Fig. 2.—Majority rule consensus tree obtained in the Bayesian analysis of 45 Cytochrome b gene sequences of specimens of Akodon. Numbers indicate posterior probability (left) and ultrafast bootstrap (right) support values of the adjacent nodes. A "<" indicates that a given clade gathered less than 50% of ultrafast bootstrap. A "-" indicates that a given clade was not recovered in the maximum likelihood analysis. Each terminal is labeled with the species name and GenBank accession number. Species groups of Akodon are delimited with bars on the right side of the tree (see also Jayat et al. 2010; Coyner et al. 2013).

High avian species richness in a minute Cerrado remnant in southeastern Brazil

Antonelli, Victor Rodrigues. Departamento de Ciência Florestal, Solos e Ambiente, Universidade Estadual Paulista. e-mail: victor.r.antonelli@unesp.br Supplementary material. Supplementary material 1. Location of the Botucatu State Forest, southeastern Brazil. Supplementary material 2. Published references on the birds of Botucatu, southeastern Brazil. Supplementary material 3. Bird species observed at Botucatu State Forest (FEB), Pond adjacent to FEB (LAFEB), and Cabocla pond (LC), southeastern Brazil. The primary list (1) represents documented (photograph, sound recording, museum specimen) species; the secondary list (2) includes species that lack documentation but are certainly found in the areas; in the tertiary list (3) are species whose range or identification demand proper documentation to be included in the areas. Habitats include: Aq. = Aquatic, DG = Dry grassland, Fly = Flyover, GF = Gallery forest, WG = Wet grassland. Migration status are: MGT = migratory, MPR = partially migratory, ND = not defined. Threat status at state (SP), national (BR) and global (IUCN) levels: CR = Critically Endangered, EN = Endangered, VU = Vulnerable; NT = Near Threatened. Sources stand for A = this study, C = Ciambelli (2008), E = eBird, R = Risso (2023), W = Wikiaves, * = Cerrado endemic species (Silva 1995, Silva and Santos 2005). Taxonomy follows the Brazilian Ornithological Records Committee (Pacheco et al. 2021). Supplementary material 4. Results of Bayesian Logistic Regression for 15 Cerrado remnants in São Paulo state, southeastern Brazil. Supplementary material 5. Noteworthy records.

Native ants help to spread an invasive African grass in the Cerrado

Plant-animal interactions may facilitate biological invasions. The African grass Urochloa decumbens is an aggressive invader in the Cerrado. We demonstrate that native ants are dispersing the seeds to short distances, allowing the gradual spread of the invasive to sites without the need of great anthropogenic soil disturbances.
