Nota sobre a ocorrência de Amasonia (Lamiaceae) nas restingas do Estado do Maranhão

Abstract

-The Amasonia genus (Lamiaceae, Ajugoideae) has around eight species and exclusively neotropical distribution. The present study aimed to discuss the recent occurrence of three species of Amasonia on the coast vegetation of Maranhão state, expanding the geographical distribution, and present diagnostic characters, comments and photographs. The records were based on collections carried out in the restingas of Itatinga beach and Sítio Aguahy, municipalities of Alcântara and São José de Ribamar, respectively. The species of A. arborea, A. calycina and A. campestris were recorded for the first time in Maranhão coast. This information reinforces the importance of floristic studies and the necessity of conservation of highly endangered restinga vegetation in Maranhão.

“…Cabe ressaltar que as espécies Amasonia arborea e Amasonia calycina, coletadas pela primeira vez na restinga de Itatinga, demonstram a importância dos estudos florísticos por ampliar o conhecimento e distribuição das espécies que até o momento não eram conhecidas ou registradas para o estado do Maranhão (Castro e Almeida Jr., 2016;Santos et al, 2016).…”

Population structure and reproductive indicators of the surubim Pseudoplatystoma punctifer (Siluriformes, Pimelodidae) in the São Miguel River, Amazon basin, Brazil

“…Therefore, the conservation of fish resources in natural environments becomes indispensable, as artisanal fishing communities depend on the development of public policies that seek the sustainability of fisheries management, based on an understanding of the balance between humans and natural resources, to prevent the depletion of native fish species (Doria et al, 2008). Thus, information on population features in fisheries production is important for estimating populations and their stocks, especially for species that are subject to fishing pressure and habitat destruction (Anderson et al, 2018;Pinaya et al, 2016;Santos et al, 2022). Despite the ecological and economic importance of the surubim, there are a few studies on its population dynamics and reproductive biology in the Amazon, limited to the studies conducted by Flores (2018) in the Peruvian Amazon and by Armas et al (2022) in the western Brazilian Amazon.…”
