Broad snouted caiman (Caiman latirostris) growth under different rearing densities

open access: yesAquaculture, 2008
Abstract The effect of density on growth in body mass (BM) and total length (TL) of Caiman latirostris hatchlings raised in small pens (area 0.36 m2), for 3 months, was investigated. Twelve animals from each of three clutches were randomly distributed (1, 2 or 3 individuals) to two replicates at low rearing density (LRD: 0.12 m2/individual), medium ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

open access: yesThe Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Reduction of Ribonucleotide Reductase Subunit RRM2 Potentially Impairs Gut Function of Woody Breast Broilers

open access: yesAnimal Research and One Health, EarlyView.
Woody breast compromises meat quality leading to reduced consumer appeal. Although its causes are unclear, improvements observed with certain dietary supplements suggest that gut health may influence woody breast development. Ribonucleotide reductase subunit RRM2 is vital for mitochondrial function and gastrointestinal integrity, and alteration in its ...

Vocal patterns of adult females and juveniles Caiman yacare (Crocodilia: Alligatoridae) in Brazilian Pantanal wetland

open access: yesRevista de Biología Tropical, 2013
The Paraguayan caiman (Caiman yacare) is the main Caimaninae species occurring in the Brazilian Pantanal Wetland. Despite the relative availability of works focused on biology and conservation of the Paraguayan caiman, almost nothing is known about its ...

Combining monitoring data from multiple sites to assess population status and trends of White-tailed Tropicbirds (Phaethon lepturus) in the Seychelles

open access: yesAvian Conservation and Ecology, 2021
Seabirds, being long-lived top-level marine predators, are often considered to be valuable environmental indicators. With growing evidence of seabird declines worldwide, it is essential to monitor changes in populations and determine drivers of change ...

Levantamento de ninhos de jacarés em savanas inundáveis, Brasil. [PDF]

open access: yes, 2011
As planícies de inundação ocorrem no Brasil e em outras áreas na América do Sul. Algumas dessas são imensas, como é o caso do Pantanal, do "cerrado" no Estado de Rondônia e das Ilhas do Bananal, mas a maioria se espalha entre mosaicos ao longo de rios ...

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

open access: yesAnimal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...
