Função discriminatória de lógica Fuzzy para avaliação de cabras expostas a ocorrência de verminose quanto à resistência, resiliência ou sensibilidade ao parasitismo

open access: yesCiência Animal Brasileira, 2023
A incidência de verminose é um dos principais obstáculos para a caprinocultura nos trópicos. A variação individual da resposta do animal à enfermidade existe, mas precisa ser determinado o seu componente genético e estabelecer o manejo zootécnico dos ...

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1263-1287, July 2026.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1399-1416, July 2026.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Morphological and Multilocus Phylogenetic Characterisation of Fusarium Species Causing Fruit Rot in Pumpkins

open access: yesPlant Pathology, Volume 75, Issue 4, July‐August 2026.
Eight Fusarium species are associated with the pumpkin rot in north‐east Brazil. ABSTRACT Pumpkin (Cucurbita) is a cucurbit of great economic and social importance in Brazil. However, fruit rot caused by Fusarium species represents a significant limitation to crop production, compromising quality and hindering commercialisation.

Machine Learning and Geospatial Modelling of Soil Zinc: Implications for Crop Nutrition in the Brazilian Cerrado

open access: yesSoil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT Ensuring sustainable crop nutrition requires improving Zn phytoavailability in weathered and leached tropical soils, which depends not only on available Zn but also on soil pH, texture and P levels. This study developed a digital soil mapping framework for the 200‐million‐hectare Cerrado using 32,272 topsoil (0–20 cm) samples of available Zn ...

Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.
