The effects of global glaciations on the distribution organisms is an essential element many diversification models. However, empirical evidence supporting this idea mixed, in particular with respect to explaining tropical forest evolution. In present study, we evaluated impacts range shifts associated Pleistocene glacial cycles evolution forests. particular, tested predictions: (1) that population genetic structure increases fragmentation variation between and Last Glacial Maximum (LGM)...
In seabirds, the extent of population genetic and phylogeographic structure varies extensively among species. Genetic is lacking in some species, but present others despite absence obvious physical barriers (landmarks), suggesting that other mechanisms restrict gene flow. It has been proposed seabirds best explained by relative overlap non-breeding distributions birds from different populations. We used results analysis microsatellite DNA variation geolocation (tracking) data to test this...
Avian trichomonosis is known as a widespread disease in columbids and passerines, recent findings have highlighted the pathogenic character of some lineages found wild birds. Trichomonosis can affect bird populations including endangered species, has been shown for Mauritian pink pigeons Nesoenas mayeri Mauritius suggested European turtle doves Streptopelia turtur UK. However, caused only by parasite Trichomonas gallinae. Therefore, understanding prevalence distribution both potentially...
Understanding how past climatic oscillations have affected organismic evolution will help predict the impact that current climate change has on living organisms. The European turtle dove, Streptopelia turtur, is a warm-temperature adapted species and long distance migrant uses multiple flyways to move between Europe Africa. Despite being abundant, it categorized as vulnerable because of long-term demographic decline. We studied history population genetic structure dove using genomic data...
'Nebbiolo' is a grapevine cultivar typical of north-western Italy, appreciated for producing high-quality red wines. Grapevine cultivars are characterized by possessing highly heterozygous genomes, including great incidence genomic rearrangements larger than 50 bp, so called structural variations (SVs). Even though abundant, SVs an under-explored source genetic variation mainly due to methodological limitations at their detection.We employed multiple platform approach produce long-range data...
Abstract To preserve their varietal attributes, established grapevine cultivars (Vitis vinifera L. ssp. vinifera) must be clonally propagated, due to highly heterozygous genomes. Malbec is a France-originated cultivar appreciated for producing high-quality wines and the offspring of Prunelard Magdeleine Noire des Charentes. Here, we have built diploid genome assembly Malbec, after trio binning PacBio long reads into two haploid complements inherited from either parent. After haplotype-aware...
Abstract Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio‐temporal scales. They also conserved among closely related species, making them potentially useful clarifying interspecific relationships between recently diverged taxa. However, mutations primer binding sites may lead increased nonamplification, or disruptions that result in decreased polymorphism nontarget species. Furthermore, high mutation rates and constraints on allele size with...
Parasites can exert selection pressure on their hosts through effects survival, reproductive success, sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability. Consequently, hemoparasites have become the focus of recent avian studies. Infection varies significantly among taxa. Various factors might explain differences infection taxa, including habitat, climate, host density, presence vectors, life history immune defence....
Abstract We studied the phenotypic variation of Atlantic Forest passerine Xiphorhynchus fuscus (Aves: Dendrocolaptidae) with broad aim addressing whether history and type forest affected evolution endemic taxa. also tested different subspecies genetic lineages X. could be considered full species. collected plumage body size measurements and, in combination data, used multivariate tests to evaluate working hypotheses. Our results, combined previous biogeographic analyses, indicate that...
Speciation through homoploid hybridization (HHS) is considered extremely rare in animals. This mainly because the establishment of reproductive isolation as a product uncommon. Additionally, many traits are underpinned by polygeny and/or incomplete dominance, where hybrid phenotype an additive blend parental characteristics. Phenotypically intermediate hybrids usually at fitness disadvantage compared with species and tend to vanish backcrossing population(s). It therefore unknown whether...
Abstract Grapevine cultivars are clonally propagated to preserve their varietal attributes. However, genetic variations accumulate due the occurrence of somatic mutations. This process is anthropically influenced through plant transportation, clonal propagation and selection. Malbec a cultivar that well-appreciated for elaboration red wine. It originated in Southwestern France was introduced Argentina during 1850s. In order study diversity grapevines, we generated whole-genome resequencing...
Hypogeococcus pungens, a mealybug native of southern South America, is devastating cacti in Puerto Rico and threatening cactus diversity the Caribbean, potentially Central North America. The taxonomic status H. pungens controversial since it has been reported feeding not only on Cactaceae but also other plant families throughout its distribution range. However, Australia, where species had exported from Argentina to control weedy American cacti, was never found host plants than Cactaceae....
Abstract Aim Understanding how natural populations respond to climatic shifts is a fundamental goal of biological research in fast‐changing world. The Southern Ocean represents fascinating system for assessing large‐scale climate‐driven change, as it contains extremely isolated island groups within predominantly westerly, circumpolar wind and current system. Blue‐eyed shags represent paradoxical seabird radiation—a distribution implies strong dispersal capacity yet their species‐rich nature...
Abstract Interspecific introgression can occur between species that evolve rapidly within an adaptive radiation. Pachyptila petrels differ in bill size and are characterised by incomplete reproductive isolation, leading to interspecific gene flow. Salvin’s prion ( salvini ), whose width is intermediate broad-billed P. vittata ) Antarctic desolata prions, evolved through homoploid hybrid speciation. MacGillivray’s macgillivrayi known from a single population on St Paul (Indian Ocean), has...
Malbec is Argentina's flagship variety, and it internationally recognized for producing high-quality red wines. Fruit set rate a major component in grapevine yield determination, the outcome of multiple genetic environmental interacting variables. Here, we characterized reproductive performance 25 clones grown under homogeneous conditions 23-years old experimental plot. We measured traits near flowering (like number flowers per inflorescence) at harvest (including berries cluster berry...
The accession Criolla Chica Nº2 (CCN2) is catalogued as a floral mutation of cultivar (synonym for cv. Listán Prieto). Contrary to what observed in hermaphrodite-cultivated varieties like Chica, CCN2 exhibits prevalence masculinized flowers. Aiming study the incidence and phenotypical implications this mutation, plants were deeply studied using 'Ballista' (CCBA) control plants. For each plant, two inflorescences per shoot sampled segmented into proximal, mid distal positions, relative...
A wide spectrum of song complexity has been documented in a broad range animal taxa. However, the underlying processes shaping acoustic differences are still poorly understood. Empirical and theoretical studies suggest that different parameters may be subject to tempos modes evolution, resulting complex combination stabilizing directional selection change among populations through time. Nonetheless, contribution genetic drift divergence is largely unexplored. In this study, we used QST–FST...
Abstract Grapevine cultivars ( Vitis vinifera L. ssp. ) must be clonally propagated because of their highly heterozygous genomes. Malbec, a France-originated cultivar appreciated for the production high-quality wines, is offspring Prunelard and Magdeleine Noire des Charentes. Here, we have built diploid genome assembly after trio binning PacBio long reads into two haploid complements inherited from either parent. After haplotype-aware deduplication corrections, complete assemblies...
