“…E incluso se han detectado híbridos del gato doméstico y el gato de la selva o gato rojo (Felis chaus) en Egipto (Li et al, 2016). En el caso del perro doméstico, por su interacción y cercanía filogenética con otras especies de cánidos puede llegar a hibridarse, habiendo reportes de híbridos de perro doméstico con lobos (Anderson et al, 2009;Pilot et al, 2021;Popova y Zlatanova, 2020;VonHoldt et al, 2013), lobos etíopes (Gottelli et al, 1994(Gottelli et al, , 2013Leonard et al, 2014), coyotes (Canis latrans; Leonard et al, 2014;Weeks et al, 1990) y chacales dorados (Canis aureus; Galov et al, 2015;Leonard 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.

“…In fact, anthropogenic hybridization between wolves and dogs has often been a topic of scientific debate owing to its potential conservation implications (e.g. Donfrancesco et al., 2019; Hindrikson et al., 2017; Salvatori et al., 2020; Stronen et al., 2022), which include the dilution of genetic distinctiveness of wolves through dog introgression, and disruption of behaviour and local adaptations (Bassi et al., 2017; Caniglia et al., 2014; Popova & Zlatanova, 2019; Salvatori et al., 2019). The occurrence of wolf–dog hybridization correlates with disruption of social structure in wolf packs and it is more frequent in peripheral areas of the wolf range, particularly in fragmented and small populations (Galaverni et al., 2017; Godinho et al., 2011; Hindrikson et al., 2017), which are outnumbered by free‐ranging dogs (Pilot et al., 2021; Randi & Lucchini, 2002).…”

After decades of intense persecution, the Iberian wolf subspecies faced a severe bottleneck in the 1970s that considerably reduced its range and population size, nearly leading to its extinction in central and southern Iberian Peninsula. Such population decline could have impacted the genetic diversity of Iberian wolves through different processes, namely genetic drift and dynamics of hybridization with domestic dogs. By contrasting the genomes of 68 contemporary with 54 historical samples spanning the periods before and immediately after the 1970s bottleneck, we found evidence of its impact on genetic diversity and dynamics of wolf–dog hybridization. Our genome‐wide assessment revealed that wolves and dogs form two well‐differentiated genetic groups in Iberia and that hybridization rates did not increase during the bottleneck. However, an increased number of hybrid individuals was found over time during the population re‐expansion, particularly at the edge of the wolf range. We estimated a low percentage of dog ancestry (~1.4%) in historical samples, suggesting that dog introgression was not a key driver for wolf extinction in central and southern Iberia. Our findings also unveil a significant decline in genetic diversity in contemporary samples, with the highest proportion of homozygous segments in the genome being recently inherited. Overall, our study provides unprecedented insight into the impact of a sharp decline on the Iberian wolf genome and refines our understanding of the ecological and evolutionary drivers of wolf–dog hybridization in the wild.

“…These negative consequences are particularly pronounced in small, fragmented and isolated populations [ 51 ]. Moreover, introgressive hybridization can also affect feral populations of domesticated animals [ 52 , 53 ]. Cross-breeding between individuals originating from captive-bred populations and their wild conspecifics may have similar consequences as that between domesticated and wild populations [ 54 ].…”

Hybridization, defined as breeding between two distinct taxonomic units, can have an important effect on the evolutionary patterns in cross-breeding taxa. Although interspecific hybridization has frequently been considered as a maladaptive process, which threatens species genetic integrity and survival via genetic swamping and outbreeding depression, in some cases hybridization can introduce novel adaptive variation and increase fitness. Most studies to date focused on documenting hybridization events and analyzing their causes, while relatively little is known about the consequences of hybridization and its impact on the parental species. To address this knowledge gap, we conducted a systematic review of studies on hybridization in mammals published in 2010–2021, and identified 115 relevant studies. Of 13 categories of hybridization consequences described in these studies, the most common negative consequence (21% of studies) was genetic swamping and the most common positive consequence (8%) was the gain of novel adaptive variation. The total frequency of negative consequences (49%) was higher than positive (13%) and neutral (38%) consequences. These frequencies are biased by the detection possibilities of microsatellite loci, the most common genetic markers used in the papers assessed. As negative outcomes are typically easier to demonstrate than positive ones (e.g., extinction vs hybrid speciation), they may be over-represented in publications. Transition towards genomic studies involving both neutral and adaptive variation will provide a better insight into the real impacts of hybridization.
