is a novel symbiont of marine invertebrates that exhibits broad patterns of phylosymbiosis.

Despite growing insights into the composition of marine invertebrate microbiomes, our understanding of their ecological and evolutionary patterns remains poor, owing to limited sampling depth and low-resolution datasets. Previous studies have provided mixed results when evaluating patterns of phylosymbiosis between marine invertebrates and marine bacteria. Here, we investigated potential animal-microbe symbioses in , an overlooked bacterial genus consistently identified as a core microbiome taxon in diverse invertebrates.

Mitochondrial 16S rDNA sequences help identify North American ticks in the genus Argas (Acari: Argasidae).

Argas (Acari: Argasidae) ticks in the United States include 8 species that parasitize domestic fowl and numerous wild avian species. Ticks infesting a single nest tree of a bald eagle Haliaeetus leucocephalus (Linnaeus) in southern Arizona (United States) were received for identification and included 2 species, Argas (Persicargas) radiatus Railliet (Acari: Argasidae) and Argas (Persicargas) ricei Hoogstraal, Kaiser, Clifford & Keirans (Acari: Argasidae). Their identities were based on key morphological characters supported by mitochondrial 16S rDNA sequences compared to museum reference specimens.

GENOMICS AND MORPHOLOGY RESOLVE CHIPMUNK SUCKING LOUSE SYSTEMATICS (GENUS HOPLOPLEURA).

Sucking lice are obligate parasites of eutherian mammals and are generally considered to be host-specific parasites. Molecular investigations have found that some current louse taxonomy is incorrect and does not reflect the relationships among families and species. Western chipmunks (23 species of Tamias) and the eastern chipmunk (Tamias striatus) are infested by 2 different species of Hoplopleura sucking lice, Hoplopleura arboricola and Hoplopleura erratica.

DETECTION OF RICKETTSIA AND BARTONELLA IN FLEAS AND TICKS COLLECTED FROM PETS AT VETERINARY CLINICS IN GEORGIA, UNITED STATES.

Many human infections are transmitted through contact with household pets. The purpose of this cross-sectional study was to determine the occurrence of ticks and fleas on pets (dogs and cats) in local veterinary clinics in Statesboro, Georgia. We screened ectoparasites for Rickettsia and Bartonella and assessed owner knowledge and practices related to tick- and flea-borne diseases.

James Edward Keirans (1935-2023): A Bibliography, Described Taxa and Eponyms/Patronyms.

A bibliography is provided of the 228 scientific publications authored by James E. Keirans, a prominent American tick taxonomist and medical entomologist, together with chronologically organized lists of the tick taxa that he described and the eponyms and patronyms named in his honor.
