This study investigated the performance and microbiome of cyclic denitrification filters (CDFs) for wood sulfur heterotrophic-autotrophic (WSHAD) saline wastewater. Wood-sulfur CDFs integrated into two pilot-scale marine recirculating aquaculture systems achieved high rates (103 ± 8.5 g N/(m3·d)). The combined use pine resulted in lower SO42? accumulation compared with prior wastewater studies ...

Twenty-four adult molly fish (Poecilia sphenops, Valenciennes 1846) were collected to study the morphology and distribution of ganglia using histological, immunohistochemical, electron microscopy focusing on their relation immune cells. The classified spatially into cranial spinal, functionally sensory autonomic. Spinal (dorsal root ganglia, DRG) contained large close ganglionic cells, enclosed...

Accurately delimiting species is fundamentally important for understanding species diversity and distributions and devising effective strategies to conserve biodiversity. However, species delimitation is problematic in many taxa, including 'non-adaptive radiations' containing morphologically cryptic lineages. Fortunately, coalescent-based species delimitation methods hold promise for objectivel...
