Molecular identification of sharks from the genus Sphyrna (Elasmobranchii: Chondrichthyes) in Maranh ão Coast (Brazil)
Braz J Biol. 2024 Mar 18;84:e274862. doi: 10.1590/1519-6984.274862. eCollection 2024.ABSTRACTSharks of the genus Sphyrna are under intense exploitation globally. In Brazil's northern coast, this genus represents a high proportion of fisheries landings and comprises four species. However, due to difficulty of specific identification when specimens are landed, most of the records are limited to the genus level. Here we analyzed the effectiveness of ITS2 (Internal Transcribed Spacer 2 of rDNA) fragment length protocol (Abercrombie et al., 2005) for identifying hammerhead shark species, comparing with the analysis of COI (Cyto...

Arbuscular mycorrhizal fungi, phosphorus and organic residues in Peltophorum dubium (Spreng.) Taub. seedlings
This study aimed to evaluate the impact of organic residues, inoculation with AMF, and phosphorus on the growth and quality of Peltophorum dubium (Spreng.) Taub. seedlings. Two independent experiments were conducted. In Experiment I, treatments included inoculation with various AMF species: control (without inoculation), Clareoideoglomus etunicatum, Rhizophagus heterosporum, Rhizophagus clarum, and MIX (a combination of the three AMF species), all in conjunction with varying doses of phosphorus (0, 60, 120, 180, and 240 mg kg-1 soil). In Experiment II, treatments comprised a control group (without AMF) and inoculation with...

Phytochemical analysis, toxicity and evaluation of antioxidant and antimicrobial activities of leaves of Dipteryx alata Vogel
In this study, our objective was to conduct a comprehensive phytochemical analysis, determine toxicity levels, and assess the antioxidant and antimicrobial properties of extracts derived from the leaves of Dipteryx alata Vogel, a native species of the Brazilian cerrado flora. Three distinct extracts were prepared utilizing assisted ultrasound and the Soxhlet apparatus, namely, Ultrasound Crude Extract (UCE), Soxhlet Crude Extract (SCE), and the Soxhlet Ethanol Extract (SEE). The phytochemical analysis revealed the presence of flavonoids, tannins, phytosterols, and saponins in all extracts. Additionally, alkaloids were spec...

Designing a community-supported agriculture model for increasing food security
Braz J Biol. 2024 Mar 18;84:e278045. doi: 10.1590/1519-6984.278045. eCollection 2024.ABSTRACTThe institutionalization of participation is a topic that has been discussed in different ways over the last few decades. There are many diverse aspects of the agricultural sector and rural communities that can be identified and used to bring about a major change in agriculture. Community supported agriculture (CSA) is one of the participatory and sustainable approaches that can be used in this regard. CSA is a relatively new socioeconomic model for producing food materials, increasing food security, improving the quality of food m...

Features of the choice of potato (Solanum tuberosum) varieties when growing two harvests in the temperate zone of Russia
Braz J Biol. 2024 Mar 18;84:e278272. doi: 10.1590/1519-6984.278272. eCollection 2024.ABSTRACTThe development of potato plants during the cultivation of two crops occurs in a short period. At the same time, field conditions change and do not repeat over time. The formation of the crop during the cultivation of two crops in the Moscow region turns out to be in different growing conditions: the first crop falls on a long day and moderate temperatures, as well as sometimes returning frosts, the second crop falls on a short day and high temperatures, as well as a lack of moisture. The purpose of our research was to substantiate...
