Fitting fangs in a finite face: A novel fang accommodation strategy in a 280-million-year-old ray-finned fish. [PDF]
J Anat, 2023 Left jaws of †Brazilichthys macrognathus (DGM 1061‐P) in mesial view. Palatoquadrate sectioned to expose the fenestration of the maxilla and the fangs of the lower jaw (in red). Scale bar = 10 mm. Abstract Though Paleozoic ray‐finned fishes are considered to be morphologically conservative, we report a novel mode of fang accommodation (i.e., the ...

A bristle-nosed Jurassic ray-finned fish (Actinopterygii) bears true dermal odontodes on its snout. [PDF]
J AnatTeeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

River connectivity increases the diversity of fish communities in gravel pit lakes
Transactions of the American Fisheries Society, Volume 152, Issue 5, Page 550-576, September 2023., 2023 Abstract Objective Off‐channel floodplain features are important components of a river system that provide habitat and boost regional species pools, but river–floodplain connectivity is disrupted by anthropogenic activities. The Campbell Lakes in Harrison, Ohio, are formerly isolated gravel pits along the Whitewater River and are connected to the river

Fish and Fisheries, Volume 24, Issue 5, Page 829-847, September 2023., 2023 Abstract Remote sensing technology offers the ability to derive information on freshwater fish habitats across broad geographic areas and has the potential to transform approaches to monitoring. However, the numerous platforms, sensors and analytical software that are available may overwhelm those interested in utilizing this important technology and ...

Journal of Fish Biology, Volume 103, Issue 3, Page 472-480, September 2023., 2023 Abstract Colder water temperatures are generally regarded as a stressful period for fishes (i.e., winter stress syndrome), which can be exacerbated by cold‐shock stress associated with major arctic freezes. Although cold‐shock stress and mass mortalities are well documented for coastal marine fishes, few studies report the effects of winter stress or ...
