Genomic selection signatures in farmed Colossoma macropomum from tropical and subtropical regions in South AmericaVito Mastrochirico Filho
Tambaqui or cachama (Colossoma macropomum) is one of the most important neotropical freshwater fish used for aquaculture in South America, and its production is concentrated at low latitudes (close to the Equator, 0°), where the water temperature is warm. Therefore, understanding how selection shapes genetic variations and structure in farmed populations is of paramount importance in evolutionary biology. High-throughput sequencing to generate genome-wide data for fish species allows for elucidating the genomic basis of adaptation...
Forest cover and connectivity have pervasive effects on the maintenance of evolutionary distinct interactions in seed dispersal networksErison Carlos Dos Monteiro, Marco Pizo, Maurício Humberto Vancine & MIlton Ribeiro
Seed dispersal by animals is one of the most important ecological processes in tropical forests, entailing millions of years of evolutionary adaptations of plants and frugivorous animals forming networks of interactions that, ultimately, contribute to the resilience of such forests. We analyze 29 seed dispersal networks in the threatened Atlantic Forest biodiversity hotspot, with data on the frequency of feeding visits by birds to fruiting plants to answer: (1) which are the effects of forest...
Abundance predominates over niche factors as determinant of the frequency of interactions between frugivorous birds and plantsMarco Aurelio Pizo, Tomas Carlo, Aarón González-Castro & Antonio Fontanella
Neutral and niche factors influence the structure of frugivory and seed dispersal networks. While the former refers to the abundance of interacting species, niche factors refer to traits that mediate interactions between species (e.g., morphology). The challenge is to unravel in which circumstances one kind of factor predominates over the other, or how much variation is explained by each factor. We investigated the relative contributions of abundance and trait-matching (considering fruit’s size, pulp mass to...
Dataset for: Short flowers for long tongues: functional specialization in a nocturnal pollination network of an asclepiad in long-tongued hawkmoths (Biotropica)Felipe W. Amorim, Salvador Marino, Priscila Andre Sanz-Veiga, Jeff Ollerton & Paulo E. Oliveira
Since Darwin, very long and narrow floral tubes have been known to represent the main floral morphological feature for specialized long-tongued hawkmoth pollination. However, specialization may be driven by other contrivances instead of floral tube morphology. Asclepiads are plants with a complex floral morphology where primary hawkmoth pollination had never been described. We detailed here the intricate pollination mechanism of the South American asclepiad Schubertia grandiflora, where functional specialization on long-tongued hawkmoth pollinators occurs despite...
Mixed-species flocking is associated with low arthropod detectability and increased foraging efficiency by Yungas forest birds in ArgentinaG. Giselle Mangini, Karl Mokross, Facundo Gandoy & Juan Ignacio Areta
Mixed-species flocks presumably provide birds with antipredator and foraging benefits. The foraging benefits hypothesis predicts that a reduction in arthropod abundance will trigger flocking activity; however, flocking activity may also be influenced by the difficulty of detecting arthropods, a seldom explored possibility. We found that environmental traits (temperature and foliage density) combined with arthropod abundance explained arthropod detection by birds in the Yungas foothill forest of NW Argentina. Prey detection was inversely related to ambient...
Response of seed germination to smoke water solutions in Cerrado plant species collected between 2013 and 2020H.L. Zirondi, R.M. Kolb, A.R. Martins, A. Fidelis, T. Steinbrecher, M. Pérez, G. Leubner-Metzger, J.O. Chandler, G.S.T. Motta & R.G. Martins
This dataset contains information about how seeds collected from Brazilian Cerrado plant species germinate in smoke water and control water solutions. Seeds were collected from site across the Cerrado between 2013 and 2020. Germination was assessed in laboratory experiments by placing seeds on wet filter paper with water and smoke water solutions. Two different methods were used. One used a commercially available smokewater, Regen 2000 and the other used smoke water produced from burning biomass...
Present and future distribution of bat hosts of sarbecoviruses: implications for conservation and public healthRenata Lara Muylaert, Tigga Kingston, Jinhong Luo, Maurício Humberto Vancine, Nikolas Galli, Colin Carlson, Reju Sam John, Maria Cristina Rulli & David Hayman
Global changes in response to human encroachment into natural habitats and carbon emissions are driving the biodiversity extinction crisis and increasing disease emergence risk. Host distributions are one critical component to identify areas at risk of viral spillover, and bats act as reservoirs of diverse viruses. We developed a reproducible ecological niche modelling pipeline for bat hosts of SARS-like viruses (subgenus Sarbecovirus), given that several closely-related viruses have been discovered and sarbecovirus-host interactions have gained...
