Wildcat scats: Taphonomy of the predator and its micromamal prey
2019
Small sized felids, such as wild and domestic cats, are one of the most common predators in the nature and in sites occupied by humans in archaeological and historical contexts. Wildcats have ingestion/ digestion traits highly destructive for their prey, i.e.: teeth to chew causing extreme breakage, and digestion along the entire digestive tract with low pH gastric juices causing extreme bone corrosion. Small sized cats are also well known to play with the prey and select skeletal parts to ingest. The present study is focused on the taphonomic analysis of micromammal remains recovered from scats produced by European wildcats (Felis silvestris silvestris) during several months and years. Exc…
The value of by-catch data: how species-specific surveys can serve non-target species
2019
Camera trapping has a wide range of research application, but, while research designs are often focused on the study of a single focal species, cameras can also record other non-target species. Occupancy modeling using by-catch data can be a valuable resource to gain information on these species maximizing the scientific effort and efficiency of wildlife surveys. In this study, we used by-catch data from a European wildcat (Felis silvestris silvestris) survey in Southern Italy to assess the habitat covariates determinant for the occupancy of the crested porcupine (Hystrix cristata). We recorded 33 detections at 17 out of 51 cameras (naive occupancy = 0.33). The best models fitted the data w…
Habitat fragmentation and anthropogenic factors affect wildcat Felis silvestris silvestris occupancy and detectability on Mt Etna
2019
International audience; Knowledge of patterns of occupancy is crucial for planning sound biological management and for identifying areas which require paramount conservation attention. The European wildcat Felis silvestris is an elusive carnivore and is classified as ‘least concern' on the IUCN red list, but with a decreasing population trend in some areas. Sicily hosts a peculiar wildcat population, which deserves conservation and management actions, due to its isolation from the mainland. Patterns of occupancy for wildcats are unknown in Italy, and especially in Sicily. We aimed to identify which ecological drivers determined wildcat occurrence on Mt Etna and to provide conservation actio…
Record of a 10-year old European Wildcat Felis silvestris silvestris Schreber, 1777 (Mammalia: Carnivora: Felidae) from Mt. Etna, Sicily, Italy
2020
Longevity data for wild felids are lacking in the literature. Here we report a camera trap recapture of a European Wildcat Felis silvestris at Mt. Etna in Sicily, Italy after nine years. This individual was clearly identifiable as its tail ended with a white ring rather than the typical black ring and had a unique shape of the dorsal stripe. At first capture on 26 May 2009, this cat was assessed as an adult, so that the likely minimum age of this individual at the time of recapture on 10 June 2018 must have been be at least 10 years. This finding represents the oldest known European Wildcat in the wild and provides insight into age structure in wildcat populations.
Genetic structure of wildcat (Felis silvestris) populations in Italy
2013
Severe climatic changes during the Pleistocene shaped the distributions of temperate-adapted species. These species survived glaciations in classical southern refuges with more temperate climates, as well as in western and eastern peripheral Alpine temperate areas. We hypothesized that the European wildcat (Felis silvestris silvestris) populations currently distributed in Italy differentiated in, and expanded from two distinct glacial refuges, located in the southern Apennines and at the periphery of the eastern Alps. This hypothesis was tested by genotyping 235 presumed European wildcats using a panel of 35 domestic cat-derived microsatellites. To provide support and controls for the analy…
Update of the distribution and habitat use of the wildcat, pine marten and weasel in Sicily
2020
The wildcat (Felis silvestris), the pine marten (Martes martes) and the weasel (Mustela nivalis) are key members of the mammalian community in Sicily, actually performing the role of top predators and consequently influencing the trophic chain both in natural and agricultural areas. However, despite their protected status, very little information is available regarding their occurrence and ecology. Here, by verifying published studies, collecting personal observations and analyzing novel field data obtained by camera traps, we update their spatial distribution in Sicily, contributing to a better understanding of their habitat use and suggesting future research to improve our knowledge of th…
The European wildcats (Felis silvestris silvestris) as reservoir hosts of Troglostrongylus brevior (Strongylida: Crenosomatidae) lungworms.
2014
The increasing reports of Troglostrongylus brevior lungworm in domestic cats from Italy and Spain raised questions on its factual distribution and on the role wildcats play as reservoirs of these parasites. Carcasses of 21 wildcats were collected in natural parks of southern Italy (i.e., Catania, Sicily n = 5 and Matera, Basilicata n = 16) and biometrically and genetically identified as Felis silvestris silvestris, but two as hybrids. Troglostrongylus brevior and Eucoleus aerophilus lungworms were found in 15 (71.4%) and 7 (33.3%) individuals, respectively, being five (23.8%) co-infected by the two species. Both lungworms showed an aggregated distribution in the host population, assessed by…
Show me your tail, if you have one! Is inbreeding depression occurring in wildcats (Felis silvestris silvestris) from Italy?
2022
Knowledge of genetic diversity is important to wildlife conservation because genetically depleted populations experience an increased risk of extinction. Mammalian carnivores are characterized by small and fragmented populations and low dispersal, so that genetic erosion can lead to the fixation of deleterious genes relatively quickly, leading to morphological abnormalities. Kinked tails and cowlicks are indicative of inbreeding depression and have been described in two wild cat species so far, the puma (Puma concolor) and the cheetah (Acinonyx jubatus). Here we report the first records of morphological abnormalities in five populations of the European wildcat (Felis silvestris silvestris) …
