“…Otras respuestas adaptativas de las pulgas incluyen el relativo tamaño pequeño, el cuerpo estrecho y comprimido bilateralmente con una cabeza denominada cuneiforme, la flexibilidad articulada de los segmentos torácicos, la movilidad de las patas delanteras, también las patas traseras elongadas y aparatos sensoriales para la detección del movimiento de los hospederos. Con todas estas adaptaciones, pueden moverse activamente sobre el hospedero y entre las diminutas partículas de la superficie del suelo y realizar saltos para desplazarse en poco tiempo a distancias mayores a lo largo y ancho del cuerpo del hospedero (Medvedev, 2017).…”

Las pulgas son insectos ectoparásitos hematófagos, es decir, viven externamente y se alimentan de la sangre de animales vertebrados como mamíferos y aves, los cuales fungen como sus hospederos. Han evolucionado con sus hospederos a través de una asociación ecológica llamada parasitismo, en la cual la selección natural ha influido en ambos grupos a través del mecanismo evolutivo conocido como la carrera armamentista, la cual propone que para sobrevivir los individuos de dos especies o más han evolucionado constantemente durante el proceso competitivo de desarrollo de estrategias o características morfológicas, fisiológicas o conductuales, para evitar la extinción. Por lo tanto, la carrera armamentista en el parasitismo ha jugado un papel importante en la diversificación de pulgas y hospederos.

“…Second, we asked whether the relative roles of turnover components for rare and common interactions differed between networks situated in different continents. Differences between host–flea networks from different continents can be expected because of different histories of host–flea relationships (Medvedev, 1996, 2005). Third, we asked whether environmental drivers of interaction turnover were similar or different between (a) turnover components, (b) rare and common interactions, and (c) continental networks.…”

“…Although fleas have been thought to originate in Gondwana (Zhu et al, 2015), their diversification outburst likely happened in the Palearctic (Medvedev, 1996(Medvedev, , 2005, resulting in the Palearctic having the highest flea species richness (about 900) as compared to other biogeographic realms (Krasnov, 2008). This high diversity could stem from 2 not mutually exclusive processes, namely in situ diversification (Morrone and Gutiérrez, 2005) and dispersal from other realms (Krasnov and Shenbrot, 2002;Gibert et al, 2021).…”

Combining the biogeography and phylogenetic patterns of parasite-host associations allows a better understanding of the history of parasite–host interactions, which can be achieved via biogeographic regionalization incorporating phylogenetic information. Recently, the concepts of evoregions (regions where a majority of species evolved from one or several ancestors inhabiting these regions) and evolutionary transition zones (regions of high phylogenetic turnover) have been proposed, coupled with a classification approach for these concepts. We applied this approach to 206 flea species and 265 host species of the Palearctic and aimed to identify evoregions and evolutionary transition zones for both fleas and hosts and to understand whether these evoregions and transition zones match each other. We identified 5 evoregions with 3 transition zones for either fleas or hosts, but neither the positions and boundaries of the flea and host evoregions nor the transition zones coincided. Indications of multiple geographic centres of diversification of the same flea lineages suggested that (a) the common evolutionary history of fleas and hosts was characterized by multiple events other than codiversification and that (b) dispersal played an important role in flea and host assemblies. Barriers to dispersal could be represented by landscape features (deserts and mountain ranges) and/or climate differences.
