Two new critically endangered species of Vellozia (Velloziaceae) from the Campos Rupestres of Espinhaço Range, Brazil Renato A.

(en) Two new narrowly distributed species of Vellozia (Velloziaceae) are described, illustrated, and a preliminary status of conservation was assessed, Vellozia flavida Mello-Silva ex Magri and V. formosa Mello-Silva ex Magri. Both species occur in the municipality of Monte Azul, Minas Gerais State, Brazil, in the Campos Rupestres vegetation. Vellozia flavida is closely related to V. luteola and both are easily recognized by having yellow perianth, an uncommon character in the genus. Vellozia flavida however is distinguished by the high number of stamens (22) and the presence of capitate hypanthial emergences, whereas V. luteola has 15 stamens and subulate hypanthial emergences. Vellozia formosa is morphologically related to V. nanuzae, showing similar habits, however, it is distinguished by the leaf blades covered with long emergences on both surfaces vs. glabrous in V. nanuzae. Due to the narrow distribution of V. flavida and V. formosa and threats to their habitat such as mining and livestock industries, they were considered as critically endangered (CR) according to IUCN criteria.

Ultrastructural Biomarkers in Target Organs of Fish from Algeria Coastline to Access Water Quality Zina Bencheikh; Wahid Refes; Maritana Mela; C A Oliveira Ribeiro WATER AIR AND SOIL POLLUTION, v. 235, p. 387 2024 DOI Palavra-chave: Ultraestrutura celular; Mar Mediterrâneo; Biomonitoramento Ambiental; Biomarcadores de contaminação ambiental; Poluição Marinha Áreas do conhecimento: Ciências Biológicas; Ecologia; Ecologia Aplicada; Ecotoxicologia resumo ... The chemical degradation of aquatic ecosystems enforces a worst health condition to aquatic organisms leading to the development of diseases. This study was conducted to assess subcellular disturbs in liver and gill of marine fish species European pilchard (Sardina pilchardus), Round sardinella (Sardina aurita) and the European anchovy (Engraulis encrasicolus) from Algerian coastline in Mediterranean Sea: Algiers, BouIsmail and Zemmouri Bays. The ultrastructural alterations were determined by Transmission and Scanning Electron Microscopy. The damages described to hepatocytes include nuclear and cytoplasmic disturbs or even cell death as apoptosis and necrosis. The most evident effects were the chromatin condensation, deformed nuclear envelope, cytoplasmic vacuolization, occurrence of lipid droplets, organelle degradation and disturbs in Disse’s space organization or sinusoids. In gills the effects were the loss of lamellar pattern, wrinkled epithelium, mucus overproduction or epithelial cells damages in primary and secondary lamellas. The subcellular effects in hepatocytes help to understand the source of pathologies in fish species from Argelia coastline, and to evaluate the risk of exposure to complex mixture of chemicals. Also, the alterations found in hepatocytes and gills raise concerns about the long-term exposure to micropollutants. Finally, the results reveal the fragility of the species exposed along Algeria coastline and reinforce the needs to establish conservation politics and pollution control on the studied bays.
