By altering or eliminating delicate ecological relationships, non-indigenous species are considered a major threat to biodiversity, as well driver of environmental change. Global climate change affects ecosystems and communities, leading changes in the phenology, geographic ranges, population abundance several species. Thus, predicting impacts global on current future distribution invasive is an important subject macroecological studies. The African clawed frog (Xenopus laevis), native South...
The frequent introduction and rapid spread of invasive alien species (IAS) along with the limited resources available for their management highlight need to adopt simple effective methods prioritizing efforts. Here, we propose a technically model actions, using Sicily (southern Italy) as case study. Despite its invasion being relatively recent not yet widespread, highly red swamp crayfish Procambarus clarkii proved be able colonize different habitat types on this Mediterranean island. We...
Abstract The worldwide spread of invasive species is considered to be one the main causes global amphibian declines and loss biodiversity in general. African Clawed Frog, Xenopus laevis, shows a strong ability establish populations invade various geographic regions. In 2004 X. laevis was found Sicily for first time. Sicilian population probably largest Europe with range about 225 km2 an area characterized by numerous agricultural ponds. This high density ponds has potentially facilitated...
Abstract Although of crucial importance for invasion biology and impact assessments climate change, it remains widely unknown how species cope with adapt to environmental conditions beyond their currently realized climatic niches (i.e., those existing populations are exposed to). The African clawed frog Xenopus laevis , native southern Africa, has established numerous invasive on multiple continents making a pertinent model organism study niche dynamics. In this study, we assess whether the...
African clawed frogs of the widespread polytypic species Xenopus laevis Daudin, 1802 (ranging large parts sub-Saharan Africa) have been spreading since 1940s, and established reproductive populations in Europe, Asia Americas, where they can negative impact as competitors native amphibians disease vectors for chytridomycosis or ranaviruses. Here we use two mitochondrial (cytochrome b, 16S rDNA) one nuclear (RAG 1: Recombination Associated Gene 1) DNA markers to infer potential origin invasive...
Bufo viridis Laurenti, 1768 is a common species that inhabits wide variety of habitats. The different climates characterising its broad range lead to high degree variability in seasonal activity and reproductive cycle. This paper reports some observations carried out on the breeding phenology this over two year period Mediterranean temporary ponds Sicily. Sicilian green toads extends into autumn months, making it longer than other Italian populations. behaviour seems due impact xeric...

graphical regions, and 15% in the Continental one. However, there were no statistical significant differences among suggesting that rate of amphibian site loss was similar different parts Italy. This nation-wide monitoring project demonstrated Italy, during last thirty years, a relevant proportion breeding habitats has been destroyed or altered. The main cause alteration land reclamation water extraction.
The conservation status of amphibians is often assessed using public databases because a lack up-to-date field data. However, it crucial that this kind data used carefully, evaluating the reliability and consistency information. In Italy, painted frog, Discoglossus pictus , was recently databases, outcome highlighted worrying situation for species. We analyzed these conclusions reassessed taking into account its insular distribution new species occurrence. Our results contrast with previous...
European rabbit is, among mammals, one of the most widespread species almost worldwide, introduced on over 800 islands. In microinsular habitats, introduction alien represents a major threat to biodiversity, and is included in IUCN published list 100 worst invasive species. 2008, an eradication plan was launched “Isola delle Femmine”, small uninhabited island about 14.5 ha, located Mediterranean basin established as nature reserve 1997 protect its flora vegetation. The present work conducted...
