Peatlands in Croatia are rare, small in size and isolated habitats. Due to the abandonment of traditional land-management practices, and particularly to the progressive vegetation succession, they are critically endangered. Caddisfl y faunistics and ecology of peatlands in Croatia have never been studied. A total of seven caddisfl y taxa were collected in this study at three diff erent peatland...

We used airborne imaging spectroscopy and photon transport modeling to determine how biological invasion altered the chemistry of forest canopies across a Hawaiian montane rain forest landscape. The nitrogen-fixing tree Myrica faya doubled canopy nitrogen concentrations and water content as it replaced native forest, whereas the understory herb Hedychium gardnerianum reduced nitrogen concentrat...

Cryphonectria havanensis is a fungus associated with Eucalyptus species in Cuba and Florida (U.S.A.). Until recently, there have been no living cultures of C. havanensis and it has thus not been possible to assess its taxonomic status. Isolates thought to represent this fungus have, however, emerged from surveys of Eucalyptus in Mexico and Hawaii (U.S.A.). Results of this study showed that thes...

Potent inhibitory activity of the leaves of Myrica rubra against both chemical and enzymatic (tyrosinase and lipoxygenase) oxidation was found in our project to develop utility of unused and rarely used plant resources in the local area. A constituent analysis of the most active ethyl acetate-soluble part of a methanol extract of the leaves clarified the structures of eight major compounds. The...

The anti-ulcer activity of Methanolic extract Myrica nagi (Myricaceae) fruit MEMN was investigated in pylorus ligation and methanol-induced ulcer models Wistar rats. In both models, the common parameter determined index at doses 200,400 mg/kg p.o produced significant inhibition gastric lesions induced by Aspirin-induced ulcers & ligation-induced ulcers. (200, 400 mg/kg) showed a (P < 0.0...

The relationship between the expression of mitochondrial voltage-dependent anion channels (VDACs) and the protective effects of Myrica rubra Sieb. Et Zucc fruit extract (MCE) against carbon tetrachloride (CCl(4))-induced liver damage was investigated. Pretreatment with 50 mg kg(-1), 150 mg kg(-1) or 450 mg kg(-1) MCE significantly blocked the CCl(4)-induced increase in both serum aspartate amin...

The existence of martingale selectors for a multivalued supermartin-gale with continuous parameter is proved.We also prove the weak regularity of multivalued supermartingales.Using the regularity of Banach-valued martingales,we show a multivalued supermartingale has a cadlag modiication under Kuratowski convergence. x1. Introduction Multivalued martingales and supermartingales with discrete par...

Calibration of the Granier thermal dissipation technique for measuring stem sap flow in trees requires determination of the temperature difference (DeltaT) between a heated and an unheated probe when sap flow is zero (DeltaT(max)). Classically, DeltaT(max) has been estimated from the maximum predawn DeltaT, assuming that sap flow is negligible at nighttime. However, because sap flow may continu...

The present study deals two new alpheid shrimp species from the transisthmian Salmoneus ortmanni (Rankin, 1898) complex. Salmoneus alvarezi sp. nov. is described based on materials collected in Bahía Málaga, Colombia, and Punta Morales, Costa Rica, and is closely related to the western Atlantic S. ortmanni and S. wehrtmanni Anker, 2011. Salmoneus malagensis sp. nov. is described based on specim...
