The climate change projections for the Caatinga biome this century are for an increase in temperature and reduction in rainfall, leading to aridization and plant cover dominated by Cactaceae. The objective of this study was to model the potential distribution of Epiphyllum phyllanthus (L.) Haw., a cactus that is native to the Caatinga biome, considering two possible future climate scenarios, to assess this species' spatio-temporal response to these climate change, and thus to evaluate the need or not for conservation measures. For this purpose, we obtained biogeographic information on the target species from biodiversity databases, choosing nine environmental variables and applying the MaxEnt algorithm. We considered the time intervals 2041-2060 and 2061-2080, centered on 2050 and 2070, respectively, and the greenhouse gas scenarios RCP4.5 and 8.5. For all the scenarios considered, the models generated for 2050 and 2070 projected drastic contraction (greater than 80%) for the areas of potential occurrence of the species in relation to the present potential. The remaining areas were found to be concentrated in the northern portion of the biome, specifically in the northern part of the state of Ceará, which has particular characteristics.

Chemical Characterization and Antimicrobial Activity of Green Propolis from the Brazilian Caatinga Biome.

Green propolis, particularly from the unique flora of the Brazilian Caatinga biome, has gained significant interest due to its diverse chemical composition and biological activities. This study focuses on the chemical characterization and antimicrobial evaluation of Caatinga green propolis. Twelve compounds were isolated through different chromatographic techniques, including flavanones (naringenin, 7--methyleriodictyol, sakuranetin), flavones (hispidulin, cirsimaritin), flavonols (quercetin, quercetin-3-methyl ether, kaempferol, 6-methoxykaempferol, viscosine, penduletin), and one chalcone (kukulkanin B).

The blonde capuchin monkey (Sapajus flavius) was, until a few years ago, an endemic primate of the Atlantic Forest. Today, populations inhabit the Caatinga dry forest and these have been documented using stone tools to access encased foods. It is important to know the distribution of these sites and the characteristics of the stone tools to inform conservation actions for this primate in the Caatinga.

Article Synopsis
- Greenhouse gas emissions are primarily responsible for rising global temperatures, with Brazil's major contributions coming from forestry, land use, and agriculture sectors.
- The study analyzed two GHG inventories (Climate TRACE and SEEG) to assess carbon removal's impact on Brazil's national emissions and investigated how seasonal factors like precipitation and photosynthesis affect these estimates.
- Results showed significant differences in GHG inventory estimates, especially in the forestry sector, with the Caatinga biome contributing nearly 50% to Brazil's carbon removals in 2022, emphasizing the importance of halting deforestation for achieving net-zero emissions.
Akamboja Roza et al., 2017 (Phengodidae: Mastinocerinae) was described to include five species, all from Atlantic Forest, which are characterized by having ten segmented antennae, biflabellate from antennomeres IV-VIII, and with fused flabellae on antennomere IX. The genus comprises six species today, including one from Ilha Grande (Angra dos Reis, Rio de Janeiro State, Brazil) with the IX antennomere flabellae not fused.
