Structure and dynamics of an invasive population of the red swamp crayfish (Procambarus clarkii) in a Mediterranean wetland
TLDR
The structure and dynamics of the study population seem to reveal its stability and spreading potential, as a confirmation of the invasiveness of P. clarkii in Mediterranean wetlands. Expand
The first record of the marbled crayfish adds further threats to fresh waters in Italy
TLDR
Molecular analyses based on COI barcoding did not reveal any differentiation within the P. clarkii population and excluded any form of hybridization between the two species, and will shortly discuss new pathways of invasive species and the threats posed by parthenogenetic species, even though they seem to be still sporadic. Expand
Population structure and dynamics of Procambarus clarkii (Girard, 1852) in a Mediterranean brackish wetland (Central Italy)
TLDR
The present study showed that this species has a lower growth rate and higher longevity than other studied European P. clarkii populations, and that it can damage brackish habitats and human livelihoods, for the conservation of Mediterranean coastal habitats. Expand
The new threat to Italian inland waters from the alien crayfish “gang”: the Australian Cherax destructor Clark, 1936
TLDR
Based on morphological and genetic evidence, an established population of an alien species of crayfish, new for Italy, was found in the Natural Preserve of “Laghi di Ninfa” (central Italy) and classified at subspecies level as the Parastacidae Cherax destructor destructor, native to Australia. Expand
Disjunct distribution of the Mediterranean freshwater crab Potamon fluviatile—natural expansion or human introduction?
TLDR
It is argued that the freshwater crab Potamon fluviatile, which has a disjunct distribution on the Balkan Peninsula, Italy, Sicily and Malta, should be included in the national conservation management in Italy. Expand
Revisiting reproduction and population structure and dynamics of Procambarus clarkii eight years after its introduction into Lake Trasimeno (Central Italy)
TLDR
Investigating reproductive and growth plasticity in the invasive crayfish Procambarus clarkii in Lake Trasimeno indicates some changes in population dynamics and in both molting and reproductive periods since the initial invasion of the shallow lake investigated. Expand
Fine-scale genetic structure, phylogeny and systematics of threatened crayfish species complex.
TLDR
This study hypothesized an evolutive scenario in which the separation of ancient mtDNA lineages likely occurred before the latest glacial periods, and proposed that the taxonomic hypothesis of a single species of A. pallipes, settling the Italian continental waters, is affected by complex evolutionary events. Expand
Occurrence of allochthonous freshwater crayfishes in Latium (Central Italy)
TLDR
The present study confirmed their ecological plasticity, strong capability of invasion and adaptation to new environments of all three species, due to their rapid growth, utilisation of different trophic resources and the frequency and length of their reproduction periods. Expand
Understanding population structure and dynamics in threatened crayfish
TLDR
Analysis of nearly 8000 crayfish collected from May to October of the years 2001–2004 showed a well-structured population and a low growth rate, the latter showing evident seasonality in both sexes, and sexual differences were found. Expand
Shape and size variations in the cranium of elephant-shrews: a morphometric contribution to a phylogenetic debate
TLDR
The results are congruent with data obtained from previous biochemical research and support the traditional subdivision in two subfamilies, the monophily of the genus Elephantulus and its closeness with Petrodromus, relating to their similar cranium shapes. Expand
