“…Os outliers apresentado na região de confluências dos rios se assemelham com o levantamento de Ikeda-Castrillon, et al, (2011) que registraram essa espécie com maior valor de importância, considerada monodominante sobre a diversidade arbórea das ilhas do rio Paraguai na região que vai de Cáceres até a Estação Ecológica de Taiamã. Esses resultados podem estar relacionados a região da planície inundada que tem característica de possuir espécies monodominantes, como também a Erythrina fusca foi destacada por Olivo-Neto, et al, (2020), na região de planície na Estação Ecológica de Taiamã.…”

“…Isso demonstra que as espécies possuem suas particularidades na forma de ocorrência e distribuição, conforme foi relatado por alguns autores para áreas sob efeito de inundação (Olivo-Neto, et al, 2020;Pottker, et al, 2016) e que fatores bióticos e abióticos podem condicionar a presença ou ausência e uma maior ou menor abundância de espécies na região, sob efeito do pulso de inundação.…”

As matas ripárias estão presentes ao longo de cursos d'água, caracterizadas pela alta heterogeneidade ambiental. O objetivo desta pesquisa foi avaliar a diversidade florística da comunidade arbórea de mata ripária do rio Paraguai em áreas de planalto e Pantanal, em sua porção norte. Para coleta de dados foram implantados seis módulos com cinco parcelas disjuntas de 20 x 100m, totalizando um hectare em cada módulo. O nível de inclusão abrangeu os espécimes ≥ 5 cm de diâmetro medido a 1,30 m do solo e ≥ 3 m de altura. Foram amostrados seis hectares que abrigam 4.749 espécimes pertencentes a 52 famílias botânicas, 119 gêneros e 167 espécies. A riqueza foi significativamente maior no planalto e confluência dos rios, indicando regiões heterogêneas, expressando o contato com o ecótono de domínios fitogeográficos: Cerrado e Amazônia com regiões de encraves no Pantanal, diferindo da menor riqueza da planície, mas, ambas as áreas compreendem regiões de alto valor biológico e ecológico.

Although considered an evolutionary force responsible for shaping ecosystems and biodiversity, fires’ natural cycle is being altered by human activities, increasing the odds of destructive megafire events. Here, we show that forest type modulates the responses of terrestrial mammals, from species to assemblage level, to a catastrophic megafire in the Brazilian Pantanal. We unraveled that mammalian richness was higher 1 year after fire passage compared to a pre-fire condition, which can be attributed to habitat modification caused by wildfires, attracting herbivores and open-area tolerant species. We observed changes in assemblage composition between burned/unburned sites, but no difference in mammalian richness or relative abundance. However, by partitioning the effects of burned area proportion per forest type (monospecific vs. polyspecific), we detected differential responses of mammals at several levels of organization, with pronounced declines in species richness and relative abundance in monospecific forests. Eighty-six percent of the species presented moderate to strong negative effects on their relative abundance, with an overall strong negative effect for the entire assemblage. Wildfires are predicted to be more frequent with climate and land use change, and if events analogous to Pantanal-2020 become recurrent, they might trigger regional beta diversity change, benefitting open-area tolerant species.

“…The two types of forests presented above were separated in this analysis because they occupy different proportions of the TES area (PEF with 8% and MAF with 16%) (Frota et al 2020), and the E. fusca forests have a very irregular soil due to aerial roots. In addition, MAF can colonise areas that are seasonally flooded longer than PEF (Martins et al 2020;Olivo-Neto et al 2020).…”

Understanding the use of habitats by jaguars (Panthera onca) is fundamental to comprehend the ecological role of the species in the environments in which they occur. In Brazil, the Amazon and Pantanal biomes are considered fundamental for the conservation of the species. The Pantanal wetlands are in the centre of South America and the jaguar occupies about 47% of the territory. Poaching and habitat loss are the main threats to the population in this region. The highest densities of P. onca are found mainly in the north-central regions of Pantanal, where is situated the Taiamã Ecological Station (TES), a small federal protected area. The present study aims to elucidate fine-scale jaguar habitat selection in the TES region and check for seasonal differences. Through GPS collar information obtained from 11 animals, an analysis with the integrated step selection function (iSSF) was performed to investigate jaguar habitat selection. Our analysis indicated that these felines often use forested areas close to rivers, in contrast to open areas and away from watercourses. During the wet season, these cats tended to use forested areas more often than in the dry season. These data are important to support actions for the conservation of jaguars in the studied region.
