First record of Hister cavifrons Marseul, 1854 (Coleoptera: Histeridae) for Santa Catarina's Island, Brazil VARELA, MARIA E. S.; HESSELN, SOL G.; Fernando Willyan Trevisan Leivas; PINTO, CARLOS J. C.

(en) Hister cavifrons Marseul, 1854 (Coleoptera: Histeridae) is a common species in Brazilian territory mostly associated with animal carcasses that has previously been recorded in the Amazon, Atlantic Forest, and Cerrado biomes across several Brazilian states, ranging from the North to the South of the country. The highest number of records is from the state of Paraná, while Santa Catarina has only two records from inland municipalities. This note presents the first record of H. cavifrons on the coast of Santa Catarina specifically in the municipality of Florianópolis and the third for the state. The species was sampled in Biguá [Nannopterum brasilianum (Gmelin, 1789) (Suliformes: Phalacrocoracidae)] carcass, an aquatic bird commonly found along the Santa Catarina coast, marking the first record of this species associated with this animal, during the month of April (autumn season).

Marine brachyuran crabs? osmoregulatory and metabolic responses upon warming and seawater dilution challenges: the non-native Charybdis helleri is more sensitive than the native Menippe nodifrons RIOS, LEONARDO P.; Carolina Arruda de Oliveira Freire BIOLOGICAL INVASIONS, v. 28, n. 1, p. 28 2026 DOI Home page Palavra-chave: crab; osmoregulation; metabolismo; Oxygen consumption; Ammonia; lactate Áreas do conhecimento: Ciências Biológicas; Fisiologia; Fisiologia Comparada; Fisiologia Comparativa da Osmorregulação resumo ... Non-native organisms challenge ecosystems, especially under the additional influence of climate change. Comparisons of physiological performance between ecologically-similar native and non-native species contribute to the field of invasion biology. We examined two decapod crustaceans that occur sympatrically in the Estuarine Complex of Paranaguá (ECP), Brazil: Charybdis helleri (non-native) and Menippe nodifrons (native). Crabs were acclimated to control (26 °C) and elevated (30 °C) temperatures for one week in full-strength seawater (35‰), and were then submitted to dilute seawater (30, 25, and 20‰) for 6 h, simulating short-term tidal challenges. Hemolymph was assayed for osmolality, chloride, magnesium, and lactate; muscle samples were evaluated for hydration levels. Dissolved oxygen and ammonia production were assessed in the experimental water. Both species were impacted by low salinity, with a synergistic effect from elevated temperatures. However, C. hellerii was more affected by the combined treatments, displaying less capacity to keep stable muscle hydration levels upon seawater dilution, a steeper decrease in dissolved oxygen, higher ammonia excretion, and higher lactate. The non-native C. hellerii was physiologically challenged to a much higher degree than the native species. Although C. hellerii has established populations in the ECP, its sensitivity to salinity reductions and rising temperatures may limit its further spread in areas with intense fluctuating abiotic conditions. These data can support modelling efforts of the trends in species distribution where C. helleri is invasive. This unexpected result may also be indicative of the ongoing process of invasion; similar approaches could contribute to invasion science involving other marine/estuarine invertebrates.

Ruellia capixaba (Acanthaceae, Acanthoideae), a new scandent species from Espírito Santo state, with taxonomic updates for other Ruellia of the Atlantic Forest of Brazil Danilo A. Zavatin; Joelcio Freitas; LIRIO, ELTON J.; Vagner Schaefer Faller; Jefferson Prado; Cíntia Kameyama; Ulisses G.

Ruellia is the second most species-rich genus in the family Acanthaceae, comprising approximately 375 species that are primarily distributed in tropical and subtropical regions. In Brazil, 104 species of the genus are recorded, occurring across all biomes. The Atlantic Forest, recognized as a biodiversity hotspot, harbors 24 species of Ruellia, despite ongoing threats such as deforestation. In this paper, we describe and illustrate the new species Ruellia capixaba, endemic to the Atlantic Forest in Espírito Santo State, Brazil. We also propose a new name, Ruellia fatimae, for a red-flowered, scandent species transferred from the genus Stephanophysum, lectotypify Ruellia furcata, another species endemic to this biome, and provide an identification key to the scandent species of Ruellia occurring in the Brazilian Atlantic Forest.
