Abstract Stable isotope analysis (SIA) is widely used to reconstruct food webs, characterize trophic relationships, and estimate dietary composition. However, bulk tissue SIA (BSIA) can yield imprecise estimates when dietary sources are isotopically similar.

Coincident Tick Infestations in the Nostrils of Wild Chimpanzees and a Human in Uganda [PDF]
Ticks in the nostrils of humans visiting equatorial African forests have been reported sporadically for decades, but their taxonomy and natural history have remained obscure. We report human infestation with a nostril tick in Kibale National Park, Uganda,

Overview of Arachnids and Arachnology in Iran [PDF]
An overview of the Arachnida and their study in Iran is provided. Besides ancient poetry, relics (going back to 5,000 YBP), and early medical observations (at least 2,000 YBP), the first published taxonomical observations of arachnids from Iran were in ...

Argas vespertilionis (Ixodida: Argasidae): A parasite of Pipistrel bat in Western Iran
Ticks (suborder Ixodida) ecologically divided into two nidicolous and non-nidicolous groups. More argasid ticks are classified into the former group whereas they are able to coordinate with the specific host(s) and living inside/adjacent to their host’s ...

ABSTRACT Hybridization and introgression frequently occur even between distantly related species. A central question in speciation research is which genomic regions act as barriers to gene flow and how genome‐wide differentiation persists despite hybridization between species.

Ticks and tick‐borne pathogens (TBPs) threaten livestock productivity and public health worldwide, and climate–land‐use change is expanding vector habitats, elevating tick‐borne disease risk. However, TBP diversity and risk in Hubei Province, central China, remain insufficiently defined within a One Health framework.

Automated identification of spotted‐fever tick vectors using convolutional neural networks
We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.
