From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

open access: yesThe Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

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

open access: yesThe 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

Effects of Combining Feed Grade Urea and a Slow-release Urea Product on Performance, Dietary Energetics and Carcass Characteristics of Feedlot Lambs Fed Finishing Diets with Different Starch to Acid Detergent Fiber Ratios. [PDF]

open access: yes, 2016
Recent findings have shown that microbial nitrogen flow and digestible energy of diets are increased when urea is combined with a slow-release urea (SRU) in diets with a starch to acid detergent fibre ratio (S:F) 4:1.

Effect of Beef Carcass Composition on Carcass Conformation

open access: yesNihon Chikusan Gakkaiho, 1990
牛枝肉の形状と枝肉を構成する組織との関係を黒毛和種2系統,ホルスタイン種,日本短角 種および交雑種の,合計122頭の去勢肥育牛を用いて検討した.各肥育牛は70-100kgの体重間隔で4段階にわたって屠殺し,左半丸枝肉について,23のサイズに関する測定値と筋肉,脂肪,骨および腱を含むその他の組織の各重量を求めた.サイズの測定値から求めた枝肉形状についての4つの主成分と23の枝肉測定値を従属変数とし,枝肉組織重量を独立変数として両者間の関係を,重回帰分析法により検討した.枝肉形状のうちのサイズを示す第1主成分と各組織との間には,いずれも高度に有意な関係が見られた.枝肉の薄さの因子である第2主成分は,骨が多く筋肉,脂肪の少ないものとの関係が大きかった.枝肉測定値に対する各組織の標準偏回帰係数から ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
