Egg perivitelline fluid of the invasive snail Pomacea canaliculata affects mice gastrointestinal function and morphology
Jörg Oehlmann –– The article contributes to the understanding of animal chemical defence mechanisms against predation and is also important from an evolutionary perspective as it describes a trait that could be a key factor for the broad geographical distribution for ampullariid snails.
Ultraconserved elements (UCEs) illuminate the population genomics of a recent, high-latitude avian speciation event
Michael Wink –– Use of UCE is a novel approach
A new species of Brachycephalus (Anura: Brachycephalidae) from southern Brazil
Jörg Oehlmann –– The identification and description of a new species in a highly threatened vertebrate taxonomic group is very important to conserve our biodiversity.
Function matters: a review of terminological differences in applied and basic clicker training research
Jennifer Vonk –– This will be a valuable resource for both researchers and trainers in more applied settings and will help to further the cause of empirical research to back accepted training regimes.
Functional significance of cuckoo Cuculus canorus calls: responses of conspecifics, hosts and non-hosts
Michael Wink –– interesting work on cuckoos
Nonspecific stress response to temperature increase in Gammarus lacustris Sars with respect to oxygen-limited thermal tolerance concept
Salvador Sánchez-Carrillo –– Biochemistry of environmental stress in organismal to be used as biomarkers
Th2 cytokine bias induced by silver nanoparticles in peripheral blood mononuclear cells of common bottlenose dolphins (Tursiops truncatus)
Susanne Brander –– It describes new findings regarding sublethal immunotoxic effects caused by a contaminant class (nanoparticles) of emerging concern in a marine organism of ecological importance.
Integrative taxonomy of the genus Pseudostegana (Diptera, Drosophilidae) from China, with descriptions of eleven new species
John Ringo –– Eleven new species are described. Classical morphological characters are analyzed alongside genetic data, a nice synthesis.
foxr1 is a novel maternal-effect gene in fish that is required for early embryonic success
Mason Posner –– This study uses the zebrafish to show that the foxr1 transcription factor is maternally inherited and important for early embryonic development. The authors use a combination of CRISPR genome editing and measurements of mRNA expression to provide compelling evidence for their conclusions. A phylogenetic analysis suggests that the importance of foxr1 may be widespread in vertebrates. This study is a good example of an integrative approach to examining vertebrate early development and an excellent use of the zebrafish model system.
Environmental stressors may cause equine herpesvirus reactivation in captive Grévy’s zebras (Equus grevyi)
Fernando Spilki –– The findings are of importance for those handling captive zebras.
