Serological and molecular evaluation of Senecavirus A (SVA) in pigs from farrow-to-finish farms in Minas Gerais, BrazilNARA Subscribed
The emergence of Senecavirus A (SVA) as a causative agent of vesicular diseases in pigs is noteworthy, since it was identified in 2014 through outbreaks in Brazil. The SVA belongs to the Picornaviridae family and is a non-enveloped virus with the ability to adapt to the environment. As the virus’s stability allows it to persist on farms post-outbreak, maintaining stringent biosecurity measures is crucial for effective control....
Functional diversity of Brazilian bees: revealing the unique patterns of the NeotropicsNARA Subscribed
Bees are essential for ecosystem functioning, pollinating many wild and crop plant species. Predicting which species are most vulnerable to global changes, and how their loss may impact ecosystems and human well-being, is critical. Comprehensive information on bee response and effect traits is fundamental to these assessments. However, the Raunkiærian shortfall—insufficient trait data—remains significant for bees, particularly...
Influence of refuge availability on the oviposition strategy of anachoretic and non-anachoretic aphidophagous ladybirdsNARA Subscribed
Scymnus nubilus Mulsant and Coccinella undecimpunctata L. (Coleoptera: Coccinellidae) are two generalist aphidophagous predators abundant in herbaceous habitats. C. undecimpuctata , a larger species, lays its eggs in uncovered clusters, whereas S. nubilus , a tiny species , lays its eggs singly and, possibly, in concealed sites. Reproductive strategies in ladybirds seem to be adaptive, allowing the co-occurrence of both predat...
The COVID-19 pandemic triggered unparalleled political, economic, and social ramifications, exacerbating global food insecurity (FI). To understand the overall impact of the pandemic and how different socio-economic groups were affected, we assessed prevalence and severity of FI in a sample of 18,997 households across seven countries in South America. We employed the Food Insecurity Experience Scale developed by the FAO. Our r...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
Macrolophus pygmaeus (Rambur, 1839) (Hemiptera: Miridae) is a polyphagous predator used in programs of biological control and integrated pest management as a natural enemy against small arthropod pests including whiteflies, thrips, spider mites and aphid. This mirid is also successfully mass reared under factitious prey for commercial purposes. In the present study we assessed and compared the prey consumption, weight gain and...
Atlantic flower–invertebrate interactions: A data set of occurrence and frequency of floral visitsNARA Subscribed
Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time‐consuming, especially in the highly diverse tropics. We aimed to prov...
A roadmap for ladybird conservation and recoveryNARA Subscribed
Ladybirds (Coleoptera: Coccinellidae) provide services that are critical to food production, and they fulfill an ecological role as a food source for predators. The richness, abundance, and distribution of ladybirds, however, are compromised by many anthropogenic threats. Meanwhile, a lack of knowledge of the conservation status of most species and the factors driving their population dynamics hinders the development and imple...
