地理涵蓋範圍

The collection is primarily formed by specimens found in free-ranging domestic cat scats from two main regions of Spain, Montaña Palentina Natural Park (north of Palencia province) and the northeastern of the Sierra Nevada National and Natural Park, in the province of Almería. It also contains specimens from free-ranging cat owners throughout Spain who kindly sent us scats from their cats.

分類群涵蓋範圍

All specimens were identified to the most specific taxonomic level possible. Mandibles and teeth features were used to assess rodent species or genus. Scales from reptiles were usually used to reach order level. Feathers and calamus remains from birds did not allow us to get further from class level. Exoskeleton parts from arthropods, generally the third pair of legs, allowed us to identify some specimens to the species level, but most of them were identified to family level.

計畫資料

The project SUMHAL aims at implementing a strategy for biodiversity conservation in the western Mediterranean hotspot by setting a technologically efficient and scientifically robust system. The project combines fieldwork and virtual research environments for the recording, storing, analysis, and dissemination of the conservation status and threats of biodiversity in Andalusia (Southern Spain). The general aim of WP4 is to raise awareness of the ecological and socio-economic impacts of the three main human-induced drivers of global change: a) biological invasions; b) land-use changes; and c) food subsidies, that are of great global concern and therefore relevant not only to Andalusian and Spanish ecosystems and societies, but also to Europe as a whole. SUMHAL's WP4 aims to use traditional and other novel methodologies, mainly of remote animal monitoring, in addition to the participation of society to monitor ecological and socio-economic impacts at different spatial scales.

取樣方法

Scats were mainly collected from places near human settlements (towns, farms, isolated buildings...). For each sample, information associated with the cat that had deposited the excrement was associated when possible in form of two variables. Variable "Cat Type" describes the relationship of the cat with humans and includes the following categories: "Owned": cats that although left free outdoors (entirely or partially), are provided with at least regular food and shelter (veterinary care optional); "Colony cat": cats that live in groups in a specific area and spend their whole time outdoors basically because they do not belong to a specific owner. These may be often supported by caretakers or neighbours that provide them with food but do not consider themselves as owners. Variable "Care level" describes the frequency of food provided by people. It includes the following categories: "Fed": they have feeding guaranteed, either in form of controlled meals or "ad libitum"; "Semifed": they do not receive food in a regular manner or are fed insufficiently with cat food or leftovers and "Probably unfed": individuals found in such isolated or unpopulated places that they are unlikely to receive or have access to food coming from people. Therefore, they would only rely on their catches, although this category is difficult to prove.

方法步驟描述:

1. Sample processing: Scats were dried at 60 ºC degrees during 48-72h periods to avoid degradation by fungi or insects, as well as the transmission of possible diseases. Then, each sample was left in water for at least one day to hydrate and be able to separate the unidentifiable organic matter from undigested remains with a 500㎛ sieve. Remains such as fur, teeth, bones, mandibles, feathers, scales or hard parts of arthropod exoskeletons were kept in Petri plates for later identification. When content of scats consisted of more than 90% of dry cat food or leftovers, it was reported in "eventRemarks" field.
2. Morphological identification: All specimens were identified to the most specific taxonomic level possible. Mandibles and teeth features were used to assess rodent species or genera following the manual of Roman (2019). Scales from reptiles were usually used to reach order levels. Feathers and calamus remains from birds did not allow us to get further from the class level. Exoskeleton parts from arthropods were analysed by expert entomologists. Generally, the third pair of legs allowed us to identify some specimens at the species level, but most of them were identified at the family level. The variable "identificationMethod" within the dynamic properties in the Occurrence table details the body part found and used in each scat to reach the species identification level. Variables "individualCount" in Occurrence table refers to the minimum number of different individuals of the same species found in the scat. This estimation is done by counting body parts such as mandibles, teeth or legs that can only be present in a certain number in each individual (e.g. there were three upper left mandibles in the scat and one rodent can only have one, it means that at least three individuals were consumed). The variable "sampleSizeValue" in Event table represents the sum of all organisms consumed found in that scat (e.g. two mice and a grasshopper gives an individual count of three).
