    Abstract The crab-eating fox (Cerdocyon thous) and the Pampas fox (Lycalopex gymnocercus) are two canids with very similar food and habitat requirements, which live in sympatry across parts of their distributions. Here we describe the diet and habitat use of both canids in the Pampas biome. The study took place in southern Brazil from December 2012 to December 2013. Diet and habitat use analyses were based on fecal samples, footprints and direct visualizations. Diet overlap was measured using Pianka’s index, while habitat use was measured using presence records from three different environments; forests, edges and open areas. Both canids feed on invertebrates and vertebrates but have preferences for fruits, especially Syagrus romanzoffiana. Pianka’s index showed a high overlap of their diets throughout the year, with the exception of autumn. Regarding habitat use, C  . thous preferred to inhabit forested areas while L. gymnocercus was more active in open areas. Our results showed that fruits were the most consumed food item in the Pampas biome. Our findings suggest that habitat use by these two canids is affected by seasonal variation in fruit abundance, but other factors, such as parental care, should be taken into account when explaining how they behave throughout the year.

    Abstract We present the results of a three-year study on the bat species killed by wind turbines at the Osório Wind Farm, a large wind power complex in southern Brazil, and compare these fatalities to the composition of the local bat fauna. Fatality searches around wind turbines were conducted from 2006 to 2009, as well as a bat inventory through mist-netting and searches for colonies from 2004 to 2010. We found a total of 336 bat fatalities: Tadarida brasiliensis (n = 245), Lasiurus cinereus (n = 44), Nyctinomops laticaudatus (n = 12), Molossus molossus (n = 9), Lasiurus blossevillii (n = 6), Promops nasutus (n = 3), Lasiurus ega (n = 3), Molossus rufus (n = 1), and Artibeus lituratus (n = 1). By mist-netting, we recorded 13 bat species in the region, of which only six were killed by wind turbines. Our results are similar to mortality patterns from the Northern Hemisphere in terms of: (1) uneven distribution of fatalities among species; (2) dominance of migratory species, including foliage/tree-roosting bats; and (3) discrepancy between presence and abundance of species recorded in the wind farm area and in the fatality sample.

    Abstract Flowering plant species and their nectar‐feeding vertebrates exemplify some of the most remarkable biotic interactions in the Neotropics. In the Brazilian Atlantic Forest, several species of birds (especially hummingbirds), bats, and non‐flying mammals, as well as one lizard feed on nectar, often act as pollinators and contribute to seed output of flowering plants. We present a dataset containing information on flowering plants visited by nectar‐feeding vertebrates and sampled at 166 localities in the Brazilian Atlantic Forest. This dataset provides information on 1902 unique interactions among 515 species of flowering plants and 129 species of potential vertebrate pollinators and the patterns of species diversity across latitudes. All plant–vertebrate interactions compiled were recorded through direct observations of visits, and no inferences of pollinators based on floral syndromes were included. We also provide information on the most common plant traits used to understand the interactions between flowers and nectar‐feeding vertebrates: plant growth form, corolla length, rate of nectar production per hour in bagged flowers, nectar concentration, flower color and shape, time of anthesis, presence or absence of perceptible fragrance by human, and flowering phenology as well as the plant’s threat status by International Union for Conservation of Nature (IUCN) classification. For the vertebrates, status of threat by IUCN classification, body mass, bill or rostrum size are provided. Information on the frequency of visits and pollen deposition on the vertebrate’s body is provided from the original source when available. The highest number of unique interactions is recorded for birds (1771) followed by bats (110). For plants, Bromeliaceae contains the highest number of unique interactions (606), followed by Fabaceae (242) and Gesneriaceae (104). It is evident that there was geographical bias of the studies throughout the southeast of the Brazilian Atlantic Forest and that most effort was directed to flower–hummingbird interactions. However, it reflects a worldwide tendency of more plants interacting with birds compared with other vertebrate species. The lack of similar protocols among studies to collect basic data limits the comparisons among areas and generalizations. Nevertheless, this dataset represents a notable effort to organize and highlight the importance of vertebrate pollinators in this hotspot of biodiversity on Earth and represents the data currently available.

    Abstract A survey of the Streblidae batflies on the phyllostomid bats was conducted in the northeastern Rio Grande do Sul State, Brazil, during 1997. Hundred thirty three streblids were collected on 44 parasited hosts. Eleven species of batflies (Trichobius dugesii Townsend, 1891, T. tiptoni Wenzel, 1976, Trichobius sp., Paratrichobius longicrus (Miranda Ribeiro, 1907), Megistopoda aranea (Coquillett, 1899), M. proxima (Séguy, 1926), Exastinion clovisi (Pessoa & Guimarães, 1936), Paraeuctenodes longipes Pessoa & Guimarães, 1936, Anastrebla modestini Wenzel, 1966, A. caudiferae Wenzel, 1976 and Metelasmus pseudopterus Coquillett, 1907) were found on six species of phyllostomid bats (Artibeus lituratus (Olfers, 1818), A. fimbriatus Gray, 1838, Sturnira lilium (E. Geoffroy, 1810), Glossophaga soricina (Pallas, 1766), Anoura caudifera (E. Geoffroy, 1818) and A. geoffroyi Gray, 1838). All records are new for the Rio Grande do Sul and Anastrebla caudiferae is firstly recorded in Brazil. Differences in the batflies community composition in Artibeus fimbriatus and A. lituratus are discussed.

    Abstract Ecological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers of SRS are expected to coincide geographically with a high degree of community-level ecological specialization, but this suggestion remains poorly supported with empirical evidence. Here, we analysed data for hummingbird resource specialization, range size, contemporary climate, and Late Quaternary climate stability for 46 hummingbird-plant mutualistic networks distributed across the Americas, representing 130 hummingbird species (ca 40% of all hummingbird species). We demonstrate a positive relationship between the proportion of SRS of hummingbirds and community-level specialization, i.e. the division of the floral niche among coexisting hummingbird species. This relationship remained strong even when accounting for climate, furthermore, the effect of SRS on specialization was far stronger than the effect of specialization on SRS, suggesting that climate largely influences specialization through species' range-size dynamics. Irrespective of the exact mechanism involved, our results indicate that communities consisting of higher proportions of SRS may be vulnerable to disturbance not only because of their small geographical ranges, but also because of their high degree of specialization.
