“…Altogether, we compiled data on 1,831 species occurring in 1,953 sampling sites, totalling nearly 59,000 species occurrence records (Figure ). The data were collected between years 1990 and 2017, during which the geographical coordinates are of required accuracy (Bovendorp et al, ; Culot et al, ; Hasui et al, ; Lima et al, ; de Lima et al, ; Muylaert et al, ). A list of the filtered tree data sources is found in Appendix , Table .…”

Aim: Forest fragmentation is among the principal causes of global biodiversity loss, yet how it affects mutualistic interactions between plants and animals at large spatial scale is poorly understood. In particular, tropical forest regeneration depends on animal-mediated seed dispersal, but the seed-dispersing animals face rapid decline due to forest fragmentation and defaunation. Here, we assess how fragmentation influences the pairwise interactions between 407 seed disperser and 1,424 tree species in a highly fragmented biodiversity hotspot.Location: Atlantic Forest, South America. Methods:We predicted interaction networks in 912 sites covering the entire biome by combining verified interaction data with co-occurrence probabilities obtained from a spatially explicit joint species distribution model. We identified keystone seed dispersers by computing a species-specific keystone index and by selecting those species belonging to the top 5% quantile. Results:We show that forest fragmentation affects seed dispersal interactions negatively, and the decreased area of functionally connected forest, rather than increased edge effects, is the main driver behind the loss of interactions. Both the seed disperser availability for the local tree communities and in particular the proportion of interactions provided by keystone seed dispersers decline with increasing degree of fragmentation. Importantly, just 21 keystone species provided >40% of all interactions. The numbers of interactions provided by keystone and non-keystone species, however, were equally negatively affected by fragmentation, suggesting that seed dispersal interactions may not be rewired under strong fragmentation effects. Conclusions:We highlight the importance of understanding the fragmentation-induced compositional shifts in seed disperser communities as they may lead to lagged | 155 MARJAKANGAS et Al.

“…The current native mammal fauna on the Anchieta Island was quite impoverished due to its isolated location, as well as past human impact (Bovendorp and Galetti, 2007, Souza et al , 2019, Supporting information S1). There are no previous studies about the occurrence and/or diet of common vampire bats on the island in the beginning of the last century (Garbino et al , 2016, Muylaert et al , 2017). However, previous information on human occupation on island (Guillaumon et al , 1989) and record of common vampire bats in the mainland and island nearby Anchieta (Garbino et al , 2016), led us to believe that domestic animals present there (especially cattle, pigs and dogs) were the main prey and responsible for maintaining a viable population of the species on island.…”

The proliferation of native, alien, invasive and domestic species provide novel and abundant food resources for the common vampire bat (Desmodus rotundus) that could alter its prey preference. Based on the analysis of carbon and nitrogen stable isotopes, we report the prey choice of D. rotundus on introduced mammals in an tropical land-bridge island where the domestic animals were removed and 100 individuals of 15 mammal species were intentionally introduced. Our analysis shows that, D. rotundus on Anchieta Island were more likely to prey upon species from open habitats (mean value of −14.8‰), i.e., animals with high δ13C values characterized by the consumption of C4 resources. As expected for a top predator species, δ15N values for D. rotundus were higher (mean value of 8.2‰) and overlapped the niche of the capybaras (Hydrochoerus hydrochaeris) from the Anchieta Island, while it was distant from coatis, and also from those potential prey from the preserved area in the mainland, including the capybaras, indicating that among all potential mammalian prey species, they fed exclusively on capybaras, the highest mammalian biomass on island. Based on previous information on human occupation, the domestic animals present on Anchieta island might be the main prey of D. rotundus and responsible for maintaining a viable population. As the capybaras were introduced only 36 years ago, this suggests a rapid prey shift due to anthropogenic disturbances, which has allowed common vampire bats to successfully exploit them. Literature records also show that common vampire bats were not captured in preserved areas of the mainland which are near Anchieta Island indicating that the percentage of capture of D. rotundus is usually low in natural forested habitats where potential prey are scattered. As three individuals of introduced capybaras were confirmed died from bat rabies viruses (RABV) in 2020, we suggest periodic monitoring of bat rabies viruses in common vampire bat populations on Anchieta Island and areas nearby, in order to quantify the magnitude of the outbreak area and develop strategies for controlling, especially considering that the island and areas nearby is frequently visited by tourists. We highlighted that this prey choice is context-dependent, and possibly influenced by the removal of domestic animals, the explosive population growth of introduced capybaras combined with their predictable foraging behavior.

“…Dentre as espécies frugívoras registradas na área, as abundâncias de A. planirostris, P. lineatus, A. lituratus, S. lilium e C. perspicillata já eram esperadas, visto que essas espécies de morcegos são encontradas em grande abundância na Região Neotropical e com amplas distribuições geográficas (Reis et al 2007;Peracchi et al 2006;. Artibeus planirostris representa a espécie mais comum na região Nordeste do país (Garcia et al 2014) e no bioma Mata Atlântica (Muylaert et al 2017), já tendo sido mencionada por Barros et al (2017) como frequentemente capturada na área urbana da cidade de Natal (RN) e muito abundante em áreas naturais e antrópicas desse estado. Já A. lituratus é mais comum na região Sudeste e Centro-Oeste (Knegt et al 2005;Silva et al 2005).…”

In Brazil, only few works have been conducted regarding urban bats and information about richness, composition and ecological interactions in urban areas is little known. Additional studies are important to understand the dynamic of urban bats and offer strategies for their protection. In this paper, we present the results of a bat inventory at the Dois Irmãos campus of UFRPE, Recife, Pernambuco, northeastern Brazil, with analyzes of the composition, richness, diversity, and seasonal variation. From May 2006 to April 2007, we captured 950 bats from 16 species (five families). Frugivores bats accounted for 84.42% of the captures, followed by insectivores, piscivorous, nectarivores, omnivores, and hematophages. The species Artibeus planirostris was the most abundant. There was no significant difference (t = 0.35443, p = 0.7257) on abundance between the seasons of the year. We observed a richer and more diverse bat fauna as one would expect in an urban area, which suggests that the campus is being used for foraging, commuting, or as shelters for these animals.
