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 ...

The complete mitochondrial DNA of the Cuban gar (Atractosteus tristoechus) [PDF]

Mitochondrial DNA. Part B. Resources, 2017
The Cuban gar (Atractosteus tristoechus) is an endemic lepisosteid living in Cuba. Among gars, this species is one of the most threatened and has the smallest natural distribution range. Lepisosteids are air-breathing fishes belonging to the Holostean, a

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

Advances in remote sensing of freshwater fish habitat: A systematic review to identify current approaches, strengths and challenges

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 ...

Long‐term patterns in inland fish kills associated with cold‐shock and winter stress: a regional case study from Texas

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 ...

Assessment of listing and categorisation of animal diseases within the framework of the Animal Health Law (Regulation (EU) No 2016/429): infectious pancreatic necrosis (IPN)

EFSA Journal, Volume 21, Issue 6, June 2023., 2023
Abstract Infectious pancreatic necrosis (IPN) was assessed according to the criteria of the Animal Health Law (AHL), in particular, the criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9, and Article 8 for ...

Overlooked Invaders? Ecological Impacts of Non‐Game, Native Transplant Fishes in the United States

Fisheries, Volume 48, Issue 2, Page 62-71, February 2023., 2023
Nonnative fishes can cause ecological impacts as invasive species, but identifying which nonnative species have harmful impacts is critical to prioritizing management and policy responses. Here, we characterized the state of knowledge on the impacts of a possibly overlooked group of invasive species in the United States: non‐game native transplant ...
