T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Effects of 5,6-dimethylbenzimidazole and cobalt supplementation in high-concentrate diets on rumen fermentation and microorganisms and ruminal metabolome in sheep

BMC Veterinary Research
Background Regular use of high-concentrate diets can improve the growth of animals, especially high-yielding cattle and sheep. However, high-concentrate diets can alter rumen fermentation and microbial community structure, leading to rumen acidosis ...

A phosphoprotein gene RT-qPCR assay for detecting all lineages of peste des petits ruminants virus

Frontiers in Microbiology
Peste des petits ruminants (PPR) is a highly contagious disease caused by peste des petits ruminants virus (PPRV). PPRV is classified into four lineages based on the nucleocapsid (N) or fusion (F) genes.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Effects of forest fragmentation and tree diversity on herbivore abundance and number of herbivore species. [PDF]

, 2014
Light to dark grey shaded areas depict low to high values for (left panel) herbivore abundance and (right panel) number of herbivore species per tree species per study site based on model fit; small to large radii of circles depict low to high values of ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Larval parasitism of the autumnal moth reduces feeding intensity on the mountain birch [PDF]

, 2013
Plants respond to grazing by herbivorous insects by emitting a range of volatile organic compounds, which attract parasitoids to their insect hosts. However, a positive outcome for the host plant is a necessary precondition for making the attraction ...

​Indole is an essential herbivore-induced volatile priming signal in maize [PDF]

, 2015
Herbivore-induced volatile organic compounds prime non-attacked plant tissues to respond more strongly to subsequent attacks. However, the key volatiles that trigger this primed state remain largely unidentified.

Quercetin ameliorates aflatoxin B1-induced non-canonical ferroptosis in ovine oocytes through the OPA1/ACSL4 pathway

Journal of Animal Science and Biotechnology
Background Aflatoxin B1 (AFB1), a potent mycotoxin, commonly contaminates feeds like maize and soybean, jeopardizing animal reproduction. Although AFB1 exposure is known to cause oxidative stress, immune activation, and cell death in oocytes and early ...
