“…This reserve plays an important role as a resting and breeding site for seabirds (Branco 2003a(Branco , 2004Vooren and Brusque 1999;Efe et al 2000;Branco 2004). Also, it has suitable habitats for terrestrial species since two of the islands are covered by a well-preserved Atlantic Forest (Salvador et al 2009).…”

The Arvoredo Marine Biological Reserve (RBMA) is a protected area in southern Brazil created in 1990 to safeguard the marine biodiversity of the Arvoredo Archipelago. There are only few studies about bird assemblage in most of the Brazilian coastal islands, including this protected area. Therefore, this paper presents the first complete list of birds for RBMA based on data from literature and surveys between 1986 and 2012 on islands and surrounding waters. Birds were recorded during captures using mist-nets and opportunistic observations on land in January 2012, as well as in monthly strip-transects and sectors on sea between 2010 and 2012. The present list includes 84 species (15 captured) from primary data and 22 species from other sources, totaling 106 species from 37 families. Bird assemblage in the RBMA is composed by 44 aquatic birds and 62 landbirds, whereas 13 are endemic to the Atlantic Forest and 12 are threatened. As expected due to the diversity of habitats, Arvoredo and Galé Islands supported the richest assemblages in the RBMA. The number of species in the whole RBMA is smaller than bigger islands elsewhere in the Atlantic Forest domain, but similar to same-sized and same-habitat ones. Our results highlight the importance of this reserve as a suitable and isolated habitat to forest species. Deserta Island is an important site for nesting, resting, and foraging seabirds.

: Faunal impoverishment and distorted species compositions are common phenomena in oceanic islands; however, many land-bridge islands are poorly inventoried, especially in the Neotropics. We sampled a small mammal community on a land-bridge island (Anchieta Island) along the Brazilian coast. We found only one marsupial Didelphis aurita (Wied-Neuwied, 1826) and two rodent species Oligoryzomys nigripes (Olfers, 1818) and Trinomys iheringi (Thomas, 1911) during 12 months of live trapping and 9195 trap-nights. The diversity of rodents and marsupials was not explained by species-area relations, indicating possible past extinctions. The abundance of D. aurita and O. nigripes was approximately three times higher, while the abundance of T. iheringi was approximately four times lower than abundances reported from other Brazilian Atlantic Forest sites. The population of D. aurita exhibited many phenotypic changes; males were on average 8 % smaller and females produced 30 % less litters than those from the mainland and other land-bridge islands. The long history of forest disturbance, habitat loss, reduction in forest productivity, and the recent introduction of mesopredators may be the major drivers that explain the small mammal community composition on this island.
