Regression equations between body and head measurements in the broad-snouted caiman (Caiman latirostris) [PDF]

Revista Brasileira de Biologia, 2000
In the present study, regression equations between body and head length measurements for the broad-snouted caiman (Caiman latirostris) are presented. Age and sex are discussed as sources of variation for allometric models. Four body-length, fourteen head-length, and ten ratio variables were taken from wild and captive animals.

Effects of Low Concentration of Glyphosate‐Based Herbicide on Genotoxic, Oxidative, Inflammatory, and Behavioral Meters in Danio rerio (Teleostei and Cyprinidae)

Biochemistry Research International, Volume 2024, Issue 1, 2024.
The glyphosate herbicide is a pesticide widely used in the world and can contaminate soil, air, and water. The objective of this work was to evaluate the toxicity of a glyphosate‐based herbicide (GBH) in zebrafish (Danio rerio). Fish were exposed to different concentrations of GBH (0, 50, 250, and 500 µg/L) for 96 hours.

Cranial sexual discrimination in hatchling broad-snouted caiman (Caiman latirostris) Discriminación de sexo en neonatos de yacaré overo (Caiman latirostris)

Iheringia: Série Zoologia, 2007
Broad-snouted caiman (Caiman latirostris) hatchlings present a consistent sexual dimorphism in their cranium shape and size. Male hatchlings have smaller crania than females. Using multivariate statistical analyses it is possible to discriminate sex in broad-snouted caiman hatchlings by their cranial shape with a reasonable efficiency.
