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

open access: yesEntomoBrasilis
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

Climatic Stress Versus Anthropogenic Degradation: An Ecohydrological Perspective on the Drivers of Net Primary Productivity in a Seasonally Dry Tropical Forest

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Water‐limited ecosystems play a fundamental role in the global carbon cycle, yet they have been increasingly affected by pressures from aridification and land‐use and land‐cover change. The Caatinga, the largest seasonally dry tropical forest in South America, exhibits strong ecohydrological coupling resulting from centuries of adaptation, in ...

Sensibilidade do modelo SiSPAT em área de brejo de altitude no Nordeste do Brasil

open access: yesJournal of Environmental Analysis and Progress, 2016
A compreensão e a quantificação das trocas de água e de energia são importantes para propósitos meteorológicos, agronômicos e hidrológicos. Os processos biofísicos envolvidos nessas trocas são numerosos e complexos, dificultando sua medição direta em grandes áreas, de forma contínua e num grande intervalo de tempo, devido ao grande número de ...

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

open access: yesRodriguésia
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

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)

open access: yesJournal 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 ...

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

open access: yesNordic 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 ...

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

open access: yesEthnobiology 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 ...

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

open access: yesInternational 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 ...

Edge effect on vascular epiphytic composition in a fragment of Atlantic Forest in northeastern Brazil

open access: yesActa Botânica Brasílica, 2015
Epiphytes are common in the canopy of temperate and tropical forests, where they substantially contribute to species diversity and to key ecosystem processes.
