“…We calculated the proportion of diet contributed by each prey species with regard to both frequency of kills and edible biomass (Table ). We assessed dietary diversity by calculating a prey diversity index using the Shannon–Wiener diversity index (Yip et al ) for each housing density level at the 150‐m and 1‐km scales. We also calculated prey diversity for males and females and used Mann–Whitney U non‐parametric tests to examine sex differences in housing metrics (i.e., proximity, density, clustering) and proportion of small prey consumed.…”

Understanding how anthropogenic development affects food webs is essential to implementing sustainable growth measures, yet little is known about how the spatial configuration of residential development affects the foraging behavior and prey habits of top predators. We examined the influence of the spatial characteristics of residential development on prey composition in the puma (Puma concolor). We located the prey remains of kills from 32 pumas fitted with global positioning system (GPS) satellite collars to determine the housing characteristics most influencing prey size and species composition. We examined how differences in housing density, proximity, and clustering influenced puma prey size and diversity. We found that at both local (150 m) and regional (1 km) spatial scales surrounding puma kill sites, housing density (but not the clustering of housing) was the greatest contributor to puma consumption of small prey (<20 kg), which primarily comprised human commensals or pets. The species-specific relationships between housing density and prey occupancy and detection rates assessed using camera traps were not always similar to those between housing density and proportions of diet, suggesting that pumas may exercise some diet selectivity. The influence of development on puma diet may affect puma disease risk, energetics, and demographics because of altered species interactions and prey-specific profiles of energetic gain and cost. Our results can help guide future land-use planners seeking to minimize the impacts of development on wild species interactions and community dynamics. Ó 2016 The Wildlife Society.

“…Adicionalmente, los gatos son la principal amenaza potencial para 8% de las especies de aves, mamíferos y reptiles en peligro de extinción (Medina et al, 2011). Específicamente para el caso de aves insulares, después de los roedores exóticos, los gatos son los segundos depredadores en importancia, atribuyéndoles casi 26% de las extinciones de especies dentro de este grupo (Bonnaud et al, 2011;Doherty et al, 2016;Loss et al, 2013;Yip et al, 2014).…”

Los gatos y perros domésticos son las mascotas preferidas del hombre, por lo que se han convertido en especies invasoras y los carnívoros más abundantes del planeta. A pesar de su buena relación con nuestra especie, tienen un impacto ecológico negativo con consecuencias para las políticas de conservación. Los efectos que estos animales tienen sobre la fauna silvestre han sido estudiados principalmente en países con baja biodiversidad de vertebrados (EUA, Nueva Zelanda y Europa), y salvo por algunos trabajos realizados en Australia, Brasil, y México, no contamos con información sobre sus efectos en países con alta biodiversidad. Los efectos negativos que ambas especies tienen sobre la biodiversidad incluyen la depredación y competencia con fauna nativa, su hibridación con especies filogenéticamente cercanas o poblaciones silvestres de su propia especie, y la transmisión de enfermedades a la fauna silvestre y a los humanos. La falta de información sobre los efectos de depredadores introducidos a nivel continental y la falsa idea de que los gatos y perros son ambientalmente inocuos, vuelve crucial aumentar la investigación sobre estas especies en países megadiversos para proponer estrategias de manejo que fomenten la conservación de fauna nativa.

Nine ways to score nine lives – identifying appropriate methods to age domestic cats (Felis catus)

et al. 2021

Accurate determination of chronological age for cats (Felis catus) permits assessment of age at reproduction and growth measures, whilst understanding survivorship enables modelling of population dynamics underpinning many management questions. At present, the relative accuracy of different measures has not been compared, especially in relation to ageing live cats, where options are more limited. We tested relationships between nine ageing methods using a large database of 384 unowned, free‐roaming cats culled as part of wildlife conservation and unowned cat management. Cat heads were cleaned and scored for tooth eruption, development of the canines (root closure, length and width; proportion of pulp determined by radiography), canine tooth cementum lines, tooth wear (canine tip sharpness and breakage, or absence of the P2), diastema distance and closure of two cranial sutures. Tooth eruption is informative for cats up to about 8 months of age and closure of the canine root up to 12 months. In adults with closed‐rooted canine teeth, only the cementum lines and cranial sutures varied; these two sets of measures were strongly correlated. We conclude by developing a predictive table for ageing cat specimens using tooth and skull features. Animals can be aged reliably over the lifespan of the animal from cadaver material, potentially adding valuable information to ecological studies where cats are culled. However, there is no way to reliably age live cats over approximately 8 months of age in the field, after which time full adult dentition is established. Similarly, radiography (to determine pulp volume) has limited use as an ageing tool for cats older than 1–2 years of age. This reduces the number of potential applications for live cats, including, for example, ageing unowned cats in trap–neuter–release programmes.
