“…The relevance of Fabaceae has been common as the richest in surveys carried out in SSF (Silva et al, 2004;Imaña-Encinas et al 2008;Prado Júnior et al, 2010;Dan et al, 2010;Lisboa et al, 2019). This expressiveness also occurs in other forest and savanna formations in Cerrado, in Goiás state, as already noted in cerrado sensu stricto (Silva et al, 2019), rocky outcrops in Cerrado (Leles & Diniz, 2017), woody savanna or 'cerradão' (Guilherme et al, 2020), riparian forest (Ferreira et al, 2020) and deciduous dry forest (Andriani et al, 2020). This predominance of the family in studies of tree structures in natural ecosystems is attributed to the efficiency in nitrogen fixation (Françoso et al, 2016), and yet many species have mutualistic relationships, such as mycorrhizae (Abreu et al, 2018).…”

In Goiás, seasonal forests structure studies are scarce, especially in fragments located in legal reserves, subject to human disturbances. Therefore, the study aimed to perform the phytosociology of a fragment of a rural property, in a seasonal semideciduous forest. We evaluated structure, richness, diversity, dispersion mechanisms, ecological groups, and species distribution patterns found in the study and floristic links between Cerrado, Amazon and Atlantic Forest. In a one-hectare sample plot, all live trees with a diameter at breast height ≥ 10 cm were measured. The values of density and basal area were 561 ind.ha-1 and 26.2 m².ha-1, respectively. We recorded 37 species with diversity indices (H’) of 2.36 and evenness (J’) of 0.65. Toulicia reticulata, Chaetocarpus echinocarpus, Bocageopsis mattogrossensis and Nectandra cuspidata were species with the highest importance value, corresponding to 69% and 65% of all density and basal area, respectively. Fabaceae obtained the highest floristic richness, with six species, although it was little represented in terms of abundance. Our results suggest that the fragment is a mature forest in good conservation status. This is reinforced by the high size of trees, in addition to the predominance of zoochoric (83.8%) and secondary (92.1%) individuals in the survey.

“…According to Machado et al (2015) [10], the Morros Garapenses EPA is in a transition zone between the northern Cerrado of Maranhão and Mata de Cocais, providing the EPA with a diversity of physiognomies, high species richness, and high potential for new occurrences [79]. Transition areas present heterogeneous vegetation influenced by factors that act on them, such as soil texture and fertility, slope, elevation, and ground water mining [80,81].…”

The Morros Garapenses Environmental Protection Area (EPA) is home to significant biodiversity and an important paleobotanical site, with Permian fossil records, being a strategic area for studies in Maranhão. The objective of this study was to provide a list of species of phanerogams from the Morros Garapenses EPA. The material was collected through the walking method on pre-existing trails at different elevations and phytophysiognomies. The collection, herborization, identification, and classification of species followed the usual methodology for this type of research. A total of 297 species distributed in 196 genera and 70 families were cataloged. The families with highest specific richness were Fabaceae (60 species), Malvaceae (20 spp.), Rubiaceae (18 spp.), Cyperaceae (16 spp.), Euphorbiacae (14 spp.), and Bignoniaceae (13 spp.). Forty-nine species were endemic to Brazil, fifteen are being reported for the first time from Maranhão, and five from Cerrado. Several phytophysiognomies were found in the area, namely, Cerradão (33 species), Campo sujo (7 spp.), typical Cerrado (154 spp.), veredas (10 spp.), riparian forest (5 spp.), and anthropized areas (5 spp.). The study revealed a significant number of species in the Morros Garapenses EPA, stressing the urgent need to create a management plan for the sustainable use of natural resources and recovery of degraded areas.

“…The families with the largest species number in the whole survey were Fabaceae (8 species), followed by Myrtaceae (5), Anacardiaceae (3) and Moraceae (3). Myrtaceae and especially Fabaceae, in general, have the greatest richness in surveys not only of semideciduous forests (GUILHERME; NAKAJIMA, 2007), but other forest formations in the Brazilian Cerrado (ANDRIANI et al, 2020;FERREIRA et al, 2020;MARTINS et al, 2020).…”

Estudos comparativos entre diferentes estratos de florestas em sucessão ecológica são importantes para entender a dinâmica florestal. O estudo avaliou aspectos florísticos, fitossociológicos e ecológicos entre os estratos adulto e regenerante de um fragmento urbano de floresta estacional semidecidual, em Jataí, Goiás. Nas últimas décadas, a vegetação que era tipicamente savânica tem se tornado uma floresta. As árvores adultas (diâmetro a altura do peito, DAP ≥ 5 cm) foram amostradas em 12 parcelas permanentes de 200m². Em cada uma delas, sub-parcelas de 25m² foram amostradas para o estrato regenerante, que compreendeu indivíduos com DAP 5cm e altura ≥ 1m. Regenerantes tiveram maior riqueza (31 espécies), com duas espécies a mais do que os adultos. Houve baixa similaridade florística e estrutural entre os estratos, indicando uma substituição de espécies ao longo do tempo. A diversidade de Shannon foi significativamente menor para o estrato arbóreo (teste t), visto que apresentou baixa equabilidade, com dominância ecológica de poucas espécies. Ambos os estratos tiveram elevada proporção de espécies pioneiras, quando comparado com outros estudos. Zoocoria e espécies de ambientes florestais foram expressivamente mais abundantes no estrato regenerante. O estudo revelou um fragmento em franco processo de sucessão secundária e vulnerabilidade diante de pressões antrópicas, sendo importante os cuidados quanto à sua conservação.
