Size-assortative mating in a long-lived monogamous seabird
Visalli, Francesca; De Pascalis, Federico; Morinay, Jennifer; Campioni, Letizia; Imperio, Simona; Catoni, Carlo; Maggini, Ivan; Benvenuti, AndreaMate choice is a key process in animals to optimize the ftness benefts of reproduction, and it is generally guided by phenotypic features of potential partners that mirror reproductive abilities. Assortative mating occurs when there is within-pair selection for specifc functional traits that can confer ftness benefts. Assortative mating can be positive if mates are more similar, and negative if they are more di...
How genomics can help biodiversity conservation
Theissinger, Kathrin; Fernandes, Carlos; Formenti, Giulio; Bista, Iliana; Berg, Paul R.; Bleidorn, Christoph; Bombarely, Aureliano; Crottini, AngelicaABSTRACT: The availability of public genomic resources can greatly assist biodiversity assessment, conservation, and restoration efforts by providing evidence for scientifically informed management decisions. Here we survey the main approaches and applications in biodiversity and conservation genomics, considering practical factors, such as cost, time, prerequisite skills, and current shortcomings of applicatio...
Year-round variation in the isotopic niche of Scopoli's shearwater (Calonectris...
Campioni, Letizia; Dell'Omo, Giacomo; Vizzini, Salvatrice; De Pascalis, Federico; Badalamenti, Fabio; Massa, Bruno; RUBOLINI, DIEGO; Cecere, Jacopo G.Top marine predators are key components of marine food webs. Among them, long-distance migratory seabirds, which travel across different marine ecosystems over the year, may experience important year-round changes in terms of oceanographic conditions and availability of trophic resources. We tested whether this was the case in the Scopoli’s shearwater (Calonectris diomedea), a trans-equatorial migrant and top p...
