Decomposition, topology, properties, and graphs of woody crown networks of 15 tree species of Cerrado vegetation
<p>Data of decomposition, topology, properties, and the corresponding graphs of 15 adult tree species of Cerrado vegetation, <em>sensu stricto</em> physiognomy. The woody crown networks (WCN) representations in a bidimensional space were obtained by drawing followed the methodology described by Prado et al. (2020, Prado, C.H.B.A., Trovão, D.M.B.M., Souza, J.P.<strong>,</strong> 2020. A network model for determining the woody crown's decomposition, topology, and properties. Journal of Theoretical Biology, v. 499, p. 110318. https://doi.org/<a href="https://www.x-mol.com/paperRedirect/1258515479077781504">10.1016/j.jtbi.2020.110318</a>.). The branching regions were the nodes, and the woody crown segments connecting the nodes or merely emerging from them were the connectors. Those trees grew under natural conditions in a most common (<em>sensu stricto</em>) physiognomy of Cerrado vegetation, in a reservoir of 86 ha, located at 850 m above sea level in São Carlos city, São Paulo state, Brazil, at 21°58'- 22°00'S and 47°51'-47°52'W. Following the Köppen climatic classification, this region is between Aw and Cwa, a tropical climate with dry winter and wet summer. The rainy season occurs between October-March, and the dry season between April and September. </p>
Behavior preferences between medium-large mammals in Atlantic Forest and Cerrado inside a public university of Southeastern Brazil
<p>We studied large and medium-sized mammals in a modified landscape between the Atlantic Forest and a Cerrado transitional zone (Brazil). We used eight camera traps between August 2016 and August 2017, totaling 75840 camera hours or 3,160 camera trap days. The sampling effort was evaluated from a rarefaction curve based on the daily sampling. We conducted comparative univariate and multivariate ordination statistical analyses. We recorded 19 species in 13 families. The most recorded species were S. scrofa and Cerdocyon thous , while the least recorded were Cuniculus paca, Didelphis albiventris and Tamandua tetradactyla. Richness and total records do not differ among day period, month, season, vegetation type, and moon phase. Individually, species abundance nevertheless sometimes showed trends for these factors. S. scrofa dominated all landscapes and periods of the year because it is an opportunist species that rapidly reproduces and lacks natural efficient predators. The presence of this species reduces the dissimilarity of the community, but when it is removed, the dissimilarity of native species increases. The modified landscape studied here is an important area for mammalian fauna owing to high richness; some species in the area are threatened with extinction. The wide temporal sampling effort contributed to a high number of mammal species records, although without spatial variation.</p>
