ABSTRACT FLEAS, HOSTS AND HABITAT: WHAT CAN WE PREDICT ABOUT THE SPREAD OF VECTOR-BORNE ZOONOTIC DISEASES? MEGAN M. FRIGGENS Vector-borne diseases of humans and wildlife are experiencing resurgence across the globe. I examine the dynamics of flea borne diseases through a comparative analysis of flea literature and analyses of field data collected from three sites in New Mexico: The Sevilleta National Wildlife Refuge, the Sandia Mountains and the Valles Caldera National Preserve (VCNP). My objectives were to use these analyses to better predict and manage for the spread of diseases such as plague (Yersinia pestis). To assess the impact of anthropogenic disturbance on flea communities, I compiled and analyzed data from 63 published empirical studies. Anthropogenic disturbance is associated with conditions conducive to increased transmission of flea-borne diseases. Most measures of flea infestation increased with increasing disturbance or peaked at intermediate levels of disturbance. Future trends of habitat and climate change will probably favor the spread of flea-borne disease.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Fleas (Siphonaptera) are Cretaceous, and Evolved with Theria Qiyun Zhu1, Michael Hastriter2, Michael Whiting2, 3, Katharina Dittmar1, 4* Jan. 23, 2015 Abstract: Fleas (order Siphonaptera) are highly-specialized, diverse blood-feeding ectoparasites of mammals and birds with an enigmatic evolutionary history and obscure origin. We here present a molecular phylogenetic study based on a compre- hensive taxon sampling of 259 flea taxa, representing 16 of the 18 extant families of this order. A Bayesian phylogenetic tree with strong nodal support was recovered, consisting of seven sequentially derived lineages with Macropsyllidae at the base and Stephanocircidae as the second basal group. Divergence times of flea lineages were estimated based on fossil records and host specific associations to bats (Chiroptera), showing that the common ancestor of extant Siphonaptera split from its clos- est mecopteran sister group in the Early Cretaceous and basal lineages diversified during the Late Cretaceous. However, most of the intraordinal divergence into families took place after the K-Pg boundary. Ancestral states of host association and bioge- ographical distribution were reconstructed, suggesting with high likelihood that fleas originated in the southern continents (Gondwana) and migrated from South America to their extant distributions in a relatively short time frame. Theria (placental mammals and marsupials) represent the most likely ancestral host group of extant Siphonaptera, with marsupials occupying a more important role than previously assumed.

Bv. 120 s/n e/ Av. 60 y calle 61, 1900 La Plata, Argentina. [email protected] Abstract. A high diversity of fleas parasitizing sigmodontine rodents has been mentioned for Patagonia. Several of these fleas have been described having their type localities in the region, including several endemic taxa. For many species, however, the original descriptions are brief and there are no new morphological contributions. In the present study we report 8 species of fleas (Ctenophthalmidae, Rhopalopsyllidae and Stephanocircidae) parasitizing sigmodontine rodents from Argentinean Patagonia. Nineteen new parasite–host associations are reported and all studied fleas extend their known geographic range. Among them, Tiarapsylla argentina is mentioned for the first time for Patagonia; Craneopsylla minerva, Sphinctopsylla ares, Polygenis (P.) platensis and Polygenis (P.) rimatus are registered for the first time for Chubut, and Agastopsylla boxi, Ectinorus (E.) ixanus and Ectinorus (E.) hapalus for Santa Cruz, extending the southernmost limit of their geographical distribution.
