Monodominant tropical forests occur on several continents, including the Brazilian Amazon. In this study, we tested the hypothesis that seedling escape from leaf herbivory contributes to the maintenance of the monodominant Brosimum rubescens forest. The study was undertaken both in a monodominant forest of B. rubescens and in an adjacent seasonal f...

In this work we analyzed the population dynamics of Acacia tenuifolia in a seasonally dry forest on limestone outcrops in Central Brazil. We tested two hypotheses: (1) the population of this pioneer species shows accelerated dynamics; (2) the dynamics will be related to the environmental variables, due to edaphic stress (shallow and rock soils) and...

... A distribuição da comunidade arbórea dos indivíduos em classes diamétricas apresentou o padrão do J-invertido (Figura 5), ou seja, alta concentração de indivíduos nas classes menores e redução acentuada no sentido das classes maiores. Segundo Líbano;Felfili (2006) e Lima et al. (2003, a quase totalidade dos inventários de comunidades arbóreo-arbustivas de vegetação autóctones apresentam uma distribuição diamétrica seguindo o modelo do J-invertido (ou exponencial negativa), representando alta regeneração das espécies e distúrbios constantes (LÍBANO;FELFILI, 2006). ...
... No estudo de Moura (2008), desenvolvido na Mata de Galeria do Ribeirão do Gama, próximo à área deste trabalho, a sobrevivência aos dezesseis meses após o plantio foi de 72,7%. Pinto et al. (2007), ao recuperarem uma área degradada e invadida por Brachiaria spp., consideraram satisfatória a sobrevivência de 57% das mudas plantadas. ...
... Porém, clareiras abertas em Matas de Galerias facilitam a colonização de espécies exóticas invasoras em detrimento das espécies nativas do local. Espécies invasoras da família Poaceae e espécies do gênero Pteridium (samambaias) figuram entre as que mais frequentemente dificultam o estabelecimento de mudas de espécies arbóreas em projetos de restauração de Matas de Galeria no Distrito Federal (FELFILI et al., 2001). Martins et al. (2007) encontraram 28 espécies exóticas da família Poaceae colonizando projeto de restauração de fragmento de Cerrado no Distrito Federal. ...
... It dominates the terrestrial tropics, and covers approximately 20% of the global land surface, ranging from open grassland to densely canopied savanna with up to 80% tree cover (Parr et al., 2014). The Cerrado biome is a mosaic of grasslands, savannas and forests that covers nearly 2 million km 2 in Central Brazil (Mendonça et al., 2008). The grassland and savanna formations cover the largest portion of the biome, with a predominant herbaceous-shrub layer that harbors 80% of the Cerrado species (Amaral et al., 2017;Filgueiras, 2021). ...
... Studies comparing vegetation at different times can detect floristic and structural variations in populations and plant communities, supporting the understanding of factors that affect changes in these communities (e.g., Carvalho et al., 2010;Cavalcanti et al., 2009;Mews, Marimon, Pinto et al., 2011). In addition, these studies allow for inferences about vegetation dynamics; short-term assessments are more sensitive in detecting changes in a community (Braga & Rezende, 2007). ...
... Os espaçamentos de plantio apresentaram entre si alta similaridade na composição florística, levando-se em consideração que valores do índice de Sørensen são mencionados como altos quando maiores que 0,5 (Felfili et al., 1992). Machado et al. (2013) explicam que alta similaridade de espécies entre diferentes ambientes pode ser causado pela semelhança histórica e da proximidade das áreas. ...
... The Cerrado biome has the richest biodiversity among existing savannas and is considered an important "hotspot" for biodiversity conservation [49,50]. In Mato Grosso, the transition from the Brazilian Amazonia to Cerrado creates an overlap of both plant assemblages, resulting in high local biodiversity [51,52]. This high diversity of both fauna and flora suffers from the economic and demographic growth of the state [53], especially in Amazonia and the Amazonia-Cerrado transition zone [54][55][56]. ...
... Then, we calculated the weighted average (of height and diameter) of resprouts per plant (individual). From the diameter and height values of each resprout we calculated the aerial biomass using the Schumacher and Hall Model, which is the recommended model to estimate the biomass of trees with smaller diameters in savannas of the Cerrado (Rezende, Do Vale, Sanquetta, Figueiredo Filho, & Felfili, 2006). ...
... tomycorrhizal associations, on monodominance patterns(Arieira & Cunha, 2006; S. P. Ribeiro & Brown, 2006;Steenbock et al., 2011;Ibanez & Birnbaum, 2014;Kazmierczak et al., 2016;Marimon et al., 2016;Ebenye et al., 2017;Sansevero et al., 2017;Pivello et al., 2018;Steege et al., 2019), our results underscore the importance of taking into account factors that limit species dominance, particularlytemperature, over a broad geographical scale. Recently, Tovar et al. (2019) and Gris et al. (2020) pointed out the importance of precipitation for the maintenance of monodominant forests.Previously,Leathwick and Austin (2001) also demonstrated the influence of mean annual temperature on single-species Nothofagus dominance in New Zealand forests. ...
... The distinction between core and marginal zones has been assumed in most references to the Cerrado, although some studies have reported that floristic similarity between such zones does not support such classification [26,27] . Regarding the Cerrado fauna, most studies on birds [28][29][30][31][32] or other biological groups [33] have been carried out in the core Cerrado, as the remaining marginal areas are usually considered as relatively less representative of the Cerrado bird biodiversity [34][35][36] . As an example, Silva & Santos [37] proposed the removal of two bird species (Neothraupis fasciata and Cypsnagra hirundinacea) from the list of Figure 1. ...
