In this study, we describe the structure of the interaction network between non-flying mammals and seven plant species with large fruits in a megadiverse savanna-forest mosaic in the Brazilian Cerrado. We also evaluated the individual contribution of each species to the organization of the interaction network and tested whether body mass determined the mammals’ role in the network. To record frugivory events of mammals with arboreal and terrestrial habits, camera traps were installed at ground and canopy levels. We identified 18 mammal species interacting with seven plant species in 515 frugivory events. Our observations highlight an interaction network with a modular and non-nested topology and the important role of large mammals in the network structure, which reflects the importance of the group in potential seed dispersal. The extinction of large frugivorous mammals can cause several damages to ecosystem services in the Brazilian Cerrado through changes in network structure, especially threatening the survival of plant species with large fruits.

We consider that changes in the hydrological regime of this floodplain can affect species richness, abundance and functional structure of waterbirds, wetland birds and non-wetland birds. Our study aimed to assess whether the degree of wetland dependence influences the response of bird groups to the flood pulse. We conducted the bird survey in the Paraguay River floodplain system, in five sampling sites, covering the periods of drought, flooding, full flood and ebb of the 2017-2018 hydrological cycle. Species richness and abundance were higher for non-wetland birds than waterbirds and wetland birds. On the other hand, we found that the higher the degree of wetland dependence by birds, the higher the differences in the functional-trait values. Species richness, abundance and all metrics of functional diversity varied significantly when there was an interaction between the degree of wetland dependence and the hydrological period. In all hydrological periods, bird groups occupied distinct niches. Traits such as foraging around or below the water surface were among the dominant functional traits in all hydrological periods. We emphasize the need to consider the functional traits of species in ecological studies of wetlands since measuring only species richness may not reflect the characteristics inherent to this type of ecosystem. In addition, the conservation of wetlands directly implies the maintenance of various niches throughout the hydrological periods, either for dependent or non-dependent bird species in wetlands.

The aim of this study was to evaluate community structure of birds in different macrohabitats of ATTZs from a protected area in the Pantanal wetland, Brazil. The survey of birds was carried out in three types of macrohabitats: Erythrina fusca Lour. monospecific forest, shrubland and pioneer polyespecific forest, and flooded grassland. The bird community living within the ATTZ varied according to macrohabitat type and period of the wetland landscape. We emphasise the importance of this protected area to biodiversity. Employ greater environmental control is required, since the region is not exempt from direct and indirect impacts derived from the Upper Paraguay River Basin.

Identified by its long wings and relatively short tail with dark violet-blue mantle and white belly and distal two-thirds of tail. Unmistakable due to long frontal crest, separated from the crown (Sick 1997), in addition to its distinctive call. Neothraupis fasciata (Lichtenstein, 1823) Described above.

One individual in eclipse plumage was seen foraging on a small mudflat on the shore of the Bracinho River. We identified this species by its brown upper, white belly and eyebrow, dark beak, and yellowish legs (Gwynne et al. 2010). We saw discreet spots on the belly, indicating its non-breeding status.

We observed this species in great flocks, foraging in the Flooded Grassland area. We observed a large number of foraging individuals in the EET and buffer zone. We identified this species by its square tail, dark blue upper, dirty white forehead and underneath, brown collar on the throat, face, and nape, and cinnamon upper tail (Ridgely and Tudor 2009).

Individuals were observed only in October 2016, when they were foraging with other scolopacids. This species was distinguished from all others on the mudflats by its white colour. This species was identified for by the grey upperparts, long slender bill, and white face, neck, and underparts (Erize et al. 2006).
