Abstract Invasive arthropod vectors and the range expansions of native vectors can lead to public and veterinary health concerns, as these vectors may introduce novel pathogens or spread endemic pathogens to new locations. Recent tick invasions and range expansion in the United States has been attributed to climate and land use change, an increase in global travel, and importations of exotic animals. A 10 year surveillance study was conducted on Block Island, Rhode Island from 2010–2020 including sampling ticks from small mammal and avian hosts. We report the discovery and establishment of the red sheep tick for the first time in the western hemisphere and in the United States. This invasive species was first collected in 2010 on Block Island, was collected continuously throughout the study, and was collected from an avian host. We document the first report of the invasive Asian longhorned tick in the state of Rhode Island, first observed at our sites in 2018. Finally, we present data on the range expansion and establishment of two native tick species, the lone star tick and the rabbit tick on Block Island. This study emphasized the importance of long-term surveillance to detect changes in tick host communities, including invasive and expanding native vectors of potential significance to humans and wildlife.

The Brewer's blackbird (Euphagus cyanocephalus) is rapidly expanding its range eastward across Ontario and parts of the United States. This study was to determine if phenetic changes have taken place during or immediately after expansion. A sample was collected in 1968 in the vicinity of McKerrow, Ontario, near the periphery of the zone of expansion and where breeding was first recorded in 1962. For comparison, a second collection was made in the stable part of the range near Winnipeg, Manitoba. Statistical comparisons for 37 skin and skeletal characters were made between the two samples for both sexes. Tests for differences in character means suggest that strong directional selection, different from that in the stable part of the range, is not operating in the newly occupied area. Likewise, differences in population variability seem slight and do not show alterations in genetic variability that would be expected during a Carsonian population flush or that would be expected because of a partial founder effect.

The Mediterranean Gecko, Hemidactylus turcicus, is known to have colonized nearly every state in the southern United States. In Louisiana, the Mediterranean Gecko has been documented in many of the southern parishes, but records for the northern portion of the state are limited. We sampled northern Louisiana parishes to document the presence of the Mediterranean Gecko. We sampled a total of 21 parishes in northern Louisiana and found geckos in 17 of those parishes, 16 of which represent new distribution records for the species. This indicates a significant range expansion of this introduced species throughout northern Louisiana. Geckos were found across a temperature range of 14.0–28.0°C and had a strong association with buildings. The species’ affinity for anthropogenic association and the continual nature of anthropogenic expansion facilitate the high vagility of this species. The result is a successful colonization throughout much of Louisiana and likely continued range expansion throughout the southern United States.
