Urban ecosystems are a patchwork of habitats that host a broad diversity of animal species. Insects comprise a large portion of urban biodiversity which includes many pest species, including those that transmit pathogens. Mosquitoes (Diptera: Culicidae) inhabit urban environments and rely on sympatric vertebrate species to complete their life cycles, and in this process transmit pathogens to animals and humans. Given that mosquitoes feed upon vertebrates, they can also act as efficient samplers that facilitate detection of vertebrate species that utilize urban ecosystems. In this study, we analyzed DNA extracted from mosquito blood meals collected temporally in multiple neighborhoods of the San Juan Metropolitan Area, Puerto Rico to evaluate the presence of vertebrate fauna. DNA was collected from 604 individual mosquitoes that represented two common urban species, Culex quinquefasciatus (n = 586) and Aedes aegypti (n = 18). Culex quinquefasciatus fed on 17 avian taxa (81.2% of blood meals), seven mammalian taxa (17.9%), and one reptilian taxon (0.85%). Domestic chickens dominated these blood meals both temporally and spatially, and no statistically significant shift from birds to mammals was detected. Aedes aegypti blood meals were from a less diverse group, with two avian taxa (11.1%) and three mammalian taxa (88.9%) identified. The blood meals we identified provided a snapshot of the vertebrate community in the San Juan Metropolitan Area and have potential implications for vector-borne pathogen transmission.

ABSTRACTThe Functional Compensation Hypothesis (Hochberg 1986a, b) interprets frequent expression of pronominal subjects as compensation for frequent deletion of agreement marking on finite verbs in Puerto Rican Spanish (PRS). Specifically, this applies to 2sg.túwhere variably deleted word-final -smarks agreement. If the hypothesis is correct, finite verbs with agreement deleted in speech should co-occur more frequently with pronominal subjects than finite verbs with agreement intact. Likewise, social dialects which frequently delete agreement should show higher rates of pronominal expression than social dialects which less frequently delete agreement. These auxiliary hypotheses are tested across a socially stratified sample of 62 speakers from San Juan. Functional compensation does show stylistic and social patterning in the category of Specifictú, not in that of Non-specifictú. However, Non-specifictúis the key to frequency differences between -s-deleting PRS and -s-conserving Madrid; hence the Functional Compensation Hypothesis should be discarded.
