Reptiles, frequently traded as pets for their attractiveness, are particularly susceptible to such introductions, leading to shifts in distribution patterns and potential ecological impacts. The common chameleon (<em>Chamaeleo chamaeleon</em>), which has been historically introduced in several European countries, is such an example, yet no overall assessments are available to date for this species. In this study, we used ecological niche models to assess habitat suitability for the common chameleon in the Mediterranean basin for current and future scenarios. Concurrently, circuit theory techniques were employed to evaluate habitat connectivity in two historically introduced areas. We identified areas of high habitat suitability and dispersal corridors in introduced regions. Our results reveal a latitudinal gradient in habitat suitability changes, with the species facing both expansion and decline in different parts of its range, depending on the ecozone considered. Severe declines are noted in southeastern Spain, Tunisia, and Israel, while habitat suitability increases westwards in Portugal, Morocco, and Southern Italy. These insights contribute to a better understanding of the common chameleon’s ecological dynamics, providing a foundation for targeted management and conservation efforts. Our study highlights the importance of integrating ecological niche modelling and circuit theory techniques to predict habitat suitability and identify critical dispersal corridors for effective conservation strategies. Considering the ongoing challenges posed by human-mediated dispersals for the common chameleon, our research establishes a foundation for future studies to enhance our understanding of this elusive species.</p>","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140047213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also analyzed the importance of two factors for nest survival—water depth at nest site and egg concealment. Artificial nest survival was very low, with only about 8% of the nests surviving more than 10 days. Among the four most frequently recorded nest predators that comprised 95% of all predators filmed, the raccoon dog <i>Nyctereutes procyonoides</i> dominated (51.7% of records), followed by the marsh harrier <i>Circus aeruginosus</i> (24.5%), hooded crow <i>Corvus cornix</i> (12.2%), and American mink <i>Neogale vison</i> (11.6%).

The pathogenic significance of mycoplasmas varies widely between species. In birds where vocalization is crucial for reproductive success, mycoplasmas seem to be absent. Birds with high mycoplasma prevalence like birds of prey and storks do not rely on their vocalization for reproduction. Corvids with an intermediate prevalence use other strategies besides vocalization for mating. It is hypothesized that mycoplasma prevalence and vocalization used for reproduction is evolutionary related. Barn swallows have two traits relevant for mating: tail feather length and vocalization. An intermediate prevalence is expected. Little is known about mycoplasmas in barn swallows and their role as vector or reservoir for poultry pathogenic mycoplasmas. This study investigates the prevalence of mycoplasmas in barn swallows and their relevance for mycoplasma transmission to poultry. Choanal swabs from 188 healthy barn swallow nestlings of 59 different nests from ten different colonies on farms were examined for mycoplasmas by cultivation and genus-specific PCR including molecular biological differentiation of the species. In total, in 31 of 188 barn swallows (16.49%) and in 14 of the 59 nests (23.73%), mycoplasmas were detected.

The European wildcat has recently expanded its distribution in different parts of its range in Italy, including the Northern Apennines area. The current study represents the first wildcat systematic monitoring in the central part of Northern Apennines. Non-invasive genetic sampling—based both on valerian and catnip lures—was applied, integrated with camera trapping within two Regional Parks. This approach is needed in order to obtain hair samples to be genetically analyzed, since cross-breeding with domestic cats can make wildcat identification based only on coat characteristics misleading. Videos obtained from camera traps allowed the identification of several individuals (image capture rate of 1.04/100 trap-nights), including at least one female. Hair samples were only collected in April–May using catnip as an attractant, whereas the valerian-based solution used did not yield the expected results (i.e., attracting wildcats and stimulating their rubbing behavior to allow hair collection). These results allowed for the first time the genetic confirmation of a pure wildcat in the study area. Domestic cat presence (image capture rate of 1.4/100 trap-nights) was also assessed in the same locations, posing a possible threat for wildcat conservation at the expanding margin of its distribution.

Hunting is one of the well-known tools for population control; therefore, the aim of this study was to determine the effects of habitat type and weather conditions on jackal hunting success. From 2019 to 2023, a total of 217 jackals were culled during 106 hunting events in an approximately 10,500 ha lowland habitat along the Sava River in central Croatia. All jackals (56% males and 44% females) were culled using small calibre rifle (222 Remington) with night vision scope. Based on age structure, 16% juveniles and 84% adults were shot, and the average catch per unit effort (CPUE) was 2.0 animals/day. The best hunting success was obtained by attracting jackals with a calling method, i.e., by playing the sound of a wounded hare. Regarding the type of habitat, 56% of the culls were in cultivated, non-forested areas. It was confirmed that weather conditions, i.e., daily temperature and precipitation, influence hunting success, especially for males. Hunting success of adult males was lower on days with higher temperatures and on days with more precipitation.
