“…Apart from the main drivers mentioned, there has been a notable increase in mining activities and, to a lesser extent, aquaculture. While aquaculture is predominantly associated with aquatic environments (Franco et al 2018), inland aquaculture occasionally requires the creation of terrestrial ponds (Boyd & Gross 2000), resulting in habitat loss, as evidenced during a field visit to a significant forested area at the northern limit of the Bradypus torquatus distribution. Despite the expansion of these activities, the total area occupied in both ranges remains relatively small (<1%).…”

The first step towards understanding the conservation situation and informing conservation decision‐making is to identify the habitat loss drivers. However, for nearly all tropical biota, there is a glaring lack of information on the spatiotemporal patterns of anthropogenic drivers. Our objective was to analyse the spatial and temporal distribution of the main anthropogenic drivers of habitat loss for Bradypus torquatus and Bradypus crinitus, two endangered and endemic species to the Brazilian Atlantic Forest. We used land‐use information associated with seven major IUCN‐based threats to sloths, covering a three‐generation time window (1988–2020), to quantify the current area occupied, temporal changes, heterogeneity, and intensity of drivers across species distributions. We found that cattle farming and ranching dominate the range of both species (from 49% to 56%) and cover an area larger than the remaining native forest. Other drivers also represent important spatial and temporal features of land conversion across species distributions. Driven mainly by livestock expansion, both sloth species have experienced a significant loss of forest cover (Bradypus torquatus – 659098.70 ha; Bradypus crinitus – 139013.20 ha) in the Brazilian Atlantic forest. Overall, Bradypus torquatus showed a higher rate of deforestation than forest regeneration, whereas forest gains outweighed habitat loss for Bradypus crinitus. Our results show that a substantial area of native forest – essential for strictly arboreal species – is being continuously replaced by cattle ranching and agricultural activities, which may lead to population isolation and decline, threatening the long‐term population viability.

“…O sistema produtivo adotado poderá gerar maiores ou menores interferências ambientais, conforme sua concepção. Os resíduos gerados na criação, constituídos por alimentos não ingeridos e produtos do metabolismo dos peixes, liberados no ambiente aquático, aumentam principalmente a concentração de nitrogênio e de fósforo na água [6]. Dentre os compostos nitrogenados presentes na água, encontra-se a amônia, quando sua concentração aumenta, a excreção deste metabólito nos organismos aquáticos diminui.…”

Este trabalho teve como objetivo avaliar e validar uma metodologia para obtenção indireta de concentração de amônia em aquaponia com o uso de sensores, software, e hardware baseados na plataforma Arduino. Os resultados parciais apontam para a hipótese de que existe uma correlação positiva dos dados coletados e similaridade na construção das curvas de regressão polinomial para as duas variáveis analisadas, porém, mais informações e mais estudos são necessários para poder afirmar que a metodologia proposta é confiável.
