Evidence of recombination in putative ancient asexuals.
Gandolfi A, Sanders IR, Rossi V, Menozzi P. Gandolfi A, et al. Mol Biol Evol. 2003 May;20(5):754-61. doi: 10.1093/molbev/msg081. Epub 2003 Apr 2. Mol Biol Evol. 2003. PMID: 12679528
Ancient asexuals have been considered to be a contradiction of the basic tenets of evolutionary theory. Barred from rearranging genetic variation by recombination, their reduced number of gene arrangements is thought to hamper their response to changing environments. ...Se …

Phylogenetic relationships of coexisting Heterocypris (Crustacea, Ostracoda) lineages with different reproductive modes from Lampedusa Island (Italy).
Rossi V, Gandolfi A, Baraldi F, Bellavere C, Menozzi P. Rossi V, et al. Mol Phylogenet Evol. 2007 Sep;44(3):1273-83. doi: 10.1016/j.ympev.2007.04.013. Epub 2007 May 3. Mol Phylogenet Evol. 2007. PMID: 17553707
Different reproductive modes were associated with a peculiar morphological trait: a lamella hyalina on the posterior margin of the left valve was observed in amphimictic females, a feature missing in apomictic females. ...We identified three main evolutionary …

Mother's Age and Hatching Phenology Strategy of Heterocypris incongruens (Crustacea: Ostracoda) in Unpredictable Environment.
Rossi V, Gandolfi A, Menozzi P. Rossi V, et al. J Exp Zool A Ecol Genet Physiol. 2016 Dec;325(10):701-712. doi: 10.1002/jez.2062. Epub 2017 Feb 7. J Exp Zool A Ecol Genet Physiol. 2016. PMID: 28168840
Clonal females showed a diversified bet-hedging strategy to spread risk of reproduction in ponds with unpredictable hydroperiod. ...Genetically identical eggs kept at the same controlled laboratory conditions showed a U-shaped distribution of development time. ...

Persistence of asexuality through mixed reproduction in Eucypris virens (Crustacea, Ostracoda).
Schön I, Gandolfi A, Di Masso E, Rossi V, Griffiths HI, Martens K, Butlin RK. Schön I, et al. Heredity (Edinb). 2000 Feb;84 ( Pt 2):161-9. doi: 10.1046/j.1365-2540.2000.00647.x. Heredity (Edinb). 2000. PMID: 10762385
However, we argue that such data can only provide a lower limit on the number of origins of asexual reproduction, and an upper limit on the age of asexual lineages. ...

The evolutionary jigsaw puzzle of the surviving trout (Salmo trutta L. complex) diversity in the Italian region. A multilocus Bayesian approach.
Gratton P, Allegrucci G, Sbordoni V, Gandolfi A. Gratton P, et al. Mol Phylogenet Evol. 2014 Oct;79:292-304. doi: 10.1016/j.ympev.2014.06.022. Epub 2014 Jul 3. Mol Phylogenet Evol. 2014. PMID: 24997330
Mediterranean trout populations display a diversity of phenotypes, representing a valuable model for the study of adaptation and a puzzling dilemma for taxonomists and biogeographers, which is further entangled by the widespread introgression of allochthonous …

Frequent recombination shapes the epidemic population structure of Planktothrix (Cyanoprokaryota) in Italian subalpine lakes.
D'Alelio D, Salmaso N, Gandolfi A. D'Alelio D, et al. J Phycol. 2013 Dec;49(6):1107-17. doi: 10.1111/jpy.12116. Epub 2013 Oct 1. J Phycol. 2013. PMID: 27007631
Association indices among alleles at different loci were suggestive of an "epidemic population structure," resulting from an explosive (and temporary) dominance of one genotype against a panmictic background. ClonalFrame analyses supported this view by detecting: (i) three …

New Evidences of Mitochondrial DNA Heteroplasmy by Putative Paternal Leakage between the Rock Partridge (Alectoris graeca) and the Chukar Partridge (Alectoris chukar).
Gandolfi A, Crestanello B, Fagotti A, Simoncelli F, Chiesa S, Girardi M, Giovagnoli E, Marangoni C, Di Rosa I, Lucentini L. Gandolfi A, et al. PLoS One. 2017 Jan 23;12(1):e0170507. doi: 10.1371/journal.pone.0170507. eCollection 2017. PLoS One. 2017. PMID: 28114306 Free PMC article.
We analyzed a Cytochrome oxidase I (COI) fragment of contemporary and historical A. graeca and A. chukar samples, using duplicated analyses to confirm results and nuclear DNA microsatellites to exclude possible sample cross-contamination. In two contemporary …

Defining conservation units in a stocking-induced genetic melting pot: unraveling native and multiple exotic genetic imprints of recent and historical secondary contact in Adriatic grayling.
Meraner A, Cornetti L, Gandolfi A. Meraner A, et al. Ecol Evol. 2014 Apr;4(8):1313-27. doi: 10.1002/ece3.931. Epub 2014 Mar 18. Ecol Evol. 2014. PMID: 24834328 Free PMC article.
Within the Adige River system, a contact zone of western Adriatic and eastern Danubian populations was detected, with ABC analyses suggesting a historical anthropogenic origin of eastern Adige populations, most likely founded by medieval translocations. ...We finall …

Massive invasion of exotic Barbus barbus and introgressive hybridization with endemic Barbus plebejus in Northern Italy: where, how and why?
Meraner A, Venturi A, Ficetola GF, Rossi S, Candiotto A, Gandolfi A. Meraner A, et al. Mol Ecol. 2013 Nov;22(21):5295-312. doi: 10.1111/mec.12470. Epub 2013 Sep 18. Mol Ecol. 2013. PMID: 24103005
However, the magnitude of the problem across a native species range, the mechanisms shaping introgression as well as invader's dispersal and the relative role of biological invasions in the light of multiple environmental stressors are rarely described. ...Therefore, immed …
