Early evolution of the gular musculature and its innervation in ray‐finned fishes
The Anatomical Record, EarlyView.Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Integrative Zoology, EarlyView.We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Comparing lacustrine environments: the importance of the kind of habitat on the structure of fishes
Acta Limnologica Brasiliensia, 2018 Aim Fish diversity in two lentic environments: a lake connected (Barbosa lake) to a river and an artificial reservoir (Ninfeias reservoir) were determined in the dry and rainy periods in 2015. We expected to find more diversity in the connected lake and
