Origins and Diversification of the Caatinga Dry Forest Endemic Avifauna

open access: yesJournal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim Understanding the geographic origin of lineages is critical to comprehending their biogeographical and evolutionary histories and the historical connections among biomes. In northeastern Brazil, the Caatinga dry forest represents the largest and most biologically diverse patch of Seasonally Dry Tropical Forest in the Neotropics.

On Northeast Brazil Orographic Enhanced Rainfall and Monsoon Dynamics

open access: yesInternational Journal of Climatology, Volume 45, Issue 10, August 2025.
We provide an updated rainfall climatology (1990–2020) for Northeast Brazil which discusses the role of orographically enhanced rainfall and monsoon dynamics on this climate system. Our work presents strong evidence that this continental‐scale region is under a more extensive influence of the South American Monsoon System than previously described ...

Alterações microclimáticas em área de Brejo de Altitude associadas a influência do desmatamento

open access: yesCONTRIBUCIONES A LAS CIENCIAS SOCIALES
As atividades humanas têm resultado em desmatamento e consequências ambientais, tais como: alterações na qualidade da água, diminuição da biodiversidade e aumento da poluição. A restauração dessas áreas degradadas é crucial para recuperar a integridade do ecossistema.

Ação antrópica na produção de alimentos em áreas de Brejos de Altitude no semiárido do Nordeste, Brasil

open access: yesRevista Ibero-Americana de Ciências Ambientais, 2020
Os brejos de altitude são unidades biogeográficas peculiares pois são um conjunto de áreas de florestas úmidas rodeadas por vegetação xerófila típica de Caatinga. O objetivo deste trabalho foi observar a influência das alterações ambientais na produção das culturas tradicionais no município de Garanhuns, utilizando para isso  dados pluviométricos ...

Assessing the current distribution and potential habitat availability for Kaempfer's tody‐tyrant: a restricted‐range and threatened species from the Atlantic Rainforest

open access: yesWildlife Biology, Volume 2025, Issue 4, July 2025.
Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes are more likely to become extinct. The prevention of extinctions is an urgent matter and knowledge on the ecology and distribution of threatened species is required to outline conservation strategies.

From Hot to Cold Spots: Climate Change is Projected to Modify Diversity Patterns of Small Mammals in a Biodiversity Hotspot

open access: yesDiversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Climate change represents one of the main threats to global biodiversity, and such alterations are expected to induce shifts in distribution ranges and diversity patterns. We evaluate if protected areas and forest remnants in the Atlantic Forest in South America (AF) are projected to ensure the taxonomic diversity (TD) and phylogenetic ...

Paisagem urbana, vulnerabilidade e risco em brejos de altitude: o sítio urbano de Areia/PB

open access: yesNature and Conservation, 2018
A expansão urbana nos países subdesenvolvidos pode se tornar um problema catastrófico quando acontece em terrenos ambientalmente instáveis. A geomorfologia urbana é a ciência que estuda os sítios urbanos pelo viés das características do relevo e suas interrelações com outros componentes da paisagem, como o clima, meteorologia, geologia, vegetação e uso

Vertebrate taxonomic and functional hotspots in the Brazilian Atlantic Forest

open access: yesDiversity and Distributions, Volume 30, Issue 9, September 2024.
Abstract Aim We aim to find the main drivers of the taxonomic and functional richness and functional dispersion of vertebrates (amphibians, birds, primates, marsupials, rodents, bats and medium‐ and large‐sized mammals) across the Brazilian Atlantic Forest.
