Structure and fracture resistance of alligator gar (Atractosteus spatula) armored fish scales.
The alligator gar is a large fish with flexible armor consisting of ganoid scales. These scales contain a thin layer of ganoine (microhardness ~2.5 GPa) and a bony body (microhardness ~400 MPa), with jagged edges that provide effective protection against predators. We describe here the structure of both ganoine and bony foundation and characterize the mechanical properties and fracture mechanis...
متن کاملFine Structure of the Gas Bladder of Alligator Gar, Atractosteus spatula
Anthropogenic factors seriously affect water quality and adversely affect fish populations. Agricultural run-off accumulates in the Mississippi River and the coastal estuaries. Alligator gar (Atractosteus spatula) inhabits these waters and is impacted by agricultural pollution, petrochemical contaminants and oil spills. These fish are bimodal air breathers, and use a primitive lung as an access...
متن کاملCloning of the growth hormone cDNA of alligator gar Atractosteus spatula and its expression through larval development.
The alligator gar (Atractosteus spatula) is the largest freshwater fish inhabiting rivers draining into the Gulf of Mexico. This primitive fish shows a fast growth rate since its early larval stages. This is attributed to the action of growth hormone (GH), an anterior pituitary gland hormone responsible for linear growth in vertebrates that can also be expressed in extrapituitary adult tissues ...
متن کاملAcute toxicity and cholinesterase inhibition of the nematicide ethoprophos in larvae of gar Atractosteus tropicus (Semionotiformes: Lepisosteidae).
Biomarkers are a widely applied approach in environmental studies. Analyses of cholinesterase (ChE), glutathione S-transferase (GST) and lipid peroxidation (LPO) are biomarkers that can provide information regarding early effects of pollutants at different biochemical levels on an organism. The aim of this study was to evaluate the biomarker approach on a Costa Rican native and relevant species...
متن کاملCystoopsis atractostei n. sp. (Nematoda: Cystoopsidae) from the subcutaneous tissue of the tropical gar, Atractosteus tropicus (Pisces), in Mexico.
A new species of parasitic nematode, Cystoopsis atractostei (Trichinelloidea: Cystoopsidae), is described based on female specimens recovered from the subcutaneous tissue of the tropical gar, Atractosteus tropicus Gill (Lepisosteiformes: Lepisosteidae), from 2 localities (Canal Nueva Esperanza and Canal Tabasquillo) of the Pantanos de Centla Biological Reserve, State of Tabasco, southeastern Me...
