The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

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

This research innovatively illustrates baicalin’s multifaceted mechanisms in enhancing piglets’ intestinal health: modulating bile acid metabolism via probiotics, reinforcing tight junction proteins (ZO‐1/claudin), suppressing TLR4/NF‐κB‐mediated inflammation, whereas promoting growth and reducing diarrhea.

This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Feeding Ecology of Stream Invertebrates
Annual Review of Ecology and Systematics, 1979A review of various aspects of invertebrate-microbial interactions is presented. Food resources of stream invertebrates are distinguished by particle size (detritus), the presence of chlorophyll (periphyton), and high protein content (macrophytes). Invertebrate functional feeding groups such as shredders, collectors, scrapers, piercers, and predators ...

Hjort proposed that fishery year-class fluctuations are due mainly to variable larval mortality, and that most mortality is due to early starvation. Some larvae die because they do not find enough zooplankton to eat, but others may die because zooplankton cat them.

Abstract The foods taken by the various ratites and tinamous are described in the Species accounts. The diets of the large species have much in common, although they differ in detail simply because the birds live in different continents and h:we different foods available to them.
