Floristic analysis and dispersal syndromes of woody species of the Serra de Maracaju, Mato Grosso do Sul, Brazil

Abstract

This paper presents a floristic survey of the wood component of cerrado s.s. (eastern face) and gallery forest (western face) areas carried out in the southern part of the Serra de Maracaju. The dispersal syndromes and floristic relations of this portion of the Serra were compared to those of other formations from different regions of Brazil. Between October 2007 and September 2008, monthly collections identified 144 species. As for dispersal syndromes, zoochory prevails, followed by autochory and anemochory. The gallery forest is a heterogeneous formation that shelters floristic elements shared with the Atlantic rain forest, the Amazonian forest, semi-deciduous seasonal forests and dry forests of the Pantanal. Low similarity between the two areas analyzed makes this region unique and suggests that the Serra de Maracaju is greatly influenced by the semi-deciduous seasonal forests of the southeastern region.

Floristics and Reproductive Phenology of Trees and Bushes in Central West Brazil

“…The present study showed that Fabaceae also prevails in environments with different, albeit close, formations, as observed by Gentry (1993) in neotropical environments. Malvaceae, the third most representative family in this study, is also reported among the main families occurring in the Serra de Maracaju in other localities (Ramos and Sartori 2013), while, according to Heywood et al (2007), this family is common in savanna, "scrub" and forest edges. Grouping 1 (A1) corresponds to a remnant of seasonal deciduous forest characterized by the occurrence of the same species, significant levels of leaf deciduousness in the dry period, according to field observations, and eutrophic soil.…”

“…Damasceno-Júnior, unpublished data, B.G. Fina, unpublished data, Ramos andSartori 2013). More recent rugged landscapes are usually richer in given soil elements, which can favor the settlement of different, albeit geographically close plants (Reatto et al 2008).…”

“…Although the southern part of this Serra has rugged landscapes and steep hillsides with different altitudes, phytophysiognomies, and floristic compositions, it has been scarcely studied (B.G. Fina, unpublished data, Ramos and Sartori 2013) and no work has conjointly addressed its floristic and phenological aspects.…”

First record of the Hauxwell’s Thrush, Turdus hauxwelli Lawrence, 1869 (Aves: Turdidae) from Mato Grosso do Sul, Brazil, and geographic range extension

“…1) , we mistnetted an individual of T. hauxwelli. The local vegetation is a fragment of Cerradão (semi-deciduous forest), a phytophysiognomy of Cerrado, in this case with various influences of Amazonian, Atlantic and Chaco forests (Damasceno et al 2000, Ramos andSartori 2013). The study site is located in the central portion of the Serra de Maracajú, a geological formation made of sedimentary and volcanic rocks.…”

Liana species composition differs, in spite of trait similarities, in two adjacent forest types in Central Brazil

“…The Southern part of the mountain range is rugged with steep hills, harboring several phytophysiognomies of varying floristic composition, which may allow interconnections between seasonal forests and other vegetation types. Previous research in the region (Ramos & Sartori, 2013;Assunção, Casagrande, & Sartori, 2014) did not include climbing species. High rates of deforestation in the mountain range contribute to a lack of information on the flora and its biogeographical affinities.…”
