Negative impacts of dominance on bee communities: Does the influence of invasive honey bees differ from native bees?Lucas Alejandro Garibaldi, Lucas Garibaldi, Néstor Pérez-Méndez, Guaraci Cordeiro, Alice Hughes, Michael Orr, Isabel Alves Dos Santos, Breno Freitas, Favízia Freitas De Oliveira, Gretchen Lebuhn, Ignasi Bartomeus, Marcelo Aizen, Patricia Andrade, Betina Blochtein, Danilo Boscolo, Patricia Drumond, Maria Gaglianone, Barbara Gemmill-Herren, Rosana Halinski, Cristiane Krug, Marcia Maues, Lucia Piedade Kiill, Mardiore Pinheiro, Carmen Pires & Blandina Felipe Viana
Invasive species can reach high abundances and dominate native environments. One of the most impressive examples of ecological invasions is the spread of the African sub-species of the honey bee throughout the Americas, starting from its introduction in a single locality in Brazil. The invasive honey bee is expected to more negatively impact bee community abundance and diversity than native dominant species, but this has not been tested previously. We developed a comprehensive and systematic...
Fruit abundance and trait matching determine diet type and body condition across frugivorous bird populationsJuan P. González-Varo, Alejandro Onrubia, Néstor Pérez-Méndez, Rubén Tarifa & Juan C. Illera
Research on seed-dispersal mutualisms has been highly unbalanced towards the plants, largely overlooking the fitness effects of fruit resources on frugivorous animals. Moreover, despite morphological mismatches like gape limitation may reduce the abundance of fruits that are actually accessible to a frugivore species, there is very little evidence on the trait-matching implications from a frugivore’s perspective. Here, we refine recent resource-provisioning models to comprehensively test the joint effects of fruit abundance and trait matching on...
Determining the mechanisms of community assembly forms the foundation of biogeography and community ecology. Studies of the biodiversity and distribution of Neotropical macro-organisms have revealed the roles of environmental, spatial, and historical factors in structuring communities at different spatial and temporal scales, but the role of these factors play for species and communities on microorganisms are still poorly known. Diatoms are a very species-rich group of algae, disperse widely, and sensitive to environmental variation due...
Hazelnut SSR database: genetic profiles of the accessions, list of synonyms, and true-to-type genotypesPaolo Boccacci, Maria Aramini, Matthew Ordidge, Theo Van Hintum, Daniela Torello Marinoni, Nadia Valentini, Jean-Paul Sarraquigne, Anita Solar, Mercè Rovira, Loretta Bacchetta & Roberto Botta
Hazelnut (Corylus avellana L.) is one of the most important tree nut crops in Europe. Germplasm accessions are conserved in ex situ repositories, located in countries where hazelnut production occurs. In this work, we used ten simple sequence repeat (SSR) markers as the basis to establish a core collection representative of the hazelnut genetic diversity conserved in different European collections. A total of 480 accessions were used: 430 from ex situ collections and 50 landraces...
The world is rapidly urbanizing, thereby transforming natural landscapes and changing the abundance and distribution of organisms. However, insights into the effects of urbanization on species interactions, and plant-pathogen interactions in particular, are lacking. We investigated the effects of urbanization on powdery mildew infection on Quercus robur at continental and within-city scales. At the continental scale, we compared infection levels between urban and rural areas of different-sized cities in Europe, and investigated whether plant traits,...
