Abstract:
... Taxonomic status of the noctuid moth Mesapamea remmi Rezbanyai‐Reser (Lepidoptera) has remained controversial since its description in 1985. Based on morphology, it has been considered a valid species or a hybrid between Mesapamea secalis (Linnaeus) and Mesapamea didyma (Esper). We studied this case of uncertain identity by using traditional Sanger sequencing techniques (COI and seven nuclear gene ...

Abstract:
... Grouper is an important food fish due to its commercial value. A major production constraint in culturing grouper is that the fish can be fatally affected by leeches and diseases. Leeches are an ectoparasite of grouper, which can cause significant loss in fish number, and thus controlling their prevalence is indispensable as a tool of aquaculture management. In order to understand the prevalence a ...

Christ applied the name Aspidium × arendsii to this hybrid. In the following decades the ...
