Studies on bird behavior have benefited from the miniaturization of tracking devices and the opportunities for massive data collection facilitated by extensive satellite and cellular infrastructures. However, assessments of the effects of tracking devices on the behavior and survival of birds are rarely conducted and disseminated – raising animal ...

Leeches exhibit a marked scope of diversity, including different kinds of symbiosis. The aim of the present study was to demonstrate through biochemical and histological analysis that a species of piscicolid leech, Myzobdella platensis, is a true parasite of blue crabs, feeding on their hemolymph and using them as a site for cocoon deposition.

This study investigated the prevalence and diversity of Matryoshka RNA viruses (MaRNAV) in wild birds in the San Francisco Bay Area, California. Using RNA sequencing and RT‐PCR, we identified two novel MaRNAVs (MaRNAV‐5 and ‐6) associated with haemosporidian infections in passerines and raptors. These findings suggest a high prevalence of these viruses,

No Evidence for Male Retaliation in a Population With High Level of Extra‐Pair Paternity
In an experimental study, we investigated the relationship between within‐pair paternity of the males and their feeding rates in a monogamous passerine with a high rate of infidelity to reveal whether males recognise and penalise the unfaithfulness of their social partners. Our results contradict those previously found in another population of the same
