Summary: In this study, the label-free mass spectrometry proteome of Erythroxylum pungens (roots, barks, leaves) harvested from its natural habitat was described. It was found that processes related to defense were most important in roots, and there were different main protective proteins among organs, indicating part-specific strategies of environmental adaptation.

Summary: Spatial variability is more evident than temporal variability in the water quality of non-perennial rivers, with interannual variability being more relevant than seasonal variability at the temporal scale. Wastewater discharge appears to attenuate the seasonal hydrological effect on water quality.

Summary: The improper management and exploitation of semiarid Planosols' natural resources have led to irreversible degradation processes, impacting the ability of vegetation to naturally reestablish. Research on preserved and degraded Planosols in Pernambuco State, Brazil revealed that while microbial activity in degraded soils helped maintain soil nitrogen stocks, carbon stocks were significantly reduced. Microbial biomass and activity did not differ significantly between the two types of Planosols, suggesting a lack of metabolic stress from the identified microbiota.

Summary: The main effects of trypanosomosis in Brazil are related to reproductive alterations, with a study in the semiarid region of Northeastern Brazil showing that abortions in goats and sheeps were associated with Trypanosoma vivax infection. PCR analysis identified 100% infection rate of T. vivax in aborted animals, along with the presence of the parasite DNA in the blood of fetuses, confirming congenital transmission. High parasitemia and clinical signs of trypanosomosis were observed in the aborted animals.

Summary: Soil salinization and sodification are major threats to semiarid agroecosystems, and this study aimed to diagnose the salinity status of the soil under different land-use conditions in Northeast Brazil. The results showed that sodium and chloride were the main soluble ions in cultivated and desertified areas, and sulfate was also present in significant levels in desertified areas. Calcium, magnesium, sodium, and chloride ions were positively correlated with variables that degrade soils. These findings are important for maintaining the sustainability of agricultural production.

Summary: Hunting with dogs is an important activity for the survival of the human population in the Brazilian semiarid region. However, it can have implications for game species conservation. This study analyzed the patterns of hunting with dogs activities by characterizing hunters' and hunting dogs' profiles, investigating target and nontarget prey species, hunters' practices, motivations, and perceptions. The findings showed that hunters using dog assistance were mainly men, engaged in agriculture with low income and education. The motivations for hunting with dogs included food, sport, and trade. There were twenty species captured by dogs, but only six were target prey when hunting with dogs. Hunters perceived hunting with dogs to be three times more efficient.

Summary: Erythroxylum macrophyllum is a species complex in Central and South America, with a wide distribution and several sub-specific taxa. A unique savanna variety in the Colombo-Venezuelan region can be distinguished from the rest of the complex by morphological characteristics. Molecular phylogenetic analysis shows that this savanna variety is more closely related to E. acuminatum and E. pauciflorum than to E. macrophyllum, suggesting a polyphyletic taxonomic section. Therefore, the proposal is made to elevate this variety to the status of a separate species, Erythroxylum savannarum.

Summary: In a study on pseudoscorpions in caves in northeastern Brazil, eight species were identified. The distribution of several species including Pseudochthonius biseriatus Mahnert, 2001, Cryptoditha aff. elegans, Parachernes (P.) nitidimanus (Ellingsen, 1905), Petterchernes brasiliensis Heurtault, 1986, Ceriochernes foliaceosetosus Beier, 1974, and Progarypus setifer Mahnert, 2001 has been extended to include the State of Pernambuco. Additionally, two new species, Geogarypus gollumi sp. nov. (Geogarypidae) and Progarypus smaugi sp. nov. (Hesperolpiidae), have been described.

Summary: In this paper, the authors use remote-sensing images to monitor the water quality of reservoirs in semiarid Northeast Brazil. They establish a retrieval model to estimate the concentration of chlorophyll-a and validate its accuracy. The study shows the influence of seasonality and meteorological factors on reservoir water quality, and highlights the usefulness of satellite data for monitoring and assessing changes in water quality.

Summary: This article describes three new pseudoscorpion species, Pseudochthonius pali sp. nov., Pseudochthonius diamachi sp. nov., and Pseudochthonius koinopoliteia sp. nov., found in caves in Bahia state, Brazil. They can be differentiated from other species based on characteristics such as the absence of eyes or eyespots, chelal and cheliceral dentition, coxal chaetotaxy, and body size. The article also provides ecological remarks, discusses potential threats, offers recommendations for future research, and includes a key for identifying Pseudochthonius species from Brazil.

Summary: In this study, a taxonomic treatment of Croton sect. Lasiogyne occurring in Brazil is presented. The research is based on field collections and analyses of more than 1,300 specimens held in 47 herbaria. Eleven species are recorded, with six of them being endemic to Brazil. Morphological characteristics such as the absence of extrafloral nectaries and specific sepal shapes are proposed for species recognition.

Summary: The genus Thyrsacanthus (Acanthaceae) was established again to accommodate South American species of Anisacanthus that are phylogenetically distinct from the main Anisacanthus lineage. This study confirms that A. pohlii is a synonym for Thyrsacanthus ramosus and classifies A. trilobus within Justicia based on macromorphological, palynological, and molecular data. Additionally, lectotypes for Drejera ramosa and Anisacanthus pohlii were selected.

Summary: Understanding the recovery time of vegetation structure and species composition is important for the conservation of seasonally deciduous tropical forests, especially for the semi-arid Brazilian Caatinga. This study estimated that it takes more than 35 years for the forest to recover and return to a composition and structure similar to the original one. Therefore, management plans should restrict destructive uses before at least 35 years of regeneration have been reached.

Summary: The study conducted a floristic inventory of Fabaceae species in the Chapada do Araripe plateau in Brazil, listing a total of 194 species, 11 infraspecific taxa, and 81 genera. These numbers represent approximately 32% of the diversity of Fabaceae recorded in Brazil. The most diverse subfamilies were Caesalpinioideae and Papilionoideae, and the most representative genera were Senna, Chamaecrista, and Mimosa. The findings of the study have important implications for conservation strategies, ecological and phytosociological studies, and environmental education.

Summary: This study examined the taxonomic diversity of native angiosperms in the semiarid region of Ceara State, Brazil, with a focus on species found in Steppic Savanna. The results showed a high diversity of native angiosperms, including 120 families, 604 genera, and 1,443 species. Fabaceae was the most diverse family, and Croton (Euphorbiaceae) was the genus with the highest species richness. The Steppic Savanna species accounted for a significant proportion of all angiosperms in Ceara State and in Brazil as a whole.
