiency, quality, and access in healthcare is far from being well defined. In particular, there is no consensus on whether there is a trade-off between hospital performance and its social dimensions, such as the care appropriateness, safety, and access to proper health care. This study proposes a new approach based on the Network Data Envelopment Analysis (NDEA) to evaluate the exist...
