Carnivores, often identified as keystone species, can influence prey and subordinate carnivores through density- and behaviourally mediated pathways. Although the magnitude of their impacts remains debated, carnivores may trigger successional direct and indirect ecological effects on lower trophic levels in specific contexts, commonly known as trophic cascades. Felids, as ambush predators, have great potential to impact food webs. Yet, their influence on ecosystem dynamics remains understudied.
This global comprehensive literature review aimed to assess evidence for felids' ecological roles in trophic cascades across both natural and human-dominated ecosystems.
We found 61 publications that studied the influence of 18 felid species in trophic cascades. Research exhibited taxonomic and geographic biases, favouring big cats, temperate regions and biomes, as well as tropical moist forests in Central and South America. Of the studies, 23% (n = 14) were experimental, while 77% were observational or correlative. Among the latter, 60% tested at least one alternative hypothesis and 47% examined bottom-up processes.
Despite varying levels of inference, 80% of studies provide information consistent with trophic cascades involving felids. Their examination confirmed wild cats' ability to induce density- and behaviourally mediated trophic cascades, thereby influencing critical biotic and abiotic processes, including mesopredator control, functional diversity maintenance, and carbon storage. The magnitude of these effects may be altered in human-dominated landscapes, although current research effort remains too limited to draw conclusions.
In conclusion, felids may act as drivers of ecosystem change, and acknowledging their ecological roles can aid in promoting their conservation. However, we encourage more strongly inferential and comprehensive investigations into felid-mediated trophic cascades, prioritising research on small cats, felids in Asia and Africa, and the impacts of humans on trophic cascades, which can help to better inform conservation interventions and perspectives.

Dirofilaria species are mosquito-borne filarial nematodes, with a high veterinary and public health importance, but growing evidence also indicates their frequent occurrence in wildlife. Wild animals may play an important role in the maintenance, transmission and spread of dirofilariosis, but we have little understanding of the ecological and environmental processes that drive infection dynamics in these hosts. Here, we summarise the current knowledge about the distribution of Dirofilaria spp. across carnivore host species and geographic localities in the Palearctic region. This summary highlights that some of these sylvatic species may be important reservoirs of the pathogen, and identifies research trends and biases in the surveillance and monitoring of this host–parasite system in the wild. Furthermore, we provide directions for future research for a better understanding of the threat these parasites may pose to wild mammals.
