Testing the Limits of Morphology: A Comprehensive Morphometric Study of the Sister Lineages Lasiocyano Galleti‐Lima, Hamilton, Borges and Guadanucci, 2023 and Lasiodora C. L. Koch, 1850 (Theraphosidae, Mygalomorphae)

Journal of Morphology, Volume 287, Issue 4, April 2026.
An extensive morphometric framework combining linear and geometric morphometry was applied to evaluate interspecific differentiation within the Lasiocyano sazimai and Lasiodora lineage (Theraphosidae). Despite statistically significant differences in some analyses, extensive morphological overlap and high intraspecific variation consistently reduced ...

Butterflies (Lepidoptera: Papilionoidea) and their conservation implications in Pico do Jabre, a montane forest enclave in PARNA Serra do Teixeira, Maturéia, Paraíba, Brazil

EntomoBrasilis
The Caatinga comprises the largest Seasonally Dry Tropical Forest in South America, with humid enclaves known as ‘Brejos de Altitude’, characterized by distinct climate and flora. Pico do Jabre is one such ‘Brejo de Altitude’ and is part of the recently

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, Volume 2026, Issue 4, April 2026.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Florística de uma floresta estacional no Planalto da Borborema, nordeste do Brasil

Rodriguésia
O conhecimento disponível sobre a flora das florestas montanas (Brejo de Altitude) do semiárido de Pernambuco aponta duas situações: uma com maior semelhança à das florestas mais próximas à costa atlântica; e outra mais similar às florestas mais secas do

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

State of knowledge and conservation of the snake fauna of the “Brejos de Altitude” in the Pernambuco Endemism Center, Northeastern Brazil

Ethnobiology and Conservation, 2020
The Atlantic Forest is originally distributed along the Brazilian coast from the states of Rio Grande do Norte to Rio Grande do Sul, and it presents many different vegetal physiognomies. Brejos de Altitude is a set of relict altitudinal forests in northeastern Brazil with a distinct and poorly studied biota representing special areas within the ...

Amid the fallen leaves: Intense collecting in the Northern Atlantic Forest reveals new minute harvestmen species (Opiliones: Stygnidae) within the Area of Endemism of Pernambuco

Austral Entomology, Volume 64, Issue 4, November 2025.
Abstract Stygnids represent one of the most diverse harvestman families, with many endemic species in the Area of Endemism of Pernambuco, a pattern increasingly evident by intensified sampling in the region over the years. The area is also recognised for hosting a group of understudied minute leaf‐litter dwellers stygnids, represented by the following ...
