Sound-producing muscles provide the opportunity of studying the limits of power production at high contractile frequencies. We used the work loop technique to determine the power available from the external oblique muscles in two related species of North American gray tree frog, Hyla chrysoscelis and Hyla versicolor. These trunk muscles contract cyclically, powering high-intensity sound product...

Regions of specialization for water absorption across the skin of Bufonid and Ranid anurans were identified by immunohistochemistry and Western blot analysis, using antibodies raised against arginine vasotocin (AVT)-stimulated aquaporins (AQPs) that are specific to absorbing regions of Hyla japonica. In Bufo marinus, labeling for Hyla urinary bladder-type AQP (AQP-h2), which is also localized i...

T H E ultimobranchial body of Hyla arborea L., Rana ridibunda Pall., Pelobates syriacus Boettger, and Bufo viridis Laur., the common anurans of Israel, is a paired organ, situated on both sides of the aditus laryngis. Its development runs parallel to the fluctuating activity of the thyroid (Boschwitz, 1960). (a) In the premetamorphic period of relative thyroid dormancy, the ultimobranchial body...

Trichoderma orientalis (T. orientalis) EU7-22 has a complete cellulase system and shows remarkable enzyme activity with high potential in the industry. Ace2 is an important transcriptional factor for hemicellulase expression reesei reesei). However, ace2 gene cannot be found genome of T. orientalis. Researches show that mechanism regulation keeps similarity up till now. So, this study, QM9414 w...

The introduction and expansion of the Asian yellow-legged hornet (Vespa velutina nigrithorax) in Europe poses concern for multiple reasons, including biodiversity conservation. In addition to predation native insects (e.g., bees wasps), this species may compete with hornets due an overlap their climatic trophic niches. aim study is investigate realised niche V. v. nigrithorax its response condi...

In Australia, outbreaks of clinical theileriosis caused by Theileria orientalis have been largely associated with the Ikeda genotype which can occur as a sole infection, or more commonly, as a mixture of genotypes. The most prevalent genotype, Chitose, frequently co-occurs with type Ikeda, however the role of this genotype in clinical disease has not been clearly established. Furthermore, the d...
