Exploring portable NIR spectroscopy in transmittance and reflectance modes for the authentication of Brazilian coffees with geographical indications. [PDF]

J Sci Food Agric
Abstract BACKGROUND Geographical indications (GIs) certify the link between coffee origin and quality, enabling premium pricing and protecting producers. However, the high market value of GI coffees increases their vulnerability to fraud, underscoring the need for reliable and practical authentication methods.

Montane diversification as a mechanism of speciation in neotropical butterflies [PDF]

Ecology and Evolution
The mountains in the Atlantic Forest domain are environments that harbor a high biodiversity, including species adapted to colder climates that were probably influenced by the climatic variations of the Pleistocene.

Forest Cover and Altitude Are Key to the Occurrence of Black-Fronted Titi Monkeys (Callicebus nigrifrons) in the Brazilian Atlantic Forest. [PDF]

Am J Primatol
Conceptual diagram illustrating how altitude and forest cover jointly influence the probability of primate occurrence. Higher altitudes and greater forest cover are associated with increased occurrence probability. Icons on the axes represent gradients of altitude (left) and forest cover (bottom), while primate silhouettes depict different ...

Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii - enemy release and plant-soil feedbacks. [PDF]

New Phytol
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Dispersal Ability Reduces Thermal Specialization and Prevents Climate-Driven Extinctions in a Neotropical Rainforest. [PDF]

Glob Chang Biol
We found that species with higher dispersal ability are less specialized in their temperature tolerances and more likely to persist under climate change. By analyzing more than 6 thousand species of plants, invertebrates, and vertebrates distributed in the Atlantic Rainforest, we show that more mobile species can avoid extinction by shifting locations,

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda). [PDF]

Cladistics
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Lithobiomes Heterogeneity and Geographic Distance Shape the Landscape Genomics Within Brazilian Mountain Systems. [PDF]

Ecol Evol
Genomic analyses of Paepalanthus calvus across Brazilian montane ecosystems reveal strong population structure shaped by geographic distance and lithological heterogeneity. Fine‐scale edaphoclimatic factors are the main predictors of genetic divergence among distinct lithobiomes, underscoring the role of substrate‐driven ecological isolation and local ...

Ecological and Historical Correlates of Taxonomic, Phylogenetic, and Functional Diversity of Amphibians in South American Rainforests and Savannas. [PDF]

Ecol Evol
This study identifies the key drivers of anuran amphibian diversity (taxonomic, functional, and phylogenetic) across South America's Cerrado, Amazonia, and Atlantic Rainforest. Although taxonomic and phylogenetic diversity consistently increased with long‐term climatic stability in all regions, functional diversity was primarily influenced by current ...

Composition and natural history of the snakes from the Parque Estadual da Serra do Papagaio, southern Minas Gerais, Serra da Mantiqueira, Brazil [PDF]

ZooKeys, 2018
The Serra da Mantiqueira is one of the least inventoried physiographic areas of southeastern Brazil. There is great potential for detection of endemic species for which little or nothing is known about basic aspects of natural history.
